The F language can be considered as a reduced version of the Lisp language with some simplifications and modifications. It takes the basic syntax and semantics from Lisp.
To visualize the output of a parser, you should have graphviz utility pre-installed and dot command available in your command-line interface. Run Main.java having a language snippet stored in input.txt. Results will be two files: output.dot that contains an input string in DOT language for the graphviz and output.png.
Example:
In case you prefer to write code in VSC you can use syntax highlighting. /extension contains extension for VSC. You need to add it to .vscode/extensions folder. After that you can write code in .f files.
Please note that this is just syntax highlighting that works at the lexer level and cannot highlight unused variables

Lexical analysis is performed with a help of JFlex utility. To be able to run the program you should firstly generated a Lexer class. To do it you should have JFlex install and configured on your computer.
jflex ./lexer/lisp.flex -d ./src/lexIn case you are not able to run jflex, consider using pre-generated Lexer.java file
