Design goal: Allow the use of layout "modules", which are to LaTeX packages as layout files are to LaTeX document classes. Thus, one could have a module that defined certain character styles, environments, commands, or what have you, and include it in various documents, each of which uses a different document class, without having to modify the layout files themselves. For example, a theorems.module could be used with article.layout to provide support for theorem-type environments, without having to modify article.layout itself, and the same module could be used with book.layout, etc.
This first patch does some reworking of the infrastructrue. We need to distinguish between the TextClass that a particular document is using and the layout of that document, since modules, in particular, can modify the layout. The solution adopted here is to add a TextClass pointer to BufferParams, which will hold the layout. The layout itself is then constructed from the TextClass the document is using. At present, this is completely trivial, but that will change when modules are added.
The pointer in question is a boost::shared_ptr. This is needed because CutAndPaste saves a copy of the layout with each cut or copied selection. We cannot assume the selection vanishes when the document is closed, so there are two options: (i) keep a list of all the layouts that have ever been used by any document; (ii) used some kind of smart pointer. The latter seems preferable, as the former would waste memory. More importantly, the use of a smart pointer allows modules to be modified on disk and then reloaded while LyX is running, and it will eventually allow the same for layout files.

The changes are essentially of three types.
First, the std::maps previously used here for storing BibTeX data have become full-fledged classes and so what were previously just a bunch of functions have now become methods of these new classes. This leads to a lot of minor changes in other files, to adapt to the new signature. The changes in insets/ are mostly of this kind.
Second, there are some slightly more substantial changes in src/insets/InsetBibtex.cpp. We now store lists of the field names and entry types that have been used.
Finally, there are the changes to the citation UI. These are mostly straightforward, though adding the new functionality exposed some inadequacies in the previous code that also had to be fixed.
One other change: BibTeX keys are now docstring. This solves some Unicode issues.
git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@19657 a592a061-630c-0410-9148-cb99ea01b6c8
a structure representing field->value instead of just a single string with
all the data. The data structures are defined in src/Biblio_typedefs.h, and
the main changes are to the parser code in src/insets/InsetBibtex.cpp.
-src/Biblio_typedefs.h
Contains typedefs for new representation. Separating them out limits how much
gets #include'd by other files, and also resolves a circularity problem with
Buffer.h.
-src/Biblio.{h,cpp}
Signature changes and massive simplifications to routines that report
BibTeX data, since we now have an articulate representation.
-src/insets/InsetBibtex.{h,cpp}
Re-write the parser code so we store a key->value map of the BibTeX data
rather than just one long string. This is the main work.
-src/frontends/controllers/ControlCitation.{h,cpp}
-src/insets/InsetBibitem.{h,cpp}
-src/insets/InsetCitation.cpp
Adaptations and simplifications.

information is acquired. This involves (i) moving the bulk of fillWithBibKeys()
into Biblio.cpp, (ii) introducing a virtual method Inset::fillWithBibKeys() that,
by default, does nothing, and (iii) over-riding this method in the insets that do
need to do something.
This is all preparatory for a more substantial re-working of the BibTex code,
which should follow shortly.

The key is the new copier script lib/scripts/ext_copy.py. Usage:
ext_copy.py [-e ext1,ext2,...] <from file> <to file>
Given a <from file> and <to file>, it will copy all files in the directory
in which from_file is found that have the extensions given in the -e option,
or all files in that directory if no such argument is given. So, for example,
we can do:
python ext_copy.py -e png,html,css /path/from/file.html /path/to/file.html
and all html, png, and css files in /path/from/ will be copied to the
(possibly new) directory /path/to/file.html.LyXconv/. The -t option determines
the extension added to the output filename passed to the script ($$o, in the
copier definition), the default being "LyXconv". If just . is given, then no
extension is added.
Other changes:
* configure.py: added appropriate copier definitions for html and wordhtml
formats, as well as for the Program pseudo-format.
* lib/Makefile.am and development/scons/scons_manifest.py: add ext_copy.py.
* lib/doc/Customization.lyx: update documentation.

Basically, I replaced all methods in the font_metrics namespace by a proper virtual interface FontMetrics. The FontLoader is _the_ container for FontMetrics.
This patch should also bring some optimizations in a number of place in the code. This is because we do not need any more to search for the LyXFont at each font_metrics call. In effect, the speed advantage is not as sensible and this is a bit deceiving considering that this was my primary motivation behind the patch. But I like the patch anyway as it cleans up the relation and interfacing between fonts, metrics and frontends.
* frontends/FontMetrics.h: new virtual interface. Renamed from font_metrics.h
* qt4/GuiFontMetrics: corresponding qt4 implememtation. Renamed from qfont_metrics.C. The smallCaps particular case treatment has been transfered here as well as the width cache for MacOSX and Windows.

My goal is to transfer all of "frontends/*/lyx_gui.C" to "frontends/lyx_gui.C". When this is done, "frontends/lyx_gui.C" can go altogether as its functions will then be replaced with direct calls to theApp->XXX().
* frontends/lyx_gui.C: new file with code transfered from [qt3,qt4,gtk]/lyx_gui.C
* frontends/Application: 3 new font related pure virtual methods
* [qt3,qt4,gtk]/GuiApplication: implement the above method with code transfered from lyx_gui.C

These font related functions were identical for qt3 and qt4. They are not Qt dependent at all and could also apply to an eventual Win32 or MacOSX gtk port.
Jen-Marc says: It would be nice to convince fontconfig to do the same for linux.
