error: file not found for module #155

martinlindhe · 2017-03-19T21:13:26Z

Version of VSCode: 1.10.2
Version of the extension: 0.3.10
OS: macOS / Linux

Description: adding a whitespace & save src/main.rs to trigger rustfmt gives error, while "cargo check" sees no error. I dont see this behaviour with other files in the project than src/main.rs

Output of the "Rust logging" channel:

DEBUG: Language Client Manager: start

However, more is shown in the "Rust Language Server" channel:

error: file not found for module `app`
  --> stdin:45:5
   |
45 | mod app;
   |     ^^^
   |
   = help: name the file either app.rs or app/mod.rs inside the directory ""

[Error - 10:09:38 PM] Request textDocument/formatting failed.
  Message: Reformat failed to complete successfully
  Code: -32601

I originally reported this issue in the rls project here, but they tell me their reference plugin doesn't exhibit this behaviour, so I'm re-submitting the issue here.

--

Hello, I am seeing an issue from rls, using the vscode-rust plugin.

I reproduced it on Linux and OSX like this:

git clone https://github.com/BurntSushi/ripgrep
cd ripgrep
code .
[navigate to src/main.rs]
[add a whitespace and save, to trigger rls]

gives the following error:

error: file not found for module `app`
  --> stdin:45:5
   |
45 | mod app;
   |     ^^^
   |
   = help: name the file either app.rs or app/mod.rs inside the directory ""

[Error - 6:01:04 PM] Request textDocument/formatting failed.
  Message: Reformat failed to complete successfully
  Code: -32601

there is a file src/app.rs in the project.
the code compiles correctly using "cargo build".

Intellisense and code navigation appears to work in the other files, this just seems to happen while in src/main.rs

Using rls from git of today (91a4b57), set up like this:

git clone https://github.com/rust-lang-nursery/rls.git
cd rls
rustup update
rustup default nightly
cargo install
# on linux:
export LD_LIBRARY_PATH="$HOME/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib"
export RLS_ROOT="$HOME/dev/rs/rls"

rustup component add rust-analysis

and added the following vscode-rust configuration:

    "editor.formatOnSave": true,
    "rust.rls": {
        "executable": "rustup",
        "args": [
            "run",
            "nightly",
            "rls"
        ]
    },

The text was updated successfully, but these errors were encountered:

I am looking at this issue.

martinlindhe · 2017-03-30T17:20:27Z

I gave this another shot today, rebuilt rls from git master and updated rustup. The issue appears to have disappeared!

@KalitaAlexey Could you reproduce it?

Also I think I forgot to mention i used the vscode-rust version as published in vscode extensions, did not compile this project manually. I see there's been some activity since the last release, possible to tag a new point release?

martinlindhe · 2017-03-30T18:06:29Z

Hm, actually I see it again. Will try to build this extension from source to rule out if recent commits have resolved it.

I think the stdin:45:5 in the original post is a hint. If rls gets piped raw text without context, of course it cannot know about the other modules referenced.

martinlindhe · 2017-03-30T18:23:34Z

Struggling to compile...

$ npm install -dev
$ node ./node_modules/typescript/bin/tsc -p .
$ node ./node_modules/vscode/bin/install
Error installing vscode.d.ts: Missing VSCode engine declaration in package.json.

Not exactly sure how to use all these gulps and npms and typescripts in this particular project.

How would one trigger the creation of a vsix archive to feed into vscode?

KalitaAlexey · 2017-03-31T04:11:56Z

@martinlindhe,
Basically it is enough to run:

npm install
vsce package

KalitaAlexey · 2017-04-19T04:35:40Z

@martinlindhe,
I am closing this issue since there was no any response for a long time.
If you are still experiencing this issue, please open this issue again and details which we discussed.

martinlindhe · 2017-04-19T07:36:25Z

I abandoned use of vscode-rust for the time being because of this issue. Am currently trying out https://github.com/jonathandturner/rls_vscode which is working better, but lacks some other features such as rustfmt. Thanks for your time

KalitaAlexey · 2017-04-19T08:57:27Z

@martinlindhe,
Could you try it again because at some point this extension will be the main one.

cksac · 2017-04-20T15:36:36Z

@KalitaAlexey I have similar issue with RLS mode also..

Version of VSCode: 1.11.2
Version of the extension: 0.3.11
OS: macOS (10.12.4)

rls.toml

build_lib = true

Description:
src/shape.rs exists but get following error when formating src/lib.rs.
while formatting modules(e.g. shape.rs) is fine.

sethlopezme · 2017-04-22T16:06:21Z

I, too, am seeing this issue. The modules that I'm getting an error for are present and I can build my code successfully. This issue appears to happen anywhere there is a mod <module>;.

VS Code 1.11.2
vscode-rust 0.3.11
macOS 10.12.4

# rls.toml
unstable_features = true

// db/mod.rs
use std::env;

use diesel::pg::PgConnection;
use r2d2;
use r2d2_diesel::ConnectionManager;

pub type Pool = r2d2::Pool<ConnectionManager<PgConnection>>;

pub fn init_pool() -> Pool {
    let database_url = env::var("DATABASE_URL").expect("environment variable DATABASE_URL must be set");
    let config = r2d2::Config::default();
    let manager = ConnectionManager::<PgConnection>::new(database_url);
    r2d2::Pool::new(config, manager).expect("unable to create database pool")
}

KalitaAlexey · 2017-04-22T16:45:50Z

@sethlopezme, What OS?

sethlopezme · 2017-04-22T16:47:40Z

@KalitaAlexey macOS 10.12.4

KalitaAlexey · 2017-04-22T16:54:51Z

I am downloading Ubuntu ISO.
I will try this on Linux.
If I the problem didn't occur on Linux, I suppose someone who has Linux would have to do it himself.
Anyway @sethlopezme,
Could you try rls_vscode and say if no problem there.

sethlopezme · 2017-04-22T18:24:20Z

@KalitaAlexey I ran rls_vscode and I didn't see any errors in the output/debug console. I haven't run rls_vscode before but I assume that's where I would look for errors. Let me know if I need to look elsewhere for them.

KalitaAlexey · 2017-04-23T07:06:29Z

@sethlopezme,
vscode-rust and rls_vscode differently start RLS.
I will implement starting as rls_vscode does.

sethlopezme · 2017-04-23T07:37:01Z

I actually had difficulty with rls_vscode. I have RLS installed through rustup, but the only way I could get it to work with rls_vscode was to pull the RLS source down and set the RLS_ROOT environment variable.

KalitaAlexey · 2017-04-23T08:11:33Z

Why couldn't you start RLS from rustup?

sethlopezme · 2017-04-23T15:35:30Z

Well, for a very good reason. The reason being that I'm an idiot and for some strange reason I didn't realize it worked that way. It all makes sense now, ha.

KalitaAlexey · 2017-04-23T18:06:04Z

@sethlopezme,
Will you test a code from a branch which I will tell you?

KalitaAlexey · 2017-04-23T18:09:13Z

The branch is spawn-rls-how-rls-vscode-does
I want you to try it out.
If your problem fixed, I would commit it.
I really hope it will be fixed.

sethlopezme · 2017-04-24T21:37:07Z

Is there anything specific that I need to do? I pulled the repo down, checked out the spawn-rls-how-rls-vscode-does branch and ran it with Debug, but it didn't look like anything was happening. I tried this both with and without RLS running beforehand.

KalitaAlexey · 2017-04-25T04:47:01Z

@sethlopezme,
You should run either extension and try to cause your problem.

sethlopezme · 2017-04-25T05:18:20Z

I guess what I'm asking is if there is anything specific that I need to do to get RLS working on the spawn-rls-how-rls-vscode-does branch. When I tried to use the plugin from that branch, RLS did not appear to start, so I then tried running the plugin with RLS running from the command line, but the plugin still didn't do anything for me - no RLS analysis status in the status bar, no code completion, etc.

KalitaAlexey · 2017-04-25T06:07:01Z

It strange.
It should work.
Could you provide the Output Channel log?

sethlopezme · 2017-04-25T15:25:18Z

Ah, here we go. My apologies - the first time I tried running the extension, I had forgotten to run npm install beforehand. With that being said, I do get an error when trying to run the extension with Debug.

As a reminder, here are my versions:

VS Code: 1.11.2
Extension: latest spawn-rls-how-rls-vscode-does branch
Node: v.7.9.0
OS: macOS 10.12.4

In the Debug Console tab of the main VS Code window, I saw this:

KalitaAlexey · 2017-04-25T16:18:00Z

@sethlopezme,
Pull this branch and try again.
I have no idea how it worked for me)

sethlopezme · 2017-04-25T16:21:54Z

@KalitaAlexey Ah, that allowed the plugin to function for me. I still experienced an issue, though. It saw that I have rustup installed, but it says that I don't have RLS installed (I do, through rustup).

KalitaAlexey · 2017-04-25T17:07:24Z

@sethlopezme,
It showed that it couldn't see RLS
You configured it using rust.rls.
You tried to cause the problem.
The problem happened.
Is that right?

KalitaAlexey · 2017-04-25T17:07:58Z

I have no idea then.

sethlopezme · 2017-04-25T18:06:59Z

I think this is an RLS issue. I was just able to reproduce it in rls_vscode.

KalitaAlexey · 2017-04-25T19:13:50Z

You should open an issue in RLS's repository.
