Developers documentation
|
|
------------------------
|
|
|
|
The goal is to provide useful source documentation. Right
|
|
now this is limited to libgimp since that is the part that
|
|
is by third-party coders (plug-in developers). Other parts
|
|
of the code may follow later, but not before libgimp is
|
|
properly documented.
|
|
|
|
|
|
Principle
|
|
---------
|
|
The documentation is extracted out of the source using
|
|
gtk-doc. We use a combination of comment blocks embedded
|
|
into the source and additional information added manually
|
|
into the SGML files. It is planned to extract useful
|
|
inforamtion about the PDB wrappers out of the PDB
|
|
(probably using pdbgen).
|
|
|
|
|
|
Requirements
|
|
------------
|
|
GIMP releases will contain a complete set of HTML files and
|
|
the SGML files to create other formats. You will only need
|
|
gtk-doc if you want to work on the documentation itself.
|
|
In that case you will need the following utilities:
|
|
|
|
Perl v5 - the main scripts are in Perl.
|
|
|
|
DocBook DTD v3.0 - This is the DocBook SGML DTD.
|
|
http://www.ora.com/davenport
|
|
|
|
Jade v1.1 - This is a DSSSL processor for converting SGML
|
|
to various formats.
|
|
http://www.jclark.com/jade
|
|
|
|
Modular DocBook Stylesheets (v1.19+ should be OK)
|
|
This is the DSSSL code to convert DocBook to HTML (and
|
|
a few other formats). It's used together with jade.
|
|

|
|
|
|
gtk-doc - This package automatically generates DocBook
|
|
documentation for GTK+ and converts the DocBook
|
|
documentation into HTML (and man pages in future).

|
HOWTO
|
|
-----
|
|
Carefully read the README that comes with gtk-doc. Then
|
|
read it again! The following lines will only give you hints
|
|
about how our system works. You should have understood the
|
|
principles of gtk-doc before you touch it.
|
|
|
|
The system is already set up so unless there are substantial
|
|
changes to the source e.g. new files were added, functions
|
|
were added, renamed or removed or parameters changed, there
|
|
is no need to repeat the scan step or rebuild the templates.
|
|
|
|
The Makefile will only work if gtk-doc was successfully
|
|
found when configure was ran. To rerun the scan step you also
|
|
need to have gimp installed (the version you are documenting)
|
|
and the correct version of gimptool should be found in your
|
|
PATH. If everything was set up correctly running a simple
|
|
make should do the trick and generate the SGML and HTML files
|
|
for you.
|
|
|
|
In most cases you will work on the documentation by adding or
|
|
editing comment blocks in the C source and by editing the
|
|
template SGML files in the tmpl dir. The following steps
|
|
should rebuild the documentation after a change:
|
|
|
|
make sgml - Creates the SGML files from the templates found
|
|
in the tmpl dir and from the comment blocks found
|
|
in the source.
|
|
|
|
make html - Build HTML pages out of the SGML files.
