PS_View README
This is PS_View (a previewing utility for Ghostscript interpreter)
version 5.12. It is TeX-Live 2009 release -- it is fully
functional and needs through testing. It can be used as a basic
PostScript viewer, but it still probably has bugs.
It is written using wxWidgets, wxLua and wxGhostscript libriares.
Curently, it works under Windows and Linux. It should work also
under Mac OS X. It would be marvellous if the bold Mac OS X-ers
could verify it.
Sources needed to recompile the program are in a separate zip file
(note that it doesn't contain the Lua and PostScript scripts needed
to run the program).
Package consists of:
README -- this file
gswxluas -- wxLuaGhostscript executable (ELF) file
gswxlua.exe -- wxLuaGhostscript executable (WIN32) file
psv.wx.lua -- wxLua part of PS_View program
psv_view.ps -- PostScript part of PS_View program
psv -- bash script for linux
psv.bat -- batch script for windows
psv.desktop -- info file for Xwindow users
psv.xpm -- icon for Xwindow
psv_about*.ps -- about info files
psv_help*.htb -- help files
psv_usage*.pdf -- usage help files
pl/, de/, en/, nl/ -- locale messages
Usage: psv[.bat] [Postscript/PDF file]
or
Usage: gswxlua [-h|--help] [-c|--console] [-l|--lua] psv.wx.lua [options] [-p|--ps] psv_view.ps [-- [more options]]
-h, --help help on command line arguments;
-c, --console show message console;
-l, --lua wxLua script to construct application;
-q, --quiet turn off most of messages;
-v, --verbose turn on verbose/debug mode;
-n, --new open new window for document;
-g, --gsdll path to Ghostscript dll/so file;
-i, --gslib paths to Ghostscript init files;
-s, --gsset Ghostscript parameter (-s equivalent);
-d, --gsdef Ghostscript parameter (-d equivalent);
-p, --ps PostScript program to run;
-- all following argument will be passed to Ghostscript;
Some paths are discovered automatically:
1) first, all the relevant files are searched along the path given
in the command line (absolute or relative with respect to the
current directory)
2) next, the files are searched in the directories defined in the config
file [TODO: editing of the config file]
3) the Lua file is additionaly searched in the directory
where the executable file has been found
3a) in turn, the PostScript file is searched in the directory
where the Lua file was found
3b) if the search described in the points 3, 3a was needed, the resulting
path is added to the search path of the Ghostscript input files
4) the Ghostscript library file (.dll or .so) is searched along the path
given in the command line (-g option)
4a) then it is searched along the path defined by the GS_DLL environment
variable
4b) if all attempts so far fail, the last resort in Unix is the
standard library directory (/usr/local/lib, /usr/lib) and in
Windows is the register key (HKEY_LOCAL_MACHINE/SOFTWARE/GPL_Ghostscript)
4c) if the the Ghostscript library file was found in the points 2 or 4,
the subdirectory lib/ of the relevant Ghostscript tree is also added
to the search path of the Ghostscript input files
