…S env var Users can now specify additional file extensions to index without editing source code, e.g. COCOINDEX_CODE_EXTRA_EXTENSIONS="inc,tpl"
Allow `ext:lang` format (e.g. "inc:php,yaml,tpl:html") to override language detection for extra extensions, enabling proper AST-based chunking for unrecognized extensions.

Background
Some legacy PHP projects use
.incas a file extension, but it is currently not indexed and therefore excluded from code search.Changes
Users can now specify additional file extensions to index via the
COCOINDEX_CODE_EXTRA_EXTENSIONSenvironment variable.COCOINDEX_CODE_EXTRA_EXTENSIONS="inc,tpl"Language detection is handled by the
detect_code_languagefunction in cocoindex, but some extensions like.incare not tied to a specific language. To handle this, users can now specify the language explicitly using theext:langformat to override detection.COCOINDEX_CODE_EXTRA_EXTENSIONS="inc:php,yaml,tpl:html"When no language is specified, it falls back to
detect_code_languageas before.Note
Language mapping is currently handled on the caller side. If there is a better place for this (e.g. extending
detect_code_language), I'm happy to adjust the approach.Tests
All 20 tests pass
