First, I thank Slava Barinov for his proposed patch to appending a
#+tblfm line to an org-collector table. Date: 17 Mar 2019 13:22:58 +0300
Message-ID: <87sgvl4wes.fsf@gmail.com> (raw)
Attached is my, in all modesty named, cm-org-collector.el in which I
have added code to prepend name and attribute headers to the table, for
example:
* orgcollector experiment
:PROPERTIES:
:ID: test
:END:
** Heading One
** Heading two
#+BEGIN: propview :id "test" :cols (ITEM) :noquote t :defaultval ""
:tblfm "@>$>" :tblname "That" :tblattributes "#+attr_latex:
somethingelse" :content ""
#+name: That
#+attr_latex: somethingelse
| ITEM |
|-------------------------|
| orgcollector experiment |
| Heading One |
| Heading two |
|-------------------------|
| |
#+tblfm: @>$>
#+END:
Please note that the :content param must be set to an empty string on
the #+BEGIN: propview line. Without doing so, upon evaluation of the
block, the table is updated; however, the following conditions result:
(error "(user-error Not at a table)")
the #+tblfm line is not replaced but an additional #+tblfm line is
added, and
the #+name and #+attr headers do not reflect any changes to :tblname and
tblattributes if made in the propview line.
I realize that org-collector is an orphan and that it requires
additional documentation. (See Bastien's comments to Slava's message.)
That said, if anyone so desires, please consider these additions, make
all appropriate changes and corrections and patch them to
org-coolector.el. I believe that this additional code makes
org-collector more useful as database tool. Instead of having to add
headers after evaluation, those headers would be inserted at the correct
point when the propview is evaluated. The resulting table can be called
from other code blocks. Also, the #+attr header allows, I believe, for
exporting as desired. (I tried only a latex to pdf and it worked OK.)
I imagine other header params may be included as well.

;; Pass in an alist of columns, each column can be either a single

;;
;; For example the following propview block would collect the value of
;; the 'amount' property from each header in the current buffer
;;
;; #+BEGIN: propview :cols (ITEM amount)
;; | "ITEM" | "amount" |
;; |---------------------+----------|
;; | "December Spending" | 0 |
;; | "Grocery Store" | 56.77 |
;; | "Athletic club" | 75.0 |
;; | "Restaurant" | 30.67 |
;; | "January Spending" | 0 |
;; | "Athletic club" | 75.0 |
;; | "Restaurant" | 50.00 |
;; |---------------------+----------|
;; | | |
;; #+END:
;;
;; This slightly more selective propview block will limit those
;; headers included to those in the subtree with the id 'december'
;; in which the spendtype property is equal to "food"
;;
;; #+BEGIN: propview :id "december" :conds ((string= spendtype "food")) :cols (ITEM amount)
;; | "ITEM" | "amount" |
;; |-----------------+----------|
;; | "Grocery Store" | 56.77 |
;; | "Restaurant" | 30.67 |
;; |-----------------+----------|
;; | | |
;; #+END:
;;
;; Org Collector allows arbitrary processing of the property values
;; through elisp in the cols: property. This allows for both simple
;; computations as in the following example
;;
;; #+BEGIN: propview :id "results" :cols (ITEM f d list (apply '+ list) (+ f d))
;; | "ITEM" | "f" | "d" | "list" | "(apply (quote +) list)" | "(+ f d)" |
;; |--------+-----+-----+-------------------------+--------------------------+-----------|
;; | "run1" | 2 | 33 | (quote (9 2 3 4 5 6 7)) | 36 | 35 |

;; or more complex computations as in the following example taken from
;; an org file where each header in "results" subtree contained a
;; property "sorted_hits" which was passed through the
;; "average-precision" elisp function

Thanks for sharing!
Note that org-collector is currently unmaintained.
We are looking to new maintainers for it (and other packages from
https://git.sr.ht/~bzg/org-contrib).
You appear to be actively using org-collector.
Would you be interested to take over the maintenance?
Best,
Ihor
