Hi mailing list,
is something like this of interest to add to org-mode?
Attached is a prototype to a read-only view mode. It tries to hide as much of
markup as possible to make it more "readable". It uses built-in view-mode to
make the buffer read only and enable some common commands. I plan to add more
"dired like" movement though.
I don't claim it is very well written or efficient; I appreciate input on that
regard. To note is that I use minor-modes as "toggles", to make the
functionality avialable as "solo pieces" as well as a code generation tool.
I am just checking interest here. More info and a screencast are avialable at:
https://github.com/amno1/org-view-mode

Yes! Yes! Yes!
I can see all sorts of stuff going from here. Three examples follow.
1. I have a daily journal in Org-mode, and I wrote a simple function
showing me "what happened on this day in all previous years of
journaling". Making that read-only, with view-mode-like bindings is an
obvious thing to do. (In fact, I plan to blog about that function
soon.)
2. I imagine this could be used to create menus, a bit like Magit, with
toggleable sections etc.
3. I once coded myself a kind of "dashboard", showing various things in
(almost) real time - think current time, weather, departures of busses
from a nearby bus stop, Emacs uptime, number of open buffers, a todo
list for today etc. (Sadly, I didn't finish it, though.) A mode
derived from your mode could be great for that.
Thanks a lot for working on this,

Hi Arthur,

I'm interested in Linux-native smartphones (e.g. the Pine Phone) and
in using Org there as fully as possible. I probably wouldn't _alter_
my Org content on the phone as extensively as I do on a laptop, but
I'd certainly like to _see_ all my Org content and have something like
an agenda. Then the question arises of how best to display that
content and support occasional editing of it. Apps like Orgzly have
been developed to meet this need, but (a) Orgzly is Android-specific,
and (b) I would really love if a good answer could be: simply run
Emacs on the phone and view your Org content that way. A read-only
Org view mode feels like it could be a very useful ingredient for
that!
Best wishes,
Neil

Why not just do an ASCII export to a temporary read only buffer for
viewing?
I always thought the point of Org was to have minimal markup so that
the native file was plainly legible.

I'm not being negative about the concept. I'm asking if the poster had
considered using the built-in tools before creating another new
library.
I did a short look at the site and the assertion "view org with less
markup", and that was my first impression.
I had two thoughts. The first was if the markup is a problem and you
want a read only view, why not use the built in ascii export to a
buffer and view that buffer? I just hit C-c C-e t A and M-x
read-only-mode and was able to navigate my ascii org file as a read
only buffer.
Second thought was that Org's syntax was supposed to minimize the
markup so it didn't negatively impact reading. Maybe the poster is
identifying a pain point we should be aware of as a community, ie:
that too much markup makes it hard to read.
My impression is only property drawers and source blocks are
potentially visually loud compared to the other markup. Timestamps are
pretty minimal and links already only show a descriptive text instead
of the full [[]] syntax.
