[Haskell-cafe] ANN: E-book version of the Typeclassopedia
While re-reading Brent Yorgey's Excellent Typeclassopedia I converted it to Pandoc Markdown in order to be able to create an EPUB version. Having a “real” e-book meant that I could comfortably read it on my e-book reader and highlight text and take notes while reading. I also fixed some minor issues while reading it. (These fixes were of course backported to the official Typeclassopedia version on the Haskell Wiki.) The EPUB file can be downloaded from Github: https://github.com/ehamberg/typeclassopedia-md/releases The Markdown source is also available in that repo and you can of course use Pandoc to convert the Markdown file to all the other output formats Pandoc supports. By using a program like Calibre, the EPUB file can be converted to other e-book formats such as the Kindle format. I hope people find this useful. :-) -- Erlend Hamberg ehamb...@gmail.com ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Haskell syntax/indentation for vim
Hi, I wrote a Haskell indenter for Haskell for the Kate editor a few years ago, which – if I remember correctly – worked quite well. It's quite simple and doesn't try to bee *too* clever, but has some logic for when it should dedent. Not sure if it's helpful, but you could have a look (it's well-commented javascript): https://projects.kde.org/projects/kde/kde-baseapps/kate/repository/revisions/master/entry/part/script/data/indentation/haskell.js Erlend On 4 March 2013 09:40, Tristan Ravitch travi...@cs.wisc.edu wrote: I like automatic outdenting too, but I only came up with three cases where I felt like I could do it reliably: * With let/in as you described * After a catchall case: case ... of C1 - ... C2 - ... _ - ... -- dedent back to here * And similarly after a do block ending in a return Even that last one is slightly questionable, I feel, but probably works for almost all cases. Are there any others? On Mon, Mar 04, 2013 at 12:20:12PM -0500, Dan Doel wrote: I hadn't seen this before, but I tried it out, and the parts I'm interested in are nice. The indenting is less flaky than what I was using before (comments had issues). If you're rewriting things, though, it'd be nice to be able to customize indentation a little more. For instance, I like laying out ifs like: if foo then bar else baz But I like to lay out wheres as: foo = ... where bar = ... But both the indents here are based on shiftwidth, so they're tied together. Another 'nice to have' would be some intelligent outdenting. For instance, if you type a let block right now: let foo = zig bar = zag in ... That's what you'll get. It'd be nice if typing the 'in' snapped back to the let. I know it's possible to implement something like this, because the scala indentation mode I use frequently outdents when I type '=' (which annoys the hell out of me, because it's almost never correct), but I don't know if it can be done intelligently enough to be useful (which would be important). Something to keep in mind, though. -- Dan On Sun, Mar 3, 2013 at 9:48 AM, dag.odenh...@gmail.com dag.odenh...@gmail.com wrote: I see now in your README that you have seen vim2hs.

It just does syntax highlighting and reasonably-smart indentation. There is no support for literate Haskell since supporting both with one mode is very tricky. It might be useful to some people.

[Haskell-cafe] IPv6 issues for (code|community).haskell.org?
Hi, When I wanted to get the newest xmonad code from darcs today¹ it was really, really slow. Running “host” revealed that code.haskell.org is an alias for community.haskell.org and that it has an IPv6 address associated with it. Being on an IPv6 network, and having been burnt by similar problems before, I tried adding IPv4 address for code.haskell.org in /etc/hosts in order to force the connection to happen over IPv4. This fixed the issue and “darcs get” now takes a few minutes. I just wanted to alert people in case the problem is at the server end. (And in case this isn’t just a temporary problem.) Connecting to code.haskell.org in a Web browser also takes minutes, while e.g. http://ipv6.google.com/ works perfectly.
