Validate that the argument is a number over a given range. By default, it is (0, +inf)

Note

This function can be used to directly create argparse typing for numbers within a specified range using a lambda function such as:

eqopts.add_argument(
  FLAG_TEMP,
  action='store',
  type=lambda x:parserutils.type_ranged_num(x, top=423, bottom=273),
  metavar='KELVIN',
  help='Simulation temperature for MD equilibration step')

Parameters

arg (str) – The argument to validate
top (float or int) – The upper limit of the allowed range
bottom (float or int) – The lower limit of the allowed range
top_allowed (bool) – Whether arg may take the top value or not (whether the upper limit is inclusive or exclusive)
bottom_allowed (bool) – Whether arg may take the bottom value or not (whether the bottom limit is inclusive or exclusive)
typer (callable) – Should be one of the built-in float or int functions and defines the type of the value returned from this function.

class schrodinger.application.matsci.parserutils.NoArgCustomAction(*args, **kwargs)¶

Bases: argparse.Action

An action that allows giving an argparse flag a custom action so that the flag does not require an argument

One possible use is the implementation of a flag like ‘-doc’ which immediately performs an action when it is found on the command line - such as printing out detailed documentation and then exiting. This avoids the user having to specify any other flags even if they are marked as required.

__init__(*args, **kwargs)¶

class schrodinger.application.matsci.parserutils.KeyPairDict¶

Bases: dict

This is a subclass of dict so that the {a:b} can be displayed as “a=b” (e.g, as the help message”

__contains__(key, /)¶: True if the dictionary has the specified key, else False.

__init__(*args, **kwargs)¶

__len__()¶: Return len(self).

clear() → None. Remove all items from D.¶

copy() → a shallow copy of D¶

fromkeys(value=None, /)¶: Create a new dictionary with keys from iterable and values set to value.

get(key, default=None, /)¶: Return the value for key if key is in the dictionary, else default.

items() → a set-like object providing a view on D’s items¶

keys() → a set-like object providing a view on D’s keys¶

pop(k[, d]) → v, remove specified key and return the corresponding value.¶: If key is not found, d is returned if given, otherwise KeyError is raised

popitem()¶

Remove and return a (key, value) pair as a 2-tuple.

Pairs are returned in LIFO (last-in, first-out) order. Raises KeyError if the dict is empty.

setdefault(key, default=None, /)¶

Insert key with a value of default if key is not in the dictionary.

Return the value for key if key is in the dictionary, else default.

update([E, ]**F) → None. Update D from dict/iterable E and F.¶: If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

values() → an object providing a view on D’s values¶

class schrodinger.application.matsci.parserutils.StoreDictKeyPair(option_strings, dest, nargs=None, const=None, default=None, type=None, choices=None, required=False, help=None, metavar=None)¶

Bases: argparse._StoreAction

This is the action used with nargs=”+” and values=’KEYWORD=VALUE KEYWORD=VALUE’

By default nargs=”+” and action=’store’ save the multiple values “k1=v1 k2=v2” as list. With this StoreDictKeyPair as the action, “k1=v1 k2=v2” will be stored as {k1:v1, k2:v2} in the options.

__init__(option_strings, dest, nargs=None, const=None, default=None, type=None, choices=None, required=False, help=None, metavar=None)¶

schrodinger.application.matsci.parserutils.type_keywords_to_dict(value)¶

Convert a string of ‘keyword=value keyword=value …’ to a dictionary keyed by keyword. Values are the keyword values.

Note

When calling parser.add_argument for the flag that uses this function, do not use “nargs=+”. That will result in the return value from this function being placed as an item in a list. Instead, do not use nargs at all and simply use “action=’store’”. All of the keyword=value pairs will then be passed into this function as a single string. Example:

parser.add_argument(
    FLAG_KEYWORDS,
    action='store',
    metavar='KEYWORD=VALUE KEYWORD=VALUE ...',
    type=parserutils.type_keywords_to_dict,
    help='Jaguar keywords given as a space-separated keyword=value '
         ' pairs'
)

will result in options.keyword = the dictionary returned by this function

Parameters: value (str) – The argument to validate
Return type: dict
Returns: A dictionary with keywords as key keyword values as values
Raises: argparse.ArgumentTypeError – If the argument is not a valid keyword string

schrodinger.application.matsci.parserutils.type_keywords_to_string(value)¶

Validate the format of a string of ‘keyword=value keyword=value …’

Note

When calling parser.add_argument for the flag that uses this function, do not use “nargs=+”. That will result in the return value from this function being placed as an item in a list. Instead, do not use nargs at all and simply use “action=’store’”. All of the keyword=value pairs will then be passed into this function as a single string. Example:

parser.add_argument(
    FLAG_KEYWORDS,
    action='store',
    metavar='KEYWORD=VALUE KEYWORD=VALUE ...',
    type=parserutils.type_keywords_to_string,
    help='Jaguar keywords given as a space-separated keyword=value '
         ' pairs'
)
