custom props in `org-agenda-get-scheduled`

custom props in `org-agenda-get-scheduled`

[Samuel Maynard]

Hi all,

First time on the mailing list. Been using org-mode for about half a year.

I'm trying to add a custom display to the agenda view, similar to 
org-habit. I'm want to pull information from a task's `:LOGBOOK:` drawer 
and display some stats next to the item in the agenda view.

I've written the code that parses the stats I'm interested in, but I 
can't seem to figure out how to show them in the agenda. Looking through 
the org-habit code it seems I need to first use `org-add-props` (or 
`add-text-properties`) to add a custom `text-property`, which I can then 
process in an `org-finalize-hook`.

The problem is that there doesn't seem to be any hook available for me 
to add a prop during the agenda creation process. Am I missing 
something? Or do I just need to modify `org-agenda-get-scheduled` directly?

Thanks,
Sam

The closest to what you want is org-agenda-prefix-format, where you can
add user-defined functions to format prefix strings in agenda. The
function will be ran with point at the headline in org file. 

Alternatively, you may add a function cycling over the agenda headlines
to org-agenda-finalize-hook. Then, you can edit the agenda lines as you
wish. Every headline in agenda has 'org-hd-marker text property pointing
to the headline position in the org file.

Hope it helps.

Best,
Ihor
