SYNOPSIS

$re = wc2re 'a{b?,c}*' => 'unix'; # Do it Unix style.
$re = wc2re 'a?,b*' => 'win32'; # Do it Windows style.

DESCRIPTION
In many situations, users may want to specify patterns to match but
don't need the full power of regexps. Wildcards make one of those sets
of simplified rules. This module converts wildcard expressions to Perl
regular expressions, so that you can use them for matching. It handles
- the "*" and "?" jokers, as well as Unix bracketed alternatives "{,}",
- and uses the backspace ("\") as an escape character. Wrappers are
- provided to mimic the behaviour of Windows and Unix shells.
+ the "*" and "?" shell jokers, as well as Unix bracketed alternatives
+ "{,}", but also "%" and "_" SQL wildcards. Backspace ("\") is used as an
+ escape character. Wrappers are provided to mimic the behaviour of
+ Windows and Unix shells.
VARIABLES
These variables control if the wildcards jokers and brackets must
capture their match. They can be globally set by writing in your program
$Regexp::Wildcards::CaptureSingle = 1;
- # From then, the '?' joker is capturing
+ # From then, "exactly one" wildcards are capturing
or can be locally specified via "local"
{
- local $Regexp::Wildcards::CaptureAny = 1;
- # In this block, the '?' joker is capturing.
+ local $Regexp::Wildcards::CaptureSingle = 1;
+ # In this block, "exactly one" wildcards are capturing.
...
}
# Back to the situation from before the block
functions.
$CaptureSingle
- When this variable is true, each occurence of the unescaped "?" joker is
- made capturing in the resulting regexp (they are be replaced by "(.)").
- Otherwise, they are just replaced by ".". Default is the latter.
+ When this variable is true, each occurence of unescaped *"exactly one"*
+ wildcards (i.e. "?" jokers or "_" for SQL wildcards) are made capturing
+ in the resulting regexp (they are be replaced by "(.)"). Otherwise, they
+ are just replaced by ".". Default is the latter.
+ For jokers :
'a???b\\??' is translated to 'a(.)(.)(.)b\\?(.)' if $CaptureSingle is true
'a...b\\?.' otherwise (default)
+ For SQL wildcards :
+ 'a___b\\__' is translated to 'a(.)(.)(.)b\\_(.)' if $CaptureSingle is true
+ 'a...b\\_.' otherwise (default)
+
$CaptureAny
- By default this variable is false, and successions of unescaped "*"
- jokers are replaced by one single ".*". When it evalutes to true, those

$CaptureBrackets
If this variable is set to true, valid brackets constructs are made into
"( | )" captures, and otherwise they are replaced by non-capturing
"wc2re_jokers"
This function takes as its only argument the wildcard string to process,
