As you can see, the template does not behave exactly as its documentation claims it does. I was not sure which to regard as authoritative: the ideal or actual implementation. I ultimately went with the former. Removing and not any from the Lua code will make the module behave like exactly like the template.

Just needs to handle spaces in the params better. -- WOSlinker (talk) 11:41, 2 March 2013 (UTC)

Thanks. Fixed. I moved your test case to the table above. --Ori.livneh (talk) 05:58, 3 March 2013 (UTC)

Yesno has ~8M transclusions. No question it should handle the legacy 1:1. Test it. -DePiep (talk) 22:31, 11 March 2013 (UTC)

The documentation is wrong. The "egg" example assumes thet the input value is blank. But in the code examples the input parameter is omitted. Compare:

• {{yesno|blank= eggs|no=ham}} →
• {{yesno||blank= eggs|no=ham}} → eggs

This is what is actually documented:

• {{yesno|blank= eggs|no=ham|¬=bread}} → bread

Why?

{{yesno}} is quite simple, so I'm not sure if there is a point in replacing it with functionally equivalent Lua. There are many cases where Lua can be much faster and easier to read, but I'm not sure that is the case here. In fact, because of the slight overhead with #invoke, simple parser functions can actually be slightly faster than the equivalent Lua. I haven't tested that here, but I wouldn't be surprised if there is no performance advantage in a case like this. Seems like a strange template to target for Lua conversion.

test failed

One fail found in unit test: value "1= ¬ " (with whitespace). Reason:whitespace not removed before this check. Possible solution; treat '¬' as a character, separate from nil. (if val == nil or val == '¬' then ...). -DePiep (talk) 11:54, 23 March 2013 (UTC)

• Another fail: input value="00". See Module talk:Yesno/testcases. -DePiep (talk) 12:56, 23 March 2013 (UTC)
