parse error

It seems that Add method with INTO is not valid for rchef parser like line 28 or 29.

After replacing into with to, the parser raises [line 71] syntax error: expected IDENTIFIER, found NEWLINE.

You need to change into to to as you already discovered. However you also cant end your file with a newline. This is the second error you see and not present in the version on github.

programs/tokens.chef is not mine but this repo's. Anyway, one of original author's sample codes ends with a newline.

• https://dangermouse.net/esoteric/chef_hello.html (ends with <br>)
• https://dangermouse.net/esoteric/chef_fib.html (ends without <br>)

So the rchef interpreter should accept end-of-file line break(s). Otherwise, it should be documented that they are unacceptable.

Yes, i know. I just wanted to let you know that. I forked this repo, corrected the tokens.chef file there and adjusted it to handle trailing newlines (although in a pretty hacky way).

However the sample texts on the DM website are also not actually conforment to the spec as described on the website and the fib program is also broken. So i would cut the original author here some slack.
