vscode-extension | Zeplin for Visual Studio Code

I want to add a language server to handle completion / highlighting / etc. for a file. As a basis for testing stuff I am using an example from Microsoft (https://github.com/microsoft/vscode-extension-samples/tree/main/lsp-sample) and changed it to be active for any File. This language server highlights any word in all capital letters.

When opening a C++ File, I get the highlighting / completion of my language server and the default one for C++ (See image).

I would like to detect if some other extension / build in highlighter is active for a file and deactivate it for this workspace or the current file if it is impossible for the current workspace)

1. Is there a way to do this in a generic way where I do not have to know which extensions are highlighting code?
2. If no, is there a way to do this, if I know a set of extensions I want to deactivate?

I'm trying to use registerInlineCompletionItemProvider proposed API. I'm following the instructions in https://code.visualstudio.com/updates/v1_58 and here https://github.com/microsoft/vscode-extension-samples/tree/main/inline-completions. Both of them ask to copy https://raw.githubusercontent.com/microsoft/vscode/master/src/vs/vscode.proposed.d.ts to your local directory, but that file doesn't exist. Also when I follow the instructions to install the extension I always get an error because it doesn't exist:

I created a VS Code extension which uses a Webview. In the Webview I have a link to a file in the node_modules folder which I added to the html as recommended by various sources (e.g. vscode-codicons-sample):

This is a dump non-vim, non-emacs user question to the users of those editors.

VScode supports such things as decorations of the code:

• color highlight the text ranges
• or insert some helper text content that actually does not belong to the source content but is visible for the user.

Do 1) vim, 2) neovim, 3) emacs support this kind of editor extension?

Someone in my team uses vim, but the rest of us use VSCode's default formatter (i.e. vscode.typescript-language-features). I'd like to add a git precommit hook or something that invokes the formatter without opening up the app.

i recently asked a question "how do i add custom parameters to a custom command in a custom vs code extension" and realized through some of the comments that you cant enter parameters in the command palette. so i looked for alternate options. one i came across was quickInput which allows the user to enter text into a window. however, being new to typescript, along with having documentation for more knowledgeable users on my hands, i couldn't figure out how to use it. please help!

update: since "quickInput" couldn't be found, i decided to opt for "showInputBox" but wasn't sure how to use the "title" parameter. but just for testing porpuses i decided to test the following:

I have troubles adding icons to a TreeItem in my VSCode extension. When I load the extension, the item has a blank space where the icon ought to be.

I have tried to mimic the nodeDependency example. I have the following in extension.ts:

I am new to VSC extension development.

I started with the extension hello world and I want to add an icon to the activity bar and get a notification when it is clicked.

I add these lines to package.json

I am trying to develop a VSCode extension which requires the current open file and same file from previous git revision/commit. Which is same as clicking the open changes button in vs code.

I Tried using SCM and QuickDiffProvider as shown in this sample-extension, but its giving "unable to resolve resource" when trying to open the old file in vscode.
