This is a demo of a very basic GUI using WebPerl. It consists of a local web server, which includes code to access an SQLite database, and this web server also serves up WebPerl code to a browser, where the GUI is implemented as HTML with Perl.
To get this to work, you will need to copy the webperl.js and the
three emperl.* files from the main web directory to the web
subdirectory in this project.
Note that this should not be considered production-ready, as there are several key features missing, such as HTTPS or access control.
Also, a limitation is that the server does not know when the browser window is closed, so it must be stopped manually.
You can pack this application into a single executable using:
DOING_PAR_PACKER=1 pp -o gui_basic -z 9 -x -a gui_basic_app.psgi -a web gui_basic.pl
Note: I'm not yet sure why, but sometimes this fails with errors such as "error extracting info from -c/-x file", in that case just try the above command again.
