Aliasing, and another regex question

J. Cooper

2/27/2008 6:31:00 PM

Is there a preferred way to alias inconveniently long things like
Oniguruma::ORegexp?

Is it possible to have one regex that matches all lines that have word
"foo", but only if word "bar" doesn't appear anywhere on the line?

Sorry for yet more questions!

OReg = Oniguruma::ORegexp

Well you can do something like OR = Oniguruma::ORegexp

The best way would probably be to just use two regexen. One to select all
lines with foo and another to filter out those with bar.

Sounds good on the alias :)

I figured... I was really hoping I could do it in one line, as this was
a regex I was using in a text editor (TextMate) to find all lines in a
group of files that contained one word but not another.

Well, you can do it in one line just not with a single regex (or maybe
you can do that too, but that'd probably more complicated and possibly
longer):
lines.select {|l| l =~ /foo/ && l !~ /bar/}
