[gentoo-dev] [PATCH] use.desc: Introduce global USE=magic

[gentoo-dev] [PATCH] use.desc: Introduce global USE=magic

[Michał Górny]

USE=magic is currently used consistently by 12 packages:

app-arch/engrampa[magic] Enable filetype auto-detection via
  sys-apps/file
app-editors/nano[magic] Add magic file support (sys-apps/file) to
  automatically detect appropriate syntax highlighting
app-misc/vifm[magic] Use libmagic to determine mimetypes
app-misc/worker[magic] Add magic file support from sys-apps/file to
  automatically detect file types
app-text/zathura[magic] Use libmagic to determine mimetypes
media-gfx/qiv[magic] Use libmagic to determine mimetypes
media-libs/libextractor[magic] Enable magic support using sys-apps/file
media-sound/moc[magic] Use libmagic to determine mimetypes
net-misc/gerbera[magic] Use libmagic to determine file types
net-p2p/mldonkey[magic] enable use of libmagic
sci-geosciences/viking[magic] Use libmagic to determine mimetypes
www-servers/pshs[magic] Enable automatic detection of Content-Type using
  libmagic (sys-apps/file)

The USE flag naming feels a bit to be desired by me.
That's because I don't believe in USE flags having to be named by the
external dep they introduce, but by functionality. USE=magic sounds
like a USE flag that adds some wizards into your application, automagic
behavior or who knows (until you read the description).
Not that I have a much better suggestion. USE=auto-mimetypes?

The use of term 'magic' for file type recognition by magic bytes is well
established.  Standing on your head and trying to invent an alternative
is not going to help anyone, and only confuse people.

Fair enough.

Completely uncalled for unfriendly hostile additional sentence.

It seems it should also cover, if possible, this to packages that use an
alternative name:

dev-python/jira:filemagic - Include filemagic support (for identifying uploaded
filetypes)
dev-vcs/git-annex:magicmime - Use libmagic to determine file MIME types

I didn't mean to be hostile.  I just meant to visually explain that your
suggestion is long way from the initial point (hence 'standing on your
head'), and it's going to be confusing.

Yes, but `magic` doesn't really gives much of an idea on the feature 
and could get a bit of confusion, I think `libmagic` is better on this 
regard as it's closer to what would be used without much context and 
it's clear that it's about a dependency on sys-apps/file and not some 
kind of magic feature (which is a quite overloaded word in computing).

(auto-mimetype doesn't works at all btw, file/libmagic is much more 
precise than mimetypes)

Fun fact: when I saw this Subject on the ml, I assumed it was probably
going to be a poorly named flag for features provided by ImageMagick.

But I guess that'd be magick, not magic.

"magic" is too overloaded a term :/

Hi Michał,

It looks like you missed two from your original set?

app-editors/nano[magic] Add magic file support (sys-apps/file) to
automatically detect appropriate syntax highlighting
www-servers/pshs[magic] Enable automatic detection of Content-Type using
libmagic (sys-apps/file)

Thanks,
Fabian

I've left them intentionally as they provide more information on what magic support provides.
