Auto-complete some words

[Hywan]

Hello :-),

I think it would be great to use Hoa\Console\Readline\Autocompleter\Word to autocomplete some words, like $asserter, integer, float and all the asserters.

Thoughts?

+1 : I'm trying to find some good rules to let autocompleters handle eveything.

For example :

• if the line begins with $asserter we complete with atoums assertions
• if the line begins witha ! we complete with native shell commands
• if the line begins with a : we complete with atoum-shell commands
• ...

Do you want one autocompleter or aggregated ones?

[jubianchi]

the shell works a bit differently at the moment: it uses a "late-binding" strategy : autocompleters are not bound when the shell boots.

The only completer I bind is the following : https://github.com/jubianchi/atoum-shell/blob/master/classes/input/completer.php

This one acts as a dispatcher, delegating the completion to the appropriate command. So I don't think I need an aggregate for now. At least, I don't need it until I refactor the way it's handled.

For now, I thnik each command will provide his own completer depending on what it has to complete:

• for $asserter-, :- and !-prefixed commands, I'll use a word completer
• the other will likely be handled by a path completer

A command could also provide more than one completer, depending on what the user typed. For example, the :foo command could take a path as its first argument and the something that is word-completed so it will dynamically change its own strategy, providing a different completer depending on the user current input.

The Hoa\Console\Readline\Autocompleter\Aggregate acts like your custom completer. It works with a collection of autocompleters and tries to find the one that is able to autocomplete the current prefix. I wonder if it is possible to create an aggregation of aggregated autocompleters. Possibily yes. The highest aggregation would have .* as the word definition. Then, another aggregation will have: ^\$asserter->.*, with Word and other autocompleters etc.

But I think that a simpler solution would be to solve hoaproject/Console#10. Thoughts? Would it fit your needs? Based on a pattern, we autocomplete “places” (this is how I see it), similarly to Zsh.

@Hywan I have to give a try on using the new aggregated autocompleter to see if it fits. If yes, I'll use it ;)

I'll keep you updated ;)
