#Rhai #RustLang Easter Egg 😂

https://docs.rs/rhai/1.0.2/rhai/type.StaticVec.html

Anyone knows how to talk to ST7789 Display on 3-Wire (9-bit) Mode ... Over 8-bit SPI? Do we pack our bits into 9-byte chunks? (9 bits x 8) Thanks! 🙏

#Rhai Abstract Syntax Tree will have Gnarly Nested Nodes ... Transcoding to uLisp will be an interesting challenge!

How to Transcode #Rhai Script to #uLisp? We walk the Abstract Syntax Tree and convert every node

#Rhai Script runs OK on #BL602 WebAssembly Simulator ... But to run on Real BL602 Hardware we shall transcode to uLisp

#Rhai lets us register our #RustLang Module with the Script Engine ... So calling the #BL602 Rust Wrapper is no problemo!

We have modded #Blockly to generate #Rhai Scripts for #BL602 Simulator

https://github.com/lupyuen2/blockly-bl602

What is #Rhai Script? It's a #RustLang-like Scripting Language that we're porting to #BL602 Simulator

https://github.com/lupyuen/bl602-simulator/tree/main/bl602-script

Now we add #Rhai Scripting to #BL602 Simulator ... The Drag-n-Drop Way!

#Rhai Scripting Engine parses our Rhai Script and produces an Abstract Syntax Tree ... We'll walk the tree and transcode to uLisp for #BL602

How we'll Transcode #Rhai Script to #uLisp for #BL602

https://lupyuen.github.io/articles/rustsim?22#appendix-rhai-scripts-on-bl602

Rhai Scripts won't run on #BL602 Hardware ... But we could transcode to #uLisp and run them on BL602
