Google Go：尽管有关键字 [英] Google Go: notwithstanding keyword

问题描述

在Google Go中，尽管关键字的意思是什么？

解决方案

2017更新：有一个主要的解析器更新，新的似乎不再支持这些复活节彩蛋词语。

看起来像词法分析器中的复活节彩蛋：

https://github.com/golang/go/blob/08e25fc1ba397e02ec776561ed73b7f9a8b94392/src/cmd/compile /internal/gc/lex.go#L2152-L2156

相关部分是符号表：

 尽管，LIGNORE，Txxx，OXXX，
thetruthofthematter，LIGNORE，Txxx，OXXX，
尽管有反对意见，LIGNORE，Txxx，OXXX ，
而，LIGNORE，Txxx，OXXX，
insofaras，LIGNORE，Txxx， OXXX，
  

我猜他们可以用来测试词法类型LIGNORE的处理，但是没有' t似乎是任何真正的被忽略的令牌。

What does the notwithstanding keyword mean in Google Go?

解决方案

2017 Update: There was a major parser update and the new one no longer seems to support these Easter egg words.

Looks like an easter egg in the lexer to me:

https://github.com/golang/go/blob/08e25fc1ba397e02ec776561ed73b7f9a8b94392/src/cmd/compile/internal/gc/lex.go#L2152-L2156

the relevant section is the symbol table:

"notwithstanding",      LIGNORE,    Txxx,       OXXX,
"thetruthofthematter",  LIGNORE,    Txxx,       OXXX,
"despiteallobjections", LIGNORE,    Txxx,       OXXX,
"whereas",              LIGNORE,    Txxx,       OXXX,
"insofaras",            LIGNORE,    Txxx,       OXXX,

I guess they could be used to test handling of the lexical type LIGNORE, but there doesn't seem to be any "real" ignored tokens.
