But 2 \\ works okay. What I get in Linux from your second query is ?- write('e\tf'). e f yes because '\t' is passed to Ciao Prolog verbatim and interpreted as a tabular by Ciao Prolog; see also: ?- set_prolog_flag(write_strings, off). yes ?- atom_codes('e\tf', X). X = [101,9,102] ? yes where \t translates to the ninth ascii code (sorry about this low level parlance). However I guess that this is not what is happening in your case, i.e., Ciao Prolog is not receiving a backslash _and_ a 't', but some precooked code. Again, if this is so, it is the Emacs mode which should be change to behave properly under XEmacs. MCL __________________________________________ ¡Ay, qué miedo saber tanto!

I guess I wasn't clear. My problem is not with ensure_loaded, as I can type what you wrote, but with the emacs system which generates the wrong form of the path name, as far as Ciao is concerned. ----- Original Message ----- From: "Guy Murphy" <guy.murphy(a)easynet.co.uk> To: "Alan Baljeu" <alanb(a)cornerstonemold.com> Sent: Friday, June 21, 2002 9:18 AM Subject: Re: Emacs ciao-Prolog buffer in Windows > Have you tried... > > ensure_loaded('C:/ciao-1.8p2Win32/tmp/test.pl'). > > ...for the most part Windows doesn't care if you use forward or backslashes, > and forward slashes don't have to be escaped, and are compatible with more > systems. > > If that's not the issue, then it may well be that the path the file is > visible under Cygwin is different that under the native OS. > > Cheers, > Guy. > > ----- Original Message ----- > From: "Alan Baljeu" <alanb(a)cornerstonemold.com> > To: <ciao-users(a)clip.dia.fi.upm.es> > Sent: Friday, June 21, 2002 11:54 AM > Subject: Emacs ciao-Prolog buffer in Windows > > > > > > The system seems mostly to work, except for loading info from buffers into > > the shell.

Re: Native Compile Question

It is not that it has been "ruled out"; rather, it is "not yet implemented". Historically, we started with an implementation based on a bytecode interpreter, and we have been using it so far. But a compiler based on translation to C is on the works, although it is not finished yet (it is not even in alpha state). As Daniel Diaz, the main GNU Prolog's implementor, can say, a native compiler is a non-trivial task, and maintaining different back-ends for different architectures (say, i386, SPARC, MIPS, Power PC...) easily becomes a lot of work. That is one of the reasons why we chose to translate to C. MCL ___________________________________________ ¡Hay, qué miedo saber tanto!

Emacs ciao-Prolog buffer in Windows
by Alan Baljeu 21 Jun '02

The system seems mostly to work, except for loading info from buffers into the shell. The problem is those \\, put in by the ^c-l command. Any hints on how to make this work with forward slashes to make Ciao happy? ?- ensure_loaded('C:\ciao-1.8p2Win32\tmp\test.pl'). {ERROR: absolute_file_name/7, arg 1 - file C:iao-1.8p2Win32 mp est.pl not found} I'm using Xemacs 21.4.

Read a string and put it in a list
by José Antonio Echagüe Burgos 10 Jun '02

10 Jun '02

Hello all. How I can, in CIAO Prolog, read a string of characters and put it in a list? For example: my name is jose and obtain [my,name,is,jose] I need make this for "speak" to the program in natural language, and after build a database consult, for example: give me the books that treat of libraries and archives and users Now, in my program, I must ask with the following format: [give,me,the,books,that,treat,of,libraries,and,archives,and,users] After, with a pattern, I get the tail of the list, [libraries,and,archives,and,users], and delete the non-significative words ("and" in this case). Therefore, my problem is convert the string of characters in a list of elements. Thank you for your help, a greeting.
