regex - How can I remove the string "\n" from within a Ruby string? -

-

i have string:

"some text\nandsomemore"

i need remove "\n" it. i've tried

"some text\nandsomemore".gsub('\n','')

but doesn't work. how do it? reading.

you need use "\n" not '\n' in gsub. different quote marks behave differently.

double quotes " allow character expansion , expression interpolation ie. let use escaped control chars \n represent true value, in case, newline, , allow use of #{expression} can weave variables and, well, pretty ruby expression text.

while on other hand, single quotes ' treat string literally, there's no expansion, replacement, interpolation or have you.

in particular case, it's better use either .delete or .tr string method delete newlines.
