I've basically terminated te feature-completion of the BSD-licensed grep
from OpenBSD. It means, that I've accomplished the following tasks:
- Implement --label
- Implement --null
- Implement --color / --colour
- Implement -D / --devices
- Implement -H / --with-filename
- Implement -J / --bz2decompress
- Implement -d / --directories
- Implement -m / --max-count
- Implement -o / --only-matching
- Add --help
- Eliminate warnings
- style(9) cleanup
I've made some preliminary tests with the fgrep and normal grep
behaviour and it seems that they can achieve the same speed.
What remains is to do more test about the performance and the
compatibility with the GNU version. You can test this version easily by
installing the textproc/bsdgrep port, which creates two symlinks:
bsdgrep points to this version and gnugrep points to the base grep.
Any help and comments are welcome.
P.S.: Acknowledgements are going to Max Khon, who is my mentor in this
program, to Diomidis Spinellis due to the his useful comments and to
Sean C. Farley who worked on this implementation of grep before and
provided some preliminary comments and suggestions before I started
working on this project, and of course, to Google for sponsoring this
piece of work.
