Playground for creating dynamic content on MediaWiki 1.34+
Programmatically generated static output for wiki pages in written in LUA. The Lua script resides in a Wiki Module, and functions can be called with #invoke:
- Fahrenheit to Celsius
- 0 °F is -17.8 °C
- 10 °F is -12.2 °C
- 20 °F is -6.7 °C
- 30 °F is -1.1 °C
- 40 °F is 4.4 °C
- 50 °F is 10.0 °C
- 60 °F is 15.6 °C
- 70 °F is 21.1 °C
- 80 °F is 26.7 °C
- 90 °F is 32.2 °C
- 100 °F is 37.8 °C
- Celsius to Fahrenheit
- 0 °C is 32.0 °F
- 10 °C is 50.0 °F
- 20 °C is 68.0 °F
- 30 °C is 86.0 °F
- 40 °C is 104.0 °F
- 50 °C is 122.0 °F
- 60 °C is 140.0 °F
- 70 °C is 158.0 °F
- 80 °C is 176.0 °F
- 90 °C is 194.0 °F
- 100 °C is 212.0 °F
Truely dynamic and interactive content can be created with the Graph extension. "Graphs" are programmed in VEGA2
