require "../foo"

Boris Glawe

Hi,

I have my code splitted up in several directories:

....
lib/foo.rb
lib/bar.rb
setttings/globalsettngs.rb
setttings/othersettings.rb
....

If for example foo.rb want to use classes, modules or methods from
"settings/globalesettings.rb" the ruby compiler refuses this in foo.rb:

require "../settings/globalsettings"

I always use this as a workaround:
$: << ".."
require "settings/globalsettings"

where $: is the variable storing the path where to search for files.

Is there a more elegant way to access files in "../settings"


thanks and greets

Boris

I assume, files in settings contain info that is specific to your code in
foo and bar which the user has to create / provide. In that case I'd also
rely on the user to set the require path so that his settings can be found.
I'd also probably not necessarily use "require" to load those settings.
This for example has the disadvantage that you cannot easily reload
settings. I'd probably rather read something like "~/.foo.rb" i.e. settings
stored in a default location (which might be overridden with a command line
switch).

Kind regards

These settings are not meant to be used by the user, but by the progammer. I've
stored Constants like names of cgi objects or strings that are used by the cgi
libraries to specify the html version of the generated html code in these modules.

Anyway it doesn't matter what my classes in /lib want to acces. I am looking for
a more elegant way to access classes in /settings from classes the are stored in
/lib. 'require ../settings/globalsettings" ' ist not accepted by the compiler as
I've alread said.

The programmer in this case is the user of your lib.

But you did actually include the opening quote, did you?

13:23:36 [timezones]: ruby -c -e 'require "../foo"'
Syntax OK
13:30:53 [timezones]: ruby -c -e 'require ../foo"'
-e:1: unterminated string meets end of file
-e:1: syntax error

My compiler accepts this (i.e. syntax ok). In which of the files do you
have this line? Is it in the main script or in the lib script? In your
scripts you can use somehing like

load "../settings/globalsettings.rb"
load File.join(File.dirname(__FILE__), "..", "settings",
"globalsettings.rb")

Kind regards
