# This file implements a parser for html snippets, meant to be used by a
-# WYSIWYG editor. Hence it does not attempt to parse doctypes, <html>, <head>
-# or <body> tags, nor does it produce the top level "document" node in the dom
-# tree, nor nodes for html, head or body. Comments containing "fixfull"
-# indicate places where additional code is needed for full HTML document
-# parsing.
+# WYSIWYG editor.
+
+# The implementation is a pretty direct implementation of the parsing algorithm
+# described here:
+# http://www.w3.org/TR/html5/syntax.html#preprocessing-the-input-stream
+#
+# Deviations from that spec:
+#
+# Purposeful: search this file for "WHATWG"
+#
+# Not finished yet: search this file for "fixfull", "TODO" and "FIXME"
+
+
+# stacks/lists
+#
+# the spec uses a many different words do indicate which ends of lists/stacks
+# they are talking about (and relative movement within the lists/stacks). This
+# section splains. I'm implementing "lists" (afe and open_els) the same way
+# (both as stacks)
+#
+# stacks grow downward (current element is index=0)
#
-# Instead, the data structure produced by this parser is an array of nodes.
+# example: open_els = [a, b, c, d, e, f, g]
#
+# "grows downwards" means it's visualized like this: (index: el, names)
+#
+# 6: g "start of the list", "topmost", "first"
+# 5: f
+# 4: e "previous" (to d), "above", "before"
+# 3: d (previous/next are relative to this element)
+# 2: c "next", "after", "lower", "below"
+# 1: b
+# 0: a "end of the list", "current node", "bottommost", "last"
+

+# note: to get this to run outside a browser, you'll have to write a native
