Re: [Haskell-cafe] Haskell syntax/indentation for vim
Here is the crazy idea; instead of having a vim plugin to rule-them-all, why you don't join your efforts and create a plugin which does only indentation for Haskell code? This way, we could have a modular stack and be free to use whatever plugins work for syntax highlighting / unicode syntactic sugar / whatever, but still have a de facto plugin for indenting haskell code in Vim in a smart way :) A.- ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Haskell syntax/indentation for vim
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.

Re: [Haskell-cafe] Haskell syntax/indentation for vim
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.

Re: [Haskell-cafe] Haskell syntax/indentation for vim
They're hard to come by, but some other examples might be... 1) If you type something that is recognizably a guard, it could pop back other guards: foo x y z | guard1 = do ... | guard2 = -- outdent now Not sure how feasible that one is. 2) When you type 'else', outdent to the same indentation as the associated 'then'. There may be others, but those are what I could think of after a few minutes of pondering.

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 - ...
