Question

I have C++ project (VS2005) which includes header file with version number in #define directive. Now I need to include exactly the same number in twin C# project. What is th

Answer 1

I wrote a python script that converts #define FOO "bar" into something usable in C# and I'm using it in a pre-build step in my C# project. It works.

# translate the #defines in messages.h file into consts in MessagesDotH.cs

import re
import os
import stat

def convert_h_to_cs(fin, fout):
    for line in fin:
        m = re.match(r"^#define (.*) \"(.*)\"", line)
        if m != None:
            if m.group() != None:
                fout.write( "public const string " \
                + m.group(1) \
                + " = \"" \
                + m.group(2) \
                + "\";\n" )
        if re.match(r"^//", line) != None:
            fout.write(line)

fin = open ('..\common_cpp\messages.h')
fout = open ('..\user_setup\MessagesDotH.cs.tmp','w')

fout.write( 'using System;\n' )
fout.write( 'namespace xrisk { class MessagesDotH {\n' )

convert_h_to_cs(fin, fout)

fout.write( '}}' )

fout.close()

s1 = open('..\user_setup\MessagesDotH.cs.tmp').read()

s2 = open('..\user_setup\MessagesDotH.cs').read()

if s1 != s2:
    os.chmod('..\user_setup\MessagesDotH.cs', stat.S_IWRITE)
    print 'deleting old MessagesDotH.cs'
    os.remove('..\user_setup\MessagesDotH.cs')
    print 'remaming tmp to MessagesDotH.cs'
    os.rename('..\user_setup\MessagesDotH.cs.tmp','..\user_setup\MessagesDotH.cs')
else:
    print 'no differences.  using same MessagesDotH.cs'
