User:Misza13/Random

This template is an attempt at creating a "random number generator" using WikiSyntax. It generates pseudorandom numbers that change whenever a page containing it is edited or every minute (the latter update may require purging the page's cache).

Usage:

{{{{NAMESPACE}}:{{PAGENAME}}}} produces a random decimal digit: {{{{NAMESPACE}}:{{PAGENAME}}}}
{{{{NAMESPACE}}:{{PAGENAME}}|N|M}} produces a random number from M to M+N-1, i.e. it rolls a 1dN+M-1, where the M, if ommited, is set to 0. (As you might've guessed by now, N defaults to 10.) Example: {{{{NAMESPACE}}:{{PAGENAME}}|90|10}} generates a two-digit number: {{{{NAMESPACE}}:{{PAGENAME}}|90|10}}

You can (or rather should!) also specify up to 6 seeds for the generator, which (I think) should be different prime numbers:

{{{{NAMESPACE}}:{{PAGENAME}}|seed1=7|seed2=47}} gives {{{{NAMESPACE}}:{{PAGENAME}}|seed1=47|seed2=7}}
{{{{NAMESPACE}}:{{PAGENAME}}|seed2=11|seed5=59|seed6=3}} gives {{{{NAMESPACE}}:{{PAGENAME}}|seed2=11|seed5=59|seed6=3}}

Notes:

This template does not render properly when previewing a page. This is because the {{REVISIONID}} variable (one of the sources of "randomness") is not set on preview. It will show up after saving, though.
The seed parameters should not be set to high values to avoid integer overflow. You'll know something's wrong when the generator produces negative numbers while it shouldn't.
