boolean options don't seem to work

[tmbdev]

Boolean options don't seem to work the way they should. Here is an example:

package main

import (
    "fmt"
    "github.com/docopt/docopt-go"
)

var usage string = `
Mytest.

Usage:
    mytest [options]

Options:
  --flag    a flag
`

func main() {
    opts, _ := docopt.ParseDoc(usage)
    flag, err := opts.Bool("--flag")
    fmt.Println(flag)
    fmt.Println(err)
}

$ go run mytest.go
false
key: "--flag" failed type conversion
$ go run mytest.go --flag
--flag requires argument
Usage:
    mytest [options]
exit status 1
$ go run mytest.go --flag=true
false
key: "--flag" failed type conversion
$ go version
go version go1.14.1 linux/amd64
$

You are using a tab between --flag and a. The docopt website says:

Use two spaces to separate options with their informal description.

If you replace the tab with two (or more) spaces, it works:

package main

import (
        "fmt"
        "github.com/docopt/docopt-go"
)

var usage string = `
Mytest.

Usage:
        mytest [options]

Options:
  --flag    a flag
`

func main() {
        opts, _ := docopt.ParseDoc(usage)
        flag, err := opts.Bool("--flag")
        fmt.Println(flag)
        fmt.Println(err)
}

$ go run mytest.go
false
<nil>
$ go run mytest.go --flag
true
<nil>

@tmbdev it looks like that this ticket can be closed?

Wouldn't it make sense to permit tabs?

@tmbdev I am just an observer, so take my answer for what is worth. Permitting tabs would require to reach consensus on all the docopt project, not only docopt.go. The whole project itself seems to be inactive (see #74) This ticket is solved: just use spaces :-)
