可惜的是,Go 不会把 errors 作为 boolean 表达式处理,也不允许在 boolean 表达式中赋值,会提示错误 ”expected boolean expression, found simple statement (missing parentheses around composite literal?)“ 。对于这一点我并不是很强烈的认为不好,因为还有其他的方法可以做到。如果你在其他语言例如 Node 或者 PHP,...
对于匹配的子串,FindIndex() 和 FindStringIndex() 返回的是一个长度为 2 的 int 数组,loc[0] 是子串的起始索引,loc[1] 是子串结束索引的下一位,注意这里是左闭右开 [loc[0], loc[1]) ,索引从 0 开始,。FindAllIndex() 和 FindAllStringIndex() 也差不多,返回的是一个二维的 int 数组,同样存的...

With the(?i)syntax, the regular expression is case insensitive. The(es)?indicates that "es" characters might be included zero times or once. found := re.FindAllString(content, -1) We look for all occurrences of the defined regular expression withFindAllString. The second parameter is the...
This expression does not make sense in mathematics, but it is legal in programming. The expression adds 1 to thexvariable. The right side is equal to 2 and 2 is assigned tox. 3 = x This code line leads to a syntax error. We cannot assign a value to a literal. ...
While all queries on the cloc documentation should work as expected, you will not be able to append output fromsccandclocinto the same database. This is because the table format is slightly different to account for scc including complexity counts and bytes. ...
