"""Helper class for dealing with image generation arguments.
The Args class parses both the command line (shell) arguments, as well as the
command string passed at the invoke> prompt. It serves as the definitive repository
of all the arguments used by Generate and their default values, and implements the
preliminary metadata standards discussed here:
https://github.com/lstein/stable-diffusion/issues/266
To use:
opt = Args()
# Read in the command line options:
# this returns a namespace object like the underlying argparse library)
# You do not have to use the return value, but you can check it against None
# to detect illegal arguments on the command line.
args = opt.parse_args()
if not args:
print('oops')
sys.exit(-1)
# read in a command passed to the invoke> prompt:
opts = opt.parse_cmd('do androids dream of electric sheep? -H256 -W1024 -n4')
# The Args object acts like a namespace object
print(opt.model)
You can set attributes in the usual way, use vars(), etc.:
opt.model = 'something-else'
do_something(**vars(a))
It is helpful in saving metadata:
# To get a json representation of all the values, allowing
# you to override any values dynamically
j = opt.json(seed=42)
# To get the prompt string with the switches, allowing you
# to override any values dynamically
j = opt.dream_prompt_str(seed=42)
If you want to access the namespace objects from the shell args or the
parsed command directly, you may use the values returned from the
original calls to parse_args() and parse_cmd(), or get them later
using the _arg_switches and _cmd_switches attributes. This can be
useful if both the args and the command contain the same attribute and
you wish to apply logic as to which one to use. For example:
a = Args()
args = a.parse_args()
opts = a.parse_cmd(string)
do_grid = args.grid or opts.grid
To add new attributes, edit the _create_arg_parser() and
_create_dream_cmd_parser() methods.
**Generating and retrieving sd-metadata**
To generate a dict representing RFC266 metadata:
metadata = metadata_dumps(opt,<seeds,model_hash,postprocesser>)
This will generate an RFC266 dictionary that can then be turned into a JSON
and written to the PNG file. The optional seeds, weights, model_hash and
postprocesser arguments are not available to the opt object and so must be
provided externally. See how invoke.py does it.
Note that this function was originally called format_metadata() and a wrapper
is provided that issues a deprecation notice.
To retrieve a (series of) opt objects corresponding to the metadata, do this:
opt_list = metadata_loads(metadata)
The metadata should be pulled out of the PNG image. pngwriter has a method
retrieve_metadata that will do this, or you can do it in one swell foop
with metadata_from_png():
opt_list = metadata_from_png('/path/to/image_file.png')
