Conditional Breakpoints

You can set breakpoints in your Xojo code that cause the debugger to appear when the line of code with the breakpoint is reached. This is incredibly handy to help understand and test your code.

Introspection

Introspection is a very handy and useful part of the Xojo language.

You can use it to examine a lot of the objects that are in memory at runtime. You can access the properties in those objects, call methods on those objects and even create new instances (with some caveats here).

But there are limits to what you can do with it. You can’t use it to create things that do not exist at runtime because they’ve been stripped out when your app was built.

Easy as Pi: GPIO updates

We are always keen to see apps and projects that Xojo developers have made for their Raspberry Pi 2 and Raspberry Pi 3 single-board computers. Especially since Xojo 2019r1 when building for Pi Desktop and Console is free with Xojo Pi!

I am pleased to announce some updates to our GPIO project to make it even easier to use more types of hardware in your Raspberry Pi projects.

Code Refactoring Tools

Wikipedia defines Code Refactoring as:

the process of restructuring existing computer code – changing the factoring – without changing its external behavior. Refactoring improves nonfunctional attributes of the software.

Did you know that Xojo has a bunch of refactoring features that can help make this process more efficient?
