Cannot jump to definition

[GGXBoo]

I remember that it was possible to press and hold Ctrl and then use click to jump to the defined place, but now it can't.What's going on?

[googleson78]

It still works for me. Can you provide more information? Version of hls, what editor+LSP client you're using, what cradle you're using, what actions you're taking, a log from lsp, etc.

Can you also provide a log from hls when the action doesn't work?

And I just found another problem. I defined a function in a file, and then changed its type. When using this function in another file, the type is still displayed before modification.

jump/go to definition should work for local package definition but for now it does not for libraries definitions (Data.List, Data.Maybe, Data.ByteString, etc), see https://github.com/haskell/ghcide/issues/61
It works for me too in windows (for local ones), did you tried for local or external defs?

Here is the definition of jump local package， not to the library definitions (Data.List, Data.Maybe, Data.ByteString, etc).

Another problem is that the function type I defined in other local files will be modified later. When the function is used in other files, the type is still before modification.

@GordonGgx Maybe it can be related to #478? After upgrading HLS from 0.4.0 to 0.5.x, jump to definition and descriptions on hover stopped working for me as well, and upgrading stack from 2.3.3 to 2.5.0.1 (release candidate) fixed all the issues for me.

well, I am try it.

Only note that it is a difference between got no server response at all, not hover, no goto def, etc, and only miss one of the features.
First one usually is due a problem with server initialization and setup.
