Beschreibung
There is already an --emit json option that emits formatting changes as JSON. However if Rustfmt encounters a parse error it prints the error to stderr in human readable form and exits with error code 1.
$ rustfmt --emit json lib.rs
error: expected one of `!` or `::`, found `<eof>`
--> /.../src/lib.rs:16:1

| ^^^ expected one of `!` or `::`
failed to parse Real("/.../src/lib.rs")
It would be helpful in some situations to be able to have these errors in JSON format too. For example for IDE integration or CI. (One of my coworkers is using a horrible regex to parse this, against my advice!)
I think an --emit-errors json option would be reasonable.
- rustfmt version:
rustfmt 2.0.0-rc.2-nightly (e91edf56 2020-08-04) - From where did you install rustfmt?: Git
master, from yesterday.
