Source Map Sharp

About

This is a direct rewrite (meaning, the goal was not to write 'idiomatic' F# code, but to resemble inital JS code as close as possible) of source map generation tool https://github.com/mozilla/source-map

Which is originally written in JS. The initial purpose is to use it with https://github.com/fable-compiler/Fable project

See https://github.com/fable-compiler/Fable/issues/2166 - "Bring back source map support"

UPD: The issue above was closed, and this project is now being used by Fable to generated Source Maps. Hooray!

Current support status

• Fable - working fine
• .NET - working fine

Running tests

dotnet:

dotnet test

Fable (js):

dotnet tool restore
pnpm install
pnpm test

Files - status

1. SourceNode fromStringWithSourceMap function
2. SourceMapGenerator fromSourceMap function
3. SourceMapConsumer module
4. SourceMapNode, SourceMapGenerator - consumer-related tests

Help needed

1. Source map consumer
2. Documentation & usage examples
