From e0491f5466f79ce56cd010f5970a783c34756480 Mon Sep 17 00:00:00 2001 From: Jessica Tarra Date: Tue, 12 Mar 2024 17:40:43 -0300 Subject: [PATCH] feat: format built in command (#657) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This PR introduces a new built-in command called "format" that follows the same implementation logic used in the development of the "analyze" command, which was merged in a previous (PR). The purpose of this change is to eliminate the need to set up a separate script in order to format each package. For example, instead of using the following YAML configuration: scripts: format: description: Format Dart code. run: dart format . format:check: description: Check formatting of Dart code. run: dart format --output none --set-exit-if-changed . The first script can now be replaced with a simpler command: melos format. Similarly, the second script can be replaced with melos format --output none --set-exit-if-changed. Additionally, this new command supports all melos filtering options and concurrency. --- .github/workflows/validate.yaml | 2 +- docs/commands/format.mdx | 72 +++++ melos.yaml | 8 - packages/melos/README.md | 1 + packages/melos/lib/src/command_runner.dart | 2 + .../melos/lib/src/command_runner/format.dart | 63 +++++ packages/melos/lib/src/commands/format.dart | 130 +++++++++ packages/melos/lib/src/commands/runner.dart | 4 +- packages/melos/test/commands/format_test.dart | 267 ++++++++++++++++++ 9 files changed, 539 insertions(+), 10 deletions(-) create mode 100644 docs/commands/format.mdx create mode 100644 packages/melos/lib/src/command_runner/format.dart create mode 100644 packages/melos/lib/src/commands/format.dart create mode 100644 packages/melos/test/commands/format_test.dart diff --git a/.github/workflows/validate.yaml b/.github/workflows/validate.yaml index 44bc533e4..6ff61f6ba 100644 --- a/.github/workflows/validate.yaml +++ b/.github/workflows/validate.yaml @@ -62,7 +62,7 @@ jobs: - name: Install Tools run: ./.github/workflows/scripts/install-tools.sh - name: Check formatting - run: melos format:check + run: melos format --output none --set-exit-if-changed test_linux: runs-on: ubuntu-latest diff --git a/docs/commands/format.mdx b/docs/commands/format.mdx new file mode 100644 index 000000000..8c894cc24 --- /dev/null +++ b/docs/commands/format.mdx @@ -0,0 +1,72 @@ +--- +title: Format Command +description: Learn more about the `format` command in Melos. +--- + +# Format Command + +Supports all [Melos filtering](/filters) flags. + +The format command is used to format the code in your Melos workspace according +to Dart's formatting standards. + +```bash +melos format +``` + + +To learn more, visit the [Dart format](https://dart.dev/tools/dart-format) +documentation. + + + +## --set-exit-if-changed +Return exit code 1 if there are any formatting changes.
