      func Handler

      func Handler(args Args) http.HandlerFunc

        Handler creates an HTTP handler that handles go vanity URL requests.

        func IndexHandler

        func IndexHandler(args Args) http.HandlerFunc

          IndexHandler creates a handler to render the index page.

          Note that by default this is already included in Handler so you don't need to use it directly. It's provided, along with Args.NoIndex, so that you could put the index page on a different path.


          type Args

          type Args struct {
          	Config Config
          	// If set to true, do not render and handle the index page.
          	NoIndex bool

            Args defines the args used by Handler function.

            type Config

            type Config struct {
            	// The vanity import prefix shared by all paths, without URL schema and
            	// trailing "/".
            	// Example:
            	// Or:
            	Prefix string `yaml:"prefix" json:"prefix"`
            	// The mappings of the repositories.
            	Mappings []Mapping `yaml:"mappings" json:"mappings"`

              Config defines the configuration used by the http handler.

              type Mapping

              type Mapping struct {
              	// The path of the vanity URL, with leading "/"/
              	// Example:
              	//     /vanity
              	Path string `yaml:"path" json:"path"`
              	// The full URL of the actual repository.
              	// Example:
              	URL string `yaml:"url" json:"url"`
              	// The VCS of the repository. Default to DefaultVCS ("git").
              	VCS VCS `yaml:"vcs" json:"vcs"`
              	// A brief description to be shown on the index page.
              	Description string `yaml:"description" json:"description"`
              	// If set to true, do not show this mapping in index page.
              	HideInIndex bool `yaml:"unlist" json:"unlist"`

                Mapping defines a mapping from a vanity path to an actual repository.

                type PageTmplData

                type PageTmplData struct {
                	// From Config.Prefix.
                	Prefix string
                	// From Config.Mappings
                	Path string
                	URL  string
                	VCS  VCS
                	// The path from the request,
                	// could be different from Path but always have Path as prefix.
                	Reqpath string

                  PageTmplData is the data used to execute PageTmpl.

                  type Templater

                  type Templater interface {
                  	Execute(io.Writer, interface{}) error

                    Templater is the minimal interface shared between go's text and html templates.

                    var IndexTmpl Templater = template.Must(template.New("index").Parse(`<!DOCTYPE html>
                    <title>Vanity go projects for {{.Prefix}}</title>
                    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
                    {{if .Mappings}}
                    {{range $mapping := .Mappings}}
                    {{if $mapping.HideInIndex -}}
                    {{else -}}
                    <li><a href="{{$.Prefix}}{{$mapping.Path}}"><code>{{$.Prefix}}{{$mapping.Path}}</code></a>: (<a href="{{$mapping.URL}}">src</a>)
                    {{- if $mapping.Description -}}
                    {{- end -}}
                    {{- end}}
                    {{- end}}
                    <p>Nothing to see here. Come back later.</p>
                    {{- end}}

                      IndexTmpl is the html template used to render the index page.

                      It's exported so users of this package could replace it to a different one if they so desire.

                      The data used to execute the template is Config.

                      var PageTmpl Templater = template.Must(template.New("vanity").Parse(`<!DOCTYPE html>
                      <title>Vanity page for {{.Prefix}}{{.Reqpath}}</title>
                      ` + MetaTemplateLine + `
                      <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
                      <meta http-equiv="refresh" content="0; url={{.Prefix}}{{.Reqpath}}">
                      Nothing to see here, <a href="{{.Prefix}}{{.Reqpath}}">move along</a>.

                        PageTmpl is the html template used to render the vanity pages.

                        It's exported so users of this package could replace it to a different one if they so desire. But when replacing it, MetaTemplateLine (or equivalent) must exists in the template, or the vanity page might be invalid.

                        The data used to execute the template is defined in PageTmplData.

                        type VCS

                        type VCS string

                          VCS defines the vcs ("git", "mod", "hg", etc.) used in Mapping.

                          It treats zero value (empty string) as DefaultVCS, and behave the same as strings otherwise.

                          const (
                          	DefaultVCS VCS = "git"

                            The default VCS to be used.

                            func (VCS) MarshalText

                            func (v VCS) MarshalText() (text []byte, err error)

                              MarshalText implements encoding.TextMarshaler.

                              func (VCS) String

                              func (v VCS) String() string

                              func (*VCS) UnmarshalText

                              func (v *VCS) UnmarshalText(text []byte) error

                                UnmarshalText implements encoding.TextUnmarshaler.
