rustfmt-repl

A tiny adapter that lets rustfmt format Rust statement snippets used in Markdown code blocks and REPLs.

It first runs rustfmt on the input as a complete Rust source file. If that fails, it temporarily wraps the input in fn main(), formats it, and removes the wrapper again.

Build

cargo install rustfmt-repl

Usage

Read from stdin and write to stdout:

'let x=(1,2); dbg!(x,    x.0);' | rustfmt-repl

Or format a file in place:

rustfmt-repl path\to\snippet.rs

mdsf

{
  "languages": {
    "rust": {
      "binary": "C:\\Users\\dell\\.cargo\\bin\\rustfmt-repl.exe",
      "arguments": ["$PATH"],
      "stdin": false
    }
  }
}
