Command godocdown generates Go documentation in a GitHub-friendly Markdown
format.
$ go get github.com/robertkrimen/godocdown/godocdown
$ godocdown /path/to/package > README.markdown
# Generate documentation for the package/command in the current directory
$ godocdown > README.markdown
# Generate standard Markdown
$ godocdown -plain .
This program is targeted at providing nice-looking documentation for GitHub.
With this in mind, it generates GitHub Flavored Markdown
(http://github.github.com/github-flavored-markdown/) by default. This can be
changed with the use of the "plain" flag to generate standard Markdown.
Install
go get github.com/robertkrimen/godocdown/godocdown
Example
http://github.com/robertkrimen/godocdown/blob/master/example.markdown
Usage

-template=""
The template file to use
-no-template=false
Disable template processing
-plain=false
Emit standard Markdown, rather than Github Flavored Markdown
-heading="TitleCase1Word"
Heading detection method: 1Word, TitleCase, Title, TitleCase1Word, ""
For each line of the package declaration, godocdown attempts to detect if
a heading is present via a pattern match. If a heading is detected,
it prefixes the line with a Markdown heading indicator (typically "###").
1Word: Only a single word on the entire line
[A-Za-z0-9_-]+
TitleCase: A line where each word has the first letter capitalized
([A-Z][A-Za-z0-9_-]\s*)+
Title: A line without punctuation (e.g. a period at the end)
([A-Za-z0-9_-]\s*)+
TitleCase1Word: The line matches either the TitleCase or 1Word pattern
Templating
In addition to Markdown rendering, godocdown provides templating via
text/template (http://golang.org/pkg/text/template/) for further customization.
By putting a file named ".godocdown.template" (or one from the list below) in
the same directory as your package/command, godocdown will know to use the file
as a template.
# text/template
.godocdown.markdown
.godocdown.md
.godocdown.template
.godocdown.tmpl
A template file can also be specified with the "-template" parameter
Along with the standard template functionality, the starting data argument has
the following interface:
{{ .Emit }}
// Emit the standard documentation (what godocdown would emit without a template)
{{ .EmitHeader }}
// Emit the package name and an import line (if one is present/needed)
{{ .EmitSynopsis }}
// Emit the package declaration
{{ .EmitUsage }}
// Emit package usage, which includes a constants section, a variables section,
// a functions section, and a types section. In addition, each type may have its own constant,
// variable, and/or function/method listing.
{{ if .IsCommand }} ... {{ end }}
// A boolean indicating whether the given package is a command or a plain package
{{ .Name }}
// The name of the package/command (string)
{{ .ImportPath }}
// The import path for the package (string)
// (This field will be the empty string if godocdown is unable to guess it)
