xmonad@haskell.org<br>Objet : Re: [xmonad] scratchpads broken after \
upgrade.<br><blockquote>Hi Eric,<br><br>the problem is the following \
line:<br><br>&gt; myScratchpadManageHook =<br>&gt;&nbsp;&nbsp;&nbsp;&nbsp; \
manageScratchPad &lt;+&gt;<br>&gt;&nbsp;&nbsp;&nbsp;&nbsp; namedScratchpadManageHook \
scratchpads<br><br>As Brandon said, the X.U.Scratchpad module is deprecated at this \
point<br>(and should have been for 0.17.1 but we didn't notice this in \
time...).<br>If you remove your usage of it, everything should work fine.<br><br>If \
you're interested in the boring explanation: what happens in the<br>background is \
that X.U.Scratchpad just latches onto X.U.NamedScratchpad<br>(NSP) functionality, so \
`scratchpadManageHook' is really just a call to<br>`namedScratchpadManageHook' with a \
custom query (which is one of the<br>reasons we deprecated it).<br><br>Now, in order \
to make NSP more extensible, we shuffled some internals<br>around and made the \
scratchpad functions ignore the scratchpad argument<br>they are given, instead \
referring to some that *that is filled by the<br>NSP manageHook*.&nbsp; This is a bit \
of a hack, but was necessary to<br>facilitate backwards compatibility—it is one of \
the most used modules.<br>However, since the manageHook runs quite often, we don't \
want to fill up<br>the state every time, so there's a small check whether *something* \
is<br>there already.&nbsp; Now, the `(&lt;+&gt;)' operator (which is really \
`(&lt;&gt;)')<br>associates to the left, so when running the code `manageScratchPad' \
will<br>be executed first, fill up the state with a single unnamed scratchpad,<br>and \
call it a day.<br><br>Best,<br>&nbsp; Tony<br><br>-- <br>Tony Zorman | \
