Workflow
Standard Lint-Fix-Verify Cycle
- Run lint check:
markdownlint-cli2 "**/*.md" - Review reported issues
- Apply auto-fix:
markdownlint-cli2 --fix "**/*.md" - Re-run lint to verify:
markdownlint-cli2 "**/*.md" - Review changes:
git diff - Commit when satisfied
Safe Fix with Backup
- Stage current state:
git add . - Create backup commit:
git commit -m "Backup before markdownlint fix" - Apply fixes:
markdownlint-cli2 --fix "**/*.md" - Review changes:
git diff - Commit fixes or reset:
git add . && git commit -m "Apply markdownlint fixes"
Cross-Platform Usage
For maximum compatibility:
- Quote glob patterns:
markdownlint-cli2 "**/*.md" - Use
#for negation:markdownlint-cli2 "**/*.md" "#vendor"(not!) - Use forward slashes:
docs/**/*.md(works on all platforms) - Stop option processing:
markdownlint-cli2 -- "special-file.md"
Troubleshooting
No Files Matched
- Verify glob patterns are quoted
- Check file extensions (
.mdvs.markdown) - Ensure negated patterns don't exclude everything
Too Many Issues
- Start with auto-fix:
markdownlint-cli2 --fix "**/*.md" - Disable problematic rules temporarily
- Address remaining issues incrementally
Configuration Not Loading
- Verify configuration file name matches expected patterns
- Validate JSON/YAML syntax
- Use
--configto explicitly specify the file
