add newline char to `cargo install .` error message for easier reading.
I just noticed the `cargo install .` error message was not formatted very nicely.
Just added a newline char to make it cleaner.
Thanks
Improve integration of the http server introduced by the http-registry feature.
Now the same HTTP server is used for serving downloads, the index, and
the API.
This makes it easier to write tests that deal with authentication and
http registries.
feat(install): Support `foo@version` like cargo-add
### What does this PR try to resolve?
This aims to make `cargo install` consistent with
- `cargo add foo@version` from #10472
- pkgid changes in #10582
- `cargo yank foo@version` from #10597
It also offers a shorthand for people installing a specific version.
### How should we test and review this PR?
#10582 acted as the FCP for this, see #10597
Documentation updates are split into their own commit to not clog up browsing the code.
Examine the tests to see if they make sense
### Additional information
While the `foo@vewrsion` syntax is the same, each's semantics are different. We had decided it was better to have the same syntax with different semantics than having the user worry about what syntax they use where. In `cargo install`s case, it has an
implicit-but-required `=` operand while `cargo-add` allows any operand.
This doesn't use the full `pkgid` syntax because that allows syntax that
is unsupported here.
This doesn't use `cargo-add`s parser because that is for version reqs.
I held off on reusing the parser from `cargo-yank` because they had
different type system needs and the level of duplication didn't seem
worth it (see Rule of Three).
In #10472, cargo-add was merged with support for an inline version
syntax of `foo@version`. That also served as the change proposal for
extending that syntax to `cargo install` for convinience and consistency.
While both commands are specifying a version-req, `cargo-install` has an
implicit-but-required `=` operand while `cargo-add` allows any operand.
This doesn't use the full `pkgid` syntax because that allows syntax that
is unsupported here.
This doesn't use `cargo-add`s parser because that is for version reqs.
I held off on reusing the parser from `cargo-yank` because they had
different type system needs and the level of duplication didn't seem
worth it (see Rule of Three).
During the design conversations on cargo-add, we noticed that
`cargo-install` has a public flag `--version` and an invisible alias
`--vers` while `cargo-yank` has a public flag `--vers`. This switches
`cargo-yank` to publicly use `--version` and have an invisible alias
`--vers`, making them consistent.
Completions are a best guess.
Inspired by #10345, I looked for other cases where
`toml_edit::easy::to_string` is used (which outputs inline tables) to
see if we should switch to `to_string_pretty`. The crates v1 file was
the only case I found.
As a side effect, we can no longer elide the empty `dev-dependencies`
table in published manifests. This was the behavior before `toml_edit`,
so not much of a loss.
Benefits:
- A TOML 1.0 compliant parser
- Unblock future work
- Have `cargo init` add the current crate to the workspace, rather
than error
- #5586: Upstream `cargo-add`
This works by introspecting rustc's error output, using the JSON format
to determine whether it's a warning or error, then skipping it
altogether if it's a summary of the diagnostics printed.
Before:
```
src/main.rs:1:10: warning: trait objects without an explicit `dyn` are deprecated
src/main.rs:1:1: error[E0601]: `main` function not found in crate `wrong`
src/main.rs:1:9: error[E0038]: the trait `Clone` cannot be made into an object
error: aborting due to 2 previous errors; 1 warning emitted
error: could not compile `wrong`
```
After:
```
$ cargo check --message-format short
src/main.rs:1:10: warning: trait objects without an explicit `dyn` are deprecated
src/main.rs:1:1: error[E0601]: `main` function not found in crate `wrong`
src/main.rs:1:9: error[E0038]: the trait `Clone` cannot be made into an object
error: could not compile `wrong` due to 2 previous errors; 1 warning emitted
```
If we're installing in --locked mode and there's no `Cargo.lock` published
ie. the bin was published before https://github.com/rust-lang/cargo/pull/7026
the cargo install errors were not stating that it was due to the lack of
the `Cargo.lock` file. Instead, the error seemed completely unrelated.
Therefore, this tries to address this by adding a warn in the stderr
output.
Closes#9106
Sweep unrelated message from unnecessary workspace infromation
Resolves#8619
Only pass workspace information when the source is from a local crate installation.
