What it does

Miln Checkbox matches pairs of square brackets within your Trac wiki pages. The brackets need to brace one of the following characters be matched: ' ' (space), '+', 'x', or 'X'.

Miln Checkbox uses the following regular expression to perform the matching: \[[ xX+]\]

The following wiki formatted list contains four pairs of brackets that will be matched by Miln Checkbox:

 * [ ] space within brackets
 * [x] lowercase x within brackets
 * [X] uppercase X within brackets
 * [+] plus within brackets

When matches are found, the brackets are replaced with checkboxes:

The HTML input checkboxes are disabled to avoid users thinking the elements are interactive and persistent.
