tspin is a log file viewer that automatically applies syntax highlighting to make logs more readable. It detects common log formats and colorizes elements like timestamps, log levels, IP addresses, URLs, and JSON structures without requiring manual configuration.
Follow mode (-f) monitors log files in real time, highlighting new entries as they appear, similar to tail -f but with color. The tool can also read from standard input via pipes, integrating into existing logging pipelines.
A built-in pager allows scrolling through log files interactively. Custom highlighting rules can be defined through a configuration file for non-standard log formats.
