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, HTML asset reference extraction, and incremental caching of parse results.

Re-exports

pub use astro::extract_astro_frontmatter;

Modules

astro

Astro component frontmatter extraction.

cache

Incremental parse cache with bitcode serialization.

css

CSS/SCSS file parsing and CSS Module class name extraction.

html

HTML file parsing for script, stylesheet, and Angular template references.

mdx

MDX import/export statement extraction.

sfc

Vue/Svelte Single File Component (SFC) script extraction.

suppress

Inline suppression comment parsing.

visitor

Oxc AST visitor for extracting imports, exports, re-exports, and member accesses.

Structs

DynamicImportInfo

A dynamic import() call.

DynamicImportPattern

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

ExportInfo

An export declaration.

ImportInfo

An import declaration.

MemberAccess

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

MemberInfo

A member of an enum, class, or namespace.

ModuleInfo

Extracted module information from a single file.

ParseResult

Result of parsing all files, including incremental cache statistics.

ReExportInfo

A re-export declaration.

RequireCallInfo

A require() call.

Enums

ExportName

Export identifier.

ImportedName

How a symbol is imported.

MemberKind

The kind of member.

Constants

ANGULAR_TPL_SENTINEL

Sentinel value used as the object field in MemberAccess entries produced by the Angular template scanner. The analysis phase checks imports for entries with this sentinel and merges them into the component’s self_accessed_members set.

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.

parse_from_content

Parse from in-memory content (for LSP, includes complexity).

parse_single_file

Parse a single file and extract module information (without complexity).
