Local running tool

.. argparse::

:prog: artiq_run

Remote Procedure Call tool
|
|
------------------------------
|
|
|

.. argparse::

:ref: artiq.frontend.artiq_rpctool.get_argparser
|
|
:prog: artiq_rpctool
|
|
|
|
This tool is the preferred way of handling simple ARTIQ controllers.
|
|
Instead of writing a client for very simple cases you can just use this tool
|
|
in order to call remote functions of an ARTIQ controller.
|
|
|
|
* Listing existing targets
|
|
|
|
The ``list-targets`` sub-command will print to standard output the
|
|
target list of the remote server::
|
|
|
|
$ artiq_rpctool.py hostname port list-targets
|
|
|
|
* Listing callable functions
|
|
|
|
The ``list-methods`` sub-command will print to standard output a sorted
|
|
list of the functions you can call on the remote server's target.
|
|
|
|
The list will contain function names, signatures (arguments) and
|
|
docstrings.
|
|
|
|
If the server has only one target, you can do::
|
|
|
|
$ artiq_rpctool.py hostname port list-methods
|
|
|
|
Otherwise you need to specify the target, using the ``-t target``
|
|
option::
|
|
|
|
$ artiq_rpctool.py hostname port list-methods -t target_name
|
|
|
|
* Remotely calling a function
|
|
|
|
The ``call`` sub-command will call a function on the specified remote
|
|
server's target, passing the specified arguments.
|
|
Like with the previous sub-command, you only need to provide the target
|
|
name (with ``-t target``) if the server hosts several targets.
|
|
|
|
The following example will call the ``set_attenuation`` method of the
|
|
Lda controller with the argument ``5``::
|
|
|
|
$ artiq_rpctool.py ::1 3253 call -t lda set_attenuation 5
|
|
|
|
In general, to call a function named ``f`` with N arguments named
|
|
respectively ``x1, x2, ..., xN``.
|
|
|
|
You must pass them as a Python iterable object::
|
|
|
|
$ artiq_rpctool.py hostname port call -t target f '(x1, x2, ..., xN)'
|
|
|
|
You can use Python syntax to compute arguments as they will be passed
|
|
to the ``eval()`` primitive::
|
|
|
|
$ artiq_rpctool.py hostname port call -t target f '(x*3+5 for x in range(8))'
|
|
$ artiq_rpctool.py hostname port call -t target f 'range(5)'
|
|
|
|
If you only need one argument, you don't need to pass an iterable, a
|
|
single value is accepted.
|
|
|
|
If the called function has a return value, it will get printed to
|
|
the standard output if the value is not None like in the standard
|
|
python interactive console::
|
|
|
|
$ artiq_rpctool.py ::1 3253 call get_attenuation
|
|
