In some cases when attempting to complete using eglot, I am getting errors rather than a list of completions. I haven't been able to debug why but it seems to be happening in "pcm" completion style. For example, in a Rust crate with the following main file: fn foo_len() { } fn main() { len } positioning my cursor after "len" and attempting completion yields the following error message: completion-pcm--merge-completions: Internal error: _mm_blend_epi16(=E2=80= =A6) (use std::arch::x86_64::_mm_blend_epi16) doesn=E2=80=99t match \`len Full backtrace: Debugger entered--Lisp error: (error #("Internal error: _mm_blend_epi16(=E2= =80=A6) (use std::arch::x86_64::_mm_blend_epi16) doesn=E2=80=99t match \\`l= en" 16 17 (eglot--lsp-item (:label #("_mm_blend_epi16(=E2=80=A6) (use std::= arch::x86_64::_mm_blend_epi16)" 0 1 (eglot--lsp-item #5) 5 8 (face completi= ons-common-part)) :kind 3 :detail "unsafe fn(__m128i, __m128i) -> __m128i" = :documentation (:kind "markdown" :value "Blend packed 16-bit integers from = `a` and `b` using the mask `IMM8`.\n\nThe mask bits determine the selection= .

Ok, but please explain exactly what "attempting comp= letion" amounts to. Read the manual about how Eglot bugs should be rep= orted, Emacs -Q etc. Thanks=C2=A0

In some cases when attempting to complete using eglot, I am getting
errors rather than a list of completions. I haven't been able to debug<= br> why but it seems to be happening in "pcm" completion style.

For example, in a Rust crate with the following main file:

fn foo_len() {
}

fn main() {
=C2=A0 =C2=A0 len
}

positioning my cursor after "len" and attempting completion yield= s the
following error message:

Pressing C-M-i with point after 'len' yields the error. The error only happens in partial-completion is in the completion-styles variable, so a workaround is to remove partial-completion from completion-styles, at least in Eglot enabled buffers.

Stefan, this is down to partial-completion somehow thinking that "\\'len" should match at least some LSP-provided completion candidate, otherwise it's an "internal error" I wish I could turn off all the styles from the table but I can only add to them. I simply cannot write a reasonable try-completion thing for LSP completions. LSP completions are really designed to be navigated using a company-like popup. Without it they should almost always use the *Completions* buffer, and rarely ever Emacs partial completion shenanigans. Nevertheless, I need to plug this bug somehow in Eglot.

In some cases when attempting to complete using eglot, I am getting errors rather than a list of completions. I haven't been able to debug why but it seems to be happening in "pcm" completion style. For example, in a Rust crate with the following main file: fn foo_len() { } fn main() { len } positioning my cursor after "len" and attempting completion yields the following error message: completion-pcm--merge-completions: Internal error: _mm_blend_epi16(=E2=80= =A6) (use std::arch::x86_64::_mm_blend_epi16) doesn=E2=80=99t match \`len Full backtrace: Debugger entered--Lisp error: (error #("Internal error: _mm_blend_epi16(=E2= =80=A6) (use std::arch::x86_64::_mm_blend_epi16) doesn=E2=80=99t match \\`l= en" 16 17 (eglot--lsp-item (:label #("_mm_blend_epi16(=E2=80=A6) (use std::= arch::x86_64::_mm_blend_epi16)" 0 1 (eglot--lsp-item #5) 5 8 (face completi= ons-common-part)) :kind 3 :detail "unsafe fn(__m128i, __m128i) -> __m128i" = :documentation (:kind "markdown" :value "Blend packed 16-bit integers from = `a` and `b` using the mask `IMM8`.\n\nThe mask bits determine the selection= .
