Outline Grep

============

Given a text file with a Python-style indentation structure, `ogrep`

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.

then `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.

Installation

------------

Get the source code: `git clone git://github.com/mbrubeck/outline-grep.git; cd

outline-grep`

OS X or Windows users, download the [Haskell Platform][1].  Then type `cabal

install`.

[1]: http://hackage.haskell.org/platform/

Debian/Ubuntu users, run: `sudo apt install libghc-regex-posix-dev`,

then run:

    ./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).
