Community discussion, questions, and informal bug reporting is done on the
|
| 10 |
+
[discuss.CodeMirror forum](http://discuss.codemirror.net).
|
| 11 |
+
|
| 12 |
+
## Submitting bug reports
|
| 13 |
+
|
| 14 |
+
The preferred way to report bugs is to use the
|
| 15 |
+
[GitHub issue tracker](http://github.com/codemirror/CodeMirror/issues). Before
|
| 16 |
+
reporting a bug, read these pointers.
|
| 17 |
+
|
| 18 |
+
**Note:** The issue tracker is for *bugs*, not requests for help. Questions
|
| 19 |
+
should be asked on the
|
| 20 |
+
[discuss.CodeMirror forum](http://discuss.codemirror.net) instead.
|
| 21 |
+
|
| 22 |
+
### Reporting bugs effectively
|
| 23 |
+
|
| 24 |
+
- CodeMirror is maintained by volunteers. They don't owe you anything, so be
|
| 25 |
+
polite. Reports with an indignant or belligerent tone tend to be moved to the
|
| 26 |
+
bottom of the pile.
|
| 27 |
+
|
| 28 |
+
- Include information about **the browser in which the problem occurred**. Even
|
| 29 |
+
if you tested several browsers, and the problem occurred in all of them,
|
| 30 |
+
mention this fact in the bug report. Also include browser version numbers and
|
| 31 |
+
the operating system that you're on.
|
| 32 |
+
|
| 33 |
+
- Mention which release of CodeMirror you're using. Preferably, try also with
|
| 34 |
+
the current development snapshot, to ensure the problem has not already been
|
| 35 |
+
fixed.
|
| 36 |
+
|
| 37 |
+
- Mention very precisely what went wrong. "X is broken" is not a good bug
|
| 38 |
+
report. What did you expect to happen? What happened instead? Describe the
|
| 39 |
+
exact steps a maintainer has to take to make the problem occur. We can not
|
| 40 |
+
fix something that we can not observe.
|
| 41 |
+
|
| 42 |
+
- If the problem can not be reproduced in any of the demos included in the
|
| 43 |
+
CodeMirror distribution, please provide an HTML document that demonstrates
|
| 44 |
+
the problem. The best way to do this is to go to
|
| 45 |
+
[jsbin.com](http://jsbin.com/ihunin/edit), enter it there, press save, and
|
| 46 |
+
include the resulting link in your bug report.
|
| 47 |
+
|
| 48 |
+
## Contributing code
|
| 49 |
+
|
| 50 |
+
Note that we are not accepting any new addons or modes into the main
|
| 51 |
+
distribution. If you've written such a module, please distribute it as
|
| 52 |
+
a separate NPM package.
|
| 53 |
+
|
| 54 |
+
- Make sure you have a [GitHub Account](https://github.com/signup/free)
|
| 55 |
+
- Fork [CodeMirror](https://github.com/codemirror/CodeMirror/)
|
| 56 |
+
([how to fork a repo](https://help.github.com/articles/fork-a-repo))
|
| 57 |
+
- Make your changes
|
| 58 |
+
- If your changes are easy to test or likely to regress, add tests.
|
| 59 |
+
Tests for the core go into `test/test.js`, some modes have their own
|
| 60 |
+
test suite under `mode/XXX/test.js`. Feel free to add new test
|
| 61 |
+
suites to modes that don't have one yet (be sure to link the new
|
| 62 |
+
tests into `test/index.html`).
|
| 63 |
+
- Follow the general code style of the rest of the project (see
|
| 64 |
+
below). Run `bin/lint` to verify that the linter is happy.
|
| 65 |
+
- Make sure all tests pass. Visit `test/index.html` in your browser to
|
| 66 |
+
run them.
|
| 67 |
+
- Submit a pull request
|
| 68 |
+
([how to create a pull request](https://help.github.com/articles/fork-a-repo)).
|
| 69 |
+
Don't put more than one feature/fix in a single pull request.
|
| 70 |
+
|
| 71 |
+
By contributing code to CodeMirror you
|
| 72 |
+
|
| 73 |
+
- agree to license the contributed code under CodeMirror's [MIT
|
| 74 |
+
license](http://codemirror.net/LICENSE).
|
| 75 |
+
|
| 76 |
+
- confirm that you have the right to contribute and license the code
|
| 77 |
+
in question. (Either you hold all rights on the code, or the rights
|
| 78 |
+
holder has explicitly granted the right to use it like this,
|
| 79 |
+
through a compatible open source license or through a direct
|
| 80 |
+
agreement with you.)
|
| 81 |
+
|
| 82 |
+
### Coding standards
|
| 83 |
+
|
| 84 |
+
- 2 spaces per indentation level, no tabs.
|
| 85 |
+
|
| 86 |
+
- Note that the linter (`bin/lint`) which is run after each commit
|
| 87 |
+
complains about unused variables and functions. Prefix their names
|
| 88 |
+
with an underscore to muffle it.
|
| 89 |
+
|
| 90 |
+
- CodeMirror does *not* follow JSHint or JSLint prescribed style.
|
| 91 |
+
Patches that try to 'fix' code to pass one of these linters will be
|
| 92 |
+
unceremoniously discarded.

### Installation
|
| 33 |
+
|
| 34 |
+
Either get the [zip file](https://codemirror.net/codemirror.zip) with
|
| 35 |
+
the latest version, or make sure you have [Node](https://nodejs.org/)
|
| 36 |
+
installed and run:
|
| 37 |
+
|
| 38 |
+
npm install codemirror
|
| 39 |
+
|
| 40 |
+
**NOTE**: This is the source repository for the library, and not the
|
| 41 |
+
distribution channel. Cloning it is not the recommended way to install
|
| 42 |
+
the library, and will in fact not work unless you also run the build
|
| 43 |
+
step.
|
| 44 |
+
|
| 45 |
+
### Quickstart
|
| 46 |
+
|
| 47 |
+
To build the project, make sure you have Node.js installed (at least version 6)
|
| 48 |
+
and then `npm install`. To run, just open `index.html` in your
|
| 49 |
+
browser (you don't need to run a webserver). Run the tests with `npm test`.

// Define an extended mixed-mode that understands vbscript and

|
| 59 |

var mixedMode = {
|
| 60 |
+
name: "htmlmixed",
|
| 61 |
+
scriptTypes: [{matches: /\/x-handlebars-template|\/x-mustache/i,

{matches: /(text|application)\/(x-)?vb(a|script)/i,
|
| 64 |

mode: "vbscript"}]
|
| 65 |
+
};
|
| 66 |
+
var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
|
| 67 |

</script>
|
| 71 |
+
|
| 72 |
+
<p>The HTML mixed mode depends on the XML, JavaScript, and CSS modes.</p>
|
| 73 |
+
|
| 74 |
+
<p>It takes an optional mode configuration
|
| 75 |
+
option, <code>tags</code>, which can be used to add custom
|
| 76 |
+
behavior for specific tags. When given, it should be an object
|
| 77 |
+
mapping tag names (for example <code>script</code>) to arrays or
|
| 78 |
+
three-element arrays. Those inner arrays indicate [attributeName,
|
| 79 |
+
valueRegexp, <a href="../../doc/manual.html#option_mode">modeSpec</a>]
|
| 80 |
+
specifications. For example, you could use <code>["type", /^foo$/,
|
| 81 |
+
"foo"]</code> to map the attribute <code>type="foo"</code> to
|
| 82 |
+
the <code>foo</code> mode. When the first two fields are null
|
| 83 |
+
(<code>[null, null, "mode"]</code>), the given mode is used for
|
| 84 |
+
any such tag that doesn't match any of the previously given
|
| 85 |
+
attributes. For example:</p>
|
| 86 |
+
|
| 87 |
+
<pre>var myModeSpec = {
|
| 88 |
+
name: "htmlmixed",
|
| 89 |
+
tags: {
|
| 90 |
+
style: [["type", /^text\/(x-)?scss$/, "text/x-scss"],
|
| 91 |
+
[null, null, "css"]],
|
| 92 |
+
custom: [[null, null, "customMode"]]
|
| 93 |
+
}
|
| 94 |
+
}</pre>
|
| 95 |
+
|
| 96 |
+
<p><strong>MIME types defined:</strong> <code>text/html</code>
|
| 97 |
+
(redefined, only takes effect if you load this parser after the
|
| 98 |
+
XML parser).</p>

<h2>Language modes</h2>
|
| 23 |
+
|
| 24 |
+
<p>This is a list of every mode in the distribution. Each mode lives
|
| 25 |
+
in a subdirectory of the <code>mode/</code> directory, and typically
|
| 26 |
+
defines a single JavaScript file that implements the mode. Loading
|
| 27 |
+
such file will make the language available to CodeMirror, through
|
| 28 |
+
the <a href="../doc/manual.html#option_mode"><code>mode</code></a>
|
| 29 |
+
option.</p>

JavaScript mode supports several configuration options:
|
| 93 |
+
<ul>
|
| 94 |
+
<li><code>json</code> which will set the mode to expect JSON
|
| 95 |
+
data rather than a JavaScript program.</li>
|
| 96 |
+
<li><code>jsonld</code> which will set the mode to expect
|
| 97 |
+
<a href="http://json-ld.org">JSON-LD</a> linked data rather
|
| 98 |
+
than a JavaScript program (<a href="json-ld.html">demo</a>).</li>
|
| 99 |
+
<li><code>typescript</code> which will activate additional
|
| 100 |
+
syntax highlighting and some other things for TypeScript code
|
| 101 |
+
(<a href="typescript.html">demo</a>).</li>
|
| 102 |
+
<li><code>statementIndent</code> which (given a number) will
|
| 103 |
+
determine the amount of indentation to use for statements
|
| 104 |
+
continued on a new line.</li>
|
| 105 |
+
<li><code>wordCharacters</code>, a regexp that indicates which
|
| 106 |
+
characters should be considered part of an identifier.
|
| 107 |
+
Defaults to <code>/[\w$]/</code>, which does not handle
|
| 108 |
+
non-ASCII identifiers. Can be set to something more elaborate
|
| 109 |
+
to improve Unicode support.</li>

The indentation tries to be <em>somewhat &quot;do what

<p>The XML mode supports these configuration parameters:</p>
|
| 46 |
+
<dl>
|
| 47 |
+
<dt><code>htmlMode (boolean)</code></dt>
|
| 48 |
+
<dd>This switches the mode to parse HTML instead of XML. This
|
| 49 |
+
means attributes do not have to be quoted, and some elements
|
| 50 |
+
(such as <code>br</code>) do not require a closing tag.</dd>
|
| 51 |
+
<dt><code>matchClosing (boolean)</code></dt>
|
| 52 |
+
<dd>Controls whether the mode checks that close tags match the
|
| 53 |
+
corresponding opening tag, and highlights mismatches as errors.
|
| 54 |
+
Defaults to true.</dd>
|
| 55 |
+
<dt><code>alignCDATA (boolean)</code></dt>
|
| 56 |
+
<dd>Setting this to true will force the opening tag of CDATA
|
| 57 |
+
blocks to not be indented.</dd>
