* putenv.diff: allocate space for the exported string and store the
pointers in a static map<>. Pointers are deleted when a variable is
overwritten, so the function doesn't leak memory.
* export-socket.diff: export variables EDITOR and LYXSOCKET when the
socket is created. Since there is no need of passing the socket address
through $$a, it is removed from format.C. Xdvi must then be called with no
arguments, and kdvi works if the editor is defined as 'lyxclient -g %f
%l'.
* export-lyxclient.diff: makes lyxclient work with LYXSOCKET environment
variable.
* lyxclient.man: manual page for lyxclient. I again ask some native
english speaker to revise it, please.
* socket-qt.diff: bring lyxsocket to qt.
* socket_callback.{C,h}: class analogous to io_callback for sockets. They
must be placed under src/frontends/qt2.
TODO:
* make lib/configure detect if there is a --src or --src-specials option
available for latex or if there is a srcltx.sty package and then set the
variable
\srcspecials latexoption "--src-specials"
or
\srcspecials package "srcltx.sty"
(or whatever is best)
* Make latex generate source specials only when previewing, not when
exporting DVI. Alfredo, I have been looking at the "flavours" code. Do you
think that a good solution would be defining a latex + src specials
flavour?
* forward search.
Regards,
Jo�o.
