Read more about different message types and see visualizations in the documentation here.

Animations

One of the main features of cliasi is the ability to display animations while waiting for something to finish.

# File: examples/readme_demo.py
from cliasi import cli

# This will wait for three seconds and display an animation
task = cli.animate_message_non_blocking(
    "Saving files...",
    message_right="[CTRL-C to abort]",
    messages_stay_in_one_line=True
)
do_stuff()
task.update("Files saved, waiting for process to quit", message_right="70%")
tell_process_to_quit()
task.stop()
cli.success("Process quit", message_right="100%")

Catching exceptions

cliasi also catches exceptions and displays them in a pretty way. This then looks something like this:

# exception_message.py
import cliasi

# Importing cliasi automatically installs the logging handler
raise ValueError("An example error")

Example CLI output (uncolored, see colored version in docs):

X [CLI] | Uncaught exception:
X [CLI] | Traceback (most recent call last):
        |   File "examples/exception_message.py", line 4, in <module>
        |     raise ValueError("An example error")
        | ValueError: An example error

Other features

cliasi has many more features like:

• Logging integration
• Custom message alignments
• Customizable progressbars (with PBCalculationMode)
• And more!
