[jkaye2012]

This is one of the biggest issues I have working with Rust from Emacs. Lack of completion for third-party libraries makes it much more painful to use many of them than it should be.

Can anyone provide a good starting point for how one could debug/fix this issue? It seems that the relevant code is somewhere in nameres.rs/cargo.rs (or the interaction between them), but I haven't found a good way to reliably test changes as I make them.

[jwilm]

Does this affect all third party crates, or just some? I've found the third party crate support to be good overall, but I haven't updated for a while, and it's possible there's been a regression.

[jkaye2012]

At least the redis crate and rust-zmq aren't working for me. Do you have an example of one that's working for you so I can test it out on my setup?

[jwilm]

The Redis crate suffers from a known infinite recursion bug in Racer. One crate that works for me is uuid. I can provide lots more examples if you like.

[jkaye2012]

Looks like that works for me as well! Seems like I've been getting unlucky to have the dependencies I've been using not work.

I guess this becomes more about finding the edge cases in external crate completion then - I would be more than willing to look into this if a current contributor could share with me how they go about testing and verifying their changes.

[sunchao]

I have the same issue: racer couldn't complete anything from cargo. Anyone know how to resolve this? Thanks.

[zhxchen17]

The same issue on Window 10, but racer seems to complete correctly under my Arch Linux environment.

[zoumi]

I have the same issue.
system: Window7 64bit
rust:Rust nightly GNU 1.10 32bit

[jwilm]

For those of you not on windows; are you using multirust? Support for multirust cargo packages was removed back in May. Switching to rustup.rs seems to fix the problem.

[DominoTree]

I had what appeared to be the same issue while I was using rustup.rs on OS X, but it's been a couple of weeks since I tried

[jwilm]

@DominoTree there's some other issues which may cause completions to fail, but this seemed like the biggest offender. I've got PRs up for the other issues I'm aware off (TOML parse failure -> panic, dropping a diagnostic builder)

[zoumi]

@jwilm
I didn't use multirust.I installed rust from the .mis intaller.

I'm using sublime text. Sometimes it works, and sometimes do not.But it never complete for crate user32-ays.
And it take much of time to complete for winapi crate.It makes me annoyed.
Can there be a cache to speed up it?

[DominoTree]

@jwilm - I've done a fresh OS install with rustup and built racer from the latest git source, and I'm still unable to complete anything that isn't either in the stdlib or in the current directory. I've pasted a bunch of stuff below - if there's anything else I can provide that would be helpful, please let me know.

@DominoTree can you run the complete command with RUST_LOG=racer=trace? This will be a firehose of data, so maybe you could provide it as a gist?

Super appreciate your debugging efforts.

Hmm, it seems that in Vim, working in a project that uses pcap - racer is able to complete pcap:: but when I call racer complete pcap:: from the command line, it gives me no results.

[JohnMurray]

So I've been having similar issues and this ticket (in various forms) seems to be repeated in this project's issues so sharing this find if not mentioned elsewhere or if someone finds this helpful. Just playing around for a bit, this seems to work (although it's a complete hack). I appended my source path with a direct path to iron (the crate I'm most interested in getting working) and now I'm seeing completions.

export RUST_SRC_PATH="${RUST_SRC_PATH}:$HOME/.cargo/registry/src/github.com-1ecc6299db9ec823/iron-0.4.0/src";

Sill having issues getting this to work within an editor (even with this path set), but still interesting.

[pronebird]

Can't make it work for third party modules either. Any diagnostics or anything we can gather to help solving this?

[jwilm]

Can't make it work for third party modules either. Any diagnostics or anything we can gather to help solving this?

More than having the right diagnostics, the real problem is time. There's not a lot of bandwidth among regular racer contributors to dig into our issue backlog. The time I personally have for Racer has been going towards support for RLS, and next on that list is fixing the stack overflow that can bring down the entire process. We would seriously welcome any help we can get, and I can make time to help land PRs (of which there is a minor backlog at the moment 😞).

To answer your question though, I think @DominoTree's comment about working in vim versus not working on the command line would be a good lead to chase down (what's different in these cases?). It seems like the reports here are about not working on the command-line. This matches what I've observed since Racer works fine when called from YCM.

[DominoTree]

I've rebuilt my entire environment a few times since I've posted here, but I just checked and on the latest Git version of racer, I am able to use it to complete the hyper crate in Vim, but not from the command-line.

I'm going to start hacking around and see if I can figure out what's going on, since it seems that I'm still able to replicate this behavior.

[jwilm]

Thanks @DominoTree! 😄

Looking forward to hear what you find out.

[DominoTree]

Just getting started, but at first glance, I think this behavior might be caused by do_file_search in namers.rs not looking at Cargo.lock in the current directory or project root.

It looks like all it does is check the environment var with let srcpaths = std::env::var("RUST_SRC_PATH").unwrap_or("".into());

Providing a file path, line number, and character number to racer on the command line provides proper completions for third-party crates.

I'll keep poking around and see if I can make it behave differently.

[DominoTree]

Got a chance to look at this some more and it does look like it's simply that attempting a completion as an argument to racer will not look for any external crates because not in the context of a project or a source file.

I think if this were documented more clearly, people wouldn't try to complete crates on the commandline and then assume that racer is broken.

We could also have racer try to find the nearest Cargo.toml file and use that, but I think that could introduce even more confusion.

I'm also wondering about what benefits there are from having this completion available in the first place, other than quickly testing whether racer works or not.

[jwilm]

@DominoTree thank you so much for continuing to look into this!

attempting a completion as an argument to racer will not look for any external crates because not in the context of a project or a source file.

We could also have racer try to find the nearest Cargo.toml file and use that, but I think that could introduce even more confusion.

I could imagine letting standard library completions work regardless, but for crate looks outside of a project, we should probably just detect that, print an error, and exit. Does that sound reasonable? Also, given your research, did you find that the command line completions work as expected in a project context?

I'm also wondering about what benefits there are from having this completion available in the first place, other than quickly testing whether racer works or not.

I don't quite understand this part. Are you suggesting the command line completion feature shouldn't exist other than checking that racer is hooked up properly? I think the way the stdio "daemon" mode works is to parse stdin lines as a set of arguments as if the program was run anew, so we can't exactly get rid of it. Even if that weren't true, I'm guessing at least a few people depend on the command line lookups since the feature was added at some point.

[bruno-medeiros]

As far as the second bit, I was mostly wondering aloud whether the complete option is really being used by anyone (seeing as it currently doesn't quite behave as expected)

Wait, what?

RustDT uses the complete command (well, complete-with-snippet actually). It doesn't use the daemon mode. I thought the daemon was just an optimization for start-up times, etc... are you saying completion works more accurately when in daemon mode?

[DominoTree]

Just tested, and, complete and complete-with-snippet on the commandline do not appear to look at Cargo.toml to find external crates to complete, as long as you're not providing a file name and line/char number to complete from. If you do provide them, it seems to work as expected.

In my earlier post, I think I'd made some incorrect assumptions about the complete commands.

I'm not really sure about daemon mode, or even potential differences from how racer may be called by RustDT. If RustDT is getting completions by file name and character position, it should work fine.

I'm trying to find some time to dig into this some more. Hopefully below illustrates what I'm trying to say.

Hey there, I came here because I have this problem on Windows 10 with racer 2.0.6. I appended %USERPROFILE%\.cargo\registry\src to RUST_SRC_PATH and with RUST_LOG=debug, I can see that racer is now searching in this directory as well. However, this doesn't give me code completion for external crates, including the aforementioned uuid. Is there any known fix for this? If no, what's the status?

[BigBeautifulBro]

I had an issue where racer did not work at all for nightly for crates from within emacs until I set an environment variable. Racer did work for me on stable in emacs without having to do anything special.

To fix the issue, I set the CARGO_HOME environment variable to something like C:\users\David\.cargo

I found the fix by googling for the issue and came across people with similar issues and solutions in this thread on reddit: https://www.reddit.com/r/rust/comments/50w0q2/racer_not_autocompleting_on_with_third_party/

I am using rustup.

my environment is as follows:
system: Windows 10 64bit
rust toolchain: nightly-x86_64-pc-windows-msvc

[theherk]

This issue persists. I'm on OSX and cannot complete from external crates. I can complete from rust-src.

export RUST_SRC_PATH=$(rustc --print sysroot)/lib/rustlib/src/rust/src
export CARGO_HOME=$HOME/.cargo

I'm unclear why CARGO_HOME is relevant since when running at debug I can see it only searched RUST_SRC_PATH.

[vlisivka]

I have same issue. Environment: Linux, Fedora 27.
I created simple project with just one external crate (see in attachment) and tried to get completion for it. Output:

@vlisivka
Is Cargo.lock generated?

[vlisivka]

@kngwyu Yes, Cargo.lock is generated. I built test project first, then added use nanomsg:: ; to test completion. I checked with strace -e trace=file, and racer does not try to open Cargo.* files.

@vlisivka
How about racer find-definition ?
I'm trying to reproduce, but now installing nanomsg package:sweat: in my distro

[vlisivka]

Sorry, I made few mistakes. It looks that racer need to be executed in top directory, not in src. Package versions in Cargo.toml must be exact, not "^0.6" or "*", because racer uses versions from Cargo.toml instead of Cargo.lock.

But still no luck with completion.

[vlisivka]

No luck with find-definition (racer 2.0.12):

I could reproduce, but, now I have no idea why racer can't find this crate and it needs more debugging 😨
Sorry very much, and, thanks for reporting!

I'm working with VS Code and Rust (rls) addon.

[Bravo555]

Command line returns nothing, but strangely enough, some completions work directly in the IDE:


Any ideas why and how could I show racer debug log in VS Code?

[vlisivka]

@Bravo555 Try to complete position in file, e.g. racer complete 2 13 src/main.rs

I think I am running to this issue on Windows 10. I installed the rand crate while going through "the book", but I can't seem to get any completions for it.

Completion on something such as std:: does work properly. Please let me know if there is anything I could do to help debug this further.

[kngwyu]

For nanomsg crate this problem is fixed in my branch.

[sashaweiss]

I'm still having issues with this - should the merged PR reference above have fixed the issue, slash has that PR been released?

My configurations are as below:

>>> cargo --version
cargo 0.26.0 (41480f5cc 2018-02-26)
>>> racer --version
racer 2.0.13
>>> rustc --version
rustc 1.25.0 (84203cac6 2018-03-25)
>>> echo $RUST_SRC_PATH
/Users/sasha/.rustup/toolchains/stable-x86_64-apple-darwin/lib/rustlib/src/rust/src
>>> echo $CARGO_HOME
/Users/sasha/.cargo
>>> racer complete termion::
>>> racer complete std::io::
<lots of stuff, removed for clarity>

If there's anything I can do to help debug further, please let me know! (Or if I'm doing something wrong - relatively new Rust user here.)

[kngwyu]

@sashaweiss
To complete names in outer crate, you have to run racer in cargo project.
Though my patch for nightly version solves many problem, I think stable(released) version of racer can complete names from termion crate.

[sashaweiss]

Thanks for the reply - I played around a bit more, and I've found that it sometimes completes and sometimes doesn't, and I'm having trouble identifying a pattern. Once I have more details to share I can follow up! Thanks again.

cargo 1.35.0-nightly (6f3e9c367 2019-04-04)
racer 2.1.22

vimrc

let g:ycm_rust_src_path = '/home/xxx/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src'

Racer can complete std but not any external crate like redis, geo etc

I still have this issue when running racer from the project folder with cargo.lock. It doesn't complete any external crates.
