Is there anything posted that gives an overview of how the source code to LiveCode works/is organized? I know that the source is all there and I can read it, but that would take a long time :) I'm still learning C++ (been many years, but I learned C while in college), but following the code doesn't seem too bad.
I'm specifically looking at the parsing of livecodescript stacks with BOMs. I think I know where the file is ultimately processed (the stream of it anyway), but I can only work backward so far and get stuck. So, I guess a more specific question would be where to start on the handoff between the IDE and the engine. As an example, I can see that when you turn off debug mode, the message box ends up with "send script pScript to pObject". I want to follow the problem statements through to see where they lead and compare what works to what doesn't. I'm using the message box (single line) to test syntax. I get the same results whether debug mode is on or off. The local file includes the UTF8 BOM (verified by getting the first 3 bytes). The actual file I'm using is the Scriptifier (URL from an earlier thread). I get the same results for "binfile:/" and "https://"; forms, so I've only included one below. I observe that "url" keyword is required (will need to adjust the documentation syntax, looks to be the same back to at least 7). So far I've observed the following fails silently (no error message returned): go [to] url "binfile:/...livecodescript" --should work The following fail with an error (LC9 gives "message" as hint, LC8 gives the actual script line as a hint "go..."): go [to] [stack] "https:...livecode" --missing url go [to] [stack] "binfile:/...livecodescript" --missing url go [to] stack url "binfile:/...livecodescript" --should work These work: go [to] [stack] url "https:...livecode" go [to] [stack] "/(full path)/Scriptifier.livecodescript" go [to] [stack] byte 4 to -1 of url "binfile:/...livecodescript" --assumes UTF8 BOM The current develop build has the same issues (at least for me). I can see in the code where it looks like the BOM should be accounted for (MCDispatch::doreadfile or MCDispatch::trytoreadscriptonlystackofsize depending on branch). It looks like the URL keyword will correctly parse a binary stack, but fails on livecodescript with a BOM. I put 2 files on a server that I control (with and without the UTF8 BOM), and the livecodescript will load fine from https:// if no BOM is included. Apologize for the long post, but wanting to contribute to the community if I can.
