5.1.1 Naming Rules🔗

To extend Naming Rules, specifically there are:

Character

Connotation

Elucidation

Example

􏷫 as radical

resembles 􏿴

Has the similar function process as it resembling and the type of output is same as 􏿴 accordingly.

􏼓 􏼎 􏼏 􏿝

􏷩 as radical

resembles 􏿫

Has the similar function process as it resembling and the type of output is same as (􏿫) accordingly.

􏿜

 as component

general subset or cousion

Returns a new list with elements produced from the input list.(Implies the input data and output data are the same type.)

𰂋 􏾜 􏾛 𠆯 􏹈 􏷍?

 as component

serial subset

Returns a new list with elements serially produced from the input list.(Implies the input data and output data are the same type.)

􏾝 􏾺 𨚞 􏹋

􏸋 as component

serial subset of lists

Returns a new list with elements serially produced from the input lists.(Implies the multiple input data and output data are the same type.)

左􏸒

 as component

split input list to values

Implies the type of output data is values().

􏸄 􏸃

􏸍 as component

same as /入

Implies the type of input data is function.

􏹃 􏹌 􏹅 􏹇 􏹂

 as component

product data

Manufactures data and product new one, implies the type of output data is not same as input.

􏷎

Phrase

-

-

-

suffixed with 

split data to values

􏹈分

Punctuation

-

-

-

suffixed with *

strengthen

Strengthen the process, thus the data of output may become longer, and the type may be changed accordingly.

弓* 􏹂* 􏼏*

suffixed with ~

soften

Soften the process, thus the output data shorter.

5.1.2 双, 㐅, 􏿴, 􏿫, 阴, 阳 🔗

Abstractly, we can pair two data together. Integrally, it is called . Separately, the position where set the first data is call , the second is call .

Further more, if we put another to position of the former , we get a linked data. Likewise, the linked data can be extended as long as you want. By this way, if we leave of the ending to be empty(), we get a data called 􏿴; if not, we call it 􏿫.

: : resembles the picture of human’s right hand trying to hold an object. Two human hand here stand for an object with including two holding data.
zi
: simplified from . : simplified from , which means empty.
zi
􏿴: the reaching to left bottom means multiple linked together, means ending with empty().
zi
􏿫: resembles 􏿴 except substituting with , which means the ending position is not empty().
zi
: : means sun, implicitly means the former part of an object, or the position aspect of an object. Ref to wiki.
