Vscode-rust: Including a build.rs breaks plugin functionality
When my project includes a build.rs referenced in the Cargo.toml the error output and Problems panel of this plugin no longer works.
Information
VSCode version: Version 1.18.1
Plugin version: 0.3.2
OS: Arch Linux
Steps to reproduce
- Create a new project with
cargo new --bin my_test - Open VSCode in that directory
- Add some code that will cause a problem (this works):
fn main() {
let a = 5;
a = 12;
}
- Now add a
build = "build.rs"to theCargo.tomlfile which contains some code (my example) - Now the
Problemspanel no longer updates. New problems will also not be highlighted
Not sure if I'm doing something wrong here but I think this is a bug 馃槖

I guess I can confirm your issue. Same versions, Arch and Ubuntu 17.10. I first assumed I was hit by #188. There is nothing on the error console and no suspicious output in the rls debug file, I presume, like in my case?

Using default RLS will not work with build script, as this is something that requires more info about inter-package dependencies. This should work with "rust.workspace_mode": true and "rust.unstable_features": true, however.
@spacekookie could you try turning those on and see if it helps?

@Xanewok : It doesn't work for me using these options. I'm using:
{
"rust.workspace_mode": true,
"rust-client.logToFile": true,
"rust.unstable_features": true,
"rust-client.channel": "nightly-2017-11-15-x86_64-unknown-linux-gnu"
}

@oleid Damn, beat me to it 馃槈
@Xanewok It doesn't work for me either
Here is the settings I'm using
{
"rust.workspace_mode": true,
"rust.unstable_features": true,
// ... unrelated stuff ...
}
@spacekookie It was quite close. Fortunately, this is not a competition :)
I forgot to mention: I don't see any errors in rls's log file, but something like:

Which looks okay to me. For the record: I'm building a c++ based library using cmake in the build.rs file and wrap it using bindgen.

well yeah, it definitely should show these 2 warnings and 3 errors. I'll take a look, but in the meantime, could you reload the vscode with the workspace_mode on and see what are the logs then? Preferably rerunning vscode with RUST_LOG=rls=trace env var set.

@oleid since we're having this remote co-debugging session already :smile: would you mind trying to get the library to compiling state, then reload the vscode with the workspace mode on? It may be possible that the first run is crucial for the mode to work later and I'd like to verify that hypothesis here

Indeed, if the project compiles successfully, I get warnings in the editor.
oleid
on 29 Nov 2017
@oleid even after you subsequently modify build.rs or other files, after the initial successful compilation?

Nope, adding an error, the editor doesn't highlight the newly introduced problem. I added something like

same issue here. with build.rs, it properly reports issues and errors when first load. after make any changes, the rls status icon spins forever. the workspace_mode and unstable_features make no difference.

Workspace mode has been turned on as the default for quite some time now and this should Just Work^tm. Do you still have any issues with that?

When build.rs has a syntax error, the whole Cargo.toml is highlighted with no useful message.
Also it does not format build.rs even if it compiles.
