O.o You have 3000 classes? I can't imagine such a project.

Anyway, there are ways you could do this, but they would require the
blackest of magics (hooking into require or using set_trace_func, and then
parsing the files in some manner to identify the namespaces around the
classes so you can locate them to include the module). Really, what Robert
suggested makes the most sense, include it into Object.

But honestly, with a project that big, I think I'd want everything to be
absolutely explicit all the time, anyway.

3000 is a huge number, though. Are you generating code? Why do all of your
classes need to include a colourization module? I very rarely need any such
thing, perhaps there is a deeper issue here which would be more useful to
discuss than this idea (which is a highly questionable one anyway).

Hi.<br>
<br>
I would like to know how I could save one line of code.<br>
<br>
Situation right now:<br>
<br>
=A0 require &#39;evil_module&#39;<br>
<br>
=A0 class Foo<br>
=A0 =A0 include EvilModule<br>
=A0 end<br>
<br>
Everyone knows this, this works fine.<br>
<br>
However, what I now want to do is, use only require,<br>
and have this module included into ALL classes of<br>
the .rb file. In other words:<br>
<br>
<br>
=A0 require &#39;evil_module&#39;<br>
<br>
=A0 class Foo<br>
=A0 end<br>
<br>
Should become the same as the above.<br>
<br>
But only in .rb files from where the require is used.<br>
<br>
Is this possible? I was told it may be possible via<br>
the required hook, but it would require changing<br>
modules globally (monkey patch), which I absolutely<br>
would not want to do.<br>
<br>
The reason why I need this, before anyone asks:<br>
<br>
I have a global colourizer method, which I use<br>
for ALL my ruby projects and all my ruby classes,<br>
but optionally. I.e. I want to toggle and control<br>
whether to use ansicolours or not.<br>
<br>
The current code I have requires me to use an<br>
explicit include, which is ok, but I&#39;d rather<br>
be able to eliminate one line of code, which<br>
would in turn eliminate around 3000 lines of<br>
code (the amount of classes I wrote in ruby so<br>
far).<br>
