olaf 2004/08/02 07:45:35 PDT Modified files: src/compiler98 MkSyntax.hs Parse.hs SyntaxPos.hs Log: Completed modification of parser etc to handle extended positions correctly. Surely some cases have been missed, which will be noticed in some time as bugs. Note that the tricky problems mentioned last time (see copy below) still exist. Also, positions of types have been left unchanged. These positions do not appear in error messages and there is again a problem of missing position information: a TypeCon has a position for the type constructor, but not the whole type. Note that the type constructor may actually be positioned between the arguments (->). Some tricky things not yet solved: - some constructs may include optional semicolons or curly brackets, e.g. do { x <- myRead; putStr x; } these are currently not included in the position, so the do expression ends at the last "x". - the syntax does not include enough positions to give positions to everything. E.g. now the position of a function declaration DeclFun describes the full declaration, there is no position for the function variable itself. - some syntactic constructs are immediately desugared, for example list comprehensions; now every component of the translation gets the position of the full list comprehension. This makes it easy to map parts of the syntax tree to the source code, but impossible to map part of the source code uniquely to the part of the syntax tree that describes it completely. So hat-observe will find it hard to give for a marked list comprehension just the values of the full list comprehension, not intermediate internal values.

malcolm 2004/07/30 08:01:21 PDT Modified files: docs index.html Log: For better compatibility with cpp, and because otherwise there are certain constructs that cannot be expressed, we no longer permit whitespace in a #define between the symbolname and an opening parenthesis, e.g. #define f (f' id) Previously, this was interpreted as a parametrised macro, with arguments in the parens, and no expansion. Now, the space indicates that this is a textual replacement, and the parenthesised expression is in fact the replacement. Revision Changes Path 1.15 +28 -5 cpphs/docs/index.html
