Overview
log_viewer is an ncurses text UI for viewing rosout logs.
Motivation
Receive, filter, and navigate through all published rosout log messages from within a terminal to support debugging a robot live.
Problem
Many rosout log messages don't get printed to the terminal in the normal course when there are lots of nodes/messages. There is also not a convienient way to filter and navigate through them in real time.
swri_console provides most of the desired functionality very well, but is Qt based and requires a graphical interface.
Solution
log_viewer is very similar in concept and design to swri_console, but uses ncurses instead of Qt for the interface.
Log messages can be filtered based on:
- log level
- node
- whitelist text filter
- exclude text filter
log_viewer also supports text searches and jumping from match to match.
Log messages are copied to the clipboard by selecting them.
Like swri_console, log_viewer doesn't need roscore to start and will automatically connect/reconnect with roscore when it becomes available.

Mouse Support
There is limited mouse support for selecting log messages and enabling/disabling the log level and node filters. Due to a bug in the currently distributed version of ncurses, mousewheel scrolling only works in the up direction.
