HISE Scripting Framework

Christoph Hart

Well, this will lead to disastrous errors on a apocalyptic scale as soon as you compile plugins :)

d.healey

Uh oh... tell me more!

Christoph Hart

Scripts will be embedded using the relative path from the project folder / or global folder as identification. Think of it like a big JSON object:

"scripts":
{
    "{PROJECT_FOLDER}Script1.js": "onInit...",
    "{PROJECT_FOLDER}Script2.js": "include(\"{GLOBAL_FOLDER}somethingElse.js\"); onInit...",
    "{GLOBAL_FOLDER}somethingElse.js": ...
}

Now using absolute file paths may work, but it's pretty much undefined behaviour and can go wrong on certain OS version or under rare conditions (the other way is well tested on all platforms).

What I can offer is the same mechanism that exists for sample folder relocation: a file in the "real" GlobalScript folder (the %APPDATA%/HISE/GlobalScriptFolder) called LinkWindows / LinkOSX that contains the path to the actual folder (in your case the repository root folder) and HISE will resolve this during development as well as when compiling.

d.healey

Ah I understand now. Yes that would be a very good solution I think.

Took a quick look on GitHub. Very good work Dave, can I suggest that one of your videos covering how to deploy this in the development process would be really useful.

d.healey

Once I've cleaned up the code a little and added more comments I'll do a little video.

I've added a bunch of Sublime Text 3 Snippets for HISE to the repo - I'm not sure I'll be adding any more as I'm pretty much doing everything directly in HISE now, if you have some snippets you'd like me to add to the repository just let me know :)

Has this been implemented?

Christoph Hart

Not yet, but I'll try to do it soon. I am currently in vacation until Octobre 2nd, so I'll be offline the next days.

d.healey

Enjoy your break! :)

Christoph Hart

Alright, I've added this feature now:

Tools -> Redirect script folder creates a link file in the original location %APPDATA%/HISE/scripts which points to the selected directory. From then on you can use

include("{GLOBAL_SCRIPT_FOLDER}MyFileInNewLocation.js");

Exported plugins embed this script into their binary. If you want to change the location again, either delete the link file manually or choose another target directory.

d.healey

The redirect doesn't seem to work on Linux, it creates a LinkWindows file that contains the correct path but it doesn't resolve when I hit compile and gives a file not found warning

Christoph Hart

Time for a LinkLinux file ;)

But I need to check what is the recommended location for storing persistent app data so if you know some best practices on Linux, let me know...

d.healey

Most apps seem to use a hidden folder in the home/username directory as Hise is doing now. Other put it in some obscure sub folder of the usr or etc directories, I think the home/username directory is fine, although it can look a little cluttered it keeps everything in one place.

Christoph Hart

I think I fixed it, but am too lazy to boot up my VM, compile HISE and check, so let me know if it's still broken.

d.healey

I think you broked it ;)

d.healey

Just downloaded the fixed version. Works perfectly :) thank you.

Christoph Hart

Yeah, I should at least have tested compilation before submitting - it was broken on all OS...

d.healey

The global script folder system is working great but I was thinking. Could this also be the default search path for MIDI processors that are connected to external scripts? That way I can put all of my generic external scripts at the global script location and if I change that location the project will still be able to find them without me having to relink each one. Would be handy if it could search sub-folders automatically too or if we could setup a sub folder for these external scripts.

Christoph Hart

I wouldn't make it a default, but if you're external script resides in your global script folder, there's no reason why it shouldn't choose to save the reference like this: {GLOBAL_SCRIPT_FOLDER}MyExternalScript.js instead of the absolute path. If this isn't true, it's a bug :)
