[TxMt] Re: Symbol list & Language grammar

[Sean T Allen]

I'm trying to work an issue out...  

It's a smalltalk grammar for redline smalltalk.

method start with either + or - to indicate class or instance

then all of the following are examples of valid smalltalk methods

string
at:
at:put:

textually those would be something like

- string

- at: anIndex

- at: anIndex put: aValue

The current rule I have to match that is:

method_definition = {
begin = '^-|\+\s';
end = '$';
patterns = (
{ match = '((\w+:?)(\s*\w+)?)';
captures = {
2 = { name = 'entity.name.function.instance.smalltalk'; };
3 = { name = 'variable.parameter.method.smalltalk'; };
};
},
{ include = '#language_elements'; },
);
};


The problem really are ones like

at:put:

Keyword methods with more than a single keyword.

Textmate sees it not as  

at:put:

But at: & put:

Highlighting works great but the naming isn't correct.

Can I mark

at: anIndex put: aValue

as the function
then further say anIndex and aValue are method parameters?

then transforming into just at:put:

If that is a reasonable approach. What is the best way to match the variable number of keywords as a single run?
I can get the one at a time in the above approach but I can't figure out a way to match all at once and still mark the individual method parameters.
