I've been using this regular expression to pull out mustached {{Hello}} content:
/{{\s*[\w\.]+\s*}}/g
It's falling down when the mustached string contains square brackets. I've been fiddling with it for ages to no avail, could anyone suggest an adjustment that will mean it will match {{Hello[0]}} ?
I'm your Huckleberry:
\{\{(.*?)\}\}
I always hack around with these using the excellent http://www.regexr.com/
So, to explain why this works for this situation:
\\{\\{
– we escape (by 'escaping' with a backslash the next character doesn't get evaluated by the expression, eg it just looks for that character) the first character we are looking for (the curly brace). (
to make a 'group' to capture multiple tokens – so we can grab everything inside the braces. .
matches any characters except line breaks. *
matches zero or more of the preceding token (in this case any token except line breaks) ?
makes the previous quantifier 'lazy' in that it will match as few as possible. )
. \\}\\}
