Hi list,
This is this bug: http://www.lyx.org/trac/ticket/3686
It has been around for a while, and continuously postponed. I would
have a hack at this. Here is how I think it can be solved:
- configure.py and chkconfig.ltx are altered so that
textclass.lst retains the missing package information.
- LayoutFile.cpp reads this information in.
- When a unavailable layout is used, BufferParams.cpp can now
inform the user of the layout's requirements.
If this is the way to go, this involves a format change for the
textclass.lst file.
Either:
1. An extra field is added to textclass.lst which list:
a. the requirements, or maybe
b. only the missing requirements.
Missing requirements would obviously be better, since then the user
knows what to do.
2. The true/false field is replaced by an empty/missing field. When
empty, the class is available, otherwise this field lists the missing
requirements.
The empty/missing version is probably sufficient.
Please share your thoughts! Maybe the textclass.lst file format change
can be avoided altogether?
I don't see a sensible way to avoid that. The info we want is originally
in the layout files, and I don't think we want to get the info from there.
