This is one of a series of patches that will merge the layout modules development in personal/branches/rgheck back into the tree. 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 patch adds the backend. The ModuleList class holds a list of the available modules, which are retrieved from lyxmodules.lst, itself generated by configure.py. There are two LFUNs available: modules-clear and module-add, which do the obvious thing; you can test by typing these into the minibuffer, along with the name of one of the available modules: URL (a CharStyle), Endnote (a Custom Inset), and---with the spaces---End To Foot (View>LaTeX and look at the user preamble), which are themselves in lib/layouts. There are some others, too, that allow theorems to be added to classes like article and book. The GUI will come next. Issues: (i) The configure.py script could be improved. It'd be nice, for example, if it tested for the presence of the LaTeX packages a particular module needs. But this would mean re-working the LaTeX script, and I don't know how to do that. Note that at present, the packages are ignored. This will change shortly. (ii) I've used std::string in LyXModule, following what seemed to be a precedent in TextClass. If some of these should be docstrings, please let me know, and I'll change them. (iii) There is at present no distinction between LaTeX and DocBook modules. Should there be? That is: Should there be modules that are available when the document class is a LaTeX class and others that are available only when it is DocBook? Or should there just be one set of modules? Each module can of course indicate for what it is suitable in its description. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@19893 a592a061-630c-0410-9148-cb99ea01b6c8

/*
Signals and Windows
===================
The SIGHUP signal does not exist on Windows and does not need to be handled.
Windows handles SIGFPE and SIGSEGV signals as expected.
Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
cause a new thread to be spawned. This may well result in unexpected
behaviour by the single-threaded LyX.
SIGTERM signals will come only from another process actually sending
that signal using 'raise' in Windows' POSIX compatability layer. It will
not come from the general "terminate process" methods that everyone
actually uses (and which can't be trapped). Killing an app 'politely' on
Windows involves first sending a WM_CLOSE message, something that is
caught already by the Qt frontend.
For more information see:
http://aspn.activestate.com/ASPN/Mail/Message/ActiveTcl/2034055
...signals are mostly useless on Windows for a variety of reasons that are
Windows specific...

This is one of a series of patches that will merge the layout modules development in personal/branches/rgheck back into the tree. 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 patch adds the backend. The ModuleList class holds a list of the available modules, which are retrieved from lyxmodules.lst, itself generated by configure.py. There are two LFUNs available: modules-clear and module-add, which do the obvious thing; you can test by typing these into the minibuffer, along with the name of one of the available modules: URL (a CharStyle), Endnote (a Custom Inset), and---with the spaces---End To Foot (View>LaTeX and look at the user preamble), which are themselves in lib/layouts. There are some others, too, that allow theorems to be added to classes like article and book. The GUI will come next. Issues: (i) The configure.py script could be improved. It'd be nice, for example, if it tested for the presence of the LaTeX packages a particular module needs. But this would mean re-working the LaTeX script, and I don't know how to do that. Note that at present, the packages are ignored. This will change shortly. (ii) I've used std::string in LyXModule, following what seemed to be a precedent in TextClass. If some of these should be docstrings, please let me know, and I'll change them. (iii) There is at present no distinction between LaTeX and DocBook modules. Should there be? That is: Should there be modules that are available when the document class is a LaTeX class and others that are available only when it is DocBook? Or should there just be one set of modules? Each module can of course indicate for what it is suitable in its description. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@19893 a592a061-630c-0410-9148-cb99ea01b6c8
