Parser
A parser turns its input (often text in form of a file) into a more advantageous representation (usually a certain data structure in memory) to perform a specific task.
Common examples include:
- parsers for markup languages (e.g. HTML/Markdown etc)
- parsers for data-serialization formats (e.g. JSON/XML/YAML etc)
- parsers used as part of/in conjunction with a compiler (in this case, the parser consumes the tokenized input emitted by the Lexer and ultimately feeds the resulting parse tree/concrete syntax tree into the compiler)

https://github.com/elkard/tkom_parserandinvariantsoptimizer
Project for the ‘Compilation Techniques’ course on 6th semester. Firstly I defined the grammar of my own language. Then I implemented a lexical analyzer, parser and semantic analyzer. These modules generate the syntax tree of the given source code (or display the error line with the description of the error). If the source code is correct, the next module (the optimizer) optimizes the syntax tree by detecting invariants in the loops and moving them before the loop. After optimization, the app generates new code based on the modified syntax tree.
