I think that I fixed the bug in SVN revision 8243.
It will be in the 1.99.2 release.

Two short tests:

1) TeXmacs-1.99.1-x11-i386-pc-linux-gnu from http://www.texmacs.org/

<\unfolded-io|Scheme] >

<\input|Scheme] >

2) TeXmacs from openSUSE repository

Scheme] (version)


Did I test the correct revision? TeXmacs from openSUSE repository works perfectly.

There is an update to TeXmacs version for openSUSE 13.1 available. All problems disappeared.

A simple work around is to write a "copy" of filter and add it to
tmtex.scm and latex-tools.tm

I installed TeXmacs version 1.99.1 on a fresh machine with openSUSE 13.1. with the generic rpm package and made 3 tests.

1) neither guile 1.6 no 1.8 are installed are installed, same error.

2) guile 1.8 is installed, same error.

3) guile 1.8 and 2.0 are installed, same error.

In addition I made the following observations:

1) The work around with "list-filter" causes another error:

/usr/share/TeXmacs/progs/kernel/library/list.scm:233:19: In procedure car in expression (car l):
/usr/share/TeXmacs/progs/kernel/library/list.scm:233:19: Wrong type argument in position 1: #<procedure #f (#{\ g10}#)>

2) If I start a scheme session in TeXmacs version 1.99.1, same error, but no error with the old version version

It seems that the (wonderful) "filter" function is not defined in the core of old guile releases, like 1.6.

I will make the needed changes to handle this bug.

As a temporary workaround, you could make one of the two things:

  • update to Guile-1.8 (not Guile-2.0!)
  • or, replace "filter" by "list-filter" in the file

/usr/share/TeXmacs/progs/convert/latex/tmtex.scm line 471.

Thank you for the attachments. Unfortunately, I don't reproduce the bug.

Could you tell me please the output of:
$ guile --version

This is strange, since filter is a primitive guile function.

Could you please attach a document reproducing this bug? (Or, if you don't want to publish it, can you sent it please at fpoulain at metrodore dot fr ?)

Thanks for helping TeXmacs.
