Hi,
I want org-mode to display a tab-separated values table ge-
nerated by jq that includes elisp links that do something
(differently) for each row, especially containing data that
is not displayed in other columns.
The source block:
| #+BEGIN_SRC sh :colnames '(Column\ A Column\ B Column\ C)
| jq --null-input -r 'range(1; 4) | tostring | [ "A" + ., "B" + .,
"[[elisp:(ignore)][Do it]]"] | @tsv'
| #+END_SRC
evaluates to:
| #+RESULTS:
| | Column A | Column B | Column C |
| |----------+----------+----------|
| | A1 | B1 | [[elisp:(ignore)][Do it]] |
| | A2 | B2 | [[elisp:(ignore)][Do it]] |
| | A3 | B3 | [[elisp:(ignore)][Do it]] |
which org-mode displays as:
| #+RESULTS:
| | Column A | Column B | Column C |
| |----------+----------+----------|
| | A1 | B1 | Do it |
| | A2 | B2 | Do it |
| | A3 | B3 | Do it |
with each "Do it" being a button that, when pressed and con-
firmed, executes ignore. Great!
Executing Emacs Lisp:
| (org-insert-link nil "elisp:(ignore \"1\")" "Do it")
results in the org-mode source code:
| [[elisp:(ignore "1")][Do it]]
so let's try jq generating that with:
| #+BEGIN_SRC sh :colnames '(Column\ A Column\ B Column\ C)
| jq --null-input -r 'range(1; 4) | tostring | [ "A" + ., "B" + .,
"[[elisp:(ignore \"" + . + "\")][Do it]]"] | @tsv'
| #+END_SRC
This jq call, executed in a shell, evaluates to the output
(tab-separated):
| A1 B1 [[elisp:(ignore "1")][Do it]]
| A2 B2 [[elisp:(ignore "2")][Do it]]
| A3 B3 [[elisp:(ignore "3")][Do it]]
When org-mode evaluates the source block, it strips it down
to:
| #+RESULTS:
| | Column A | Column B | Column C |
| |----------+----------+----------|
| | A1 | B1 | 1 |
| | A2 | B2 | 2 |
| | A3 | B3 | 3 |
where "1", "2" and "3" are not buttons or anything else but
plain text, and any other input has been permanently dis-
carded (i. e., is not just not displayed).
If however I set ":results raw" in the source block:
| #+BEGIN_SRC sh :colnames '(Column\ A Column\ B Column\ C) :results raw
| jq --null-input -r 'range(1; 4) | tostring | [ "A" + ., "B" + .,
"[[elisp:(ignore \"" + . + "\")][Do it]]"] | @tsv'
| #+END_SRC
org-mode evaluates that to:
| #+RESULTS:
| A1 B1 Do it
| A2 B2 Do it
| A3 B3 Do it
with each "Do it" being a button that, when pressed and con-
firmed, will execute (ignore "1"), (ignore "2") and (ignore
"3"), respectively.
So in the first and third source block, org-mode teases me
that I can embed elisp links in that very nice table format
(first source block) with "complex" Lisp code (third source
block), but when I try to combine the two (second source
block), it slaps me in the face.
Surely I must be missing some obvious solution? Is there
another syntax I need to use? Do I need to have jq output
the raw columns A, B, D and E and then define a :post source
block that converts that to A, B and C = f(D, E)?
My alternative and thus benchmark for such "dashboards" that
show "stuff" and offer things to do with it are derivatives
of tabulated-list-mode, but their programming requires de-
finitions of functions & Co. that need to be updated syn-
chronously; an org-mode source block on the other hand just
does what it says on the tin.
TIA,
Tim
