When I run the program (.bf) in the interpreter it thinks there is a , when there is none
Hello?
tawdry crater
Hello. How do you know the interpreter things there is a comma? Is there an error message you can provide?
sacred grail
There is none thanks to my error checking
It gives me an Argument error 1
Run func:
def run_code(self):
self.code_text = self.codeinput.toPlainText() # Retrieve text from codeinput
self.arg_text = self.arginput.toPlainText()
self.need_arg = False
self.invalid_arg_char = False
self.err_code = None
backend.code = self.code_text
backend.arg = self.arg_text
try:
self.errindex = backend.code.find(",")
self.need_arg = True
except ValueError as error:
self.need_arg = False
print(error)
if self.need_arg and not self.arg_text:
self.outputbox.setText("Argument Error 1: The program requires an argument but has not been given one")
self.err_code = 1
# Check if the argument contains invalid characters
if self.need_arg:
for char in backend.arg:
if char not in backend.ascii_table:
self.outputbox.setText("Argument Error 2: A character in the argument is not a valid character in Brainfuck")
self.err_code = 2
else:
pass
if self.err_code == 1:
print("ERR 1")
elif self.err_code == 2:
print("ERR 2")
else:
self.outputbox.setText("")
backend.run()
self.outputbox.setText(backend.output_result)
I'm using PyQt5

Can you paste the full error?
nm, this one?
Argument Error 1: The program requires an argument but has not been given one

Print out the value of backend.code at this point:
try:
self.errindex = backend.code.find(",")
Worth noting:
https://docs.python.org/3/library/stdtypes.html#str.find
Return the lowest index in the string where substring sub is found within the slice s[start:end]. Optional arguments start and end are interpreted as in slice notation. Return -1 if sub is not found.
-1 will be Truthy for your use.

Before you link the v3 docs
Everything above line 189 is a u'' string
Those don't exist in Python 3, right?
not that the behavior of this particular function would be any different, but just in case
tawdry crater
backend.code = self.code_text
backend.arg = self.arg_text
try:
self.errindex = backend.code.find(",")
self.need_arg = True
except ValueError as error:
self.need_arg = False
print(error)
if self.need_arg and not self.arg_text
I'm just looking at the code provided. An assignment of self.code_text to backend.code. Then a try/except that always sets self.need_arg to True. Then a condition that will always fire.
sacred grail
why
fiery valley
Because you told it to
sacred grail
where
tawdry crater
What would error in the try/except?
sacred grail
hold on
sacred grail
What would error in the try/except?
none
I did this to test:
def test():
p = 1
code = "+++++.[-]."
try:
p = code.find(",")
print("There is a ','")
except Exception as error:
print(error)
print("There is not a ','")
test()
and it returned:
There is a ','
So what are you expecting to error? code.find(",") isn't erroring, it is returning -1.
sacred grail
oooooooh
tawdry crater
-1 means that , was not found.
