Susy: question about +omega mixin
Charles Roper
In the readme for Susy, it states, in relation to the +omega and other
mixins:
"In nested contexts, all of these mixins take an extra final argument,
the width in columns of the parent (nesting) element."
In studying the Sass for Susy (_grid.sass), this statement had me
totally scratching my head. I couldn't see why or how the width in
columns came into it; seemingly you're just flipping a boolean to true,
rather than actually setting a value. This had me confused for quite
some time (I know, I'm a bit slow) as I thought there *must* be
something I misunderstood about Susy, Sass or Compass for the code to
say one thing, while the docs suggested another.
But anyway, can I just confirm that we can set that value to *anything*
and it will have the same effect? That is, the presence of any value
other than nil returns True? Actually, even nil seems to get implicitly
converted to a string and therefore returns True.
Or have I indeed misunderstood something, somewhere?
Cheers,
Charles
p.s Really enjoying messing about with Susy so far.

Glad you are enjoying Susy so far. You are absolutely right. All the
code cares about with +omega is if you are in a nested context or not.
I wrote the tutorial (and all my own production code) with the
specific context for simplicity. It keeps a consistent syntax with the
other mixins (+culumns, +pad, etc.) that do need to know the exact
context, and '3' is easier to write anyway than '"True"'.
Now that you've discovered my secret, you can do as you like. I still
plan to recommend supplying context. I think it's a good habit to be
in for using Susy as a whole.
Cheers,
Eric

Good to know, thanks for the explanation. I agree entering the context
makes sense and it is indeed much easier than typing "True". Perhaps
all that's required to avoid confusing newbies like me is a little
explanation on this somewhere, perhaps in the source?
Cheers,
