short cut for gsub("word",""

Aryk Grosz

is there any shortcut for removing a string of characters from text,
like gsub("word",""). I looked into String#delete but it will delete all
the characters in the entire word.

Im guessing something like this already exists.

I'm kind of surprised String#- doesn't work (it isn't defined)

str["word"] = ""
str[/word/] = ""

but these only do the first instance.

If you find yourself writing

str.gsub! /word/, ''

repeatedly, to the point where it is tiresome, then factor it out
yourself, depending on exactly what your needs are. e.g.

class String
def remove!(str)
gsub!(str, '')
end
def remove(str)
res = dup
res.remove!(str)
res
end
end
