Proposals / Proposed Central Documentation Format
« on: May 21, 2010, 04:53:44 PM »
Anyway, the gist of my thoughts is basically what I did with that SVG explaining tiers. Those who pay attention to elements of design may have noticed that some borders contained a somewhat-cheesy image in the upper-left corner. I would like for several key groups to have such.

Of those in the SVG was a clock. The clock signifies future implications and was purely aesthetic. Same for the question mark, which I would like to change later on. It signifies notes on philosophy. I want another symbol with some kind of yellow and green divided image that will signify a difference between GM and ENIGMA resulting from the system. This is where it gets important: It would be useful to have a method of indexing such, especially the differences, possibly the philosophy and possibly notes on future implications. That way, if anyone pulls an Ism and finds what seems to be some minute difference between ENIGMA and GM, They can check it against that list. Otherwise, they can file a bug report.

Problem is, that requires indexing via something akin to SQL. Perhaps the format could be a simple to parse BBCode-like tagset that represents a div with a particular image in the corner. For example,
[future]This system implies that down the road...[/future] [philosophy]The system was chosen because precedence was given to the idea of...[/philosophy]
[simple=2]This graphic illustrates the system at work assuming that the conditions are such to allow for...[/simple]

Notice a few things. There are no
s. I was thinking the system would be best suited to a well-padded table. Tag [bannergraphic] ends the current row, if there is one, allocating a new row especially for a centered graphic. The example shows SVG. This is negotiable, and may in fact be best left out, though most browsers are capable of displaying them considering that the format is open.
Also, the =2 following the simple. This is to imply that the span/td should span two columns. Otherwise the parser should assume overflow should be done vertically.

This is my proposal for a good HTML-based help format. I wouldn't mind working with it, assuming Gary can whip me up a respectable inline editor, and I know he is beyond capable.

Heh, fuck that.

And yes, I seemed to be avoiding the real problem here and that is a blatant lack of central docs. I'm torn between the love of my life, SVG, and a format that most people can actually work with. Even printing to PDF doesn't really help. Would you care to propose an easily navigable and at least remotely eye-pleasing format? Especially if the program is even moderately pleasant to work with.

Nope. Bitches not marked executable if not so, otherwise opens in archive manager anyway. Even though I just picked Sun Java 6 Runtime.

Those are all just broken after various switches between R3 and 4. R3 supported everything you've named off; I'm waiting for a "good opportunity" to install the new instance system for some of those.

Without doubt, versioning will be easier with any sort of directory/archive based "format." Extensibility will also be increased. Now, each approach has some different problems. I've gradated these here:

Storing as a Directory:
This is a radical approach that will make copying and sharing tedious. Copying a directory makes the kernel iterate file hierarchy, which there doesn't seem to be a good platform at doing. The alternative is to zip the file yourself, which can  be time consuming. The benefit is that the IDE or user can use their own compression scheme, and manipulating resources becomes faster and relatively infallible. Version control would be operable immediately at the push of a button. Selecting the file to load in ENIGMA could be a pain in the ass unless a manifest file is configured: it would just be a directory with an extension; how would ENIGMA know if you just wanted to explore it or if you wanted to explore it?

I would like to propose a solution, part of which I implied in that paragraph. When exploring for a file to open, LGM/the IDE could check for a file called EGMmanifest.egm. If found, it reads it for version, and if the version is sane, it opens it or errors that it is too new/old. Otherwise it just opens the directory. Problem with this is, it would take a lot of work (at least in the APIs with which I am familiar) to specify that behavior when exploring directories. Perhaps Java makes that easier.

That introduces the problem of associating ENIGMA projects with ENIGMA. When you double click a GMK, you get Game Maker. Causing that on Windows/Linux would be a hack at best. For that, I propose that double clicking the .EGM manifest will open the file in ENIGMA. To enable this with mime types, the file could be prefixed with EGM as the first line by standard. Thus, to open their project, users would double click the directory, then double click the manifest. Relatively painless, but somewhat annoying after time, especially with orphaned folder windows.

Storing as a Zip Archive:
This has worked for Java for executables for a long time. Not a lot needs written to a Jar at runtime, if anything, but the functionality is out there. This could make writing slow; the question is whether it would be slower than GM's method of packing everything each and every save. Logically, how could it be? But we've yet to see. Association becomes a real prick on Linux, as Linux doesn't care that the extension is a Jar, it sees the ZIP magic number at the beginning of the file. So Linux users would have to Right Click->Open With->LateralGM. Windows users could just double click though, which is who we're really concerned about not offending with trivial tasks.

Sharing would be fast and easy. Versioning would be kind of a pain in the ass, since the entire thing needs compressed, so you have to wait for that, then the versioning application gets to run on it, so you wait for that, then it gets compressed again... Depending on how often that was, I'd be annoyed.

Storing as a PNG-like format:
Basically, this avoids the above problems of file association, and takes a different approach to attaining an extensible format. This would be the most difficult for third-party applets to manipulate, as they would, unlike in the other two methods, need an understanding of a special format. It would also introduce problems for versioning amid all the plugins.

Consider that in the other two methods, versioning was ready either all the time or as soon as the file was automatically unpacked by a completely unrelated third-party compression tool (even though zip is embedded into Java's language, it still has nothing to do with ENIGMA). Here, a third party would actually have to do a little research to figure out how to open the file.

Plugins would need a method not only for writing and reading their extension from the file, but for unpacking to a directory for versioning, which is just an example of a functionality that someone may wish to implement that would be lost because individual plugins would have to be designed around it: If the plugin wasn't built to support versioning or numerous other functionalities brought to the table by other plugins, then it simply never will unless the author of the versioning plugin or X new plugin specifically codes a method for all the extensions. In case the sheer amount of information in that paragraph made my meaning unclear, I am saying that coordination between formats that are entirely plugin-dependent can be difficult for a new, unrelated plugin.

Also, the "reading" part of this format is likely to get messy due to Ism having no way of knowing (as far as I can tell) how they (plugin/extension programmers, though they don't exist) label their extensions to the format. Not to mention that the order of plugin loading is  likely to change from instance to instance of installed versions, so Ism can't just iterate the plugins asking if this is their work: they could be called prematurely. Basically, Ism would have to make calls to each plugin who has registered itself as a format editor to ask, "Is this your doing? If so, undo it." These methods would all be called (until one fessed up to it) on every extension.

luis, flexaplex:
Mark decided he'd take a different approach to the woeful inadequacy of computers' floating point capabilities. While it is true that most languages cannot correctly compare fifths/tenths added together (it is a repeating decimal in binary and therefore can not be represented in a single string of bits of any size), or that sin(pi) == 0 (it's actually 1.2246063538223773e-16), Mark decided that GM should have that capability. That being the case, he made his comparison operators not compare the entire double.

If GM evaluates 1.0000000000001 > 1 as false, Mark is an idiot. ENIGMA will evaluate 1.0000000000001 > 1 and 1.000000000000001 > 1 as true, 1.0000000000000001 > 1 as false. This is because 1.0000000000000001 is simply outside the precision of a floating point value. In actuality, both ENIGMA and GM will store more bits of precision than they check, which is all the solution really needs at this point.

Because of this, I was going to replicate the behavior in ENIGMA by casting to float before comparisons. IEEE tells us that this isn't as simple as just chopping off a large part of the significand, since doubles implement larger exponents as well. But I'm assuming FPUs have a special path just for the occasion.

Scratch that. As it happens, sin(180*pi/180) = 1.2246063538223773e-16.

GM implemented a threshold for such in its == operators. I guess ENIGMA will have to do the same. Morbidly disappointing, really.

Well, mod is easily fixed by--and this needs done soon anyway--creating a file of syntax quirks and in it placing #define mod %. I will do that soon enough; but it won't work for everything because the syntax checker doesn't actually unroll macros yet, even though everything else does.

I'm not sure what's causing your other bugs, Ism, if they are bugs at all. We'll check the outputted C++ next we talk.

I thought it would be Google's right to release their work into the public domain if they get the patent. *shrug*

Serp's really been pushing ( <-- pun ) the idea of switching to git. But I prefer SVN due to the fact that I find SourceForge less likely to go down and I prefer the history of my files be immutable; even when the file is deleted in later revisions.

Retro: All my makefiles use *.o to quickly link. The link target is depended on by Windows' and Linux' targets. The assumption is that you're using one of those. I separated it to avoid reprinting all its dependencies.
