Cool, I had seen your previous message before you edited it, so I thought I could make the output a bit more compact and robust, and secretly also a little more similar to Sjasm’s output although that certainly isn’t a design goal 
.
JFYI (I = inspiration? ):
sjasmplus current listing supports fixed-column way to make parsing in some ways simpler (and more difficult in other), so:
* the lines beyond max line number (99999) goes further in the ASCII (100k = ":0000")
* after the line number there're include-depth indicators (if they fit into the 6-char column reserved for line+depth)
* the addresses are truncated to four digits only (0000-FFFF) (I'm not really happy about it, but delaying the change to lst format to some larger version change)
* the machine code bytes are limited to four per line, longer blocks are split over multiple listing lines or using elipsis "..." in certain situations, not listing all of the bytes.
* the single char ahead of assembly source can mark also line emitted by macro ">" or skipped due to conditional assembling "~"
Overall there are many subtle details and corner cases, but checking the tests files it seems the listing stuff is not nicely grouped together, but scattered through the hundreds of tests, so I can't easily point you to some full-like examples of what listing files do, maybe one non-trivial is https://github.com/z00m128/sjasmplus/blob/master/tests/misc/...
If you have particular dilemma and are curious how sjasmplus does it, let me know (maybe github ticket on sjasmplus so I find it quickly, I'm reading the MSX forum only once in couple of days). It may be not a good fit for your Glass, but it may give you inspiration how to not do it. :D Cheers.
I'm with OpenMSX 0.15.0 on Windows 10.
I created a new Dezog release. This release now also supports OpenMSX on Windows.
On Windows not only the socket mechanism is different but somehow it was decided it was a good idea to add enterprise level security as well. 
This complicated the interface with OpenMSX somewhat. 
Nevertheless, this is fixed now. Have fun debugging on Windows!
Install it by running:
code --install-extension dezog-1.3.5.vsix
You''ll find it here.
