no_merge_conflict_markers

Flag <<<<<<< , =======, >>>>>>> , ||||||| markers at the start of a line — almost always left over from an unresolved merge. The anchor markers carry a trailing ref (<<<<<<< HEAD), so they never collide with prose; a bare ======= is reported only when the file also contains one of those anchors, because on its own a seven-character ======= is indistinguishable from a reST/Markdown setext heading underline (so docs trees no longer need to be excluded).

Options

This rule takes no kind-specific options.

Plus the common paths, level, id, and when fields. This table is generated from the JSON Schema; option types and defaults are authoritative.

Example

A source file with unresolved merge conflict markers

The rule fires on this repository:

src/
src/clean.rs
src/half_merged.rs

src/clean.rs

pub fn ok() {}

src/half_merged.rs

<<<<<<< HEAD
ours
=======
theirs
>>>>>>> feature

With this .alint.yml:

version: 1
rules:
  - id: no-conflict
    kind: no_merge_conflict_markers
    paths: "src/**/*"
    level: error

alint check reports:

--- src/half_merged.rs ---------------------------------------------------------
  x  error    no-conflict
              1:1  unresolved merge conflict marker on line 1: "<<<<<<<"

Summary (1 violation):
  x 1 error
  0 passing * 1 failing

Source files with no leftover conflict markers

This repository is compliant:

src/
src/a.rs
src/docs.md

src/a.rs

pub fn a() {}

src/docs.md

Conflict discussion: we use <<<<<< for ... (inline, no col-1 marker)
