Question

I have an URI object.

require 'uri'
uri = URI.parse 'http://example.com'

I need to merge some path to this URI.

path = URI.escape('/?foo[123]=5')
uri.merge!(path)

And getting exception:

URI::InvalidURIError: bad URI(is not URI?): /?foo[123]=5

This is because some symbols in path considered as unsafe (“[” and “]”),
but those symbols ware not escaped by URI.escape.

I’m solving this issue using two URI.escape calls:

path = URI.escape(URI.escape('/?foo[123]=5'), '[]')
uri.merge!(path)

The question is: why URI.escape does not performs that escaping by default?

Or maybe there is some better way to do that?
