Background

A couple of months ago I set out to find a simple find and replace tool that I could use when rolling out my projects. For ex. to change various settings in config files to support dev/qa/prod environment.

I was looking for something that would have the following features:
  1. Simple UI to make sure that find/replace does what I need it to
  2. Command line to run find/replace using batch file.


There are many tools available, but they all have the following major issues:
  • Out of date, no updates support for at least a year
for ex. http://www.divlocsoft.com/
  • Bad documentation if any. Many apps mentions that they have command line support, but to find out how it works takes too much effort.
  • Too many features. I just need to type in a couple of fields and click on Run, not to learn a new language.
for ex.
http://www.powergrep.com/
grep/sed variants in windows
  • No access to code. Many tools have 90% of what I need, but if I need just a bit more (support for multi-line) - there is not much I can do.

So I wrote a simple tool to use in my own projects and wanted to share it with others.
