永久機関が完成しちまったな～！
GitHub Actionsで毎晩fastlaneを走らせて、VersionをBump upしてPR作成して auto merge！永久機関が完成しちまったな～！これでノーベル賞は俺んもんだぜ～！
Version
今回はAndroidで行っていくぜ～
Semantic Versioningを参考にするぜ～
build.gradle.kts
// MAJOR * 100000 + MINOR * 10000 + PATCH * 1000
versionCode = 123000
versionName = "1.2.3"
今回はversionCodeを毎晩 Bump up させていくぜ～
fastlane
fastlane-plugin-versioning_androidを使用していくぜ～
fastlane
Fastfile
platform :android do
desc "Bump up version code"
lane :bump_up_version_code do
sh "git switch main"
previous_version_code = android_get_version_code(
gradle_file: "app/build.gradle.kts"
).to_i
version_name = android_get_version_name(
gradle_file: "app/build.gradle.kts"
)
version = version_name.split(".")
major_version = version[0].to_i * 100000
minor_version = version[1].to_i * 10000
patch_version = version[2].to_i * 1000
current_version = major_version + minor_version + patch_version
pre_release_version = previous_version_code - current_version
add_git_tag(
tag: "v#{version_name}-#{pre_release_version}",
)
push_git_tags
new_version_code = android_set_version_code(
gradle_file: "app/build.gradle.kts"
).to_i
new_pre_release_version = new_version_code - current_version
branch = "#{version_name}-#{new_pre_release_version}"
sh "git switch -c night-bump/#{branch}"
git_commit(
path: ["app/build.gradle.kts"],
message: ":up: Version Bump #{branch}"
)
push_to_git_remote(
set_upstream: true
)
end
end
bump upする前にgit tagをpushするぜえ～
tagはv1.2.3-0をpush、versionCode = 123001になるぜ～
GitHub Actions
workflowを作っていくぜ～

- fastlaneを実行させてPRを作るぜ～
- PR は auto merge しちゃうぜ～
- bump upする前のtagのReleasesを作成するぜ～
- 自動生成リリース ノートによっていい感じになるぜ～
RepositoryのPermission設定が重要だぜ～
これで永久機関が完成しちまったぜ～
止めない限り終わらないぜ～
GitHub Actionsは有能だな
