VSCoq doesn't seem to work properly (doesn't interpret code).

Reproduction

(click to expand)

Save the following into ~/a_days_of_the_week.v:

Inductive day : Type :=
  | monday
  | tuesday
  | wednesday
  | thursday
  | friday
  | saturday
  | sunday.

Definition next_weekday (d:day) : day := 
  match d with
    | monday => tuesday
    | tuesday => wednesday
    | wednesday => thursday
    | thursday => friday
    | friday => monday
    | sunday => monday
    | saturday => monday
  end.

Compute (next_weekday friday).

Open with VSCode:

$ code-oss ~/a_days_of_the_week.v
node[27056]: pthread_create: Invalid argument
$

View, Open View…, Coq Language Server:

node[27742]: pthread_create: Invalid argument

Run command “Coq: Interpret to End” (Alt-End), then view output:

Compiling and running the code through coqc works fine:

$ exa -l | rg a_days_of_the_week
.rw-r--r--  381 a 28 May 0:10 a_days_of_the_week.v
$ coqc ~/a_days_of_the_week.v
     = monday
     : day
$ exa -l | rg a_days_of_the_week
.rw-r--r-- 1.4k a 28 May 0:14 a_days_of_the_week.glob

I have exactly the same problem, the extension tells me “coqtop is not running” and do nothing. I’m using Manjaro linux in wsl2.

Are you having the same problem that it complains about “invalid argument”? “Coqtop is not running” is not an error, it’s just stating the fact that you haven’t started coqtop yet. Have you tried stepping in the file? Like Coq: Step Forward (obtained after opening the command palette)?

Oh, it now works perfectly. I thought it was an error. Thanks very much.
