Based on my different pieces of feedback, here is a rough sketch of how I think this should behave if cmd.starts_with('+') {
anyhow::format_err!("no such subcommand: `{}`{}\n\n\tCargo does not handle `+toolchain` directives itself.\n\tDid you mean to run `cargo` through `rustup` instead?", cmd, did_you_mean)
} else {
let suggestions = list_commands(config);
let did_you_mean = closest_msg(cmd, suggestions.keys(), |c| c);
anyhow::format_err!("no such subcommand: `{}`{}\nView all installed commands with `cargo --list`", cmd, did_you_mean)
} |
There was a problem hiding this comment.
There are a few places where this update is not being checked. It might be good to update a few of the tests from with_stderr_contains to use with_stderr i.e.
.with_stderr(
"\
error: no such subcommand: `C`
<tab>Did you mean `c`?
<tab>View all installed commands with `cargo --list`
",
)@epage do you have any thoughts on this?
