Wild

The Wild object allows a script to access the in-built pattern matching functions in Opus. Even though most ActiveX scripting languages have their own pattern matching support (usually via a regular expression system of some sort), you may wish to use the one that Opus provides for consistency with internal Opus functions.

You can create a Wild object using the FSUtil.NewWild method. To use the Wild object, you must first give it the pattern to match against (this step is called "parsing the pattern"). You can do this when it is created or later on using the Parse method. Once the object has a pattern you can call the Match method to test a string against the pattern.

Property Name Return Type Description

<default value>

string

Returns the current pattern in the Wild object

Method Name Arguments Return Type Description

EscapeString

<string:input>
<string:type>

string

Escapes all wildcard characters in the input string and returns the result. For example, "the * 'dog' said *" would be conterted to "the '* ''dog'' said '*".

The optional type argument lets you specify the conversion:
none: Escape characters used in standard pattern matching
r: Escape characters used in regular expressions 
b: Double all back-slashes
n: Double all back-slashes that come before the letter 'n'
Note that these modes cannot be combined.

Match

<string:test>

bool

Compares the specified string against the previously-parsed pattern, and returns True if it matches.

Parse

<string:pattern>
<string:flags>

bool

Parses the supplied pattern. The flags string is optional - if supplied it must be a string consisting of one or more of the following characters:

c - case-sensitive (otherwise pattern matching is not case-sensitive) 
d - DOS only (only standard MS-DOS wildcards are supported)
f - filename mode (special handling for matching filenames)
r - regular expression (otherwise standard pattern matching is used)
