Telescope lsp_workspace_symbols not functioning

[jacksonludwig]

Description

:Telescope lsp_workspace_symbols not functioning.
Expected Behavior

:Telescope lsp_workspace_symbols launches the finder and displays the workspace symbols sent from the LSP.
Actual Behavior

:Telescope lsp_workspace_symbols has no effect; it is as if :Telescope lsp_workspace_symbols is an unrecognized command. This is the case even when the LSP supports workspace symbols, e.g. :lua vim.lsp.buf.workspace_symbol()<CR> works.

Details

Reproduce

1.) Use simple test.vim config
2.) Go to a python project (or any other language/LSP if you prefer)
3.) Run :Telescope lsp_workspace_symbols

Thanks for reporting. pyright expects a query. I have already a PR ready that prints a message in that case. I am about to merge that PR :)

For now: Telescope lsp_workspace_symbols query=something should work. We just use a empty string as query and most servers will show all workspace symbols in that case but pyright and clangd don't

[jacksonludwig]

Alright, that would make sense. However, in three LSPs I've used (tsserver, gopls, and pyright) I still get this issue even with query=something, just to be clear. @Conni2461

In the past I called vim.lsp.buf.workspace_symbol() with an empty string and it worked just fine with telescope set as the handler.

[jacksonludwig]

Welp... regardless your PR fixed the issue XD, thanks and ignore my last comment

[Conni2461]

Can't comment for tsserver and gopls but pyright just worked for me. I tested that 🤣
I don't know what the specification says for an empty string.

Good to hear that this fixes your issue :)

[ranjithshegde]

btw the issue still exists for ccls. Same error as above

[Conni2461]

@ranjithshegde yeah because this issue isn't fixable from our side. ccls, clangd and probably more are not returning results for an empty query.
So what i am doing is i have this mapped:

lua require'telescope.builtin'.lsp_workspace_symbols({ query = vim.fn.input("Query >") })

So if i know that my lsp accepts an empty query like sumneko i just press enter again and if not i can type in my query

[Conni2461]

I am thinking about a live grep version of workspace_symbols lately. Maybe something like this could solve that problem.

Maybe @oberblastmeister async PR can make a live_workspace_symbols possible. Just thinking out load

[ranjithshegde]

lua require'telescope.builtin'.lsp_workspace_symbols({ query = vim.fn.input("Query >") })

Thanks. that worked like a charm. I just changed it to query = vim.fn.expandd ('<cword>') to get symbol under cursor

Live grep sounds nice!

Please do, this is one of the major advantages of coc.nvim

@ranjithshegde @eulertour live_workspace_symbols is here! #705
