Character Finder Utility

5+
Usage tips
6+
==========
7+
8+
`cf.py` works as an executable on Unix-like systems,
9+
if you have `python3` on your `$PATH`::
10+
11+
$ chmod +x cf.py
12+
$ ./cf.py cat eyes
13+
U+1F638 😸 GRINNING CAT FACE WITH SMILING EYES
14+
U+1F63B 😻 SMILING CAT FACE WITH HEART-SHAPED EYES
15+
U+1F63D 😽 KISSING CAT FACE WITH CLOSED EYES
16+
17+
Use `wc -l` to count the number of hits::
18+
19+
$ ./cf.py hieroglyph | wc -l
20+
1663
21+
22+
With `tee` you can get the output and the count::
23+
24+
$ ./cf.py trigram | tee >(wc -l)
25+
U+2630 ☰ TRIGRAM FOR HEAVEN
26+
U+2631 ☱ TRIGRAM FOR LAKE
27+
U+2632 ☲ TRIGRAM FOR FIRE
28+
U+2633 ☳ TRIGRAM FOR THUNDER
29+
U+2634 ☴ TRIGRAM FOR WIND
30+
U+2635 ☵ TRIGRAM FOR WATER
31+
U+2636 ☶ TRIGRAM FOR MOUNTAIN
32+
U+2637 ☷ TRIGRAM FOR EARTH

36+
Running the tests
37+
=================
38+
39+
Run the ``doctest`` module from the command line on
40+
this README.rst file (using ``-v`` to make tests visible)::
41+
42+
$ python3 -m doctest README.rst -v
43+
44+
That's what the ``test.sh`` script does.
45+
46+
47+
Tests
48+
-----
49+
50+
Import functions for testing::
51+
52+
>>> from cf import find, main
53+
54+
Test ``find`` with single result::
55+
56+
>>> find('sign', 'registered') # doctest:+NORMALIZE_WHITESPACE
57+
U+00AE ® REGISTERED SIGN
58+
59+
Test ``find`` with two results::
60+
61+
>>> find('chess', 'queen', last=0xFFFF) # doctest:+NORMALIZE_WHITESPACE
62+
U+2655 ♕ WHITE CHESS QUEEN
63+
U+265B ♛ BLACK CHESS QUEEN
64+
65+
Test ``find`` with no results::
66+
67+
>>> find('no_such_character')
68+
69+
Test ``main`` with no words::
70+
71+
>>> main([])
72+
Please provide words to find.
