Usage

Getting started with rumdl is simple:

# Lint a single file
rumdl check README.md

# Lint all Markdown files in current directory and subdirectories
rumdl check .

# Format a specific file
rumdl fmt README.md

# Create a default configuration file
rumdl init

Common usage examples:

# Lint with custom configuration
rumdl check --config my-config.toml docs/

# Disable specific rules
rumdl check --disable MD013,MD033 README.md

# Enable only specific rules
rumdl check --enable MD001,MD003 README.md

# Exclude specific files/directories
rumdl check --exclude "node_modules,dist" .

# Include only specific files/directories
rumdl check --include "docs/*.md,README.md" .

# Watch mode for continuous linting
rumdl check --watch docs/

# Combine include and exclude patterns
rumdl check --include "docs/**/*.md" --exclude "docs/temp,docs/drafts" .

# Don't respect gitignore files (note: --respect-gitignore defaults to true)
rumdl check --respect-gitignore=false .

# Force exclude patterns even for explicitly specified files (useful for pre-commit)
rumdl check excluded.md --force-exclude  # Will respect exclude patterns in config

Stdin/Stdout Formatting

rumdl supports formatting via stdin/stdout, making it ideal for editor integrations and CI pipelines:

# Format content from stdin and output to stdout
cat README.md | rumdl fmt - > README_formatted.md
# Alternative: cat README.md | rumdl fmt --stdin > README_formatted.md

# Use in a pipeline
echo "# Title   " | rumdl fmt -
# Output: # Title

# Format clipboard content (macOS example)
pbpaste | rumdl fmt - | pbcopy

# Provide filename context for better error messages (useful for editor integrations)
cat README.md | rumdl check - --stdin-filename README.md

Editor Integration

For editor integration, use stdin/stdout mode with the --quiet flag to suppress diagnostic messages:

# Format selection in editor (example for vim)
:'<,'>!rumdl fmt - --quiet

# Format entire buffer
:%!rumdl fmt - --quiet

Pre-commit Integration

You can use rumdl as a pre-commit hook to check and format your Markdown files.

The recommended way is to use the official pre-commit hook repository:

rumdl-pre-commit repository

Add the following to your .pre-commit-config.yaml:

repos:
  - repo: https://github.com/rvben/rumdl-pre-commit
    rev: v0.0.196
    hooks:
      - id: rumdl      # Lint only (fails on issues)
      - id: rumdl-fmt  # Auto-format (fixes what it can)

Two hooks are available:

• rumdl — Lints files and fails if any issues are found (ideal for CI)
• rumdl-fmt — Auto-formats files (fixes what it can, always succeeds)

When you run pre-commit install or pre-commit run, pre-commit will automatically install rumdl in an isolated Python environment using pip. You do not need to install rumdl manually.

Excluding Files in Pre-commit

By default, when pre-commit passes files explicitly to rumdl, the exclude patterns in your .rumdl.toml configuration file are ignored. This is intentional behavior - if you explicitly specify a file, it gets checked.

However, for pre-commit workflows where you want to exclude certain files even when they're passed explicitly, you have two options:

1. Use force_exclude in your configuration file:

   # .rumdl.toml
   [global]
   exclude = ["generated/*.md", "vendor/**"]
   force_exclude = true  # Enforce excludes even for explicitly provided files
   

2. Use the --force-exclude flag in your pre-commit config:

   repos:
     - repo: https://github.com/rvben/rumdl-pre-commit
       rev: v0.0.196
       hooks:
         - id: rumdl
           args: [--force-exclude]  # Respect exclude patterns from config
   

CI/CD Integration

GitHub Actions

We have a companion Action you can use to integrate rumdl directly in your workflow:

jobs:
  rumdl-check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v6
      - uses: rvben/rumdl@v0

The v0 tag always points to the latest stable release, following GitHub Actions conventions.

Inputs

Input	Description	Default
version	Version of rumdl to install	latest
path	Path to lint	workspace root
config	Path to config file	auto-detected
report-type	Output format: logs or annotations	logs

Examples

Lint specific directory with pinned version:

- uses: rvben/rumdl@v0
  with:
    version: "0.0.189"
    path: docs/

Use custom config and show annotations in PR:

- uses: rvben/rumdl@v0
  with:
    config: .rumdl.toml
    report-type: annotations

The annotations report type displays issues directly in the PR's "Files changed" tab with error/warning severity levels and precise locations.

Rules

rumdl implements 54 lint rules for Markdown files. Here are some key rule categories:

Category	Description	Example Rules
Headings	Proper heading structure and formatting	MD001, MD002, MD003
Lists	Consistent list formatting and structure	MD004, MD005, MD007
Whitespace	Proper spacing and line length	MD009, MD010, MD012
Code	Code block formatting and language tags	MD040, MD046, MD048
Links	Proper link and reference formatting	MD034, MD039, MD042
Images	Image alt text and references	MD045, MD052
Style	Consistent style across document	MD031, MD032, MD035

For a complete list of rules and their descriptions, see our documentation or run:

Configuration

rumdl can be configured in several ways:

1. Using a .rumdl.toml or rumdl.toml file in your project directory or parent directories
2. Using a .config/rumdl.toml file (following the config-dir convention)
3. Using the [tool.rumdl] section in your project's pyproject.toml file (for Python projects)
4. Using command-line arguments
5. Automatic markdownlint compatibility: rumdl automatically discovers and loads existing markdownlint config files (.markdownlint.json, .markdownlint.yaml, etc.)

Configuration Discovery

rumdl automatically searches for configuration files by traversing up the directory tree from the current working directory, similar to tools like git , ruff , and eslint . This means you can run rumdl from any subdirectory of your project and it will find the configuration file at the project root.

The search follows these rules:

• Searches upward for .rumdl.toml, rumdl.toml, .config/rumdl.toml, or pyproject.toml (with [tool.rumdl] section)
• Precedence order: .rumdl.toml > rumdl.toml > .config/rumdl.toml > pyproject.toml
• Stops at the first configuration file found
• Stops searching when it encounters a .git directory (project boundary)
• Maximum traversal depth of 100 directories
• Falls back to markdownlint config files (.markdownlint.yaml, etc.) using the same upward traversal
• Falls back to user configuration if no project configuration is found (see Global Configuration below)

To disable all configuration discovery and use only built-in defaults, use the --isolated flag:

# Use discovered configuration (default behavior)
rumdl check .

# Ignore all configuration files
rumdl check --isolated .

Editor Support (JSON Schema)

rumdl provides a JSON Schema for .rumdl.toml configuration files, enabling autocomplete, validation, and inline documentation in supported editors like VS Code, IntelliJ IDEA, and others.

The schema is available at https://raw.githubusercontent.com/rvben/rumdl/main/rumdl.schema.json.

VS Code Setup:

1. Install the "Even Better TOML" extension
2. The schema will be automatically associated with .rumdl.toml and rumdl.toml files once submitted to SchemaStore

Manual Schema Association:

Add this to your .rumdl.toml file (in a comment, as TOML doesn't support $schema):

# yaml-language-server: $schema=https://raw.githubusercontent.com/rvben/rumdl/main/rumdl.schema.json

This enables IntelliSense, validation, and hover documentation for all configuration options.

Global Configuration

When no project configuration is found, rumdl will check for a user-level configuration file in your platform's standard config directory:

Location:

• Linux/macOS: ~/.config/rumdl/ (respects XDG_CONFIG_HOME if set)
• Windows: %APPDATA%\rumdl\

Files checked (in order):

1. .rumdl.toml
2. rumdl.toml
3. pyproject.toml (must contain [tool.rumdl] section)

This allows you to set personal preferences that apply to all projects without local configuration.

Example: Create ~/.config/rumdl/rumdl.toml:

[global]
line-length = 100
disable = ["MD013", "MD041"]

[MD007]
indent = 2

Note: User configuration is only used when no project configuration exists. Project configurations always take precedence.

Markdownlint Migration

rumdl provides seamless compatibility with existing markdownlint configurations:

Automatic Discovery: rumdl automatically detects and loads markdownlint config files by traversing up the directory tree (just like .rumdl.toml):

• .markdownlint.json / .markdownlint.jsonc
• .markdownlint.yaml / .markdownlint.yml
• markdownlint.json / markdownlint.yaml

This means you can place a .markdownlint.yaml at your project root and run rumdl from any subdirectory - it will find and use the config automatically.

** Explicit Import**: Convert markdownlint configs to rumdl format:

# Convert to .rumdl.toml
rumdl import .markdownlint.json

# Convert to JSON format
rumdl import --format json .markdownlint.yaml --output config.json

# Preview conversion
rumdl import --dry-run .markdownlint.json

For comprehensive documentation on global settings (file selection, rule enablement, etc.), see our Global Settings Reference.

Inline Configuration

rumdl supports inline HTML comments to disable or configure rules for specific sections of your Markdown files. This is useful for making exceptions without changing global configuration:

<!-- rumdl-disable MD013 -->
This line can be as long as needed without triggering the line length rule.
<!-- rumdl-enable MD013 -->

Note: markdownlint-disable/markdownlint-enable comments are also supported for compatibility with existing markdownlint configurations.

For complete documentation on inline configuration options, see our Inline Configuration Reference.

Configuration File Example

Here's an example .rumdl.toml configuration file:

# Global settings
line-length = 100
exclude = ["node_modules", "build", "dist"]
respect-gitignore = true

# Disable specific rules
disabled-rules = ["MD013", "MD033"]

# Disable specific rules for specific files
[per-file-ignores]
"README.md" = ["MD033"]  # Allow HTML in README
"SUMMARY.md" = ["MD025"]  # Allow multiple H1 in table of contents
"docs/api/**/*.md" = ["MD013", "MD041"]  # Relax rules for generated docs

# Configure individual rules
[MD007]
indent = 2

[MD013]
line-length = 100
code-blocks = false
tables = false
reflow = true  # Enable automatic line wrapping (required for --fix)

[MD025]
level = 1
front-matter-title = "title"

[MD044]
names = ["rumdl", "Markdown", "GitHub"]

[MD048]
code-fence-style = "backtick"

Initializing Configuration

To create a configuration file, use the init command:

# Create a .rumdl.toml file (for any project)
rumdl init

# Create or update a pyproject.toml file with rumdl configuration (for Python projects)
rumdl init --pyproject

Configuration in pyproject.toml

For Python projects, you can include rumdl configuration in your pyproject.toml file, keeping all project configuration in one place. Example:

[tool.rumdl]
# Global options at root level
line-length = 100
disable = ["MD033"]
include = ["docs/*.md", "README.md"]
exclude = [".git", "node_modules"]
ignore-gitignore = false

# Rule-specific configuration
[tool.rumdl.MD013]
code_blocks = false
tables = false

[tool.rumdl.MD044]
names = ["rumdl", "Markdown", "GitHub"]

Both kebab-case (line-length, ignore-gitignore) and snake_case (line_length, ignore_gitignore) formats are supported for compatibility with different Python tooling conventions.

Configuration Output

Effective Configuration (rumdl config)

The rumdl config command prints the full effective configuration (defaults + all overrides), showing every key and its value, annotated with the source of each value. The output is colorized and the [from ...] annotation is globally aligned for easy scanning.

Example output

[global]
  enable             = []                             [from default]
  disable            = ["MD033"]                      [from .rumdl.toml]
  include            = ["README.md"]                  [from .rumdl.toml]
  respect_gitignore  = true                           [from .rumdl.toml]

[MD013]
  line_length        = 200                            [from .rumdl.toml]
  code_blocks        = true                           [from .rumdl.toml]
  ...

• ** Keys** are cyan, values are yellow, and the [from ...] annotation is colored by source:
  • Green: CLI
  • Blue: .rumdl.toml
  • Magenta: pyproject.toml
  • Yellow: default
• The [from ...] column is aligned across all sections.

Defaults Only (rumdl config --defaults)

The --defaults flag prints only the default configuration as TOML, suitable for copy-paste or reference:

[global]
enable = []
disable = []
exclude = []
include = []
respect_gitignore = true
force_exclude = false  # Set to true to exclude files even when explicitly specified

[MD013]
line_length = 80
code_blocks = true
...

Output Style

rumdl produces clean, colorized output similar to modern linting tools:

README.md:12:1: [MD022] Headings should be surrounded by blank lines [*]
README.md:24:5: [MD037] Spaces inside emphasis markers: "* incorrect *" [*]
README.md:31:76: [MD013] Line length exceeds 80 characters
README.md:42:3: [MD010] Hard tabs found, use spaces instead [*]

When running with --fix, rumdl shows which issues were fixed:

README.md:12:1: [MD022] Headings should be surrounded by blank lines [fixed]
README.md:24:5: [MD037] Spaces inside emphasis markers: "* incorrect *" [fixed]
README.md:42:3: [MD010] Hard tabs found, use spaces instead [fixed]

Fixed 3 issues in 1 file

For a more detailed view, use the --verbose option:

✓ No issues found in CONTRIBUTING.md
README.md:12:1: [MD022] Headings should be surrounded by blank lines [*]
README.md:24:5: [MD037] Spaces inside emphasis markers: "* incorrect *" [*]
README.md:42:3: [MD010] Hard tabs found, use spaces instead [*]

Found 3 issues in 1 file (2 files checked)
Run `rumdl fmt` to automatically fix issues

Output Format

Text Output (Default)

rumdl uses a consistent output format for all issues:

{file}:{line}:{column}: [{rule_id}] {message} [{fix_indicator}]

The output is colorized by default:

• Filenames appear in blue and underlined
• Line and column numbers appear in cyan
• Rule IDs appear in yellow
• Error messages appear in white
• Fixable issues are marked with [*] in green
• Fixed issues are marked with [fixed] in green

JSON Output

For integration with other tools and automation, use --output json:

rumdl check --output json README.md

This produces structured JSON output:

{
  "summary": {
    "total_files": 1,
    "files_with_issues": 1,
    "total_issues": 2,
    "fixable_issues": 1
  },
  "files": [
    {
      "path": "README.md",
      "issues": [
        {
          "line": 12,
          "column": 1,
          "rule": "MD022",
          "message": "Headings should be surrounded by blank lines",
          "fixable": true,
          "severity": "error"
        }
      ]
    }
  ]
}

Development

Prerequisites

• Rust 1.91 or higher
• Make (for development commands)

Building

make build

Testing

make test

JSON Schema Generation

If you modify the configuration structures in src/config.rs, regenerate the JSON schema:

# Generate/update the schema
make schema
# Or: rumdl schema generate

# Check if schema is up-to-date (useful in CI)
make check-schema
# Or: rumdl schema check

# Print schema to stdout
rumdl schema print

The schema is automatically generated from the Rust types using schemars and should be kept in sync with the configuration structures.
