* allow rustfmt to reorder importsAleksey Kladov2019-07-04166-788/+772
| | | | | | This wasn't a right decision in the first place, the feature flag was broken in the last rustfmt release, and syntax highlighting of imports is more important anyway

| * | Support attributes on array membersRyan Cumming2019-06-307-0/+205
| |/ | | | | | | | | | | | | | | | | | | | | | | Array members are allow to have attributes such as `#[cfg]`. This is a bit tricky as we don't know if the first expression is an initializer or a member until we encounter a `;`. This reuses a trick from `stmt` where we remember if we saw an attribute and then raise an error if the first expression ends up being an initializer. This isn't perfect as the error isn't correctly located on the attribute or initializer; it ends up immediately after the `;`.

For example, with E0061: ```json { "message": "this function takes 2 parameters but 3 parameters were supplied", "spans": [{"label": "expected 2 parameters"}] } ``` However, with some mismatched type errors (E0308) the expected type only appears in the primary span's label, e.g.: ```json { "message": "mismatched types", "spans": [{"label": "expected usize, found u32"}] } ``` I initially added the primary span label to the message unconditionally. However, for most error types the child diagnostics repeat the primary span label with more detail. `rustc` also renders the duplicate text but because the span label and child diagnostics appear in visually distinct places it's not as confusing. This takes a heuristic approach where it will only add the primary span label if there are no child message lines. For most error types the child messages repeat the primary span label with more detail. Co-authored-by: Ryan Cumming <[email protected]>

|\ \ | |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | 1454: Fix `cargo watch` code action filtering r=etaoins a=etaoins There are two issues with the implementation of `provideCodeActions` introduced in #1439: 1. We're returning the code action based on the file its diagnostic is in; not the file the suggested fix is in. I'm not sure how often fixes are suggested cross-file but it's something we should handle. 2. We're not filtering code actions based on the passed range. The means if there is any suggestion in a file we'll show an action for every line of the file. I naively thought that VS Code would filter for us but that was wrong. Unfortunately the VS Code `CodeAction` object is very complex - it can handle edits across multiple files, run commands, etc. This makes it complex to check them for equality or see if any of their edits intersects with a specified range. To make it easier to work with suggestions this introduces a `SuggestedFix` model object and a `SuggestFixCollection` code action provider. This is a layer between the raw Rust JSON and VS Code's `CodeAction`s. I was reluctant to introduce another layer of abstraction here but my attempt to work directly with VS Code's model objects was worse. Co-authored-by: Ryan Cumming <[email protected]>

However, if you have something like `cargo-watch.command` set to `clippy` it will also watch for Clippy lints. The `rustc` source is a bit misleading in that case. Fortunately, Rust's tool lints ([RFC 2103](https://github.com/rust-lang/rfcs/blob/master/text/2103-tool-attributes.md)) line up perfectly with VS Code's concept of `source`. This checks for lints scoped to a given tool and then splits them in to a `source` and tool-specific `code`. Co-authored-by: Ryan Cumming <[email protected]>

Make a change to Rust source code using all the analysis magic 2. Save the file to trigger `cargo watch`. I have format on save enabled for all file types so this also runs `rustfmt` 3. Fix any diagnostics that `cargo watch` finds Unfortunately if the Rust source has any syntax errors the act of saving will pop up a scary "command has failed" message and will switch to the "Output" tab to show the `rustfmt` error and exit code. I did a quick survey of what other Language Servers do in this case. Both the JSON and TypeScript servers will swallow the error and return success. This is consistent with how I remember my workflow in those languages. The syntax error will show up as a diagnostic so it should be clear why the file isn't formatting. I checked the `rustfmt` source code and while it does distinguish "parse errors" from "operational errors" internally they both result in exit status of 1. However, more catastrophic errors (missing `rustfmt`, SIGSEGV, etc) will return 127+ error codes which we can distinguish from a normal failure. This changes our handler to log an info message and feign success if `rustfmt` exits with status 1. Another option I considered was only swallowing the error if the formatting request came from format-on-save. However, the Language Server Protocol doesn't seem to distinguish those cases.
