Own parameter

[weatherc]

Are there a way to "send" an own parameter to tessera?
In my case do i run weathermaps with multiple layers of same variable with different hour-number, like temperature_2. So i'm looking for a way to have only one definition for temperature in the config file instead of needing to define it say 72 times where the only difference would be only that hour-number (and same for all other variables).
Something like:

"/temperature":{
"source": "mapnik:///home/node/temperature_{{hour}}.xml",
"cors": true
}

In Leaflet could it then be setup like:
/tilelive/temperature/2/{z}/{x}/{y}.png

That's a great idea. My first instinct would be to implement a custom (but very simple) tilelive module to handle the dynamic configuration files, but there's no way to handle prefixes (the hour number). My second would be to build a custom tile server similar to either https://github.com/stamen/sm2 or https://github.com/fieldpapers/fp-tiler.

However, this is straightforward and flexible enough that I think it does belong in core.

Slightly refined proposed syntax (so it's clear where hour could come from):

"/temperature/:hour": {
  "source": "mapnik:///home/node/temperature_{{hour}}.xml",
  "cors": true
}

That sounds great. The refined syntax looks just fine.
