Auto edit strategy with ID's [message #1074022] Fri, 26 July 2013 00:20 Go to next message

I need to implement an auto edit strategy which should have ID's in its context. My DSL has something like this:

'function' name=ID ':'
FunctionBody
'end'


So, I need to check when the user typed "function", followed by an ID and a colon, and only then auto complete the "end" keyword. Is it possible?

I looked into the DefaultAutoEditStrategyProvider, but it only seemed capable of autoediting predetermined tokens. Also, SingleLineTerminalsStrategy and MultiLineTerminalsEditStrategy seemed to ignore strategies triggered by a keyword. Is there a way around?

Hi,

the provider is just for registering the strategies to be used. You can add any IAutoEditStrategy (have a look at their implementations).

However, I would use a simpler approach:

1. provide a template for a function.
2. the auto edit strategy inserts end already when "function" is typed. This may even be achieved using the multilineTerminals in the provider (not tested).

Thank you for your suggestion, I'm trying templates now. They're probably better for my case.
As for inserting function/end with the multilineTerminals, it is not possible. It ignores auto edit rules containing keywords, I'm not sure why.
