clippy-dirty

cargo clippy, but only for files / lines you've just modified.

Abstract

By default, cargo clippy shows messages for the entire project - that is: even if you modified a single file, you'll still see all the messages for all of the other files in your crate.

This is a great behavior overall, but can be troublesome when you start to introduce clippy to your workflow and can't afford to apply all the suggestions at once.

And for that comes clippy-dirty - it's a script that, simplifying a bit, invokes git status and cargo clippy, and shows only those messages that affect uncommitted files.

It can even narrow down messages to just the lines you've modified - you'll find the synopsis below.

Installation

• clone this repository and add it to your PATH
• (or) download the clippy-dirty script wherever you like and invoke it using full path (e.g. ~/Apps/clippy-dirty)

Usage

Use in place of cargo clippy, e.g.:

$ cd ~/Projects/go-brr-meme-maker
$ clippy-dirty
# or
$ clippy-dirty -- -p workspace-crate
# and so on

USAGE
    clippy-dirty [options] [--] [clippy-options]

OPTIONS
    -b files  Shows messages only for the files you've modified
              (this is the default behavior)

    -b lines  Shows messages only for the lines you've modified
              (it's more restrictive than '-b files')

    -u        Ignore untracked files

    -h        Prints this help

Arguments after '--' get passed into clippy:
    clippy-dirty -- -p workspace-crate
    clippy-dirty -- --all-targets --all-features
    clippy-dirty -- -- -D clippy::new_without_default
    clippy-dirty -b lines -- -- -D clippy::new_without_default

Same for environmental variables:
    RUSTFLAGS="-D warnings" clippy-dirty
