converting bibtex to json

Package Use Questions
1

is there an R package that converts bibtex to json? i tried using refManagR to read in the bib file but got stuck on a common bug found in the bibtex package.

<simpleError in do_read_bib(file, encoding = .Encoding, srcfile): lex fatal error:
input buffer overflow, can't enlarge buffer because scanner uses REJECT
>

<simpleError in do_read_bib(file, encoding = .Encoding, srcfile): lex fatal error:
fatal flex scanner internal error--end of buffer missed
>

There is a new pkg I’ve been working on handlr that might help. By json do you mean citeproc json? or something else?

z <- system.file('extdata/bibtex.bib', package = "handlr")
x <- HandlrClient$new(x = z)
x$read("bibtex")
x$write("citeproc")

Have you tried https://github.com/ropensci/bib2df? Maybe converting the data.frame bib2df gives you to json is a solution for you?
