A WIP parser combinator library in Gleam without any dependencies. You can just copy-paste it into your project and use it.
In future, this will be added as a package to hex.pm.
let is_space = fn(c) { c == " " }
let non = fn(f, x) { !f(x) }
let is_not_space = non(is_space, _)
let parser =
succeed2(string.append)
|> keep(parse_while(is_not_space))
|> drop(parse_while(is_space))
|> keep(parse_while(is_not_space))
run(make_input("Hello world"), parser)
|> result.unwrap("")Running nix develop will create a shell with gleam and erlang installed.
A huge thanks to Tsoding's parcoom library and Hayleigh's gleam-string-parser whose libraries this one is based on.
