Pinyin

Pinyin is a fungeoid invented by User:None1 that uses Chinese characters and Pinyin (a way of representing the pronounciation of Chinese characters using Latin letters).

To avoid ambiguity, "this esolang" instead of "Pinyin" is used when referring to the esolang.

Memory

This esolang has a stack with unbounded signed integers. Popping from it returns 0.

The upper edge and left edge of the grid is solid, like Nopfunge Solid.

Syntax

Parts of a Pinyin

To know the syntax of the esolang, you have to learn the three parts of a Pinyin: tone, consonant part and vowel part. It's hard to explain that to foreigners (non-Chinese people), so examples are used to help understanding.

Examples of 3 parts of a Pinyin

Character	Tone	C. Part	V.Part
一	1	y	i
二	4	/	er
的	0	d	e
我	3	w	o
人	2	r	en

Note: For simplicity, ü is the same as u in this esolang.

Commands

In this esolang, a command is a Chinese character.

Unlike most 2D esolangs, one command has multiple effects created by different parts of the character's Pinyin.

The tone decides what direction the IP is facing after the command is executed:

Caption text

Tone	Direction change
0	Random
1	Clockwise 90°
2	180°
3	Counterclockwise 90°
4	Unchanged

The vowel part decides other effects except changing the IP's direction.

Vowel part effects

Vowel part	Effect
a	Pop stack and output as integer
o	Pop stack and output as Unicode character
e	Input an integer and pushes into stack
i	Input a character and pushes it's Unicode value into stack
u	Pop a,b, pushes a+b
ai	Pop a,b, pushes b-a
an	Pop a,b, pushes a*b
ang	Pop a,b, pushes b%a
ao	Pop a,b, pushes floor(b/a)
ei	Pop a,b, pushes ceil(b/a)
en	Pushes random integer from 0 to 1 into stack
ui	Pop a,b, pushes b**a
un	Pop a,pushes the number of decimal digits in a
in	Duplicate top
eng	Push the number of elements in the stack
ong	Pop a,b, pushes a&b
ing	b
ui	Pop a,b, pushes a^b
ou	Pop a, pushes ~a
er	Pushes 1
i/u+any other vowel part	Equivalent to that vowel part
Other	NOP

The consonant part decides the condition for this command to be executed. If the condition isn't satisfied, the command is simply a NOP.

Consonant part conditions

Consonant part	Condition
No consonant part	Never satisfied
b	If stack is empty
p	If stack is nonempty
m	If stack top is zero
f	If stack top is nonzero
g	Pop a,b, b<a
k	Pop a,b, b>a
h	Pop a,b, b<=a
j	Pop a,b, b<=a
q	Pop a,b, b==a
x	Pop a,b, b!=a
Other	Unconditional

Examples

Hello, world!

we assume that the vowel for eg. 丢(diu1) is iu, not u.
