# CI lint: flags a contiguous comment block longer than MAX lines. A giant
|
|
# prose block in source is a signal it should live in docs/ as an
|
|
# "implementation notes" section instead — short "why"/invariant/contract
|
|
# comments stay, walls of text move out. See the hive convention in #2077.
|
|
#
|
|
# Emits a CI error annotation per offending block and exits 1 if any block
|
|
# exceeds MAX. Runs as its own CI job and IS a required check on the forge
|
|
# (branch protection) — a hit blocks merge.
|
|
#
|
|
# Scope: tracked *.rs *.nix *.sh *.js *.ts *.css *.html. Markdown is exempt
|
|
# (it is prose by nature). Comment forms: `#` line comments (nix/sh), `//`
|
|
# line comments (rs/js/ts), and `/* */` block comments (nix/rs/js/ts/css) +
|
|
# `<!-- -->` (html). A blank line separates two line-comment blocks (does NOT
|
|
# extend a run); a blank inside a `/* */` / `<!-- -->` block stays part of it.
|
|
#
|
|
# Escape hatch: a `lint:allow-long-comment` marker anywhere in a block
|
|
# exempts it (reserve for a genuinely irreducible block; prefer relocating).
