Embed CPP Code completion into custom DSLs with cpp with snippets.

Rajsmit commented 4 months ago

We are currently trying to add code completion support for the CPP code fragment inside the custom art language in Project Code Realtime (https://github.com/secure-dev-ops/code-realtime)

We are using Request forwarding concept to get the code completion from installed extension which support CPP language (clangd) . We already tried to setup Request-Forwarding to use the existing CPP language support provided by the clangd.

Unfortunately vscode.executeCompletionItemProvider command does not work as expected if the file is not opened and focus at least once in the VS Code IDE. If file is opened and focused then the code completion returns expected items but if the file is not opened it does return items which are global in nature and not specific to current position where user is interested for code completion.

I am attaching the screenshot for both scenario and logs for analysis.

CPP file not opened in IDE(returns random code completions)

Here is a previous issue that contains some discussion that may be relevant: https://github.com/clangd/vscode-clangd/issues/440

Hi @HighCommander4 ,

I tried with the suggestion to open the file CPP file in background using vscode API "vscode.workspace.openTextDocument" and it does trigger "textDocument/didOpen" on the file and then calling the code completion API. The code completion works only after first try. In the first try it returns some identifiers. I also activated the extension "llvm-vs-code-extensions.vscode-clangd" before i hit the code completion API. Could you please have a look and check what could be the issue? here is the log of first and second try

I believe the reason for this is that clangd tries to respond to completion requests with low latency. When a file is opened, clangd starts parsing the file contents into an AST in the background. If a completion request arrives before the parsing is complete, clangd answers the completion request based on the project's index only. If the AST is ready when the completion request arrives, clangd answers the completion request using both the AST and the index.

In your case, the first request is received before the AST is ready, and the second request is received after.

Clangd actually has a command line option to control this behaviour: --completion-parse=always makes completion requests block until the AST is ready. With that, you should get the desired results on the first request.

Hi @HighCommander4 , Thanks for the information with the above argument --completion-parse=always to clangd. I am able to get the code completion from first request onwards.

Thanks for the great help.
