How to strip inner whitespace in rails

Ruby
1

I want to strip any whitespace that more than 1 to be 1

For example “A B C” ===> “A B C”

        "Very    Important" ===> "Very Important"

split() rules the world. squeez()…not so much.

s.split().join(" ")

…but if you are a regex addict, then gsub() is your fix:

result = s.gsub(/\s+/) do |match|
" "
end

Why? String#squeeze performs precisely what the OP asks for. There’s
nothing as concise as that.

If what needs to be collapsed is whitespace in the \s sense, then I
would perhaps swtich to gsub:

str.gsub(/\s+/, ’ ')

They’re completely different methods, though. They’re not in a death
struggle :slight_smile: They do different things. I wouldn’t want to try this
with split:

“abc deffff ghi”.squeeze(" f") => “abc def ghi”

squeeze is a better fit, it terms of its stated purpose, than split,
if you want to condense multiple occurrences into one. It’s also
faster, in every benchmark I can come up with:

    user     system      total        real
2.630000   0.010000   2.640000 (  2.665775)
0.140000   0.000000   0.140000 (  0.136925)

(That’s for removing extra " "s from a string of length about 500.)

I agree, unless speed is an issue, in which case you might be better
off with:

str.squeeze(" \t\n\r\f")

although it’s a bit more heavy-handed and I’m probably forgetting one.

In Rails (and nobody mentioned it), use String#squish or String#squish!

Agreed, I would default to gsub here because I find \s more obvious
than the character set, but if speed is an issue I’d go with sqeeze as
well.

The question was about removing inner whitespace, though. The only
thing squish does that squeeze or gsub don’t do is remove outer
whitespace.
