[Haskell-cafe] IDE?

Thank for the reply. 

I'll try the emacs approach (or better Xemacs because Emacs on Windows has
really ugly font smoothing), but I must say that - being an old school
object-oriented programmer who got spoiled by fully integrated IDEs like
Borland's TurboPascal, Microsoft Visual Studio, and Eclipse - switching to
emacs or VIM is not an easy task :) Even on the commodore 64 I used a mini
IDE for writing 6502 assembler ;)

About Apple's Shake: this is a flow-graph based image composition package.
It's like a tiny bit of functional programming (limited to images as
values), represented as a graphical acyclic graph of functional nodes. Each
of these nodes computes a result, and this result can be visualized by
clicking on a button on each node, so you can "debug" the output of any
node. An Haskell IDE could do the same for functions (it's like dynamically
adding an "unsafePerformIO print" to the selected function). And then like
Visual Studio one should be able to write "debugger visualizers"

Yes this is kind of sad.  FWIW, here's how I currently approximate  
these features using Emacs + Haskell mode:

there is HaRe, haven't tried it.

changing a function's type and then recompiling gives you a pretty  
useful todo-list though.  :)

if you run hasktags you can use M-.

not sure, maybe one could cook something up using grep or even hasktags

M-x grep RET downarrow RET

either you use shim or the built-in M-/, which completes everything  
(not semantically sensitive, though)

i don't know shake, can you explain a bit more?

ghc HEAD has the ghci debugger, haven't tried it

i agree
