ediprolog lets you interact with Prolog in all
Emacs buffers. You can consult Prolog programs and evaluate
The latest version of ediprolog is 1.2.
A prototype version for Scryer Prolog: ediprolog.el
For more information about Prolog development with Emacs, see PceProlog.
M-x package-install RET ediprolog RETAlternatively, copy ediprolog.el to your load-path and add the following form to your .emacs, then evaluate the form or restart Emacs:
(require 'ediprolog)After you have installed ediprolog, you can customize it with:
M-x customize-group RET ediprolog RET
(global-set-key [f10] 'ediprolog-dwim)If F10 is not free on your platform, bind ediprolog-dwim to any other key sequence. For example, to bind it to C-c C-e, use:
(global-set-key "\C-c\C-e" 'ediprolog-dwim)In the following, replace F10 with your custom binding.
%?- member(X, [a,b,c]).If you press F10 when point is on that query, you get:
%?- member(X, [a,b,c]). %@ X = a ; %@ X = b ; %@ X = c ; %@ false.
If you press F10 when point is not on a query, the buffer content is consulted in the Prolog process, and point is moved to the first error (if any). You do not need to save the file beforehand, since the buffer content (not the file) is consulted.
In transient mark mode, if the region is active, only the text in the region is consulted.
When waiting for output of the Prolog process, you can press C-g to unblock Emacs and continue with other work. To resume interaction with the Prolog process, use M-x ediprolog-toplevel RET.
For convenience, the most recent interactions with the Prolog process are logged in the buffer *ediprolog-history*.
Use M-x ediprolog-localize RET to make any Prolog process started in the current buffer buffer-local. This way, you can run distinct processes simultaneously. Revert with M-x ediprolog-unlocalize RET.
|C-0 F10||kill Prolog process|
|C-1 F10||always consult buffer (even if point is on a query)|
|C-2 F10||always consult buffer, using a new process|
|C-7 F10||equivalent to ediprolog-toplevel|
|C-u F10||first load buffer into existing process and then, if on a query, evaluate it|
|C-u C-u F10||like C-u F10, with a new process|
/* ?- Vs = [X,Y,Z], Vs ins 1..2, all_distinct(Vs). %@ false. */Using PceProlog, you can quickly create such comment blocks with C-c q.
