Recent Changes

Here you can find a list of recent changes in the code for Q OS that is available by downloading the repository or using the Clone in Desktop feature in GitHub.

Every day that changes are made to the Q OS code is considered an Update. So Update 1 would be the first day of development and Update 3843 would be the 3843rd day. A decimal point after an update number indicates a patch made the same day as a Update. So Update 3.4 would be the 4th patch made on the 3rd day, and Update 38431.483 would be the 483rd patch on the 38431st day.

The update numbers should be the date when the changelog is written.

Update 2.2

• When clearing the screen using the clear or clear -i, or by exiting the Writer interface by pressing Control, the entire screen is now cleared where before the 25th line was not cleared and was also very difficulty to modify and write text on in the Writer interface.
• There is now a new interface for the Writer text editor that includes a similar header to the Welcome to Q OS screen

Update 1.1

• Fixed an issue with no text being displayed in the Q OS Terminal screen.

Update 1

• Improved the nano text editor by adding support for writing multiple lines of text, adding a way to close the nano session properly (Press Control) and fixed the issue with the top and bottom areas of the nano editor not displaying properly.
• Added new variables in uint8 form to detect when a nano session is open and if it is then the enter and control keys are used to make a new line and terminate the open nano session respectively. When a nano session is not open then the enter and control keys will execute the current command written in the Q Terminal and display a warning message that control is not properly implemented yet respectively.

Initial Commit

• You are able to load the OS using the qemu visualiser but since no boot-loader is present yet it will not run on an actual PC
• The OS can be built by executing build.sh. Makefile implementation coming soon.
• The kernel is currently written in a mix of Assembly and C.
• You can enter commands in the Q OS Shell but it only supports 'nano' and 'help' at the moment, with a very buggy interface for the nano text editor that is not fully implemented yet
• When you first boot into Q OS you get a message saying Welcome to Q OS.
