The system transforms individual RSCG projects into structured documentation with code examples and cross-referenced content with a searchable website and code example exports.
The RSCG_Examples repository is a comprehensive documentation system that automatically processes and showcases 286 Roslyn Source Code Generator (RSCG) examples. The system transforms individual RSCG projects into structured documentation with code examples and cross-referenced content with a searchable website and code example exports.

This system serves as both a learning resource for .NET developers interested in source generators and an automated pipeline for maintaining up-to-date documentation about the RSCG ecosystem

Microsoft CodeTour schema pattern property regular expression step file

💡 Result:

In the Microsoft CodeTour JSON schema, the pattern property is used to associate a tour step with specific content in a file using a regular expression [1][2][3]. Key details regarding the pattern property include: Usage: It allows you to define a regular expression string that CodeTour uses to locate the associated step within a file [1][4]. Relationship with 'line': The pattern property is only evaluated if the line property is not set for that step [1][5]. This provides a more resilient way to associate steps with code, as it avoids reliance on fixed ordinal line numbers which may change as code is edited [6][7]. Implementation: When the extension navigates to a step containing a pattern, it searches the associated file for a match to the provided regular expression [1][3]. To ensure your.tour files are valid and benefit from schema validation (including auto-completion), it is recommended to include the $schema property at the top of your file [8]: { "$schema": "https://aka.ms/codetour-schema",... } For further verification of the schema structure, you can refer to the authoritative JSON schema file at https://aka.ms/codetour-schema [9][10].

Replace the placeholder tour patterns.

"this is the code" does not occur in either referenced source file, so CodeTour cannot anchor these steps. Use QuickStartRepoStub for TestClock.cs and interface IMyClock for IMyClock.cs.

In `@v2/.tours/SatorImaging.TDoubles.tour` at line 16, Replace the placeholder
pattern in the tour configuration with the correct source anchors: use
QuickStartRepoStub for the TestClock.cs step and interface IMyClock for the
IMyClock.cs step, ensuring each tour step can locate its referenced code.

Add a build prerequisite for the three generated-source steps.

The steps reference untracked files under src/TestClock/obj/GX, which the project emits only during compilation. A clean checkout does not contain these files. Add an explicit build prerequisite or track generated-source snapshots.

In `@v2/.tours/SatorImaging.TDoubles.tour` at line 27, Add an explicit build
prerequisite before the three generated-source steps in the
SatorImaging.TDoubles tour so the files under src/TestClock/obj/GX are produced
before they are referenced. Ensure clean checkouts execute the required project
build first, or alternatively track generated-source snapshots if that is the
established project convention.
