JSON writer

[iamgreaser]

This should theoretically be easier than the JSON parser, as instead of having to read char by char like it's nineteen-ninety-LL(1), a bit of printf() should do the trick... after discerning the types, of course.

Printing strings might be a bit tricky, as you need to deal with the escape codes, and we will almost certainly be using lua_tolstring to get them (\u0000 anyone?). Here it's probably best to read the string char-by-char, and feed the stuff into a switch statement.

We won't allow people to use a combination of numbers and strings for keys used in Lua lists. If there are numbers, it's an [ array ]. If there are strings, it's an { object }. If there are both, spew a lua_error(L, "THIS ISN'T RUBY"). If there are neither, it's an { object }, which from the Lua end is the same thing as an [ array ] so it doesn't matter - if it needs to be an [ array ], it will become an [ array ] once it has more stuff in it.

Make sure you have a tab-count variable in the json_write_object function (or whatever it's called). Yes, we will be using hard tabs, because soft tabs take up more room on the disk. Plus, soft tabs suck ass.

See http://json.org/ for more information on the syntax.

BTW Lua tables are actually created as arrays + hash tables if they contain string and integer keys, see http://www.tecgraf.puc-rio.br/~lhf/ftp/doc/hopl.pdf

Why not use a 3rd party library? I know you'd prefer that everything was written in-house, but there is still quite a lot to do yet, so it seems a bit of a waste spending unnecessary time on stuff like this.

2ab3e8bad1e32b3d05477948354ca58 doesn't do "THIS ISN'T RUBY" checking and doesn't indent, but I think it's close enough to close this.
