example code to reproduce bug ndmitchell/ghcid#57 (comment)
project consist of
-
package 'a' in a/
- library Exposing module A
- executable
-
package 'b' in b/
- depends on 'a'
- library Exposing module B (B import stuff from module A in pakcage a)
- executable
-
package 'ghcid-test' in .
- depends on 'a' and 'b'
- library Exposing module Test
no .ghci file is present
All example above are run from the ghcid-test folder
- simple ghcid invocation : No reloading
$ ghcid
Loading stack ghci --test --ghci-options=-fno-code ...
The following GHC options are incompatible with GHCi and have not been passed to it: -threaded
* * * * * * * *
The main module to load is ambiguous. Candidates are:
1. Package `a' component exe:a-exe with main-is file: /Users/rvion/dev/ghcid-test/a/app/Main.hs
2. Package `b' component exe:b-exe with main-is file: /Users/rvion/dev/ghcid-test/b/app/Main.hs
You can specify which one to pick by:
* Specifying targets to stack ghci e.g. stack ghci a:exe:a-exe
* Specifying what the main is e.g. stack ghci --main-is a:exe:a-exe
Specify main module to use (press enter to load none): Not loading any main modules, as no valid module selected
* Choosing from the candidate above [1..2]
* * * * * * * *
Configuring GHCi with the following packages: ghcid-test, a, b
GHCi, version 7.10.3: http://www.haskell.org/ghc/ :? for help
[1 of 3] Compiling A ( /Users/rvion/dev/ghcid-test/a/src/A.hs, nothing )
[2 of 3] Compiling B ( /Users/rvion/dev/ghcid-test/b/src/B.hs, nothing )
[3 of 3] Compiling Test ( Test.hs, nothing )
Ok, modules loaded: Test, B, A.when I change any file, nothing reload.
here is the output of my stack ghci invocation:
$ stack ghci
