gt -- grammar tool Generate OCamllex and OCamlyacc files from a single grammar file. JJ Meyer, Aaron Stump, with contributions from Vilhelm Sjoeberg. Compilation Instructions: This part is not needed unless you created a function with mlcf or an mlcf file was deleted/broken (eg. dump_mlcf_*). We are assuming the user is in "gt/" directory: make clean make make update Assuming you are in "gt/src" directory: The usage of gt is shown below. Below, file is referring to a path of a parseable grammar file. First, from a terminal, navigate to gt/src/. Then execute the following commands. make clean make ./gt file make emitted The command "make clean" will remove all of the compiled OCaml files. The next command "make" will compile gt and generate a file called gt, the grammar tool that will generate a parser from a grammar definition. To use gt use the command "./gt file" where file is a path to a grammar file. Now that gt has generated all of the necessary files use the command "make emitted" to compile your parser. Once this has been done a parser with the same name as the grammar name in the corresponding grammar file has been created. Below is how to use the generated parser. ./grammar_name [options] <file> The options are: -p Reprints the contents of <file> to <file>pp.txt. Without this option the contents are printed to the terminal. -a Prints a text view of <file>'s AST to <file>ast.txt. -g Outputs a Graphviz file named <file>gviz.dot that contains a visual representation of <file>'s syntax tree. -help Shows this.
