伍什(wǔshí, or literally five and ten with 'human' radical) is an esolang using CJK characters as commands.

About CJK characters

According to context, CJK characters may also be called Hanzi(for Chinese), Kanji(for Japanese), or Hanja(for Korean).

You may have noticed that the characters 伍 and 什 consists of 2 parts: 亻and another part. This is because Many of CJK characters are phono-semantic, meaning that parts of the character indicates its (ancient) pronunciation and other parts indicates its meaning category. For instance, 伍 consists of 亻 and 五, where 亻(actually a flat 人) shows that it has something to do with humans, and 五(wǔ) shows that it sounds similar to wǔ. As a result, 伍 resembles queue / army.

Our goal is to make use of the phonetic part. Think about it: the semantic part shared by many chars could pe the operator; why don't we see the phonetic part as the operand?

Commands

Under construction

Chars that can be separated into following parts (though not necessary phono-semantic), or parts followed by some valid expressions, are seen as commands. Commands can be separated by newline or any full-width unpaired punctuation such as ，。？！；：—…. Full-width brackets like （）【】 can be used to mark blocks for branching commands(while half-width () is used to prioritize operations). Full-width quotes like ‘’“” are used to mark literal strings(escapes like \n, \‘ or \u4e00 are supported), the only difference is that “” can mark multiline ones, just as what triple quote does in Python.

When we cone across parts/chars not seen before, we assume it is a new variable, just like in Python.

A number literal value can (but not necessarily) be written in chars. 3076 == 三〇七六 == 三0七6, and 24.91 == 二四.九一. 零 and 点/點 are avoided for they have parts identical to operators. There is a constant keyword 不, which is equal to any False value(including 0, 0.0 and ‘’), so 广[Expr] can be replaced with ([Expr])肧.

Priorities works differently according to how you write the code. A single character is considered a whole, just like 㭅 as (-3), so even a prior operator cannot get its operand as its operand; but when you tear it apart, everything works according to priority. This may save you some brackets while causing some headache. Example: 三㭅氿 → 3 -3 *9 → (3 - 3) * 9 → 0, while 三木三氿 → 3 - 3 *9 → 3 - 3 * 9 → -24.

Note that 'associativity' only means that if the operator is separate from operand how should it associate. It has nothing to do with its position in a compound character.

Commands start with #. Like Python, you may also create a single unassigned string as comment.

Characters may appear different in Traditional/Simplified Chinese, Japanese or Korean. Please take this into account when programming with this.

Component Commands

Operator part	Associativity	Meaning	Example
人(亻)	Left	Input to variables. The operand is taken as a single-char variable name. Any input is considered strings, separated by newlines(not included). (Then the name of this esolang is actually a Syntax Error: You cannot input into a number!) After each input, stdin(人) is returned so more variables receive input.	你少 or 人尔少 takes 2 inputs and stores them in var 尔, 少.
言(讠)	Left	Output from operand. The operand can be literal numbers, literal strings, variables or complex expressions. After each output, stdout(言) is returned so more variables receive output. Note that 言 adds no indentations, so you have to add spaces and ‘\n’s by hand.	說口, 说口， 言兑口 or 讠兑口 outputs value of var 兑, 口.
口	Right	Assignment. Takes its operand and assign it to the character on the left. Inferior to 金/木. Not to be confused with 囗.	天口上口下叭 assigns 天, 上 and 下 with integer 8.
金(钅)	Left	Addition. Adds its operand to its left value and returns the result. Also used to concatenate strings, when either left value or operand is a string.	三釚钟 or 三金九金中 returns 3 + 9 + 中.
木	Left	Subtraction.	三㭅样 or 三木三木羊 returns 3 - 3 - 羊.
水(氵)	Left	Multiplication. Prior to 金/木. Also used to repeat strings, where its operand is the number.	三氿洗, 三氵九氵先 or 三水九水先 returns 3 * 9 * 先.
火(灬)	Left	Float division. As in Python, any input returns a float. Prior to 金/木.	三燤, 三火萬 or 三火万 returns 3 / 10000 = 0.0003.
土	Left	Modulo. Unlike in some languages, it accepts integer or float. Prior to 金/木.	三四五六圲 returns 3456 % 1000 = 456.
日	Left	Greater than. If Left value is greater than operand(by value for values, or by Unicode dict order for strings), return 1, else return 0.	三旦 returns 3 > 1 = 1.
月	Left	Equals. If Left value is equal to operand, return 1, else return 0.	九肍 returns 1.
明	Left	Greater than or equals. Can be split into 日月.	十盟, 十明皿 or 十日月皿 returns 1 for any 皿 value <= 10.
广	Right	Not(by boolean). Returns 1 if the operand is False value, else return 1. Can concatenate with 日, 月 etc.	三㡺 return 3 <= 1 = 0.
辵(辶)	-	If statement. Takes its operand as condition, and if it returns False value, the If block is jumped over. Must be paired up with 走.	边【...】䞜 is executed once if var 力 is not 0 or empty string.
走	-	'Jumpback' operation. Takes its operand as condition, and if it returns True value the flow jumps back to the 辵 it is paired up with.	In the last example, 走 receives 不, so it is simply an If-equivalent. To create endless loop you can use 辷【...】走一.
石	-	Break operation. Takes its operand as conditon, and if it returns True value the flow jumps out of the 辵-走 pair. If 石 is out of any pair, it is an NOP.	破 will do that if 皮 is True value.
刀(刂)	Left	Single character slicing. Left value should be a string, and the operand should be one single index integer(starting from 0). Returns a single-char string(SCS). If the number is out of index, the operation simply returns empty string ‘’.	‘不要断章取义’𬺳 returns ‘不要断章取义’[1] = ‘要’.
示(礻)	Right	Int and SCS mutual convertion by Unicode value. If length of string operand is other than 1, returns -1; if int is out of current Unicode range(0 to 0x10ffff), returns empty string ‘’.	示一九九六八 = ‘一’, while 示‘一’ = 19968.

言‘Hello, world!’

This outputs a single 问世界安好.

99 bottles of beer (without final verse)

  言‘ of beer.\nTake one down, pass it around, ’
  甲口甲本      # 本 = 木一. Note that this cannot be compressed as 甲呷本, as 甲呷 will be executed first.

Intepreter

There is unlikely any intepreter for this esolang, because dividing CJK characters alone is not only huge work, but can be ambiguous at times. But if we introduce more restrictions, it is still possible to make one using some online glyph database.
