Text direction in PDF mode
by Wolfgang Schuster 08 Apr '08

08 Apr '08

Hi, I tried Alephs body and textdir commands with LuaTeX and the output in DVI mode is as I want (the text is written from top to bottom and left to right). The same example in PDF mode did not work, the text is written on the left side and every new line written over the first line. %\pdfoutput=1 \hsize=8cm \vsize=8cm \bodydir RTR %\pagedir RTR \pardir RTR \textdir RTR 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 \bye Greetings, Wolfgang

another stupid question ...
by Norbert Preining 06 Apr '08

06 Apr '08

... since here are so many so intelligent people ;-) On unix I can remove the current interpreter, ie I can do #!/usr/bin/perl unlink("/usr/bin/perl"); and this will succeed (if I have permissions). On windows (again) this doesn't work. I am running the uninstall program which is a texlua script but the rmdir /q ... of bin/win32 does not succeed. The texlua script is invoked via usual win32 methods, i.e. the extension .texlua is linked to the texlua interpreter, and the .texlua extension is added to the PATHEXT to be searched, and bin/win32 is in the PATH env var. Well, in the worst case we have to live with a rogue texlua.exe somewhere. Any other ideas?

writing a rmdir function in texlua
by Norbert Preining 04 Apr '08

04 Apr '08

Hi all, for the TeX Live uninstaller I am trying to write a rmdir function for win32 in texlua which should work like rm -rf on unix. My first try was: function rmdir(dirn) if os.type == 'windows' then -- we have to replace all / with \ foo = string.gsub(dirn, '/', '\\') ret = os.spawn({"rmdir", "/s", "/q", foo}) else ret = os.spawn({"rm", "-rf", dirn}) end if ret then return ret else io.stderr:write(filename..': removing '..dirn.." didn't work\n") end return ret end (No checks by now, will come later ...) But that didn't work and did spit out always the io.stderr message. Any suggestion how to do that? Or is there some code already somewhere around in the ConTeXt project? Thanks and all the best Norbert ------------------------------------------------------------------------------- Dr. Norbert Preining <preining(a)logic.at> Vienna University of Technology Debian Developer <preining(a)debian.org> Debian TeX Group gpg DSA: 0x09C5B094 fp: 14DF 2E6C 0307 BE6D AD76 A9C0 D2BF 4AA3 09C5 B094 ------------------------------------------------------------------------------- Queasy but umbowed.

Problem using umlaut in hyphenation

aleph -> luatex
by karl＠freefriends.org 31 Mar '08

31 Mar '08

The Aleph team has declared that Aleph development has been halted for some time; efforts are concentrated on luatex now. Therefore they recommend that TeX Live simply make the "aleph" executable a link to luatex. So I plan to implement that recommendation. If this is going to cause insuperable problems for anyone, tell the Aleph folks so they can convince you otherwise :). BTW, there is no plan to remove or significantly change Omega; essentially the same binary and support for Omega will be present as in past years. We (notably Akira) have already integrated the updates from Knuth's "2008 tune-up". Best, Karl

Re: [Dev-luatex] compile flags in luatex

As long as it still works for me, build issues will be way at the bottom of my todo list: I don't understand (nor like) much of autofoo, so I am lacking in the motivation department as well as in the time schedule. Meanwhile, if you (or anyone else) has the time, knowledge and motivation to help with this kind of thing, I am more-than-willing to apply patches :-) Best wishes, Taco
