I'm writing a python tile map editor. I was using a self designed code to write and parse some files but the code was very confusing, so I switched to JSON for simplicity.
My json file is hand made like this:
{ "Level" :
{
"levelName": "simpleLevel",
"background": [[12, 2,12, 2, 1, 2, 3, 3, 1, 1],
[ 1, 1, 7, 8, 5, 6, 7, 8,12, 3],
[ 1, 3, 1, 3,12,10,10, 1,12,12],
[ 2,12, 0, 4,10, 3,12, 2,12,12],
[12,12, 1, 1,10, 3,12, 2,12, 1],
[12,12,12, 0,10, 2, 1,12, 1,12],
[ 3,12, 3,12, 0, 2, 2,12,12, 3],
[ 1,12, 1,12, 1, 1,12,12, 3,12],
[ 3,12, 0,12,12,12,12,12, 3, 3],
[12, 3, 1, 2, 3,12,12,12, 1,12]],
"foreground": [[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[ 0, 2, 0, 0, 0, 0, 0, 0, 0, 0],
[ 0, 3, 0, 0, 0, 0, 0, 0, 0, 0],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]]
}
}
But, when I use json.dump(self.x, f) my output is in a single line, and when I try to use these parameter sort_keys=True, indent=4, separators=(',', ': ') I get a thousand linefeeds..
I just want something similar with my handmade file because it's easier to read and edit by hand. I could find some solutions to simple arrays but nothing that worked for 2d arrays. Is there a simple answer or should I code myself?
edit:
coded myself (with some help from the web..)
def fwriteKeyVals(data, f, indent=0):
if isinstance(data, list):
f.write( "\n" + " " * indent + "[" )
for i in range(len(data) ):
if ( i == 0):
f.write( "[" )
else:
f.write( " " * indent + " [" )
for j in range(len(data[0])):
f.write( "%3d" % data[i][j] )
f.write( "," ) if j != len(data[0])-1 else (f.write( "]," ) if i != len(data)-1 else f.write( "]" ))
f.write( "\n" ) if i != len(data)-1 else f.write( "]" )
elif isinstance(data, dict):
f.write( "\n" + " " * indent + "{" )
for k, v in data.iteritems():
f.write( "\n" + " " * indent + "\"" + k + "\"" + ": ")
fwriteKeyVals(v, f, indent + 1)
if( data.keys()[-1] != k):
f.write( "," )
f.write( "\n" + " " * indent + "}" )
else:
f.write("\"" + data + "\"")
Usage is:
fwriteKeyVals(x, f)
Where x = json.load(f) and f is the file I've loaded with f = open( map , "wb" ).
Ok, coded myself. Some hacks to print \n instead of real linefeed.
def fwriteKeyVals(data, f, indent=0):
if isinstance(data, list):
try:
gotdata = isinstance(data[0], list)
except IndexError:
gotdata = False
if gotdata:
f.write( "\n" + " " * indent + "[" )
for i in range(len(data) ):
if ( i == 0):
f.write( "[" )
else:
f.write( " " * indent + " [" )
for j in range(len(data[0])):
f.write( "%3d" % data[i][j] )
f.write( "," ) if j != len(data[0])-1 else (f.write( "]," ) if i != len(data)-1 else f.write( "]" ))
f.write( "\n" ) if i != len(data)-1 else f.write( "]" )
else:
try:
gotdata = data[0]
except IndexError:
gotdata = 'False'
if gotdata is not 'False':
f.write( " [" )
for i in range(len(data) ):
if isinstance(data[i], Number):
f.write( "%3d" % data[i] )
else:
dataListLf = data[i].split("\n")
dataToWrite = dataListLf[0]
for line in dataListLf[1:]:
dataToWrite += '\\n'+line
f.write( "\"" + dataToWrite + "\"")
f.write( "," ) if i != len(data)-1 else f.write( "]" )
else:
f.write( " [\"\"]" )
