As for syntax I found this in the file "process_init.py"
Python:
from module_info import *
from process_operations import *
import os
print "Initializing..."
try:
os.remove(export_dir + 'tag_uses.txt')
except:
a = []
try:
os.remove(export_dir + 'quick_strings.txt')
except:
a = []
try:
os.remove(export_dir + 'variables.txt')
except:
a = []
try:
os.remove(export_dir + 'variable_uses.txt')
except:
a = []
variables = []
variable_uses = []
try:
file = open("variables.txt","r")
var_list = file.readlines()
file.close()
for v in var_list:
vv = string.strip(v)
if vv:
variables.append(vv)
variable_uses.append(int(1))
save_variables(export_dir, variables, variable_uses)
except:
print "variables.txt not found. Creating new variables.txt file"
As I can understand this 4 files should be deleted before major release: tag_uses.txt, quick_strings.txt, variables.txt, variable_uses.txt. They will be newly generated. Also WRECK doesn't recognise caps letters and it's adding new variables (with low letters) to variables.txt. So you shouldn't use caps in the global variables.
Someone more experienced can reveal more information, I think.
