21. © - BASE, Inc. 概要 • Go⾔語開発の考え⽅ • Experiment/Simplify/Ship • Go • Error Handling • Generics • Dependencies Management • Go tools
22. © - BASE, Inc. Go初期の開発ループ • 2つのステージ • experimentから学び、 simplifyする https://blog.golang.org/experiment
23. © - BASE, Inc. Simplifyのための4つのR .Reshaping .Redefining .Removing .Restricting
24. © - BASE, Inc. Rs Reshaping 再形成 Redefine 再定義 https://blog.golang.org/experiment Removing 削除 Restricting 制約 • 有⽤性 or 重要性が低いものを 削除 • ソースファイル UTF- • gofmt
25. © - BASE, Inc. Go開発ループ • Ship（Goコードの出 荷）の追加 • ユーザーが試せるよう に https://blog.golang.org/experiment
26. © - BASE, Inc. Go • Error Handling • Generics • Dependencies Management • Go tools
27. © - BASE, Inc. Error Value History - 2008年 syscall errorはint型で定義 - `errno int ` - 2008年 ↑の2時間後error typeが⽣まれる - type Error struct、Print()‧String()という２つのシグネ チャを持っていた - 2009年 Error interface - Print()が取り除かれ現在の形へ - pkg/errorsなどError experimentsが⾊々 - experimentの結果が溜まってくる
28. © - BASE, Inc. Go Error Handling • Error Value Handling • Unwrap interface • errors.Is • errors.As • Error syntax • check? try? (abandoned)
29. © - BASE, Inc. Unwrap interface https://blog.golang.org/experiment • Optional なinterface • くるんだcontext內部のエラーを返す
