Shown suggestions are for all objects/classes

[ManuGraiph]

Hi,

I'm new to blink, just installed it and i have a question.. i was expecting basically to get the dir() suggestions for an object, but blink suggests me, for autocompletion, ALL the methods/classes/functions/etc. available, not only the ones for the object in the current position.

Example.. here i'm getting the suggestions for a QWidget object, in python, and i get every method available (numpy/pytorch ones, custom functions, methods of other objects, etc.)

Is this just a configuration thing or this is how it works?

Thanks in advance!

What lsp are you using for this? And please post your blink.cmp config. What shown in the screenshot seem, likely, buffer source results not lsp.

Probably, tbh, i have no clue how to config either the cmp engine or the lsp, i just started with this a couple hours ago. I took the config from some random stackoverflow post:

lua << EOF
require('blink.cmp').setup({
  keymap = { preset = 'default' },
  appearance = { nerd_font_variant = 'mono' },
  completion = { documentation = { auto_show = true } },
  sources = { default = { 'lsp', 'path', 'snippets', 'buffer' }, },
  fuzzy = { implementation = "prefer_rust_with_warning" }
})
EOF

I use init.vim, so i had to head it.

Basically, you need to install an LSP server that match your language and attach it to your buffer. blink.cmp will be aware of that and will query your LSP to get the corresponding completion candidates (if the LSP returns no result, the buffer source will take over).

For Python with Qt specifically (like your QWidget example), you should install a Python language server like pyright, pylsp, zuban, pyrefly, ty... refer to their repo to see the difference, pick one you like, e.g. pip install pyrefly

Then you need to let neovim be aware of this lsp and attach it whenever you open a buffer matching that language, see :h lsp. Use nvim-lspconfig if you want to configure automatically or manually pick the one you want in their repo at https://github.com/neovim/nvim-lspconfig/tree/master/lsp and adapt it to your liking in your lsp/ folder.

You can also look at kickstart.nvim that is a good resource to know how things fit together. Good luck :)

Yep, i have pyright and nvim-lspconfig installed, and i have it enabled in my init.vim with:

lua << EOF
  vim.lsp.enable('pyright')
EOF

But same behaviour

[soifou]

And pyright is attached to the current buffer, right? Check with :LspInfo or directly with :=vim.lsp.get_clients({ bufnr = vim.api.nvim_get_current_buf() }).

[ManuGraiph]

Yep, it shows me the warnings at the left side of the line numbers.

I think i'm missing a setting for the lsp; how can i tell the lsp to only make suggestions for the current object i'm in and not like for all the imported libraries?

[soifou]

Did you set correctly the LSP capabilities? You did not mention your nvim version. See https://cmp.saghen.dev/installation.html#lsp-capabilities

[ManuGraiph]

Nothing in that link shows me how to set the lsp or blink to only show the object methods.

[ManuGraiph]

Nop, i haven't configured anything in the lsp (hence, that's'why i think the issue is there) i just enabled it with the line mentioned above.

Do yo have lsp installed in your machine?? From the you screenshots you have given, blink is only catching buffer completions, not lsp ones. What does cheackhealth vim.lsp says?? With this minimal config and pyright installed, I can't reproduce your issue,

vim.pack.add({
	"https://github.com/neovim/nvim-lspconfig",
	"https://github.com/saghen/blink.cmp",
})
vim.lsp.enable("pyright")
require("blink.cmp").setup({
	keymap = { preset = "default" },
	appearance = { nerd_font_variant = "mono" },
	completion = { documentation = { auto_show = true } },
	sources = { default = { "lsp", "path", "snippets", "buffer" } },
	fuzzy = { implementation = "prefer_rust_with_warning" },
})

[ManuGraiph]

Sorry, i think i mentioned it, i have pyright installed. Do i have to configure something extra for it or just install it?

[ManuGraiph]

Mmm, just ran a checkhealth:

vim.lsp: Active Features ~

vim.lsp: Active Clients ~
- No active clients

vim.lsp: Enabled Configurations ~

vim.lsp: File Watcher ~
- file watching "(workspace/didChangeWatchedFiles)" disabled on all clients

vim.lsp: Position Encodings ~
- No active clients

So, indeed it's not connecting to the lsp.

I just installed pyright, am i missing something to getn the lsp running?

[asadzman]

add this line vim.lsp.enable("pyright") to your config and restart. And then open a python project. Now lsp should auto attach

[ManuGraiph]

I do have that line, my config is literally the same as yours.

I reinstalled pyright, now it's detecting it, but the behaviour is exactly the same, showing me all the possible matching keywords for everything.
