sassylang 0.0.3

时髦

一种简单但功能强大的文本插值模板语言，灵感来自SAS宏。

工作原理

sassy是一个解释输入宏标记的命令行程序。

宏

%let var1 = some value;
%let var2 = some other value;

%macro testMacro(param1);
    this text will show whenever the macro is called.
    variables can be referenced like this: &var1.
    we can reference macro parameters just like variables: &param1.
%mend;

here's how you call a macro:
%exec testMacro(1);

here's a call to the same macro with a different parameter:
%exec testMacro(2);

在上述文本文件上运行sassy将输出以下内容…

$ sassy test.txt

    this text will show whenever the macro is called.
    variables can be referenced like this: somevalue
    we can reference macro parameters just like variables: 1

here's a call to the same macro with a different parameter:
    this text will show whenever the macro is called.
    variables can be referenced like this: somevalue
    we can reference macro parameters just like variables: 2

嵌套变量解析

%let var1 = some value;
%let var2 = some other value;
%let varNum = 1;

%macro testMacro(param1);
    variables can be nested to form references to other variables: &var&varNum..
    ...and also nest parameters as with variables: &var&param1..
%mend;

here's how you call a macro:
%exec testMacro(1);

here's a call to the same macro with a different parameter:
%exec testMacro(2);

在上述文本文件上运行sassy将输出以下内容…

$ sassy test.txt
here's how you call a macro:
    variables can be nested to form references to other variables: somevalue
    ...and also nest parameters as with variables: somevalue

here's a call to the same macro with a different parameter:
    variables can be nested to form references to other variables: somevalue
    ...and also nest parameters as with variables: someothervalue

循环

this is how you execute a loop:
%procloop (3) loopCounter;
    this loop will execute &loopCounter. times.
%pend;

...you can also use a variable to set the number of iterations:
%let loopVar0 = first loop;
%let loopVar1 = second loop;
%let loopVar2 = third loop;
%let loopVar3 = fourth loop;
%let numLoops = 4;
%procloop (&numLoops.) counterVar;
    this other loop will execute &counterVar. times, and references a different variable each time: &loopVar&counterVar..
%pend;

在上述文本文件上运行sassy将输出以下内容…

$ sassy test.txt
this is how you execute a loop:
    this loop will execute 0 times.
    this loop will execute 1 times.
    this loop will execute 2 times.

...you can also use a variable to set the number of iterations:
    this other loop will execute 0 times, and references a different variable each time: firstloop
    this other loop will execute 1 times, and references a different variable each time: secondloop
    this other loop will execute 2 times, and references a different variable each time: thirdloop
    this other loop will execute 3 times, and references a different variable each time: fourthloop

安装

以下是安装Sassy所需的操作：

mkvirtualenv sassy
workon sassy

pip install sassylang
