question - how to get stdlib sources for intellij?

[timabell]

Hi, this is more of a question than a bug, I hope you don't mind me asking here.

I have installed rustc etc with this asdf plugin and that's all working great.

When I open the project I'm working on in IntelliJ (CLion) with the IntelliJ Rust plugin it can't find stdlib and asks for the location or rustup. Having looked around it seems this plugin only installs the tool binaries (which makes sense), so I don't currently have the sources it's looking for.

I haven't installed rustup as presumably that overlaps in purpose with asdf. I don't really want to mess up my asdf setup by using rustup so I'm not sure what to do.

Edit I got this working as per https://stackoverflow.com/questions/41464063/how-to-provide-standard-library-sources-for-intellij-ideas-rust-project/63934669#63934669 by downloading and extracting the sources directly from the source code links at the bottom of https://forge.rust-lang.org/infra/other-installation-methods.html#source-code and telling IntelliJ where to find them:

I guess ideally it'd be cool if this asdf plugin could also pull in the sources needed for intellij to behave.

I'm actually facing a similar issue and found this issue through some Googling. My VSCode and Vim setups can't autocomplete std modules. My own code in the workspace autocompletes just fine.

I've tried updating the $RUST_SRC_PATH env var to point to asdf's current toolchain and the included std lib source, but this hasn't had an effect. Not quite sure how to debug this further at the moment. I suspect the editors are just not picking up the asdf toolchain or something?

This might not even really be an issue with asdf itself, but would love to hear if/how someone else has resolved this.

Ended up solving my issue, I think. Seems like rustup is setting the path for $RUST_SRC_PATH incorrectly. Nothing to do with asdf.

After I updated it from

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

to (note the last part)

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

things started working for me.

I just ran into this, I don't even see src in my install:

❯ find /Users/sontek/.asdf/installs/rust/1.61.0 -name src
/Users/sontek/.asdf/installs/rust/1.61.0/share/doc/rust/html/book/2018-edition/src

Same as @sontek , I don't have a src dir in my asdf installed rustc --print sysroot.

This causes my VS Code extension rust-analyzer to spit out errors.

[arturictus]

Same as @sontek and @cjbottaro , No src in the installation. My VS Code extension rust-analyzer is not working either.

[cjbottaro]

I switched to https://github.com/code-lever/asdf-rust and it works perfectly.

Which is frustrating because "asdf-community" sounds more official.

Something like this should work and put it in the same location as rustup:

pushd $(rustc --print sysroot)
mkdir -p lib/rustlib/src
wget https://github.com/rust-lang/rust/archive/refs/tags/$(basename $(pwd)).tar.gz -O lib/rustlib/src/archive.tar.gz
cd lib/rustlib/src
tar vxzf archive.tar.gz
rm -f archive.tar.gz
mv rust-* rust
popd

We should add this as a default or at the very lease a command for the plugin.

After install, just add the component using rust-up.

rustup component add rust-src

now the source will be present in the toolchain.
