#13831: GHCi ignores -fforce-recomp on first :reload when used with custom preprocessor -------------------------------------+------------------------------------- Reporter: SimonHengel | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 8.0.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Description changed by SimonHengel: @@ -21,0 +21,2 @@ + }}} + {{{ @@ -24,0 +26,2 @@ + }}} + {{{ New description: Steps to reproduce: {{{#!bash #!/bin/bash # file preprocess.sh echo "main = putStrLn \"`date -u`\"" > "$3" echo "Reloaded!" }}} {{{#!hs -- file Main.hs {-# OPTIONS_GHC -fforce-recomp -F -pgmF preprocess.sh #-} }}} {{{ $ chmod +x preprocess.sh $ PATH=.:$PATH ghci Main.hs -v0 Reloaded! *Main> main Thu Jun 15 04:15:26 UTC 2017 }}} {{{ *Main> :reload *Main> main Thu Jun 15 04:15:26 UTC 2017 }}} {{{ *Main> :reload Reloaded! *Main> main Thu Jun 15 04:15:35 UTC 2017 }}} As is evident from the output above, the first `:reload` got lost; {{{preprocessor.sh}}} is not executed at all. The second `:reload` works as expected. -- -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13831#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
