This feature requires the user to add a command that generates a
`rust-project.json` from a set of files. Project discovery can be invoked
in two ways:
1. At extension activation time, which includes the generated
`rust-project.json` as part of the linkedProjects argument in
InitializeParams
2. Through a new command titled "Add current file to workspace", which
makes use of a new, rust-analyzer specific LSP request that adds
the workspace without erasing any existing workspaces.
I think that the command-running functionality _could_ merit being
placed into its own extension (and expose it via extension contribution
points), if only provide build-system idiomatic progress reporting and
status handling, but I haven't (yet) made an extension that does this.
VS Code problem matcher are restricted to be static "regexes". You can't
create a problem matcher dynamically, and you can't use custom code in
lieu of problem matcher.
This creates a problem for rust/cargo compiler errors. They use paths
relative to the root of the Cargo workspace, but VS Code doesn't
necessary know where that root is.
Luckily, there's a way out: our current problem matcher is defined like
this:
"fileLocation": [ "autoDetect", "${workspaceRoot}" ],
That means that relative pahts would be resoleved relative to workspace
root. VS Code allows to specify a command inside `${}`. So we can plug
custom logic there to fetch Cargo's workspace root!
And that's exactly what this PR is doing!
Inlay hints are no longer something specifc to r-a as it has been
upstreamed into the LSP, we don't have a reason to give the config
for this feature special treatment in regards to toggling. There are
plenty of other options out there in the VSCode marketplace to create
toggle commands/hotkeys for configurations in general which I believe
we should nudge people towards instead.
This PR will fix some typos detected by [typos].
There are also some other typos in the function names, variable names, and file
names, which I leave as they are. I'm more certain that typos in comments
should be fixed.

While VSCode [uses it's own implementation for URIs](https://github.com/microsoft/vscode-uri)
which notably doesn't have any limits of URI size, the renderer itself
relies on Web platform engine, that limits the length of the URLs and
bails out when the attribute length of an `href` inside `a` tag is too
long.
Command URIs have a form of `command:command-name?arguments`, where
`arguments` is a percent-encoded array of data we want to pass along to
the command function. For "Show References" this is a list of all file
URIs with locations of every reference, and it can get quite long.
This PR introduces another intermediary `linkToCommand` command. When
we render a command link, a reference to a command with all its arguments
is stored in a map, and instead a `linkToCommand` link is rendered
with the key to that map.
For now the map is cleaned up periodically (I've set it to every
10 minutes). In general case we'll probably need to introduce TTLs or
flags to denote ephemeral links (like these in hover popups) and
persistent links and clean those separately. But for now simply keeping
the last few links in the map should be good enough. Likewise, we could
add code to remove a target command from the map after the link is
clicked, but assuming most links in hover sheets won't be clicked anyway
this code won't change the overall memory use much.
Closes#9926
