What's the difference between "will increase the burden of maintenance" and "people will be able to shoot into their foot"? Apart from the wording? And about "more general than needed": Not according to my researches. The existing hooks cover everything including a full replacement of the Forth interpreter, which is why I actually can implement recognizers as proposed on VFX (and could do the same on SwiftForth, which is probably the next thing I do). Every single hook that went into VFX went there, because one particular customer or implementer asked for one particular, limited-scope extension of the interpreter. And it grew to exactly the same "everything is possible" situation we have with recognizers. With the exception that each hook has its own special-purpose task and limitation, with the exception of the "replace the entire interpreter"-hook. The same is true for SwiftForth. Forth Inc. did not add as many hooks, but decided to add the general-purpose "replace everything" hook early on (COMPILING and INTERPRETING are the two deferred words), and by doing so likely muted any further request for special-purpose hooks. We are already in the "here be dragons" country. You make lame excuses that the dragon maybe is only a lizard, or a big bat or so, and someone has lighted a campfire. No, the dragon is already there, hiding behind a bunch of hooks. The only thing the recognizer proposal makes is to standardize these already existing, but wildly incompatible interpreter hooks. And to do that, without taking any of the existing capabilities away, it must be as general as it is now. Or maybe even more general, as SwiftForth's hooks also can replace the BL WORD or PARSE-NAME part of the outer interpreter. We have discussed whether each recognizer should do the parsing itself or leave it to the fixed part of the proposal, and decided for the second: Forth source is words, i.e. blank-separated stuff. The recognizer itself however can know that the addr u it gets is part of the current input buffer (i.e. SOURCE), and it is allowed to manipulate >IN if it recognizes something. -- Bernd Paysan "If you want it done right, you have to do it yourself" net2o ID: kQusJzA;7*?t=uy@X}1GWr!+0qqp_Cn176t4(dQ* http://bernd-paysan.de/
