The C/C++ parser module generated by AnaGram from your description can be compiled on virtually any platform. By incorporating the parser into a DLL, you can even use it in Delphi or Visual Basic programs. About AnaGram 2.01: AnaGram 2.01runs on Win32 platforms. AnaGram generates ANSI compatib...
GNU Bison is a general-purpose parser generator that converts an annotated context-free grammar into a deterministic LR or generalized LR (GLR) parser employing LALR(1) parser tables. Bison can also generate IELR(1) or canonical LR(1) parser tables. Once you are proficient with Bison, you...

Racc is an LALR(1) parser generator. It is written in Ruby itself, and generates Ruby program. Requirement¶↑ * Ruby 2.5 or later. Installation¶↑ gem install: $ gem install racc Testing Racc¶↑ Racc comes with simple calculator. To compile this, on shell: $ racc -o calc calc...
The build scripts use python to embed the parser template into the program. Running pomelo pomelo [options] -h -c <syntax file> Options: --syntax: Writes a syntax file to stdout after parsing, generated from the internal syntax representation. Used to test the syntax parser frontend. --...
Use code binds a function to an action by name at run-time. The action function is accepts the data on the parser's stack matching the right-hand side of the production and returns the data that will be stored in the stack, in place of the right-hand side elements, with the left-ha...
gsi -e "(include \"lalr.scm\")" paren-depth.scm < input.c and this shell command generates and runs the parser on a series of input files: for x in gambc-v4_2_5/lib/[cmos]*.c; do echo $x gsi -e "(include \"lalr.scm\")" paren-depth.scm < $x ...

A modern AST grammar lexer/parser generator written in C. Neoast can take arbitrary lexing and grammar rules and generate a scanner and parsing table. Unlike Bison/Flex, neoast does not generate the scanner and parsing runtime for each input, it uses the same algorithm and links a static ...
