run(def)

errors if init field not in def

assert.raises 'init', -> command_panel\run {}

invokes init on def, passing in def, a CommandLine

local args
def = init: spy.new (arg1, arg2) -> args = {arg1, arg2}
run_in_coroutine -> command_panel\run def
assert.spy(def.init).was_called 1
assert.equal def, args[1]
assert.same 'CommandLine', typeof(args[2])

def = {
  init: spy.new ->
  on_text_changed: spy.new ->
}
run_in_coroutine -> command_panel\run def
assert.spy(def.on_text_changed).was_called_with def, ''

def = {
  init: spy.new ->
  on_text_changed: spy.new ->
}
run_in_coroutine -> command_panel\run def, text: 'initial'
assert.spy(def.on_text_changed).was_called_with def, 'initial'

(cancel)

cancels running command lines

result = '<unset>'
run_in_coroutine -> result = command_panel\run {init: ->}
command_panel\cancel!
assert.is_nil result

invokes on_close

def = {
  init: spy.new ->
  on_close: spy.new ->
}
run_in_coroutine -> command_panel\run def
command_panel\cancel!
assert.spy(def.on_close).was_called 1

CommandLine

local command_line, text_widget, def
result = '<unset>'

before_each ->
  def = {
    init: (_, c) ->
      command_line = c
      text_widget = c.command_widget
  }
  run_in_coroutine -> result = command_panel\run def

finish(result) terminates the invocation, returning result

command_line\finish 'result'
assert.same 'result', result

finishing calls on_close

def.on_close = spy.new ->
command_line\finish 'result'
assert.spy(def.on_close).was_called 1

.prompt and .text set the text in the text widget

command_line.prompt = 'prompt>'
assert.same 'prompt>', text_widget.text
command_line.text = 'hello'
assert.same 'prompt>hello', text_widget.text

command_line.prompt = '[bye]'
command_line.text = 'hello'
assert.same '[bye]hello', text_widget.text
command_line.text = ''
assert.same '[bye]', text_widget.text

add_widget calls to_gobject and show on the added widget

widget = {
  to_gobject: spy.new -> Gtk.Box!
  show: spy.new ->
}
command_line\add_widget 'name', widget
assert.spy(widget.to_gobject).was_called 1
assert.spy(widget.show).was_called 1

changing the text invokes def.on_text_changed

def.on_text_changed = spy.new ->
command_line.text = 'changed'
assert.spy(def.on_text_changed).was_called 1
assert.spy(def.on_text_changed).was_called_with def, 'changed'

local def2, command_line2
before_each ->
  def2 = {
  init: spy.new (_, c) ->
    command_line2 = c
  }
  run_in_coroutine -> result = command_panel\run def2

assert.spy(def2.init).was_called 1

assert.is_true command_line.is_hidden
assert.is_false command_line2.is_hidden

assert.is_true command_line.is_open
assert.is_true command_line2.is_open

def.on_text_changed = spy.new ->

command_line2.text = 'changed'
assert.spy(def2.on_text_changed).was_called 1
assert.spy(def2.on_text_changed).was_called_with def2, 'changed'
assert.spy(def.on_text_changed).was_not_called!
