strange behaviour to me

strange behaviour to me

[Mr. Peter Ivanyi]

Hi,

I have a strange situation (at least to me). "match:string"
becomes unbound in a script. For example if I start guile from a shell prompt:

peteri@mercury $ guile
guile> %load-path
("/home/peteri/temp/guile/install-1.5.4/share/guile/site"
"/home/peteri/temp/guile/install-1.5.4/share/guile/1.5.4"
"/home/peteri/temp/guile/install-1.5.4/share/guile" ".")
guile> match:string
#<procedure match:string (match)>
guile> 

but from a script "match:string" is not bounded:

peteri@mercury $ cat cc.scm
(display %load-path)(newline)
match:string
peteri@mercury $ guile -s cc.scm
(/home/peteri/temp/guile/install-1.5.4/share/guile/site
/home/peteri/temp/guile/install-1.5.4/share/guile/1.5.4
/home/peteri/temp/guile/install-1.5.4/share/guile .)
ERROR: Unbound variable: match:string
peteri@mercury $ 


I do not understand it. How can I have "match:string" in my script ???

Thanx for your help in advance.

				Peter Ivanyi

The cause: if run interactively guiles default module is 'guile-user', if 
run from a script it is 'guile' (humpf!). Try the following:

|  bash-2.05$ guile
|  guile> match:string
|  #<procedure match:string (match)>
|  guile> (define-module (guile))             ; what is active when run as a script
|  #<module (guile) 8081620>
|  guile> match:string
|  ERROR: Unbound variable: match:string
|  ABORT: (unbound-variable)
|  guile> (define-module (guile-user))        ; back to interactive guile-user
|  #<directory (guile-user) 80835c0>
|  guile> match:string
|  #<procedure match:string (match)>
|  guile> 
|  

You need to import match:string from (ice-9 regex) if you want to use it from
within a script.

Hmm, thinking of it -- why is (ice-9 regex) loaded in (guile-user) ?

Try :

    (use-modules (ice-9 regex))
