Making tilemaps for LOVE?

Is there a way I can use a tile editing program to export a simple 2D array containing tile numbers to place in a map? It seems like every tile editor I use likes to either 64-bit encode map data or put it in an unnecessarily bloated array, containing labels all over.
For example, say that tile 0 is a O and tile 1 is an X, and I want a map like this:
How can I use a tile editor to export a text file like this?
Code: Select all
table = {
{0,1,0}
{1,0,1}
{0,1,0}
}
You wouldn't think it would be that hard, but I can't seem to find a solution to this problem. Does anyone know any way to do this with a tile editor?

tiled uses base64 encoding which is pretty simple to decode, but the gzip compression has been abit more elusive within the lua/love world
mappy on the other hand is a tad bit easier to read, but it seems much more difficult to make it mean something, due to its chunk structure and basicly nill documentation
those are the 2 major ones that seem to come up, and I have not had much experience with other less known programs

Well, how do you unencode base64 encoding? I'm kind of a noob to the more technical bits of programming.

course it doesnt get you far with tiled maps since the data is in both base64 and gzipped

I think you can turn off gzip, though.

or use io.popen... (works on linux/osx... unable to test on windows, sorry)
Code: Select all
file='zippydata.gz'
f=io.popen('cat '..file..' | gunzip')
data=f:read('*a')
f:close()

I thought io.popen works, but I know there are no cat and gunzip on windows. (cat can be replaced by type, but you'd still need gunzip)

io functions work fine in windows but yes you will need gzip which is not a default package of windows like it is on other os's
