The regexp module actually uses the standard unix libregex library.

man 3 regex
man 7 re_format

^ and $ will matching beginning and end of lines.

[11]> (regexp:match "^bar"  "foo bar
bar bar
baz bar" :newline t)
#S(REGEXP:MATCH :START 8 :END 11)
[12]> 


[23]> (regexp:match "bar$"  "foo bar
bar bar
baz bar" :newline t)
#S(REGEXP:MATCH :START 4 :END 7)
[24]> 

Otherwise if you want to match the newline itself, just use it in the regexp:


[33]> (regexp:match "
"  "foo bar
bar bar
baz bar")
#S(REGEXP:MATCH :START 7 :END 8)
[34]>
