pine-tools

Unofficial Pine Script v6 tooling: a VS Code extension, a pine-lint CLI, an LSP server, and an MCP server, plus the generated language data behind them.

The linter aims to be MORE correct than TradingView's own pine-lint: it catches what TV catches and things TV misses (TV stops at the first error, misattributes some failures, and accepts some nonsense expressions). See AGENTS.md for the methodology. Built with LLMs in a clean-room process; see LLM.md.

What you get

• VS Code extension: syntax highlighting, IntelliSense (475 functions, 162 variables, 237 constants), real-time diagnostics, hover docs, go-to-definition, rename, formatting, and inlay hints.
• pine-lint: a self-contained CLI that validates a .pine file (or stdin), with an optional --tv mode that returns TradingView's own verdict.
• LSP server: the same language features for any editor that speaks LSP.
• MCP server: the language service exposed to AI assistants.

Install

Grab the prebuilt artifacts from the latest release:

• pine-tools-<version>.vsix - the VS Code extension. Install with code --install-extension pine-tools-<version>.vsix, or the Extensions view's "Install from VSIX...".
• pine-lint - a single executable Node script. Put it on your PATH and run pine-lint file.pine.

Or build from source (Node 22.18+, pnpm):

pnpm install
pnpm run package         # build dist/pine-tools-<version>.vsix
pnpm run install:cli     # build and install pine-lint to ~/.local/bin

Acknowledgements

vendor/ contains the source of published Pine Script libraries, used only to derive each library's exported-symbol set (pine-data/v6/libraries.json) so the linter can validate imported-library member calls (flagging calls to functions a library does not export). Each file retains its original license header.

All vendored libraries are licensed under the Mozilla Public License 2.0 (https://mozilla.org/MPL/2.0/) by their respective authors. Libraries published under non-redistributable or unstated terms are deliberately not vendored; the linter stays lenient on those imports.

TradingView's own ta and RelativeValue libraries are TradingView's pure-Pine reference implementations. The community libraries are the work of, in alphabetical order: algotraderdev, andre_007, Bjorgum, boitoki, DevLucem, HeWhoMustNotBeNamed, HoanGhetti, HPotter, jason5480, jdehorty, jmosullivan, kaigouthro, LonesomeTheBlue, loxx, LucF, LudoGH68, PineCoders, reees, RicardoSantos, robbatt, TFlab, toodegrees, Trendoscope, and ZenAndTheArtOfTrading.
