Syntactic coloring in the Monaco editor (Monarch), "@popall" when a new line appears

Question

I am currently writing a syntax shortcut for the Monaco editor using Monarch .

I use statesto work with tokens differently depending on where they are in the string.

What I would like to do is states when I reach the end of the line , since all the lines are independent. @popall

Right now, the only way I've found is to add conditions at the end of all my rules, something like this:

[/\}/, {cases: {'@eos':{token: 'keyword', next:'@popall'},
                        '@default':{token: 'keyword', next:'@pop'}}}],

which is really redundant, obviously, since my 50+ rules have this case.

What is the clean way to do this?
