#11695: On GHCi prompt the arrow (movement) keys create strange character sequences ---------------------------------+-------------------------------------- Reporter: heisenbug | Owner: Type: bug | Status: infoneeded 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): Going via PC <-> VNC <-> hostA I sometimes see {{{ "\ESC[B" "\ESC[" "B" "\ESC[B" "\ESC" "[B" "\ESC[B" }}} The escape sequences seem to break up at strange places. Now the weird part. When going PC <-> hostA <-> hostB and opening an `xterm` there, and feeding `./Read` from there with keystrokes, I sometimes see duplicated escape sequences, but never the broken-up ones. Maybe this is just luck, but I really tried (even with considerable load on hostB). So maybe the X-Windows system is not the culprit at all. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11695#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
