Output Viewer

A viewer (written in python) that receives logging messages from a (C++/Python/Matlab) logger.

Motivation. I write Maya and Matlab plugins. When they crash, I lose my logging output. Also, at times they are buggy and won't print anything.

The viewer

• output_viewer.pyw

It listens on a local socket port, receives, and prints messages. Run with pythonw to avoid opening a command window.

The following API communicates with it in different languages.

Python

A simple client example

• python_client\output_client_example.py

Matlab

Use

• matlab_client\mlog.m
• matlab_client\mlogn.m

A settings file

• matlab_client\mlog.settings

that holds a flag (0/1) if to send to the viewer or not. The viewer has a convenient checkbox to set it. The file is in the same directory as the matlab client, and the path to it needs to be set in output_viewer.json so the viewer would know where to look.

C++

A client example, which uses an elaborate logger class (e.g., has a method println)

• cpp_client\test\test_logger.cpp

Unlike the matlab interface, we use here a global Log variable, which has a method set_send_to_viewer() to turn on/off sending output to the viewer (so there's no need for a settings file).
