=== STILL TRYING STUFF, AWFULL CODE ===
The grasp grammar is something like python with arrow function definition
now it can parse and run
class Person
__init__(self, name) ->
self.name = name
hello(self) ->
print(self.name)
__getitem__(self, item) ->
return item
person = Person("oguz")
person.hello()
print(person[0] + 1)
Project consists of three parts
=== parse.py ===
This is something like the pyparsing written from scratch
=== grasp.py ===
This is the compiler written using parse.py, which generates stack machine codes. As an example the class definition will be translated into:
class
dup
setglobal Person
jmp l1
l2:pushlocal 0
pushlocal 1
str name
swp
setfield
pushglobal None
return
l1:dup
str __init__
function l2 0
setfield
jmp l3
l4:pushglobal print
pushlocal 0
str name
getfield
call 1
pop
pushglobal None
return
l3:dup
str hello
function l4 0
setfield
jmp l5
l6:pushlocal 1
return
pushglobal None
return
l5:dup
str __getitem__
function l6 0
setfield
pop
pushglobal Person
str oguz
call 1
setglobal person
pushglobal person
str hello
getmethod
swp
call 1
pop
pushglobal print
pushglobal person
str __getitem__
getmethod
swp
int 0
call 2
str __add__
getmethod
swp
int 1
call 2
call 1
pop
=== vm.cpp, vm.h ===
This part is the vm code, interprets the bytecode. Bytecode is not binary for now, that will be done in finalization of the project
