An implementation of MATLAB syntax highlighting for google-code-prettify.
The following constructs are recognized:
- single line and block comments (
% commentand%{,%}) - quoted string (
'hello world') - number literals (
1,-2.5,1i,2.9E-5, etc...) - shell escape (
!touch filename) - line continuation (
...) - transpose operator (
x'andx.') - command prompt (
>> now) - error/warning messages (
??? Error in ...andWarning: ...) - parentheses, brackets, braces (
(),[],{}) - other operators (
<>=~@&;,:!-+*^.|\/) - MATLAB language keywords (
if,else,end, etc...) - some special variables and constants (
inf,nan,varargin, etc..) - user-defined indentifiers (function and variable names not matched in previous steps)
The "full" version also adds highlighting for MATLAB functions:
- over 1300 builtin functions from core MATLAB (
cos,plot, etc...) - additional functions from popular toolboxes (Statistics, IPT, and Optimization)
(Since this increases the resulting script size, a separate "lite" version is also available which excludes function names detection).
The project was inspired by the similar Mathematica.SE syntax highlighter.
Requirements: Node.js and the NPM package manager.
To rebuild the project, run the following in the command line:
$ cd prettify-matlab
$ npm install
$ npm run build
# (optional) run unit tests
$ npm testFirst this will install build dependencies, then generate the output
javascript and stylesheet files in the dist directory using the
source templates from the src directory.

To apply the MALTAB syntax highlighting on code snippets in your own web pages, first include the prettify scripts and stylesheets in your document (as explained in the code-prettify project documentation). Next include the MATLAB language extension, and place your source code inside a preformatted HTML tag as follows:
<html>
<head>
<title>MATLAB</title>
<link rel="stylesheet" type="text/css" href="prettify.css" />
<script src="prettify.js"></script>
<script src="lang-matlab.js"></script>
</head>
<body onload="prettyPrint();">
<pre class="prettyprint lang-matlab">
% example code
x = [1, 2, 3]';
fprintf('sum(x^2) = %f\n', sum(x.^2));
</pre>
</body>
</html>When PR.prettyPrint() is called, marked sections will be pretty-printed, and
the default styles will be applied. You can customize them with your own, or
use the provided stylesheet which has a color scheme
inspired by that of the MATLAB IDE (with some modifications).
See the demo page for a demonstration.
UPDATE: The MATLAB extension is now integrated upstream in google/code-prettify. So you can use the auto-loader to directly load both code-prettify along with the MATLAB extension via one URL:
<script src="https://cdn.rawgit.com/google/code-prettify/master/loader/run_prettify.js?lang=matlab"></script>For instructions on installing userscripts for various browsers, see this page. Also check out the wiki for sample screenshots.
Apply MATLAB syntax highlighting on Stack Overflow and other
Stack Exchange sites. The script is only activated on questions tagged as
matlab.
In addition, a separate userscript is included to allow switching the language used by the prettifier. It adds a small button to the top-right corner of each code block, with an attached drop-down menu to allow language selection.
UPDATE: Stack Overflow recently integrated MATLAB syntax support, so you should get proper syntax highlighting by default. This userscript is still useful if you want to get full highlighting for function names as well as the customized stylesheet which applies colors resembling the MATLAB editor.
