Pattern

The g_pattern_match* functions match a string against a pattern containing '*' and '?' wildcards with similar semantics as the standard glob() function: '*' matches an arbitrary, possibly empty, string, '?' matches an arbitrary character.

Note that in contrast to glob(), the '/' character can be matched by the wildcards, there are no '...' character ranges and '*' and '?' can not be escaped to include them literally in a pattern.

When multiple strings must be matched against the same pattern, it is better to compile the pattern to a GPatternSpec using g_pattern_spec_new() and use g_pattern_match_string() instead of g_pattern_match_simple(). This avoids the overhead of repeated pattern compilation.

class Pattern {

protected

GPatternSpec* gPatternSpec;

GPatternSpec* getPatternStruct();

void* getStruct();

this(GPatternSpec* gPatternSpec);

~this();

this(string pattern);

void free();

int equal(Pattern pspec2);

int match(uint stringLength, string string, string stringReversed);

int matchString(string string);

static int matchSimple(string pattern, string string);

}

Constructors

this this(GPatternSpec* gPatternSpec): Sets our main struct and passes it to the parent class
this this(string pattern): Compiles a pattern to a GPatternSpec.

Destructor

~this ~this(): Undocumented in source.

Functions

equal int equal(Pattern pspec2): Compares two compiled pattern specs and returns whether they will match the same set of strings.
free void free(): Frees the memory allocated for the GPatternSpec.
getPatternStruct GPatternSpec* getPatternStruct(): Undocumented in source. Be warned that the author may not have intended to support it.
getStruct void* getStruct(): the main Gtk struct as a void*
match int match(uint stringLength, string string, string stringReversed): Matches a string against a compiled pattern. Passing the correct length of the string given is mandatory. The reversed string can be omitted by passing NULL, this is more efficient if the reversed version of the string to be matched is not at hand, as g_pattern_match() will only construct it if the compiled pattern requires reverse matches. Note that, if the user code will (possibly) match a string against a multitude of patterns containing wildcards, chances are high that some patterns will require a reversed string. In this case, it's more efficient to provide the reversed string to avoid multiple constructions thereof in the various calls to g_pattern_match(). Note also that the reverse of a UTF-8 encoded string can in general not be obtained by g_strreverse(). This works only if the string doesn't contain any multibyte characters. GLib offers the g_utf8_strreverse() function to reverse UTF-8 encoded strings.
matchString int matchString(string string): Matches a string against a compiled pattern. If the string is to be matched against more than one pattern, consider using g_pattern_match() instead while supplying the reversed string.

Static functions

matchSimple int matchSimple(string pattern, string string): Matches a string against a pattern given as a string. If this function is to be called in a loop, it's more efficient to compile the pattern once with g_pattern_spec_new() and call g_pattern_match_string() repeatedly.
