org-mode section numbers (when exported to html) by default starts count from 1, however it is traditional in computer science to start counting from zero. How to make org-mode section numbers start counting from 0 instead of 1?
Plain lists are turned into HTML by the function
org-html-plain-list, which calls
org-html-begin-plain-list outputs the
<ol> tag, and has a provision for outputting a
start attribute as well, but
org-html-plain-list doesn't use it. Interestingly, in the version of
org-mode that I happen to have (which is 6 months old), there's a commented out section of code that looks like someone was thinking about implementing this:
(defun org-html-plain-list (plain-list contents info) "Transcode a PLAIN-LIST element from Org to HTML. CONTENTS is the contents of the list. INFO is a plist holding contextual information." (let* (arg1 ;; (assoc :counter (org-element-map plain-list 'item (type (org-element-property :type plain-list))) (format "%s\n%s%s" (org-html-begin-plain-list type) contents (org-html-end-plain-list type))))
It looks like it would look for a
COUNTER property nearby in the org file. Of course, that would still make you put something in for every single list you used, but it would be a start.
What you could do is use
add-advice to override
org-html-begin-plain-list, so that it always outputs a
start="0" attribute on ordered lists. You might double-check what the latest version of
org-mode does as well; perhaps they've improved it.
