a. Have a scenario, where in my function reads in a file which contains list of c-structures as shown below, reads the file and extracts all the information between { } braces for each structure and store them in arrays.
package whatstruct;
typedef struct packed {
int [4:0] version;
char party;
float parity;
char ccc;
int [7:0] spend;
} party_s;
typedef struct packed {
int [5:0] cod3;
int [1:0] group;
int [51:0] duty;
char calloff;
char selfi;
int [11:0] snap;
int [5:0] longtrip;
int [1:0] whattodo;
int [9:0] sky;
int [7:0] yahoo;
int [5:0] hurrey;
int [3:0] appology;
int [1:0] temp;
int [2:0] iddd;
float dontknow;
} dict_s;
typedef struct packed {
int [4:0] jan;
int [12:0] feb;
int [1:0] mar;
logic mar;
logic april;
} months_c;
typedef struct packed {
var apple;
int mango;
float banana;
int lichi
} fruits_s;
endpackage: whatstruct
b. The functions reads in two parameters, one is the file containing the structures and the second parameter contains list of struct names only from which the lines needs to be extracted. For extracting all the infos between {}, tried some of the examples available as given below.
from Tkinter import *
import subprocess
import shlex
import os
import time
import string
import threading
import sys, argparse
import ttk
import re
import logging
import warnings
import os.path
import gzip
readstructfile = None
filename = None
structnames = None
def readfileanddump(filename, structnames):
readstructfile = open(filename, "r+")
test_str = readstructfile.readlines()
matches = re.finditer(r"{(.*?)}", str(test_str), re.MULTILINE | re.DOTALL)
for matchNum, match in enumerate(matches):
for groupNum in range(0, len(match.groups())):
print (match.group(1))
# for lines in readstructfile:
# print lines
readfileanddump("structpkg.c", all);
c. Was able to extract all the infos between {} and dumpout the infos if the second parameter is provided as "all". But if the second parameter passed is a string containing struct names, only those struct that needs to be extracted. I am unclear how to do that. Is it possible using regexp ? or any other way is better?
Any suggestion is highly helpful !
