New Revision: 127971
URL:
http://svn.digium.com/view/asterisk?view=rev&rev=127971
Log:
Sort of a long commit message.
Added a TODO list with ideas that me and
mvanbaak already had (including russells
dialplan idea)
Added a script to pull DOCUMENTATION xml out
of files (will be used at build time to generate
a single xml file, or multiple xml files of documentation)
Updated app_dial to reflect those changes.
(APP/DOCUMENTATION)
Try it with:
awk -f build_tools/get_documentation apps/app_dial.c
Hardcoded iksemel in pbx.c (obviously this is going
to need to be changed, so asterisk does not depend
on iksemel as it currently does)
added ast_register_application_xml that is going
to fetch descrip, etc, from the xml blob.
It builds and loads.

+*****XML Documentation Conversation*****
+
+Goal: To convert the static documentation held within
+all parts of Asterisk (non-code/non-doxygen) into a
+parseable format (XML) to be loaded on runtime.
+
+This would provide all the documentation currently in
+Asterisk to any other source that supports some kind of
+XML Conversion.
+
+One end result usage would be to be able to verify dialplans
+based on arguments/results/types of dialplan applications,
+functions, and anything else that can be regulated to some degree.
+
+
+So far mvanbaak added an example in apps/app_dial.c of
+an XML tree of the Dial application.
+
+
+**** Todo ****
+
+ONCE we have a acceptable format that most agree on, we will
+need to convert all the applications to use this method (obviously).
+
+Define a set of rules/ideas that you want to pull out of the documentation.
+
+The reason for this is so we do not go back and say, "Oh, we should have
+added the ability to do X, which is in the code/documentation and
+can be pulled out in a reliable way. Now we have to do that for
+all the Documentation we have already converted.
+
+
+Finish ast_register_application_xml
+
+Finish the parsing of /var/lib/asterisk/documentation.xml
+
+Add the parsing of files to one xml blob, and copying to
+/var/lib/asterisk/documentation.xml
