M2HTML - Documentation System for MATLAB files in HTML

This toolbox is intended to provide automatic generation of M-files documentation in HTML. It reads each M-file in a set of directories (eventually recursively) to produce a corresponding HTML file containing synopsis, H1 line, help, function calls and called functions with hypertext links, syntax highlighted source code with hypertext, ...

Warning

This toolbox has been written between 2001 and 2005 (for MATLAB 5.3). It probably requires a complete rewrite and there are many great features that could be added, taking advantage of the very different web development landscape than two decades ago. This means that contributions via pull requests or feature requests via opening issues are very much welcome.

Here is a summary of the features of the toolbox:

• extraction of H1 lines and help of each function
• hypertext documentation with functions calls and called functions
• extraction of subfunctions (hypertext links)
• ability to work recursively over the subdirectories of a file tree
• ability to choose whether the source code must be included or not
• syntax highlighting of the source code (as in the MATLAB Editor)
• ability to choose HTML index file name and extension
• automatic creation of a TODO list (using % TODO % syntax)
• "skins": fully customizable output thanks to HTML templates (see below)

M2HTML may be particularly useful if you want to study code written by someone else (a downloaded toolbox, ...) because you will obtain an hypertext documentation in which you can easily walk through, thanks to your web browser.

INSTALLATION

0. Requirements:

• MATLAB 5.3 or above, or GNU Octave
• Operating system: any.

1. Download the most recent release from this website and extract files in your MATLAB Repository /home/foo/matlab/ (or clone this repository) :

unzip m2html.zip

2. Add the m2html directory in your MATLAB path:

addpath /home/foo/matlab/m2html/

3. Ready to use !

help m2html

If you want to generate dependency graphs, you need to install GraphViz, an open source graph visualization software.

TUTORIAL

One important thing to take care of is the MATLAB current directory: m2html must be launched one directory above the directory your wanting to generate documentation for.

For example, imagine your MATLAB code is in the directory /home/foo/matlab/ (or C:\foo\matlab\ on Windows), then you need to go in the foo directory:

cd /home/foo  % (or cd C:\foo on Windows)

and launch m2html with the command:

m2html('mfiles','matlab', 'htmldir','doc');

It will populate all the m-files just within the matlab directory, will parse them and then will write in the newly created doc directory (/home/foo/doc/, resp., C:\foot\doc\) an HTML file for each M-file.

You can also specify several subdirectories using a cell array of directories:

m2html('mfiles',{'matlab/signal' 'matlab/image'}, 'htmldir','doc');

If you want m2html to walk recursively within the matlab directory then you need to set up the recursive option:

m2html('mfiles','matlab', 'htmldir','doc', 'recursive','on');

You can also specify whether you want the source code to be displayed in the HTML files (do you want the source code to be readable from everybody ?):

m2html('mfiles','matlab', 'htmldir','doc', 'source','off');

You can also specify whether you want global hypertext links (links among separate MATLAB directories). By default, hypertext links are only among functions in the same directory (be aware that setting this option may significantly slow down the process).

m2html('mfiles','matlab', 'htmldir','doc', 'global','on');

Other parameters can be tuned for your documentation, see the M2HTML help:

help m2html

CUSTOMIZATION

This toolbox uses the HTML Template class so that you can fully customize the output. You can modify .tpl files in templates/blue/ or create new templates in a new directory (templates/othertpl).

You can then use the newly created template in specifying it:

m2html( ... , 'template','othertpl');

M2HTML will use your .tpl files (master, mdir, mfile, graph, search and todo.tpl) and will copy all the other files (CSS, images, ....) in the root directory of the HTML documentation.
