bsddialog 0.4 and LGPL-Free bsdinstall

Posted on October 2, 2022

The bsddialog project provides bsddialog and libbsddialog, an utility and a library to build TUI dialogs and widgets. The version 0.4 is out!

This release provides mainly new features and changes to integrate bsddialog (utility) with scripts in FreeBSD BASE system. Finally, it is possible to install FreeBSD using BSD-Like licensed tools/code only (at least like a proof of concept).

The version 0.4 is already in FreeBSD, it changed the utility heavily. The version 0.3 modified some well tested structural code in the library (mainly word wrapping and text auto-sizing). So I need a while to test and to change the OS to use the new features. Actually the changes are small and very simple but they are used by tens of thousands of lines of code, so again I need a while to test.

However, I changed the last CURRENT iso FreeBSD-14.0-CURRENT-amd64-20220930-42dc8696df5-258315-bootonly.iso to test bsddialog and bsdinstall with bhyve on my laptop. The result is: It is possible to install FreeBSD using BSD-Like licensed code only!
