Build Status

Easyfix is a tool for making easy fixes to text files, enabling simple large-scale cleanups of your code, documentation, or any other files.

Unlike other language-specific frameworks, Easyfix is language-agnostic and is thus applicable to type of files, such as shell scripts, documentation, etc. Of course, it can also be used with C++ and Java code, but since it is language-agnostic, it does not parse the files and hence cannot do language-semantics-aware editing.

At its core, Easyfix is a simple in-place rewriter using regular expressions, which may be easier and faster to use for simple cleanups than getting out the heavy machinery.

It also provides a very simple-to-use testing mechanism so you can verify that your cleanup will affect exactly what you want to change and neither over-apply nor under-apply the rewrite, before running the modification script on a large tree of files.


To use easyfix, simply create two files:

  • <your_file>.sh to make the changes, and
  • <your_file> to verify the changes

See the examples directory for samples of both types of files.
