Swift Plugin for the Opinionated Code Formatter
What does it do?
⚠️ Warning ⚠️ This plugin might eat your homework in its early stage. It also depends on Swift's lib/Syntax which is in flux. Please stage or commit your code before performing any in-place formatting.
You can check out how it formatted Artsy's Eidolon.
Prerequisites
You need one of the following:
- A snapshot from March 30, 2018 or later,
- a recent manual build from Swift's
master
, or - Swift 4.2 (once it's available as a beta or released completely).
Assuming you picked (1) please follow the
installation instructions,
which recommend updating your PATH
at the end:
TOOLCHAIN=swift-DEVELOPMENT-SNAPSHOT-2018-03-30-a.xctoolchain
export PATH=/Library/Developer/Toolchains/${TOOLCHAIN}/usr/bin/:"${PATH}"
Alternatively you can pass the full path to the swiftc
binary
via the environment variable PRETTIER_SWIFT_SWIFTC
:
TOOLCHAIN=swift-DEVELOPMENT-SNAPSHOT-2018-03-30-a.xctoolchain
export PRETTIER_SWIFT_SWIFTC=/Library/Developer/Toolchains/${TOOLCHAIN}/usr/bin/swiftc
