Given a text file with a Python-style indentation structure,
searches the file for a regular expression. It prints matching lines, with
their "parent" lines as context. For example, if input.txt looks like this:
2009-01-01 New Year's Day! No work today. Visit with family. 2009-01-02 Grocery store and library. 2009-01-03 Stay home. 2009-01-04 Back to work. Remember to set an alarm.
ogrep work input.txt will produce the following output:
2009-01-01 New Year's Day! No work today. 2009-01-04 Back to work.
Get the source code:
git clone git://github.com/mbrubeck/outline-grep.git; cd
Debian/Ubuntu users, run:
sudo aptitude install libghc6-regex-posix-dev,
./Setup.lhs configure ./Setup.lhs build sudo ./Setup.lhs install
Or to try the program without building and installing it, just run
./OutlineGrep.lhs in the source directory after installing the Haskell
Platform (or the libghc6-regex-posix-dev package).
