Add prefix argument to Quickopen command (CTRL+P)

[bizoo]

Add an argument (prefix) to "workbench.action.quickOpen" command.
This way you can populate the content with predefined values ("task JS:", "view_", ...) to filter the result using different keybinding.

I think the quickOpenService.show() method has already a prefix argument, so all we need to do is add it to the registered command.

I'd like to take this if no one else started working on it.
Should be a quick fix :)

@bizoo can you please elaborate just a little bit?
Once you press CTRL + P, the command input appears, then what is the next step?
As far as i can tell right now you have the option to view the tasks, recent files, got to symbol and others.

[bizoo]

The goal is only to fill the input with the given argument, everything else must works the same.

Currently when I want to compile my Java code, I type "task Java:" and select the desired item in the list (I have A LOT of task for different purpose).
I like to have a keybinding that open the quickOpen ("workbench.action.quickOpen") and prefill the input with "task Java:", something like (not sure if it's the correct syntax for "args"):

  { "key": "ctrl+alt+j", "command": "workbench.action.quickOpen",
                    "args": { "prefix": "task Java:" }}

Could be used for different purpose, like filter the list of files:
"view_*.java"

Thanks @cristianhosu for looking at it.

edit: There's an example of command with arguments here

@bizoo - finished. Can you have a look? or maybe @bpasero
Thank you

Edit: Still need to get used to working with git.
I've set my upstream and reset my master to the upstream/master and will redo the changes but now on master it throws an error while running:

Hello @bizoo

Args usually represents an array and is treated as such.
Thus, is it acceptable for this issue to be implemented as:

{ "key": "ctrl+alt+j", "command": "_workbench.quickOpen",
                    "args": ["view Git"]}

In the example the args will be an array where the first item will represent the prefix.

@bpasero - can you also validate that this is a valid implementation, or should I create a new class QuickOpenArguments which should contain prefix and showOptions?

[bizoo]

I'm a little bit confused by how args in commands (and keybindings) works.
And as I know next to nothing of VSCode code, I couldn't help.

From this example of "type" command, the argument is named, not an array. If you change the name of the argument of "type" command, it doesn't works anymore.

But example from @bpasero is an array of arguments (couldn't find the implementation of "type" command to compare).
So is arguments of commands and keybindings different ?
