pip install pydlt

Common errors

error AttributeError: module 'pydlt' has no attribute 'Dlt' ↓

cause Wrong import: from pydlt import Dlt (Dlt is not a class).

fix

Use from pydlt import DltFile

error TypeError: 'DltFile' object is not iterable ↓

cause Calling DltFile() without opening a file first.

fix

Call dlt = DltFile(); dlt.open('file.dlt') before iterating.

error FileNotFoundError: [Errno 2] No such file or directory: 'example.dlt' ↓

cause File path does not exist or is relative when current directory is unexpected.

fix

Use absolute path or check os.getcwd()

Warnings

gotcha DltFile does not close automatically; always call .close() or use a context manager (not yet supported) to avoid resource leaks. ↓

fix Explicitly call dlt.close() or wrap in try/finally.

gotcha DltLine payload might be bytes; decoding to string requires specifying encoding (e.g., msg.payload.decode('utf-8')) ↓

fix Decode payload manually: payload = msg.payload.decode('utf-8', errors='replace')
