🔒 Error while creating a programming language and compiler LLVM

[hollow oriole]

I'm a beginner working on a programming language called HolyS that Idolizes HolyC that was created by Legend Terry Davis, the language is built on python and uses LLVM Lite, it also follows CodeDuckers playlist on YouTube.

The Error:
Traceback (most recent call last):
File "c:\Users\essam\Desktop\HolyS-main\Lang\main.py", line 39, in <module>
c.compile(node=program)

body: BlockStatement

You didnt give body a value.

That's just a type annotation. That doesn't define the name body.

What value do you want it to hold? An empty BlockStatement object?

[hollow oriole]

how do I define it ?

[midnight delta]

=, like you're doing with the other variables.

You need to assign a value to the name.

[hollow oriole]

so body = BlockStatement ?

or body: BlockStatement = something

[midnight delta]

Either. The : part is just a hint to Python about what type you intend for it to be. It doesn't actually "do" anything though. The = is the important part.

[hollow oriole]

alr I'll try to check

@midnight delta I tried gives me the same error

[midnight delta]

Show what you tried.

Sorry, I got distracted with something.

[hollow oriole]

^

[midnight delta]

You wouldn't get the same error with that.

[hollow oriole]

I did tho

[midnight delta]

You may have gotten a different error, but not the same error.

[midnight delta]

You'll likely get a type error at some point since you need () to instantiate the class.

What's the full error message that you're getting?

[hollow oriole]

ohh yeah I got a different error now

You need to instantiate the class.

BlockStatement(). And you'll need to pass in any statements that you want to be a part of the block, if there are any.

[hollow oriole]

I don't understand

[midnight delta]

Replace = BlockStatement with = BlockStatement().

I feel like we're in a rabbit hole here

[midnight delta]

That's another, new error. I've never used that library, so I don't knownwhat causes that.

[hollow oriole]

nvm it

[sleek vine]

The error means one your objects needs a parent.

The traceback says your code went from line 39 from main, into line 24 of compile, into line 48 of visit_program - where it finally went into the library. So there's something wrong in visit_program function with how you make the return_value (because that's the object you pass).
