Golang Error Handling lesson by Rob Pike - Block Rockin’ Codes
Intro この記事は Go Advent Calendar 2014 の 15 日目の記事です。 例えばネットワークのフレーム処理的なものを書いている場合、以下のようなコードがよくでてきます。 There are many codes like this, while writing a Network Frame Parser program. var type uint8 err = binary.Read(r, binary.BigEndian, &type) if err != nil { return err } var length uint32 err = binary.Read(r, binary.BigEndian, &length) if err != nil { return err } ... 関数の中では、各要素の長さ毎に読み込んで、読み込みに失敗したらエラーを
Less is exponentially more
Here is the text of the talk I gave at the Go SF meeting in June, 2012. This is a personal talk. I do not speak for anyone else on the Go team here, although I want to acknowledge right up front that the team is what made and continues to make Go happen. I'd also like to thank the Go SF organizers for giving me the opportunity to talk to you. I was asked a few weeks ago, "What was the biggest surp
Self-referential functions and the design of options
I've been trying on and off to find a nice way to deal with setting options in a Go package I am writing. Options on a type, that is. The package is intricate and there will probably end up being dozens of options.

Rob Pike's simple C regex matcher in Go
Rob Pike’s simple C regex matcher in Go August 2022 Back in 1998, Rob Pike – of Go and Plan 9 fame – wrote a simple regular expression matcher in C for The Practice of Programming, a book he wrote with fellow Unix hacker Brian Kernighan. If you haven’t read Kernighan’s “exegesis” of this code, it’s definitely worth the 30-minute time investment it takes to go through that slowly. With Go’s C herit
