Hey, just wanted to share some of my work using kotlin scripting: https://openrndr.discourse.group/t/improved-live-coding-with-orx-olive/106 and

[Nikky]

really cool, i have to play with that at some point, can this take external input.. lets say watch a file or socket ? or analyze sound ?

that did not seems to use .kts files.. so are you using kotlin scripting or just watching and recompilg the file while holding into the data ?

[edwinRNDR]

@Nikky that's described in the discourse post. I watch the .kt then generate a kotlin script wrapper around it and feed it to the kotlin scripting host

[Nikky]

ohh thats a cool solution

[edwinRNDR]

Should be possible to introduce 'persistent' parts too, for sound and video streams, but that's currently not supported in this setup

[edwinRNDR]

would be fun to try it with things like https://plugins.jetbrains.com/plugin/11955-teamhub

@edwinRNDR I'm needing a similar functionality, but I take the script as a string and put it on a kafka topic and I am doing something some of hacky... I take the user script string and inject into a larger class string and compile that

[Luis Munoz]

@edwinRNDR can you point in your code where it does the eval or compile. I am don't know what this rx-olive thing is or how it suppose to work, is that a separate app to where the user types in the code?

[Luis Munoz]

here is how I;m doing the scripting

[edwinRNDR]

https://github.com/openrndr/orx/tree/master/orx-olive/src/main/kotlin this is the sourcecode for orx-olive. there is some code that is specific to making things work with OPENRNDR but I think the part you are looking for is in the ScriptObjectLoader files

[Luis Munoz]

thank you, funny you are doing something similar to me which is creating a string with variables to compile

[edwinRNDR]

yeah 🙂

[Luis Munoz]

I didn't understand in your post what you were saying about Antlr grammar files.

[Luis Munoz]

I thought there might a way to take teh script and parse it then I'm not sure, something cleaner than string injection

[edwinRNDR]

there's a mode (that is used in the video) that watches .kt files for changes, it looks for a specific part in the code (that is very specific to how OPENRNDR works) and wraps that in a script

[Luis Munoz]

so you use the parser to find that specific part in the code

[Luis Munoz]

?

[edwinRNDR]

likely there are simpler ways but I may eventually want to do a bit more analysis of the sourcecode, so opted for using Antlr for parsing

[Luis Munoz]

thanks for sharing, one last question, can you link to where you do the parsing I can't find it

[edwinRNDR]

ah yeah, that's here https://github.com/openrndr/orx/blob/master/orx-kotlin-parser/src/main/kotlin/ExtractProgram.kt not the best ever 🙂
