I think that this discussion could be of interest for the community. I wrote last year ( http://lists.wfu.edu/pipermail/gretl-users/2011-November/006995.html ) about the creation of a Gretl mode for ESS <http://ess.r-project.org/>(there is already a R, Stata and SAS mode) but didn't ask directly to the ESS developper. This year, I asked them directly and they seems open and I think that It will be a great opportunity for Gretl to reach another type of users But if you have additional information (community size, relevance to create this mode, etc) to help in this process it'll be great Ahmadou ---------- Forwarded message ---------- From: Vitalie Spinu <spinuvit(a)gmail.com&gt; Date: Sun, Sep 30, 2012 at 10:00 PM Subject: Re: [ESS] Gretl mode for ESS To: ahmadou dicko <dicko.ahmadou(a)gmail.com&gt; Cc: ess-help(a)r-project.org mode I have never heard of gretl. How big is the community? And how does it compare to R, ox and eviews? http://fossies.org/unix/misc/gretl-1.9.9.tar.gz:a/gretl-1.9.9/utils/emacs... It's not that difficult to add a new interaction mode to ESS. The main problem is not with adding a mode, but rather with maintaining it latter on. I can look into it, but not earlier than in a couple of months time. You can look into it yourself. Sources for inspiration are ess-julia.el, which you probably should start with, and also ess-r-d.el for a more complete picture. Once the editing mode is there, the main step is to construct ess-gretl-customize-alist with all the defaults needed for the interaction with the subprocess, and then write 'gretl function for starting a subprocess.
