lalr1

DOI: 10.5281/zenodo.6987396

LALR(1) parser generator library in C++20. Generates either a recursive ascent parser or LALR(1) tables out of a given grammar. Supports parser generation for multiple target languages.

Forked on 30 July 2022 from https://github.com/t-weber/lr1 DOI: 10.5281/zenodo.3965097.

Installation

  • Create the build directory: mkdir build && pushd build.
  • Build the libraries: cmake -DCMAKE_BUILD_TYPE=Release .. && make -j$(($(nproc)/2+1)).
  • Install the libraries: make install.

Examples

Script Compiler

  • After building the libraries (see "Installation" above), run ./script_parsergen from the build directory to create the script compiler's parser component.
  • Re-run cmake -DCMAKE_BUILD_TYPE=Release .. && make -j$(($(nproc)/2+1)) to build the script compiler.
  • Run an example script using ./script_compiler -r ../examples/script_tests/fac.scr.

Expression Parser

  • After building the libraries (see "Installation" above), run ./expr_parsergen from the build directory to create the expression parser.
  • A graph of the LALR(1) closures is written to the file "expr.svg".
  • Re-run cmake -DCMAKE_BUILD_TYPE=Release .. && make -j$(($(nproc)/2+1)) to build the expression parser.
  • Run the expression parser using ./expr_compiler.

Symbolic Differentiation

  • After building the libraries (see "Installation" above), run ./diff_parsergen from the build directory to create the differentiation parser.
  • Re-run cmake -DCMAKE_BUILD_TYPE=Release .. && make -j$(($(nproc)/2+1)) to build the parser.
  • Run the parser using ./diff_compiler.
