This code fragment is suitable to drop into DrChip's CStubs from script#1269.
If you have ever wanted to match parts of a word you may have considered something like:
if wrd == "re" || wrd == "ret" || wrd == "retu" || wrd == "retur" "do something
Although the above works well enough it is a pain to maintain and add new words (not to mention it's just a touch messy).
A more elegant (and easier to use I believe) method would be to use \%[] as part of a pattern.
For instance, "\\<re\\%[tur]\\>" will match "re", "ret", "retu" or "retur"
Explanation:
\\< = start of word re = first letters of word we want to require to match \\%[tur] = optionally match chars between the braces, i.e. 't', 'tu' or 'tur' \\> = end of word
So, we can use this as a pattern for match like so (in DrChip's CStubs):
elseif match(wrd, "\\<re\\%[tur]\\>") > -1 exe "norm! bdWireturn\<Esc>"
Which, I think, is a little better than the longer alternative:
" vs elseif wrd == "re" || wrd == "ret" || wrd == "retu" || wrd == "retur" exe "norm! bdWireturn\<Esc>"
