Hello |
| 2 |
|
| 3 |
This comes from this gentoo-dev thread: |

In that one, we try to use the following: |
| 7 |
has vala ${IUSE//+/} && ! use vala && return 0 |
| 8 |
|
| 9 |
as already done in many eclasses/ebuilds. The problem is that Ciaran |
| 10 |
wants to forbid it because he says it's not specified in PMS. My |
| 11 |
suggestion was to simply specify it as it's currently implemented in |
| 12 |
portage because that functionality is (apart of needed) being used for a |
| 13 |
long time in the tree by numerous eclasses/ebuilds, then, from my point |
| 14 |
of view, wouldn't be any sense on lose time for moving them to current |
| 15 |
functionality to a worse one, wait for the next eapi and, finally, |
| 16 |
revert them back to current behavior. |
| 17 |
|
| 18 |
The problem is that I cannot find any doc about how this is currently |
| 19 |
handled in portage. Could you help me on it please? |

Thanks a lot |
