Anyone using pymacs here? A very powerful way to program for emacs.

But there are few resources available about it. And the main site is
offline now -  http://pymacs.progiciels-bpi.ca/pymacs.html

I'm using jedi now
http://tkf.github.io/emacs-jedi/
which I like much more actually and it works very well..

That is interesting. (but doesn't work in my Emacs installation yet...)

Anyway, it is not related to my question!
"""Pymacs is a powerful tool which, once started from Emacs, allows
both-way communication between Emacs Lisp and Python."""

I use pymacs and rope, and like them quite a bit, but I remember it was
a real pain in the rear to get everything installed and talking
together. I'm on arch, so there are often confusions about python 2 vs 3
(3 is the default), and I think I was trying to install too many things
manually. Arch turned out to have readymade packages for pymacs,
python2-rope and python2-ropemode, and it all worked better.

Depending on your system, I'd definitely look for packages. Pymacs is
also available through Emacs' package manager, which might be the safest
option: install it from there, and do the usual initialization dance in
a python-mode load hook:

(autoload 'pymacs-apply "pymacs")
(autoload 'pymacs-call "pymacs")
(autoload 'pymacs-eval "pymacs" nil t)
(autoload 'pymacs-exec "pymacs" nil t)
(autoload 'pymacs-load "pymacs" nil t)

What else do you need to know?

In Ubuntu it is easy to install Pymacs because it is on the standard
repository.

The question is about passing values from python and elisp and the opposite
way.

# A function that receives a elisp variable name and returns it's value:
from pymacs import lisp
def tvar(n):
    return lisp[n].value()


AND IN ELISP:

(pymacs-load "pymacs_teste")

(setq PTEST "string")
(pymacs-teste-tvar "PTEST") ;; returns "string" Ok!

(setq PTEST (list 1 2 3))
(pymacs-teste-tvar "PTEST") ;; returns (lambda (&rest arguments)
(pymacs-apply (quote (pymacs-python . 4543)) arguments))

When python calls lisp[n].value() it returns a kind of wrapper which works
well inside python. But if I return it back to elisp, it doesn't work.

If I do instead
def tvar(n):
    return list( lisp[n].value() )

It works perfectly.

But I don't know what to do if PTEST contains a elisp symbol.

Re: pymacs

[daniel]

To put it more simple, the problem is when a python function returns a
elisp symbol back to elisp:

def teste():
    symb = lisp.simbolo
    OR symb = lisp["simbolo"]
    OR symb = lisp("'simbolo")
    #str(symb) gives " 'simbolo "
    return symb

When the function is invoked from elisp it doesn't return the symbol.

I need this for a python program that creates an emacs menu. And the menu
structure need to have these symbols that are the functions to be called
when an menu item is selected.

Ah, can't help you there, I've never done anything fancy with pymacs.
What happens when you call `pymacs-eval' on the return value from the
python function?

Doesn't work because it is not a string. It looks to be an elisp lambda
expression . But doesn't work with the elisp eval function.

I will have to use strings instead of symbols and convert then on the elisp
side.

BTW Pymacs has it's own mailing list

There's now also elpy, which allows does some of the heavy setup for you
and allows you to choose which engine you want to use (pymacs/rope or
jedi):

Re: pymacs

after installing pymacs 0.25  the problem seems to be solved

Pymacs is here:

https://github.com/pinard/Pymacs

Several programs rely on Pymacs for auto-completion.
If you don't want install Pymacs via `make' --which is the recommended way--

https://github.com/pdee/pdee

comes with an inlined Pymacs. It provides company-based auto-completion.
At an experimental state however, for experienced users/developers only.
