Script to generate data shown in post 'At what time of day does famous programmers work? Part 2. Workweek vs Weekend.' — https://ivan.bessarabov.com/blog/famous-programmers-work-time-part-2-workweek-vs-weekend
Raw
script.go
/*
# Overview
git log --author="$GIT_USER_NAME" --format="%H %ai" の結果を集計するプログラムです。
# Usage
$ gcw --help
Usage of ./gcw:
-dir string
Path of git repository (default ".")
-tz string
Local Timezone (default "Asia/Tokyo")
-user string
Git username
$ gcw -user Gitユーザ名 -dir リポジトリのパス -tz ローカルタイムゾーン(デフォルトはAsia/Tokyo)
# Memo
このプログラムは、以下のブログ記事で利用されていたPerlスクリプトをGoに移植したものです。
元のスクリプトは
$ git log --author="$GIT_USER_NAME" --format="%H %ai" | perl script.pl
とパイプ経由で入力を受け取り、処理するようになっていましたが、Windows環境でも実行しやすいように
処理内で git コマンドも実行するように変更しています。
