[CSC 415] Splitting Source Files

[Andrew J. Pounds]

I know that several of you are working on code and working on splitting 
up code.  Here is something I have used before from the UNIX POWER TOOLS 
for breaking up C code into individual source files.

example, adapted from AT&T's UNIX / User's Reference Manual/ :

    % |
    *
    csplit -s -k -f routine. prog.c '%main(%' '/^}/+1' '{99}'*
    |
      

The idea is that the file / prog.c/ contains a group of C routines, and 
we want to place each one in a separate file (/ routine.00/ , / 
routine.01/ , etc.). The first pattern uses | %| because we want to 
discard anything before / main/ . The next argument says, "Look for a 
closing brace at the beginning of a line (the conventional end of a 
routine) and split on the following line (the assumed beginning of the 
next routine)." Repeat this split up to 99 times, using / -k/ to 
preserve the created files. [4]

    [4] In this case, the repeat can actually occur only 98 times, since
    we've already specified two arguments and the maximum number is 100.

If you want to do Fortran, then there is a program called fsplit that I 
have installed on zeus.  (type man fsplit)
