Things like that work (rudimentarily) already for Maple and Octave in 1.2.0. The missing Mathematica support results mainly from me not being able to get Mma up and running on my Linux box. I have a licenced copy in reach and it looks as though it contains a Windows and Solaris version on the CDs but failed to install it on Linux (can't remember what went wrong exactly). > So, where can find the list with explanations of the lyx's commands.

How about adding support to Maxima, which is GPL (unlike Maple/Mathematica) ? Another free CAS is MuPAD, but it is not open source.

Yes, but how it work? And what exactly can be done? I'm interested to add mathematica support but I'd like have more information about what has been already done. I had a look at the files src/mathed/math_extern.[Ch] but as I don't know what I'm looking for, it doesn't realy help. > > So, where can find the list with explanations of the lyx's commands.

You write '1 + 2' in a math formula and type 'M-x math-extern maple simplify' to get a '= 3' added. Alternately, you can mark the '1 + 2' and it will get replaced by '3'. In general, 'M-x math-extern foo' will call Maple's 'foo' function on the selected expressin. > I'm interested to add mathematica support but I'd like have more > information about what has been already done.

You basically have to add a function 'mathematicize' (or whatever) to every math inset (or at least to the ones you are interested in) and there you put code to transform the inset into Mma syntax. Usually you should be able to copy the 'maplize' function and replace parantheses by square brackets and things like that. Than you need to have a look add math_extern.C and formulabase.C and hook calls to these new functions in. You need to call Mma in some kind of command line mode that produces minimal output (either a result it LaTeX or an error message) and parse this output. Just look at what the maple and octave backends do. It's not exactly rocket science but quite a bit of work.

It is not very nice to have this hardcoded in the LyX sources. can't you do it in external scripts, like the first implementation ? Another idea would be to use text template files. For example, an extern_maple would be something like Insets frac ($0)/($1) sqrt sqrt($0) ... End Header readlib(latex): latex/csname_font := `: ... End

But I think I'll do something like that myself some day when the math-extern stuff has reached some critical mass that allows me to see what is a "generic common base" and can be used as the hard-coded part, and what is "backend specific" that could be put in such configuration files.

Ok, for the moment, I'll try to implement the mathematica stuff with the old fashion. I'll have time to do that this week-end. I suppose I have to start with the cvs version. geof -- ~ 'v'mailto: gpiroux_at_mac_dot_com // \\ Powered by GNU/Linux-ppc /( )\ http://lfs.linux-provider.net/ #112 ^'^
