#7962: "ghc -e <invalid expression>" should return non-zero exit status ------------------------------------+------------------------------------ Reporter: timmaxw | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.6.2 Resolution: | Keywords: Operating System: Linux | Architecture: Unknown/Multiple Type of failure: Other | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: ------------------------------------+------------------------------------ Changes (by khyperia): * cc: hvr (added) Comment: Attempting to take this on as my first ticket, ran into a couple problems. Essentially, using -e eventually calls into code common between GHCi and -e. All the code for the following is in `ghc/InteractiveUI.hs` Relevant control enters in runGHCi, in the `case maybe_exprs` block. Both cases of the block (one with -e arguments, the other with normal interpreting) then call `runCommands`, which eventually filters down to `GhciMonad.runStmt`, which eventually handles the source errors. I am unsure of where to insert the logic to return a nonzero exit code, as putting it in `GhciMonad`/related would also affect normal GHCi. Any tips? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7962#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
