If I type :

And press [esc], then the whole name appears. Nevertheless, if I try with ab-, then the completion doesn't trigger. So far I experienced, I works only after alphanumeric characters.
Thus, there are two strange behaviours :
1. The entity scopes don't seem to affect autocompletion. Then, what is the recommended manner to solve my main issue ? Can I capture the function name in both selectors (entity and variable) ?

What you can do is set a characterClass for the entity scope.

For example in the bundle editor create a new settings item and make the scope selector be entity.name.function.scheme and the actual value something like: { characterClass = 'variable'; }.

Now TextMate will treat all contiguous characters matched as entity.name.function.scheme as a single word for the purpose of word selection, completion, etc.

2. Why can't the autocompletion be triggered after a non alphanumeric character ?

This is because TextMate only completes “words”, however, as you can define what constitute a word, you can include the dash.

For example if you do the above setting then escape will complete if the dash is used in a place where it is matched as entity.name.function.scheme.

There is also the ability to simply make the dash a word character for the source.scheme scope, this would also be done by a bundle setting but one that is scoped to source.scheme and contains { wordCharacters = '-'; }.
