[Peter Rapcan <address@hidden>]

Dear Max,

What is the location of the math.c are you referring to?

Also, in case I need to download the source and compile the TeXmacs.app for OS X, is there some step by step guide how to proceed?

Best,

-Peter.

You can add some setenv() invocations in the main() function of math.c in order to reproduce the relevant environment variable you see in a terminal shell via “printenv”

I will second that advice.

My hunch is that your $PATH variable contains a reference to Mathematica, and the TeXmacs app is waiting to establish a pipe to a process that doesn't exist (without the path, Mathematica can't launch). That shows up as busy.

Could be wrong. Please check.

Thanks guys. Is there a way to list the variables available/set in both situations to compare (or some other way to find which variable value is missing)? Once the variable is identified, what needs to be done to the TeXmacs.app package to set the missing variable?

Cheers,

Peter.

I also would guess this is the reason.

That is a potentially important clue.

When an app is launched from the bash shell, it inherits the environment variables set in that shell.

Possibly, a needed shell variable is undefined when you launch the app through GUI.

Replying to my own post:

Strangely, if I run TeXmacs from the Terminal.app (executing /Applications/TeXmacs.app/Contents/MacOS/TeXmacs), the Mathematica plugin works! However, when TeXmacs is launched by clicking via the app icon, the plugin only displays a “busy” message on any computation…

What could be the reason for / solution to this?

Cheers,

Peter.

Hi Madhusudan,

Thanks for your reply. I am referring to the script you posted to the texmacs-users list on 18.02.2011 which, as you reported back then, partially worked on the Mac OS X 10.6.6 with Mathematica 7.0. The problem you were stuck at at the time is not present anymore (at least not on my system) and I altered your script so that it works with the Mathematica 10 and OS X 10.11 (though breaking functionality on Mac OS X 10.6 and Mathematica prior to v 9).

If someone helps me to get the Mathematica plugin to work properly for me, I am then willing to try to check functionality / make it work properly with Mathematica 8 and 9 too (and perhaps also OS X 10.6) as I have those installed on some of my computers.

It would be great to have a properly working Mathematica plugin on reasonably new versions of OS X (perhaps 10.6.8 or newer), Mathematica (perhaps v6 and newer) and Texmacs, ideally with autodetection of versions. I am willing to do some testing on the systems I have (and even install older ones if necessary) but someone would have to lead / help with an approach to properly detect versions of the software involved (I am not a programmer and I don’t really have the time to learn this stuff from scratch by myself).

I agree the official updates of TeXmacs are seldom, but AFAIK there is always some development in the svn. Developers, could there perhaps be nightly (or some longer-period-based) builds for all the supported platforms that users could use/test between releases without having to set up/learn how to build from svn themselves? With regard to OS X compliance, AFAIK there used to be a cocoa version in development, but I guess it is too time consuming to maintain both QT and cocoa version.

As for journals' support, export to latex works reasonably well, and writing a (physics) paper in TeXmacs vs. TeX is like heaven vs. hell ;-).

Cheers, 

Peter.

Not sure which of my scripts this refers to, but it has been years since I used TeXmacs because of the slow updates (especially on Mac), lack of closer compliance to OSX GUI, and the lack of interest from journals to have separate templates for TeXmacs.

I am not sure from which version of Mathematica on, the old functions cannot be used; in any case I could not compile the tm_mathematica.c with the libMLi3.a choice without these changes in the case of  Mathematica 10.0.0.0). I suppose these changes need to be done also if one wanted to use the stock tm_mathematica.c provided in a TeXmacs installation.

The wrapper is attached. (note that creating a symlink to MathKernel does not work). After doing this, TeXmacs offers the Mathematica session in its list of supported sessions.

Unfortunatelly, the session does not return results of computations; instead it shows a “busy…” message (see the attached screenshot).
