Projects that depend on the vty package?

Hello,
For further development of the vty package I'm really only paying
attention to the requirements that fall out of the Yi project. Are
there any other projects that depend on the vty package?

In addition, the vty project has it's own wiki: http://trac.haskell.org/vty/
Right now there isn't much information there but it is a great place
to send bug reports or enhancement requests if you have them.

Cheers,
Corey O'Connor

Hi Corey.. I noticed this thread via Haskell Weekly News.

Why yes! I just used it within the hledger project.

I found it easier to get started with the (h/nano)curses libs. From your 
cursor-moving example I started tweaking and soon had a working ui. It 
works well here and I'm hoping it will be pretty robust across platforms.

More top of the head feedback:

I liked the level of abstraction, it seems to handle a lot of routine 
stuff for me. I liked to hear that it avoids flicker that (apparently) 
curses suffers from.

I expected renderBS to convert a multiline string into an Image of 
height > 1.

It might be nice if the <-> and <|> combinators were more forgiving 
about mismatching dimensions, I get unexpected failures from them. After 
a failure like this my program quits but the terminal is not properly 
reset until I run "reset" manually.

I believe vty supports only whole-screen updates, and you could write 
more performant uis by careful use of *curses ? My experiment is quick 
enough for regular use on my macbook, but I can only move the cursor so

I meant: easier THAN the curses libs.

Thanks for the reply! I will try out hledger and verify (As much as I
can) that I don't introduce regressions with any changes I make.

I'm going to add the issues you outline below to VTY's issue tracker
(http://trac.haskell.org/vty/)
If you think of anything else feel free to file an issue there. Though
reports directly sent to me or added to the Yi issue tracker will work
as well.

Agreed.

You can grep the complete .cabal file set on hackage, which I did,
yielding the following versions of the follwoing packages:

    ./yi-vty/0.3/yi-vty.cabal
    ./yi-vty/0.2/yi-vty.cabal
    ./yi-vty/0.2.1/yi-vty.cabal

    ./yi/0.4.1/yi.cabal
    ./yi/0.4.6/yi.cabal
    ./yi/0.3/yi.cabal
    ./yi/0.5.0.1/yi.cabal
    ./yi/0.2/yi.cabal
    ./yi/0.4.3/yi.cabal
    ./yi/0.4.6.2/yi.cabal
    ./yi/0.5.2/yi.cabal
    ./yi/0.4/yi.cabal

    ./LambdaHack/0.1.20080413/LambdaHack.cabal
    ./LambdaHack/0.1.20080412/LambdaHack.cabal

I haven't been using it for anything real, but I was playing around
with it in preparation for yet another project that hasn't taken off
(and it never might).  Anyway, it is a nice _low-level_ library, do
you have any plans on building convenient things on top of it?  Basic
widgets such as dialogues and lists spring to mind...

This is a rather pathetic list widget I came up with at the time:

module Main
    where

import Data.Maybe
import Graphics.Vty
import qualified Data.ByteString.Char8 as B

options = [ "01 Foo", "02 Bar", "03 Baz", "04 Qux", "05 Quux", "06
Quuux", "07 Foo", "08 Bar", "09 Baz", "10 Qux", "11 Quux", "12 Quuux",
"13 Foo", "14 Bar", "15 Baz", "16 Qux", "17 Quux", "18 Quuux", "19
Foo", "20 Bar", "21 Baz", "22 Qux", "23 Quux", "24 Quuux", "25 Foo",
"26 Bar", "27 Baz", "28 Qux", "29 Quux", "30 Quuux", "31 Foo", "32
