Web-based UI for Conway Game of Life
Project description
Web UI for Conway Game of Life
This package is a Web interface for package conway-life.
Installation
Use PyPi package life-web-ui
python3 -m pip install --upgrade life-web-ui
Usage
Package installs an executable script life-start
(via common entry_points
configuration option,
so depending on your local settings it may or may not be in your $PATH
)
Running this command will start a local server and open it in the default browser. To exit,
press Ctrl-C
to quit the server and close the browser tab.
life-start [-h] [--log {debug,info,warning,error,critical}] [-p PORT]
[--cell PIXELS] [--space PIXELS] [--padding PIXELS] [-d]
Run Web UI for Game of Life
optional arguments:
-h, --help show this help message and exit
--log {debug,info,warning,error,critical}, --log_level {debug,info,warning,error,critical}
Logging level (default = debug)
-p PORT, --port PORT Port (default = 13882)
--cell PIXELS, --size PIXELS
Size of cell in pixels (default = 20)
--space PIXELS Spacing between cells in pixels
--padding PIXELS Canvas padding in pixels
Implementation notes
life-start
will run a local Flask server. All computations are done in the server
(not in the browser), synchronously on the Step
command and asynchronously on Walk
or Run
.
Asynchronous execution is done with a background Python thread with results polled by the browser.
(Walk
is different from Run
in the background thread being suspended between polls).
There is also a short-lived background thread on startup to open Web browser (after a short delay
to make sure server has had time to start). This won't happen if -d/--dev
option is used (see below).
Development
For testing purposes, start the server with this command:
FLASK_ENV=development <VENV_ROOT>/bin/python3 <GIT_ROOT>/py-web/src/life_web_ui/__init__.py -d --log debug
Virtual environment installed under VENV_ROOT
must have all dependencies listed in
setup.cfg configuration file for the package (install_requires
).
