have planet orders request take in a series of item descriptions to create an order

[jreiberkyle]

To support the common use case of creating an order from a search, have planet orders request take in a series of item descriptions to create an order.

Usage:

planet data search --limit 5 PSScene | planet orders request - --name test --clip aoi.geojson --bundle analytic

Implementation notes: ids and item type are taken from the input. There is a check for more than one item type, which at this point results in a failure (the ability to order multiple types could come in a future improvement)

Changes required:

• planet order requests must now allow multiline input where each line is json in addition to ids as the argument
• item-type is only required if the input is IDs

Below is a working example of extracting item type and id from the output of planet data search.

$> planet data search --limit 5 PSScene | python ml.py --items -
PSScene: 20230504_155548_86_24b9
PSScene: 20230504_134550_99_2251
PSScene: 20230504_052537_02_2465
PSScene: 20230504_043314_80_248b
PSScene: 20230504_161301_74_2405

Note: MultiJSON is a hacked up version of JSON, which is in the cli/types.py module. There is more work here in defining a type that can handle both comma separated strings and multiple lines of json.

ml.py

import json

import click


class MultiJSON(click.ParamType):
    name = 'MultiJSON'

    def convert(self, value, param, ctx) -> list:
        if isinstance(value, list):
            conv = value
        else:
            # read from raw json
            # skip this if value is a Path object or something else
            if isinstance(value, str) and (value.startswith('{')
                                           or value.startswith('[')):
                print('hereh')
                try:
                    conv = json.loads(value)
                    if isinstance(conv, dict):
                        conv = [conv]

                except json.decoder.JSONDecodeError:
                    self.fail(
                        'JSON string is not valid JSON. Make sure the entire '
                        'JSON string is single-quoted and string entries are '
                        'double-quoted.')

            # read from stdin or file
            else:
                try:
                    with click.open_file(value) as f:
                        conv = [json.loads(line) for line in f if line]
                except FileNotFoundError:
                    self.fail('File not found.')
                except json.decoder.JSONDecodeError:
                    stream = 'stdin' if value == '-' else 'JSON file'
                    self.fail(f'{stream} does not contain valid JSON.')

        if not len(conv):
            self.fail('JSON cannot be empty.')

        return conv

@click.command()
@click.option('--items', type=MultiJSON(), required=True)
def hello(items):
    for i in items:
        click.echo(f"{i['properties']['item_type']}: {i['id']}")


if __name__ == '__main__':
    hello()
