feat: add actions to reference files, directories and repo maps in IntelliJ Plugin

[vldF]

Description

This PR introduces an ability to reference files and directories in the Continue chat via the project view context action named AddToEditAction. This is a shortcut, so, you can add files manually (via the Continue GUI) or add them with these actions.

This PR also introduces ContinueProjectViewPopUpMenuGroup actions group which is a wrapper for AddToEditAction. This group is needed because 1) it shows that this action is belong to Continue and 2) it is an extension point to the future actions like this one (both points are discussable)

Hello, @RomneyDa, could you please review it?

[RomneyDa]

@vldF looking into this, checking with @TyDunn for product questions

[vldF]

@TyDunn, hello, could you check this one please?

[TyDunn]

@vldF Thanks for the contribution! @RomneyDa I think we will want the right click actions in JetBrains to match what we are doing in VS Code with @uinstinct

[vldF]

@TyDunn, hello!

When I checked similar feature implementation few weeks ago, that kind of implementation was different: in VS Code we can add some file to the context only. My implementation is more useful because we can refer some file (or multiple files, or directory) by name which is useful for some kind of prompts

[vldF]

@TyDunn, @RomneyDa, hello :)

[RomneyDa]

@vldF I'm a big fan of the "add to chat" option but I think we should not add the repo map option, since the repo map provider requires indexing which is being deprecated

I also think we should simplify the messaging to just be "addFilesToChat" or similar and not mix the tip-tap specific mention concept into messaging

[TyDunn]

@RomneyDa If we are going to have second one, then I'd say we also have "Add to Edit", which would make it consistent with VS Code

[RomneyDa]

@TyDunn input appreciated, then I'll adjust review to say

• simplify messaging to be "addToChat" and "addToEdit" (I think this might already exist using add higlighted code or similar)
• remove repo map option and replace with "Add to Edit" option

[vldF]

@RomneyDa @TyDunn if I understand you right, here are changes

[RomneyDa]

@vldF could you update the description/screenshot to reflect changes, or add a comment showing new interface?

[vldF]

@RomneyDa, done. Also, I had reverted addToChat handling due to bug

[vldF]

@RomneyDa, gentle reminder :)

Also, could you please restart failed jobs, please?

[RomneyDa]

@vldF haven't forgot about this one! Need to pull and test.
Just to clarify, ended on only having add to edit?

[RomneyDa]

@vldF current state of the PR seems to mix add to chat and add to edit. The add to chat option calls the add to edit action, etc. Could you take a look? I would either remove add to edit and only have add to chat or make sure both work separately

[vldF]

Just to clarify, ended on only having add to edit?

Yeah

[vldF]

Could you take a look

Sure, I'll do it tomorrow

[vldF]

@RomneyDa, hello. It seems I'm confused in comments above. Could you please give me a short description of both Add to Chat and Add to Edit actions? Is "Edit" in this context an input field of the chat? So, was my initial request about Add to Chat action? If it is true, what Add to Edit action does?

[RomneyDa]

@vldF agreed can be a bit confusing, in both Jetbrains VS Code there are two main actions for selected code:

• Add to Chat - cmd L in vs code, cmd J in Jetbrains - inserts selected code into the chat input
• Add to Edit - cmd I in both - opens Edit mode for a quick targeted edit of the selected code

I think I didn't realize that you were implementing Add to Chat and the only change needed is to change the naming throughout to be "Add to Chat" rather than Add to Edit. Does that sound right?

[vldF]

@RomneyDa, thank you. I have changed the naming in my code

[vldF]

@RomneyDa, hello :)

[RomneyDa]

@vldF thanks for the updates!

[RomneyDa]

Tested, works great!
