Content

Rule kinds in the Content family. Each rule below links to its own page with options, an example, and any auto-fix support.

Rule	Description
`file_content_matches`	File contents must contain at least one match for a regex.
`file_content_forbidden`	File contents must NOT match a regex.
`file_header`	The first N lines must match a regex (line-oriented).
`file_starts_with`	Byte-level prefix / suffix check.
`file_ends_with`	Byte-level prefix / suffix check.
`file_hash`	Content SHA-256 must equal the expected digest.
`file_max_size`	File must be at most `max_bytes` in size.
`file_min_size`	File must be at least `min_bytes` in size.
`file_min_lines`	File must have at least `min_lines` lines (`\n`-terminated, with an unterminated trailing segment counting as one more, `wc -l` semantics).
`file_max_lines`	File must have at most `max_lines` lines, using the same accounting as `file_min_lines`.
`file_footer`	The configured number of final lines in each file in scope must match a regex.
`file_shebang`	First line of each file in scope must match the `shebang` regex.
`file_is_text`	Content is detected as text (magic bytes + UTF-8 validity check), fails on binary files matched by `paths`.
`file_is_ascii`	Every byte in the file must be < 0x80 (pure ASCII), except codepoints listed in `allow:`.
`editorconfig_conforms`	Enforce selected formatting properties from the repository's own `.editorconfig` files without repeating those values in `.alint.yml`.
`pinned_references`	Require executable references in supported CI and container files to identify immutable artifacts rather than mutable tags or branches.
`markdown_images_have_alt`	Require every live CommonMark image to have non-empty rendered alt text.
`markdown_required_headings`	Require the complete rendered heading sequence to match an ordered `headings` template.
`markdown_no_duplicate_headings`	Reject a later Markdown heading whose generated base anchor collides with an earlier heading.
`spdx_identifier_valid`	Validate every `SPDX-License-Identifier:` value as a strict SPDX license expression.
`executable_has_shebang`	Every file with `+x` set must begin with `#!`.
`shebang_has_executable`	Every file starting with `#!` must have `+x` set.
`commented_out_code`	Heuristic detector for blocks of commented-out source code (as opposed to prose comments, license headers, doc comments, or ASCII banners).
`markdown_links_resolve`	Validate live Markdown link, image, and reference-definition destinations against the repository tree.
`markdown_fragments_resolve`	Require every live local Markdown link fragment to name a heading anchor in its resolved target document.
