How to parse a .config file

[brian behnia]

Hello all,

I have a summer internship and am creating a GUI in QT to generate a configuration file for a very complicated blind deconvolution process. My job is rather easy, though.

I have created the GUI and made an event for saving the parameters in to a .txt config file. Now, though, I need to be able to load a configuration file and set all the fields and checkboxes based on the values in the file.

I need to parse it in in C++. I haven't programmed c++ in a long time.

The file looks like:

############### ############### ######
# COMMENTS
############### ############### ######
VARIABLE: VALUE

############### ############### ######
# COMMENTS 2
############### ############### ######
VARIABLE2: VALUE2

These values can be stored as chars by my program.

I basically need to store each line in a string or cstring, throw out lines with a '#' in the front, and then split the "VARIABLE:VALUE " in to two separate strings using the : as a delimiter.

Once I have the two strings, I was just thinking of doing a bunch of if statements to match the string 1 VARIABLE to the var in my gui (named the same thing) and then assign the value with string2.

I could really use some help. I'm going to call my programming buddies tonight but I should have had this done already.

Much obliged,
Bri

I would do something like use getline ro read lines from files. Put those lines into a stringstream and use that to read out (using getline again) parameters 1 at a time delimited by :. If the first character of the first parameter is a # then its a comment otherwise the first parameter read is the variable name and the second parameter read is its value.

This assumes none of the values or variable names contain :
