flyconsole 1.2

Modify the Terminal

Fly Console

Fly Console is build to easy manipulate the terminal xonsole in multiple aspects It is possible to change the color, clear the terminal or manipulate the position, visibility of the cursor and use custom input methods.

You can install it for python via pip here and you can view the source code on github here.

Documenation

Welcome to the documentation about the fly console package c:

The Documentation is based on the newest Version.

With this package it is possible to change the foreground and background color of the text in the terminal, write with or without line breaks, set the cursor position with different modes, show and hide the cursor or clear the console on specific parts.

Lets get right into it!

Writing to the Terminal

The most important part is writing to the terminal. This can done in two ways. Write a line without a break or write a line with a break at the end.

We can write with a break like this

from flyconsole import Console
Console.writeln('This is a test!')
Console.writeln('This is another test!')

The output will look like this

This is a test!
This is another test!

To write without a break we use

from flyconsole import Console
Console.write('This is a test!')
Console.write('This is another test!')

With the following output

This is a test!This is another test!

As we can see, there is no line break betweeen

Colors

First of all there are two ways to use colors It is possible to use just integers from 0 to 255. There are also predefined constants for the first 16 colors (0 - 15).

They can be imported as following

from flyconsole import Color

Now lets make the console colorful! To set the foreground color of the text you can just simply run

from flyconsole import Console, Color
Console.set_color(Color.RED)

But you are not limited to the foreground color. You can also only set the background color

from flyconsole import Console, Color
Console.set_color(background=Color.CYAN)

And as if that wasn't enough, you can combine these into one line

from flyconsole import Console, Color
Console.set_color(Color.RED, Color.CYAN)

This line will do the same as the two lines before.

At some point you may want to remove all Color effects. For this the following code does the job

from flyconsole import Console
Console.reset_color()

Pretty self-explanatory.

Lets hop on to the next part!

Cursor Maniplation

Before we can start there is one thing to say. The cursor module is a submodule of the console. You dont have to import it, you can just use it right away like this

from flyconsole import Console
Console.Cursor # Thats the Cursor sub module

There a nine methods for manipulation of the cursor The first is the simplest. To jump to a specific line and column just write the follwing

from flyconsole import Console
Console.Cursor.go_to(line, column)

If u want to go to the cursors home instead, you can write

from flyconsole import Console
Console.Cursor.go_home()

There are 4 methods to go relative amounts in different directions

from flyconsole import Console

# The Cursor will go one line up
Console.Cursor.go_up() 
# The Cursor will go n lines up
Console.Cursor.go_up(n)

# The Cursor will go one line down
Console.Cursor.go_down()
# The Cursor will go n lines down
Console.Cursor.go_down(n)

# The Cursor will go one column to the right
Console.Cursor.go_right()
# The Cursor will go n columns to the right
Console.Cursor.go_right(n)

# The Cursor will go one column to the left
Console.Cursor.go_left()
# The Cursor will go n columns to the left
Console.Cursor.go_left(n)

As you can see, the variable n is predefined with the value 1 so you dont have to write it again and again

You can also move the cursor down n lines and then go automatically to the beginning of that line with the following code

from flyconsole import Console

# n is predifned with 1
Console.Cursor.go_down_beginning(n)

The same also for going up

from flyconsole import Console

# n is predifned with 1
Console.Cursor.go_up_beginning(n)

Last but not least, you can go to a specific column via

from flyconsole import Console

# n is predifned with 1
Console.Cursor.go_to_column(column)

This can be usefull when u go up a line and want to be on another column

Private Modes

Private modes are some console sequences that may not work on every Terminal. To manipulate the visibility of the cursor we need private modes.

The visibility can be modified with

from flyconsole import Console

Console.Cursor.Private.hide()
Console.Cursor.Private.show()

Its obvious which method does what

Clearing the Terminal

There are six methods to clear the terminal or specific parts of it.

The first one and the most common one is there to clear the whole terminal

from flyconsole import Console
Console.Clear.clear()

To clear from the cursor to the end of the terminal you can use the next snippet

from flyconsole import Console
Console.Clear.cursor_to_end()

To clear from the cursor to the beginning of the terminal you can use this

from flyconsole import Console
Console.Clear.cursor_to_start()

You can also clear from the cursor to the end or start of the current line with

from flyconsole import Console
Console.Clear.cursor_to_end_line()
Console.Clear.cursor_to_start_line()

And you can also clear the whole current line with the following

from flyconsole import Console
Console.Clear.current_line()

---

Inputs

There are also some inputs you can use. In later updates there are coming more!

List Menu (Since V1.2)

A List Menu uses for its fields a Menuitem. You can also customize the key events with a KeyConfiguration.

To setup a List menu you can write the following

from flyconsole import ListMenu

menu = Menu(0) # 0 Defines the y coordinate of the menu
menu.add_item('Item A')
menu.add_item('Item B')
menu.add_item('Item C')
menu.enable() # Shows the menu and enables the Key Events

# After the menu is done you can get its result with
menu.result
# The result will return a MenuItem

When we look at the ListMenu init arguments

ListMenu(y:int=0, can_cancel:bool=1, can_escape:bool=1, key_configuration:KeyConfiguration=KeyConfiguration())

we can see, we can disable the [CTRl] + [C] cancel and the [ESC] key. The cancel and escape keys can also be modified in a KeyConfiguration

The Keyconfiguration looks like this

@dataclass
class KeyConfiguration:
    up: tuple = (72, 1)
    down: tuple = (80, 1)
    select: tuple = (13, 0)
    escape: tuple = (27, 0)
    cancel: tuple = (3, 0)

Foreach tuple the first argument is the keycode and the second argument defines if the key means something else. For example if you press an arrow key it will return (72, 1) and if u press [H] it will return (72, 0).
