  <h2 id="overview">What is EditorConfig?</h2>

  <p>EditorConfig helps developers define and maintain consistent coding styles between different editors and IDEs.  The EditorConfig project consists of <strong>a file format</strong> for defining coding styles and a collection of <strong>text editor plugins</strong> that enable editors to read the file format and adhere to defined styles.  EditorConfig files are easily readable and they work nicely with version control systems.</p>

</section>

<section id="file-format">

  <h2>What's an EditorConfig file look like?</h2>

  <section id="example-file">
    <h3>Example file</h3>
    <p>Below is an example <code>.editorconfig</code> file setting end-of-line and indentation styles for Python and JavaScript files.</p>
      <div class="code-container">
{% highlight ini %}
# EditorConfig is awesome: http://EditorConfig.org

# top-most EditorConfig file
root = true

# Unix-style newlines with a newline ending every file
[*]
end_of_line = lf
insert_final_newline = true

# Matches multiple files with brace expansion notation
# Set default charset
[*.{js,py}]
charset = utf-8

# 4 space indentation
[*.py]
indent_style = space
indent_size = 4

# Tab indentation (no size specified)
[Makefile]
indent_style = tab

# Indentation override for all JS under lib directory
[lib/**.js]
indent_style = space
indent_size = 2

# Matches the exact files either package.json or .travis.yml
[{package.json,.travis.yml}]
indent_style = space
indent_size = 2
{% endhighlight %}

  </section>

  <section id="file-location">
    <h3>Where are these files stored?</h3>

    <p>When opening a file, EditorConfig plugins look for a file named <code>.editorconfig</code> in the directory of the opened file and in every parent directory.  A search for <code>.editorconfig</code> files will stop if the root filepath is reached or an EditorConfig file with <code>root=true</code> is found.

    <p>EditorConfig files are read top to bottom and the closest EditorConfig files are read last.  Properties from matching EditorConfig sections are applied in the order they were read, so properties in closer files take precedence.</p>

    <p><strong>For Windows Users:</strong> To create an <code>.editorconfig</code> file within Windows Explorer, you need to create a file named <code>.editorconfig.</code>, which Windows Explorer will automatically rename to <code>.editorconfig</code>.</p>
  </section>

  <section id="file-format-details">
    <h3>File Format Details</h3>

    <p>EditorConfig files use an INI format that is compatible with the format used by <a href="https://docs.python.org/2/library/configparser.html">Python ConfigParser Library</a>, but <code>[</code> and <code>]</code> are allowed in the section names. The section names are filepath <a href="https://en.wikipedia.org/wiki/Glob_(programming)">globs</a>, similar to the format accepted by <a href="http://manpages.ubuntu.com/manpages/intrepid/man5/gitignore.5.html#contenttoc2">gitignore</a>. Forward slashes (<code>/</code>) are used as path separators and octothorpes (<code>#</code>) or semicolons (<code>;</code>) are used for comments. Comments should go on their own lines. EditorConfig files should be UTF-8 encoded, with either <code><abbr title="Carriage Return Line Feed">CRLF</abbr></code> or <code><abbr title="Line Feed">LF</abbr></code> line separators.</p>

    <p>Filepath glob patterns and currently-supported EditorConfig properties are explained below.</p>
  </section>

  <section id="wildcards">
    <h4>Wildcard Patterns</h4>

    <p>Special characters recognized in section names for wildcard matching:</p>

    <table>
      <tr><td><code>*</code></td><td>Matches any string of characters, except path separators (<code>/</code>)</td></tr>
      <tr><td><code>**</code></td><td>Matches any string of characters</td></tr>
      <tr><td><code>?</code></td><td>Matches any single character</td></tr>
      <tr><td><code>[name]</code></td><td>Matches any single character in <em>name</em></td></tr>
      <tr><td><code>[!name]</code></td><td>Matches any single character not in <em>name</em></td></tr>
      <tr><td><code>{s1,s2,s3}</code></td><td>Matches any of the strings given (separated by commas) (<strong>Available since EditorConfig Core 0.11.0</strong>)</td></tr>
      <tr><td><code>{num1..num2}</code></td><td>Matches any integer numbers between <em>num1</em> and <em>num2</em>, where num1 and num2 can be either positive or negative</td></tr>
    </table>

    <p>Special characters can be escaped with a backslash so they won't be interpreted as wildcard patterns.</p>
  </section>

  <section id="supported-properties">
    <h4>Supported Properties</h4>
    <p>Note that not all properties are supported by every plugin. The wiki has a <a href="https://github.com/editorconfig/editorconfig/wiki/EditorConfig-Properties">complete list of properties</a>.</p>
    <ul class="property-definitions">
      <li><dfn><code>indent_style</code></dfn>: set to <q>tab</q> or <q>space</q> to use hard tabs or soft tabs respectively.</li>
      <li><dfn><code>indent_size</code></dfn>: a whole number defining the number of columns used for each indentation level and the width of soft tabs (when supported).  When set to <q>tab</q>, the value of <strong><code>tab_width</code></strong> (if specified) will be used.</li>
      <li><dfn><code>tab_width</code></dfn>: a whole number defining the number of columns used to represent a tab character.  This defaults to the value of <strong><code>indent_size</code></strong> and doesn't usually need to be specified.</li>
      <li><dfn><code>end_of_line</code></dfn>: set to <q>lf</q>, <q>cr</q>, or <q>crlf</q> to control how line breaks are represented.</li>
      <li><dfn><code>charset</code></dfn>: set to <q>latin1</q>, <q>utf-8</q>, <q>utf-8-bom</q>, <q>utf-16be</q> or <q>utf-16le</q> to control the character set.  Use of <q>utf-8-bom</q> is discouraged.</li>
      <li><dfn><code>trim_trailing_whitespace</code></dfn>: set to <q>true</q> to remove any whitespace characters preceding newline characters and <q>false</q> to ensure it doesn't.</li>
      <li><dfn><code>insert_final_newline</code></dfn>: set to <q>true</q> to ensure file ends with a newline when saving and <q>false</q> to ensure it doesn't.</li>
      <li><dfn><code>root</code></dfn>: special property that should be specified at the top of the file outside of any sections.  Set to <q>true</q> to stop <code>.editorconfig</code> files search on current file.</li>
    </ul>

    <p>Currently all properties and values are case-insensitive. They are lowercased when parsed. Generally, if a property is not specified, the editor settings will be used, i.e. EditorConfig takes no effect on that part.</p>

    <p>It is acceptable and often preferred to leave certain EditorConfig properties unspecified.  For example, <strong><code>tab_width</code></strong> need not be specified unless it differs from the value of <strong><code>indent_size</code></strong>.  Also, when <strong><code>indent_style</code></strong> is set to <q>tab</q>, it may be desirable to leave <strong><code>indent_size</code></strong> unspecified so readers may view the file using their preferred indentation width.  Additionally, if a property is not standardized in your project (<strong><code>end_of_line</code></strong> for example), it may be best to leave it blank.</p>

  <section id="create-a-plugin">
    <h3>Create a plugin</h3>

    <p>EditorConfig plugins can be developed by using one of the EditorConfig core libraries.  The EditorConfig core libraries accept as input the file being edited, find and parse relevant <code>.editorconfig</code> files, and pass back the properties that should be used. Please ignore any unrecognized properties and property values in your editor plugin for future compatibility, since new properties and permitted values will be added in the future. Currently there is a <a href="https://github.com/editorconfig/editorconfig-core-c#readme">C library</a>, a <a href="https://github.com/editorconfig/editorconfig-core-py#readme">Python library</a>, a <a href="https://github.com/editorconfig/editorconfig-core-js#readme">JavaScript library</a>, a <a href="https://github.com/editorconfig/editorconfig-core-java#readme">Java library</a>, a <a href="https://github.com/editorconfig/editorconfig-core-lua#readme">lua library</a>, a <a href="https://github.com/editorconfig/editorconfig-core-net#readme">.NET library</a>, and a <a href="https://github.com/editorconfig/editorconfig-core-ruby">Ruby library</a>.</p>
    <p>If you are planning on creating a new plugin, use the <a href="http://groups.google.com/group/editorconfig">mailing list</a> to let us know so we can help out and link to your plugin once it's created.  If you plan on using one of the EditorConfig cores as a library or command line interface, the <a href="http://docs.editorconfig.org">C library documentation</a>, <a href="http://pydocs.editorconfig.org">Python library documentation</a> or <a href="http://javadocs.editorconfig.org">Java library documentation</a> may be helpful.</p>
