-* **`mutator`** and **`mutator-lvl2`** are collectively the code muatation and code transformation(automatic-refactoring) executables. Currently the automatic code transformations implemented are only limited to adding braces to blocks that are missing it, fixing SwitchStmts with adding a default clause if missing and breaks, swapping the RHS and LHS when the RHS is a constant and adding `else` if an if-else is missing one. The mutation is only limited to statement and condition tagging for the time-being.<br/>

### Dev Plans
* Branch a release candidate for `mutator-lvl0`, then start writing the unit tests. This might take a while, since I will try to find testers and code reviewers. If you are willing to help with testing, Email me at `thabogre@gmail.com`. Please set the subject to `mutator-lvl0 test` so I wouldnt miss it. I'll do the unit tests and reviews myself if I dont manage to find volunteers for that. while it's far from ideal, it's better than nothing.

## Building and Running
### Building
+
To build the project, you need to have the LLVM libraries 4.0 and up. The project can not be built with LLVM 3.8 or lower. The latest tested is LLVM trunk:292415.<br/>
Here Are the build options:<br/>
+
* Running `make` will build the default target which is `all`. This will build all three executables, without support for coverage instrumentation.<br/>
* Running `make target-name` will only build the target. So for example, if you are only interested in building the Misra-C rule checker you can run `make mutator-lvl0`.<br/>
* The makefile option `CXX` tells the makefile which compiler to use. The default value is `clang++`. Currently the only two supported values are `clang++` and `g++`.<br/>

### Running
+
To run any of the tree executables, just give a filename or a whitespace-separated list of files. The executables will print out the results to stdout.<br/>
To run the executables with the mutator UI, you can use `mutator.sh`. For a list of available options, you can type `./mutator.sh -h`.<br/>
+
* `-h, --help` prints out the help.<br/>
* `-f, --file` tells mutator to run the commands from the file.<br/>

* SysHeader, will let the executable know that you wish the checks to run through system headers as well. Off by default.<br/>
* MainOnly, will only pusblish check results for matches residing in the main file,i.e. the current TU(Translation Unit).<br/>
* MisraC2004,MisraC2012,C2,C3 will let the executable know which Misra guidelines you want the source to be checked against. currently only supports MisraC2004 or C2.<br/>
#### Note
+
If you are running the executables using `mutator.sh` you don't need to read this note through. if you are running the executable directly however, then you have to pass groups of arguments in a specific order otherwise the executable won't be able to recognize the options and will throw errors.
