[tex-live] More trouble with TeXLive 2008 preview on Windows

[Vasile Gaburici]

Well, that's easy enough to change, but on XP one must additionally
change TEXMFHOME as well since %HOMEPATH% has spaces in it too; on
Vista %HOMEPATH% doesn't have blanks in it. I used
C:/tlhome/$USERNAME, so it would still be different for each user. (I
saw that %SystemRoot% is $SystemRoot to TeXLive, so I put $USERNAME
for %USERNAME%). But changing it in the installer wasn't enough...

C:\tlhome> luatools --generate

As you can see it keeps trying (and failing) to use "Documents and
Settings", but goes for the current directory for .texlive2008. It
looks like luatools ignores C:/texlive/2008/texmf.cnf completely.
Unfortunately that's where TEXMFHOME gets set by the installer. So, I
manually changed  C:/texlive/2008/texmf/web2c/texmf.cnf to read:

TEXMFHOME = C:/tlhome/$USERNAME
TEXMFVAR = C:/tlhome/$USERNAME/.texlive2008/texmf-var
TEXMFCONFIG = C:/tlhome/$USERNAME/.texlive2008/texmf-config

I ran luatools again, and... I got the exact same errors. Then I
changed LuaTools C:/texlive/2008/texmf/web2c/context.cnf to read
HOMETEXMF     = C:/tlhome/$USERNAME, and this helped a little since it tried:

As you can see it accesses C:/tlhome/Vasile/.texlive2008/ this time,
but it still doesn't use it; it still goes for "Documents and
Settings" to compile stuff... At this point I have no ~ in any .cnf
file (I grepped). So I looked in the .lua files. There's a bunch of
them since instead writing a single function to deal with paths and ~
substitution there's copy & pasted code everywhere. Anyway, it seem
that the problem is in lines like 'cachepath = os.getenv("TEXMFCACHE")
or os.getenv("HOME") or os.getenv("HOMEPATH") or os.getenv("TMP")'...
since os.getenv("HOMEPATH") gives "\Documents and Settings\Vasile". I
removed os.getenv("HOMEPATH") and now it goes for the next one, %TMP%,
which works:

The real bug seem that lua stuff assumes os.getenv("TEXMFCACHE") will
actually work on Windows. But it seems that setting stuff in .cnf
files doesn't set environment variables on Windows, even inside Lua.
I'll let you guys sort it out from here...


BTW, since I paid close attention to the installation this time I
noticed a couple of harmless warnings:
tar: Unknown file type '2' for
texmf-dist/doc/latex/marvosym/mac/README, extracted as normal file
tar: Unknown file type '2' for
texmf-dist/doc/latex/marvosym/vtex/README, extracted as normal file
