Re: Emacs mode can't run pil

[Lawrence Bottorff]

 . . . yes, sessions
make perfect sense, but I thought sessions was an advanced feature for only
some of the "elite" languages, i.e., so many of the babel languages don't
support sessions. Still, I should have known to try. . .

Now, why would trying to run picolisp (org-mode or picolisp-mode) from an
Emacs started with emacsclient -c -a '' from my Gnome taskbar not work? It
gives the error in my Messages:

executing Picolisp code block...
executing Picolisp source code block
(New file)
Wrote /home/hercynian/.pil/editor
apply: Searching for program: No such file or directory, pil

and it writes `editor-orig` to ~/.pil, which I must then rm. I can only get
a REPL when I start Emacs from my command line, i.e.,

>emacs &

sometimes the bug actually sits in front of the computer, as we all know
;-)

Apparently you are not aware of the 'session' concept of org source
blocks (please refer to the org manual). 
This is nothing specific to ob-picolisp, but holds for all ob languages
that do allow for sessions:

,
| * Picolisp scr-block test
| 
| #+BEGIN_SRC picolisp  :session pil1
|  (setq X1 (+ 3 4))
| #+END_SRC
| 
| #+results:
| : 7
| 
| 
| #+BEGIN_SRC picolisp  :session pil1
| (setq X2 (+ X1 1))
| #+END_SRC
| 
| #+results:
| : 8
| 
| 
| #+BEGIN_SRC picolisp  :session pil1
| (de foo1 (X) (+ X 2))
| #+END_SRC
| 
| #+results:
| : foo1
| 
| #+BEGIN_SRC picolisp  :session pil1 :results raw
| (setq X3 (foo1 8))
| #+END_SRC
| 
| #+results:
| 10
`

And, with a session, you do have a related interactive repl buffer in
Emacs called "pil1", thats reflects all evaluations of the code blocks
in the org file, and allows for user input just like the PicoLisp repl:

,
| (setq X1 (+ 3 4))
| 'org-babel-picolisp-eoe
| : -> 7
| : -> org-babel-picolisp-eoe
| : (setq X2 (+ X1 1))
| 'org-babel-picolisp-eoe
| -> 8
| : -> org-babel-picolisp-eoe
| : (de foo1 (X) (+ X 2))
| 'org-babel-picolisp-eoe
| -> foo1
| : -> org-babel-picolisp-eoe
| : (setq X3 (foo1 8))
| 'org-babel-picolisp-eoe
| -> 10
| : -> org-babel-picolisp-eoe
| : 
`

Hope that helps
