The PowderCoder script

This is a topic dedicated to the PowderCoder script me and MasterMind555 have been preparing.
There is a beta version just for now. Made in Python 2.6. (could make in VB soon)
MasterMind555 is doing the element properties and stuff area from where you make the base for powder.h
< powdercoder.tk >
I have been making the other half. The scripting language.
This is the first test release of the interpreter. Be sure to report any bug.
Soon, MasterMind's page will be dedicated to this.
It'll look better and have forums and stuff. I hope.

print 'Hint: use *EXIT to exit the program.'
print ' Boxmein\'s Powder Toy Script Interpreter!'
print 'BETA 0.1 - Need to edit vars by yourself. '
print '(it means any vars inside must be done by self)'

filename= str(raw_input("What is the name of your file ->-> "))
if filename == '*EXIT*' :
exit()

< tab >f = open(filename, 'r')
except IOError:
< tab >print 'File does not exist.'
replacers = [['pressure','partgrid','blockgrid','ewallgrid','r','currentelem','currentpart','then','end','nearbypart','create','createline','kill','nearest','typechange'],
['pv[y/CELL][x/CELL]','pmap[y][x]','bmap[y][x]','emap[y][x]','pmap[y][x]','t','parts[i]','{','}','parts[r>>8]','create_part(-1,x,y,TYPE)','create_line(x1,y1,x2,y2,r,TYPE)','kill_part[i]','nearest_part(CURRENT,TYPE)','part_change_type(TYPE1,X,Y,TYPE2)']]
content = f.read()
content = content.split()
for i in range(0, len(replacers)-1):
< tab > content.replace(replacers[i,0],replacers[i,1])
g = open(filename + '.c', 'w')
g.write('int update_ELEMENTNAME(UPDATE_FUNC_ARGS) {' + content + '}')

" Save as" this in Notepad as "All files (*.*)" and with the name "anyname.py"
Then run it and voila. (For now, finds files within its directory)
Be sure to not forget to replace < tab > with real tabs!
Usage example:
if ( pressure < 100 ) then currentpart .temp = 1000; end else then currentpart .temp = 2; end

Lua now? lol. It's not to be added INTO THE CONSOLE. It's a separate program.

I didn't feel necessary. Maybe if it gets longer.
