A simple example
Here is a simple document example (colored version):
document( title: This is the document title. section: A first section The text is here. This one is *( in bold face )* and this one is _( underlined. )_ section: A second section /( This is the text in the second section. It is in italic. )/ )document
Important note: Fex is a Forth sublanguage. So each commands like title:,
*(, )/ ... are Forth words.
They need to be separated by spaces.
$ fex simple.fex
And the result looks like this:
Fex can be interactive (like Forth). Here are the available commands from the prompt line:
bye, make-dvi, make-ps, view-ps, pdf, make-pdf, view-pdf, save-ps, save-pdf, clean, clean-all, print
You can type 'help' or 'usage' at prompt time to have more actions details.
You can also download the source from the git repository:
git clone git://github.com/pbrochard/fex.git
Extract the tar.gz archive somewhere:
$ tar xzvf fex-N.tar.gz
And copy the fex file somewhere in your $PATH. For example, as root:
cp fex /usr/local/bin
Or if you want an English version:
cp fex-en /usr/local/bin/fex
To build a document you'll need to have gforth, latex, dvips, gv, xpdf and lpr installed on your system.
Fex is simple to extend. For example, you can change the pdf viewer with a change in the 'pdf' word (one line).
You can also add your own commands to fex. See the section near the end of the file where commands words are defined. A new command is auto documented directly in the word command.
Indeed a new command can be added at the begining of the document file.
