Re: [Haskell-cafe] Layout styles and EclipseFP evolution.

Note to community. Design the syntax of a language to support auto indenting. Don't make me repeatedly hit the tab key. John On Thu, Dec 16, 2010 at 8:48 PM, Scott Michel wrote:

I've been helping JP with EclipseFP, with the objective of evolving EclipseFP into a relatively high productivity IDE for Haskell.  EclipseFP has the potential to mature into a reasonable platform for making routine coding easy, e.g., a HAppStack plugin that makes writing web apps in Haskell just as easy as it is for the Java community to write web services.

I've just added Haskell code templates (*) to EclipseFP and, in the process, encountered the distinct lack of layout autoindentation. I'm sure it used to exist, but it doesn't exist today. I've looked at the Emacs haskell-mode.el indentation style, which I'm inclined to port over.

Are there other layout autoindentation styles that other people prefer and believe should be supported?

(*) The current development version supports templates like "let" and you get a let expression inserted. Eventually, if you were to type "case" and you tab out of the expression between "case" and "of", you would get the data type's alternatives inserted.

(**) Don S told me that a similar "case" autocompletion exists in another IDE. Yes, EclipseFP is just catching up.

(***) Wishlist: An incremental parser that can accept document changes/deltas and can look backward from the current point to give better context for completions, e.g., the previous token before the editor's point is "import".
