''''+-''', or '''ID''', is a [[Joke language list|joke language]] created by [[User:Anonymous]] in 2017. == Commands == +- consists of a single accumulator, along with 2 single-character commands to change it. Using other characters besides these will result in the string <code>Error!</code> being alerted to console or an alert box. Note that this does not stop the program from continuing its execution. {| class="wikitable" |- ! Command !! Action |- | <code>+</code> || Increments the accumulator. |- | <code>-</code> || Decrements the accumulator. |} == Examples == Sets the accumulator to 1: + to 5: +++++ to 64: ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ == Interpreters == === Java === public static String id(String p){ int a = 0; for(int i = 0; i < p.length(); ++i){ switch(p.charAt(i)){ case '+': ++a; break; case '-': --a; break; default: System.err.println("Error!"); } } return <nowiki>'</nowiki>'; } } === JavaScript === function id(p){ var a = 0; for(var c of p){ switch(c){ case '+': a++; break; case '-': a--; break; default: alert('Error!'); } } return <nowiki>'</nowiki>'; } === Python 3 === def id(): acc = 0 while True: prg = input('\n+-> ') for cmd in prg: if cmd == '+': acc += 1 elif cmd == '-': acc -= 1 else: print('Error!'); break === C === #include <stdio.h> int main() { int ch, ax = 0; while((ch = getchar()) { ax += (ch == '+') - (ch == '-'); } } = +-= = '''+-=''', or '''IDPL''', is the same as +-, except the <code>=</code> operator is added for output. == Commands == {| class="wikitable" |- !

This makes it a lot more usable == Commands == <code>!</code> and <code>&</code> have been removed. {| class=wikitable ! Command !! Function |- | <code>+</code> || Increments the accumulator. |- | <code>-</code> || Decrements the accumulator. |- | <code>=</code> || Prints the accumulator's value. |- | <code>*</code> || Prints the accumulator as an ASCII character. |- | <code>@</code> || Inputs the next integer to the accumulator. |- | <code>%</code> || Inputs the next character in ASCII to the accumulator. |- | <code>/</code> || Sets the accumulator to 0. |- | <code>#</code> || Prints a newline. |- | <code>(x)</code> || Does the previous command x amount of times. This makes <code>!</code> and <code>&</code> redundant, thus being removed. You can also keep the x to repeat the command the number of times in the accumalator. |- | <code>&lt;</code> || Moves the pointer one command back. a command with a <code>(x)</code> after it will be counted as one command (e.g.<code>+(5)&lt;</code> will constantly increment the accumulator by 5). You can also use <code>&lt;(x)<</code> to go back multiple commands. |} ==Examples== ===[[Cat Program]]=== this is a simple [[Cat Program]] for one character %* ===[[Truth Machine]]=== First, it takes in an integer input and prints it then it will move the pointer back the number in the accumulator, meaning, if the accumulator is 0 then the program will go on without doing anything and terminate, but if the accumulator is 1 then the pointer will go back one to the command <code>=</code> which will output the accumulator, which is one, and repeat. @=<(x) ==Interpreters== WIP [[Category:2017]] [[Category:Unusable for programming]] [[Category:Implemented]] [[Category:Joke languages]]'
