  "message": "Expand Crubit live-snippets on crubit.rs with an mdBook preprocessor.\n\nPreviously, Copybara rewrote each g3doc `live-snippet` into an mdBook\n`{{#include}}` of the whole file, dropping the Code Search query (e.g.\n`function:clamp_value`) into an HTML comment. On crubit.rs, every snippet\ntherefore showed the entire file, including the license header, and\nsnippets nested in lists or outside `g3doc/*/*.md` did not work at all.\n\nThis adds `tools/mdbook_live_snippet`, a small mdBook preprocessor that\nexpands `live-snippet` blocks itself, approximating g3doc semantics:\n\n* no query: the whole file, minus the license header;\n* `content:\u003cregex\u003e`: the lines touched by matches (with `.` matching\n  newlines, as Crubit docs already assume);\n* `function:`, `class:`, `symbol:`: the matching definitions, including\n  leading comments and attributes, found with a lightweight lexer for\n  C++ and Rust, and by target name for BUILD files.\n\nSnippets keep their indentation, and any snippet that fails to resolve\nfails the docs build instead of silently rendering the wrong code.\n\nCopybara now only rewrites snippet paths to be repository-relative, and\nbook.toml builds and runs the preprocessor with Cargo.\n\nPiperOrigin-RevId: 1005273630\n",
