Same here, if they use github more maybe they will put the docs on there too so we can push changes.

Geoff has wrapped up. @Paul_Lefebvre will now be giving a talk on Xojo: How It’s Made. Still don’t know what that means.

Edit: “Now”, not “not”

I wouldn’t encourage it. If I started over now, my API would be different.

Diving into the parts the components of Xojo, starting with the IDE.

  • Originally C++ with separate versions for Mac and Windows.
  • Rewritten in Xojo in 2004 (has it been that long?!?).
  • UI redesigned in 2010-13.

The IDE has approximately 365k lines of code with about 7.5 GB of source code. There are about 1200+ project items, and it takes about 30s to open the IDE project. (This is down from about 2 minutes from when Paul started.) It takes about 1 minute to run the IDE project and 2 minutes to build the local Dev build.

When working on the IDE, they launch the Xojo IDE through the Xojo IDE, and then can launch another IDE through the IDE running through the IDE.

Now discussing the compiler and how that works. The short version is, it’s now a multi-pass compiler for all platforms, but still has custom compiler for Intel 32-bit.

What does “cycle” mean in this context? Each major release? Minor .x release?

I asked this above, hopefully Geoff will let us know later in a post here.
