Lutin-Interpreter

An interpreter for the basic Lutin script programming language.

Options

You can specify several options to the program. All options are usable together.

• -p prints the parsed program
• -a realizes a static analysis of the programm to detect semantic errors.
• -o optimizes the program
• -e executes the program

Make targets

• make creates the Objects/ folder, where all the .o files are compiled to, and creates a lut executable at the same level as the Makefile
• make clean deletes the Objects/ directory and the generated lut executable.
• make remake cleans and makes the project
• make test compiles the project and launches the tests (in the Tests/ folder)
• make coverage compiles the project, launches the tests, processes the generated coverage data and displays them in firefox if installed

Test coverage

We use the GNU test coverage gcov, with the commands lcov and genhtml.

The file coverage.sh (in folder Tests/) :

• Compiles the project, and creates .gcno files in Objects/
• Sets GCOV_PREFIX and GCOV_PREFIX_STRIPS a coverage folder in the Objects/.
• Launches all tests and creates .gcda files
• Process the information with lcov (based on the .gcda files)
• genhtml generates a nice html, with css, to see the results

Now you just have to open Objects/cov_html/index.html and you see a beautiful interface for test coverage.
