remlang 0.5

rem langauge, which is very comfortable.

Rem Langauge

Just use PyPI. Recommend to install cytoolz before installing Rem to speed up function invocations.

pip install remlang

Some Supported Features

See all features at Inrtoduction.

• Pattern Matching

  Currently support case syntax.

  case expr
      as destruction
      [when condition]
      => statements
  end

  • Dictionary Pattern Matching

  case %{a: b}
      as {a : &b+1} => 1
      as {a : &b }  => 2
  end

  • Function Parameter Destruction

    >> {|(1, 2, c)| c*2} (1, 2, 3)
    => 6

• **Inverted Syntax** (see the priority table in the linked page)

  file . open . write some_text

  . has a high priority while then has a lower one.

  

  

• Into Statement(just like goto)

  

• Currying Function

  

• Scope

• Where Syntax and Block Expression

  
• For Comprehension and For Loop

  

关于中文编程

Rem 支持中文编程, 因为它的tokenizer可以被动态操控，在任意一个Rem模块里，均有一个__compiler__对象， 负责处理输入语句到ast的转换。当下内置了一个无参函数中文编程， 便可以使用中文关键字。

>> call 中文编程
>> 对于 [3, 2] 作为 [甲, 乙] => 甲 * 乙 结束
# 等价于 =>
# case [3, 2] as [甲, 乙] => 甲 * 乙 end
=> 6
