This project allows you to solve the problems in https://en.wikipedia.org/wiki/Human_Resource_Machine without owning the game.
For this you write *.human files, that can't be included by any other .human files, each is a standalone program.
There are the following instructions:
| instruction | description |
|---|---|
| inbox | Read a number from user input |
| output | Output a number as result |
| copyfrom n | Copy the number on register n and write it to the current buffer |
| copyto n | Copy the number from the current buffer to register n |
| add n | Add the number of register n to the current buffer |
| sub n | Subtract the number of register n from the current buffer |
| mul n | Multiply the number of register n with the number from the current buffer and save it to the current buffer |
| bump+ n | Add one to the number of register n and save it to the current buffer and register n |
| bump- n | Subtract one from the number of register n and save it to the current buffer and register n |
| label n | A label where a jump instruction can jump to |
| jump n | Jump to the label m instruction, where n == m |
| jumpzero n | Same as jump n, but only jumps if the number in the current buffer in 0 |
| jumpnegative n | Same as jump n, but only jumps if the number in the current buffer is less than 0 |
There are 10 registers (register 0 to 10), in which you can write and read. The current buffer and the registers store 32 bit signed integers.
To run your program, run
cargo r --release -- <filename.human> <enable_logging> <number1, number2, ...>
Example:
cargo r --release -- "prog.human" 0 100
