This is the command pycallgraph that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
pycallgraph - Python Call Graph
SYNOPSIS
pycallgraph [OPTION]... OUTPUT_MODE [OUTPUT_OPTIONS] python_file.py
DESCRIPTION
pycallgraph is a program that creates call graph visualization from Python scripts.
OUTPUT_MODE can be one of graphviz, gephi and json. python_file.py is a python script that
will be traced and afterwards, a call graph visualization will be generated.
GENERAL ARGUMENTS
<OUTPUT_MODE>
A choice of graphviz, gephi and json.
-h, --help
Shows a list of possible options for the command line.
-v, --verbose
Turns on verbose mode which will print out information of pycallgraph's state and
processing.
-d, --debug
Turns on debug mode which will print out debugging information such as the raw
Graphviz generated files.
-ng, --no-groups
Do not group modules in the results. By default this is turned on and will visually
group together methods of the same module. The technique of grouping does rely on
the type of output used.
-s, --stdlib
When running a trace, also include the Python standard library.
-m, --memory
An experimental option which includes memory tracking in the trace.
-t, --threaded
An experimental option which processes the trace in another thread. This may or may
not be faster.
FILTERING ARGUMENTS
-i, --include <pattern>
Wildcard pattern of modules to include in the output. You can have multiple include
arguments.
-e, --exclude <pattern>
Wildcard pattern of modules to exclude in the output. You can have multiple include
arguments.
--include-pycallgraph
By default pycallgraph filters itself out of the trace. Enabling this will include
pycallgraph in the trace.
--max-depth
Maximum stack depth to trace. Any calls made past this stack depth are not included
in the trace.
GRAPHVIZ ARGUMENTS
-l <tool>, --tool <tool>
Modify the default Graphviz tool used by pycallgraph. It uses "dot", but can be
changed to either neato, fdp, sfdp, twopi, or circo.
EXAMPLES
Create a call graph image called pycallgraph.png on myprogram.py:
pycallgraph graphviz -- ./myprogram.py
Create a call graph of a standard Python installation script with command line parameters:
pycallgraph graphviz --output-file=setup.png -- setup.py --dry-run install
Run Django's manage.py script, but since there are many calls within Django, and will
cause a massively sized generated image, we can filter it to only trace the core Django
modules:
pycallgraph -v --stdlib --include "django.core.*" graphviz -- ./manage.py syncdb --noinput
Use pycallgraph online using onworks.net services
