A grammar describes the syntax of a programming language, and might be defined in Backus-Naur form (BNF). A lexer performs lexical analysis, turning text into tokens. A parser takes tokens and builds a data structure like an abstract syntax tree (AST). The parser is concerned with context: does the sequence of tokens fit the grammar? A compiler is a combined lexer and parser, built for a specific grammar.
ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files.

The rust code in the .lalrpop files are still on rust 2015 and need to be manually updated since cargo fix won't work on those files.
We should also update the generated code to emit 2018 idiomatic code (see #2018 )

I'm using link-grammar-5.3.15.
This one didn't work for me:
https://github.com/opencog/link-grammar/blob/master/bindings/java/org/linkgrammar/LinkGrammar.java#L43
Even when I added /usr/local/lib to jvm props:
java.lang.UnsatisfiedLinkError: no liblink-grammar in java.library.path
I fixed it by replacing that line into:
System.load("/usr/local/lib/liblink-grammar-java.so")

The Hunspell binding for nodejs that exposes as much of hunspell as possible and also adds new features. Hunspell is a first class spellcheck library used by Google, Apple, and Mozilla.
Perhaps it should be opt-in, but most usage would expect a BOM is ignored.
