# at the top of the file
from gtirb_rewriting.patches import CallPatch

# in a Pass's begin_module callback:
exit_sym = context.get_or_insert_extern_symbol('exit', 'libc.so.6')
context.register_insert(..., CallPatch(exit_sym, [42]))

I just run this program:

import argparse
import logging

import gtirb
import gtirb_functions

from gtirb_rewriting import *
from gtirb_rewriting.patches import CallPatch

class NopPass(Pass):
    def begin_module(self, module, functions, context):
        exit_sym = context.get_or_insert_extern_symbol('exit', 'libc.so.6')
        context.register_insert(..., CallPatch(exit_sym, [42]))

def main():
    logging.basicConfig(format="%(message)s")

    ap = argparse.ArgumentParser()
    ap.add_argument("infile")
    ap.add_argument("outfile")
    ap.add_argument("--verbose", action="store_true")
    args = ap.parse_args()

    if args.verbose:
        logging.getLogger("gtirb_rewriting").setLevel(logging.DEBUG)

    ir = gtirb.IR.load_protobuf(args.infile)

    pass_man = PassManager()
    pass_man.add(NopPass())
    pass_man.run(ir)

    ir.save_protobuf(args.outfile)

if __name__ == "__main__":
    main()

but I get errors:

Can you write full python code in an examples folder for all Common Tasks & Questions?
