Hi!

In short: can we get a cached org-buffer-property-keys please?


My background story:

I love using following function which gives me a neat functionality:
I mark a string, press the keybinding shortcut, and gets asked which
property should be replaced/filled with the marked region text.

Very handy when you've got a new phone number of a contact which
should find its way to the associated property.

(defun my-org-region-to-property (&optional property)
  (interactive)
  ;; if no region is defined, do nothing
  (if (use-region-p)
      ;; if a region string is found, ask for a property and set property to
      ;; the string in the region
      (let ((val (replace-regexp-in-string
                  "\\`[ \t\n]*" ""
                  (replace-regexp-in-string "[ \t\n]*\\'" ""
                                            (substring (buffer-string)
                                                       (- (region-beginning) 1)
                                                       (region-end))))
                 )
            ;; if none was stated by user, read property from user
            (prop (or property
                      (org-read-property-name))))
        ;; set property
        (org-set-property prop val))))

A big drawback is that I have to wait 18 seconds(!) until
org-read-property-name which calls org-buffer-property-keys asks for
the property. This is a real show stopper for this cool function.

Since the properties of a buffer do not change that often, caching
its previous result would make sense to me. This way, I only have to
wait 18 seconds once per file on the first call.

An alternative would be a org-read-property-name which uses only the
properties of the current heading.


Thanks for your support!

Nice function!
Maybe a rewrite of (org-read-property-name) calling
(org-entry-properties) could speed up things.
(org-entry-properties) returns an assoc list of the local header properties.

I agree. The OP should use `org-entry-properties' instead of
`org-buffer-property-keys' in his function, so as to get local header
properties.

OK, great idea.

I tried by myself (Elisp noob) and failed: see code below.

The code evaluates without complaining but when I use the function,
I get asked for a property which gets also correctly written to the
property. However, the completion of the property does not work.

I'm sure, it's only a small error of mine. 

Thanks for your help here!

Hello,

> I'm sure, it's only a small error of mine.

Replace `(mapcar #'list (org-entry-properties nil nil))` by
`(org-entry-properties nil nil)` in your `org-read-entry-property-name`
definition:

```
(defun org-read-entry-property-name ()
  "Read a property name from the current entry (basically a rewrite of
   org-read-property-name which uses org-entry-properties instead to speed
up)"
  (let ((completion-ignore-case t)
        (default-prop (or (and (org-at-property-p)
                               (org-match-string-no-properties 2))
                          org-last-set-property)))
    (org-completing-read
     (concat "Property"
             (if default-prop (concat " [" default-prop "]") "")
             ": ")
     (org-entry-properties nil nil)
     nil nil nil nil default-prop)))
```

Also, for information you could use format function.
It clarifies the prompt computation ^^:

```
(defun org-read-entry-property-name ()
  "Read a property name from the current entry."
  (let ((completion-ignore-case t)
        (default-prop (or (and (org-at-property-p)
                               (org-match-string-no-properties 2))
                          org-last-set-property)))
    (org-completing-read
     (format "Property [%s]: " (if default-prop default-prop ""))
     (org-entry-properties nil nil)
     nil nil nil nil default-prop)))
```
