#11695: On GHCi prompt the arrow (movement) keys create strange character sequences ---------------------------------+-------------------------------------- Reporter: heisenbug | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 8.1 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+-------------------------------------- Comment (by heisenbug): Replying to [comment:6 judahj]:
Thanks for the details. To clarify, what machine are you slogin'd *from* into hostB, is it your laptop or hostA? If your laptop, what Windows program are you using to do the connection?
It is not the laptop. The keystroke/mousing/visualization chain is: {{{ laptop <--vnc--> hostA <--ssh--> hostB }}}
(More details: I'm trying to reason about the chain of events from you
pressing your key to it getting received by gghci as the character sequence "\ESC[A" (or similar). The problem is that ghci (really, haskeline) expects to read those characters in a single block, but in your setup they're arriving separately for some reason.) So `ghci` actually utilizes `haskeline`? I heard something to the contrary before. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11695#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
