No, because ffmpeg here is a feature AND name of concrete realization. |
| 33 |
Not ideal case as i would said, but it is acceptable. |
| 34 |
|
| 35 |
You want to migrate to such decision? Like: |
| 36 |
|
| 37 |
qt? ( |
| 38 |
qt5? ( dev-lang/qtcore:5 ) |
| 39 |
!qt5? ( dev-lang/qtcore:4 ) |
| 40 |
) |
| 41 |
|
| 42 |
Fine by me, if you would ask. |
| 43 |
|
| 44 |
As i said one message earlier: Something like $(qt_use_default qtgui 5) |
| 45 |
|
| 46 |
which will generate something like this: |
| 47 |
|
| 48 |
qt4? ( |
| 49 |
qt5? ( dev-lang/qtcore:5 ) |
| 50 |
!qt5? ( dev-lang/qtcore:4 ) |
| 51 |
) |
| 52 |
!qt5? ( !qt4? ( dev-lang/qtcore:5 ) ) |
| 53 |
|
| 54 |
would help too. |
| 55 |
|
| 56 |
If you are doing complicated things(and please, do not tell me that |
| 57 |
provided dependency string is simple and understandable by every |
| 58 |
developer in just a second without wanting to "improve" or "simplify" |
| 59 |
it) - do it through eclass. And provide nice API. |

Thanks for listening and sorry if i was too harsh |
