I have attached screenshots on what I could achieve with the cookie.
I have also provided recipes for how the cookie could be used.
----------------
The information I am looking for is vc state, and it is buried too
deep inside.
Let me elaborate ... if I eval the form you have quoted above, I would
get
(setq x '(modification-hooks
(diff-hl-overlay-modified)
diff-hl-dired-cookie change before-string
#(" " 0 1
(display
((left-fringe exclamation-mark diff-hl-dired-change))))
diff-hl t))
Note that the `diff-hl-dired-cookie` is added by me, and
`diff-hl-dired` adds the follwing properties
- `diff-hl-dired-cookie` :: This is added by me, and contains the vc
state.
- `diff-hl` :: This is added by `diff-hl-dired`, and `t` isn't much
useful for the task I have hand.
- `before-string` :: This is added by `diff-hl-dired`, and the vc
state is avaiable as a face property.
If I have to get to that property, this is the kind of manoeuvre I
need to do
(->> x
(memq 'before-string)
cadr
(get-text-property 0 'display)
car
(-filter 'facep)
car)
If you add a cookie, I can do whatever with it.
Mind you ... I am not saying the relevant information is /not/ there;
I am only saying that it is buried too deep, and not readily accessible.
