a good question imo! tangentially, by coincidence i was wanting some
similar things to understand better.
showing the output prettily would be great. c-u c-x = is just a bit
limited. some kind of inspector?
what if we could show all text properties in a buffer kind of like visible-mode?
is it possible to diff two buffers completely? i.e. not only the text
as shown [or folded] but the properties too?
that would allow regression testing of changes that affect only text
properties. i don't mean displaying colors or so as a bespoke
non-traditional diff but rather the text property differnces as text.
can a buffer with text properties be saved to a file and reloaded
preserving properties?
what about visibility and folding? could they be preserved like that
also? my regression testing could be improved.
i also still struggle with visibility and folding and the fucntios for
getting visible-only parts of a buffer, or copying and inserting in
buffers, or looping only visible lines etc. i keep getting results i
do not expect. [cannot debug now.] e.g. i am in magit and it is
partly folded and i want to do various programmatic copy or operate
type operations on visible.
i have not even yet found a good protocol for pp and frineds yet to
insert nicely into buffer at point, when called after a pp expression
with c-x c-=. even for a paren-containing sexp, not only a string
with text properties.
so idk it is probably just me and not finding documentation that suits
me well for it, but it seems a ripe area.
