Changelog for haskell-src-exts-1.12.0
** 1.12.x 1.11.1 --> 1.12.0 =============== * Move from old [$...| quasi-quote syntax to the new [...| one. The old syntax is still recognized while parsing. * Allow symbols as variables when TypeOperators is enabled. * Rename ExplicitForall in ExplicitForAll, to be consistent with GHC and the Haskell' process. ** 1.11.x 1.10.2 --> 1.11.1 =============== * API change: the fixities field in ParseMode is now of type Maybe [Fixity]. If the field is Nothing the parsing will not try to do any fixity resolution whatsoever, otherwise it behaves as before. * API change, bug fix: The Fixity type contains a QName rather than an Op to name the operator. The operator must match the given QName exactly (i.e., unqualified names only match unqualified names, and qualified names only match qualified names) for applyFixities to perform fixups. * Bug fix: End-of-file inside an OPTIONS pragma no longer loops. ** 1.10.x 1.10.1 --> 1.10.2 =============== * Fix a missing case in the Functor declaration for Decl. Thanks to Malcolm Wallace for the patch! 1.10.0 --> 1.10.1 =============== * Enable the unicode version of DoubleColon (x2237). Thanks to Andr� Sicard-Ram�ez for the patch! 1.9.6 --> 1.10.0 =============== * Ensure that implied extensions are always picked up, not only when using the parseFile* family of functions as previously. * Add the newly devised <%>...</%> syntax to the XmlSyntax support. This causes changes to pretty much everything, including adding a case to the AST which prompts the major version bump. ** 1.9.x 1.9.5 --> 1.9.6 =============== * Fix a bug (#203) where the lexer loops on malformed quasi-quoters. * Fix a bug with pretty-printing RULES pragmas. 1.9.4 --> 1.9.5 =============== * Fix a bug where deriving clauses for GADT-style data declarations were not properly indented. * Pretty-printing patterns is now more accurate in inserting (and not inserting) parentheses when needed. 1.9.3 --> 1.9.4 =============== * Pretty-printer now inserts parentheses in clever places when printing kinds. * Pretty-printing expressions is now far more accurate in inserting (and not inserting) parentheses when needed. * Pretty-printing negative expressions no longer inserts a superfluous space between the - and the expression. 1.9.2 --> 1.9.3 =============== * Constructors for newtype declarations must now have exactly one argument. This is only when using the classic syntax, not with GADT-style syntax. * Fix a bug where preceding commas in tuple sections were counted one too few. 1.9.1 --> 1.9.2 =============== * Fix a bug with pretty-printing lexer tokens. * Fix a bug where non-colon TypeOperators could not be used in prefix mode. 1.9.0 --> 1.9.1 =============== * Export parseFileContentsWithExts from .Exts. 1.8.2 --> 1.9.0 =============== * OptionPragma is renamed to the more descriptive ModulePragma, and adds a constructor AnnModulePragma for handling ANN pragmas preceding module header. * Add instances for Eq/Ord/Data/Typeable for Fixity. * Add 'parseFileWithComments' and 'parseFileContentsWithComments' to L.H.Exts . * More informative error messages when HSX tags are mismatched. ** 1.8.x 1.8.1 --> 1.8.2 =============== * Don't insert redundant parentheses around record constructions and updates. 1.8.0 --> 1.8.1 =============== * Fix three bugs with the handling of ANN. I must have been really tired when implementing that support. 1.7.2 --> 1.8.0 =============== * Add an instance Show Fixity (derived). * Support for the new ANN and INLINE_CONLIKE pragmas. * Export knownExtensions from .Extension. * Remove support for CFILES and INCLUDE pragmas. The support wasn't correct anyway, as it assumed the pragmas appeared at the top of files. As CFILES/INCLUDE pragmas can (and do) appear anywhere, there's no hope to support them in the AST. Better to remove the support altogether. Files with CFILES/INCLUDE pragmas can still be parsed of course, but those pragmas will be handled as comments. * Parsing with ignoreLinePragmas = False now correctly updates the file name. * Allow the whole SPECIALISE/INLINE family of pragmas in instance declarations. The InsInline constructor is removed, and is now represented by InsDecl (InlineSig ...). * Fix a bug with line numbering and quasi quotes, and a similar one with line numbering and CDATA. * Fix a few minor bugs in the exactPrinter. * Fix the strange handling of so called strings in LINE pragmas. ** 1.7.x 1.7.1 --> 1.7.2 =============== * Fixes a bug in lexing LINE pragmas (used when ignoreLinePragmas is set to False). 1.7.0 --> 1.7.1 =============== * UnicodeSyntax now also enables the forall symbol (U+2200). 1.6.1 --> 1.7.0 =============== * Operators defined on the form (a `op` b) c = ... could not be handled by the (annotated) AST, nor the parser. I had to change the definition of the AST node for InfixMatch to allow a list of right-hand subpatterns, i.e. InfixMatch l (Pat l) (Name l) (Pat l) ... has become InfixMatch l (Pat l) (Name l) [Pat l] ... I also had an epiphany and fixed the issue that would arise with exact printing of prefix definitions including parentheses, so that now works too! ** 1.6.x 1.6.0 --> 1.6.1 =============== * UnicodeSyntax now works not only for identifiers, but also for ->, <- and =>, as well as Arrows arrows and kind stars. 1.5.3 --> 1.6.0 =============== * (=~=) turns out to be too general at Functor (for intuitive and not technical reasons), so is specialised to Annotated to closer mirror the original intention. * applyFixities is hoisted to a monad, and now fails on ambiguous infix expressions. ** 1.5.x 1.5.2 --> 1.5.3 =============== * Several small bug fixes in the exact printer, and fail more gracefully if the number of srcInfoPoints doesn't match the needs of the node. 1.5.1 --> 1.5.2 =============== * Fix a bug in the exact printer that made it always print the first token at position (0,0). * In fixing the above, Annotated is now a superclass of ExactP. It was already a superclass in spirit, and nothing can break from this since ExactP is only exported abstractly. 1.5.0 --> 1.5.1 =============== * The pretty printer now introduces parentheses for non-atomic arguments to function application. Note that infix applications are left untouched, no parentheses will be inserted there, as it is assumed that fixities are already properly resolved. * Fix a bug in the pretty printer where view patterns and n+k patterns were not properly parenthesised. 1.4.0 --> 1.5.0 =============== * Add support for acting on LINE pragmas while parsing, i.e. updating the source position according to info given in LINE pragmas. This is done conditionally based on a new flag ignoreLinePragmas in the ParseMode, hence the need to increase the major version. ** 1.4.x 1.3.5 --> 1.4.0 =============== * The AST node for Proc in the simple AST is changed to include a SrcLoc argument, to make it consistent with similar nodes e.g. Lambda. This is specifically needed for transformation of patterns in HSX. ** 1.3.x 1.3.4 --> 1.3.5 =============== * Added an entry point in the parser for statements, and an instance Parseable Stmt to go with it. * Ensured that .Annotated exports all relevant parseXXX(WithYYY) functions. 1.3.3 --> 1.3.4 =============== * Operator fixities are now resolved in patterns. 1.3.2 --> 1.3.3 =============== * Fixes a bug where qualified keywords are rejected even if the extension that enables the keyword in question is not turned on. 1.3.0 --> 1.3.2 =============== (Let's forget 1.3.1 ever existed.) * Fix a bug where declarations of infix operators were not properly merged as FunBinds.
