Re: need help

I have been using Texmacs for a year now and I really love it.

Just downloaded the recent version and installed it in my laptop like 3 months ago. But yesterday, I accidentally pressed a key and the interface was changed,,,,and all the menus disappeared. I remember that I went to the VIEW and then HEADER and suddenly the look and feel of my texmacs interface is converted into just a plain white screen. Its hard for me to create documents because all the menus are gone. I tried right clicking but I couldnt get to the  normal interface.

I am a novice at using the Texmacs so I am coming to you for help.

Broken 'sources' link on Texmacs homepage

Dear Developers,

I wish to compile Texmacs on my Debian system. The links to sources (stable, and latest version) listed on seem to be broken. I thought I should bring this to your notice.

Thanks for an excellent piece of software!

stack overflow

This simplified macro:


gives these errors on the console when entered into the editor

.../TeXmacs/progs/kernel/library/list.scm:100:12: In expression (cdr (reverse l)):
.../TeXmacs/progs/kernel/library/list.scm:100:12: Stack overflow

the error vanishes when the first branch of the if block is removed.

I would guess it is over-optimistic reduction of the "if" statement when encountering recursion.

TeXmacs -> HTML

Hi everybody,

  I’m having some annoying problems with conversion to HTML. I’d like to use MathJAX and for that I
choose to export math with MathML. Problem is, XHTML is enforced and rendering by the browser is then
different (TeXmacs website).

Also, playing with the preferences I’ve noticed that it is possible to select contradictory options for
math formula export.

So, here’s my question / suggestion:

I’d like to create a new option “texmacs->html:math” with the possible values “html”,
“mathml”, “image”, “mathjax”.

The first three are those currently available. The idea is to disallow nonsensical settings.

The last one would include a <script> tag in the html output to use the MathJax Content Delivery Network (as
suggested here: ). It would also set MathML as the
output for mathematics, and it would *not* change the extension to .xhtml. The server would then serve the
content as text/html and rendering wouldn’t be affected.

Any ideas / objections?
Miguel de Benito.

paste verbatim interprets <tag> in red

With SVN updated just now, when I cut-n-paste some XML as text (to
show as text with all the angle-bracket glory) some of the items
appear in texmacs in red as single tokens.

e.g. if I copy this from a text editor:


and past-from-verbatim, this document fragment is produced:




which has the word <sample> in red.

I think that is not right

cleanup in color managment


I started 2 days ago a big cleanup into color managment. Code was
dramatically duplicated between Qt, x11, and converters.

Please, dont hesitates to complain about any strange behavior change,
since I cannot test all possible cases.

It remains some work on the converters side to take advantage of this,
but now it will be more easy to make the job.

As far as X11 backend is concerned, I don't know how to test it, but it
seems sure that the managment of 16 bit colors has been broken for a
long time. But I am not sure that anyone will use TeXmacs one day in
less than 2^24 colors.

OK, I downloaded the the tarball and this compiles without problem. So, I think there are some problems with
SVN trunk. Of course this don't works. But I will try to get it working. Although I have some questions, but
this is topic of other thread.

Re: [bug]input '-' in Inline code cause TeXmacs to exit immediately

sorry, I should say I set user interface language as Chinese.

[bug]input '-' in Inline code cause TeXmacs to exit immediately

I can't find a bug report mail list, so I report it here.
When I insert inline Shell code by Insert->Program->Inline
code->Shell, I input '-', then TeXmacs exits immediately. I double
checked it, found that it would not happen when I set langue as
English, but it would happen when langue is Chinese and Taiwanese.

Is CXXCAIRO used in the relevant place in src/

By the way, what do --with-axel and --with-sqlite3 mean?
