Hi Org fellows,
I would like to make use of "org-table-get-remote-range()" to write a
spreadsheet formula since I learned I could get more flexibility than
with the standard "remote()" way. Actually, I need to use some variables
to reach a set of cells.
However, I can't get to where I want to.
I will show you a simple example, in the hope you can guide me there.
For sake of simplicity, I will keep static references in the formula.
I have Org mode version 9.1.13 running in GNU Emacs 25.1.1.
Let's have 2 tables, named "MainData" and "ExternalData"
#+NAME: MainData
| Month | x | y |
|--------+-----------+----|
| Set 1 | 1 | 10 |
| Set 2 | | |
| Set 3 | | |
|--------+-----------+----|
| Sum | 2 20 3 30 | |
#+TBLFM: @>$2='(mapconcat 'identity (org-table-get-remote-range
"ExternalData" (concat "@" "I+" "2" "$" "1" ".." "@" "II-" "1" "$" "2"))
" ")::@2$2='(org-table-get-remote-range "ExternalData" (concat "@" "I+"
"1" "$" "1"))::@2$3='(org-table-get-remote-range "ExternalData" (concat
"@" "I+" "1" "$" "2"))
#+NAME: ExternalData
| x | y |
|---+----|
| 1 | 10 |
| 2 | 20 |
| 3 | 30 |
|---+----|
What I could achieve, is to refer to one cell at a time, like in :
@2$2='(org-table-get-remote-range "ExternalData" (concat "@" "I+" "1"
"$" "1"))
@2$3='(org-table-get-remote-range "ExternalData" (concat "@" "I+" "1"
"$" "2"))
I was also able to concat the data from range @I+2$1..@II-1$2 using the
syntax shown in
https://orgmode.org/worg/org-tutorials/org-spreadsheet-lisp-formulas.html#org4a215c8
:
@>$2='(mapconcat 'identity (org-table-get-remote-range "ExternalData"
(concat "@" "I+" "2" "$" "1" ".." "@" "II-" "1" "$" "2")) " ")
However, the two things I would like to do are :
1) assigning the range to @3$2..@4$3 in table "MainData"
@2$2..@4$3 = '(org-table-get-remote-range "ExternalData" (concat "@"
"I+" "1" "$" "1" ".." "@II-" "1" "$" "2"))
I also tried '(identity (org-table-get-remote-range ...))
2) summing the range in a cell of "MainData"
@>$3 = '(+ (mapcar 'string-to-number (mapconcat 'identity
(org-table-get-remote-range "ExternalData" (concat "@" "I+" "2" "$" "1"
".." "@" "II-" "1" "$" "2")) " ")))
I first tried without the (mapconcat 'identity (...))
I entered the formula-debugger (for some reason, I can't C-c C-c in a
specific cell to evaluate that cell only), and this is the result I get
for evaluating (org-table-get-remote-range ...) :
(#("2" 0 1 (fontified t face org-table)) #("20" 0 2 (fontified t face
org-table)) #("3" 0 1 (fontified t face org-table)) #("30" 0 2
(fontified t face org-table)))
I don't know what kind of forms they are, or how I can get the data from
them.
I tried to "cadr" them, without luck.
Also, I see that after being (mapconcat 'identity (...)), they become :
#("2 20 3 30" 0 1 (face org-table) 2 4 (face org-table) 5 6 (face
org-table) 7 9 (face org-table))
Which shows, they are transformed in some way it is understandable in
the spreadsheet, but I don't know how it get transformed to that,
neither how the spreadsheet handles the extra arguments that seem
different thant the individual form of each argument gathered.
I also tried using "org-no-properties" somehow, but in the overall I am
just trying to guess what to do.
I don't understand much of the data I get, how to handle it, and what
the spreadsheet expects to get in the end.
Can you give me a hint for that, please ?
I would be greatful :)
