# Command line interface for the coloredlogs package. # # Author: Peter Odding <peter@peterodding.com> # Last Change: December 15, 2017 # URL: https://coloredlogs.readthedocs.io """ Usage: coloredlogs [OPTIONS] [ARGS] The coloredlogs program provides a simple command line interface for the Python package by the same name. Supported options: -c, --convert, --to-html Capture the output of an external command (given by the positional arguments) and convert ANSI escape sequences in the output to HTML. If the `coloredlogs' program is attached to an interactive terminal it will write the generated HTML to a temporary file and open that file in a web browser, otherwise the generated HTML will be written to standard output. This requires the `script' program to fake the external command into thinking that it's attached to an interactive terminal (in order to enable output of ANSI escape sequences). If the command didn't produce any output then no HTML will be produced on standard output, this is to avoid empty emails from cron jobs. -d, --demo Perform a simple demonstration of the coloredlogs package to show the colored logging on an interactive terminal. -h, --help Show this message and exit.
