If you have not done so, install astropysics as described in Installing Astropysics, and be sure to run the setup command astpys-setup as described in Setup. Be sure you have IPython installed for the rest of this section to function correctly.
Astropysics uses IPython to provide an interactive environment to run python. To start using astropysics in ipython, just run the helper script ipyastpys - that will run ipython with a customized profile that automatically imports commonly-used parts of of astropysics (and numpy).
The ipyastpys environment also supports “projects”, allowing the interactive environment to be started such that it automatically moves to a given directory and runs a given script. This directory can then hold all necessary data files and the script can load data and store functions to generate plots for the project/paper. A project can be created using the command:
ipyastpys -c projectname
This will create a project named “projectname”, with a directory “/path/to/currentdir/projectname” and script “projectname/projectname.py”. If the directory or script don’t exist, they will be created. A different directory or script name can be used by calling the script as:
ipyastpys -c projectname /path/to/projectdir projectscript.py
Note that the script must be inside the project directory (in the above example, the script’s full path is “/path/to/projectdir/projectscript.py”).
The interactive environment should then be started using:
ipyastpys -p projectname
And it will start ipython in /path/to/projectdir, with the projectscript.py script automatically run inside the interactive environment (the -s option can be used to give projectscript.py any necessary command line arguments).
If a project script does not already exist, it will be generated from a template that allows for easy interactive work to create plots. In the script, add as many functions as necessary with the function decorator plotfunc() (see the template itself for detailed syntax), and then load any necessary data variables at the end of the script. The make_plots() function can then be used to generate the plots by passing it the name of the plot function. The script can also be used at the command line to auto-generate all plots.
Most of the modlues in astropysics have their own tutorials and examples that are relevant to their specific functionality. This is the best place to go to find examples of how to actually use astropysics. See Core Modules and GUI applications for a list of these modules.
