Thanks. Are you sure those are the same thing? The Rust toolchain also includes rust-analyzer, but it's usually pretty outdated. I would expect |
|
Thanks Inicola. First of all, please accept my apologies - I was not familiar with the fact that the version of rust-analyzer distributed with rust is older. I am working on setting up the helix editor and it needs rust-analyzer, but the original instructions failed to provide it, hence my pull request. I can't find reference to dev-util/rust-analyzer-bin in the standard gentoo portage repository, or in the guru repository. Do you know if it is available in a different overlay? |
|
The reference is in the paragraph you've deleted, I don't know if it still works. |
|
The guru overlay referenced in the original paragraph no longer includes dev-util/rust-analyzer - looking at this comment on their git repo, it was removed when the rust-analyzer flag was implemented on the dev-lang/rust and dev-lang/rust-bin packages: here I installed the overlay to confirm that it is indeed no longer present. In the absence of a better solution, the instructions in my pull request will at least give gentoo users a working version of rust-analyzer, albeit an older version. The version reported by rust-analyzer is currently is 1.71.1, aligned with the rust compiler. The date on the rust compiler release is 2023-08-03, so I guess the rust-analyzer version comes from around the same period. |
rust-analyzer gets synced with downstream once a week, but changes don't get ported to the beta branch. So for example, 1.77 will be released on March 21, gets branched on February 2, so only includes a RA version before that date, which is around January 29. And that's in the ideal case. At time syncs were suspended for months at a time, usually because of technical issues. |

Whats the status of this PR (I haven no clue about gentoo) |
|
If you use rust in Gentoo with the system installed tools, following the instructions in my pull request will ensure you have the version of rust-analyzer installed which came with the compiler release. The alternative is to use rustup at a user level, and install rust-analyzer that way - something I didn't document in the pull request. The instructions to use the guru overlay are not valid at present, since rust-analyzer has been removed as a package from that overlay. I recommend merging the pull request, and if you want me to document the rustup approach as well, then let me know and I will make another pull request to implement. |
|
If the guru version was removed than this seems to be better indeed already, adding rustup wouldn't hurt either here though but it doesn't matter too much. |

☀️ Test successful - checks-actions |

@paul-jewell did you end up asking the guru maintainers about this? I'll file a follow-up PR with my proposed addition in #15922 (comment). |
Tweak Gentoo instructions CC #15922 (comment)
No need to install the guru overlay to install rust-analyzer. This is now installed based on use flag settings for dev-lang/rust and dev-lang/rust-bin. This pull request changes the instructions in the user manual.
Note: rust-analyzer is not available in the guru repository, so the old instructions no longer work.
