No EOL on last line of file

[timofurrer]

I have some grammer with does something like this:

_NEWLINE: ( /\r\n[\t ]*/ | /\n[\t ]*/ | COMMENT )+
_INDENT: "<INDENT>"
_DEDENT: "<DEDENT>"

foo_compound_stmt: "FOO _NEWLINE (_INDENT bar_stmt+ _DEDENT)?
bar_stmt: "BAR" STRING_NO_WS _NEWLINE

And a code sample might look like this:

FOO
    BAR something

This work perfectly fine unless the BAR something is the last line in the file without an EOL character at the end. This happens if the file is in dos format and saved under Windows ...
In this case a _NEWLINE is expected so that _DEDENT matches.

Do you have any solution for this problem?

The quick and easy solution is to add '\n' to the input.

There is a plan to add an EOF symbol to Lark for conceptual completeness, but I think it's not necessary for your use-case.

That's what I ended up doing.

Is this coming any time soon?

Probably not, since there are many other features that are more important.
