Isn't it the time to make a new EAPI which no longer has USE "flags" but |
| 28 |
USE "values" ? Many of the really weird USE flags combinations would be |
| 29 |
much more clearly expressed if the possible types for a USE variable |
| 30 |
were: |
| 31 |
1) member-of: for choosing the backend of certain functionality; e.g. |
| 32 |
all combinations of USE="ssl openssl gnutls nss" would become e.g. |
| 33 |
in the ebuild: |
| 34 |
USE="ssl=[member-of: openssl,gnutls,nss]" |
| 35 |
in make-conf: |
| 36 |
USE: ssl=openssl, as synonymous of old USE="ssl openssl", or |
| 37 |
USE: ssl=none, as synonymous of old USE="-ssl" |
| 38 |
2) subset-of: for selecting a number of modules to build. This would |
| 39 |
replace USE_EXPAND quite neatly |
| 40 |
3) boolean: as alias for member-of: [true,false] |
| 41 |
4) unsigned int: IIRC some (few) packages can take optional uint at |
| 42 |
configure-time. for example with dev-lisp/sbcl one can customize some |
| 43 |
hardcoded GC parameters suchs as the default heap size, generation size, |
| 44 |
etc... |
| 45 |
|
| 46 |
In the above case, one could have a USE variable named "webkit" of type |
| 47 |
member-of: [qt,gtk] |
| 48 |
