⚠️ Stop saying "you forgot to …" in code review in Kotlin

Project status

The project is now on a stable version. Is possible to generate a working danger-kotlin instance from the code that is currently on this repo, or use it via GitHub actions or brew.

What it looks like today

You can make a Dangerfile.df.kts in your root project that looks through PR metadata, it's fully typed.

import systems.danger.kotlin.*

danger(args) {

    val allSourceFiles = git.modifiedFiles + git.createdFiles
    val changelogChanged = allSourceFiles.contains("CHANGELOG.md")
    val sourceChanges = allSourceFiles.firstOrNull { it.contains("src") }

    onGitHub {
        val isTrivial = pullRequest.title.contains("#trivial")

        // Changelog
        if (!isTrivial && !changelogChanged && sourceChanges != null) {
            warn(WordUtils.capitalize("any changes to library code should be reflected in the Changelog.\n\nPlease consider adding a note there and adhere to the [Changelog Guidelines](https://github.com/Moya/contributors/blob/master/Changelog%20Guidelines.md)."))
        }

        // Big PR Check
        if ((pullRequest.additions ?: 0) - (pullRequest.deletions ?: 0) > 300) {
            warn("Big PR, try to keep changes smaller if you can")
        }

        // Work in progress check
        if (pullRequest.title.contains("WIP", false)) {
            warn("PR is classed as Work in Progress")
        }
    }
}

Setup

macOS

brew install danger/tap/danger-kotlin

You need to have Xcode installed and not relying on command line tools. If you're seeing this error when running xcodebuild:

$ xcodebuild -version
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

You can fix it with:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

Linux

bash <(curl -s https://raw.githubusercontent.com/danger/kotlin/master/scripts/install.sh)
source ~/.bash_profile

      - name: Danger
        uses: danger/[email protected]
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Danger a pre built images that you can use with your action:

https://github.com/orgs/danger/packages/container/package/danger-kotlin In order to import one of those use the docker:// prefix

jobs:

        uses: docker://ghcr.io/danger/danger-kotlin:1.1.0
        with:
            args: --failOnErrors --no-publish-check
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Autocomplete and Syntax highlighting in IntelliJ IDEA or Android Studio

You can activate the autocomplete following this additional steps:

• Install danger on your local machine
• Go to Preferences -> Build, Execution, Deployment -> Compiler -> Kotlin Compiler (Preferences -> Kotlin Compiler in Android Studio)
• At the bottom you will find a section Kotlin Scripting
• Complete the field Script template classes with systems.danger.kts.DangerFileScript
• Complete the field Script templates classpath with /usr/local/lib/danger/danger-kotlin.jar
• Go to Preferences -> Language & Frameworks -> Kotlin -> Kotlin Scripting
• Make sure the script template DangerFileScript is active and above the default Kotlin Script
• Apply changes
• If opening the Dangerfile.df.kts the autocomplete and syntax highlighting doesn't work, try to reboot your IDE.

Using external maven dependencies into your Dangerfile

You can use any external dependency by adding the following lines at the top of your Dangerfile.df.kts

@file:Repository("https://repo.maven.apache.org")
@file:DependsOn("groupId:artifactId:version")

Commands

• danger-kotlin ci - Use this on CI
• danger-kotlin pr https://github.com/Moya/Harvey/pull/23 - Use this to build your Dangerfile
