LALR Parser Compiler

v0.3.2

Hydrocarbon is a LALR and GLALR parser compiler that uses a self hosted, custom grammar that is inspired by Backus-Naur syntax.

You can review the Hydrocarbon grammar definition in ./source/grammars/hcg. The definition is split across 5 files starting with hcg.hcg.

The primary reason this exists is to provide a flexible parser compiler to handle the parsing demands of the CandleFW libraries Wick, JS, and CSS. It provides a way to rapidly define new syntax and compile grammars of different languages into one meta-parser.

Compile

compile <hydrocarbon_grammar_file>

Compiles a JavaScript parser from a HydroCarbon grammar file

Output Path

-o, --output <path> Optional output location. Defaults to current directory. --statesout, Output a *.hcs file.

States File

[-s | --states] <states>
Use a *.hcs file from a previous compilation instead of a compiling the grammar file.

Environment File

[-e | --env] <path>
Optional JavaScript file containing parsing environment information.

Mount

[-m | --mount]
Mounts the compiled parser in the current NodeJS context and allows interactive parsing of command line input.

Grammar Name

[-n | --name] <output_name>, The name to give to the output file. Defaults to the name of the grammar file.

Skip Output

[-d | --no-out]
Skip writing to file.

Compress

[-c |--compress ] Minify output file.

Unattended Compilation

[-u |--unattended ]
Do not wait for user input. Exit to console when compilation is complete. Quits on errors.

Generated File Type

[-t |--type] <type> Type of file to output.The type can be: "mjs" - ( * .mjs) A module file for use with the modern ES2016 module syntax. "cjs" - ( * .c.js) A CommonJS module for use with NodeJS and other consumers of CommonJS. "js" - ( * .js)[Default] A regular JavaScript file that can be embedded in HTML.The parser will be available as a global value.The name of the global object will be same as the output file name.

Parser Type

--parser <parser> The type of compiler that hydrocarbon will create. Select from lalr1 and earling
