Template:Par2b

   (default none)

---

Variant of Template:Par2 for testing;

Would like to use conditional test for presence of argument {{{3}}}:
{{#if:{{{3|}}}| (default '''{{{3}}}''')|}}

DOES NOT WORK due to lack of mediawiki Extension:ParserFunctions

• Even if extension were installed, would not work if default is ' ' (space) ...which they are on many, many pages.

...intended sample output:

Foo(clip [, float gain_y] [, int size] [, boolean autogain] [, string file])

clip (default none)

Input clip

int  size (default 24)

Cras in mauris ac eros mollis pellentesque non non metus. Proin vitae mauris tempor, tristique sem vitae, suscipit ante.
