This adds basic support for the new rustc error format used in recent nightlies. It appears to be working, but it's possible I've missed some edge cases, so comments are welcome.

Also, I'm not at all familiar with syntastic or how it works, so I haven't tested that part yet. If someone who uses that plugin could give this a try and let me know if it's broken, that would be great.

So, I have some weird issues when saving files using rust.vim. Whenever I changed a file and want to save it, vim displays the whole file in that scrollable mode (--- More --- at the bottom line, scrolling with arrow keys) and only when I scroll to the bottom, the file gets saved. This does not happen without rust.vim.

I use pathogen and have nerdtree, youcompleteme, syntastic and rust.vim in my bundle folder.

This PR builds on PR #72 .

There's a new option to choose between fast lint (parse-only) or comprehensive (no-trans). You can change this at runtime too.

Possible improvements include a buffer-local variable so that you can have different projects with different linting levels.

Hi,

when I run :RustFmt on a file under macOS Mojave it takes over three seconds for it to complete. Running the same on the command line completes instantly:

I'm opening this issue just to get some visibility of people that are both Rust user and VimL-versed.

https://github.com/neomake/neomake/issues/1916

Let's say you have project a with a/b subcrate.

If you cd a/b and vim, neomake stops working well, because rustc still displays error paths as b/src/lib.rs (relative to workspace root) while neomake/Vim would like them to be relative to current dir, so just src/lib/rs.

All it takes to fix (I think) is fixing the path somewhere here: https://github.com/neomake/neomake/blob/master/autoload/neomake/makers/ft/rust.vim#L136 by stripping the prefix.

But it's currently beyond me, how to do it right, and I don't have time to dedicate to figure it out.

Please, someone take a look. :)

Hi there !

As cargo check has been merged in cargo (see https://github.com/rust-lang/cargo/pull/3296), and the current rustc checker is facing some issues with external crates (see https://github.com/rust-lang/rust.vim/issues/130), I gave a try implementing a cargo checker for syntastic.

And here is the result. Please note it is my first time writing a syntastic checker, and I'm relatively new to the rust ecosystem, consequently I might have made mistakes, so any feedback will be greatly appreciated !

It currently works with cargo 0.16.0 nightly.

Thanks !

hi, syntastic gives me wrong error messages. the code compiles fine with cargo though.

I have my own crate with submodules. when in submodule1 I import some class from submodule2 with "use submodule2::MyClass"; syntastic launches rustc -Zno-trans src/submodule1.rs which results in unresolved imports (E0259). I asked on irc about that and they told me I should compile the whole crate using cargo and not just the single file.

In vim's official filetype.vim, I found that in line 860:

au BufNewFile,BufRead *.vc,*.ev,*.rs,*.sum,*.errsum setf hercules

Maybe it is better to move ftdetect to after/ftdetect?

I use Plug (Plug 'scrooloose/syntastic'), Syntastic is enabled but no response when I save a Rust file that contain many errors...

I use Neovim (NVIM 0.1.5) on macOS.

This is the output for :SyntasticInfo, for a Rust source code:

Syntastic version: 3.7.0-224 (Vim 704, Neovim, Darwin)
Info for filetype: rust
Global mode: active
Filetype rust is active
The current file will be checked automatically
Available checker: rustc
Currently enabled checker: rustc

Also, when I manually enter :SyntasticCheck, no output...

Current Rust compiler: rustc 1.11.0 (9b21dcd6a 2016-08-15).

If anyone have an idea about what's wrong here, please to comment! :-)
Thanks

Steps to reproduce:

1. Open a rust buffer

2. Open a second rust buffer See error message:

   Error detected while processing function delimitMate#Get..<SNR>74_get:

   E15: Invalid expression: s:options.3.excluded_regions
   

3. Open a third buffer See error message:

   Error detected while processing function delimitMate#Get..<SNR>74_get:                                                                  
   line    7:                                                                                                                              
   E716: Key not present in Dictionary: 4.excluded_regions                                                                                 
   E15: Invalid expression: s:options.4.excluded_regions
   

4. And so on...

This migrates this repository from using the highfive bot to using triagebot (aka rustbot).

This is ready to merge now, feel free to merge to re-enable auto-assignment.

While as is functionally an operator, it is often highlighted as if it were a keyword. This change gives the user the option to link rustOperatorKeyword to Keyword while preserving the current default behavior. This allows for as to be highlighted like a keyword separately from other operators.

The documentation lists as as a keyword and consistently highlights it as such.

https://doc.rust-lang.org/std/index.html#keywords https://doc.rust-lang.org/std/keyword.as.html

Rust compiler output

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

did not ignored due to errorformat was set \%Inote:\ %m first. So, change += to ^= solve this problem.

And, more cargo test cmmand output error: test failed, to rerun pass ... should be ignored.

I wish this change would apply to vim repository. In vim repository, compiler/cargo.vim is not up-to-date, so we cannot parse error correctly.

rust.vim version:

I installed the plugin with Vundle. The current commit of the repository it cloned is: commit 4aa69b84c8a58fcec6b6dad6fe244b916b1cf830 (HEAD -> master, origin/master, origin/HEAD)

Steps to reproduce:

In terminal: vim hello.rs In vim: :w

Expected vs. actual behavior:

• Expected: save the file
• Actual: editor exits with the following error message:

[4]+  Stopped                 vim hellp.rs
exit
There are stopped jobs.

Running ls -a reveals that there is still a file called .hellp.rs.swp

Paste debugging info from the Rust Vim plugin via one of the following

commands: :RustInfo, :RustInfoToClipboard, or :RustInfoToFile <filename>.

Running any of the commands listed causes a crash similar to the one caused by saving the file.

• rust.vim version: Latest from git (4aa69b84c8a58fcec6b6dad6fe244b916b1cf830)

Steps to reproduce:

• Create a new Cargo project.
• Create a file rust-toolchain containing:

[toolchain]
channel = "nightly-2022-06-30"
components = ["cargo", "llvm-tools-preview", "rust-src", "rust-std", "rustc", "rustc-dev", "rustfmt"]

• (This assumes you don't have that toolchain installed.)
• Edit the source file.
• ZZ

Expected vs. actual behavior:

I expected this to quickly save and exit. Instead, it hung with no visible output. I had to strace it to realize that it was running rustfmt --help, which was updating itself via rustup because of the rust-toolchain file.

Please don't run rustfmt --help unless actually running rustfmt.
