Filetypes duplicates when you set filetype

[dustdfg]

Description of the problem or steps to reproduce

TL;DR it is not a problem of the filetype but almost about reloading and solvable by #3062

When I use set filetype <filetype> the auto-completion duplicate names

1. Open micro
2. Write set filetype
3. Press tab
4. Press enter
5. Write again set filetype
6. Press tab again

Roots of the problem

Firstly I thought problem in

micro/internal/action/infocomplete.go

Lines 62 to 96 in 5ae2799

	func colorschemeComplete(input string) (string, []string) {
	var suggestions []string
	files := config.ListRuntimeFiles(config.RTColorscheme)
	for _, f := range files {
	if strings.HasPrefix(f.Name(), input) {
	suggestions = append(suggestions, f.Name())
	}
	}
	var chosen string
	if len(suggestions) == 1 {
	chosen = suggestions[0]
	}
	return chosen, suggestions
	}
	// filetypeComplete autocompletes filetype
	func filetypeComplete(input string) (string, []string) {
	var suggestions []string
	for _, f := range config.ListRuntimeFiles(config.RTSyntax) {
	if strings.HasPrefix(f.Name(), input) {
	suggestions = append(suggestions, f.Name())
	}
	}
	var chosen string
	if len(suggestions) == 1 {
	chosen = suggestions[0]
	}
	return chosen, suggestions
	}

But then I realized that code for color schemes auto-completion is the same as for filetype auto-completion.

micro/internal/action/infocomplete.go

Lines 190 to 194 in 5ae2799

	switch inputOpt {
	case "colorscheme":
	_, suggestions = colorschemeComplete(input)
	case "filetype":
	_, suggestions = filetypeComplete(input)

They even used both in the same way so the problem not in the action/infocomplete.go

The problem is somewhere inside the buffer.SetOption function which tries to make reload

micro/internal/buffer/settings.go

Lines 22 to 33 in 5ae2799

	} else if option == "filetype" {
	config.InitRuntimeFiles()
	err := config.ReadSettings()
	if err != nil {
	screen.TermMessage(err)
	}
	err = config.InitGlobalSettings()
	if err != nil {
	screen.TermMessage(err)
	}
	config.InitLocalSettings(b.Settings, b.Path)
	b.UpdateRules()
