EclipseFP Haskell 2.0.1
Release Notes
We're moving to a 3 integer version identifier, since it's used for Eclipse plugins (see 2.0.0 is the version following 1.111. 2.0.1 fixes a dependency error on AttoJSON (now builds with version 0.5.8)
You need Scion, the Haskell IDE library. See for more information.
You cannot use the version from Hackage ( since commands have been added for eclipsefp. From version 1.111, eclipsefp includes a modified source distribution of scion, that is built and used by eclipsefp if the use built-in server preferences option is checked. Since it is by default, eclipse might be a bit slow to start the first time scion is built. Otherwise, you can build Scion from source (git clone git://, runhaskell Setup.hs configure/build/install)
- use cabal install to install scion so that dependencies are downloaded
- fix in Cabal parsing with multiple if else
- icons in outline view for Cabal flags/if/else
- do not see build messages multiple times when we have multiple cabal components
- marker position when changing a module breaks another one
- rebuild everything without output on startup to have full definition db
- fixes in Cabal handling when modifying multiple-valued fields
- fixes "file not in module graph" when a source file does not belong to the last Cabal component loaded
- creates Main.hs for new executable in the proper folder as specified by preferences
- when a file is not found in module graph, reset module specific session info to avoid data from the previous file
- Quick fix: adding a new pragma or type definition respects literate format
- 0pening a file not contained in a Cabal component (Setup.hs say) uses a single file component that parses it without any special flag nor dependencies
- Opening Main.hs when the source folder is the project root folder does not fail with File not in Module graph error any more.
- uses GHC lexing for syntax highlighting, which fixes issues with for example character literals, etc.
- selecting an instance declaration in outline view selects the full declaration instead of partially selecting the start of it
- fixes when adding/removing a module to/from several components
- when arbitrary type check cannot be done, the message only appears on per file per session, and contains the file name
- better support of Cabal 1.6
- GHC libraries list in Project Explorer only shows libraries referenced by the project.
- Some more quick fixes around pragmas (more messages handled)
- unused "import libraries" property page changed to provide front end to build-depends field of Cabal (add/remove libraries dependencies)
- compiles under Helios
- if no component (library and/or executable) is selected when creating a project, no cabal file is created. Useful to get a project from a source control.
- tab with for Haskell and Cabal editor exposed as preferences
- More options for syntax highlighting (numbers, etc...)
- By default a new module is included in all the components of the project
- Outline now works on modules that parse but do not typecheck
- Arguments for GHCi launch configurations now split in additional arguments, that you can edit, and other arguments, generated from the cabal info
- removed Antlr parsing and Java based AST representation. Let's just use Scion for all source code parsing.
- uses GHC lexing for syntax highlighting. Same thing, let's leverage Scion.
- Communications with scion using pipes and not network.
Thanks to Han Joosten for his feedback and his help.
