Quickstart: Installation, usage, and build integrations

Install into your project:

> npm install markdown-proofing

Now, create a .markdown-proofing JSON file in the root of your project. Here's a simple one using a preset to get started:

{
  "presets": ["technical-blog"]
}

Now, run it (may require global npm installation to run directly at command line):

> markdown-proofing ./file1.md

Next, you could wire it up in your package.json as part of your build (or, perhaps as a lint step, you decide!).

Usage with Jekyll / Static Site Generators

This section is centered around Jekyll, but may work with other static site generators, too!

Jekyll itself doesn't use npm. But, markdown-proofing can still be used!

First, check if a package.json file exists in the repository root. If one does, great! If not, no problem -- simply create one using npm init.

After package.json exists, run npm install markdown-proofing --save-dev. This assumes you won't need this package available in your production environment.

Then, add or modify the package.json test script:

"scripts"{
  "test": "markdown-proofing _posts/*.md"
},

Adjust the above as necessary if the posts live in a different place, or if you use a different file extension.

Now, use npm test to run markdown-proofing on the posts!

Configuration

Configuration is specified in JSON.

By default .markdown-proofing located in the root of the project is used. You can optionally specify a different file using the -c / --configuration flags, if you'd like.

The configuration can be as simple as:

{
  "presets": ["technical-blog"]
}

Or, a bit more complex:

{
  "presets": [],
  "analyzers": [
    "require-oxford-commas",
    "sensitivity",
    "sentiment",
    "spelling",
    "statistics",
    "write-good"
  ],
  "rules": {
    "missing-oxford-commas": "error",
    "sensitivity": "warning",
    "sentiment-score": "info",
    "sentiment-comparative-score": "info",
    "spelling-error": "error",
    "statistics-flesch-kincaid-grade-level": "info, warning > 12",
    "statistics-flesch-kincaid-reading-ease": "warning <= 40",
    "write-good": "info"
  }
}

Spellcheck

The SpellingAnalyzer implements markdown-spellcheck. This package uses a .spelling file for permitting unrecognized text. Only global words are currently supported, though (no file specific words).

markdown-spellcheck also includes an interactive CLI, which you can use to interactively fix spelling and update the .spelling file as necessary. You may find this useful.

Core concepts

There are two core concepts: Analyzers and Rules.

  • Analyzers process the text!
    • Analyzers parse a markdown text string and return an AnalyzerResult, which includes a collection of AnalyzerMessage objects.
      • AnalyzerMessage's are { type: String, text: String, line: Number, column: Number }.
    • There are useful analyzers built-in and ready for use. Custom analyzers are supported as well.
  • Rules react to analyzers!
    • These react to the output of the configured analyzers. Without any rules, the output of the analyzers is not surfaced to the user or applied in any way. So, you'll need some rules!
    • Rules are in the format of '{{message-type}}': '{{condition}}'.
      • Example rule: 'statistics-word-count': 'info'
      • Example rule: 'statistics-flesch-kincaid-reading-ease': 'warning < 40'
    • There are four types of rules: info, warning, error, and none.
      • info signals to add this to any output. It should show up in build results and any place where messages should be visible.
      • warning is a standard warning, it shouldn't fail a build.
      • error violations should result in a build failure.
      • none is used to override a preset.
    • Rules can have an optional condition, which is applied as warning < 40 -- it's a warning only when the value is less than 40.
      • This is useful for statistics and other numerical outputs from analyzers.

Jekyll Integration

You can use the following to integrate with Jekyll:

package.json

"scripts"{
  "test": "markdown-proofing _posts/*.md",
  "proof": "markdown-proofing --color --no-throw --",
  "proof:all": "npm run test -- --no-throw",
  "proof:latest": "node proofScripts.js latest _posts/*.md",
  "proof:changed": "node proofScripts.js git-index-and-uncommitted _posts/*.md",
  "proof:index": "node proofScripts.js git-index _posts/*.md",
  "proof:uncommitted": "node proofScripts.js git-uncommitted _posts/*.md"
},
"devDependencies"{
  "shelljs": "^0.7.0"
}

proofScripts.js

require('shelljs/global');
 
const arg = process.argv[2];
if (!arg) {
  echo('Please specify a proofing instruction argument.');
  exit(1);
}
 
const filePattern = process.argv[3];
if (!filePattern) {
  echo('Please specify the file pattern as the last argument.');
  exit(1);
}
 
if (arg === 'latest') {
  const orderedPosts = ls('-l', filePattern)
    .filter(x => x.name)
    .map(x => x.name)
    .sort((a, b) => b.localeCompare(a));
 
  if (orderedPosts.length > 0) {
    const latestPost = orderedPosts[0];
    proof(latestPost);
  }
}
else if (arg === 'git-index') {
  gitProof(`git diff --name-only --cached ${filePattern}`);
}
else if (arg === 'git-uncommitted') {
  gitProof(`git diff --name-only --diff-filter=ACMRT ${filePattern}`);
}
else if (arg === 'git-index-and-uncommitted') {
  gitProof([
    `git diff --name-only --diff-filter=ACMRT ${filePattern}`,
    `git diff --name-only --cached' ${filePattern}`
  ]);
}
 
function gitProof(gitDiffPatterns) {
  if (!which('git')) {
    echo('This script requires git.');
    exit(1);
  }
 
  if (!Array.isArray(gitDiffPatterns)) {
    gitDiffPatterns = [ gitDiffPatterns ];
  }
 
  const files = [];
  gitDiffPatterns.forEach(x => {
    const gitDiffOutput = exec(x, { silent: true });
 
    if (gitDiffOutput.stderr) {
      throw new Error(gitDiffOutput.stderr);
    }
 
    if (gitDiffOutput.stdout) {
      files.push(gitDiffOutput.stdout);
    }
  });
 
  if (files.length === 0) {
    echo('No files to proof.');
    exit(0);
  }
 
  proof(files);
}
 
function proof(files) {
  if (!Array.isArray(files)) {
    files = [ files ];
  }
 
  const cmd = `npm run proof ${files.join(' ')}`;
  if (exec(cmd).code !== 0) {
    echo(`Error while running: ${cmd}`);
    exit(1);
  }
}

Custom Analyzers

import AnalyzerResult from 'markdown-proofing/analyzer-result'; // TODO: Change this import if this is not correct
 
export default class MyCustomAnalyzerAnalyzer {
  analyze(str) {
    const result = new AnalyzerResult();
 
    // As part of the logic, optionally add one or more messages:
    result.addMessage('my-custom-analyzer-message-type', 'some-value');
 
    // The return value can be an `AnalyzerResult`
    // or a promise to return an `AnalyzerResult`.
    return result;
  }
}

Then, simply wire it up in configuration as an analyzers array item:

{
  "presets": [
  ],
  "analyzers": [
    "path/to/custom-analyzer"
  ],
  "rules": {
    "custom-analyzer-message": "info"
  }
}
