Even the Antlr FAQ mentions that "almost no one uses parser generators to build commercial compilers." * https://github.com/antlr/antlr4/blob/master/doc/faq/general.... * See: "Wha…

Some of the top of my Head: - Antlr (https://github.com/antlr/antlr4/blob/master/doc/javascript-target.md) - PegJS (https://github.com/pegjs/pegjs) - Nearley (https://github.com/ka…

Luckily there are many Parsing Libraries in the JavaScript eco-system, So we won't have to find out if this convoluted approach is worthwhile :) - https://tomassetti.me/parsing-in-…

I develop a parsing library for fun and I don't think that would be an easy or useful interview question. Maybe it makes sense if you assume the input has already been tokenized so…

You can find it At: https://github.com/SAP/chevrotain

I've created a Parsing Toolkit (for JavaScript) which I believe fulfills 7/10 of the requirements described. Chevrotain - https://github.com/SAP/chevrotain The list of features can…

I kept putting of switching from Travis to Circle-CI in one of my open source projects, But when I did get around to it the whole thing went pretty smoothly and easily and I regret…

Thanks. Chevrotain is an LL(K) Parser library, or more precisely SLL(K), It looks up-to K fixed token ahead to choose the next alternative. Because it is just a library to assist i…

If you are looking for an alternative to standard parser generators you may wish to have a peek at Chevrotain. * https://github.com/SAP/chevrotain Instead of using an abstraction o…

Ohm has several impressive features, such as separation of grammar and semantics and incremental parsing capabilities. The base performance however very low, as in two orders of ma…

Have a look at this: https://tomassetti.me/parsing-in-javascript/#chevrotain This is Not exactly a parser generator but an internal JavaScript DSL for writing parsers, but it does …

Maybe this example will help? https://github.com/SAP/chevrotain/blob/master/examples/gramm... It is implemented using a parsing library so the lookaheads are automatically performe…

Perhaps Antlr?

Incremental parsing is indeed amazing for IDE scenarios. But you still have to parse the entire file at least once. For example it takes 15 seconds to parse lodash.js with Ohm (on …

I don't understand the question. I am not familiar with Haskell but from what I understand Pandoc is a group of hand crafted parsers (readers) for markup formats. How does this rel…

Even the creator of Antlr (Terence Parr) Said: "In my experience, almost no one uses parser generators to build commercial compilers." https://github.com/antlr/antlr4/blob/master/d…

It did not exactly went away. It is still possible to embed semantics inside an Antlr4 grammar. For example see the Antlr4 EcmaScript grammar sample: https://github.com/antlr/gramm…

One option would be to use a Parser that supports fault tolerance and error recovery. In hand crafted parsers this error recovery may be added manually (but resulting in a-lot of w…

Ohm is very impressive. Specifically: 1. The separation of Grammar and Semantics. 2. Handling left recursion in a top down (peg) parser. 3. Incremental parsing. I think that the on…

That is a very good question because afaik many(most?) commercial (meaning "serious"...) programing languages are developed using hand crafted recursive decent parsers which usuall…
