urlp

URL pattern match

Install

go get gopkg.in/nowk/urlp.v1

Examples

v, ok := urlp.Match("/posts/:post_id/comments/:id", "/posts/123/comments/456")
if !ok {
  // handle
}

post_id := v.Get(":post_id")
id := v.Get(":id")

.:format

Adding .:format at the end of the pattern returns a special named param :_format which returns the given format.

v, ok := urlp.Match("/posts/:id.:format", "/posts/123.json")
if !ok {
  // handle
}

id := v.Get(":id")
format := v.Get(":_format")

With a .:format set the pattern will match paths with or without the extension.

v, ok := urlp.Match("/posts/:id.:format", "/posts/123.json")
// ok       => true
// :_format => "json"

v, ok := urlp.Match("/posts/:id.:format", "/posts/123")
// ok       => true
// :_format => ""

.:format must be at the end of the pattern, else it will be treated as any other named parameter.

Without .:format paths with a .ext will not be matched
