Please answer these questions before submitting your issue. Thanks! Also, remember that to restart gocode, you have to run gocode close.

Description

I substitute mdempsky/gocode with this one in ycmd. I also added -source option for external package completion. It almost works besides when I first open a go file and complete some external package, it will fail with no completions found error. After several (~3 times) retries, it works.

I'm not able to reproduce this when opening files, but if you are opening new Go files, perhaps you are encountering https://github.com/stamblerre/gocode/issues/3?

No, sometimes when the external package is big/complex, it seems will fail. I think it is caused by some different reason. I don't know how to get the error from vim/ycmd (even i added -debug option for gocode, the output from ycm seems have no help).

stamblerre commented 5 years ago

To get the debug output, you will have to start gocode manually. 

$ gocode close
$ gocode -s -debug

Then you should be able to open up Vim and type normally, and the completion output will show up in terminal.

Where should the -source option be added for external package completion?

stamblerre commented 5 years ago

-source is necessary to type-check packages from source (rather than export data from a build), so it shouldn't be necessary for external packages to be completed. The -source flag should be provided on the client side, so you will have to configure it in your editor settings.

Closing this issue, as the current recommendation for autocompletion is to use gopls.
