[tex-live] Strange TEXMFHOME in TeX Live 2017 on Darwin

[Yudai NAKATA]

Dear all,

I noticed that TEXMFHOME is different between TL 2016 and TL 2017
although I don’t think I configured something special when installing:

$ /usr/local/texlive/2016/bin/x86_64-darwin/kpsewhich -var-value TEXMFHOME
/Users/yudai-nkt/texmf
$ !!:s/2016/2017/
/usr/local/texlive/2017/bin/x86_64-darwin/kpsewhich -var-value TEXMFHOME
/Users/yudai-nkt/Library/texmf

TEXMFHOME in TL 2016 is same as the documentation (7th paragraph in
https://www.tug.org/texlive/doc/texlive-en/texlive-en.html#x1-260003.2.3)
and
the one in TL 2017 is like MacTeX style (please note that I use
vanilla TeX Live, not MacTeX).

As Perl is Greek to me I have no idea about what install-tl is doing,
but I found some relevant part
(line numbers are just for reference):

1393 # Environment variables and default values on UNIX:
1394 #   TEXLIVE_INSTALL_PREFIX         /usr/local/texlive   => $tex_prefix
1395 #   TEXLIVE_INSTALL_TEXDIR         $tex_prefix/2010     => $TEXDIR
1396 #   TEXLIVE_INSTALL_TEXMFSYSVAR    $TEXDIR/texmf-var
1397 #   TEXLIVE_INSTALL_TEXMFSYSCONFIG $TEXDIR/texmf-config
1398 #   TEXLIVE_INSTALL_TEXMFLOCAL     $tex_prefix/texmf-local
1399 #   TEXLIVE_INSTALL_TEXMFHOME      '$HOME/texmf'
1400 #   TEXLIVE_INSTALL_TEXMFVAR       ~/.texlive2010/texmf-var
1401 #   TEXLIVE_INSTALL_TEXMFCONFIG    ~/.texlive2010/texmf-config

1434  if (platform() =~ m/darwin/) {
1435    $texmfhome ||= "~/Library";
1436  } else {
1437    $texmfhome ||= "~";
1438  }
1439  $vars{'TEXMFHOME'} = "$texmfhome/texmf";

If I run the script, however, different default values are proposed
regarding non-systemwide directories:

$ cd /path/to/install-tl && sudo ./install-tl
[...]
<D> set directories:
   TEXDIR (the main TeX directory):
     /usr/local/texlive/2017
   TEXMFLOCAL (directory for site-wide local files):
     /usr/local/texlive/texmf-local
   TEXMFSYSVAR (directory for variable and automatically generated data):
     /usr/local/texlive/2017/texmf-var
   TEXMFSYSCONFIG (directory for local config):
     /usr/local/texlive/2017/texmf-config
   TEXMFVAR (personal directory for variable and automatically generated data):
     ~/Library/texlive/2017/texmf-var
   TEXMFCONFIG (personal directory for local config):
     ~/Library/texlive/2017/texmf-config
   TEXMFHOME (directory for user-specific files):
     ~/Library/texmf
[...]

I have no problem since I symlinked files to a new TEXMFHOME, but I’d
like to let you know just in case
(and also suppose contradiction between manual and actual behavior is confusing)

Best regards,
