applyStyleOnImport.lua

--[[ This script should be able to auto-apply any style on import.

    I've built this script to disable "base curve" on imported images.
    This is not necessary for the current development branch any more,
    since it allows to disable the automatic application of "base
    curve" in "Settings → core options → quality".  (Version
    2.7.0+1375~g6f0010465)

    To use, import the style `minimal.dtstyle` (switches off the
    basecurve).  Then "require" this script from `luarc` by something
    like

        require('dtscripts/applyStyleOnImport').use('minimal')

    but read `README` to get the path right.  Then restart darktable.

    Missing: Clear history stack first.  Compress history stack
    afterwards.  Remove unused modules.  ]]

    local style = nil
