[gentoo-dev] USE flag name collision in use.local.desc "graphite"

[Walter Dnes]

  Is it considered a reportable bug?

[i660][waltdnes][~] grep :graphite /usr/portage/profiles/*.desc
/usr/portage/profiles/use.local.desc:dev-lang/gnat-gpl:graphite - Add support 
for the framework for loop optimizations based on a polyhedral intermediate 
representation
/usr/portage/profiles/use.local.desc:media-libs/harfbuzz:graphite - Use 
graphite to render complex non-Roman writing systems
/usr/portage/profiles/use.local.desc:sys-devel/gcc:graphite - Add support for 
the framework for loop optimizations based on a polyhedral intermediate 
representation

  The "graphite" USE flag means something entirely different for
harfbuzz, i.e. build media-libs/harfbuzz against media-gfx/graphite2

 So they are awkward to type inside a string that is all-caps?

Fair enough. FTR, I have no preference either way, this is 100%
bikeshedding if you ask me.

Also, I didn't mean to be rude, just wanted to point out that what you
said about being easier to type might not apply to everybody (in fact,
the opposite is probably true for most people). Another point against
hyphens is that all ebuild variables use underscore. But as I said I'm
fine either way.

I have a counter suggestion:

1. Leave @ECLASS-VARIABLE as-is
2. Leave @DEFAULT_UNSET as is
3. Document that underscores are to be used for all new tags
4. Add support for @ECLASS_VARIABLE that works the same as
   @ECLASS-VARIABLE
5. Don't go out of our way to migrate to @ECLASS_VARIABLE, just let it
   occur over time, particularly in conjunction with other major
   changes.

Mostly because @FOO_VARIABLE is suspiciously similar syntax to me as
other ALL CAPS variables used as ENV tokens in Bash.

And I can't think of a single instance where I've seen a language with
a convention that used ALL CAPS terms in conjunctions with hyphens,
( and regex with _ are ultimately simpler to reason about than ones
with - )

Because I cared enough to do the work. If you want it the other way around, 
then send the reverse patch instead of giving asshole comments.

So please remind me why everyone else has to adapt to your habits?
