@btmills/prettier

:fork_and_knife: This is a fork.

Compared to prettier, @btmills/prettier moves binary operators to the beginning of new lines in long expressions instead of the end of the previous line. That's it.

// Before:
const before =
  bom.length >= 2 &&
  ((bom.charCodeAt(0) === 0xff && bom.charCodeAt(1) === 0xfe) ||
    (bom.charCodeAt(0) === 0xfe && bom.charCodeAt(1) === 0xff));

// After:
const after =
  bom.length >= 2
  && ((bom.charCodeAt(0) === 0xff && bom.charCodeAt(1) === 0xfe)
    || (bom.charCodeAt(0) === 0xfe && bom.charCodeAt(1) === 0xff));

Usage

If you use Yarn, you can install using an alias so that require('prettier') transparently resolves to this fork:

$ yarn add -D prettier@npm:@btmills/prettier

Releases

Releases of the forked package are done by rebasing the line-before-operator branch on top of the most recent version tag in master.

# Get the latest changes and update the master branch
$ git checkout master
$ git pull
$ git push fork
# Rebase the release branch on the latest version
$ git checkout line-before-operator
$ git rebase x.y.z
# Fix conflicts as necessary
$ git rebase --continue
# Update packages to give accurate test results
$ yarn install
# If any conflicts in snapshots, discard and update automatically
$ yarn test -u
# With rebasing done, run tests, push tags, build, and publish
$ yarn test
$ git tag x.y.z-fork
$ git push --force-with-lease --tags
$ yarn run build
$ yarn run test:dist
$ cd dist
$ npm publish

Intro

Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.

Input

foo(reallyLongArg(), omgSoManyParameters(), IShouldRefactorThis(), isThereSeriouslyAnotherOne());

Output

foo(
  reallyLongArg(),
  omgSoManyParameters(),
  IShouldRefactorThis(),
  isThereSeriouslyAnotherOne()
);

Prettier can be run in your editor on-save, in a pre-commit hook, or in CI environments to ensure your codebase has a consistent style without devs ever having to post a nit-picky comment on a code review ever again!

Changelog

1.16.2

diff

• CLI: Fix CI detection to avoid unwanted TTY behavior ([#5804] by [@kachkaev])

  In Prettier 1.16.0 and 1.16.1, --list-different and --check logged every file in some CI environments, instead of just unformatted files. This unwanted behavior is now fixed.

• HTML: Do not format non-normal whitespace as normal whitespace ([#5797] by [@ikatyang])

  Previously, only non-breaking whitespaces (U+00A0) are marked as non-normal whitespace, which means other non-normal whitespaces such as non-breaking narrow whitespaces (U+202F) could be formatted as normal whitespaces, which breaks the output. We now follow the spec to exclude all non-ASCII whitespace from whitespace normalization.

  (· represents a non-breaking narrow whitespace)

• JavaScript: Fix record type cast comment detection ([#5793] by [@yangsu])

  Previously, type cast comments with record types were ignored and prettier stripped the subsequent parens. Prettier 1.16.2 handles these cases correctly.
