RegEx Transformation Service

Given a source string and a regular expression, use the regular expression to yield a transformed string.

If the regular expression is in the format s/<regex>/result/g, replace all occurrences of <regex> in the source string with result and return the result.

If the regular expression is in the format s/<regex>/result/, replace the first occurrence of <regex> in the source string with result and return the result.

If the regular expression contains a capture group, return the captured string. The regular expression in this case is further restricted to isolate a complete line by adding ^ to the beginning and $ to the end.

Examples

With the input string My network does not work.:

regular expression	output
s/work/cast/g	"My netcast does not cast."
.*(\snot).*	" not"
