weirdly inconsistent docs on hover

[413x1nkp]

this lsp is great, but i've been slightly frustrated with the docs feature.

i use it with Helix, and any time i'm hovering cursor over an instruction and then click o to start typing on the next line, i get docs for an instruction i was hovering over thrown in my face. this seems to be happening with call specifically, for some reason. other instructions seem to not do that.

with that said, i do like the ability to get docs of an instruction when i'm hovering over one, but only when i do <space>k (it's a helix default bind to bring out docs), not when i'm just looking at it

i've been mostly using this lsp with FASM and this is the config i have made by gen-config:

[[project]]
path = ""
version = "0.10.1"
assembler = "fasm"
instruction_set = "x86-64"

i got asm-lsp from AUR

i must admit, i'm not really well versed on internal workings of LSPs or Helix, so i may be misattributing the issue, but i don't think Helix has ever done anything like that for me in C. also it's happening only for call instruction of all things, not any other one.

thank you for your time

Could you provide the LSP logs from when this happens? I'm not sure what would be causing this, but the logs should be able to tell us what request the server is responding to.

here are logs coming from helix itself:

from what i can gather, it's making a signature help request because it THINKS that call <FUNCTION> is incomplete(?) same goes for syscall.

so now i'm unsure if it's just an issue with helix itself..

i found a way to disable this helix quirk by adding the following to the config, which works great for me.

[editor.lsp]
auto-signature-help = false

[keys.insert]
C-p = "signature_help"

i still think it's worth investigating further, as this behavior seems to only happen with asm-lsp
