Guys,
When we use
require ‘some_code’.
where (i.e., in which directories) does require looks for ‘some_code’?
Thanks,
Maurício
require 'some_code'.
where (i.e., in which directories) does require looks for 'some_code'?
$LOAD_PATH
pigeon% ruby -e 'p $LOAD_PATH'
["/usr/local/lib/ruby/site_ruby/1.6",
"/usr/local/lib/ruby/site_ruby/1.6/i686-linux",
"/usr/local/lib/ruby/site_ruby", "/usr/local/lib/ruby/1.6",
"/usr/local/lib/ruby/1.6/i686-linux", "."]

Short answer: those listed in the global variable $:
Longer answer:
candle:~$ ri require
-------------------------------------------------------- Kernel::require
require( aString ) → true or false
Ruby tries to load the library named aString, returning true if
successful. If the filename does not resolve to an absolute path,
it will be searched for in the directories listed in $:. If the
file has the extension ``.rb'', it is loaded as a source file; if
the extension is ``.so'', ``.o'', or ``.dll'',[Or whatever the
default shared library extension is on the current platform.] Ruby
loads the shared library as a Ruby extension. Otherwise, Ruby tries
adding ``.rb'', ``.so'', and so on to the name. The name of the
loaded feature is added to the array in $". A feature will not be
loaded if it already appears in $". require returns true if the
feature was successfully loaded.
require "my-library.rb"
require "db-driver"

Interesting… The good-style way of changing it is just
$LOAD_PATH.push ‘directory’ ?

Depending on the situation, you might want to shift instead of
pushing, so that the directories you’re adding get searched first.
