If you want to build this program yourself, you need to have esy installed and follow these instructions:
$ git clone https://github.com/mikaello/re-ndjson
$ cd re-ndjson
$ esy install
$ esy build
And make _esy/default/store/b/re_ndjson-<hash>/default/executable/ReNdjsonApp.exe available on your $PATH with a name you like. E.g.
$ cp -p _esy/default/store/b/re_ndjson-<hash>/default/executable/ReNdjsonApp.exe ~/bin/ndjson
$ echo "export PATH=\"$HOME/bin:$PATH\"" > ~/.bashrc
The program is written in ReasonML and compiled to native. Feel free to open a PR or issue if you find something that could be better :-)
