dev-haskell / options

A powerful and easy-to-use command-line option parser

Official package sites : https://john-millikin.com/software/haskell-options/ ·

The @options@ package lets library and application developers easily work with command-line options. The following example is a full program that can accept two options, @--message@ and @--quiet@: @ import Control.Applicative import Options data MainOptions = MainOptions &#x20; &#x7b; optMessage :: String &#x20; , optQuiet :: Bool &#x20; &#x7d; instance 'Options' MainOptions where &#x20; defineOptions = pure MainOptions &#x20; \<*\> simpleOption \"message\" \"Hello world!\" &#x20; \"A message to show the user.\" &#x20; \<*\> simpleOption \"quiet\" False &#x20; \"Whether to be quiet.\" main :: IO () main = runCommand $ \\opts args -> do &#x20; if optQuiet opts &#x20; then return () &#x20; else putStrLn (optMessage opts) @ >$ ./hello >Hello world! >$ ./hello --message='ciao mondo' >ciao mondo >$ ./hello --quiet >$ In addition, this library will automatically create documentation options such as @--help@ and @--help-all@: >$ ./hello --help >Help Options: > -h, --help > Show option summary. > --help-all > Show all help options. > >Application Options: > --message :: text > A message to show the user. > default: "Hello world!" > --quiet :: bool > Whether to be quiet. > default: false

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>

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.
