TL2012 and paper config

[Norbert Preining <preining@logic.at>]

Hi Frank, hi all,

I would like to propose some changes to the paperconf stuff ...
you know I am horrible.

You did hard work to include it in texconfig, but texconfig is going
to disappear ... we don't see any use for it anyway, most things
are done in tlmgr now.

Now, there is also paper handling in tlmgr and that is much better:
$ tlmgr xdvi paper --list
a4
c4
...
$ tlmgr pdftex paper --list
a4
letter
$ 

etc etc and one can set paper size, too.

The code is quite easy, from tlmgr.pl:
  my $action = shift @ARGV;
  if ($action =~ m/^paper$/i) {  # generic paper
    my $newpaper = shift @ARGV;
    if ($opts{"list"}) {  # tlmgr paper --list => complain.
      tlwarn("tlmgr: ignoring paper setting to $newpaper with --list\n")
        if $newpaper;  # complain if they tried to set, too.
      tlwarn("tlmgr: please specify a program before paper --list, ",
             "as in: tlmgr pdftex paper --list\n");

    } elsif (!defined($newpaper)) {  # tlmgr paper => show all current sizes.
      TeXLive::TLPaper::paper_all($texmfsysconfig,undef);

    } elsif ($newpaper !~ /^(a4|letter)$/) {  # tlmgr paper junk => complain.
      $newpaper = "the empty string" if !defined($newpaper);
      tlwarn("tlmgr: expected `a4' or `letter' after paper, not $newpaper\n");

    } else { # tlmgr paper {a4|letter} => do it.
      return if !check_on_writable();
      TeXLive::TLPaper::paper_all($texmfsysconfig,$newpaper);
    }

  } else {  # program-specific paper
    my $prog = $action;     # first argument is the program to change
    my $arg = shift @ARGV;  # get "paper" argument
    if (!defined($arg) || $arg ne "paper") {
      $arg = "the empty string." if ! $arg;
      tlwarn("tlmgr: expected `paper' after $prog, not $arg\n");
      return;
    }
    # the do_paper progs check for the argument --list, so if given
    # restore it to the cmd line.
    if (@ARGV) {
      return if !check_on_writable();
    }
    unshift(@ARGV, "--list") if $opts{"list"};
    TeXLive::TLPaper::do_paper($prog,$texmfsysconfig,@ARGV);
  }

I can easily create a very simple perl script that does the same without
tlmgr, actually only the use ... statements are missing.

Would that be integrable into this?

Files are written to TEXMFCONFIG automatically

Best wishes

Norbert
