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.
fix: Suppress extra indent after the end of field and function chains
(spurred on by <https://github.com/rust-lang/rust-analyzer/issues/4182#issuecomment-671275652>)
Caveat that this doesn't work for after tail expressions, although there shouldn't be anything after those anyways.
This also complicates when to reload the language configuration by nature of now always having a language configuration applicable.
Examples of indentation fixes:
```rs
fn main() {
println!("Hello!"); // < enter here!
// ... indents down here
fs::read_to_string("soup") // < enter here!
// ... still indents down here :(
.map(|_| ())
.map(|_| ()) // < enter here!
// ... still indents down here :D
.map_err(|_| ())
.unwrap(); // < enter here!
// ... indents down here :D
// ... and subsequent enters stay at the same indent
0.0f64
.to_radians()
.to_radians()
.to_radians() // force semi on a new line
; // < enter here!
// ... indents down here :D
}
fn tail_end() -> i32 {
0i32.wrapping_abs()
.wrapping_abs()
.wrapping_abs()
.wrapping_abs() // < enter here!
// ... still indents here 🤷
}
```
Use ANSI control characters to display text decorations matching the
VScode terminal theme, and strip them out when providing text content
for rustc diagnostics.
This adds the small `anser` library to parse the control codes, and it
also supports HTML output so it should be fairly easy to switch to a
rendered HTML/webview implementation if desired.
