🐜 abbrev: Expand abbreviations 🐜

Expand a Sequence or Mapping of string abbreviations.

Handy when the user has a choice of commands with long names.

Example 1: Use a list of choices

import abbrev

a = ['one', 'two', 'three']

assert abbrev(a, 'one') == 'one'
assert abbrev(a, 'o') == 'one'
assert abbrev(a, 'tw') == 'two'

abbrev(a, 'four')  # Raises a KeyError: no such key
abbrev(a, 't')  # Raises a KeyError: ambiguous key ('two' or 'three'?)

Example 2: Use a dictionary of choices

import abbrev

d = {'one': 100, 'two': 200, 'three': 300}

assert abbrev(d, 'one') == 100
assert abbrev(d, 'o') == 100
assert abbrev(d, 'tw') == 200

Example 3: Make an abbreviator to re-use

import abbrev

d = {'one': 100, 'two': 200, 'three': 300}

abbreviator = abbrev(d)

assert abbreviator('one') == my_abbrevs('o') == 100
assert abbreviator('tw') == 200

Example 4: Get all matches, when multi=True

import abbrev

a = ['one', 'two, 'three'}

multi = abbrev(a, multi=True)  # Make an abbreviator

assert multi('t') == abbrev(d, 't', multi=True) == ('two', three')
assert multi('o') == abbrev(d, 'o', multi=True) == ('one', )

multi('four')  # Still raises a key error

Example 5: Get only the first result, when unique=False

import abbrev

d = {'one': 100, 'two': 200, 'three': 300}

assert abbrev(d, 't', unique=False) == (200, 300)
