In my session at XDC 2023, I talked about ways to design your apps so you reuse code across platforms. The first project is JSONReader, so let’s dive in.

Xojo’s Code Editor now lets you move a line or a selection up or down or duplicate entire lines (or a selection). To swap lines, put the cursor on a line and press Option+Up Arrow (Mac) or Alt+Up Arrow (Win/Linux) to move the line up in the code. Press Down arrow to move down.
Comments closedA feature in some other languages you may have seen is something called matrix math. These are operations you can perform on matrices, which are 2-dimensional arrays. Xojo does not have any matrix math functions built in, but using the Extends command you can add your own.
Comments closedIn Xojo 2022r4, we have updated our SQLite library to SQLite v3.39.4. I thought I’d highlight a few notable upgrades including: STRICT tables
PRAGMA table_list
RIGHT and FULL OUTER JOIN
Built-in JSON support
Like most file systems these days, Windows lets you have rather long filenames. But it was not always so! When Microsoft first bought what was…

For Xojo 2022r3, the team worked on a wide variety of things for the Bug Bash. Two notable areas that I worked on were the Code Editor and the updates to the Syntax Help Area and I thought you might like to hear a bit about them.

Comments closedI was recently asked if there was a way to use Xojo Canvas Graphics to draw using the math X-Y coordinate system. First a little background. In Xojo (along with Java, .NET and many other languages), graphics are drawn where (0,0) is at the top left, X increases to the right and Y increases down. Other languages or APIs (Cocoa, for example) use a system where (0,0) is at the bottom left, X increases to the right and Y increases up.

Comments closedThe Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970. You’ve probably seen this around in some form or another, but I ran across it again recently and thought it would be fun to implement in Xojo.
