2015-11-21 v0.5 * Add new options to enable "rigid" layout rules. This makes the annotations more rigid in the sense that if you move AST fragments around it is more likely that their internal components will remain in the same position relative to each other. * Fix a bug where files failed to parse if the file started with comments. * Fix a bug where "[e||" was turned into "[||" 2015-11-15 v0.4.2 * Fix round tripping of arrow notation using ">-" and ">>-". 2015-09-28 v0.4.1 * Revert removing cast from markLocated until further inspection in HaRe. 2015-09-28 v0.4.0.0 * Rework HasDecls so that there are only instances for which it is idempotent. Provide functions for managing an LHsBind which is not idempotent, and performing general transformations on an AST including FunBinds. * Manage LHsDecl instances so that the Annotation always attaches to the wrapped item, so that they can be seamlessly used in a top level (wrapped) or local (unwrapped) context. * Tweak transformations based on HaRe integration. * This release supports the HaRe 8.0 release, which finally works with GHC 7.10.2 * Rename `exactPrintWithAnns` to `exactPrint`. This will possibly break earlier client libraries, but is a simple rename. * Bring in semanticPrintM which allows wrapper functions to be provided for the generated output, for use when emitting e.g. HTML marked up source. 2015-08-13 v0.3.1.1 * Add missing test files to sdist, closes #23 2015-08-02 v0.3.1 * Mark LHS at the beginning of HsCase and HsIf expressions * Mark trailing semi colons on ANN pragmas * Correctly mark trailing semi colons distinctly from internal semicolons * setPrecedingLinesDecl applies the setting to both the Decl and the item wrapped in the Decl. 2015-07-20 v0.3 Substantial rework to manage changes introduced in GHC 7.10.2 rc2 and beyond. Simplification of the core Annotation data type coupled with simplification of the various phases, by @mpickering. Introduction of initial Transform functions, driven by the needs of HaRe [1] and apply-refact [2] for applying hlint hints. Both of these are currently works in progress, and this module is likely to change substantially in future releases. Support for processing files making use of CPP. Links [1] https://github.com/alanz/HaRe/tree/wip [2] https://github.com/mpickering/apply-refact 2015-03-24 v0.2 This release contains a major rewrite of all internal modules. The external interface has also changed significantly. A description is omitted. # Top-level changes The most notable change is that the common structor of the modules known as `ExactPrint` and `Annotate` has been factored out into a common module (`Annotate`). The aforementioned modules are now known as `Delta` and `Print` and contain functions to interpret this common structure. The top level module `ExactPrint` now just reexports a consistent interface from the base modules. Introduced a new module `Lookup` which contains a mapping from AnnKeywordId to their String representation. # Internal Changes `Annotate` contains all the information about which annotations appear on each AST element. This is achieved by building up a syntax tree (using a free monad) which can then be interpreted by programs requiring access to this information. # Layout compensation The method which compensates for layout rules has been clarified. 1. When the Layout Flag is activated in `Annotate`, we mark the current column as the start of the layout block. 2. This is important when we move to a new line. We take the offset at that current point to be the baseline and calculate the correct next position based on this. 3. This method is very general as one can think of a entire source file as obeying layout rules where the offset is equal to zero. 2015-03-11 v0.1.1.0 Handles indentation when the AST is edited Major rework of internal monads by @mpickering 2015-01-28 v0.1.0.1 Update cabal to prevent building with GHC 7.70,thanks @peti 2015-01-24 v0.1.0.0 Initial release, for GHC 7.10 RC 2
