general parsing library comparison

[unhammer]

(Sorry that it's not quite the right place to post this, but org's don't have issues and this repo said "parsing")

There's a nice perf comparison of parsing libs at https://gitlab.com/FinnBender/haskell-parsing-benchmarks – would it make sense to incorporate such tests in a repo here? (Or even just import it wholesale as a first step so it gets visibility? @Fybe may want to chime in )

@unhammer Thank you for recommending my repo! I'd be happy to make the changes wanted, to have my repo included here.

However from briefly looking around, I think my benchmark is fundamentally unsuited to be included. Most benchmarks here seem to measure basic operations, so that if you know the approximate distribution of operations performed, you can have an educated guess for which library will perform best.

Meanwhile, I am measuring performance for one grammar. So you can only make ballpark statements like "uu-parsinglib and parsec seem to be a poor choice, if performance is important".
