SlashedQueryUrls

This is a stable-version but not well-tested.

A simple function to generate paths compatible with gorilla-mux(http://www.gorillatoolkit.org/pkg/mux) from a simple pattern.

The Package

There are just one exported function

func GetUrlVarsPermutations(baseUrl string, isLong bool) []string

• If isLong is false, the baseUrl must attend a pattern:
  • ^(/[^{}/ ]+)(/{[^{}/ ]+}[?]?)$
• If isLong is false, the baseUrl must attend a pattern:
  • ^(/[^{}/ ]+)((/[^{}/ ]+)/{[^{}/ ]+}[?]?)$

non-long example:

paths := muxUrlGen.GetUrlVarsPermutations("/img/{type}/{length}?/{width}?", false)
fmt.Println(paths) 
/* Output:
/img/type/{type}
/img/type/{type}/width/{width}
/img/type/{type}/height/{height}
/img/width/{width}/type/{type}
/img/height/{height}/type/{type}
/img/type/{type}/width/{width}/height/{height}
/img/type/{type}/height/{height}/width/{width}
/img/width/{width}/height/{height}/type/{type}
/img/width/{width}/type/{type/height/{height}
/img/height/{height}/width/{width}/type/{type}
/img/height/{height}/type/{type}/width/{width}
*/

The motivation

You could want route several paths to the same handler

• /address/street/{street}/number/{number:[0-9]+}/city/{city}
• /address/street/{street}/city/{city}/number/{number:[0-9]+}
• /address/number/{number:[0-9]+}/street/city/{city}/{street}
• /address/number/{number:[0-9]+}/street/{street}/city/{city}
• /address/city/{city}/street/{street}/number/{number:[0-9]+}
• /address/city/{city}/number/{number:[0-9]+}/street/{street}
• /address/city/{city}/street/{street}
• /address/street/{street}/city/{city}

There aren't a concise way to do that with gorilla-mux. I made that package to generate permutations on a url
