#2606: Backspace, delete, etc. don't work in ghci in HEAD
-------------------------------+--------------------------------------------
Reporter: tim | Owner:
Type: bug | Status: closed
Priority: normal | Milestone:
Component: GHCi | Version: 6.10.1
Severity: major | Resolution: invalid
Keywords: | Difficulty: Unknown
Testcase: | Os: Linux
Architecture: x86_64 (amd64) |
-------------------------------+--------------------------------------------
Changes (by japple):
* version: 6.9 => 6.10.1
* architecture: x86 => x86_64 (amd64)
Comment:
ctrl-<left arrow> does not work. #2741 lists a hacky solution for delete.
Is there a solution for the rest of they key bindings? ghci-haskeline
makes no visible difference in the behavior.
