Find words with alternating vowels and consonants
(Redirected from Find words which odd letters are consonants and even letters are vowels or vice versa)
Find words with alternating vowels and consonants is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
- Task
Using the dictionary unixdict.txt, find words which odd letters are consonants and even letters are vowels or vice versa.
Display the words here (on this page).
The length of any word shown should have a length > 9.

67 words of alternating vowels and consonants found
AppleScript[edit]
Idiomatic[edit]
The handler here is case- and diacritical-insensitive and has an option to treat "y" as a vowel. With the text file located on the computer's startup disk, it performs the set task in just under a third of a second on my machine, which is probably good enough for such a silly task.
(*
With AppleScript's text item delimiters set to all the vowels, the 'text items' of a word with alternating
vowels and consonants are single-character strings (the consonants), with the possibility of an empty
string at the beginning and/or end representing a leading and/or trailing vowel.

Factor[edit]
group-by is used to group words by vowels and consonants. For example, "hello" [ "aeiou" member? ] group-by produces a sequence like { 'h' 'e' 'll' 'o' }. The number of elements in this grouping is the same as the length of the original word if and only if it has alternating vowels and consonants.

$c = qr/[^$vowels]/;

Plain English[edit]
To run:
Start up.
Put "c:\unixdict.txt" into a path.
Read the path into a buffer.
Slap a rider on the buffer.
Loop.
Move the rider (text file rules).
Subtract 1 from the rider's token's last. \remove the newline
Put the rider's token into a word string.
If the word is blank, break.
If the word's length is less than 10, repeat.
If the word is alternating between vowels and consonants, write the word on the console.
Repeat.
Wait for the escape key.
Shut down.
To decide if a string is alternating between vowels and consonants:
Slap a substring on the string.
Put the substring's first plus 1 into the substring's last.
Loop.
If the substring's last's target is noise, say yes.
If the substring is double, say no.
Add 1 to the substring's first.
Add 1 to the substring's last.
Repeat.
To decide if a string is double:
If the string's first's target is any consonant, set a flag.
If the string's last's target is any consonant, set another flag.
If the flag is the other flag, say yes.
Say no.- Output:

Raku[edit]
Sigh. Yet another "Filter a word list" task. In a effort to make it a little more interesting, rather than just doing a one-liner, build a grammar and use that to filter.
grammar VOWCON {
token TOP { <|w> <vowel>? ( <consonant> <vowel> )* <consonant>? <|w> }
token vowel { <[aeiou]> }
token consonant { <[a..z] - [aeiou]> }
}
say ( grep { VOWCON.parse: .lc }, grep { .chars > 9 }, 'unixdict.txt'.IO.words ).batch(6)».fmt('%-15s').join: "\n";
