+- stateful handles such as files, sockets, scanners, builders, and streams; +- capability-wrapped values such as `@locked`, `@shared`, `@local`, and + future package permissions; +- effectful boundaries such as file IO, network IO, process execution, time, + randomness, allocation, and blocking; +- tense-aware values, including snapshots, live state, historical values, + derived state, and streamed/current values where the language supports them. + +The user should be able to start with a high-level stateless API and only add +state, effects, capabilities, or tense-specific machinery when the program +actually needs it. + +## User-Facing Priority + +After composability, the stdlib's highest user-facing priority is to feel as +high-level as possible. + +This is true even when a traditional systems language would consider the API +"too convenient" or "not explicit enough." CLEAR is not trying to make every +program read like Zig, C, or Rust. CLEAR should give users Ruby/Elixir-level +ergonomics by default and expose systems-level detail only when that detail is +needed for correctness, performance, or capability control. + +The default bias is: + +- Prefer a high-level interface when the lower-level interface mainly exposes + implementation mechanics. +- Prefer Ruby/Elixir-style convenience when the operation has an obvious safe + default. +- Prefer explicit systems controls only when hiding them would create a major + correctness, performance, or security flaw. +- When a harder API is necessary, make it only slightly harder than the + high-level path and explain what additional control the user is getting. + +This means the stdlib should not force users to think about allocators, readers, +writers, buffers, file descriptors, backpressure, stream lifetimes, socket +polling, or scheduler integration for common code. Those concepts should exist, +but they should be opt-in. + +## What Counts As A Major Systems Flaw + +We should deviate from a high-level API only for major flaws, not for ordinary +systems-language taste. + +Major flaws include: + +- hidden unbounded memory growth in common usage; +- impossible or misleading resource lifetime semantics; +- data races or capability violations; +- effect/capability behavior that the compiler cannot track; +- performance cliffs that are large, common, and hard to diagnose; +- APIs that make deterministic compiler output unreliable; +- APIs that prevent a lower-level zero-cost path from existing. + +Non-major reasons are not enough by themselves: + +- "Zig would make the allocator explicit." +- "Java would force a stream object." +- "Rust would encode this as a trait-heavy iterator stack." +- "C would expose the buffer and length." + +Those can be valid implementation details. They are not automatically good +CLEAR user interfaces. + +## IO And Streams Are The Test Case + +File and network IO are the clearest examples. + +CLEAR should not make opening files or doing file/network IO as hard as Java or +Zig for ordinary users. A user should be able to write obvious high-level code: + +```ruby clear illustrative +text = fs.read("config.clear") OR RAISE; +lines = fs.readLines("users.txt") OR RAISE; +fs.write("out.txt", report) OR RAISE; +``` + +The same principle applies to pipelines. The pipeline system should default to +using streams internally where it can, because streaming is the right execution +strategy for IO and large inputs. The final result should be driven by an +explicit terminal or destination type. + +Illustrative shape: + +```ruby clear illustrative +users: User[] = (fs.readLines("users.csv") OR RAISE) + |> MAP { parseUser(_) } + |> SELECT { _.active?() }; +``` + +The implementation should be free to stream `users.csv` line by line. The user +should not need to opt into streaming just to avoid a bad implementation. But +because the assignment target is a list, the final value should collect into a +list. + +If the user wants a stream, hashmap, set, or another collection, they should ask +for it explicitly: + +```ruby clear illustrative +active_stream = (fs.readLines("users.csv") OR RAISE) + |> MAP { parseUser(_) } + |> SELECT { _.active?() } + |> AS_STREAM; + +users_by_id = (fs.readLines("users.csv") OR RAISE) + |> MAP { parseUser(_) } + |> COLLECT_MAP { _.id => _ }; + +unique_domains = (fs.readLines("emails.txt") OR RAISE) + |> MAP { domainOf(_) } + |> COLLECT_SET; +``` + +The exact names are not settled. The principle is settled: + +- streams are a preferred internal execution strategy; +- result shape comes from an explicit terminal or destination type; +- directory scans, globbing, and collection do not insert hidden sorts; +- systems programmers can request stream/control forms without fighting the + high-level API. + +Ordering is explicit: + +```ruby clear illustrative +files = fs.glob("src/**/*.cht") OR RAISE; +sorted = files |> ORDER_BY _; +``` + +`ORDER_BY` is the current explicit sort-by-key operator. A future `SORT` +shorthand for sorting by the singular value depends on the traits/interfaces +or duck-typed ordering decision. + +This is the kind of tradeoff CLEAR should make repeatedly. A systems language +might require explicit stream types everywhere. CLEAR should infer and use the +efficient strategy internally, then return the ergonomic shape by default. + +## Stateless And Stateful Pairs + +Many stdlib areas need both stateless and stateful APIs. + +The stateless form should be the default: + +```ruby +content = fs.read("input.txt"); +tokens = scanner.scanAll(source); +json = Json.parse(text); +``` + +The stateful form should appear when it buys something real: + +```ruby +file = fs.open("input.txt"); +stream = file.lines(); +scan = Scanner.new(source); +builder = StringBuilder.new(); +``` + +The stateful form should not be the only way to do common work. It exists for +large inputs, incremental processing, resource reuse, backpressure, explicit +cleanup, and performance-sensitive code. + +## Effects And Capabilities Should Be Visible, Not Noisy + +The compiler should know that `fs.read` has a file-read effect, allocates, and +can fail. The user should not have to spell all of that at every call site. + +Preferred posture: + +- Effects are inferred for normal code. +- Public package boundaries document effects. +- Strict modes can require effect declarations. +- Capability permissions are visible where they matter, especially package and + host boundaries. +- High-level APIs remain high-level unless the user opts into strict control. + +For example, `fs.read("config.clear")` should be easy. In a restricted package +or strict build, the compiler can still require that the package is allowed to +perform file reads. + +## Naming Bias + +Prefer names that read naturally in pipelines and UFCS: + +- Ruby/Elixir-style collection names: `map`, `select`, `reject`, `filterMap`, + `flatMap`, `find`, `any?`, `all?`, `reduce`; pipeline ordering uses + `ORDER_BY`. +- Ruby-style predicates when they are compact and obvious: `empty?`, + `present?`, `nil?`, `startsWith?`, `endsWith?`. +- Systems names only at systems boundaries: `open`, `close`, `flush`, `sync`, + `readInto`, `writeAll`, `reserve`, `capacity`. + +Avoid names that force users to learn the backing implementation before they +can write ordinary code. + +## Defaults + +Default choices should be optimized for high-level users: + +| Area | Default | Explicit lower-level path | +| --- | --- | --- | +| Pipeline result | destination type or explicit terminal | `AS_STREAM`, `COLLECT_LIST`, `COLLECT_MAP`, `COLLECT_SET`, fixed array | +| File read | read whole text or lines | open handle, stream lines, read bytes, read into buffer | +| Network read | message/bytes helper where possible | socket/client resource and stream control | +| Strings | UTF-8 text operations | byte buffers and byte indexing | +| Errors | `!T` fallibility with `OR` propagation | named error taxonomy and explicit result handling | +| Effects | inferred and documented | strict declarations and package permissions | +| Allocation | implicit safe allocation | reserve/capacity/allocator-aware APIs | +| Mutation | immutable/new collection transforms | explicit mutating names | + +The lower-level path must exist. It should not be the first thing users see. + +## Key Decisions Before Self-Host Implementation + +The self-host project can implement a lot with existing intrinsics and thin +source packages, but these decisions should be made before most stdlib work +lands: + +1. **Pipeline result defaults.** Pipelines use streams internally where + practical and collect according to explicit terminal or destination type. +2. **Explicit collection request syntax.** Choose names and syntax for + `AS_STREAM`, `COLLECT_LIST`, `COLLECT_MAP`, `COLLECT_SET`, and typed + collection targets. +3. **Error model.** Prototype stdlib APIs expose native `!T` fallibility and + `OR` propagation. The remaining decision is the named error taxonomy and + future relationship to `Result`. +4. **Effect visibility.** Decide which effects are public stdlib contracts for + self-host packages: file read/write, process/env, network read/write, time, + random, allocation, blocking, and extern. +5. **Capability permissions.** Decide how packages declare or receive authority + to touch files, network, processes, environment, clocks, and randomness. +6. **Resource lifetime model.** Decide how high-level APIs auto-close resources + and how stateful handles express cleanup, ownership, borrowing, and escape. +7. **Stream lifetime and backpressure.** Decide how streams interact with file + handles, sockets, fibers, scheduler suspension, and collection boundaries. +8. **Tense integration.** Decide how stdlib APIs expose snapshots, live views, + historical values, and streamed current values without making ordinary APIs + noisy. +9. **Stateless/stateful API pairing.** Decide the naming convention for simple + convenience functions versus explicit handle/builder/scanner/stream APIs. +10. **String and bytes split.** Decide byte indexing, codepoint indexing, + invalid UTF-8 handling, and conversions between `String` and byte buffers. +11. **Ordering.** Directory listing and globbing should be unsorted streams by + default. Decide the explicit ordered variants and future `SORT`/ordering + interface for maps, sets, JSON object generation, and diagnostics. +12. **Generic and iterator model.** Decide how collection functions specialize + without importing a class/trait/interface model that CLEAR does not want. +13. **Mutation convention.** Decide how mutating collection/string operations + are named and how aliasing/capability hazards are rejected. +14. **Docs stability labels.** Decide the public status vocabulary for planned, + prototype, self-host required, intrinsic today, and stable APIs so docs do + not imply premature compatibility. + +These decisions should not block every tiny wrapper, but they should block wide +stdlib implementation.

We should +publish the planned stdlib shape on the GitHub Pages site so interested users +can see the direction, but deliberately avoid implementing most of it until the +core contracts are stable. A documented API is a design artifact; it is not a +compatibility promise until explicitly marked stable. + +The default implementation language should be CLEAR. Zig belongs at hard +boundaries: syscalls, allocator and arena machinery, process and network +integration, runtime scheduler hooks, byte-level performance kernels, and +libraries where reimplementation would distract from compiler self-hosting. + +The public API should borrow the useful parts of Ruby and Elixir: + +- Ruby names where they are compact and familiar: `empty?`, `any?`, `map`, + `select`, `reject`, `join`, `split`, `starts_with?`. +- Elixir's functional bias where it avoids object-model baggage: first-class + collection transforms, explicit accumulator functions, explicit match + results, and pipelines. +- Rust/Zig style at capability and system boundaries: explicit ownership, + explicit failure, explicit allocation/effects, no hidden global state. + +CLEAR is closer to C/Zig plus accessible functional programming than to Java or +Ruby. The stdlib should therefore expose structs, free functions, UFCS-friendly +methods, and pipeline primitives. It should not smuggle in classes, mixins, +traits, or implicit dynamic dispatch to make Ruby source feel native. + +## Existing Design + +Today the stdlib has two different surfaces: + +- `src/ast/std_lib.rb` is a compact intrinsic registry. It describes built-in + functions and methods, their types, Zig templates, allocation behavior, + ownership behavior, mutating receivers, suspension, bytecode lowering, and + resource schemas. +- `stdlib//src/lib.cht` is the first-party package layout. The module + importer auto-resolves `REQUIRE "pkg:"` after explicit `--pkg` paths. + At the moment only `pkg:testing` exists, and it is a smoke-test skeleton. + +That split is the right direction: + +- Source packages should hold normal library APIs that can be authored, + tested, documented, and eventually self-hosted in CLEAR. +- The intrinsic registry should stay small and boundary-oriented. Its job is to + attach compiler-known contracts to operations that cannot be expressed as + ordinary CLEAR yet, or that need direct runtime/Zig support. + +Existing intrinsic coverage already includes list/map/set/pool operations, +string helpers, numeric predicates, filesystem helpers, TCP resources, +time/sleep/random, profiling helpers, and testing-oriented predicates. The +stdlib design should migrate higher-level policy out of this registry over +time, not expand it into a general standard library authoring language. + +The effects design already points in the same direction. Allocation, blocking, +external calls, file read/write, and network read/write must be tracked by the +compiler. Stdlib APIs should be one of the main places those contracts are made +visible and stable. + +The public documentation site already has the right publishing path: + +- `docs/` is the source of truth for public site content. +- `docs/agents/` is intentionally excluded from the site and stays internal. +- `tools/gen_site.rb` maps public markdown under `docs/` into Zola content under + `site/content/docs/`. +- `.github/workflows/pages.yml` runs `ruby tools/gen_site.rb`, then `zola build` + and deploys `site/public` to GitHub Pages. + +Therefore the stdlib plan needs both: + +- `docs/agents/stdlib-design.md`: internal implementation, migration, and + decision record. +- `docs/stdlib.md`: public planned API/spec page rendered by the Zola site. + +## External Launch Lessons + +Primary references: + +- Go 1 release notes: https://go.dev/doc/go1 +- Rust 1.0 announcement: https://blog.rust-lang.org/2015/05/15/Rust-1.0/ +- Rust `std` crate documentation: https://doc.rust-lang.org/std/ +- Zig download history: https://ziglang.org/download/ +- Zig language reference stdlib section: https://ziglang.org/documentation/0.16.0/ +- Elixir `Enum`: https://hexdocs.pm/elixir/Enum.html +- Ruby `Enumerable`: https://ruby-doc.org/3.4.1/Enumerable.html + +### Go + +Go 1 treated the standard library as a stable product foundation. Its launch +surface included broad batteries: archives, compression, crypto, encoding +packages such as JSON/XML/CSV, `fmt`, `io`, `os`, `path/filepath`, `net`, +`http`, `regexp`, `strconv`, `strings`, `sync`, `time`, and `testing`. Go also +used the Go 1 moment to regularize package names and APIs, then made stability +the central promise. + +Lesson for CLEAR: launch stability matters more than breadth. A broad stdlib is +useful, but only after the language's ownership, capability, effect, error, +string, and package contracts are stable. Do not copy Go's package count before +copying its commitment to boring, consistent behavior. + +### Rust + +Rust 1.0 launched around a smaller, systems-oriented core: `Option`, `Result`, +`Vec`, `String`, slices, iterators, collections, formatting, I/O, filesystem, +networking, paths, process, threads, synchronization, time, and macros. Rust's +1.0 announcement emphasized stability after pre-1.0 churn, while leaving many +higher-level libraries to crates. + +Lesson for CLEAR: a strong core plus package ecosystem beats a huge unstable +stdlib. CLEAR should copy Rust's explicit error and ownership posture, but not +copy trait-heavy API designs that conflict with CLEAR's "structs plus UFCS" +direction. + +### Zig + +Zig's early public history was pre-1.0 and intentionally unstable; the official +download page lists 0.1.1 in 2017 with language reference and source release, +while standalone standard-library docs appear in later release rows. Current +Zig documentation describes std as common algorithms, data structures, and +definitions, and the stdlib is rendered from the local compiler distribution +with `zig std`. + +Lesson for CLEAR: Zig's useful influence is not API breadth. It is explicit +allocation, explicit platform boundaries, compile-time specialization, and a +small amount of runtime magic. CLEAR should use Zig as the model for boundary +honesty, not for exposing every low-level helper directly to users. + +## Design Principles + +1. Document first, implement second. Public stdlib docs should mark planned, + prototype, and stable APIs distinctly so people can track the direction + without being invited to depend on unfinished surfaces. +2. Implement in CLEAR unless the boundary forces Zig. +3. Keep zero-cost translations zero-cost. Do not add a Grumpy-style runtime to + support source-language behavior that CLEAR does not want. +4. Make effects part of stdlib contracts. File, network, process, allocation, + blocking, randomness, and time are observable capabilities, not casual + helpers. +5. Prefer explicit ordering for compiler tooling. Map/set iteration and + filesystem traversal should stay natural unless output order matters; use + `ORDER_BY` or dedicated ordered variants when deterministic output is part + of the contract. +6. Use UFCS and pipelines as the ergonomic layer. A function should be usable as + `map(xs, fn)` and `xs.map(fn)` or `xs |> MAP { ... }` where the compiler can + lower it efficiently. +7. Avoid object-model compatibility. No classes, mixins, singleton classes, + dynamic method tables, or hidden `respond_to?` equivalents in stdlib APIs. +8. Make nil/failure explicit. Prefer `?T`, `Result`/error unions, or named + failure-return APIs over implicit Ruby exceptions or global match state. +9. Preserve byte/string clarity. Unicode text and byte buffers must have + distinct contracts even when backed by `[]u8`. +10. Keep the prelude small. Pervasive names should be limited to primitives, + predicates, basic formatting, and collection operations that read naturally. + +## Documentation First + +The first stdlib epic is a documentation pipeline and public spec, not a +library implementation. + +The source of truth is authored stdlib documentation embedded in +`tools/stdlib_docs.rb` and generated into split public pages under `docs/`. +This keeps planned APIs close to implementation metadata while still publishing +readable package pages through the static site generator. + +The public docs should include: + +- A clear "planned, not stable" banner. +- A package map for `core`, `collections`, `string`, `bytes`, `regex`, + `scanner`, `fs`, `path`, `json`, `cli`, `process`, `env`, `time`, `random`, + `math`, `testing`, and `network`. +- API sketches with status tags: `planned`, `prototype`, `intrinsic today`, + `self-host required`, and `stable`. +- Effect and capability notes on every host-facing package. +- Examples that read like CLEAR, but are labelled illustrative unless they + compile today. + +Do not generate real `stdlib//src/lib.cht` packages for every planned +surface yet. A wide stub package tree would make it look like the stdlib is +available and would encourage early dependency on APIs we still expect to +change. Until a package is ready for compiler or launch use, the public docs +should be the artifact. + +The implementation gate for a documented API is: + +1. The relevant language decision gates in this document are resolved. +2. The API has at least one compiler self-host or launch use case. +3. The package has integration tests through `REQUIRE "pkg:"`. +4. The public docs can mark the API `prototype` or `stable` without misleading + users. + +## Package Shape + +First-party packages should follow the existing layout: + +```text +stdlib/ + collections/src/lib.cht + string/src/lib.cht + fs/src/lib.cht + path/src/lib.cht + regex/src/lib.cht + json/src/lib.cht + cli/src/lib.cht + testing/src/lib.cht +``` + +They should be imported as: + +```clear +REQUIRE "pkg:collections"; +REQUIRE "pkg:fs" AS fs; +``` + +Core/prelude functions may remain compiler-known for now, but new non-boundary +stdlib work should prefer source packages. A package API that cannot be written +in CLEAR should call one or more narrow intrinsics rather than becoming a large +intrinsic row itself. + +## CLEAR vs Zig Boundary + +| Area | Prefer CLEAR | Use Zig only for | +| --- | --- | --- | +| Collection transforms | `map`, `filter`, `reject`, `reduce`, `ORDER_BY` wrappers and policies | Backing storage primitives, hashing kernels, sort kernels if needed | +| Strings | API composition, trimming/splitting policy, formatting wrappers | UTF-8 validation/iteration kernels, allocation-heavy builders | +| Regex/scanner | Explicit `Match` and `Scanner` API surface | Regex engine, DFA/NFA execution, byte scanning hot loops | +| Files/path | Path API, ordering policy, error normalization | Syscalls, open/read/write/stat, platform path quirks | +| Network | TCP/UDP resource wrappers, capability gating | Sockets, poll/epoll/io_uring integration, TLS primitives | +| Process/env | Typed option parser, command descriptions | Spawn/exec/wait, env access, stdio pipes | +| Time/random | Duration/time wrappers, deterministic test hooks | OS clocks, entropy, crypto RNG | +| Testing | Assertions, diffs, fixtures, golden/oracle helpers | Test runner integration, leak hooks, process isolation | + +## Critical Components + +### Core And Prelude + +Launch surface: + +- `Bool`, integer and float helpers, `String`, byte slices, ranges, `?T`, + result/error union conventions, `NIL`, `TRUE`, `FALSE`. +- Basic predicates: `nil?`, `present?`, `empty?`, `any?`, `zero?`, + `positive?`, `negative?`, `between?`, `closeTo?`. +- Formatting and printing: `format`, `print`, `debugPrint`, `toString`, + `toInt`, `toFloat`. +- Assertions that are useful outside `pkg:testing`: `ASSERT`, `panic`, + `unreachable`. + +Self-host requirement: P0.

File/path/dir APIs used by the Ruby compiler: read, read lines, write, + existence checks, path join/expand/basename/dirname, glob, directory exists, + mtime, symlink helpers if still present. +2. Collections and transforms used by the transpiler output: list, map, set, + `each`, `map`, `select`, `reject`, `filterMap`, `flatMap`, `find`, `any?`, + `all?`, `sum`, `count`, `ORDER_BY`, `keys`, `values`, `pairs`, + indexed iteration, and accumulator iteration. +3. Strings and scanners for lexer/parser code: byte access, codepoint count, + split lines, substring, replace, regex escape, explicit match result, + scanner position and matched text. +4. JSON for metadata and tooling. +5. CLI and process helpers for compiler commands and test harnesses. +6. Testing package robust enough for oracle translation tests. +7. Diagnostic formatting and source-span helpers. + +This is the minimum practical stdlib for self-hosting, not the full launch +stdlib. + +## Decisions To Make Before Implementing Only Self-Host Needs + +These should be settled before building a narrow compiler-only stdlib, because +they affect public API shape and will be expensive to unwind: + +1. Error taxonomy and `Result` relationship. Prototype APIs use native `!T` + fallibility and `OR` propagation. +2. Effect names and enforcement for file, network, process, env, time, random, + blocking, allocation, and extern calls. +3. Capability permissions for packages: how a package declares it may read + files, write files, open sockets, spawn processes, or read environment. +4. Unicode/string indexing semantics. +5. Byte buffer type and conversion rules between `String` and bytes. +6. Iterator/pipeline model for collection transforms without traits or classes. +7. Generic specialization model for collection functions and maps/sets. +8. Ordering policy for maps, sets, JSON objects, and diagnostics. Directory + listings and globbing are unsorted streams by default; deterministic output + opts into `ORDER_BY` or ordered helpers. +9. Regex subset and explicit match-result data model. +10. Package visibility, versioning, and stdlib compatibility promise. +11. Test declaration lowering: compiler syntax vs `pkg:testing` library calls. +12. Intrinsic registry ownership: what remains intrinsic after source packages + exist. + +## Roadmap + +### Phase 0: Public Stdlib Spec Site + +- Add `docs/stdlib.md` as the public planned stdlib spec. +- Keep `docs/agents/stdlib-design.md` as the internal decision record. +- Use the existing Zola path: `ruby tools/gen_site.rb` generates + `site/content/docs/stdlib.md`, and GitHub Pages publishes it via + `.github/workflows/pages.yml`. +- Add status labels to every listed package/API so unfinished surfaces are not + mistaken for supported code. +- Do not create package implementations for speculative APIs in this phase. + +### Phase 1: Boundary Inventory + +- Audit `src/ast/std_lib.rb` and classify each entry as core/prelude, + source-package wrapper, or permanent intrinsic. +- Add a short owner comment to permanent intrinsics explaining why CLEAR source + cannot express it yet. +- Keep `pkg:testing` as the package smoke test and add one more trivial package + to prove multi-package stdlib resolution. + +### Phase 2: Self-Host Foundation + +- Build `pkg:collections`, `pkg:string`, `pkg:fs`, `pkg:path`, and + `pkg:testing` around existing intrinsics. +- Add oracle tests that use the same API shapes emitted by `ruby-to-clear`. +- Keep all APIs deterministic unless explicitly documented otherwise. +- Do not add Ruby compatibility shims. The transpiler should emit CLEAR-shaped + APIs or TODO comments. + +### Phase 3: Scanner, Regex, JSON, CLI + +- Add `pkg:scanner` or `pkg:regex` with explicit match state. +- Add JSON parse/generate with stable object output. +- Add typed CLI option parsing. +- Add enough process/env APIs for compiler tooling, with effects. + +### Phase 4: Launch Hardening + +- Freeze naming and compatibility for P0/P1 packages. +- Move high-level policy out of `src/ast/std_lib.rb`. +- Add effect declarations to public package APIs when STRICT mode supports it. +- Add docs and examples for the launch API, not just compiler self-host usage. + +### Phase 5: Optional Breadth + +- Network beyond TCP basics. +- HTTP/TLS. +- Compression/archive. +- Crypto. +- CSV/YAML/TOML. +- Advanced time/date. + +These should wait until the core effect, capability, string, error, and package +contracts are stable. + +## Immediate Next Work + +1. Publish the planned stdlib spec at `docs/stdlib.md` so the Zola site exposes + the roadmap without creating usable packages prematurely. +2. Verify `ruby tools/gen_site.rb` can generate the public page for the GitHub + Pages workflow. +3. Create a machine-readable inventory of current intrinsic registry entries: + name, types, allocation, mutating receiver, effect/suspension, backing Zig + helper, and proposed package owner. +4. Convert the self-host stdlib TODO into package-level issue lists under this + design: + `collections`, `string`, `fs`, `path`, `regex/scanner`, `json`, `cli`, + `testing`. +5. Implement only the source-package wrappers needed by the self-host path after + the public spec and relevant decision gates exist. +6. Add integration tests that compile small CLEAR programs using each package + through `REQUIRE "pkg:"`. +7. Use the ruby-to-clear audit as the coverage driver: if the transpiler can + emit a direct CLEAR stdlib call for a safe Ruby shape, add that stdlib shape + before hand-porting compiler code. diff --git a/docs/stdlib.md b/docs/stdlib.md new file mode 100644 index 000000000..76e267b7d --- /dev/null +++ b/docs/stdlib.md @@ -0,0 +1,56 @@ + + +# CLEAR Standard Library + +> [!WARNING] +> This is the current **planned** CLEAR stdlib design.

CLEAR should expose Ruby/Elixir-level ergonomics by +default and expose systems-level detail only when that detail is needed +for correctness, performance, or capability control. + +We deviate from high-level interfaces for major flaws: + +- hidden unbounded memory growth in common usage; +- impossible or misleading resource lifetime semantics; +- data races or capability violations; +- effect/capability behavior that the compiler cannot track; +- performance cliffs that are large, common, and hard to diagnose; +- APIs that make deterministic compiler output unreliable; +- APIs that prevent a lower-level zero-cost path from existing. + +Ordinary systems-language preference is not enough by itself. "Zig would +make the allocator explicit" or "Java would force a stream object" may be +true, but those are not automatically good CLEAR user interfaces. + +## IO And Streams + +File and network IO are the test case. CLEAR should not make ordinary IO +as hard as Java or Zig. + +```ruby clear illustrative +text = fs.read("config.clear") OR RAISE; +lines = fs.readLines("users.txt") OR RAISE; +fs.write("out.txt", report) OR RAISE; +``` + +Pipelines should default to using streams internally where that is the +efficient strategy, especially for IO and large inputs. A pipeline can be +collected implicitly by its destination type, or explicitly with a +terminal such as `COLLECT_LIST`, `COLLECT_SET`, `COLLECT_MAP`, or +`AS_STREAM`. + +```ruby clear illustrative +users = (fs.readLines("users.csv") OR RAISE) + |> MAP { parseUser(_) } + |> SELECT { _.active?() }; +``` + +The implementation may stream `users.csv` line by line. Because the +assignment target is a list, the final value collects into that list. + +Users who want a stream, map, set, or another collection request it +explicitly: + +```ruby clear illustrative +active_stream = (fs.readLines("users.csv") OR RAISE) + |> MAP { parseUser(_) } + |> SELECT { _.active?() } + |> AS_STREAM; + +users_by_id = (fs.readLines("users.csv") OR RAISE) + |> MAP { parseUser(_) } + |> COLLECT_MAP { _.id => _ }; + +unique_domains = (fs.readLines("emails.txt") OR RAISE) + |> MAP { domainOf(_) } + |> COLLECT_SET; +``` + +The exact names are not final. The principle is final: stream internally +where practical, collect from the explicit terminal or destination type, +and never insert hidden sorts or other semantic work during collection. + +Ordering is explicit. Directory scans and globbing should be unsorted +streams unless the user asks otherwise: + +```ruby clear illustrative +files = fs.glob("src/**/*.cht") OR RAISE; +sorted = files |> ORDER_BY _; +``` + +A future `SORT` shorthand may sort by the singular value, but that +depends on the traits/interfaces or duck-typed ordering decision.

Confirm pipeline result defaults: stream internally where practical; + collect according to explicit terminal or destination type. +2. Choose explicit collection target syntax: `AS_STREAM`, `COLLECT_LIST`, + `COLLECT_MAP`, `COLLECT_SET`, and typed collection targets. +3.

Unlike empirical runtime measurements (which suffer heavily from JIT noise, GC pauses, and the need for scaling benchmark data), a static approach mathematically analyzes the AST of a method to compute a theoretical worst-case time complexity. + +Espalier is uniquely positioned to achieve this because it can ingest concrete type evidence from `nil-kill`. By combining `fact-mine`'s structural AST extraction with `nil-kill`'s type resolution, Espalier can accurately resolve method calls to their host classes (even with dynamic dispatch and operator overloading) and apply algorithmic complexity rules. + +## Core Architecture + +The static Big-O analyzer relies on three pillars: +1. **The Stdlib Complexity Registry** +2. **Type Resolution via Nil-kill** +3. **AST Complexity Multiplication** + +### 1. The Stdlib Complexity Registry +To statically evaluate Big-O, Espalier must know the complexity of standard library functions that execute non-linear C-loops in the Ruby VM. + +Because we assume an implicit default of $O(1)$ for unknown operations, we do not need to map the entire standard library. We only need to map the ~150 core methods that operate in $O(N)$ or worse. + +A YAML registry (`stdlib_complexity.yml`) will map these behaviors: +```yaml +Array: + each: O(N) + map: O(N) + select: O(N) + flatten: O(N) + sort: O(N log N) + "-": O(N * M) # Subtraction +String: + scan: O(N) + gsub: O(N) + split: O(N) + "+": O(N) +Hash: + merge: O(N) + transform_values: O(N) +``` +*(All unmapped methods like `Hash#[]` or `Integer#+` default to $O(1)$).* + +### 2. Type Resolution (Handling Operator Overloading) +When Espalier encounters an AST node for `a + b`, it cannot blindly apply a complexity rule. If `a` is an `Integer`, it is $O(1)$. If `a` is a `String`, it is $O(N)$. + +Espalier will use the injected `nil-kill` evidence (`--nil-kill FILE`) to query the resolved type of `a`. +- If `nil-kill` proves `a` is `String`, Espalier consults the registry for `String#+` and assigns $O(N)$. +- If `nil-kill` cannot prove the type (or it resolves to `Integer`), it defaults to $O(1)$. + +### 3. AST Complexity Multiplication +The analysis walks the AST of a given method from the inside out, multiplying complexities when nested inside block constructs. + +**Rules:** +1. **Sequential Statements:** Added together. $O(N) + O(1) = O(N)$. +2. **Standard Loops (`while`, `for`):** The body's complexity is multiplied by $O(N)$. +3. **Block Iterators (`.each do`, `.map do`):** The registry flags the iterator as $O(N)$. The AST engine multiplies the iterator's complexity by the complexity of the block's body. + - Example: `.each { |x| x.gsub(...) }` $\rightarrow O(N_{each}) \times O(N_{gsub}) = O(N^2)$. +4. **User-Defined Method Calls:** If a method calls another user-defined method, Espalier looks up the pre-calculated Big-O of the callee and substitutes it. + +## Output and Diagnostics +Espalier will rank methods by their theoretical complexity and emit architectural warnings for highly non-linear constraints. + +**Example Report Output:** +> **[Complexity Constraint]** `SyntaxOracle#project_document` is $O(N^2)$. +> **Why:** The method calls `Array#each` ( $O(N)$ ) on `line 42`, which internally calls `String#scan` ( $O(N)$ ) on `line 44`. This forces the caller to manage quadratic scaling. Consider memoization or a specialized parser. + +## Why This Works Here +Building static Big-O analyzers for dynamic languages is traditionally impossible because of the lack of static types (which breaks stdlib mapping). By leveraging `nil-kill` as a type-oracle, Espalier bypasses the dynamic dispatch problem entirely, making this an extremely high-leverage architectural addition. diff --git

Empirical Big-O Analysis for `nil-kill` + +## Overview +This document outlines a proposed architecture for adding empirical Big-O complexity analysis (time and space) to `nil-kill`. Currently, `nil-kill` traces type boundaries, container shapes, and call edges, but it explicitly does not track input sizes or execution resources. + +Adding Big-O bounds estimation requires mapping the relationship between an input's size ($N$) and the resulting cost (execution time or memory allocations). Since static analysis of Ruby for algorithmic complexity is notoriously intractable due to its dynamic dispatch, empirical runtime measurement is a viable path forward to finding a lower-bound on complexity. + +## Estimated Effort +Building this natively into `nil-kill` without heavy external math dependencies would require roughly **300 to 400 Lines of Code (LoC)**. While the line count is small, the mathematical complexity and required noise-filtering heuristics are high. + +## Proposed Architecture + +### 1. Ruby Tracer Modifications (`lib/nil_kill/runtime_trace.rb`) +The tracer must be updated to capture size and time metrics without ruining application performance. + +* **Size Extraction ($N$):** + During `record_call`, `nil-kill` already samples parameters. We would add a safe check: `if value.respond_to?(:size) || value.respond_to?(:length)`, recording the integer size. For multiple collections, we can track the max size or a combined size matrix. +* **Cost Measurement (Time/Space):** + * *Time:* Capture `Process.clock_gettime(Process::CLOCK_MONOTONIC)` at `record_call` (entry) and `record_return` (exit). The delta is the execution cost. + * *Space (Optional but powerful):* Use `GC.stat(:total_allocated_objects)` diffs to measure memory pressure scaling. +* **Data Aggregation (Reservoir Sampling):** + We cannot store millions of $(N, Cost)$ tuples per method in memory. Instead, we should bucket samples (e.g., maintaining the median cost for $N \in [0, 10]$, $N \in [11, 100]$, $N \in [101, 1000]$). +* **JSON Serialization:** + Update the final trace output to emit a `complexity_samples` map containing `[N, Cost]` tuples for each method frame. + +### 2. Rust Inference Engine (`src/`) +The Rust engine will parse the empirical samples and map them to theoretical curves. + +* **Schema Extension:** Update `schemas.rs` to ingest `complexity_samples`. +* **Outlier Rejection (Critical):** + Ruby runtime data is heavily polluted by Garbage Collection pauses, JIT warmup, and thread scheduling. Before curve fitting, the engine must discard the top percentile of outliers (e.g., stripping anything $> 1.5 \times \text{IQR}$). +* **Curve Fitting / Regression Algorithm:** + Implement Least Squares Regression to fit the filtered $(N, Cost)$ points against standard complexity shapes: + * $O(1)$: $Cost = c$ + * $O(\log N)$: $Cost = c \cdot \log(N)$ + * $O(N)$: $Cost = c \cdot N$ + * $O(N \log N)$: $Cost = c \cdot N \log(N)$ + * $O(N^2)$: $Cost = c \cdot N^2$ + + The algorithm computes the $R^2$ (coefficient of determination) for each curve model. The model with the highest $R^2$ that exceeds a minimum confidence threshold (e.g., $R^2 > 0.85$) wins. + +### 3. Reporting and Diagnostics +If a method exhibits highly nonlinear scaling (e.g., fitting cleanly to $O(N^2)$), the Rust engine emits a new `Action` diagnostic. + +For example, this could be surfaced in `nil-kill` as: +> **Warning:** `process_users` strongly scales $O(N^2)$ based on parameter `users` (Confidence: 0.94). Check for nested loops or repeated linear array scans. + +## Challenges +* **JIT Noise:** YJIT gets faster over time. Early samples (where $N$ might be small) could take significantly longer than later samples (where $N$ is large), inadvertently presenting an inverted curve. We may need to discard the first $X$ samples per method to let the JIT stabilize. +* **Multi-Parameter Methods:** A method taking two arrays (`arr1`, `arr2`) has two axes of $N$. Doing multi-variable regression (e.g., $O(N \times M)$) expands the mathematical footprint considerably. diff --git a/gems/nil-kill/docs/agents/z3-type-inference-design.md b/gems/nil-kill/docs/agents/z3-type-inference-design.md new file mode 100644 index 000000000..f5e33c0a1 --- /dev/null +++ b/gems/nil-kill/docs/agents/z3-type-inference-design.md @@ -0,0 +1,113 @@ +# Design: Global Subtyping Constraint Solving in Z3 + +This document outlines the design for upgrading `nil-kill`'s type inference engine to use a Z3-based constraint solver over a subtyping lattice. By translating the type inference problem into a Satisfiability Modulo Theories (SMT) problem, we can solve circular type dependencies across complex AST/MIR node classes. + +--- + +## 1.

SMT2 Encoding Specification + +### A. Type Representation +Each type (including primitive classes, standard library classes, project AST/MIR classes, and `T.nilable` unions) is represented as a unique integer constant in Z3: + +```smt2 +(declare-sort Type) +; Declare concrete type constants +(declare-const T_untyped Int) +(declare-const T_NilClass Int) +(declare-const T_AST_Node Int) +(declare-const T_AST_Identifier Int) +(declare-const T_AST_Assignment Int) + +; Define ID values +(assert (= T_untyped 0)) +(assert (= T_NilClass 1)) +(assert (= T_AST_Node 2)) +(assert (= T_AST_Identifier 3)) +(assert (= T_AST_Assignment 4)) +``` + +### B. Transitive Subtyping Lattice Predicate +We define a transitive subtyping relation `is-sub` over the type constants. The lattice relations are extracted from the class declarations: + +```smt2 +(define-fun is-sub ((a Int) (b Int)) Bool + (or + (= a b) ; Reflexivity + (= b T_untyped) ; T.untyped is the top of the lattice (every type is a subtype of T.untyped) + (and (= a T_AST_Identifier) (= b T_AST_Node)) ; Subclassing relation + (and (= a T_AST_Assignment) (= b T_AST_Node)) + ; ... nilable connections + )) +``` + +### C. Type Variables for Untyped Slots +Every untyped parameter, return, field, and local variable is declared as an SMT variable: + +```smt2 +(declare-const var_AST_Assignment_value Int) ; The type of AST::Assignment#value +(declare-const var_MIR_Ident_name Int) ; The type of MIR::Ident#name +``` + +### D. Constraint Assertions +Constraints are fed into the solver from three distinct sources: + +1. **Concrete/Existing Types (Equality)**: + ```smt2 + (assert (= var_AST_Assignment_name T_AST_Identifier)) + ``` +2. **Assignments & Data Flow (Subtyping)**: + For every assignment statement (e.g. `@value = expr` inside `AST::Assignment`), we assert that the RHS type is a subtype of the LHS field type: + ```smt2 + (assert (is-sub Type_expr var_AST_Assignment_value)) + ``` +3. **Method Call Sites (Interface Bounds)**: + When passing an argument `arg` to a parameter `param`: + ```smt2 + (assert (is-sub Type_arg Type_param)) + ``` + +--- + +## 3. Implementation Effort & Impact Analysis + +### Feature 1: SMT2 Type Lattice Generator +- **Description**: Parses class declarations from the static index, constructs the type hierarchy DAG, and generates the transitive `is-sub` predicate matching the Sorbet/Ruby subtyping rules. +- **Estimated Work**: **Medium (2-3 days)**. The parser logic is already present in FactMine/Decomplex; we only need to map the output class hierarchies to SMT2 assertions. +- **Catch Rate (Impact)**: **~40% of Struct/Ivar Slots**. This allows Z3 to resolve AST/MIR subclass fields (like `AST::Assignment#name`) by proving that the subclass type is compatible with parent interfaces without causing type redefinition errors. + +### Feature 2: Static Data-Flow Assignment Constraint Parser +- **Description**: Traverses assignment nodes (`@ivar = val`, `var = val`) and local flow variables to emit constraint equations to the Z3 solver. +- **Estimated Work**: **High (5-7 days)**. Requires walking local variable assignment scopes and tracking fields across class scopes to generate constraint relations. +- **Catch Rate (Impact)**: **~75% of Pending/Propagation Gaps**. Resolves the propagation gaps where field values are forwarded from parameter initializers or return values across method boundaries. + +### Feature 3: Optimization Objective (Specificity Maximizer) +- **Description**: By default, `T.untyped` satisfies all subtyping constraints. To prevent the solver from returning `T.untyped` for every variable, we use Optimization SMT (using Z3's `maximize` or `minimize`) to assign high cost weights to `T.untyped` and low cost weights to specific subclass nodes. +- **Estimated Work**: **Medium (2 days)**. Requires switching the solver invocation to use `(maximize Type_Var)` equations or a customized weight function over type IDs. +- **Catch Rate (Impact)**: **Inherent requirement**. Without this, the solver will trivially default to `T.untyped` for all variables. + +--- + +## 4.

The first milestone must +recover structure before optimizing smaller call translations. + +## Ordered Epics + +### 1. Preserve Ruby Module Structure Without Designing Namespaces + +Audit signal: + +- `ModuleNode`: 120 unsupported output sites. +- Many large files are 0% useful because a top-level Ruby `module` is + unsupported. + +Implementation: + +- Add `ModuleNode` lowering that emits a stable migration/comment boundary and + translates the body. +- Do not create a Ruby module runtime, trait/interface system, or new namespace + mechanism from the transpiler. +- Preserve nested module names for TODO locations and collision diagnostics. +- Emit flat declarations where that is valid CLEAR. If flattening creates a + collision or ambiguity, emit a localized TODO instead of choosing a new + namespacing scheme. +- Treat mixin declarations (`include`, `extend`) as metadata or localized TODOs, + not runtime emulation. + +Acceptance: + +- `ModuleNode` disappears from unsupported-output audit results. +- Large files under `src/mir`, `src/annotator`, `src/ast`, `src/backends`, + `src/semantic`, and `src/lsp` become partial instead of fully commented. +- The emitted CLEAR does not rely on a new language-level namespace decision. + +Expected impact: + +- This is the highest-leverage step. It should reclaim tens of thousands of LoC + because it unlocks translation inside top-level Ruby modules. + +### 2. Support Keyword Arguments And Keyword Parameters + +Audit signal: + +- `KeywordHashNode`: 439 unsupported output sites. +- `ParametersNode`: 121 unsupported output sites. +- Call argument shapes include 5,730 `args=1+kw` calls and 1,043 `args=3+kw` + calls. + +Implementation: + +- Stop rejecting every `KeywordHashNode` at call entry. +- Lower simple keyword calls into direct CLEAR named arguments or struct-style + fields where the target call shape is known. +- Support required and optional keyword parameters in `DefNode` signatures. +- Fail closed on keyword splats and ambiguous forwarding. +- Add negative tests for keyword rest, keyword splat, and mixed unsupported + destructuring. + +Acceptance: + +- `KeywordHashNode` and simple `ParametersNode` unsupported-output counts fall + near zero. +- Common constructor, diagnostic, and helper calls with keyword args translate + without wrapping the enclosing method in TODO comments. + +Expected impact: + +- Required for >90%. Keyword args are frequent in constructors and diagnostics, + and currently erase useful inner method bodies. + +### 3. Lower Unknown Calls With Literal Blocks + +Audit signal: + +- 9,021 literal blocks attached to calls. +- Top non-Sorbet block callees include `each` (925), `map` (338), `new` (319), + `any?` (126), `each_with_index` (73), `filter_map` (64), `select` (55), + `flat_map` (52), `each_value` (49), `find` (46), `reject` (44), + `each_with_object` (36), `sort_by` (31), `each_pair` (25), `loop` (20), + `map!` (20), `reverse_each` (17), `sum` (16), and `each_key` (15). + +Implementation: + +- Add a real `BlockNode` visitor or block lowering result object so unknown + helper calls with blocks can preserve their bodies. +- Keep existing efficient pipeline translations for expression-only enumerable + blocks. +- Add direct loop-like lowering for `each_with_index`, `each_key`, + `each_value`, `each_pair`, `reverse_each`, `loop`, and simple + multi-statement `each`. +- Support `next` inside known enumerable blocks only where it has a direct CLEAR + equivalent. +- Leave nonlocal `return`, `break`, `yield`, `super`, `rescue`, and `ensure` + localized as TODOs unless the enclosing block shape has an exact lowering. + +Acceptance: + +- Unknown block calls no longer collapse into large unsupported regions. +- Top enumerable block shapes have oracle tests using real source snippets. + +Expected impact: + +- Necessary to move from structural partial output to high useful LoC coverage. + This is also where manual-repair quality improves the most. + +### 4. Complete Method And Declaration Shapes + +Audit signal: + +- `DefNode`: 5,590 total nodes. +- `RequiredParameterNode`: 9,533 total nodes. +- `OptionalKeywordParameterNode`: 470 total nodes. +- `RequiredKeywordParameterNode`: 310 total nodes. +- Top calls include Sorbet-heavy declarations: `sig` (5,686), `params` + (4,376), `returns` (5,045), `const` (1,552), `prop` (267), + `type_alias` (408). + +Implementation: + +- Finish Sorbet erasure/type extraction for the shapes already present. +- Lower `attr_reader`, `attr_writer`, `attr_accessor`, `private`, + `private_class_method`, `include`, and `extend` as declaration metadata or + precise TODOs. +- Improve `T::Struct`, plain `Struct.new`, and constant-record output where + field sets are static. +- Support singleton/class methods where the receiver is statically known. +- Translate Ruby class-like code only into structs plus functions/UFCS when the + data and method set are static. Inheritance, mixins, and interface-like + behavior should remain TODO/refactor targets unless CLEAR already has a direct + construct for the specific case. + +Acceptance: + +- Declaration-only Ruby syntax should rarely contribute unsupported LoC. +- Unsupported declaration semantics are one-line TODOs, not whole-file comments. +- No class/mixin handler introduces hidden OOP semantics. + +Expected impact: + +- Medium to high. This removes syntactic Ruby/Sorbet noise so the remaining + unsupported output represents real semantic work. + +### 5.

The goal is to translate the Ruby subset that maps cleanly to CLEAR +with near-perfect efficiency, and to leave everything else as precise, +localized comments/TODOs that are easy to repair by hand. + +## Non-Goals + +- Do not emulate the Ruby object model in CLEAR. +- Do not add a general runtime compatibility layer for Ruby semantics. +- Do not let the transpiler decide that CLEAR needs namespaces, modules, + traits/interfaces, mixins, inheritance, or other mainstream OOP features. +- Do not translate code when the generated CLEAR would be meaningfully less + direct or less efficient than handwritten CLEAR. +- Do not hide uncertainty behind helpers with Ruby-like behavior. +- Do not treat "more accepted Ruby syntax" as success unless the emitted CLEAR + is mechanically clear, efficient, and reviewable. + +## Language Direction + +CLEAR should lean closer to C/Zig with accessible functional programming than +to Java, Ruby, or other class-heavy OOP languages. The expected target style is +free functions, explicit values, structs, UFCS-style calls, pipelines, and state +where it is useful. A good north star is closer to OCaml with UFCS and explicit +state than to Ruby's object model. + +When Ruby source uses classes, modules, mixins, or interface-by-convention +patterns, the transpiler should first ask whether CLEAR can get by without the +corresponding OOP feature. If the answer is not already clear from existing +CLEAR semantics, emit a localized TODO and treat it as a separate language or +source-refactor decision. + +## Success Criteria + +- Supported constructs emit direct CLEAR with no hidden runtime tax. +- Unsupported constructs preserve the original Ruby source as local comments. +- Mixed constructs preserve all safely translated inner/outer structure. +- The output is deterministic and source-oriented enough for manual repair. +- The audit process identifies the next highest-value handler by observed + source frequency and risk, not by speculation. +- Any new CLEAR language surface proposed by migration is explicitly reviewed + outside the transpiler implementation. + +## Epic 1: Partial Translation Instead Of Whole-Subtree Loss + +Problem: + +The current fallback model is too coarse. If an unsupported inner node appears +inside a partially translatable parent, the parent can collapse into a comment +for the entire source slice.

Today "supported" and "unsupported" are +mostly visitor-presence decisions. + +Direction: + +- Classify translations as exact, mechanical-but-needs-review, or unsupported. +- Require exact/mechanical handlers to state their assumptions in code or tests. +- Make risky handlers fail closed when receiver kind, argument shape, block + shape, or control flow is outside the known subset. +- Prefer explicit TODO markers over helper calls that smuggle Ruby semantics + into CLEAR. + +Acceptance: + +- Registry handlers can reject unsupported receiver/argument/block shapes with + localized TODOs. +- Golden tests cover both accepted and rejected forms for every nontrivial + handler. + +## Epic 3: Context-Aware Method Registry + +Problem: + +`MethodRegistry` is currently keyed mostly by method name.

It should be easy to +review and repair. + +Direction: + +- Preserve file/module structure where practical. +- Preserve comments when Prism locations make that reliable. +- Emit source locations on TODO comments. +- Use stable temporary names and deterministic field ordering. +- Avoid formatting churn unrelated to translation. +- Make generated TODOs searchable by category, for example + `TODO_RUBY_SEND`, `TODO_STDLIB_GAP`, `TODO_BLOCK_CONTROL_FLOW`, and + `TODO_UNTYPED`. + +Acceptance: + +- A developer can jump from each TODO to the original Ruby span. +- Re-running the translator on the same input produces byte-identical output. + +## Epic 10: Equivalence And Golden Testing Process + +Problem: + +The project needs confidence that translated pieces are exact, but it should not +wait for a full self-host before finding divergences. + +Direction: + +- Keep small golden tests for each visitor and registry handler. +- Add corpus fixtures from real compiler files for partial-output behavior. +- Use the Ruby compiler as the oracle for phase outputs when translating larger + compiler slices. +- Compare tokens, AST dumps, semantic indexes, MIR, diagnostics, and emitted + Zig one phase at a time. +- For unsupported regions, assert that the TODO output is precise and stable. + +Acceptance: + +- Every supported translation path has positive and negative fixtures. +- Partial translation tests prove unsupported inner nodes do not erase safe + outer structure. + +## Suggested Implementation Order + +1. Add translation-result objects and localized TODO composition. +2. Convert existing visitors and registry handlers to the result model. +3. Extend `ruby-to-clear-audit` into roadmap mode with + complete/partial/unsupported metrics and ranked next-feature suggestions. +4. Make `MethodRegistry` receiver/context-aware. +5. Add thin stdlib adapter specs for the observed top compiler-hosting calls. +6. Add safe block handlers by audited frequency. +7. Add Sorbet/shape improvements that directly improve emitted CLEAR types. +8.

Add an internal +argument result: + +```ruby +ArgumentList = Struct.new( + :positionals, + :keywords, + :splat, + :keyword_splat, + :forwarding, + keyword_init: true +) +``` + +`positionals` should hold translated expressions in order. `keywords` should +hold ordered `[name, translated_value]` pairs. The visitor should preserve +source order for comments/TODOs, but handler decisions should receive the +structured shape. + +### Safe Call Lowerings + +Ruby: + +```ruby +error!(:type_mismatch, node, expected: expected, actual: actual) +``` + +Target if CLEAR has named arguments: + +```clear +error!(.type_mismatch, node, expected: expected, actual: actual) +``` + +Target if the callee is configured for an options record: + +```clear +error!(.type_mismatch, node, ErrorOptions{ expected: expected, actual: actual }) +``` + +The transpiler should not globally choose between these forms.

The transpiler should emit a TODO unless a handler +declares the exact keyword set. + +Ruby: + +```ruby +send(name, value: x) +``` + +Reason to reject: keyword lowering does not make dynamic dispatch safe. + +### Work Estimate + +This is a medium-sized transpiler change: + +- 2-3 days to add structured argument/parameter objects and retrofit existing + call rendering. +- 1-2 days for Sorbet/declaration keyword adapters. +- 1-2 days for oracle tests and negative fixtures. + +Expected risk is moderate because many existing handlers assume `visit(args)` +returns a string. Convert handlers incrementally, with compatibility helpers +such as `render_arguments(argument_list)`. + +## Block Lowering + +### Current Partial Support + +The registry already supports several expression-only block forms: + +- `map` +- `select` +- `reject` +- `any?` +- `all?` +- `find` / `detect` +- `filter_map` +- `flat_map` +- `sort_by` +- `reduce` / `inject` +- `each` + +The main limitation is `simple_block_expression?`: multi-statement blocks are +rejected even when the final Ruby expression is a direct block result. + +### Required Transpiler Work + +1. Add a structured `BlockLowering` result with parameters, body statements, + final expression, local writes, captured reads, and control-flow flags. +2. Implement implicit return for pipeline blocks: the final expression in a + block is the value of `map`, `select`, `reject`, `flat_map`, `sort_by`, + `sum`, and similar stages. +3. Distinguish side-effect blocks from value blocks. +4. Add a config table for block handlers so each Ruby method declares arity, + result mode, supported control flow, and optional receiver prelude. +5.

The +small prerequisites are: + +- pipeline stages can accept a statement block whose final expression is the + value for value/predicate stages, +- stage composition can insert simple receiver transforms such as `reverse`, + `keys`, `values`, `pairs`, and `withIndex`, +- terminal stages such as `ANY`, `ALL`, `FIND`, and `SUM` can consume those + value/predicate blocks, +- mutable receiver replacement is explicit for `map!`, or `map!` remains a TODO + where aliasing would make replacement incorrect. + +### Implicit Return For Multi-Statement Pipeline Blocks + +Ruby: + +```ruby +nodes.map do |node| + name = node.name.to_s + normalize(name) +end +``` + +Target shape: + +```clear +nodes |> SELECT { + MUTABLE name = node.name.toString(); + normalize(name) +} +``` + +The final expression is the block value. The transpiler should not require a +Ruby `return`, and it should not emit one inside the pipeline block. This needs +one of two CLEAR-side capabilities: + +- pipeline stages accept statement blocks whose last expression is the stage + value, or +- the transpiler can lower the block into a generated local helper function. + +The first option is the minimal compiler/language addition. The second avoids a +pipeline-block language change but creates more generated declarations and +capture plumbing. + +### Safe Block Examples + +Ruby: + +```ruby +items.select do |item| + type = item.type + type != :unknown +end +``` + +Target: + +```clear +items |> WHERE { + MUTABLE type = item.type; + type != .unknown +} +``` + +Ruby: + +```ruby +items.reject do |item| + item.nil? +end +``` + +Target: + +```clear +items |> WHERE !(item == NIL) +``` + +Ruby: + +```ruby +items.reverse_each do |item| + consume(item) +end +``` + +Target: + +```clear +items |> reverse |> EACH { + consume(item); +} +``` + +Ruby: + +```ruby +items.each_with_index do |item, index| + emit(index, item) +end +``` + +Target: + +```clear +items |> withIndex |> EACH { + emit(_.index, _.value); +} +``` + +This requires config support for parameter destructuring or generated names. + +### More Complex But Supportable Blocks + +Ruby: + +```ruby +items.each_with_object(Set.new) do |item, seen| + seen << item.name +end +``` + +Possible target: + +```clear +MUTABLE seen = Set[]; +items |> EACH { + seen.append(item.name); +} +``` + +This is supportable, but it is no longer a pure expression pipeline. The +handler needs to allocate the accumulator before the stage and return it after. + +Ruby: + +```ruby +items.map! do |item| + normalize(item) +end +``` + +Possible target: + +```clear +items = items |> SELECT normalize(item); +``` + +This is safe only when receiver mutation can be represented as replacing the +binding. If aliasing semantics matter, emit a TODO. + +### Unsupported Or TODO Block Cases + +Ruby: + +```ruby +items.map do |item| + return item if item.ready? + item.name +end +``` + +Reason to reject: Ruby `return` exits the enclosing method, not just the block. + +Ruby: + +```ruby +items.each do |item| + break if item.stop? + consume(item) +end +``` + +Reason to reject unless CLEAR pipeline stages support early termination with +matching semantics. + +Ruby: + +```ruby +items.map(&method(:normalize)) +``` + +Reason to reject initially: block arguments require first-class callable shape +tracking. Support only simple `&:to_s`-style symbols if the lowering is direct. + +### Work Estimate + +This is the largest implementation item after keyword args: + +- 2-3 days for `BlockLowering` analysis and implicit return. +- 2-4 days for handler config and core handlers: + `each`, `map`, `select`, `reject`, `flat_map`, `sort_by`, `sum`, `map!`. +- 2-3 days for expanded handlers: + `any?`, `each_with_index`, `each_with_object`, `each_key`, `loop`, + `reverse_each`, `each_value`, `each_pair`. +- 2-3 days for block control-flow detection and negative fixtures. + +The compiler/language work is probably small if pipeline stages can accept +multi-statement blocks with implicit final-expression values. Without that, +the transpiler needs generated helper functions and capture analysis, which is +substantially more invasive. + +## Receiver-Aware Translation And Comptime Decision + +`CallNode` is huge: 89,412 calls and 5,958 unique method names. Most calls are +not currently marked unsupported, but many are likely naive method-call output. +The most concerning Ruby predicates are `is_a?` and `respond_to?`. + +### Preferred Path + +After proper transpilation, most `is_a?` and `respond_to?` calls should +disappear because the source shape has become explicit: + +- tagged unions or enums for closed variants, +- explicit optional values instead of runtime nil/type checks, +- generated field access for static records, +- closed dispatch tables for formerly dynamic method sets, +- source refactors where Ruby was probing object capabilities dynamically. + +### Zig Comptime Option + +It is possible to support some of this with Zig comptime-backed CLEAR helpers, +and that may be the right fallback for hosting/compiler code. Example intent: + +```clear +hasField?(T, "name") +isVariant?(value, .FunctionDef) +hasMethod?(T, "emit") +``` + +This should be treated as a separate design decision, not an automatic Ruby +compatibility layer. + +### When To Use Comptime + +Use comptime/metaprogramming only when all of these are true: + +- the receiver type is statically known, +- the queried member/type is a literal symbol/string/constant, +- the result can compile away, +- the helper expresses a CLEAR concept, not a Ruby object-model behavior. + +### When To Reject + +Ruby: + +```ruby +node.respond_to?(method_name) +node.is_a?(klass) +``` + +Reject when the queried name/type is dynamic. The correct repair is usually a +closed enum/union/table or a source refactor. + +## Block Control Flow And Nonlocal Flow + +Audit signal inside blocks: + +| node | count | +| --- | ---: | +| `NextNode` | 697 | +| `ReturnNode` | 67 | +| `BreakNode` | 44 | +| `SuperNode` | 35 | +| `RescueModifierNode` | 31 | +| `ForwardingSuperNode` | 20 | +| `YieldNode` | 14 | +| `EnsureNode` | 4 | +| `RescueNode` | 3 | + +### Supportable Cases + +Ruby: + +```ruby +items.filter_map do |item| + next if item.skip? + item.value +end +``` + +Target if the handler supports `next` as nil for `filter_map`: + +```clear +items |> SELECT { + IF item.skip?() THEN + NIL + ELSE + item.value + END +} |> WHERE _ != NIL +``` + +Ruby: + +```ruby +items.each do |item| + next if item.skip? + consume(item) +end +``` + +Target: + +```clear +items |> EACH { + IF !(item.skip?()) THEN + consume(item); + END +} +``` + +Ruby: + +```ruby +loop do + token = next_token + break if token.nil? + consume(token) +end +``` + +Target if CLEAR has a direct loop/break shape: + +```clear +WHILE TRUE DO + MUTABLE token = nextToken(); + IF token == NIL THEN + BREAK; + END + consume(token); +END +``` + +### Unsupported Cases + +Ruby: + +```ruby +items.map do |item| + return item if item.ready? + item.value +end +``` + +Reject: `return` exits the enclosing Ruby method. Translating it inside a +pipeline stage would be wrong unless CLEAR gets explicit nonlocal return +semantics, which is not desirable for this migration path. + +Ruby: + +```ruby +items.each do |item| + super(item) +end +``` + +Reject: `super` and forwarding `super` require class/inheritance semantics. + +Ruby: + +```ruby +items.map do |item| + risky(item) rescue fallback +end +``` + +Reject until CLEAR exception/error handling shape is explicit for this source +region.

Expand Enumerable Pipeline Handlers + +Status: expression and some multi-statement forms are supported. + +Work: + +- Ensure these handlers support single-expression and multi-statement blocks: + `map`, `map!`, `select`, `reject`, `filter_map`, `flat_map`, `sort_by`, + `sum`, `find`, `any?`, `all?`, and simple `reduce`. +- Add handler-local rewrites for receiver transforms: + - `reverse_each { ... }` -> `receiver.reverse() |> EACH { ... }` + - `each_key { |k| ... }` -> `receiver.keys() |> EACH { ... }` + - `each_value { |v| ... }` -> `receiver.values() |> EACH { ... }` + - `each_pair { |k, v| ... }` -> TODO until tuple/pair binding shape is + explicit. +- For `each`, emit side-effect `EACH { ... }` and allow statement-only block + bodies. +- For value-producing stages, reject blocks whose final statement is not a + usable expression. + +Acceptance: + +- Add oracle tests for happy-path and sad-path Ruby snippets for each handler. +- Add CLEAR compile smoke tests for generated pipeline output. +- The audit tool reports lower block TODO counts for top callees without + increasing broad unsupported regions. + +Why this is now unlocked: + +- `map`/`select`/`sort_by` no longer have to collapse when the block needs a + temporary local before the final value. + +### 3. Normalize Fallible Stdlib Mapping Around `pkg:fs` + +Status: `File.read`, `File.readlines`, `File.foreach`, `File.write`, +`File.binwrite`, and `File.size` can emit `REQUIRE "pkg:fs"` and `OR RAISE`. + +Work: + +- Move remaining fs-like mappings from legacy helper names to package calls + once the CLEAR stdlib name is approved: + - `File.exist?`, `File.exists?` + - `File.file?` + - `File.directory?` / `Dir.exist?` + - `File.delete` + - `File.mtime` + - `File.readlink` + - `File.symlink` + - `File.symlink?` +- Keep path-only transforms separate if they belong in `pkg:path`: + - `File.join` + - `File.expand_path` + - `File.basename` + - `File.dirname` + - `Dir.glob` +- Mark only genuinely fallible functions as `RETURNS !T`. +- Wrap fallible pipeline sources in parentheses before adding pipeline stages. + +Acceptance: + +- Every fallible fs mapping emits one `REQUIRE "pkg:fs"` and marks the enclosing + function fallible. +- Nonfallible predicates and pure path helpers do not force `!T`. +- The gem has paired tests for top-level expression output and function-body + fallibility. + +Why this is now unlocked: + +- The package-require/fallibility path exists, so stdlib mappings no longer + need placeholder helper names that hide error behavior. + +### 4.

CLEAR should expose Ruby/Elixir-level ergonomics by + default and expose systems-level detail only when that detail is needed + for correctness, performance, or capability control. + + We deviate from high-level interfaces for major flaws: + + - hidden unbounded memory growth in common usage; + - impossible or misleading resource lifetime semantics; + - data races or capability violations; + - effect/capability behavior that the compiler cannot track; + - performance cliffs that are large, common, and hard to diagnose; + - APIs that make deterministic compiler output unreliable; + - APIs that prevent a lower-level zero-cost path from existing. + + Ordinary systems-language preference is not enough by itself. "Zig would + make the allocator explicit" or "Java would force a stream object" may be + true, but those are not automatically good CLEAR user interfaces. + + ## IO And Streams + + File and network IO are the test case. CLEAR should not make ordinary IO + as hard as Java or Zig. + + ```ruby clear illustrative + text = fs.read("config.clear") OR RAISE; + lines = fs.readLines("users.txt") OR RAISE; + fs.write("out.txt", report) OR RAISE; + ``` + + Pipelines should default to using streams internally where that is the + efficient strategy, especially for IO and large inputs. A pipeline can be + collected implicitly by its destination type, or explicitly with a + terminal such as `COLLECT_LIST`, `COLLECT_SET`, `COLLECT_MAP`, or + `AS_STREAM`. + + ```ruby clear illustrative + users = (fs.readLines("users.csv") OR RAISE) + |> MAP { parseUser(_) } + |> SELECT { _.active?() }; + ``` + + The implementation may stream `users.csv` line by line. Because the + assignment target is a list, the final value collects into that list. + + Users who want a stream, map, set, or another collection request it + explicitly: + + ```ruby clear illustrative + active_stream = (fs.readLines("users.csv") OR RAISE) + |> MAP { parseUser(_) } + |> SELECT { _.active?() } + |> AS_STREAM; + + users_by_id = (fs.readLines("users.csv") OR RAISE) + |> MAP { parseUser(_) } + |> COLLECT_MAP { _.id => _ }; + + unique_domains = (fs.readLines("emails.txt") OR RAISE) + |> MAP { domainOf(_) } + |> COLLECT_SET; + ``` + + The exact names are not final. The principle is final: stream internally + where practical, collect from the explicit terminal or destination type, + and never insert hidden sorts or other semantic work during collection. + + Ordering is explicit. Directory scans and globbing should be unsorted + streams unless the user asks otherwise: + + ```ruby clear illustrative + files = fs.glob("src/**/*.cht") OR RAISE; + sorted = files |> ORDER_BY _; + ``` + + A future `SORT` shorthand may sort by the singular value, but that + depends on the traits/interfaces or duck-typed ordering decision. Today + `ORDER_BY` is the explicit sortable pipeline operator. + + ## Key Decisions Before Self-Host Implementation + + 1. Confirm pipeline result defaults: stream internally where practical; + collect according to explicit terminal or destination type. + 2. Choose explicit collection target syntax: `AS_STREAM`, `COLLECT_LIST`, + `COLLECT_MAP`, `COLLECT_SET`, and typed collection targets. + 3. Define the named error taxonomy and future `Result` relationship; + prototype stdlib APIs use native `!T` fallibility and `OR` + propagation. + 4. Decide which effects are public stdlib contracts for self-host + packages: file read/write, process/env, network read/write, time, + random, allocation, blocking, and extern. + 5. Decide package capability permissions for files, network, processes, + environment, clocks, and randomness. + 6. Decide resource lifetime and stream lifetime rules. + 7. Decide the stateless/stateful naming convention. + 8. Decide the string/bytes split and deterministic ordering defaults. + MD + page("stdlib/collections.md", <<~MD), + # Collections And Pipelines + + #{WARNING} + + Status: `planned`, `self-host required`. + + Collections should feel like Ruby and Elixir at the call site while still + giving the compiler enough information to track allocation, mutation, + ownership, effects, and capability use. + + ## Planned Types + + | Type | Status | Notes | + | --- | --- | --- | + | Slice | `prototype` | Borrowed view over contiguous values. | + | List/vector | `intrinsic today` | Growable contiguous collection. | + | Map/hash | `intrinsic today` | Hash map; deterministic views required for compiler output. | + | Set | `intrinsic today` | Hash set; deterministic views required for compiler output. | + | Range | `prototype` | Numeric iteration and slicing. | + | Pool/slab | `intrinsic today` | Stable handles for compiler/runtime structures. | + | Queue/deque | `planned` | Add when compiler or scheduler code needs it. | + + ## Planned Transforms + + | API | Status | Behavior | + | --- | --- | --- | + | `each` | `self-host required` | Side-effect iteration, returns `Void`. | + | `map` | `self-host required` | New list from final block expression. | + | `select` / `filter` | `self-host required` | Keeps values where predicate is true. | + | `reject` | `self-host required` | Inverse filter. | + | `filterMap` | `self-host required` | Maps to `?T`, keeps non-nil values. | + | `flatMap` | `self-host required` | Maps to collections and flattens. | + | `reduce` / `fold` | `self-host required` | Explicit accumulator. | + | `any?`, `all?` | `self-host required` | Short-circuit predicates. | + | `find` | `self-host required` | Returns `?T`. | + | `sum`, `count` | `self-host required` | Numeric and predicate aggregation. | + | `ORDER_BY` | `self-host required` | Explicit sort by key expression. | + | `keys`, `values`, `pairs` | `self-host required` | Map traversal; explicit ordered variants where output order matters. | + | `indexed` | `self-host required` | Replacement for Ruby `each_with_index`. | + | `withObject` / `foldInto` | `self-host required` | Replacement for Ruby `each_with_object`. | + + ## Pipeline Result Defaults + + Pipelines may stream internally, but collection is determined by explicit + terminal or destination type.
