- I am submitting the following three programs to the public domain in care
- of the C users group:
-
- DIFF.EXE A file differencer program roughly patterned
- after the UNIX utility of the same name. It
- has UNIX-style output, and uses an interesting
- differencing algorithm, the "recursive longest
- matching sequence" algorithm.
-
- DELTA.EXE A variation of the DIFF utility which generates
- files suitable for passing to the UNIX editor 'ed'
- to generate a new file based on an existing file
- and a delta file. It can be used to effect a very
- primitive source code control system, or as a basis
- for developing a full-featured SCCS.
-
- APPLY.EXE A utility which will apply a delta created using
- DELTA.EXE to a source file. This effectively mimics
- the operation of UNIX ed's script editing.
-
-
- These utilities were all developed under Microsoft OS/2 version 1.0 and 1.1,
- using the MS C version 5.1 compiler. They use no OS/2 specific calls, and
- should be portable to any ANSI standard compiler (and probably even a straight
- K & R compiler with slight modification).
-
- A note to OS/2 users:
-
- These routines use only family API calls, and therfore can be bound
- (using the MS BIND utility) to run under MS-DOS 3.X as well as
- MS-OS/2 1.X.
