Regex match a period

[sjackman]

I'd expect \\. to match a period. Neither \. nor \\. work. [.] does work.

❯❯❯ printf "hi\na.b\nbye\n" | mlr -p filter '$1 =~ "\."'
❯❯❯ printf "hi\na.b\nbye\n" | mlr -p filter '$1 =~ "\\."'
❯❯❯ printf "hi\na.b\nbye\n" | mlr -p filter '$1 =~ "[.]"'
a.b

:( Oddly I ran into this just today. Very weird it's not working. I'm just wrapping the C regex library; maybe I bungled something backslashwise.

Thanks for the quick fix, John.
