[Haskell-cafe] Haskell syntax/indentation for vim
Cafe, I've recently been playing with vim and wasn't quite satisfied with the existing syntax highlighting and indentation, so I thought I'd try my hand at a new Haskell mode: https://github.com/travitch/hasksyn It is minimal in that it doesn't provide support for running external commands over code or anything fancy. 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. Comments, bug reports, and suggestions welcome. pgpORkKFqycGE.pgp Description: PGP signature ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I see now in your README that you have seen vim2hs. I'd love to hear what you disliked about it, especially given my plan to rewrite the whole thing [1]! :) [1] https://github.com/dag/vim2hs/issues/45 On Sun, Mar 3, 2013 at 3:38 PM, dag.odenh...@gmail.com < dag.odenh...@gmail.com> wrote: > Hi > > Have you seen vim2hs? > > https://github.com/dag/vim2hs > > > On Sat, Mar 2, 2013 at 9:11 PM, Tristan Ravitch wrote: > >> Cafe, >> >> I've recently been playing with vim and wasn't quite satisfied with the >> existing syntax highlighting and indentation, so I thought I'd try my >> hand at a new Haskell mode: >> >> https://github.com/travitch/hasksyn >> >> It is minimal in that it doesn't provide support for running external >> commands over code or anything fancy.

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. 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.

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 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.

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
