The TSLCompiler is a remake of the original TSLgenerator, a tool used to generate test cases for reference when writing test code. The reasons behind making this edition comes from the limitations of the TSLgenerator, specifically:

• There are situations when certain keywords are ignored due to precedence in the TSL grammar implemented by the TSLgenerator, with no error messages stating this occured.
• While the source code is available, there are four different codebases depending on the Operating System implementing very identical behavior, making it non-trivial to contribute changes.
• Even if the code base was consolidated into one, most of the code is hard to test automatically due to the over-reliance of static variables, and functions that do not return their results by default.

The TSLCompiler is designed to be a drop-in replacement for the TSLgenerator, honoring all of the original command-line options. However, this will reject TSL files containing syntax that would generally be accepted, albeit ignored by the TSLgenerator. This is achieved by implementing the grammar explicitly through a Lexer and Parser library.

In addition, the TSLCompiler is developed using the principles behind Test Driven Development/Behavior Driven Development to provide confidence in any proposed changes.

Finally, to remain fairly close to the original C implementation of the TSLgenerator, and to reduce memory leaks, this project utilizes C++.

• A C++ Compiler supporting the C++20 standard.
• The Lexer library Flex.
• The Parser library Bison version >= 3.2.
• The Meson Build System.
• Catch2, which can be installed into the project locally using meson via meson wrap install catch2

1. Clone this repository.
2. Make a build directory called build for meson.
3. Run meson setup build, where build is the name of the build directory.
4. Open the build directory, then run meson test to check the status of the codebase via compilation and tests ran.
