RE: String Library
Bonjour
Je vous propose une nouvelle fonction à ajouter à la library:

Hello
I propose a new function to add to the library :

Code:
EXPORT EXTRACT(s,o)
//string,char or {char,num}
BEGIN
 LOCAL n:=-1,p,c;
 IF TYPE(o)==6 THEN
  c:=o(1);n:=o(2);
 ELSE
  c:=o;
 END;
 c:=typara(c);p:=INSTRING(s,c);
 n:=IFTE(n<0,DIM(s)-p+1,n);
 IF p==0 OR n==0 THEN
  "";
 ELSE
  MID(s,p,n);
 END;
END;
exemple:
example:
EXTRACT("250_km","_") -> "_km"
EXTRACT("250_km de bouchons",{"_",3}) -> "_km"

RE: String Library
Bonjour
Les fonctions LFORMAT ET RFORMAT ne fonctionnent pas correctement.
Exemple :
LFORMAT(16,2,"0") renvoie "0016" au lieu de "16".
Ceci est du à un bug de la fonction MAKELIST.
Voici une version corrigée de setstr qui est utilisée par ces deux fonctions:

Hello
The LFORMAT AND RFORMAT functions do not work properly.
Example :
LFORMAT (16,2,"0" ) returns " 0016 " instead of "16" .
This is due to a bug in the MAKELIST function.
Here is a corrected version of setstr that is used by these two functions:

Code:

setstr(c,n)
BEGIN
 LOCAL i,r;
 c:=typara(c);r:="";
 FOR i FROM 1 TO n
  r:=r+c;
 END;
 r;
END;
Sorry

RE: String Library
Another function: replace a placeholder in a string with another
e.g. SREPL("Hello %w", "%w", "world") -> "Hello world"

Code:
EXPORT SREPL(str, key, val)
BEGIN
  LOCAL p;
  p := INSTRING(str, key);
  CASE
    IF p == 0 THEN  // Not found
      RETURN str;
    END;
    IF str == key THEN  // Placeholder is whole string
      RETURN val;
    END;
    IF p == 1 THEN  // Placeholder at start
      RETURN val + MID(str, DIM(key)+1);
    END;
    IF p == (DIM(str)-DIM(key)+1) THEN  // Placeholder at end
      RETURN LEFT(str, p-1) + val;
    END;
    DEFAULT RETURN LEFT(str, p-1) + val + MID(str, p+DIM(key));
  END;
END;

Sauf erreur, la fonction intégrée REPLACE permet cela.
Merci de vôtre intêret.

Hello

Unless you make a mistake, the built-in REPLACE function allows this.
Thanks for your interest.

From the User Guide:

REPLACE("123456", 2, "GRM") -> "1GRM56"

but

SREPL("123456", "2", "GRM") -> "1GRM3456"
