Subject: Optional Arguments
Date: Mon, 7 Dec 2020 04:17:10 +0100 [thread overview]
Message-ID: <trinity-ca649924-eebb-461b-8f6f-fe4cce5648aa-1607311030577@3c-app-mailcom-bs11> (raw)
Would like to have two functions
1. skip-chars - skip to beg of word (if no argument) or end of word (if argument is 1)
2. word-markers - get beg and end of a word position of word
Have written the following. For the first one, I have not used optional arguments before.
And have read documentation about functions.
About the second, there errors when I try to execute.
(defun typh-skip-chars (&optional n)
(interactive "n Skip direction: ")
(if (= n 1)
(skip-chars-forward "[:alpha:]")
(skip-chars-backward "[:alpha:]")) )
(defun typh-word-markers (ma mb)
(interactive)
(skip-chars-backward "[:alpha:]")
(setq ma (point))
(skip-chars-forward "[:alpha:]")
(setq mb (point))
(message "[ma,mb]: %s,%s" ma mb) )
