stack haddock should always return location of index.html #781
Description
Hello,
I propose that stack haddock always finishes by printing the location of the index.html file.
It can be inconvenient tracking down the documentation produced by stack haddock while developing a package.
When the command produces documentation, the last line of the output is
Generating Haddock index in
/home/<user>/<projectDirectory>/.stack-work/install/<arch>/<resolver>/<compilerVersion>/doc/index.html
The last line would be useful when there is no new documentation generated.
Steps to reproduce:
- Run
stack haddock - Run
stack haddock
Expected:
The second run produces something like
The Haddock index is already up to date in
/home/<user>/<projectDirectory>/.stack-work/install/<arch>/<resolver>/<compilerVersion>/doc/index.html
Actual:
The command prints nothing.
Here is the stack --version output
$ stack --version
Version 0.1.2.0
Here is the command I ran with --verbose
$ stack haddock --verbose
Version 0.1.2.0
