Essentially {{str/len}}, but counts the number of times {{{1}}} appears in {{{2}}}.

Note that {{{1}}} can be any regular expression.

Examples

{{str/count|a|abca}}

→ 2

{{str/count|\d|abc 123}}

→ 3

{{str/count|\D|abc 123}}

→ 4

{{str/count|\w+|this is an example}}

→ 4 (\w+ matches one or more "word" characters, but not spaces)

  {{str/count|\[\[[^]]+\]\]|This is text with a [[link]] and [[another link]].}}

→ 2

Breakdown of regular expression:

Section	Meaning	Explanation
\[\[	[[	Two literal [ characters (note that [ and ] have a special meaning in regular expressions).
[^]]	Any character that is not ]	A character class -- matches all characters listed between the brackets. The ^ is the negation operator, causing all characters not listed to be matched instead. In this case, the first ] is the only character matched, since the second is the closing bracket. The first bracket is not treated as the closing bracket, since an empty character class is invalid.
+	Allows one or more matches of the previous expression	(in this case, it allows the non-] characters to be repeated)
\]\]	]]	Matches two literal ] characters.
