Examples

It is better to understand the components and widgets by checking an example.
the following example shows how to make a Menu in a simple way, the Menu class is used for single answer questions among a list of options. The options can be of the Text class or of the text type str, if the Text class is used it is possible to specify individually a text color, and a background color with the parameters fg and bg. The colors must be a text string with the hexadecimal format that is usually used in web development with html or using the Colors class you can search a color by its name, the references of the color and its name are in this page.

from pyemenu import Colors
from pyemenu import Text, Title, Menu

def main():
    # Foreground and Background Colors using Colors Class
    foreground = Colors.BlackOlive
    background = Colors.GhostWhite
    # Options as a Text() type object 
    # It is possible to use just a str 
    language1 = Text('Python')
    language2 = Text('JavaScript')
    language3 = Text('Java')
    language4 = Text('C++')
    language5 = Text('C#')
    language6 = Text('Swift')
    language7 = Text('Go')
    language8 = Text('Kotlin')
    # Options must be pass as a list
    options = [
                language1, language2, language3, language4,
                language5, language6, language7, language8
                ]
    # The title could be pass a str or a Title
    title = Title('What is your favorite?', fg=Colors.DarkBlue, bold=True)
    # The same by the cursor you want to use
    cursor = Text('>>', fg=Colors.DarkBlue)
    # it is possible to create a Menu just passing the options to be choosen
    menu = Menu(options, title=title, cursor=cursor, fg=foreground, bg=background)
    # The method print is used to show the menu on terminal
    menu.print(
                wrap=3,
                highlight=True,
                title_align='center',
                title_decorator='*',
                title_padding_bottom=True, 
                padding_bottom=True,
                padding_up=True
                )
    # Widgets has a attribute call answer to get data input for the user
    print(f"\nThe selected value is: {menu.answer}")

if __name__ == '__main__':
    main()

if you use this example your output would be something like this:

The next code show an example for creating a checkboxlist menu for selecting multiples options from a list

from pyemenu import Colors, Title, Text, Checkboxlist

def main():
    foreground = Colors.IndianRed
    background = Colors.LightGoldenrodYellow
    dog = Text('My Cool Dog', fg=Colors.DarkBlue, bg=Colors.Gold)
    options = [
        'French Poodle', 'Chihuaha', 'Dalmata',
        'Golden Retriever', 'Labrador', 'German Sheppard',
        'Akita', 'Galgo', dog
    ]
    title = Title('What is your favorite/s dog/s?', fg=Colors.SeaGreen, italic=True)
    cursor = Text('➤', blink=True, fg=Colors.Navy)
    question = Checkboxlist(options, multiselect=True ,
                            title=title, cursor=cursor, fg=foreground, bg=background)
    question.print(  
                    wrap=3, highlight=True,
                    fg_hl=Colors.black, bg_hl=Colors.SkyBlue,
                    title_padding_bottom=True, 
                    title_padding_up=True
                    )
    if question.answer == None:
        print(f"\nDo you really like dogs? ")
    elif len(question.answer)==1:
        print(f"\nMy Favorite Dog is {question.answer}")
    else:
        print(f"\nMy Favorites Dog are {question.answer}")
    

if __name__ == '__main__':
    main()

One of the new features of PyeMenu is the possibility to create a Form for get survey information or whatever you want from the users. So, this example show that it is possible to print a logo or your app above the menu.

from pyemenu import Colors, Title, Text, Form, Entry, Button


logo = r"""
  ____        _   _     ____     __     __   U _____ u   __   __ 
 / __"| u  U |"|u| | U |  _"\ u  \ \   /"/u  \| ___"|/   \ \ / / 
<\___ \/    \| |\| |  \| |_) |/   \ \ / //    |  _|"      \ V /  
 u___) |     | |_| |   |  _ <     /\ V /_,-.  | |___     U_|"|_u 
 |____/>>   <<\___/    |_| \_\   U  \_/-(_/   |_____|      |_|   
  )(  (__) (__) )(     //   \\_    //         <<   >>  .-,//|(_  
 (__)          (__)   (__)  (__)  (__)       (__) (__)  \_) (__) 
"""

Logo = Text(logo, fg=Colors.Azure, bg=Colors.Navy)

def main():
    foreground = Colors.BlackOlive
    background = Colors.LightCyan
    placeholder = Colors.LightBlue
    name = Text('Name')
    last_name = Text('Last')
    age = Entry('Age', validation='int')
    email = Entry('Email', validation='email') 
    password = Entry('Password', validation='password')    
    data = [name, last_name, age, email, password]
    title = Title('Creating a New User', italic=True, bold=True)
    cursor = Text('~>')    
    form = Form(data, title=title, cursor=cursor, fg=foreground, bg=background,
                placeholder_bg=placeholder,
                )
    form.print(
                wrap=2,
                highlight=True,
                title_align='center',
                logo=Logo
                )
    print(f"Your Answers are: {form.answer}")

if __name__ == '__main__':
    main()
