Extract only the relevant bits of data from your project for your mappers [More]
If you want to allow others to make maps for your game, but don't have a custom map editor, you might be tempted to give them the entire source code. However, a mapper only needs a small subset of your code to create maps for your game: the basic visual data of your mappable turfs, objs, and mobs.

This library allows you to extract all of the data for your mappable atoms and create a separate project just for your mappers in as little as a single line of code:

var/MapDataExtractor/mde = new/MapDataExtractor()


The default settings will analyze your project to automatically extract any atoms that have been used in included map files, and will exclude any types listed in the project's Object Tree Hidden Paths preference. You can also specify your own list of types to include and/or exclude.

The generated project contains only a single DM code file--which holds just the visual data of the included atoms--and a precompiled RSC file.

Ah, I'm sorry. Look's like I've been mistaken. I had map with one turf on top of another and it didn't work, but when I deleted one of them, it started working. I assumed MDE doesn't work when there are two turfs in the same location.
Just investigated your library again and I know circumstances when it won't work. For example try to place this mob on your demo's map:
mob
    AI
        New()
            ..()
            src.AI()

        proc
            AI()
                while(src)
                    sleep(50)

If you do this, your library won't ever finish and will just stop at line:
var/datum/D = new path(lab) //GenerateGraph(list/includeList) proc

As a result, MDE_Map_Project folder and the new .dm file won't be ever created.

Hi Kisioj, can you elaborate? Do you mean that if you place one turf on top of another, the lower turf isn't extracted? I just tested it, and it seems to work properly, so if you could give me more details I would appreciate it.

One workaround would be to specifically tell MDE about that turf type so it can include it. You can both scan the map and manually specify types by passing a list with a null element first, followed by whatever types you want to manually include:
var/MapDataExtractor/mde = new/MapDataExtractor(whitelist = list(null, /turf/OtherType, /turf/AnotherType))


The included Demo.dm has some more information.

Do you mean something like:
CustomDatum
    parent_type = /obj
    icon = 'LawnChair.dmi'


Thanks for pointing it out, it slipped my mind. I can add support for it, but it might be awhile before I get around to it.

If you want to do it yourself, you just have to add it to the list (like you did) and define it's default value in IsDefault():
        IsDefault(list/child, list/parent, attribute)

            // Special case for parent_type
            if(attribute == "parent_type")
                // Built-in parent_types
                if( (child["type"] == /obj && child["parent_type"] == /atom/movable) \
                 || (child["type"] == /mob && child["parent_type"] == /atom/movable) \
                 || (child["type"] == /area && child["parent_type"] == /atom) \
                 || (child["type"] == /turf && child["parent_type"] == /atom))
                    return 1

                // Custom parent_types
                if(GetPathParent("[child["type"]]") == "[child["parent_type"]]")
                    return 1
                else
                    return 0

            // ... rest of the process as-is

This seems like a very useful tool. I'll probably end up needing it in the near-future..

Though, I notice it doesn't work with special datums. I decided to go into the code and add parent_type to the list of saved vars, but that saves it for EVERYTHING.. XD
Just figured you should know..
