Another random mod by me.
This mod provides a "Wiki" block. You can create and edit wiki pages with it.
The pages are saved as <worldpath>/wiki/<pagename>. All spaces in the page
name are converted to underscores, and all other characters not in
[A-Za-z0-9-] are converted to hex notation %XX.
The text can contain hyperlinks in the form of [link text] to other pages.
Such links are added at the right of the form.
You can craft a "Wiki block" by putting 9 bookshelves in the crafting grid.
Only players with the wiki priv can create/edit pages.
Install by following the instructions in the Installing mods
article on the Minetest wiki, then add wiki to the secure.trusted_mods
setting in minetest.conf.
