DLT log reader

dltpy - library and utilities for DLT logging

Installing

Requirements (not handled by pip/setuptools)

• native build environment: python3-dev, cmake and a decent c++ compiler supporting c++17.
• fmtlib for native logging and formatting exceptions

Installation

Once the requirements mentioned above are ready, you can install dltpy with pip just as any other python package:

• current master from git:

pip install --user git+https://github.com/Equidamoid/dltpy.git

• last version from pypi:

pip install --user dltpy

• an editable "developer" mode:

git clone https://github.com/Equidamoid/dltpy.git
pip install --user -e dltpy

Using

There are 3 commandline utilities that demonstrate usage of the library:

• dltpy-print prints specified .dlt file as plain text. "text-like" payloads are decoded and printed as text, others are repr()ed
• dltpy-filter filters out unneeded boring messages. Run it with -f IDS:OF YOUR:APPS and enjoy tiny logs that take seconds to load.
• dltpy-receive demonstrates integration with asyncio and direct use of the native module, like dlt-receive. The main difference is that it gracefully reconnects if, for example, your device reboots.

Please note that non-verbose messages are skipped by DltFile since it has no way of decoding the payload.
