Instructors

Can read Korean? My blog link here.

Like turing machine, memory with infinite size is provided.

There are 7 instructors in EZLang

1. MEM(N, U = 0). Go to Nth memory. If U is 1, Go to +Nth memory. Use like MEM(3) or MEM(1, 1)
2. SET(V, U = 0). Set current memory to V. If U is 1, Add V to current memory. Use like SET(5) or SET(-1, 1)
3. JLZ(N). Jump to Nth instructor if current memory is less than zero. Use like JLZ(3). Note that first line is 1, not 0.
4. GET(C = 0). Get a number and set current memory to the number. if C is 1, Get a character and set current memory to unicode number of the character.
5. PRT(C = 0). Same as GET, except it prints.
6. HLT(). Halt program.
7. NEG(). Save negative number to current memory.

...And anything following ) is comment.

Example

This is program which get two numbers for input, and print sum of the numbers.

MEM(0) plus. when first made this language
SET(-1)
MEM(1)
GET()
MEM(2)
GET()
MEM(1)
SET(-1, 1)
JLZ(14)
MEM(2)
SET(1, 1)
MEM(0)
JLZ(7)
MEM(2)
PRT()
HLT()

How to use?

How to write new instructor?

First, make new class with this format :

    class Yourclass(Instructor):
        def __init__(self):
            self.ins_name = "(name)"
            self.par_count_min = 0 # minimum parameter
            self.par_count_max = 0 # maximum parameter
        def process(self, param, state):
            super(Yourclass, self).process(param, state)
            #and your code

Second, write your code. You can access to variables with state.variable.

There is five variable you can access, mem_place, mem_list, excuting, ins_place(When get, it is 0-based, and when set, it is 1-based.), output_list, mem(current memory)

Third, add your new instructor in get_instructor_list method of Instructor class.

Done!
