Using regex with newline "\n"

Question

Is it possible to use regex in spite of the newline character \n

e.g. this code works well

> "|text|".gsub(/\|(.+?)\|/){"###"}
=> "###"

this doesn't

> "|\n text|".gsub(/\|(.+?)\|/){"###"}
=> "|\n text|"

Answer 1

Here is an alternative to the m modifier (specific to your case):

"|\n text|".gsub(/\|([^\|]+?)\|/){"###"}

It will match until the next |.

Answer 2

Use the m modifier for multiline matches:

"|\n text|".gsub(/\|(.+?)\|/m){"###"}
