+Load the =matchable= module so I can use =match-lambda=.
+
+#+BEGIN_SRC scheme
+  (use matchable)
+#+END_SRC
+
+Set the default font and color to something nicer.
+
+#+BEGIN_SRC scheme
+  (text-widget-font "Fantasque Sans Mono-13:bold")
+  (text-widget-color "#ededed")
+#+END_SRC
+
+This formatter will parse the herbstluftwm tag status line, which
+looks like this:
+
+#+BEGIN_EXAMPLE
+  #1  -2  :3  :4  :5  .6  .7  .8  .9
+#+END_EXAMPLE
+
+And turn it into something more useful. The symbols before the tag
+names (numbers) have the following meaning:
+
+- =#= :: This tag is currently active.
+- =-= :: This tag is visible on another monitor.
+- =:= :: This tag isn't displayed, but has windows on it.
+- =.= :: This tag isn't displayed and is empty.
+- =!= :: This tag has an urgent window on it.
+
+First the tag line has to be split into separate parts. Each tag
+status/name pair is split by a tab character and each status is only
+one character. So I split the whole string on tabs and then make a
+list out of each individual part, for easy access to the status
+character. So we end up with something like:
+
+#+BEGIN_EXAMPLE
+  ((#\# #\1) (#\- #\2) (#\: #\3) ...)
+#+END_EXAMPLE
+
+#+BEGIN_SRC scheme
+  (define (split-tag-list str)
+    (map string->list (string-split str "\t")))
+#+END_SRC
+
+Next we turn each part into something practical for display in
+mowedline.
+
+#+BEGIN_SRC scheme
+  (define tag-display
+    (match-lambda
+     ((#\# . name-list)
+      (list '(color "#ececec" font "FontAwesome-10" "")
+            (string-append " " (list->string name-list) " ")))
+     ((#\- . _) '((color "#bfbfbf" font "FontAwesome-10" "") " "))
+     ((#\. . _) '((color "#969696" font "FontAwesome-10" "") " "))
+     ((#\: . _) '((color "#969696" font "FontAwesome-10" "") " "))
+     ((#\! . _) '((color "#a85454" font "FontAwesome-10" "") " "))))
+
+  (define (tag-list-display tag-list)
+    (map tag-display tag-list))
+#+END_SRC
+
+Finally, bring it all together in a function that can be used as a
+mowedline text formatter.
+
+#+BEGIN_SRC scheme
+  (define (tag-list-formatter text)
+    (tag-list-display (split-tag-list text)))
+#+END_SRC
+
+Create a mowedline window, put it at the bottom.
+
+#+BEGIN_SRC scheme
+  (window #:position 'bottom
+          #:width 1843
+          #:margin-bottom 15
+          #:margin-left 46
+          #:margin-right 15
+          #:background 'transparent
+
+          (widget:text #:name "taglist" #:format tag-list-formatter)
+          (widget:spacer #:flex 1)
+          (widget:clock))
+#+END_SRC
