# Rem Language
Just use **PyPI**. Recommend to install `cytoolz` before installing Rem to speed up function invocations.
```shell
pip install remlang
```

## Some Supported Features
See all features at [Inrtoduction](https://github.com/thautwarm/Rem/blob/ebnfparser2.0/intro.md).
- [Pattern Matching](https://github.com/thautwarm/Rem/blob/ebnfparser2.0/intro.md#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**](https://github.com/thautwarm/Rem/blob/ebnfparser2.0/intro.md#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](https://github.com/thautwarm/Rem/blob/ebnfparser2.0/intro.md#into-statement)(just like `goto`)
[](https://github.com/thautwarm/Rem/blob/ebnfparser2.0/overview-figs/into.png)
- [Currying Function](https://github.com/thautwarm/Rem/blob/ebnfparser2.0/intro.md#functionlambda)
[](https://github.com/thautwarm/Rem/blob/ebnfparser2.0/overview-figs/lambda.png)
- [Scope](https://github.com/thautwarm/Rem/blob/ebnfparser2.0/intro.md#scope)
- [Where Syntax and Block Expression](https://github.com/thautwarm/Rem/blob/ebnfparser2.0/intro.md#where-syntax)
[](https://github.com/thautwarm/Rem/blob/ebnfparser2.0/overview-figs/for.png)

## 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
```
