notepad++ - Regex pattern repetition and capturing -

i had translate propkeys.h (in c[++]?) in c#.

my goal come from:

define_propertykey(pkey_audio_channelcount, 0x64440490, 0x4c8b, 0x11d1, 0x8b, 0x70, 0x08, 0x00, 0x36, 0xb1, 0x1a, 0x03, 7); 

to:

public static propertykey audio_channelcount = new propertykey(new guid("{64440490-4c8b-11d1-8b70-080036b11a03}")); 

i using notepad++ regex, i'm open other scriptable solution (perl, sed...). please no compiled language (as c#, java...).

i ended (working):

// turns guid string // find (line breaks inserted convenience): 0x([[:xdigit:]]{8}),\s*0x([[:xdigit:]]{4}),\s*0x([[:xdigit:]] {4}),\s*0x([[:xdigit:]]{2}),\s*0x([[:xdigit:]]{2}),\s*0x([[:xdigit:]] {2}),\s*0x([[:xdigit:]]{2}),\s*0x([[:xdigit:]]{2}),\s*0x([[:xdigit:]] {2}),\s*0x([[:xdigit:]]{2}),\s*0x([[:xdigit:]]{2})  // replace with: new guid\("{$1-$2-$3-$4$5-$6$7$8$9$10$11}"\)  // final pass // find what: ^define_propertykey\(pkey_(\w+),\s*(new guid\("\{[[:xdigit:]|\-]+"\)),\s*\d+\);$ // replace with: public static propertykey $1 = new propertykey\($2\); 

while working, feel first pass odd. wanted replace tons of {2} repeating one. like:

(0x([[:xdigit:]]){2},\s*)+ 

but can't work groups. can tell me "standard" way of doing regexes ?

unfortunately when perform match using quantifier, group match whole text, more "classy" solution use equivalent perl's \g metacharacter, starts match after end of previous match. can use (perl):

my $text = "define_propertykey(pkey_audio_channelcount, 0x64440490, 0x4c8b, 0x11d1, 0x8b, 0x70, 0x08, 0x00, 0x36, 0xb1, 0x1a, 0x03, 7);"; $res = "public static propertykey audio_channelcount = new propertykey(new guid(\"{";  if($text =~ m/0x((?:\d|[a-f]){8}),\s*0x((?:\d|[a-f]){4}),\s*0x((?:\d|[a-f]){4})/gc) {    $res .= $1 . "-" . $2 . "-" . $3 . "-"; }  if($text =~ m/\g,\s*0x((?:\d|[a-f]){2}),\s*0x((?:\d|[a-f]){2})/gc)# {    $res .= $1 . $2 . "-"; }  while($text =~ m/\g,\s*0x((?:\d|[a-f]){2})/gc) {    $res .= $1; }  $res .= "}\"))";  print $res . "\n"; 

after should have result string on $res. output when running script was:

public static propertykey audio_channelcount = new propertykey(new guid("{64440490-4c8b-11d1-8b70-080036b11a03}"))
