蜻蜓的模态命令

Modal commands with Dragonfly

我正在使用 dragonfly2,我想创建一个像 vim 一样的模态语法。我希望能够使用命令启用和禁用语法。

例如,如果我说 link,我有一个操作会在屏幕上显示带有 2 个字母标签的可能链接列表,所以我希望语法启用只接受 2-信的话。特别是,在说 link 之后,我不希望语​​法像另一个 link.

一样接受任何普通命令

这可能吗?

啊哈!我刚在 someone else's grammar 中找到这个:

class PythonEnabler(CompoundRule):
    spec = "Enable Python"                  # Spoken command to enable the Python grammar.

    def _process_recognition(self, node, extras):   # Callback when command is spoken.
        pythonBootstrap.disable()
        pythonGrammar.enable()
        print "Python grammar enabled"

class PythonDisabler(CompoundRule):
    spec = "switch language"                  # spoken command to disable the Python grammar.

    def _process_recognition(self, node, extras):   # Callback when command is spoken.
        pythonGrammar.disable()
        pythonBootstrap.enable()
        print "Python grammar disabled"

pythonBootstrap = Grammar("python bootstrap")                
pythonBootstrap.add_rule(PythonEnabler())
pythonBootstrap.load()

pythonGrammar = Grammar("python grammar")
pythonGrammar.add_rule(PythonTestRule())
pythonGrammar.add_rule(PythonCommentsSyntax())
pythonGrammar.add_rule(PythonControlStructures())
pythonGrammar.add_rule(PythonDisabler())

所以基本上,您可以简单地使用 some_grammar.disable()some_grammar.enable!
