I've been trying out LLM agents for compiler development, and one thing
i found is that the agent naturally wants to run `yarn snap <pattern>`
to test a specific fixture, and I want to be able to tell it (directly
or in rules/skills) to do this in order to get the debug output from all
the compiler passes. Agents can figure out our current testfilter.txt
file system but that's just tedious. So here we add support for `yarn
snap -p <pattern>`. If you pass in a pattern with an extension, we
target that extension specifically. If you pass in a .expect.md file, we
look at that specific fixture. And if the pattern doesn't have
extensions, we search for `<pattern>{.js,.jsx,.ts,.tsx}`. When patterns
are enabled we automatically log as in debug mode (if there is a single
match), and disable watch mode.
Open to feedback!
React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
