some patches

[Hans Hagen]

Hi,

I played a bit with texmfstart on the (so so slooooow Q3) mac and i 
think that i managed to get texmfstart working with less problems. I now 
also ship a texmfstart with all the used (context/ruby/base) libraries 
merged in (new undocumented feature) so that there is no longer a need 
to set the ruby lib path and/or move base files.

The new version is uploaded. A next step is to get the stubs done in the 
right way (just texmfstart scriptname args)

(btw, is there a clever way to avoid this sudo stuff and become real root?)

Hans

I personnaly do:

    sudo -s

when I need to become root for several commands. And then I:

     exit

Ubuntu Linux also uses sudo instead of a root login.  There I get
around it with:

$ sudo bash (or your favorite shell)
Password: ...
# cmd1
...

Not quite related to this subject, but as you are going to make the  
ConTeXt
installation more and more robust. It would be nice if the ConTeXt  
independant
distrib could be use **without positionning any TEXMF like variables**.
This would allow to use updated ConTeXt distrib without breaking a  
standard
(more or less old) other LaTeX existing distibution.

hm, in principle you can put the minimal over an existing big one and cross your fingers for it to work. 

the problem with the texmf vars's is that some of them are hard coded (sigh) and the reason why i provide the 'setuptex' things is that when i install tex on some system, i want to be sure that there are no interferences (in the past tex was often installed on linxu systems by default and the only robust way to get rid of an exiting setup was to overload all relevant texmf related vars; 

btw, a inimal installation will not break anything exiting, since you can put it somewhere else; you can even get away from the setuptex scripts by running 

texmfstart --tree=/say/its/located/here texexec ... 

which is handy in web based environments; in that case, texmfstart will read the setuptex.tmf file

It is up to you to decide when to call "setuptex", so you can
control this already. Or do I misunderstand something?

This depends on what you want to do and on which system. On most  
unixes, you can say. You can in perl (and probably also ruby which I  
do not know) set all kinds of unixy things like real uid ($<) and  
effective uid ($>) as long as you already have the permissions.

	sudo -H -s

to become root and also have root's home directory.

i think i missed why you need to become root.
is this for regular runs of context in the future?

Thank you very much.
So I can do a little "texexec" script, add its path in front of the  
global
path (so that it will be found before any standard old ConTeXt distrib)
and use the new "texexec" shell script as the main context executable  
as usualy.


The main avantage over my previous proposal is that it doesn't even  
require
adding a new path in the PATH environment variable (which already is  
quite
accectable!).

Yes, but the texmf-local is part of a particular directory from a  
particular network
or host. And I like to separate my own (full, independant,  
robust, ...) ConTeXt
environmement from the several LaTeX distrib I use
(e.g. my unix/osX account is mirror via rsync between hom, work, and  
another network.

No, because of recent font (lm) probleme, I decided to keep a full  
context
distrib (linuxtex.zip + macosxtex.zip + justtex.zip) in my personnal  
home
directory.
I positionned this environment with some "setuptex" variante before  
using
context program (with all previous problems when comming back to LaTeX)

Do you mean that "texexec.rb" is clever enought to guess its ows  
directory tree ?
Great, that what I asked for ;-)
(and if "texexec.rb"" becomme the standard texexec tool the problem  
is solved
(no more need to do a small texexec" shell script) but...
... for context programme only, but what about other tools (metapost,  
mp2pdf...)

Ok, I can always make an alias "ctx" for "texmfstart --tree=..."

	alias ctx=texmfstart --tree=/home/myHome/myLocl/fullcontext

perhaps it solves all problem at a time!
I'll try that in the next two week.

Thank you very much,
