.TH WESTON-DEBUG 1 "2018-09-11" "Weston @version@"
.SH NAME
weston-debug \- a tool for getting debug messages from compositor.
.SH SYNOPSIS
.B weston-debug [options] [names]
.
.\" ***************************************************************
.SH DESCRIPTION
.B weston-debug
is a debugging tool which uses weston_debug_v1 interface to get the
debug messages from the compositor. The debug messages are categorized into different
debug streams by the compositor (example: logs, proto, list, etc.,) and the compositor
requires a file descriptor to stream the messages.
This tool accepts a file name or a file descriptor (not both) and any desired debug stream
names from the user as command line arguments and subscribes the desired streams from the
compositor by using the weston_debug_v1 interface. After the subscription, the
compositor will start to write the debug messages to the shared file descriptor.
If no file name or file descriptor argument is given, the tool will use the stdout file
descriptor.
