Hi,
I need to replace ' by \'. How can I do that?

Thanks

This was harder than I thought...in "vi"(vim actually) I just had to:

1,$ s/'/\\'/g

But Ruby didn't seem to like that....

Anyway, for reasons unknown to me, this works:

puts "'hello'".gsub("'","\\\\'")

Cheers

John

how i wish the behaviour would change.
search the archives. this is a faq :slight_smile:

# puts "'hello'".gsub("'","\\\\'")

if like me, you want to lessen the those fences :slight_smile:
try,

"'hello'".gsub("'") { "\\'" }
#=> "\\'hello\\'"

or

"'hello'".gsub "'", %q[\\\']
#=> "\\'hello\\'"

for obvious reason, my brain prefers the former

kind regards -botp

oops sorry (I did it again)...perhaps you could include the link to
where this is explained though... :slight_smile:
