How to install

devtools::install_github("idmn/wfindr")

How to use

Describe a pattern that a word should match by marking unknown letters.

• Unknown letter is denoted by dot ".".
• Dot may be followed by regex {...} repetition quantifier. Namely, .{n} means exactly n unknown letters, .{n,} - n or more, .{n, m} - from n to m.
• Asterisk * denotes unknown number of unknown letters.

Then pass this pattern to a find_word function. Examples:

#> words starting with "aa"
find_word("aa*")
#> 4-letter words stating with "w" and ending with "d"
find_word("w..d")
#> 30 or more letter words
find_word(".{30,}")

You can also specify letters that you don't want to be used to fill the gaps with ban argument.

find_word("w..d", ban = "oe")

Or you can determine the list of letters to be used with allow argument.

find_word("w..d", allow = "oe")

Scrabble solver

To find words that can be constructed from the specified set of letters, use scrabble function

#> words constructed from the "thing" word's letters
scrabble("thing")

This function is actually built on top of the find_word function. To give you an idea, the previous call is equivalent to this:

find_word(allow = "thing", type = "scrabble")

It is also possible to specify a pattern in scrabble, as it was in find_word. For, example, to get at least 4-letter words:

scrabble("thing", ".{4,}")

Anagram solver

To find anagrams, use anagram function.

anagram("thing")

This function is also built on top of find_word and the previous call is equivalent to

find_word(allow = "thing", type = "anagram")
