#15887: Ideas for a better GHCi editing experience -------------------------------------+------------------------------------- Reporter: Anchpop | Owner: (none) Type: feature request | Status: new Priority: high | Milestone: Research | needed Component: Compiler | Version: 8.6.2 Resolution: | Keywords: QoL Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by j.waldmann): Can you show an interactive interpreter for some other language that does what you want? Navigating a multi-line text - that's the task of an editor. Syntax highlighting and indentation - that's the task of an IDE. It sounds as if you're suggesting to build a terminal based IDE, and include it with ghci. I think it's more manageable to do this the other way around (some editor connects to ghci) - and there are projects that do this, e.g., https://github.com/alanz/haskell-lsp When I use ghci, and I notice that lines get too long, I first try to break them up by using (one-line) definitions (let foo = expression) in ghci, and if I'm collecting too many of these, I write them into a file. That way, I can edit them better, and I can keep them. Your proposal would improve on "edit them better", but not on extra functionality (write to file). Oh, and I never really need syntax highlighting, There are not that many keywords, and I rarely use them. First-order languages rely on keywords (e.g., while) for control flow. But this is Haskell, and I more often use map, fold, traverse, etc. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15887#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
