A simple class to help run miriad tasks.
It makes no attempt to verify calling signatures of miriad tasks like other miriad packages (mirpy for instance). It also operates on the string invocation of miriad tasks. Operating this way does not clash with python keywords (in or map for example).
Some attempts are made to expose miriad options as attributes to the class. For instance you can access keywords of the calling miriad string by simply treating it as an attribute. Assuming a variable called atlod containing the result of a atlod miriad task, then atlod.out will return the value of the out keyword of the calling string.
It can be installed using pip following:
pip3 install git+git://github.com/tjgalvin/pymir.git#egg=pymir
Assuming a variable called uv whose value is the path to a miriad visibility file, then that uv-file can be imaged with:
invert = mirstr(f"invert vis={uv} options=mfs,sdb,double,mosaic offset=3:32:22.0,-27:48:37 stokes=i imsize=6,6,beam map={uv}.map beam={uv}.beam").run()
The trailing .run() will execute the task. Using print() on the variable invert will print not only the invocation string, but also the output of invert.
Attributes of the invocation string can be accessed either explicitly through the attribute method (invert.attribute('map')) or implicitly as an attribute itself (invert.out).
There exists a small interface to expand an invocation string or attempt to overwrite some component. The over keyword can be used when creating a mirstr to replace key/value pairs to a invocation string, or add to it. For instance
invert_kwargs = {"imsize":"3,3,beam", "stokes":"i"}
invert = mirstr(f"invert vis={uv} options=mfs,sdb,double,mosaic offset=3:32:22.0,-27:48:37 imsize=6,6,beam map={uv}.map beam={uv}.beam", over=invert_kwargs).run()will update the value of the imsize key to 3,3,beam and add the stokes keyword.
