Bug#803685: haskell-devscripts: Please print status messages when generating haddock documentation

[Chris Lamb]

Package: haskell-devscripts
Version: 0.9.11
Severity: wishlist
Tags: patch

Hi,

If we append --verbose=2 to the call to haddock, we get a nice per-line
status of the file currently being processed instead of a single line:

  [..]

  Running hscolour for yi-language-0.1.1.0...
  creating dist-ghc/doc/html/yi-language
  Preprocessing library yi-language-0.1.1.0...
  creating dist-ghc/doc/html/yi-language/src
  /usr/bin/HsColour -print-css -o[..]/hscolour.css
  /usr/bin/HsColour -css -anchor -o[..]/Yi-Buffer-Basic.html
  src/Yi/Buffer/Basic.hs
  /usr/bin/HsColour -css -anchor -o[..]/Yi-Lexer-Abella.html
  dist-ghc/build/Yi/Lexer/Abella.hs
  /usr/bin/HsColour -css -anchor -o[..]/Yi-Lexer-Alex.html
  src/Yi/Lexer/Alex.hs

  [..]

This is nice for larger packages where generating the documentation can
take some time. It no more spam than the per-file ghc status messages
that we currently omit.

Patch attached.


Regards,
