FP Complete's Hackage mirror - FP Complete
We have been running a mirror of Hackage package repository which we use internally for the FP Complete Haskell Centre’s IDE, building Stackage, and other purposes. This has been an open secret, but now we’re making it official. To use it, replace the remote-repo line in your ~/.cabal/config with the following: remote-repo: hackage.fpcomplete.com:https://hackage.fpcomplete.com/ Then run cabal upda
haskell.org and the Evil Cabal - Michael Snoyman's blog
There's no point being coy or saying anything but what I actually believe, and saying it bluntly. So here it is: The haskell.org committee has consistently engaged in tactics which silence the voices of all non-members, and stacks the committee to prevent dissenting opinions from joining. I've said various parts of this previously. You may have heard me say things like the haskell.org oligarchy, r
mwc-random
mwc-random: Fast, high quality pseudo random number generation This package contains code for generating high quality random numbers that follow either a uniform or normal distribution. The generated numbers are suitable for use in statistical applications. The uniform PRNG uses Marsaglia's MWC256 (also known as MWC8222) multiply-with-carry generator, which has a period of 2^8222 and fares well in
optparse-applicative
optparse-applicative optparse-applicative is a haskell library for parsing options on the command line, and providing a powerful applicative interface for composing them. optparse-applicative takes care of reading and validating the arguments passed to the command line, handling and reporting errors, generating a usage line, a comprehensive help screen, and enabling context-sensitive bash, zsh, an

砂場遊びは地獄のかほり - ぼくのぬまち 出張版
この記事は Haskell Advent Calendar 2013 1日目前半の記事です．後半の記事もよろしく． cabal sandboxは便利だけどdep hellが無くなったわけではない．ほとんどにわかに見えなくなっただけだ．むしろsandboxに甘えて針穴通すようなbuild-dependsを書いてしまうようでは，すぐにまた地獄は-よりおぞましくなって-我々の前にその姿を現すだろう．しかも，そうなったときは最早避けようもない．みんなgems/bundlerやらcpan/cpanmやら先達のアレコレ見てきてイロイロと「こうなってるとマズい」という反省も貯まっているんじゃないのかねぇ？ 特に，Debianなど全体で一貫した依存関係を目指し，かなりの気合いを入れてhackageも取り込んでメンテナンスしてくれてるディストリビューションにおいて dep hellに引き摺り込むようなhac
The Problem with Curation
Recently I received a question from a user asking about "cabal hell" when installing one of my packages. The scenario in question worked fine for us, but for some reason it wasn't working for the user. When users report problems like this they usually do not provide enough information for us to solve it. So then we begin the sometimes arduous back and forth process of gathering the information we
HackageDB: monad-control
monad-control: Lift control operations, like exception catching, through monad transformers This package defines the type class MonadBaseControl, a subset of MonadBase into which generic control operations such as catch can be lifted from IO or any other base monad. Instances are based on monad transformers in MonadTransControl, which includes all standard monad transformers in the transformers li
reflection
reflection: Reifies arbitrary terms into types that can be reflected back into terms This package addresses the configuration problem which is propagating configurations that are available at run-time, allowing multiple configurations to coexist without resorting to mutable global variables or System.IO.Unsafe.unsafePerformIO. That package is an implementation of the ideas presented in the paper "
Hackage dependency monitor
Hackage Dependency Monitor Reverse Dependency List | License List What is this? It can often get tedious to keep your package dependencies up-to-date. This tool is meant to alleviate a lot of the burden. It will automatically determine when an upper bound on a package prevents the usage of a newer version. For example, if foo depends on bar >= 0.1 && < 0.2, and bar 0.2 exists, this tool will flag
cabal sandbox + LTS Haskell - Qiita
(2015-08-27 追記) この記事は無視して stack コマンドを使いましょう Haskellでプログラムを楽しむときに外部のライブラリを利用したくなることがある。cabal install コマンドを使えば ~/.cabal/ 以下に外部ライブラリをインストールして利用することができる。 外部ライブラリは他ライブラリの特定のバージョンに依存していることが多い。依存関係が衝突した場合、ライブラリ群を同時にインストールできないことがある。たとえばライブラリAがライブラリXのバージョン1に、ライブラリBがライブラリXのバージョン2に依存する場合には、AとBを同時に ~/.cabal/ にインストールすることはできない。 ひとつのプロジェクトから A と B に依存することはないが、ひとつのプロジェクトでは A に依存し、もうひとつのプロジェクトで B に依存したいことはあるので困る。こ
