Ruby Versions:

ruby 1.6.7 (2002-03-01) [i686-cygwin] and

ruby 1.7.3 (2002-09-25) [i386-cygwin]

Platform: Windows 2000 SP3

I am using string.gsub to replace “/%[0-8a-fA-F][0-8a-fA-F]/” with “_”.

The following two gsub is to prove that gsub does sub ‘%29’

“Simple+SNMP+%28s2nmp%29”.gsub( /%2./ , “_” )
—> “Simple+SNMP+s2nmp”

“Simple+SNMP+%28s2nmp%29”.gsub( /%\d\d/ , “_” )
—> “Simple+SNMP+s2nmp”

The following gsub is what I would need to use in a program

“Simple+SNMP+%28s2nmp%29”.gsub( /%[0-8a-fA-F][0-8a-fA-F]/ , “_” )
—> “Simple+SNMP+_s2nmp%29”

Here is some other strings that did not gsub correctly

I am using string.gsub to replace “/%[0-8a-fA-F][0-8a-fA-F]/” with “_”.
…
The following gsub is what I would need to use in a program

“Simple+SNMP+%28s2nmp%29”.gsub( /%[0-8a-fA-F][0-8a-fA-F]/ , “_” )
—> “Simple+SNMP+_s2nmp%29”

Why would it replace %29? your matching 0-8, not 0-9.

I was thinking of Hex ranges, not base 10

The other option is to use cgi-lib to unescape the string and use a
regex to replace any character you don’t want to see:

require ‘cgi-lib’

CGI::unescape(str).gsub(/[^a-zA-Z0-9_+-]/n) { ‘_’ }
