How can you specify alternation (|) in the pattern for #regex? e.g. if you want to match {{ #regex: abcdef | /abc|def/ }} ? Alternatives such as calling #regex twice won't work for me.

Two possible ways:

• Define a Template:! in your wiki which contains nothing move than a |. Then use {{ #regex: abcdef | /abc{{!}}def/ }}.
• Use the regex ascii escaping syntax. Without looking it up, \x7C should work if I am not misstaken. {{ #regex: abcdef | /abc\x7Cdef/ }}.
