region(?A, -X) is det

Unify Unify X with the content of the buffer region when A == [], otherwise, with A.

 overwrite(+X:codes, ?_) is det

Kill the region, and insert X to the buffer.

 insert_buffer(+X:term) is det

Insert X into the current buffer.

 dired_mark_swipl is det

Mark Prolog files in the pacpl7 directory in dired mode.

 neighbor_string(+X:string, +B:string, +E:string, +I:integer, -S:string) is det

True if S is the minimum substring of X such that sub_string(X, J, K, _, S), J + length(B) =< I =< K - length(E), and that S has B as a prefix, and E as a suffix.

 wait(P:list_command, P) is det

Send a lisp Command P, and wait a response.

 line_get(-X:obj) is det

Unify X with [point(P), begin(B), end(E), line(R)], where P is the current point, B the beginning point, E the end point R the content of the line.

 prolog_symbol_at_point(-X:string) is det

True if X is unified with a symbol at the current line.

 find_handle_call(H:list, C:codes, ?X, ?Y) is det

Find an handle such that H matches the argument of the head of the handle, and let P be the body phrase of the handle. In case no handle being found, let P be the phrase term whose codes is C. Then, in any case, apply the phrase P to [X, Y].

 lisp_to_list(+X:term, -Y:list) is det

Ask emacs to eval an meta-exression X, and unify Y with a list returned from emacs.y

 read_term_from_lisp(-X:term) is det

Read a term converted from emacs-lisp text with nullstop.

 call_lisp(+X:term, Option) is det

Ask lisp to eval X as an S expression, with options term(V) : V is unified with a return term codes string(V) : ask emacs-lisp to use 'prin1_to_string' wait : ask emacs-lisp to send 'done' when done. lisp : ask emacs-lisp not to reply.

 call_lisp(+X:term) is det

Shorthand for call_lisp(X, wait).

 lisp(X) is det

Shorthand for call_lisp(X, noreply).

 wait(X) is det

Shorthand for call_lisp_wait(X).

 call_lisp_wait(X) is det

Shorthand for call_lisp(X, wait).

 call_lisp_value(X, Y) is det

Shorthand for call_lisp(X, term(Y)).

 call_lisp_string(X, Y) is det

Shorthand for call_lisp(X, string(Y)]).

 read_mini_buffer(+P:sring, -S:string) is det

Read a string from the emacs mini-buffer.

 set_string(+X:atom, +Y:text) is det

Ask emacs lisp to eval S-expression "(setq X Y)".

 get_string(X:atom, -V:string) is det

Unify V with the string that is bound to a lisp atom X.

 set_mark_region(X, X) is det

Mark paragraph region.

 global_set_kbd(A:string) is det

Set a global default short cut for a rolog script A.

 global_unset_kbd(K:string) is det

global-unset key in kbd form.

 meta_handle(+G, +M, +Sp, +P)

• +G : goal,
• +M : module prefix
• +Sp : a predicate with arity 4.
• +P : a list, [] or [_,_]

Execute G almost in the same way as for phrase(G, X, Y) when P = [X,Y], or call(G) when P=[]. For each atomic pharse P of G

meta_handle(B, M, Sp, [])

is executed when call(Sp, M, P, B) is true.

This predicate is convenient to test

handles, which may have handle calls in the body, and see their outputs on emacs buffer window.
