I would love to have this feature. I have wanted this for OCaml, where
the default imenu index produced by the "merlin" tool is annoyingly
deeply nested, which makes it awkward to use.
I have an alternative proposal though, which might be better: We could
enhance the imenu completion table to understand completion boundaries.
Then the imenu hierarchy could be completed over in a single
completing-read instead of a sequence of multiple completing-reads. It
would work the same way as read-file-name.
So, for example, if the completion boundary was /, and we had a hierarchy
containing these elements:
aaa/bbb/ddd
aaa/bbb/eee
aaa/ccc/eee
aaa/ccc/fff
You could choose aaa/bbb/ddd with this sequence of minibuffer contents:
(input in [brackets], point at |)
[a]
a|
[<TAB>]
aaa/| ; completion now shows bbb and ccc as options
[b]
aaa/b/d|
[TAB]
aaa/bbb/ddd|
[RET]
Alternatively, you could choose aaa/bbb/eee with this sequence:
[*/*/e]
*/*/e|
[TAB]
aaa/|/eee ; completion now shows bbb and ccc as options, point is at |
[b]
aaa/b|/eee
[TAB]
aaa/bbb/eee|
[RET]
To be very clear, these completion features already exist (and are
enabled by default!), all we would need to do is enhance the imenu
completion table to understand completion boundaries, and then imenu
would have access to these features too.
This new completion table could be turned on by default, since it would
be strictly more powerful than the current imenu UI.
Plus, if some alternative completion UI wanted to flatten the hierarchy
anyway, this more advanced imenu completion table would allow that.
