pacflypy 0.2.8

Command Class

The Command Class in pacflypy is a class for running commands in the terminal.

But wait, before you think that’s too simple, here are a few examples:

from pacflypy.command import command

# We run a simple command without saving the output
# We initialize the command, for example, we use: 'apt-get install -y wget axel'
cmd = command(program='apt-get', safe_output=False, shell=False)
cmd.arg('install')
cmd.arg('-y')
cmd.arg('wget')
cmd.arg('axel')
# Now we quickly print the command to the terminal, but this is not important
print(cmd.get_command())  # This will show you the full command as a string, also 'apt-get install -y wget axel'
# Now we run the command
cmd.run()  # That's all you need, this will execute the command

# Now we will get the architecture with dpkg
cmd = command(program='dpkg', safe_output=True, shell=False)  # Initialize the command
cmd.arg('--print-architecture')
print(cmd.get_command())  # This will show you the full command as a string also, 'dpkg --print-architecture'
cmd.run()  # That's all you need, this will execute the command and save the output and now we get it
stdout = cmd.stdout()  # Get the stdout
stderr = cmd.stderr()  # Get the stderr
print('The architecture is: ' + stdout)

Maybe that is too complex, but the pacflypy module includes a wrapper for this. Here is an example with the same commands:

from pacflypy.system import run  # Include the wrapper in the namespace

# We will run 'apt-get install -y wget axel'
run('apt-get install -y wget axel')

# For saving output
stdout, stderr = run('dpkg --print-architecture', safe_output=True)
print('The architecture is: ' + stdout)

Crazy, that was really fast. But the Command Class has a few more features, maybe you want to make 2 commands with the same program, for example:

from pacflypy.command import command
# We use APT
cmd = command(program='apt')
cmd.arg('update')
cmd.run()
print(cmd.get_command())
cmd.reset()
cmd.arg('install')
cmd.arg('-y')
cmd.arg('wget')
cmd.arg('axel')
print(cmd.get_command())
cmd.run()

But the Pacflypy module has not only the nice command class, maybe you want a little bit of style for your terminal, for example:

from pacflypy.style import styling

# We take now, red, blue, green, and cyan
red, blue, green, cyan = styling.color(2), styling.color(3), styling.color(1), styling.color(6)
# Now we will print the red text
print(red + 'Hello World' + styling.reset)
print(blue + 'Hello World' + styling.reset)
print(green + 'Hello World' + styling.reset)
print(cyan + 'Hello World' + styling.reset)

# We take Styling, bold and italic
bold, italic = styling.style(1), styling.style(2)
print(bold + 'Hello World' + styling.reset)
print(italic + 'Hello World' + styling.reset)

# Maybe you want a little bit more, for example, color and style
green_bold = styling.pair(1, 1)
print(green_bold + 'Hello World' + styling.reset)

# Or use directly the Print Function
styling.print(text='Hello World', style=1, color=1)

But you must know, colors and styles have a code, for example:

"""
        Color Codes:
        0 - Reset
        1 - Green
        2 - Red
        3 - Blue
        4 - Yellow
        5 - Black
        6 - Cyan
        7 - Magenta
        8 - White
        Style Codes:
        0 - Reset
        1 - Bold
        2 - Italic
        3 - Underline
        4 - Strike
        5 - Reverse
        6 - Hidden
"""

With these codes, you can use the style and color codes in your project, and this is better than with the ‘curses’ module.

Control File Rendering

Yes, I have a little module included for control file rendering, I don’t know why, but I have filled it.

Here for example:

import pacflypy.control as control
import pacflypy.system as system

user = 'whoami'
path = system.path.join('home', user, 'control')
with open(path, 'r') as f:
    data = control.load(f)
    print(data)
package_name = data['Package']
package_version = data['Version']
package_architecture = data['Architecture']
package_maintainer = data['Maintainer']
package_description = data['Description']
# And many many more, here you can find all data from a control file

Now we create a control file with my module:

import pacflypy.control as control

data = {
    "Package": "test",
    "Version": "1.0",
    "Architecture": "all",
    "Maintainer": "Pacflypy",
    "Description": "This is a Test Package"
}

with open('control', 'w') as f:
    control.dump(file=f, data=data)

And now you have successfully created a control file, but the Pacflypy module has not only the control file rendering.
