Re: [Pharo-users] #parseMethod:onError: isn't as obvious as expected - is it me?

by Tim Mackinnon

Damn you smalltalkâ¦ you suck me in to little side problemsâ¦. RBParser is actually a lot more flexible than I had realised - and not so difficult to understand for a mere mortalâ¦ It naively seems that (what I still consider a confusingly named method) is quite simple to extend to handle at least medium sized errors just by doing something like: ast := [RBParser parseMethod: source onError: [ :msg :pos :parser | |seqNode errorNode| errorNode := RBParseErrorNode errorMessage: msg value: parser currentToken value printString at: pos. seqNode := parser sequenceNodeClass new. parser step; parseStatements: true into: seqNode. seqNode addNodeFirst: errorNode; yourself ]] onDNU: #body: do: [ nil âHandle non method source fragments"]. NOTE: I did have to add >>#currentToken as a method to RBParser as it doesnât expose very much for the onError blocks, which I think it should to make them a bit more useful.

Teapot already supports conditional routes, maybe using them instead of adding the WS: message would be better.
