Dynamic Org-capture Templates

Dynamic Org-capture Templates

[Eric Thomas]

Does anyone know how to approach creating dynamic Org-capture
templates? I'm looking for IDO/Helm type of completion after a
template has been selected. If string does not exist, it is created
and added to future completions, similar to new files in emacs.

Example:

C-c c
"a" (activity)
Activity: math               (<--need completion here)
Topic: multiplication       (<--need completion here)
Date: 2017-09-11           (<--need default to todays date)
Start time: 07:00 AM      (<--need to define AM/PM easily)
Duration: 20                   (<--easier way to capture time?)
Unit: mins

And

C-c c
"a" (activity)
Activity: physical education (<--again, completion starts as "ph.." is typed)
Type: Yoga                         (<--completion)
Class: Level 2 flow              (<--completion)
Date: 2017-09-11                 (<--date picker of some kind)
Start time: 07:00 AM           (<--define AM/PM easily)
Duration: 90                        (<--easy method for capturing time)
Unit: mins


Maybe Org-capture templates are not the correct way to approach this?
Any direction is appreciated.

Thanks

From doc string for `org-capture-templates`:
  %^{prompt}  Prompt the user for a string and replace this sequence with it.
              A default value and a completion table ca be specified like this:
              %^{prompt|default|completion2|completion3|...}.

I think to get completion you would need to dynamically build the value
for `org-capture-templates` which would include the completion
candidates for reach field. I think that's not a great way to do
it. Someone else can suggest a better way, I think.
