Hi,
I have written a patch that adds regular expression literal support for
Vala. See more details in
https://bugzilla.gnome.org/show_bug.cgi?id=607702
The following example demonstrates the feature:
-----------
using GLib;
static int main (string[] args)
{
MatchInfo info;
// Simple greedy regular expression matching.
var str1 = "mississippi";
if (@/(is.*ip)/.match (str1, 0, out info)) {
stdout.printf ("Part of %s is '%s'...\n", str1, info.fetch (1));
} else {
stdout.printf ("Did not match at all.\n");
}
// Match caseless.
var str2 = "demonStration";
if (@/mon(str.*o)n/i.match (str2, 0, out info)) {
stdout.printf ("Part of %s is '%s'...\n", str2, info.fetch (1));
} else {
stdout.printf ("%s did not match at all.\n", str2);
}
// Match and pick substrings.
var ts = "Time: 10:42:12";
if (@/Time: (..):(..):(..)/.match (ts, 0, out info)) {
stdout.printf ("%s\n\thours = %s\n\tminutes = %s\n\tseconds = %s\n\n",
ts, info.fetch (1), info.fetch (2), info.fetch (3));
}
// Replace demo: word swapping
try {
var str = "apple grape";
stdout.printf ("'%s' becomes '%s'\n", str, @/^([^ ]*) *([^ ]*)/.replace
(str, -1, 0, """\2 \1"""));
} catch (RegexError err) {
// Replacing still needs exception catching
message (err.message);
}
return 0;
}
----
Any comments welcome.
Regards,
JP
