Re: [NTG-context] texmfstart newbie

OK,

I've updated to the latest context via Gerben's i-installer on my mac osx 10.4.6.

I have no idea what texmfstart is nor do I understand its purpose.

I imagine the first thing I have to do is configure, because it is certainly not found on my system.

tmp $ which texmfstart tmp $ texmfstart -bash: texmfstart: command not found

Here is my path:

tmp $ echo $PATH /sw/bin:/sw/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/ local/teTeX/bin/powerpc-apple-darwin-current:/opt/local/bin:/usr/ local/mysql/bin:/usr/X11R6/bin

For example:

tmp $ texexec --version

TeXExec 5.4.3 - ConTeXt / PRAGMA ADE 1997-2005

texexec : TeXExec 5.4.3 - ConTeXt / PRAGMA ADE 1997-2005 texutil : TeXUtil 9.0.1 - ConTeXt / PRAGMA ADE 1992-2006 tex : pdfeTeX, 3.141592-1.30.4-2.2 (Web2C 7.5.5) context : ver: 2006.06.23 20:39 cont-en : ver: 2006.06.23 20:39 fmt: 2006.6.27 mes: english cont-nl : ver: 2006.06.23 20:39 fmt: 2006.6.27 mes: dutch

warning : use 'texmfstart texexec' instead

tmp $ which texexec /usr/local/teTeX/bin/powerpc-apple-darwin-current/texexec

Which appears to be some sort of shell script.

Yes, it is a wrapper that uses kpsewhch to search for <what>.pl and then fires up perl with the full path to the script. The same trick works for ruby (.rb) and java (.jar). I've made 3 scripts, called runtexmfXX, where XX={pl,rb,jar}: ----------------- runtexmfrb ---------------- #! /bin/sh # runtexmfrb -- run ruby scripts with "ruby <path>texmfstart.rb .." # Author: George N.

Ruby is installed:

tmp $ which ruby /usr/bin/ruby tmp $ ruby --version ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]

And here is the location of texmfstart:

/usr/local/teTeX/share/texmf.local/scripts/context/ruby/texmfstart.rb /usr/local/teTeX/share/texmf.local/scripts/context/stubs/lib/texmfstart /usr/local/teTeX/share/texmf.local/scripts/context/stubs/lib/ texmfstart/base /usr/local/teTeX/share/texmf.local/scripts/context/stubs/lib/ texmfstart/base/kpse

Now for questions:

1. How do I configure my system to use texmstart?

in the "bin" directory with texexec, rename texexec to texexec.orig, create the 2 or 3 scripts you want to use, do "chmod +x runtexmf*", and decide which names are perl (.pl) and which are ruby (.rb). Create symbolic links: "ln -s runtexmfrb texmfstart", etc. for the ruby scripts. You can also do this for other perl scripts such as epstopdf, but be careful, as the bin directory may contain newer versions than the texmf trees.

2. What are some of the usual uses I should be employing of texmfstart? How will it improve performance? How will it simplify my work? Etc? I.e what are the advantages?

Performance for scripts like this is not much af an issue these days -- if you want performance, buy better hardware. What is an issue is the ability of the developers to find and fix bugs. Perl is old and tricky. There are lots of old buggy perl versions installed. Hopefully ruby will turn out to be more robust (lessons learned, etc.). The advantages to us are that you will use it and report bugs before we do. The advantages to you are that Hans is replacing perl scripts with ruby scripts, so if you need a new feature it is more likely to appear as ruby than as perl code. -- George N.
