No, it doesn't?

writeContent: aString

	aString do: [:char |
		(#(10 13) includes: char asciiValue)
			ifTrue: [self cr]
			ifFalse: [char = Character tab
				ifTrue: [self nextPutAll: '    ']
				ifFalse: [(String htmlEntities keyAtValue: char ifAbsent: [])
					ifNil: [self nextPut: char]
					ifNotNil: [:escapeSequence |
						self
							nextPut: $&;
							nextPutAll: escapeSequence;
							nextPut: $;]]]].

Tabs are expanded to four non-breaking spaces.
How's that losing the indent.

No, see above.

So we're in a situation where if one wants to indent we can only do so by applying a <code></code> tag pair (and applying an invisible emphasis to a text).  I think this is poor.  My simple approach doesn't lose indenting, does mean that one can't use an initial paragraph indent, but does allow one, easily, and visibly, to generate correctly indented HTML.

So, lets look: Object>>orderedCollection

Old code/new code, yellow-click, copy as html:
=======================================
<b>asOrderedCollection</b><font color="#000000"><br>
    </font><font color="#007F7F">"Answer an OrderedCollection with the receiver as its only element."</font><font color="#000000"><br>
<br>
    </font><font color="#7F0000">^</font><font color="#000000"> </font><font color="#000000">OrderedCollection</font><font color="#000000"> </font><font color="#00007F">with:</font><font color="#000000"> </font><font color="#7F0000">self</font>
=======================================
Observations:
- colors preserved
- indents preserved!
- Reflows when window too small.
- line breaks correctly honored
- w/o styling, all serif.


New code, select all, cmd-6/doit, yellow-click, copy as html:
=======================================
<code>
<pre><b>asOrderedCollection</b><font color="#000000">
    </font><font color="#007F7F">"Answer an OrderedCollection with the receiver as its only element."</font><font color="#000000">

    </font><font color="#7F0000">^</font><font color="#000000"> OrderedCollection </font><font color="#00007F">with:</font><font color="#000000"> </font><font color="#7F0000">self</font></pre></code>
=======================================
Observations:
- colors preserved
- indents preserved!
- keeps lines, no reflow when window too small.
- line breaks correctly honored
- w/o styling, all monospaced.


inbox version, yellow-click, copy as html:
=======================================
<b>asOrderedCollection</b><font color="#000000"><br>
</font><pre><font color="#000000">    </font><font color="#007F7F">"Answer an OrderedCollection with the receiver as its only element."</font><font color="#000000">
</font></pre><font color="#000000"><br>
</font><pre><font color="#000000">    </font><font color="#7F0000">^</font><font color="#000000"> </font><font color="#000000">OrderedCollection</font><font color="#000000"> </font><font color="#00007F">with:</font><font color="#000000"> </font><font color="#7F0000">self</font></pre>
=======================================
Observations:
- colors preserved
- indents preserved and explicitly colored?
- keeps lines, no reflow when window too small.
- line breaks incorrect, there's an additional space between comment and return?
- first line styled different from rest of method?


So what it does: wrap every _line_ with indent into a <pre>. I find that confusing.
Also, mark-with-doit version is opt-in, inbox-verison is not.

See also attached html and attached screenshot.
I have included a comparison for the indented paragraph example, also.

Best regards
