在Erlang中，何时使用;或，或。？ [英] In Erlang, when do I use ; or , or .?

问题描述

我一直在尝试学习Erlang，并且在函数和 case 语句的结尾行遇到了一些问题。

I have been trying to learn Erlang and have been running into some problems with ending lines in functions and case statements.

我何时在函数中使用分号（; ），逗号（，）或句点或 case 语句？

When do I use a semicolon (;), comma (,), or period inside my functions or case statements?

推荐答案

正常代码行末尾的逗号。 br>
case语句末尾或if语句等的分号。
最后一个case或if语句末尾没有任何内容。
函数末尾的句点。

Comma at the end of a line of normal code.
Semicolon at the end of case statement, or if statement, etc. The last case or if statement doesn't have anything at the end. A period at the end of a function.

示例（对不起，随机变量名称不起作用，显然它没有任何作用，但只说明了一点） ：

example (sorry for the random variable names, clearly this doesn't do anything, but illustrates a point):

case Something of 
    ok ->
        R = 1,     %% comma, end of a line inside a case 
        T = 2;     %% semi colon, end of a case, but not the end of the last
    error ->
        P = 1,     %% comma, end of a line inside a case
        M = 2      %% nothing, end of the last case
end.               %% period, assuming this is the end of the function, comma if not the end of the function
