This should be the only function called by ConfigParser according to the python docs. We maintain a stack of real FLOs and delegate readline calls to the FLO on top of the stack. When EOF occurs on the topmost FLO, it is popped off the stack and the next FLO takes over. include= lines found anywhere cause a new FLO to be opened and pushed onto the top of the stack. Finally, we return EOF when the bottom-most (configfile arg to __init__) FLO returns EOF. Very Technical Pseudo Code:: def confpp.readline() [this is called by ConfigParser] open configfile, push on stack while stack has some stuff on it line = readline from file on top of stack pop and continue if line is EOF if line starts with 'include=' then error if file is recursive or duplicate otherwise open file, push on stack continue else return line return EOF R i iÿÿÿÿs \s*include\s*=\s*(?P<url>.*)R s> Error parsing config %s: include must specify file to include.s \s*\[(?P<section>.*)\]t sectionN( t linet lenR R!
