mango

Generate manual pages from the source code of your Go commands

mango is a small command line utility that allows you to create manual pages from the source code of your Go commands. It builds manual pages from the comments and flag function calls found in your .go files.

Building

Execute

go get github.com/slyrz/mango
go build github.com/slyrz/mango

to build mango.

Running

Pass one or more .go files as command line arguments to mango. mango treats them as a list of independent Go commands and creates a manual page for each argument.

mango file1.go file2.go ...

Usage

Source File

// example - shows the basic usage of mango
//
// Description:
//
// It doesn't take much to create manual pages with mango. Just write down
// stuff you want to include in the manual page in a comment at the top
// of your source file like this. Feel free to add as many sections as you
// want.
package main

import (
    "flag"
)

var (
    optFoo = flag.Bool("foo", false, "This text should show up in the manual page.")

    // If the flag declaration follows a comment like this, mango displays the
    // comment as description in the manual page.
    optBar = flag.Bool("bar", false, "The above comment should show up in the manual page.")
    optBaz = ""
)

func init() {
    // These two calls reference the same variable and will appear
    // grouped in the manual page. Since these aren't boolean flags, mango
    // prints the argument type as well.
    flag.StringVar(&optBaz, "baz", "", "Two calls, but one entry in the manual.")
    flag.StringVar(&optBaz, "b", "", "Two calls, but one entry in the manual.")
}

func main() {
    return
}
