ConTeXt installtion and Debian

ConTeXt installtion and Debian

[Norbert Preining]

Hi Taco, hi all!

(I am sending personal copies since I don't know whether I can mail to
the ntg list).

First of all thanks for the explanations!

I checked the current zip file and the current ctxtools.rb script, it
does nothing else than:
- download the current zip
- unpack
- install the stubs from scripts/context/stubs/*
- update the formats.


So this is what we have to do in the Debian package, too. This is not
hard, in fact most parts are already done. The only thing we have to do
is create a way for the user to choose which formats should be
generated. I will think about this.

But for the search pathes, we will adjust the Debian texmf.cnf file, to
get different engines loading differen cont-en.fmt files. Thanks.

Best wishes

Norbert

Hi Taco, hi all!

I am trying to fix all the problems for Debian ...

Another thing Taco wrote was:

This change I have executed in the tex-common depot, it will not hurt
anybody.

Debian currently has:
TEXFONTMAPS = .;$TEXMF/{fonts/,}map//;$TEXMF/dvips//

What about this? I am not completely convinced about it since with
updmap we generate input file for all the different programs.

For Taco: I have NOT installed the dvipdfm map files, only those from
fonts/map/pdftex/context and fonts/map/dvips/context

Furthermore I have added all the maps in fonts/map/dvips/context to the
updmap config file and called updmap-sys.

So now I can call texexec on several documents without any problems and
all the fonts are found.

What is the problem with
- removing the dvipdfm maps
- generating lines for dvipdfm(x), pdfetex, dvips from the dvips config
  files as done by updmap-sys

It would be great if we could straighten this out and get nice packages
for Debian rather soon.

Best wishes

Norbert

The second part, $TEXMF/dvips//, is a Debian-specific
backwards-compatibility hack to allow fonts to be found that install
their map files according to the old (teTeX 2.0) TDS.  We should drop it
as soon as etch is out, and we should probably have done that even
earlier.   The first I don't quite understand, we actually have:

% TEXFONTMAPS = .;$TEXMF/{fonts/map,}/{$progname,pdftex,dvips,}//
TEXFONTMAPS = .;$TEXMF/{fonts/,}map//;$TEXMF/dvips//

This looks like we dropped the program-specific paths (and with that
their order), and like it wouldn't have been necessary to add a hack
(but I know that at the time of the teTex-3.0-beta-release when I
introduced it it *was* necessary).

one may assume that by now indeed most trees are tds compliant

the first (commented) one is indeed the one that is needed in order to 
let dvipdfmx work nicely (even more important now that xetex uses 
dvipdfmx as backend)

this should be ok for todays situation 

is better since it permits installation of fonts without the need for updmap magic (and side effects); maybe at some point in the future there will be a common map syntax (side product of pdftex project) which will make live easier

Ok, I have rewritten the Debian context package so that it does the
following:

On installation/update time a script context-build-formats is called
which reads the file
	/etc/texmf/context/formats.cnf
where all the formats to be build are defined. Currently my file looks
like this:
#
# This file defines which ConTeXt formats are build
#
{pdftex,aleph} {de,en,it,mptopdf}

Yes, it expands the curly braces.

On removal currently I don't do anything, because I don't know how to
know which files should be removed. But this shouldn't be to hard,
remove /usr/share/texmf/web2c/$engine/$format.*

Anyway, it is not very intellignet the script, no error checking,
nothing, but it runs.

What do you say:
- you ConTeXt people: concerning the format file, the way of updating?
- you Debian people: concerning the new way to define it?


The context-build-formats should be something like fmtutil(-sys) for
context. I didn't come around to implement the difference between the
-sys and the normal variant, but it should be easy, as in fmtutil-sys.

Any suggestions?

BTW, here is the code for the script, it is short:
#!/bin/bash
# context-build-formats
export TEXMFSYSCONFIG=/usr/share/texmf

parse_line()
{
  engine=$1
  format=$2
  eval set $engine
  allengines="$@"
  eval set $format
  allformats="$@"
  for e in $allengines ; do
    for f in $allformats ; do
      texexec --make --$e $f
    done
  done
}

OIFS=$IFS
IFS='
'
set $(echo x; sed '/^#/d; /^[  ]*$/d' "/etc/texmf/context/formats.cnf")
; shift
IFS=$OIFS
for line 
do
  parse_line $line;
done
# eof

You see where I robbed the code ... fmtutil.


Best wishes

Norbert

Minor point: /etc/texmf is a TEXMF tree that IMHO should follow TDS,
hence
           /etc/texmf/tex/context/formats.cnf
might be more appropriate.

Really /usr/share? To which tree are format files written?

Why that? (Probably related to the question to which tree format files
are written.)

it depends a bit, data and configuration files go under /tex/context, 
but you're right about a missing path part, it probably should be

etc/texmf/context/config/formats.cnf
