A CLI for the Flet framework.

Fletil

A CLI for the Flet framework.

Features

• Exposes the standard run options for a Flet app.
• Implements "hot reload": reloads the targeted source file whenever changes are saved, attempting to preserve the running state of controls.
  • State to preserve must be specified by passing a unique ID and list of attribute names as data to the controls, eg. TextField(value="hello world", data={"_cid": "greet_text", "_state_attrs": ["value"]}).
  • If a Syntax error is detected during a reload, it is aborted.
• Developer buttons (a breakpoint button and code status indicator) can be temporarily injected into the page.

Installing

NOTE: this also installs Flet if it isn't present.

• From PyPI:
  • $ pip install fletil.
• From GitLab (NOTE: development is managed by Poetry):
  • $ git clone https://gitlab.com/skeledrew/fletil
  • $ cd fletil
  • $ poetry install

Usage

• Ensure script is import-friendly, ie. invoke runner with (doc):

if __name__ == "__main__":
    flet.app(target=main)

and not:

flet.app(target=main)

• Further help is available via $ fletil --help.
