Hello,

the idea of having two packages, one containing the data and invisible to 
the user, and one containing the binaries and depending on the data did not 
work: The binaries need to create an index of the data that is stored in 
the data directory, but a package has no write rights in another one, which 
is coherent with the functional approach of guix.

So I ended up creating one package with two outputs, "out" and "share"; the 
user just installs the main package and has no reason to touch the "share" 
part (which would not do any harm, either: installing it would create 
100000 unused symlinks in the user profile...). Just in case you wonder, 
the "out" part contains the man and info pages in a subdirectory named 
"share", while the "share" part contains three subdirectories not named 
"share". The file is attached, and nitpicking is welcome. (Caveat: As said 
before, there are 1.5GB to download, and about 3GB to install, plus the 
same during unpacking.)

Concerning the license, there is not only one, see
   http://www.tug.org/texlive/copying.html .
But everything is FSF and Debian free. How about adding a license "mixed" 
or "fsf-free"? Or do you have a good suggestion?

Andreas

PS: So that I can fully drop my Debian packages, now we only need X.org to 
enable xdvi ;-)

OK.  So the catalogs are built once for all during the build, right?

Perhaps “data” would be a (slightly) more descriptive name?

Looks like your approach works fine, but maybe we could still ask Karl
Berry to see what he thinks?

I’ll try once I have real network access.  :-)

Yes, or we could just export the ‘license’ constructor from (guix
licenses).  That would allow us to make a custom <license> objects when
needed, like here.

And the good thing is that now that you’ve done TeX Live and netpbm,
you’ll find that Xorg is really piece of cake.  :-)

Some nitpicking, since you asked:  ;-)

Could you maybe move 'install to the next line, aligned with the ‘a’ of
‘alist-cons-after’?  (Otherwise Emacs/Paredit will mess up with the
indentation since it would do it like that.)

Rather:

  (with-directory-excursion bin
    (for-each symlink
              '("pdftex" "pdftex" "xetex" "luatex" "luatex.1")
              '("latex" "pdflatex" "xelatex" "lualatex" "lualatex.1")))

When you have paired ‘cd foo’ and ‘cd ..’, you can instead use
‘with-directory-excursion’, as shown above.

Likewise.

Looks like the ‘display’ calls are debugging output that could be
removed?

If you want to keep them, write it like:

  (format #t "PATH set to `~a'~%" (getenv "PATH"))

Other than that, impressive work, Sir!

Yes, over the full content of the texlive distribution.

Okay, why not; I used "share" because normally the subdirectories end up in 
"share".

Or we could leave it empty in some way; just call it "free"? It is clear 
that we will only package free software; so a license field that can only 
state "a collection of free licenses, for details, see the source" conveys 
really no information at all. So I do not see what to construct here. My 
suggestion:

(define fsf
  (license "fsf"
           "http://www.gnu.org/licenses/"
           "A collection of free licenses according to the FSF, see the 
source for details."))

> And the good thing is that now that you’ve done TeX Live and netpbm,

After looking at it, my impression is that at least the build process 
should be much easier (once the right order of installation determined).

There is one edition per year, commonly refered to as "TeX Live 20YY"; so 
there is no reason to go into more datails.

Very elegant, thanks for the suggestion! But actually, this manual symlink 
phase has become superfluous by some directoty related configure flags I 
just added.

Okay. Here it is less useful, since "unpack" changes directories, so a 
"chdir ".."" will remain in any case.

Sorry, I was mixing things up; my comment refers to another place, so this

Well, for licenses that we fail to classify, I think we should at least
provide a URL or file name to look at, along with an indication of
whether it’s copyleft.

Similar to ‘bsd-style’, what about adding:

  (define (copyleft url #:optional (comment "")) ...)
  (define (fsf-free url #:optional (comment "")) ...)

For TeX Live, we’d use

  (fsf-free "http://tug.org/texlive/copying.html")

WDYT?

OK (I was wondering because the tarball name contains additional digits.)

Not sure if we need two of them. Is the attached patch okay?

Hello,

attached what I think could be the final version, once the license question 
is decided.

While looking for mirrors at
<http://tug.org/texlive/acquire-netinstall.html>, I noticed that mirrors
usually have a slightly older version–e.g.,
<http://osl.ugr.es/CTAN/systems/texlive/Source/texlive-20120628-source.tar.xz>.

Perhaps we should just stick to tug.org.

Hello,

the attached patch does what its commit message says. It is the fruit of many
trials and discussions with Ludovic. The tricky thing was to link to the
kpsewhich binary in texlive-bin, but to make it take its configuration file
texmf.cnf from texlive-data. I ended up wrapping all binaries and providing
them with the suitable value of TEXMFCNF.

The real goal of the patch is to make it easy to create a second package
texlive-small in a second step. This package shall inherit from texlive,
but have as input texlive-texmf-small, which is created as texlive-texmf,
but after deleting a big chunk of data; I would say, all the documentation
and most of the fonts. Such a smaller package could be a native input for
packages creating their documentation from a latex source, for instance.

Andreas

From: Andreas Enge <andreas@enge.fr>

Subject: [PATCH] gnu: texlive: Make the package structure more modular.

* gnu/packages/texlive.scm (texlive-bin, texlive-texmf): New variables.
  The first one contains the binaries; the second one the texmf tree.
  (texlive): Drop output "data". Create the output "out" as the union
  of the suitable subdirectories of texlive-bin and texlive-texmf, and
  wrap the binaries, setting TEXMFCNF to the value corresponding to
  texlive-texmf.

I'm use latex in some presentation and academic area. But there're some 
much dependencies in Texlive, I have install it but your size is bigger 
(2gb+-), the texlive-small is a great idea. Usualy I'm use pdflatex and 
bibtex to some references, I like bemmer too.
There're a lout package, is smallest that livetext, but there're some 
much papers in academic that use latex :(
I use lout in some presentation and other.

What is the rationale for this change?

Contrary to what one might expect based on the names of those procedures
and the frequent pattern

  (or (%current-target-system) (%current-system))

(%current-target-system) returns a GNU triplet whereas (%current-system)
returns a Nix system.  A GNU triplet for MIPS64 will start with "mips64"
but is unlikely to be "mips64el-linux".

None. I see you made a change on January 6. I have been working on texlive
before, so probably things merged strangely.

Thanks for spotting this!

I don’t want to spoil the party ;-), but could it be that there are
programs outside of TeX Live that use libkpathsea & co.?

Theoretically yes, but practically I do not think so.

If I understand correctly then the two packages, texlive and
texlive-small, will essentially be independent.

It would be nice to have an incremental strategy with a hierarchy, say
texlive-base, texlive-common, texlive-extra, texlive-all, where each
package is non-overlapping with other ones. Then a new functionality to
aggregate packages into a new package where you specify which packages
to include. Something like

guix package --aggregate texlive --with texlive-base texlive-common ...

This would be useful for packages with plug-ins, to bundle compilers with
a selection of libraries, ...

Yes, and mutually exclusive: If you install both, then there will be lots
of collisions with an unpredictable outcome.

I agree, but did not find a way of doing it. The problem with texlive is
that part of the aggregation takes place in the install location (which for
us would be the store).

For instance, "mktexlsr" creates a file
  /gnu/store/pvhfl19r2v7fn00g45jkv32n211bk90h-texlive-2014/share/texmf-dist/ls-R
(after applying the patch), which contains the result of running "ls -R"
inside the directory. This could be done inside the user profile, but not
with the current setup, where
  $HOME/.guix-profile/share/texmf-dist is a link to the store directory
(which is a useful feature we added at some point in time, since it avoids
the need for symlinking the thousands of files inside this directory tree),
so that the ls-R file would be tried to be created in the store.

Then there are the calls to updmap-sys and fmtutil-sys, which I did not
look at in more detail. The latter seems to create files
texmf-var/web2c/*.fmt; it may be possible to create them by chunks and to
merge them in the profile (and then do the "ls -R"-business).

In non-functional (:-)) distributions, the problem is solved by recreating
a global configuration upon installation of an additional package.

So there may be better ways, and anybody is welcome to look into them!
My patch makes a first step by separating things better.

Just to clarify: the idea would be that the "--aggregate" command
would produce a new package in the store. The new in store package
would inherit the content of the "--with" packages, but with the
possibility to replace some parts (e.g. ls-R, ...) with the help of
some phase. The new parts would only be residing in the new aggregate
and the user would install the new aggregate instead of the other
individual parts.

I understand that this is currently not possible, but, from my point
of view, would be useful functionality for the future.

I see. As mentioned by Ludovic, this seems like a big hammer to solve a
smallish problem. Something easier could be done in the texlive module
already. I considered something along the following lines:
- Write a procedure that takes a (possibly empty) list of subdirectories to
  delete from texlive-texmf, and that returns the corresponding package.
  For the current texlive-texmf, one would pass an empty list, for
  texlive-texmf-small, it could be a list containing "doc", for instance.
- Write a procedure that takes a texlive-texmf type input and creates
  a corresponding texlive package, and use it for texlive and texlive-small.
This would be theoretically very flexible, but I think we want to limit the
number of texlive packages exposed to the public; personally, I would say
to two...

I think the problem here is really that TeX Live is monolithic, and I
don’t think that should be addressed by the packaging tools themselves.

My 2¢,

The main TeX Live installer may make it look like it is monolithic,
but it isn't monolithic at all. It is very configurable and every user
can add his own classes, fonts, packages, ... wherever he wants even
using central installations on traditional UNIX systems. TeX Live has
its own management tool 'tlmgr', but underneath it makes use of
established Web2C tools.

As one example, setting
export TEXINPUTS=~/.guix-profile/share/texmf:

all the files in the personal profile would be found (on top of the
ones in the central installation configuration files). You can even
specify if you want to make use of files databases (ls-R), or not (and
that for each directory tree individually). See, e.g.,

http://tug.org/texlive/doc/texlive-en/texlive-en.html#x1-540007

Making the various TeX tools find components (classes, fonts, ...) in
"extra" store locations may be tricky, but making it find them once
installed in a user profile should be easy.

Maybe finding files in "extra" store directories could be achieved by
making use of variables expansion, something like
"!!/gnu/store//share/texmf" (note the double slash and exclamation
marks), in the central configuration file. (See above document.)

I think that working out the proper way to install it on Guix may be
tricky, but, given the flexibility, a good hierarchical solution
should be possible.

OK, interesting.

IMO the ideal would have to have it split into a bunch of packages or
package outputs, like “core”, “doc”, “extra.”  Ideally, users could
choose to install 1, 2, or 3 of these and things would just work.

I’m not really knowledgeable but that seemed extremely difficult to
achieve (Andreas might want to share his sufferings ;-)).  Part of the
reason is that there’s no simple search path mechanism, and instead
something sophisticated that includes texmf.cnf and a couple of
libraries and commands to deal with search paths.

The latter prevents the addition of a “doc” output, for instance,
because the ‘texdoc’ command (in “out”) needs to refer to the “doc”
output, and vice versa (there cannot be circular references among
outputs of a derivation.)

Anyway, I think everyone would love a better solution, so if you have
ideas, do not hesitate.  :-)

Thanks,
Ludo’.
