-# Generating Man Pages For Your Own cobra.Command

-Generating man pages from a cobra command is incredibly easy. An example is as follows:
-
-```go
-package main
-
-import (
-	"log"
-
-	"github.com/spf13/cobra"
-	"github.com/spf13/cobra/doc"
-)
-
-func main() {

-		Section: "3",
-	}
-	err := doc.GenManTree(cmd, header, "/tmp")
-	if err != nil {
-		log.Fatal(err)
-	}
-}
-```
-
-That will get you a man page `/tmp/test.3`

-# Generating Markdown Docs For Your Own cobra.Command
-
-Generating man pages from a cobra command is incredibly easy. An example is as follows:
-
-```go
-package main
-
-import (
-	"log"
-
-	"github.com/spf13/cobra"
-	"github.com/spf13/cobra/doc"
-)
-
-func main() {
-	cmd := &cobra.Command{
-		Use:   "test",
-		Short: "my test program",
-	}
-	err := doc.GenMarkdownTree(cmd, "/tmp")
-	if err != nil {
-		log.Fatal(err)
-	}
-}
-```
-
-That will get you a Markdown document `/tmp/test.md`
-
-## Generate markdown docs for the entire command tree
-
-This program can actually generate docs for the kubectl command in the kubernetes project
-
-```go
-package main
-
-import (
-	"log"
-	"io/ioutil"
-	"os"
-
-	"k8s.io/kubernetes/pkg/kubectl/cmd"
-	cmdutil "k8s.io/kubernetes/pkg/kubectl/cmd/util"
-
-	"github.com/spf13/cobra/doc"
-)
-
-func main() {
-	kubectl := cmd.NewKubectlCommand(cmdutil.NewFactory(nil), os.Stdin, ioutil.Discard, ioutil.Discard)
-	err := doc.GenMarkdownTree(kubectl, "./")
-	if err != nil {
-		log.Fatal(err)
-	}
-}
-```
-
-This will generate a whole series of files, one for each command in the tree, in the directory specified (in this case "./")
-
-## Generate markdown docs for a single command
-
-You may wish to have more control over the output, or only generate for a single command, instead of the entire command tree. If this is the case you may prefer to `GenMarkdown` instead of `GenMarkdownTree`
-
-```go
-	out := new(bytes.Buffer)
-	err := doc.GenMarkdown(cmd, out)
-	if err != nil {
-		log.Fatal(err)
-	}
-```
-
-This will write the markdown doc for ONLY "cmd" into the out, buffer.
-
-## Customize the output
-
-Both `GenMarkdown` and `GenMarkdownTree` have alternate versions with callbacks to get some control of the output:
-
-```go
-func GenMarkdownTreeCustom(cmd *Command, dir string, filePrepender, linkHandler func(string) string) error {
-	//...
-}
-```
-
-```go
-func GenMarkdownCustom(cmd *Command, out *bytes.Buffer, linkHandler func(string) string) error {
-	//...
-}
-```
-
-The `filePrepender` will prepend the return value given the full filepath to the rendered Markdown file. A common use case is to add front matter to use the generated documentation with [Hugo](http://gohugo.io/):
-
-```go
-const fmTemplate = `---
-date: %s
-title: "%s"
-slug: %s
-url: %s
----
-`
-
-filePrepender := func(filename string) string {
-	now := time.Now().Format(time.RFC3339)
-	name := filepath.Base(filename)
-	base := strings.TrimSuffix(name, path.Ext(name))
-	url := "/commands/" + strings.ToLower(base) + "/"
-	return fmt.Sprintf(fmTemplate, now, strings.Replace(base, "_", " ", -1), base, url)
-}
-```
-
-The `linkHandler` can be used to customize the rendered internal links to the commands, given a filename:
-
-```go
-linkHandler := func(name string) string {
-	base := strings.TrimSuffix(name, path.Ext(name))
-	return "/commands/" + strings.ToLower(base) + "/"
-}
-```

-# Generating ReStructured Text Docs For Your Own cobra.Command
-
-Generating ReST pages from a cobra command is incredibly easy. An example is as follows:
-
-```go
-package main
-
-import (
-	"log"
-
-	"github.com/spf13/cobra"
-	"github.com/spf13/cobra/doc"
-)
-
-func main() {
-	cmd := &cobra.Command{
-		Use:   "test",
-		Short: "my test program",
-	}
-	err := doc.GenReSTTree(cmd, "/tmp")
-	if err != nil {
-		log.Fatal(err)
-	}
-}
-```
-
-That will get you a ReST document `/tmp/test.rst`
-
-## Generate ReST docs for the entire command tree
-
-This program can actually generate docs for the kubectl command in the kubernetes project
-
-```go
-package main
-
-import (
-	"log"
-	"io/ioutil"
-	"os"
-
-	"k8s.io/kubernetes/pkg/kubectl/cmd"
-	cmdutil "k8s.io/kubernetes/pkg/kubectl/cmd/util"
-
-	"github.com/spf13/cobra/doc"
-)
-
-func main() {
-	kubectl := cmd.NewKubectlCommand(cmdutil.NewFactory(nil), os.Stdin, ioutil.Discard, ioutil.Discard)
-	err := doc.GenReSTTree(kubectl, "./")
-	if err != nil {
-		log.Fatal(err)
-	}
-}
-```
-
-This will generate a whole series of files, one for each command in the tree, in the directory specified (in this case "./")
-
-## Generate ReST docs for a single command
-
-You may wish to have more control over the output, or only generate for a single command, instead of the entire command tree. If this is the case you may prefer to `GenReST` instead of `GenReSTTree`
-
-```go
-	out := new(bytes.Buffer)
-	err := doc.GenReST(cmd, out)
-	if err != nil {
-		log.Fatal(err)
-	}
-```
-
-This will write the ReST doc for ONLY "cmd" into the out, buffer.
-
-## Customize the output
-
-Both `GenReST` and `GenReSTTree` have alternate versions with callbacks to get some control of the output:
-
-```go
-func GenReSTTreeCustom(cmd *Command, dir string, filePrepender func(string) string, linkHandler func(string, string) string) error {
-	//...
-}
-```
-
-```go
-func GenReSTCustom(cmd *Command, out *bytes.Buffer, linkHandler func(string, string) string) error {
-	//...
-}
-```
-
-The `filePrepender` will prepend the return value given the full filepath to the rendered ReST file. A common use case is to add front matter to use the generated documentation with [Hugo](http://gohugo.io/):
-
-```go
-const fmTemplate = `---
-date: %s
-title: "%s"
-slug: %s
-url: %s
----
-`
-filePrepender := func(filename string) string {
-	now := time.Now().Format(time.RFC3339)
-	name := filepath.Base(filename)
-	base := strings.TrimSuffix(name, path.Ext(name))
-	url := "/commands/" + strings.ToLower(base) + "/"
-	return fmt.Sprintf(fmTemplate, now, strings.Replace(base, "_", " ", -1), base, url)
-}
-```
-
-The `linkHandler` can be used to customize the rendered links to the commands, given a command name and reference. This is useful while converting rst to html or while generating documentation with tools like Sphinx where `:ref:` is used:
-
-```go
-// Sphinx cross-referencing format
-linkHandler := func(name, ref string) string {
-    return fmt.Sprintf(":ref:`%s <%s>`", name, ref)
-}
-```
