How do we merge this with adhearsion-asr / Adhearsion core?

[benlangfeld]

Adhearsion-asr cannot be merged into Adhearsion core until Adhearsion 3.0 since it changes the API of core #ask and #menu methods on CallController.

Particularly #menu is a candidate for closer integration with this gem.

So, it's plausible that we could merge some parts of adhearsion-asr into Adhearsion core prior to Adhearsion 3.0: the settings, the PromptBuilder and the Result structure. We could not include the #ask and #menu controller methods, since they are the parts which are not backward compatible. There would not be a benefit to including either the AskGrammarBuilder (used to build grammars from :limit options to #ask) or the MenuBuilder (implementing the menu DSL, including grammar construction from #matches, retries, error/failure handling and invocation of #matches).

Merging these pieces into Adhearsion core would reduce the future effort required to merge adhearsion-asr into core, allow adhearsion-ivr to function without depending on adhearsion-asr, and thus allowing adhearsion-ivr to be merged in to core in the Adhearsion 2.x series, if this were desirable.

Additionally, in its current form, this gem provides similar functions to #ask. What it does not provide from adhearsion-asr is simple support for built-in grammars for common cases (from #ask, eg yes/no, DTMF grammars with digit limits or unlimited input up to a terminator) or automatic grammar construction from a list of possible options (from #menu, similar to VoiceXML Menus).

These features do not help the case for a merge into Adhearsion core, but would permit absorbing adhearsion-asr such that #ask and #menu might be deprecated entirely from Adhearsion core and maintained solely in adhearsion-asr, should we decide that this whole-controller implementation was preferable going forward.
