I would recommend looking at existing languages which are similar to the new language for guidance/examples. In the case of GRASS, it sounds as though GRASS is a sub[super]-set of R? No - GRASS can be described as a collection of commands which are executed in the shell after some environmental variables are set. So GRASS is rather a super set of a bash shell. So an implementation of GRASS could easily build on how sh code blocks are hab=ndled in org. Interactive GRASS sessions are effectively sh sessions with adapted $PATH variable and a few environmental variables, to make the GRASS commands accessible. So really the easiest would be to use the existing sh support, set the environmental variables, set the $PATH and execute the commands. The environmental variables could be defined in :var - so actually that should not be a problem. Syntax highlighting could be based on sh with added commands in the added $PATH - should not be to difficult (theoretically...). Would it be possible to simply use the existing R support in babel only specify a non-R command to be run to start interactive sessions? Well - R, like python which is becoming the official scripting language for GRASS, has a set of commands to interface with GRASS - so using R (or python) would not be a useful approach. There is an R package (spGRASS6) which is doing exactly what I mentioned above (setting the $PATH and the environmental variables) to be able to execute grass commands from within R - (with the syntax execGRASS( COMMAND, ... ) So one could look at that command (initGRASS() I think it is called) to see what is necessary - or just execute grass: grass -text GISBASE/LOCATION_NAME/MAPSET ## rkrug@ecolmod:~/deb$ grass --help Usage: grass64 [-h | -help | --help] [-v | --version] [-c] [-text | -gui | -tcltk | -oldtcltk | -wxpython | -wx] [[[GISDBASE/]LOCATION_NAME/]MAPSET] Flags: -h or -help or --help print this help message -v or --versionshow version information and exit -c create given mapset if it doesn't exist -text use text based interface and set as default -gui use graphical user interface (wxpython by default) and set as default -tcltk use Tcl/Tk based graphical user interface and set as default -oldtcltk use old Tcl/Tk based graphical user interface and set as default -wxpython or -wx use wxPython based graphical user interface and set as default Parameters: GISDBASE initial database (path to GIS data) LOCATION_NAME initial location MAPSET initial mapset GISDBASE/LOCATION_NAME/MAPSET fully qualified initial mapset directory Environment variables relevant for startup: GRASS_GUI select GUI (text, gui, tcltk, oldtcltk, wxpython) GRASS_TCLSHset tclsh shell name to override 'tclsh' GRASS_WISH set wish shell name to override 'wish' GRASS_HTML_BROWSER set html web browser for help pages GRASS_ADDON_PATH set additional path(s) to local GRASS modules GRASS_BATCH_JOBshell script to be processed as batch job GRASS_PYTHON set python shell name to override 'python' rkrug@ecolmod:~/deb$ ## So it should be doable relatively easily I guess. So the environmental variables needed would be: GISDBASEinitial database (path to GIS data) LOCATION_NAME initial location MAPSET initial mapset So that GRASS can build GISDBASE/LOCATION_NAME/MAPSET fully qualified initial mapset directory Thinking of it, a GRASS code block #+begin_src grass ... #+end_src would be a sh code block, in which as the first command grass -text is executed, i.e. #+begin_src grass grass -text ... #+end_src For tangling: GRASS scripts are executed usually from within GRASS, so they are normal sh scripts (same shebang and all) So implementation should be rather straight forward, I think? Just a side note: as GRASS installs in addition to the command grass also a command grass64 for version 6.4 etc, it would be nice to have the command grass modifiable.

GRASS GIS As far as I know there is no grass-mode in emacs, but some expert people are successful running grass processes together with R processes in ESS. Since GRASS and R are natural allies, it would be great to use the GRASS engine in an org-file to retrieve spatial data and then analyse the data with R in the same file - would make Org a kind of emacs-grassmode replacement. I second that - but what would be really needed to make this work nicely, is syntax highlighting for grass commands. And in addition, GRASS scripts are shell scripts - so one should be able to use a combination of :session and sh code blocks to run GRASS commands without problems (haven't tried it yet, but nice idea). The only question would be on how can I start a shell, in which I start GRASS in which I run the R shell? Well - what I did was to start GRASS in xterm, in GRASS start emacs with and when I started R in emacs, it was running in GRASS. Is this what you mean, or am I missing here something? Rainer 2.
