Editing IDEs (section)

== Notable features of interest to consider ==

This is a list of features that any Haskell IDE could or should have. The IDEs listed below generally support some subset of these features. Please add more to this list if you think of anything. In future this should be expanded into separate headings with more description of how they would desirably work. For a discussion of IDEs there is the [https://groups.google.com/forum/#!forum/haskell-ide haskell-ide mailing list] and the [https://github.com/haskell/haskell-ide haskell-ide repository]

* Syntax highlighting (e.g. for Haskell, Cabal, Literate Haskell, Core, etc.)
* Macros (e.g. inserting imports/aligning/sorting imports, aligning up text, transposing/switching/moving things around)
* Type information (e.g. type at point, info at point, type of expression)
* IntelliSense/completion (e.g. jump-to-definition, who-calls, calls-who, search by type, completion, etc.)
* Project management (e.g. understanding of Cabal, configuration/building/installing, package sandboxing)
* Interactive REPL (e.g. GHCi/Hugs interaction, expression evaluation and such)
* Knowledge of Haskell in the GHCi/GHC side (e.g. understanding error types, the REPL, REPL objects, object inspection)
* Indentation support (e.g. tab cycle, simple back-forward indentation, whole area indentation, structured editing, etc.)
* Proper syntactic awareness of Haskell (e.g. with a proper parser and proper editor transpositions a la the structured editors of the 80s and Isabel et al)
* Documentation support (e.g. ability to call up documentation of symbol or module, either in the editor, or in the browser)
* Debugger support (e.g. stepping, breakpoints, etc.)
* Refactoring support (e.g. symbol renaming, hlint, etc.)
* Templates (e.g. snippets, Zen Coding type stuff, filling in all the cases of a case, etc.)
