#14676: GHCI doesn't recover from bad :add -------------------------------------+------------------------------------- Reporter: Juzley | Owner: Juzley Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 8.2.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by Ben Gamari ): In [changeset:"0bff9e677f0569bc8a7207c20cddddfd67e2448f/ghc" 0bff9e67/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="0bff9e677f0569bc8a7207c20cddddfd67e2448f" Don't add targets that can't be found in GHCi When using the :add command in haxlsh/ghci, a module/file that can't be found is still added to the list of targets, resulting in an error message for the bad module/file for every subsequent usage of the command. The add command should verify that the module/file can be found before adding it to the list of targets. Also add a ":show targets" command to show the currently added list of commands, and an ":unadd" command to remove a target. Test Plan: Add a new GHCi testcase that checks that :add doesn't remember either files or modules that could not be found, and that both the new :show and :unadd commands work as expected.
