Description
GammaRay inspects runtime internals of a Qt-application, such as:
Object tree, properties, signal/slots, widgets, models,
graphics views, javascript debugger, resources,
state machines, meta types, fonts, codecs, text documents
When run without any options, gammaray will present a list of running Qt-applications from which you can
attach the selected injector. Else, you can attach to a running process by specifying its pid, or you
can start a new Qt-application by specifying its name (and optional arguments).
Examples
Run gammaray on the Qt-application "qtfoo" with command line arguments 'arg1' and 'arg2':
% gammaray /path/to/qtfoo arg1 arg2
Invoke gammaray on the Qt-application running with pid 1234:
% gammaray --pid 1234
Invoke gammaray on with injector gdb on Qt-application running with pid 1234:
% gammaray --injector gdb --pid 1234
Exit Status
Exits with 0 under normal operation; otherwise, exists with a positive integer indicating a problem
occurred while launching or attaching an injector.
Name
GammaRay - Qt-application inspection and manipulation tool.
Options
--help
Print help message and exit.
--version
Print version information and exit.
-p,--pid<pid>
Attach to running Qt application with the specified pid.
-i,--injector<injector>
Set the specified injection type.
Supported injectors are:
preload (Linux, Mac OS)
gdb (Linux. requires gdb to be installed)
lldb (Linux. Mac OS, requires lldb to be installed)
style
windll (Windows)
--inprocess
Use the Gammaray 1.x in-process UI. This is not necessary in most cases, apart from using tools that
do not work remotely.
--inject-only
This will only inject the GammaRay probe into a process, but not start the GammaRay UI. This is
useful for example when doing remote debugging on embedded devices.
--listen<address>
Specify on which network address the GammaRay server should listen, default is
GAMMARAY_DEFAULT_ANY_TCP_URL (ie. tcp://0.0.0.0, all of ipv4, use tcp://[::] for all ipv6). This can
be used for example on Windows to avoid firewall warnings by setting the address to 127.0.0.1 if you
don't need remote access.
--no-listen
Disables the GammaRay server. This implies --inprocess as there is no other way to connect to the
GammaRay probe in this case.
--list-probes
List all installed probes.
--probe<abi>
Explicitly specify which probe to use. You should use this if you have more than one probe installed
(e.g. one for Qt4 and one for Qt5), until probe ABI auto-detection is implemented.
--connect<host[:port]>
Connect to a target with an already injected GammaRay probe. Useful for example for remote debugging.
--self-test[injector]
Run GammaRay self-tests, if an injector is specified only that specific one will be tested.
The exit code is 0 on success, and 1 otherwise.
