proposed additions to org-collector code

[Charles Millar]

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.
