#2049: GHCi doesn't fully load previously broken modules
------------------------+---------------------------------------------------
Reporter: ajd | Owner:
Type: bug | Status: new
Priority: normal | Component: GHCi
Version: 6.8.2 | Severity: normal
Keywords: | Testcase:
Architecture: Unknown | Os: Unknown
------------------------+---------------------------------------------------
Scenario:
I have a project with three modules: Mod1, Mod2 and Mod3. Mod3 calls an
undefined function and so shouldn't load. I call GHCi as
ghci Mod3.hs
The output looks like this:
GHCi, version 6.8.2: http://www.haskell.org/ghc/ :? for help
Loading package base ... linking ... done.
[1 of 3] Compiling Mod1 ( Mod1.hs, interpreted )
[2 of 3] Compiling Mod2 ( Mod2.hs, interpreted )
[3 of 3] Compiling Mod3 ( Mod3.hs, interpreted )
Mod3.hs:6:6: Not in scope: `foo'
Mod3.hs:6:12: Not in scope: `barf'
Failed, modules loaded: Mod2, Mod1.
The problem comes when I edit the file using GHCi's :e command and then
reload with :r. The output looks like this (which is strange in itself,
because the modules are listed in the wrong order):
*Mod2> :r
[3 of 3] Compiling Mod3 ( Mod3.hs, interpreted )
Ok, modules loaded: Mod2, Mod3, Mod1.
The problem is this: when I call a function from Mod3 from the GHCi
toplevel, I get a "not in scope" error. I can call the function as
"Mod3.<function name>" but "Mod3" does not show up in GHCi's tab
completion. I don't believe that this is the correct behavior.
