摩天大楼是什么意思? [英] What does sky-scrapper mean?

问题描述

在这个 answer 中有一个带有注释的 Prolog 谓词

In this answer there is a Prolog predicate with the comment

% replace OR sky-scrapper with call to new predicate

我看到的前几页谷歌搜索没有结果来解释其含义.

Googling has no results for the first few pages that I see to explain its meaning.

评论中使用的sky-scrapper的含义和起源是什么?

What is the meaning and origin of sky-scrapper as used in the comment?

推荐答案

在链接中的示例代码中，OP使用了以下样式

In the example code in link, the OP has used below style

  (  ":",       !, { Token = tokColon }
  ;  "(",       !, { Token = tokLParen }
  ;  ")",       !, { Token = tokRParen }
  ;  "{",       !, { Token = tokLMusta}
  ;  "}",       !, { Token = tokRMusta}
  ;  "\\",      !, { Token = tokSlash}
  ;  "->",      !, { Token = tokImpl}
  ;  "+",       !, { Token = tokPlus }
  ;  "-",       !, { Token = tokMinus }
  ;  "*",       !, { Token = tokTimes }
  ;  "=",       !, { Token = tokEqual }
  ;  "<",       !, { Token = tokLt }
  ;  ">",       !, { Token = tokGt }
  ;  "_",       !, { Token = tokUnderscore }
  ;  ".",       !, { Token = tokPeriod }
  ;  "/",       !, { Token = tokForwardSlash }
  ;  ",",       !, { Token = tokComma }
  ;  ";",       !, { Token = tokSemicolon }

这个片段像摩天大楼一样长(高)，这就是恕我直言使用术语的原因

this snippet is long(tall) like sky scraper, and thats why terminology is used IMHO

所以建议OP替换它使用更合适的代码段，这主要是为了生成更多可读和可维护代码
