regexp_code (library)

Usage:match_shell(Exp,IN,Rest)

Matches IN against Exp. Rest is the longest remainder of the string after the match. For example, match_shell("??*","foo.pl",Tail) succeeds, instantiating Tail to "o.pl".

• The following properties should hold at call time:
  (regexp_code:shell_regexp/1)Exp is a shell regular expression to match against.
  (regexp_code:string/1)IN is a string.
  (regexp_code:string/1)Rest is a string.

Usage:match_shell(Exp,IN)

Matches completely IN (no tail can remain unmatched) against Exp similarly to match_shell/3.

• The following properties should hold at call time:
  (regexp_code:shell_regexp/1)Exp is a shell regular expression to match against.
  (regexp_code:string/1)IN is a string.

Usage:match_posix(Exp,IN)

Matches completely IN (no tail can remain unmatched) against Exp similarly to match_posix/3.

• The following properties should hold at call time:
  (regexp_code:shell_regexp/1)Exp is a shell regular expression to match against.
  (regexp_code:string/1)IN is a string.

Usage:match_posix(Exp,In,Match,Rest)

• The following properties should hold at call time:
  (regexp_code:shell_regexp/1)Exp is a shell regular expression to match against.
  (regexp_code:string/1)In is a string.
  (basic_props:list/2)Match is a list of strings.
  (regexp_code:string/1)Rest is a string.

Usage:match_posix_rest(Exp,IN,Rest)

Matches IN against Exp. Tail is the remainder of the string after the match. For example, match_posix("ab*c","abbbbcdf",Tail) succeeds, instantiating Tail to "df".

• The following properties should hold at call time:
  (regexp_code:posix_regexp/1)Exp is a posix regular expression to match against.
  (regexp_code:string/1)IN is a string.
  (regexp_code:string/1)Rest is a string.

Usage:match_posix_matches(Exp,IN,Matches)

Matches completely IN against Exp. Exp can contain anchored expressions of the form \(regexp\). Matches will contain a list of the anchored expression which were matched on success. Note that since POSIX expressions are being read inside a string, backslashes will have to be doubled. For example,

?- match_posix_matches("\\(aa|bb\\)\\(bb|aa\\)", "bbaa", M).
M = ["bb","aa"] ? ;
no

?- match_posix_matches("\\(aa|bb\\)\\(bb|aa\\)", "aabb", M).
M = ["aa","bb"] ? ;
no

• The following properties should hold at call time:
  (regexp_code:shell_regexp/1)Exp is a shell regular expression to match against.
  (regexp_code:string/1)IN is a string.
  (basic_props:list/2)Matches is a list of strings.

Usage:match_struct(Exp,IN,Rest,Tail)

Matches IN against Exp. Tail is the remainder of the list of atoms IN after the match. For example, match_struct([a,*(b),c],[a,b,b,b,c,d,e],Tail) succeeds, instantiating Tail to [d,e].

• Call and exit should be compatible with:
  (regexp_code:struct_regexp/1)Exp is a struct regular expression to match against.
  (regexp_code:string/1)IN is a string.
  (regexp_code:string/1)Rest is a string.

Usage:match_pred(Pred1,Pred2)

Tests if two predicates Pred1 and Pred2 match using posix regular expressions.

Usage:replace_first(IN,Old,New,Resul)

Replace the first ocurrence of the Old by New in IN and copy the result in Resul.

• The following properties should hold at call time:
  (regexp_code:string/1)IN is a string.
  (regexp_code:posix_regexp/1)Old is a posix regular expression to match against.
  (regexp_code:string/1)New is a string.
  (regexp_code:string/1)Resul is a string.

Usage:replace_all(IN,Old,New,Resul)

Replace all ocurrences of the Old by New in IN and copy the result in Resul.

• The following properties should hold at call time:
  (regexp_code:string/1)IN is a string.
  (regexp_code:posix_regexp/1)Old is a posix regular expression to match against.
  (regexp_code:string/1)New is a string.
  (regexp_code:string/1)Resul is a string.

Usage:shell_regexp(P)

P is a shell regular expression to match against.

Usage:posix_regexp(P)

P is a posix regular expression to match against.

Usage:struct_regexp(P)

P is a struct regular expression to match against.

(Trust) Usage:define_flag(Flag,FlagValues,Default)

• The following properties hold upon exit:
  (basic_props:atm/1)Flag is an atom.
  (basic_props:flag_values/1)Define the valid flag values
