Doc of current selection in autocomplete popup doesn't show in Java

JoeHFB commented 3 years ago

Hi vim-lsp folks,

First off, thanks for all the work you guys do.

Could someone help me find what the problem is here? I'm seeing that the floating popup window thing that shows the documentation of the current selection from the autocompletion window is not showing up for Java, even though it IS showing up for python.

Language servers I use

Python: python-language-server
Java: I've tried both eclipse.jdt.ls and java-language-server

Problem

Nothing shows up when there should be a second window with docs for my current selection for Java

What I expected

I would've expected the contents from javadocs to show up in a second window. For the example in the screenshot, this one: https://docs.oracle.com/javase/7/docs/api/java/util/Arrays.html#sort(int[])

As you can see, java-language-server supports this feature so I'm wondering why vim-lsp isn't showing it. https://github.com/georgewfraser/java-language-server#autocomplete-symbols-with-auto-import

Python works... kind of.

weird, but there's two identical popups in different colors 😕 But that's just a minor inconvenience 😄
the docs in that popup seems to be... wrong? I barely ever use python so I'm no python expert, but for the example screenshot above, I would've expected this paragraph, not whatever that is. https://docs.python.org/3.8/library/sys.html#sys.base_prefix

Funny thing is an autocomplete doc from boto3 seems to be correct...

example minimal vimrc I used to reproduce

Can you include logs and see if completionItem include "documentation". some language servers don't send it and we need to do a completion/resolve request but we currently don't do this for documentation. I do plan to add it.

JoeHFB commented 3 years ago

Hi @prabirshrestha -

I did the exact same thing as I did in the two screenshots above after adding

let g:lsp_log_verbose = 1
let g:lsp_log_file = expand('~/tmp/vim-lsp-logs/javalsp.log')

for the two languages.

[~/tmp/vim-lsp-logs]$ ls
javalsp.log  pythonlsp.log

Python:

[~/tmp/vim-lsp-logs]$ rg -i "completionitem" pythonlsp.log

Same thing here - I see "documentationFormat":["plaintext"] but I don't see any field just called documentation

not a bug in vim-lsp.

JoeHFB commented 3 years ago

Hi @prabirshrestha -

I tried this again with eclipse.jdt.ls, and it looks like in the logs the server IS returning documentation. To confirm, is this that vim-lsp isn't accounting for another place where docs can be returned? Or is this a server issue that they're returning the documentation in the wrong spot?

If it's a vim-lsp extension that's needed, I'll submit a new issue.

As you can see, no documentation popup

In the logs it seems like documentation is attached in the response from LSP

screenshot

Comparing this to the javadocs, the documentation does look correct: https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#compareTo(java.lang.String)

If they have different characters at one or more index positions, let *k* be the smallest such index; then the string whose character at position *k* has the smaller value, as determined by using the `<` operator, lexicographically precedes the other string. In this case, `compareTo` returns the difference of the two character values at position `k` in the two string -- that is, the value:\n\n>     this.charAt(k)-anotherString.charAt(k)\n\nIf there is no index position at which they differ, then the shorter string lexicographically precedes the longer string. In this case, `compareTo` returns the difference of the lengths of the strings -- that is, the value:\n\n>     this.length()-anotherString.length()\n\nFor finer-grained String comparison, refer to java.text.Collator.\n\n *  **Parameters:**\n    \n     *  **anotherString** the `String` to be compared.\n *  **Returns:**\n    \n     *  the value `0` if the argument string is equal to this string; a value less than `0` if this string is lexicographically less than the string argument; and a value greater than `0` if this string is lexicographically greater than the string argument."},"detail":"String.compareTo(String anotherString) : int"}},"request":{"id":27,"jsonrpc":"2.0","method":"completionItem/resolve","params":{"label":"compareTo(String anotherString) : int","data":{"uri":"file:///home/joe/code/java-language-server/src/main/java/org/javacs/LogFormat.java","pid":"6","rid":"1","decl_signature":"Ljava.lang.String;","signature":"(Ljava.lang.String;)I","name":"compareTo"},"textEdit":{"range":{"end":{"character":15,"line":17},"start":{"character":15,"line":17}},"newText":"compareTo"},"sortText":"999999035","kind":2,"insertTextFormat":1,"insertText":"compareTo","detail":"String.compareTo(String anotherString) : int"}}}]
