0.4.0-dev (updated to 7a847045163feb2339ab40ebe93afe2f1c9ad813)
|
|
completely remove dependency on haskell-src-exts
|
|
improve the error messages a great deal
|
|
fix some trailing whitespace issues in the keyword style functions,
|
|
e.g. extract(day from x), dealing with trailing whitespace on
|
|
the parens was fixed
|
|
improve some cases of parsing chained prefix or postfix operators
|
|
(still some issues here)
|
|
parse schema qualified table names in from clause (thanks to Sönke
|
|
Hahn)
|
|
fix bug where the 'as' was incorrectly optional in a 'with
|
|
expression list item'
|
|
fix bug in set operations where 'all' was assumed as the default
|
|
instead of 'distinct', e.g. 'select * from t union select * from
|
|
u' was parsed to 'select * from t union all select * from u'
|
|
instead of 'select * from t union distinct select * from u'.
|
|
fix corresponding bug where 'distinct' was being pretty printed in
|
|
this case and 'all' was not since the assumed default was the
|
|
wrong way round
|
|
replace Int with Integer in the syntax
|
|
derive Data and Typeable in all the syntax types
|
|
remove support for parsing clauses after the from clause if there
|
|
is no from clause

fix some trailing junk lexing issues with symbols and number
|
|
literals
|
|
fix number literals to accept upper case E
|

change the syntax representation of quantified comparison
|
|
predicates
|
|
support array constructors and subscripting
|
|
support character set literals
|
|
support collate
|
|
change the hardcoded collate keyword in substring and trim to use
|
|
the new collate postfix operator, this also changes the collation
|
|
name to be an identifier instead of a string
|
|
support escape for string literals as a postfix operator
|
|
represent missing setquantifier as a literal default instead of as
|
|
the actual default value (all in select, distinct in set
|
|
operators)
|
|
same for sort directions in order by
|
|
parse schema/whatever qualified ids in various places: identifiers
|
|
(replaces equivalent functionality using '.' operator), function,
|
|
aggregate, window function names, explicit tables and functions in
|
|
from clauses, typenames
|
|
support what appears to be 100% of sql 2003 typename syntax (phew)
|
|
support most multiset operations (missing some predicates only,
|
|
likely to be added before next release)
|
|
support two double quotes in a quoted identifier to represent a
|
|
quote character in the identifier
|
|
implement complete interval literals (fixed the handling of the
|
|
interval qualifier)
