Hi Samuel!
By "an inspector" do you mean like what this package does?
https://github.com/mmontone/emacs-inspector
I have just tried this
(defun inspector-inspect-region (b e)
(interactive "r")
(inspector-inspect-expression (buffer-substring b e)))
in a grep buffer, and it seems that the current version of inspector
doesn't have support for treating strings with text properties as
trees... and then I tried this on the same grep buffer,
(defun inspector-inspect-region (b e)
(interactive "r")
(inspector-inspect-expression
'(ee-string-intervals
(buffer-substring b e))))
where ee-string-intervals is the function defined here,
(find-eev "eev-blinks.el" "find-eregionpp")
http://angg.twu.net/eev-current/eev-blinks.el.html#find-eregionpp
and it worked very well - it was even able to show that certain
#s(...) objects are structs of the kind "compilation--message", and it
showed its slots.
I have added inspector's author - Mariano Montone - to the list of
recipients of this message, let's see what happens... =)
Cheers,
