Template talk:Evaldemo

This is the talk page for {{Evaldemo}} and {{Evaldemo/3}}

Documentation

For examples see the template pages of evaldemo, evaldemo/3, evdn, and evd.

In theory {{evd}} is designed to replace all, in practice its code is not exactly trivial.

{{evaldemo}} and {{evdn}} support optional substitution.

What gives

The default separator " gives " is kind of annoying if you've seen it too often. It's simple to overwrite the word gives, but not its leading and trailing space:

1. {{evaldemo|whatever|s=separator}},
2. {{evdn|what|ever...|s=separator}},
3. {{evaldemo/3|what|...ever|s=separator}}.

This allows some tricks:

• <small>{{evaldemo|#expr: 1234567890|s=</small>=}} rendered as

  {{#expr: 1234567890}} gives 1234567890 [1]

  Handy to squeeze very long expressions into a single line without folding.

• ;Expression {{evaldemo|#expr: 1234567890|s=gives:}} rendered as

  Expression {{#expr: 1234567890}} gives 1234567890 [2]

  Here semicolon and colon arranged the output as definition list.

• {{evaldemo|#expr: 1234567890|s==<b>}}</b> rendered as

  {{#expr: 1234567890}} gives 1234567890 [3]

  Be bold, <tt>, <b><tt>, <span style="color: red">, or whatever.

• {{evaldemo|#expr: 1/0|s== <font color="red"><em>}}</em></font>

  {{#expr: 1/0}} gives [4]

  Not recommended, but possible for hardcore backwards compatibility.

• {| border="1" cellpadding="5"
  !code!!result
  |-
  |{{evaldemo|#expr: 123456789*10|s=</td><td>}}
  |}

code	result
{{#expr: 123456789*10}} gives 1234567890 [5]

Please note that Wiki markup including template:! (edit•talk•links•history) won't work as separator, use </td><td> to separate table cells as shown above.
