Manual execution of blocks

I’m trying to generate arduino C code using scratch block. I can’t store generated code because of vm architecture. For example, this is code for builtin ‘if’ statement

if (args, util) {
        const condition = Cast.toBoolean(args.CONDITION);
        if (condition) {
            util.startBranch(1, false);
        }
}

I want to make something like this:

if (args, util) {
        const condition = Cast.toString(args.CONDITION);
        const body = recursive_call_for_inner_blocks(inner_blocks);
        return `if (${condition}) { ${body} }`;
}

How can I do this? Maybe there is a better way to generate code using scratch blocks?

@caxapexac scratch-blocks was originally branched from Blockly, which does convert blocks into code. It may be easier for you to start there: https://developers.google.com/blockly

Can you give me examples please?

It’s Smalruby ( https://github.com/smalruby/smalruby3-gui/ and https://smalruby.jp/smalruby3-gui/ ) that is forked from scratch-gui. Smalruby can generate from scratch’s block to ruby code. And it can convert ruby code to scratch’s blocks.
