So, some context for this, well, more a story. I'm not used to scripting, I've never really scripted anything, even if it's a valuable skill. I just never really needed it. Now, `@flip1995` correctly suggested using a script for this in `rust-clippy#7813`...
And I decided to write a script using nushell because why not? This was a mistake... I spend way more time on this than I would like to admit. It has definitely been more than 4 hours. It shouldn't take that long, but me being new to scripting and nushell just wasn't a good mixture... Anyway, here is the script that creates another script which adds the versions. Fun...
Just execute this on the `gh-pages` branch and the resulting `replacer.sh` in `clippy_lints` and it should all work.
```nu
mv v0.0.212 rust-1.00.0;
mv beta rust-1.57.0;
mv master rust-1.58.0;
let paths = (open ./rust-1.58.0/lints.json | select id id_span | flatten | select id path);
let versions = (
ls | where name =~ "rust-" | select name | format {name}/lints.json |
each { open $it | select id | insert version $it | str substring "5,11" version} |
group-by id | rotate counter-clockwise id version |
update version {get version | first 1} | flatten | select id version);
$paths | each { |row|
let version = ($versions | where id == ($row.id) | format {version})
let idu = ($row.id | str upcase)
$"sed -i '0,/($idu),/{s/pub ($idu),/#[clippy::version = "($version)"]\n pub ($idu),/}' ($row.path)"
} | str collect ";" | str find-replace --all '1.00.0' 'pre 1.29.0' | save "replacer.sh";
```
And this still has some problems, but at this point I just want to be done -.-

/// ### What it does
|
|
/// Checks to see if multiple versions of a crate are being
|
|
/// used.
|
|
///
|
|
/// ### Why is this bad?
|
|
/// This bloats the size of targets, and can lead to
|
|
/// confusing error messages when structs or traits are used interchangeably
|
|
/// between different versions of a crate.
|
|
///
|
|
/// ### Known problems
|
|
/// Because this can be caused purely by the dependencies
|
|
/// themselves, it's not always possible to fix this issue.
|
|
///
|
|
/// ### Example
|
|
/// ```toml
|
|
/// # This will pull in both winapi v0.3.x and v0.2.x, triggering a warning.
|
|
/// [dependencies]
|
|
/// ctrlc = "=3.1.0"
|
|
/// ansi_term = "=0.11.0"
|
|
/// ```
