cliasi 0.2.2

Have a nice looking, simple cli in seconds

cliasi (cli easy)

Output pretty command line text without hassle.
This is mostly a collection of pretty print commands

By using colorama, the text you see below is colored nicely.

Basic Usage

from cliasi import cli

cli.success("It works!")
# > ✔ [CLI] | It works!

cli.messages_stay_in_one_line = True
# The next few lines will get overwritten
cli.info("blah")
cli.warn("doing something dangerous")
# > ! [CLI] | doing something dangerous

# You can even ask for input and the input will disappear
cli.log("Got input: " + cli.ask("Give input: "))
# > LOG [CLI] | Got input: test

Prefix and Cliasi instances

Sometimes you might want to indicate different parts of your program working.
You can do that by having another instance of Cliasi with another prefix

from cliasi import cli, Cliasi  # Default shared Cliasi instance

cli.update_prefix("MANAGE")
cli.fail("Management failed")
# > X [MANAGE] | Management failed

def calculate():
    # Another part of your program could have its own instance
    clisi = Cliasi("CALC", use_oneline=True)
    clisi.info("Calculating...")
    # > i [CALC] | Calculating...
    # Although it might be better to use other methods for waiting

Animations

Some processes might take a few seconds to complete and you dont know how much the process is done (you cant use a progress bar)
In that case you can use either a blocking or non blocking animate method.

from cliasi import cli

# This will wait for three seconds and display an animation
cli.animate_message_blocking("Saving files, press CRTL-C to stop", 3)
save_data()

# But if you want to wait for something to finish and display something nice in the meantime
task = cli.animate_message_non_blocking("Waiting for a process to quit")
# Put your processing logic here
do_stuff_that_takes_time()
task.stop()  # Stop the animation
cli.success("Process quit")

Progress Bars

You can also have a progress bar which adapts to the size of your terminal
This is the "static" version which you just call whenever you get an update.

from cliasi import cli

processed, total = 0, len(calculate_queue)
while not calculate_queue.is_empty():
    cli.progressbar("Calculating items...", processed / total)
    calculate_next_item()
    processed += 1

cli.success("Calculation complete")
# This will show a progress bar that will only update when a calculation has finished.
# Potentially bad if it gets stuck on a calculation

Or if you want to have the bar be animated while waiting for progress

from cliasi import cli

task = cli.progressbar_animated_download("Downloading files.")
download()
task.update(10)
# You can also change the message while in the process
task._message = "Extracting"
extract()
task.update(40)
extract_again()

task.stop()
