中文导读
Go 语言联合创始人 Rob Pike 在 2011 年悉尼 Google 技术用户组上的分享。他用状态函数、goroutine 和 channel 优雅重构了 Go text/template 的词法分析器(lexer),展现了地道的 Go 并发哲学。
为什么 HN 推它
HN 常青树级演讲。即使你没有任何编译器和词法分析背景,也能顺畅领略这套词法解析方案的极简与优雅。
「听起来枯燥,看进去却极有意思;哪怕你完全不懂语法解析,也完全能跟上作者的思路。」HN 网友原话:It's far more interesting than it sounds, and even if you don't know much about lexing/parsing it's easy to follow.
英文原摘要(HackerTube / Claude 整理)
Rob Pike shows how the Go text/template lexer is built, using state functions, goroutines and channels. The talk was given at a Google Technology User Group in Sydney in 2011.
HN returns to it for years as an elegant introduction to writing a lexer that is easy to follow even without a parsing background.
HN 上的提及
watching Pike's talk on lexing and parsing in Go really hits this point home.
Rob Pike has an excellent video about this
There's a video by Pike describing how he built the parser at
same as in Lexical Scanning in Go
