org-sync doesn't work with recent org-element.el

org-sync doesn't work with recent org-element.el

[Jonas Hörsch]

hej list,

i've just now been playing around with org-sync [1] and want to start
using it for at least a github and eventually a redmine project.

the first thing which is making me stumble is that while org-sync works
fine with org-element from [2] a current (as in from head of master) one
fails to work at all.

as far as i could track the problem, i understand that the handling of
property drawers changed significantly: while in the former version a
property drawer was just represented by a simple plist, the latter now
introduced a new org-element-type node-property, so it also provides
access to information about f.ex. spacing of individual items in the
property drawer.

and org-sync hasn't been adapted to this yet.

am i correct? did someone start the work on updating org-sync yet?

thanks,
jonas

Hi Jonas,

I'm copying Aurélien, the author of org-sync.

Aurélien, are you willing to maintain org-sync or shall we call for
a new maintainer?

Thanks for your answer!

Best,

I saw the thread but thank you anyway.

I have not given up on org-sync but I have too many things going on
right now. I know it's not the first time I say this but I will get
back to it eventually.

hi all, hi aurélien,

then, i suppose the answer to my main question, whether someone has started
updating org-sync, is a no and i'll thus try.

i'm not too proficient in elisp yet, so any hints of a clean transition
are appreciated. i plan to alter any parts, which read/write cons lists
(i mean those ( key . value ) pairs which used to go under the
:properties key) to node-property elements directly.

if you think a bit of that chore could be abstracted away in a function,
let me know.

cheers,
jonas

retrieve value of a property from a property-drawer (was: org-sync doesn't work with recent org-element.el)

Hej, org-element-wizards,

i found that the following use of org-element-map retrieves reliably
the value of a key from a property drawer.

is such a use, especially the temporary overriding of the headline's
type to org-data, to be considered allowed usage or rather a hack and
thus to be avoided?

                   'node-property
                   (lambda (x) (and (string= (org-element-property :key x) key)
                               (org-element-property :value x)))
                   nil t 'headline))

hej aurélien, list,

as hoped for i got it to work with the current org-element.el with only
few changes to org-sync. i pushed my changes to my github at [1]. please
feel free to comment and/or merge.

the commit

bdcbae os-github: use authentication data also for
os-github-fetch-json-page 

is optional and i wouldn't mind moving that to a separate feature branch
if you prefer.

cheers,
jonas
