+* Notstumpwm                                    :notion:wm:lua:config:
+
+I have just returned from an excursion into the land of [[http://exherbo.org/][exherbo]], which
+is an awesome source-based distro, and I found that while I was gone,
+something changed that made [[http://www.nongnu.org/stumpwm/][stumpwm]] cause a segmentation fault in X11
+a few seconds after starting up.
+
+I have tried everything I can think of to get it running again, but
+alas, to no avail. So I started looking at alternatives again. Feeling
+a little crazy I decided to give [[http://notion.sf.net][notion]] another try. And it fits
+strangely well.
+
+It's configured/extended in lua, which I'm not particularly fond of,
+and it has a (in my opinion) crazy default configuration. *But* it also
+allows Emacs-like key combinations out-of-the-box, which is a very big
+plus in my book. So the quest to bring it closer to my stumpwm setup
+has begun.
+
+*** Window layout
+
+    One of the nicest additions to my stumpwm configuration I made in
+    the last few weeks was a loaded window configuration which put my
+    Emacs frames in a big chunk of my left monitor, my terminals on my
+    left monitor with just enough space for 80 columns and my web
+    browser filling my right screen. I had also set-up some rules to
+    always place them in the correct spots.
+
+    I have not yet tried to automatically place the windows in the
+    right spots, but I do have the proportions right. I just had to
+    delete the right frames and resize the one for terminals and, by
+    default, notion remembers this set-up and automatically restores it
+    when I log in.
+
+    I will look at creating a special layout for this so I don't have
+    to worry about (accidentally) changing things.
+
+*** run-or-raise
+
+    I found this interesting [[http://www.xsteve.at/prg/ion/ion3_functions_xsteve.lua][page]] about ~run-or-raise~-like functionality
+    for Ion3, which notion is a fork of. This is a little outdated,
+    though, since notion has changed (apparently) the workings of some
+    functions and lua 5.2 introduced the goto keyword, so I had to
+    change it to this:
+
+    #+BEGIN_SRC lua
+      function oni_match_class(class)
+         local result = {}
+         ioncore.clientwin_i(
+            function (win)
+               if class == win:get_ident().class then
+                  table.insert(result, win)
+                  return false
+               end
+               return true
+            end
+         )
+         return result
+      end
+
+      function xsteve_run_byclass(prog, class)
+         local win = oni_match_class(class)[1]
+         if win then
+            win:goto_()
+         else
+            ioncore.exec(prog)
+         end
+      end
+    #+END_SRC
+
+    There is no function to get a list of all the client windows, only
+    a function to iterate over them. For the moment I am only
+    interested in finding the first window with class CLASS, so I
+    return =false= when a match is found, this stops the iteration
+    process. I also had to use the =WRegion.goto_= function, instead of
+    =WRegion.goto= because of the mentioned change in lua 5.2, but they
+    are the same.
+
+    I then only have to bind it:
+
+    #+BEGIN_SRC lua
+      defbindings("WScreen", {
+          -- ...
+          submap("Control+Z", {
+              -- ...
+              kpress("E", "xsteve_run_byclass('emacsclient -ca emacs', 'Emacs')"),
+              kpress("W", "xsteve_run_byclass('conkeror', 'Conkeror')"),
+              kpress("C", "xsteve_run_byclass('urxvt', 'URxvt')"),
+          }),
+      })
+    #+END_SRC
+
+*** Quoting C-z
+
+    One of the coolest things about using a prefix in stumpwm that I
+    have been able to find in precious few other solutions is the
+    ability to send the prefix key to the applications you use, so you
+    don't entirely miss its functionality. In stumpwm this is easy,
+    but in notion its a little more work:
+
+    #+BEGIN_SRC lua
+      defbindings("WClientWin", {
+          -- ...
+          submap("Control+Z", {
+              -- ...
+              kpress("Q", "WClientWin.quote_next(_)"),
+          }),
+      })
+    #+END_SRC
+
+    This means that I have to type =C-z q C-z= to send the =C-z= key to,
+    for instance, Emacs. That a few more keys than I was used to in
+    stumpwm, but at least it's possible.
