I have a huge binary, containing multiple json documents. Is there a way to parse them using jason (or any other json-parser) into a list? eg, make the result of Jason.decode("{}{}") equivalent to Jason.decode("[{},{}]")?

You asked specifically for using a parser to do it, but I’m not aware of any that can do that. You probably know better than I how to work with binaries and charlists, but anyway I would use something like this: defmodule Test do def enlist_json(a), do: enlist(a, 0, "") def enlist(" " <> t, n, …

Yeah, I went this route as well (though splitting the blob into many strings I Enum.map/2 over), but it annoys me, that I have to do pretty much the same thing the parser does anyway (counting parens that are not in a string). Id be happy with something that would roughly do this: {:ok, #{}, "{}"} …

@NobbZ Here is my suggestion: defmodule Example do import Jason, only: [decode: 1] @doc """ Example results: > Example.sample("{}") {:ok, %{}} > Example.sample("{}{") {:error, %Jason.DecodeError{data: "[{},{", position: 5, token: nil}} > Example.sample("{}{}"…

Ah I see what you mean. Discourse uses highlight.js, so changes would need to be made there and then Discourse should pick the new version :slight_smile: https://github.com/highlightjs/highlight.js/blob/master/src/languages/elixir.js @knewter is the author, perhaps he could help?

Are you able to find a way to reliably split the separate documents by newline in the string blob? Replacing "}{" with "}\n{" might work depending on the input data (but is sadly likely very fragile solution). If you manage to achieve separation then just parsing the JSON documents line by line sho…

Have you looked at Jaxon? Seems like it might do what you want.
