Crate fallow_extract 

Parsing and extraction engine for the fallow codebase analyzer.

This crate handles all file parsing: JS/TS via Oxc, Vue/Svelte SFC extraction, Astro frontmatter, MDX import/export extraction, CSS Module class name extraction, and incremental caching of parse results.

DynamicImportPattern

A dynamic import with a pattern that can be partially resolved (e.g., template literals).

ExportInfo

An export declaration.

ImportInfo

MemberAccess

A static member access expression (e.g., Status.Active, MyClass.create()).

MemberInfo

A member of an enum or class.

ModuleInfo

Extracted module information from a single file.

ParseResult

Result of parsing all files, including incremental cache statistics.

Functions

compute_line_offsets

Compute a table of line-start byte offsets from source text.

parse_all_files

Parse all files in parallel, extracting imports and exports. Uses the cache to skip reparsing files whose content hasn’t changed.
