Port of GraphViz and LuaGRAPH toolkit to Windows
by Graham Douglas 21 Nov '10

21 Nov '10

Hi All Apologies in advance for the long e-mail... I'm wondering if any other Windows users/developers would find the following helpful/useful/interesting... if so I'd be delighted to share the code etc for others to explore --- and improve! Subject to making sure that distributing this work is OK in terms of the GraphViz and LuaGRAPH toolkit licences. I need to check that. I'm giving a bit of background info, as it may be of interest to other developers -- perhaps I can expand this to add to a Wiki somewhere? Any suggestions where to put it (if of interest) would be welcome. Inspired by Luigi's brilliant work on luatex lunatic --- which still amazes me every time I look at it -- I too wanted to use GraphViz (but on Windows) to probe LuaTeX node structures. Why should the Linux guys have all the fun ;-))) However, I could not get the DLLs shipped with the GraphViz distribution to work (for me anyway). Not saying they won't work just that I could not get them to work for me. I decided to build a fresh port of GraphViz for Windows, with a binding to Lua using the LuaGRAPH toolkit by Herbert Leuwer. In summary, I took the Visual Studio solution shipped with GraphViz source code distribution and modified it to build .lib files and then compile everything into a single DLL, including the essential core plug-ins. I have excluded a number of libraries including Cairo etc which I didn't want or need for my purposes. I just wanted the core GraphViz functionality scriptable by the LuaGRAPH toolkit and spitting out a PostScript file, which I convert to PDF with GhostScript. The result is a single DLL combining the LuaGRAPH toolkit and most of the core GraphViz, giving access to the full Lua binding written by Herbert Leuwer. Anyone who has looked at the GraphViz source will know that it is designed to dynamically load lots of things from external libraries (DLLs on Windows). Because the core plug-ins are now built into in a single DLL I had to slightly modify the initialisation and library-loading done via LuaGRAPH toolkit --- turned out to be just a few lines of C, modifying the LuaGRAPH toolkit function void gv_init(void) using the gvc function gvconfig_plugin_install_from_library I have tested the DLL using examples on the GraphViz site and they seem to work OK. So, after this long explanation my question is would anyone else who is working on Windows have any use for this? If so, after checking the licences and some more testing.... I'd be delighted to release it (but where!!!) for others to use "as is" with the note that it is quite experimental and that I don't intend to support it. If anyone has written Lua code for the LuaGRAPH toolkit as a way of inspecting LuaTeX nodes I'd be extremely grateful to have some small samples with which to further test the library. I'd be happy to receive the community's view on whether this Windows port of GraphViz and LuaGRAPH toolkit could be useful to anyone --- and I'd be very grateful for Lua/LuaTeX code to test it with :-) LuaTeX has provided me with a fasinating hobby and I'd like to give a little bit back, where I can. If anyone wants a copy of the DLL (currently called "luagraph.dll) for testing, please get in contact: it is a DEBUG version weighing in at about 1.5 MB. Best wishes to all Graham

Luatex 0.64.0 announcement
by Taco Hoekwater 12 Nov '10

12 Nov '10

Hi, I have just uploaded the archives for a new luatex release, 0.64.0. This is a development release, but it also fixes a few rather annoying bugs in 0.63.0. News: * New lua functions pdf.refobj(), pdf.maxobjnum() and pdf.objtype() * New lua function node.is_node() * The max_strings configuration variable's maximum value is raised to be identical to texlive's maximum (2097151), and same for param_size (32767). * The embedded mplib is now 1.503. * Minor cleanups in the output of fontloader.to_table(): - removed out-of-range altuni's from the output - don't dump the extra encodings, just the actual font encoding - export the encoding's name also as 'enc_name' at one level up - no longer exporting unset macstyles, nor zero uniqueids - fix creationtime and modification time * Ongoing work on the epdf library Bugfixes: * Fix a bug where an explicit hyphen prevented hyphenation for the whole rest of the paragraph * Internal font copying forgot to copy the last font dimen * os.selfdir() is now documented * patch quad (\fontdimen6) in \letterspacefont to be compatible with pdftex * Multi-page pdf inclusion was very slow in 0.63.0 * Some extra checks added to the handling of glue_spec node objects in lua code. * Some node.prev pointers have been corrected (but this is not quite finished). * A small fix to lpeg 0.9. The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/gf/project/luatex/ You could also check out the sources via anonymous svn: svn co http://foundry.supelec.fr/svn/luatex/tags/beta-0.64.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco
