If you have never used hsenv before, you should. It’s basically the Haskell’s equivalent of Python’s virtualenv. You can find a tweaked version of hsenv here: I’ve relaxed some requirements in order to make it install on newer GHC releases. Finally, if when using you hit this error: Then, you have a problem with your [...]

Not knowing the rules and with only 30 minutes, I needed some help… So, in case someone asks me again, I’ve implemented the same algorithm in Haskell. I know that there are already a lot of other solutions, but, hey, it was fun!
Also tagged sudokuFew days ago, I rewrote sgrep in Haskell. I was curious to know how it compares to grep in term of execution speed. In particular, I was interested to verify that hsgrep scales as O(log n), instead of O(n), with n being the size of the file analyzed. First of all, in order to have [...]
Also tagged benchmark, grepAs an exercise to learn Haskell, I wrote a specialized grep to work on sorted files. It uses binary search to scan a text file and print all the (consecutive) lines that start with a user defined string. My program is a rewrite of sgrep in Haskell: I called it HSGrep. Code is available on [...]
Also tagged grep, sortedI had to tinker quite a bit before finding a decent configuration for vim to edit Haskell files. Here are the packages and config files I use: Haskell mode: interaction with Haddock, compiler integration, and other general settings. Indentation: proper source code indentation. More configs to enforce good style (no tabs, tabstops, etc.): You can [...]
Also tagged gist, vimTo try to make sense of this, I decided to write a “simple” http client in Haskell in as many styles as I could think of: it’s a long time since I found so many new concepts while studying a new programming language…
