Autocomplete: Tab behavior

[vicb]

It would be great that tab stops after the first ":" where different commands are possible.

IE after "doct", tab should stop on "doctrine:"

[laszlokorte]

This is how I implemented it in a really early version but I did not like it because there is already a command selected in the suggestion list so when you press tab I would assume this selected command is used.

When I type "doc" and the first suggestion is "doctrine:cache:clear-metadata" and it is selected (given the behavior you suggest is implemented) I would need to press tab 3 times.

One possibility would be not to focus a suggestion by default and only use your suggested behavior when no suggestion is selected but I assume that would not be very intuitive because there would be more different cases of behavior.

Do you have a concrete case in mind in which the behavior you suggest would be easier to use?
I mean when typing "doc" you already see all the doctrine commands.
I assume it is about this case:

you want to use the "doctrine:cache:clear-result" command and want to type:
"doc"[tab]"ca"[tab]"clear-result"
so you save the time writing "trine" and "che".

But the much easier way would be to just write "clear-result" in the beginning as the autocompletion does not force you to start on the left side of the command.

[vicb]

"doctrine:generate:entities" could be a good example. If I wan to use this comand, I would like to be able to type:

• "doc"
• tab
• "ge"
• tab
• "ent"
• tab

One possibility would be not to focus a suggestion by default and only use your suggested behavior when no suggestion is selected but I assume that would not be very intuitive because there would be more different cases of behavior.

👍 for this. I assume that you would rarely use the first command anyway (especially true when you have a lot of commands, like in the "doctrine" ns).

I think the most "difficult" part of the PR it to avoid unambiguous stops:

• "namespace:sub:abc"
• "namespace:sub:def"

"nam" + tab should autocomplete to "namespace:sub:" as this is not ambiguous.

[laszlokorte]

What should happen wenn I type:
"c"
tab

I could autocompelete to "cache:" or "config:" or "container:"

Currently the autocompletion list also shows all the doCtrine commands as suggestion too.

[vicb]

Ideally I think you should stop autocompleting where the completion becomes ambiguous (multiple solutions). This would match the behavior of terminals. To continue either select a (sub)command or type more letters.

That's would be the best thing to have imo but something different would be ok if this makes the code too complicated.

Ok...

I have started implementing this a separate branch:
https://github.com/CoreSphere/ConsoleBundle/tree/alternate-autocomp

When the input is ambiguous the old behavior is used:
focus first item in autocompletion list

When the input is the prefix of exactly one namespace:
no suggestion is focused and pressing tab triggers the autocompletion up to the next ":"

I won't have time to look at it before next friday.

Is this still active? If not, I'd suggesting closing.

In case of interest, PR is welcomed of course.
