NEW FEATURE: Considerations in returns

[MatiDragon-YT]

I don't know how to explain this without making it seem redundant...

Syntax

return [value]

Examples

return                ->   0051: return                    // default
return true           ->   0485: return_true               // default
return false          ->   059A: return_false              // default
return is false       ->   0AA1: else_return               // CLEO
else return           ->   0AA1: else_return               // CLEO
return 0              ->   0AB2: cleo_return 1 0           // CLEO
return 1@             ->   0AB2: cleo_return 1 1@          // CLEO
return 3@ 5@ 7@       ->   0AB2: cleo_return 3 3@ 5@ 7@    // CLEO
return (4@, 6@, 8@)   ->   0AA7: function_return 4@ 6@ 8@  // CLEO
return <5@, 7@, 9@>   ->   0AA8: method_return 5@ 7@ 9@    // CLEO

Never use OP 0AA7 or 0AA8, so you are probably typing something nonsensical.

They only exist as keywords
The command to call the function should not be included
I don’t really agree with this form of returning value references, we only need to update the keyword file.

About function commands:

return 0              ->   0AB2: cleo_return 0             // CLEO

what if I want to return zero from the cleo function?

in opcode form:

0AB2: cleo_return 1 0

how do I write it using just return?

[MatiDragon-YT]

oops sorry, I didn't notice that error, I corrected.

Yes and thank

[x87]

how would I write 0AB2: cleo_return 0 then? just return?

[MiranDMC]

This very risky. The distinction between gosub's and CLEO's return should be obvious. Worst debugging sessions I had was caused by muscle memory and using return instead of cleo_return. Scripts crashes without obvious reason.

[x87]

That's the idea. Just like end closes the innermost loop or if statement, return acts either as 0051 or 0AB2 depending on current scope. This resolution could be done in compile-time.

[MiranDMC]

Hm, ok. Will it work with functions having multiple exit points?

[MatiDragon-YT]

return undefined or return null or !return or return void(0)

@MiranDMC

if you do a code pre-processing, i.e. a text scanner, which identifies the matches and replaces them with the necessary text, there should be no problems with anything.

in fact @x87, can't you include in SannyBuilder, a tool to create these auto-replaceable texts? This is something extremely easy to do in JavaScript, with a String.Replacer() with a RegularExpression in the first parameter and a STRING in the second.

[MiranDMC]

Already done.
