What is KoiLang

KoiLang is a markup language while is easy to read for people. There is an simple example.

#hello KoiLang
I am glad to meet you!

In KoiLang, file is divided into 'command' part and 'text' part. The formation of command part is like C preprocessor directive, using '#' as starting. And text is surrounding commands.

#command "This is a command"
This is a text.

Each command can have several arguments behind the command name. Valid argument type include integer, float, literal and string.

#arg_int    1 0b101 0x6CF
#arg_float  1.0 2e-2
#arg_literal __name__
#arg_string "A string"

Here "literal" is a valid python variety name containing letter, digit, underline and not starting with digit. Usually it is same as a string.

There is another kind of arguments -- keyword arguments which formation is as this:

#kwargs key(value)

And another format:
#keyargs_list key(item0, item1)

And the third:
#kwargs_dict key(x: 11, y: 45, z: 14)

All the arguments can be put together

#draw Line 2 pos0(x: 0, y: 0) pos1(x: 16, y: 16) \
    thickness(2) color(255, 255, 255)

What can Kola module do

Kola module provides a fast way to convert KoiLang command to a python function call.

Above command #draw will convert to function calling below:

draw(
    "Line", 2,
    pos0={"x": 0, "y": 0},
    pos1={"x": 16, "y": 16},
    thickness=2,
    color=[255, 255, 255]
)
