Loops are the one feature that I am missing in eshell. But rather than
adding the features I like to M-x shell, I'd prefer to enhance
eshell. [For purely religious reasons. I am very fond of eshell and,
moreover, I believe that the gods of editing will reward me for using
a shell that is implemented in Elisp.]
I sometimes use something like this:
(loop for f in (directory-files "." nil "\\w") do (rename-file f (concat f
"x")))
on the eshell command line.
But for the simple stuff I need, I'd prefer the sh syntax:
for i in `ls` do ...
I know how to write a simple interpreter, but unfortunately I am not
familiar with eshell's internals. And I am actually a dummy as far as
shell scripting is concerned (I tend to use Elisp for
everything). And I don't want to spend much time on it right now.
So my questions are:
1. Is it the Right Way to get this by `defun'ing a function
`eshell/for' which does the necessary parsing? The backquote stuff
would probably be a problem, but I am not sure whether eshell
actually provides a way to deal with it. Maybe I could take care
of it myself. Thoughts?
2. Where can I get (comprehensive) documentation for the sh (bourne?)
command syntax? I think, if it is feasible, I could as well make
it decent enough to be worth a patch sent to the eshell
maintainer.
