Summary
Common debugging/error/exception functions that give file location information > $(err "OH NO!") > > main:Main main.hs:16:1 OH NO! Notice how it displays package:module file:line:character It exposes the functions err (error), undef (undefined), and trc (Debug.Trace.trace). All of these behave the same as their normal counterpart but also spit out a location. Here is my favorite helper, debug, which is like trace but just show the value. > debug [1,2,3] > > DEBUG: [1,2,3] > [1,2,3] And The Template Haskell version. > $(dbg) [1,2,3] > > DEBUG main:Main main.hs:1:3 [1,2,3] > [1,2,3] Also there is a version of thrwIO that gives location information > ($(thrwIO) $ AException) `catch` \e -> putStrLn ("Caught " ++ show (e :: AException)) > > Caught AException "main:Main test/main.hs:25:6" See module for a listing of all the functions with short descriptions, and the homepage for some more examples https://github.com/gregwebs/ErrorLocation.hs

General
- doc
- Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
- hscolour
- Include coloured haskell sources to generated documentation (dev-haskell/hscolour)
- profile
- Add support for software performance analysis (will likely vary from ebuild to ebuild)
- test
- Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)

*/*: Inline mirror://hackage and update URIs
This change inlines mirror://hackage in all ebuilds, and updates URIs to the modern form (old URIs redirect to that). The change has been made using the following command: find -name '*.ebuild' -exec sed -r -i \ -e 's@mirror://hackage/@https://hackage.haskell.org/@g' \ -e 's@https://hackage.haskell.org/packages/archive/([^/]*)/([^/]*)/@https://hackage.haskell.org/package/\1-\2/@g' \ -e '/hackage\.haskell\.org/s@\$\{PN}-\$\{PV}@${P}@g' \ -e '/hackage\.haskell\.org/s@\$\{MY_PN}-\$\{PV}@${MY_P}@g' \ -e '/hackage\.haskell\.org/s@\$\{PN}-\$\{MY_PV}@${MY_P}@g' \ {} + Signed-off-by: Michał Górny <mgorny@gentoo.org> - Robin H.

proj/gentoo: Initial commit
This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H.
