awk - MAWK: Store match() in variable -


i try use mawk match() built-in function doesn't have third value variable:

match($1, /9f7fde/) {   substr($1, rstart, rlength); }

see doc.

how can store output variable named var when later want construct output this?

edit2 - complete example:

input file structure:

<iframe src="https://vimeo.com/191081157" frameborder="0" height="481" width="608" scrolling="no"></iframe>|random title|uploader|fun|tag1,tag2,tag3 <iframe src="https://vimeo.com/212192268" frameborder="0" height="481" width="608" scrolling="no"></iframe>|random title|uploader|fun|tag1,tag2,tag3

parser.awk:

{   embed = $1;   title = $2;   user = $3;   categories = $4;   tags = $5; }  begin {   fs="|"; }  # regexp without pattern matching testing purposes match(embed, /191081157/) {   id = substr(embed, rstart, rlength); }  {   print id"\t"title"\t"user"\t"categories"\t"tags; }

expected output:

191081157|random title|uploader|fun|tag1,tag2,tag3

i want call id variable outside match() function.

mawk version:

mawk 1.3.4 20160930 copyright 2008-2015,2016, thomas e. dickey copyright 1991-1996,2014, michael d. brennan  random-funcs:       srandom/random regex-funcs:        internal compiled limits: sprintf buffer      8192 maximum-integer     2147483647

the obvious answer seem be

match($1, /9f7fde/) { var = "9f7fde"; }

but more general be:

match($1, /9f7fde/) { var = substr($1, rstart, rlength); }
