        # teletype
        
        **teletype** is a high-level cross platform tty library compatible with Python 2.7 and 3+. It provides a consistent interface between the terminal and cmd.exe by building on top of [terminfo](https://invisible-island.net/ncurses/terminfo.src.html) and [msvcrt](https://msdn.microsoft.com/en-us/library/abx4dbyh.aspx) and has no dependancies.
        
        # Installation
        
        `$ pip install teletype`
        
        # I/O Utilities (teletype.io)
        
        ## Reading Key Strokes
        
        You can read keystrokes from stdin using `get_key`. Regular keys get returned as a string with a single character, e.g. `"a"`, `"1"`, `"&"`, etc., while special keys and key combinations are returned as a string description, e.g. `"space"`, `"f12"`, `"page-up"`, `"ctrl-c"`, etc. A listing of the supported key combinations are listed in the [`codes`](https://github.com/jkwill87/teletype/blob/master/teletype/codes/common.py) module.
        
        ```python
        from teletype.io import get_key
        
        print("Delete C:/ Drive? [y/n]")
        selection = ""
        while selection.lower() not in ("y", "n"):
            selection = get_key()
            if selection in ("ctrl-c", "ctrl-z", "escape"):
                selection = "n"
        if selection == "y":
            print("Deleting C:/ drive...")
            delete_c_drive()
        else:
            print("Leaving C:/ drive alone")
        ```
        
        ## Styling Output
        
        You can style strings with colours and effects using `style_format`. Styles can be passed in either as a space delimited string or in a collection (e.g. a tuple, set, list, etc.). The passed `text` string is then wrapped in the appropriate ASCII escape sequences and returned. When `print`ed the appropriate styles will be applied.
        
        Alternatively you can you just pass these same parameters to `style_print` and accomplish this in one fell swoop. `style_print` takes the same parameters as the regular print function and can be used in place. In python3 you can even import style_print as print and use it in place. In order to pull this compatibility off for python2, the `style` argument must be specified explitly when calling, however, e.g. `style_print("yolo", style="yellow")`.
        
        Lastly, you can use `strip_format` to clear a string of any escape sequences that have been previously applied.
        
        ```python
        from teletype.io import style_format, style_print, sstrip_format
        
        # All of these will do the same thing, that is print the message in red and bold
        print(style_format("I want to stand out!", ("bold red")))
        print(style_format("I want to stand out!", ("red", "bold")))
        style_print("I want to stand out!", style=["red", "bold"])
        
        # Styles are cleared afterwards so everything else gets printed normally
        print("I want to be boring")
        
        # If for whatever reason you want to unstyle text, thats a thing too
        text = style_format("I don't actually want too be styled", ("red", "bold"))
        print(strip_format(text))
        ```
        
        ## Cursor manipulation
        
        The package includes quite a few helper functions to move the cursor around the screen. These include `erase_lines`, `erase_screen`, `hide_cursor`, `show_cursor`, and `move_cursor`; all of which are fairly self explanitory. The only word of caution is to remember to reset cursor visibility as its state will persist after the python interpreter has exited.
        
        # Components (teletype.components)
        
        The package also includes components, higher level UI classes that are composed from the I/O functions and can be easily incorporated to any CLI application.
        
        ## SelectOne
        
        ```python
        from teletype.components import SelectOne
        
        picker = SelectOne(
            header="Your Favourite Animal?",
            choices=["dog", "bird", "cat", "monkey", "gorilla"],
        )
        choice = picker.prompt()
        print("Your choice: " + choice)
        ```
        
        ![Output](https://github.com/jkwill87/teletype/blob/master/_assets/select_one.gif)
        
        ## SelectMany
        
        ```python
        from teletype.components import SelectMany
        
        picker = SelectMany(
            header="Your Favourite Animals?",
            choices=["dog", "bird", "cat", "monkey", "gorilla"],
        )
        choices = picker.prompt()
        print("Your choices: " + ", ".join(choices))
        ```
        
        ![Output](https://github.com/jkwill87/teletype/blob/master/_assets/select_many.gif)
        
        ## ProgressBar
        
        ```python
        from time import sleep
        from teletype.components import ProgressBar
        
        iterations = 15
        
        def iterable():
            for _ in range(iterations):
                sleep(0.2)
                yield
        
        ProgressBar().process(iterable(), iterations)
        ```
        
        ![Output](https://github.com/jkwill87/teletype/blob/master/_assets/progress_bar.gif)
        
        ## Styling Components (teletype.components.config)
        
        You can set component primary and secondary styles using `set_style`.
        
        ```python
        from teletype.io import style_print as print
        from teletype.components.config import set_style
        from teletype.components import ProgressBar, SelectMany, SelectOne
        
        set_style(primary="yellow", secondary="magenta")
        iterable = range(25)
        choices = [1, 2, 3]
        
        print("Progess Bar", style="underline")
        ProgressBar(width=50).process(iterable)
        
        print("Select Many", style="underline")
        SelectMany(choices).prompt()
        ```
        
        ![Output](https://github.com/jkwill87/teletype/blob/master/_assets/style.png)
        
        You can also change character sets using `set_char(key, value)` where value is the unicode character you want to use and key is one of:
        
        - selected
        - unselected
        - arrow
        - block
        - left-edge
        - right-edge
        
        Lastly, you can also use **ascii_mode(enabled=True)** to quickly disable colour stylings and swap to a ascii-only character set.
