Allow to use with multiple rules.

$ textlint --rule no-todo --rule very-nice-rule README.md

.textlintrc

.textlintrc is config file that is loaded as YAML, JSON or JS via MoOx/rc-loader.

$ textlint --rule no-todo --rule very-nice-rule README.md

is equal to

{
  "rules": {
    "no-todo": true,
    "very-nice-rule": true,
  }
}

The config object can define rule's option.

{
  "rules": {
    "no-todo": false, // disable
    "very-nice-rule": {
        "key": "value"
    }
  }
}

Pass rule's options("key": "value") to very-nice-rule.

It mean that use the following format:

{
  "rules": {
    "<rule-name>": true | false | object
  }
}

{
    "plugins": [
        "plugin-name"
    ],
    // overwrite-plugins rules config
    // <plugin>/<rule>
    "rules": {
        "plugin-name/rule-name" : false

:information_source: See docs/plugin.md

Rule list - Collection of textlint rule

See Collection of textlint rule · textlint/textlint Wiki.

If you create new rule, and add it to the wiki :)

Built-in formatters

Currently, you can use "stylish" (defaults), "compact", "checkstyle", "jslint-xml", "junit", "tap", "pretty-error", "json".

e.g.) use pretty-error.js

$ textlint -f pretty-error file.md

More detail in textlint/textlint-formatter.

Use as node modules

You can use textlint as node modules.

$ npm install textlint --save-dev

Minimal usage:

var TextLintEngine = require("textlint").TextLintEngine;
var engine = new TextLintEngine({
    rulePaths: ["path/to/rule-dir"]
});
var results = engine.executeOnFiles(["README.md"]);
console.log(results[0].filePath);// => "README.md"
// messages are `TextLintMessage` array.
console.log(results[0].messages);
/* 
[
    {
        id: "rule-name",
        message:"lint message",
        line: 1, // 1-based columns(TextLintMessage)
        column:1 // 1-based columns(TextLintMessage)
    }
]
 */
if (engine.isErrorResults(results)) {
    var output = engine.formatResults(results);
    console.log(output);
}

High level usage:

var textlint = require("textlint").textlint;
textlint.setupRules({
    // rule-key : rule function(see docs/create-rules.md)
    "rule-key": function(context){
        var exports = {};
        exports[context.Syntax.Str] = function (node) {
            context.report(node, new context.RuleError("error message"));
        };
        return exports;
    }
});
var results = cliEngine.executeOnFiles(["README.md"]);
console.log(results[0].filePath);// => "README.md"
console.log(results[0].messages);// => [{message:"lint message"}]
