Re: [Csnd] Vim/emacs question

The process you indicated works pretty much the same way on Vim for calling
an external program, so that's a start at any rate. I'd like to make sure
the scripts can be used by folks on various editors so maybe that's the way
to go. I know there are other more integrated methods as well, such as
Pymacs for Emacs and if_Python for Vim, but I don't know much about using
them. Anyone else know?

Elisp does look worth learning, but I figure most new programmers learning
Csound probably will want to start with only one scripting language. Seems
to me Python is the natural choice there considering it's popularity with
Csound and other music language developers as well as it's ease of use and
commonality between editors.

Basically I want to make a sort of universal step event editor type thing
that one can run from Emacs or Vim, or just run the scripts seperately, to
allow easy editing of general event lists. These lists can then be exported
as Csound scores, table for my sequencer, or midi files. So the concept is
that you just have a numeric grid with time going down in steps and pfields
across. Then one can select blocks of data and transfrom or insert data
quickly from the scripts. In Cakewalk there are many handy functions that I
plan on porting, like scaling selected data by a start and end percentage,
repeating blocks, etc. I was also thinking of adding "marker" fields off to
the right of the lines that would allow you to quickly select many notes
that may not be contiguous, and leave those selections intact for the
duration of a session. So say you wanted to select only the downbeats, you
could run a function that adds your mark to all downbeats, and later run any
functions you want on all notes with that mark. When you export to Csound
score, ftable, or midi, those marks would not be used. I think that could be
used for very nice pattern generation with multiple marks and smart scaling
functions.

If anyone else is interested in these ideas we could set up a list of script
ideas  to be done and put them up somewhere. Right now I find GVim the
easiest because the mouse with Visual Block mode makes selecting blocks very
simple, but I expect that is just unfamiliarity with Emacs. Rather than join
the holy wars I think I'll just learn both.  ; )

So for now I guess I will assume the method is:
- selected data goes into a buffer/register
- script runs on data as if it is a file
- selection is automatically replaced by output from script

Feedback from those more knowledgable about this would be appreciated.
