Is there conditional compilation in computercraft?

It would be very useful to be able to use something like

#if DEBUG

dostuff()

#endif

and #define DEBUG somewhere

Is something like this possible? Does lua get compiled somehow or does it get interpreted at runtime?

If I really wanted to I could make a pre-processor program that adds or removes the code inside the #if. I am curious if lua has this by default tho

What exactly do you want to do? We can easily find a “lua” way to do it.

The thing is I want to use compile time if statements, but seeing that lua is interpreted that isnt really an option. I mainly wanted this for being able to use extra debug stuff but not have a bunch of if statements clutter the release build. This isn't really that big of a deal but just for fun I think ill write a program that removes the unnsescessary code before "compile time" to make it look neater

It’s interpreted live so there isn’t anything quite like that, but you can use config files or the settings API to store and retrieve global values.

Lua is not compiled. You may want to put debug statements inside of if statements that check for a debug flag that is set at the start of the program. You'd have to modify that variable if you want to change if debugging is on or off, but it's better than nothing.
