Package: dfly-breathe
BreatheA convenient API for creatingdragonflygrammars with automatic CCR (continuous command recognition).Very quick start-upCommand activity can be controlled either using dragonfly contexts or using "enable" and "disable" commands.All commands which match the current context may be chained together in any order in the same utterance.Installationpip install dfly-breatheInstructionsIf you are creating a command set from scratch, start by cloning theBreathe skeleton project,
which will give you a file structure to start with.Adding commandsfromdragonflyimport*frombreatheimportBreathe,CommandContextBreathe.add_commands(# Commands will be active either when we are editing a python file# or after we say "enable python". pass None for the commands to be global.context=AppContext(title=".py")|CommandContext("python"),mapping={"for each":Text("for  in :")+Key("left:5"),"for loop":Text("for i in range():")+Key("left:2"),"from import":Text("from  import ")+Key("home, right:5"),"function":Text("def ():")+Key("left:3"),"(iffae | iffy)":Text("if :")+Key("left"),"iffae not":Text("if not :")+Key("left"),"import":Text("import "),"lambda":Text("lambda :")+Key("left"),"while loop":Text("while :")+Key("left"),"shell iffae":Text("elif :")+Key("left"),"shells":Text("else:"),"return":Text("return "),# ------------------------------------------------"method <snaketext>":Text("def%(snaketext)s(self):")+Key("left:2"),"function [<snaketext>]":Text("def%(snaketext)s():")+Key("left:2"),"selfie [<snaketext>]":Text("self.%(snaketext)s"),"pointer [<snaketext>]":Text(".%(snaketext)s"),"classy [<classtext>]":Text("class%(classtext)s:")+Key("left"),},extras=[Dictation("snaketext",default="").lower().replace(" ","_"),Dictation("classtext",default="").title().replace(" ",""),])For full details of the available contexts, actions and extras you can use, see thedragonfly documentation.Loading command filesBreathe provides the command "rebuild everything" for reloading all of your commands,
allowing you to modify commands without restarting the engine. In order for this to work,
your command files need to be loaded by giving your directory structure toBreathe.load_modules().For example, given a directory set up like this:|   _main.py
|   __init__.py
+---my_commands
|   |   __init__.py
|   +---apps
|   |       chrome.py
|   |       notepad.py
|   |       __init__.py
|   +---core
|   |       alphabet.py
|   |       keys.py
|   |       __init__.py
|   +---language
|   |       c.py
|   |       python.py
|   |       __init__.pyInside_main.py, the file which will be loaded by the engine, we load all of our command
files by passing a dictionary with keys representing folder names and values being either a
single module to import, a list of modules to import, or another dictionary. Like so:frombreatheimportBreatheBreathe.load_modules({"my_commands":{"apps":["chrome","notepad"],"language":["python","c"],"core":["keys","alphabet"],}})Given this setup, calling the "rebuild everything" command will reload all of your command
files, making any changes available.Custom top level commandsAdvanced feature, if you are just getting started you should ignore this.Top level commands allow you to embed sequences of breathe
CCR commands inside other commands. This gives finer control over
the way in which commands are recognised and executed.Top level commands should be added in a separateadd_commandscall
with thetop_leveloption set toTrue. A couple of new elements -ExecandCommandsRef- are required to control them.For example in the following,
the first command implements "greedy" dictation by creating
a top level command which recognises between zero and twelve of the commands
which are active in the current context, followed by a dictation command
which will consume the rest of the utterance. The second allows an arbitrary sequence of commands to be repeated a
given number of times.fromdragonflyimport*frombreatheimportBreathe,CommandsRef,ExecBreathe.add_commands(None,{"[<sequence_of_commands>] dictate <text>":Exec("sequence_of_commands")+Text("%(text)s"),"<sequence_of_commands> and repeat that <n> times":Exec("sequence_of_commands")*Repeat("n"),},[Dictation("text"),IntegerRef("n",1,100),CommandsRef("sequence_of_commands",12)],top_level=True)ExamplesMy commandsMathfly
