> they are local tables ... so invisible to users
Fair point. I was concerned more with changeabiltity: this way someone
who writes a new function has an obvious name (numberwords.french) for
her new wordlist, and an obvious single point of alteration for her
copy of verbose.english, namely to change `local words =
numberwords.english` to `...numberwords.french`. (Algorithm tweaks
will still come after that, of course.) The code needs very little
changing. This is a minor point only, of course.
--Sietse
+ local numberwords = { }
- words = {
+ numberwords.english = {
[1] = "one",
...
}
-spanishwords = {
+ numberwords.spanish = {
[1] = "uno",
...
}
function verbose.english(n)
+ local words = allwords.english
... `words` already used throughout ...
end
function verbose.spanish(n)
+ local words = allwords.spanish
-- to use a different table, no need to
-- replace `spanishwords` throughout
-- the function; just change the line above.
... no more `spanishwords`, just `words` ...
end
