Re: Combining ob-sql, docker-tramp, and tramp ssh?
I have done something very similar, but with a few differences which might help. In my case, I didn't use tramp, but instead used ssh tunnels that I defined in my ssh config file e.g. Host wdb-dev HostName dev-example.com User fred LocalForward localhost:3330 localhost:5432 Host wdb-prod HostName prod-example.com User fred LocalForward localhost:3331 localhost:5432 This allows me to run psql using the -p switch to set the port e.g. 3330 or 3331 with same user name and database name. I then used sql's connection alist to define connection names for the different databases. You could probably use a .dir-locals.el file to do the same thing on a per directory/project basis. I would then open a terminal for each connection I needed and do ssh wdb-dev or ssh wdb-prod to setup the tunneling. The downside of this setup is that if you lose the ssh connection, you lose connection to the host and will need to restart it for things to work (where with the tramp setup it will make the connection when needed). The advantage is that I could use other tools, like psql or dbbeaver/pgadmin/whatever at the same time. If you want things to work in such a way that your org sql blocks all use the same database name, you can just adjust the ssh config to use the same port number, but then you can only have one connection active at a time. However, this means you can setup things to connect to your dev system, refine and test all your sql blocks and once confident they are working, just change the ssh connection to point to the prod system and re-run.

Combining ob-sql, docker-tramp, and tramp ssh?
I've been using ob-sql to document & prune our dev db and it's been amazing. https://media.discordapp.net/attachments/428916969861808130/768589313964507166/image0.gif The only rough edge has been that I have to expose the SQL ports to my host, forward it over ssh (I'm using a remote machine to offload docker resources), then install a version of psql required to connect. Lastly I then need to symlink psql to point to the targeted version of psql I need. This means I can only match one setup at a time. A preferred route would be to use the :dir property to eval over tramp like: #+begin_src sql :dir "/sshx:user@devbox|docker:user@vm:/src" SELECT count(id) from accounts; #+end_src If I use Python it works, but something specific about this combo is not working. Any suggestions to fix this, personal config, docs, or debugging steps one could point me to?
Re: Bug: Can’t assign to hline relative reference
In the case where I'm using this formula, there are many more rows between @I..@II. I only used two in the example to keep the email small. I would also be adding more rows regularly, making it slightly impractical to be adjusting the beginning and end points of the formula every time I add or remove a row. I appreciate your suggestion, though I was hoping for a more convenient solution. If nothing else works, that's what I'll do. I'd like to get to the bottom of why hlines aren't permitted in table formulas, it seems like something that should be allowed.

Re: [PATCH] org-table: Add mode flag to enable Calc units simplification mode
Hello,
after working on this I realized that the org-tbl-calc-modes variables
is used only locally despite being declare globally. Maybe a remnant
from pre-lexical-binding times. Attached is a patch (on top of the
others one in this thread) that simplifies things a little.
Cheers,
Dan

Subject: [PATCH 4/4] org-table: Remove unused org-tbl-calc-modes variable
* org-table.el (org-tbl-calc-modes): Remove the variable declaration
as the varialble is only used as a local variable in `org-table-eval-formula'.
* org-table.el (org-table--set-calc-mode): Drop convenience macro.
* org-table.el (org-table-eval-formula): Rename `org-tbl-calc-modes`
local variable without the org-table prefix and usr the gained screen
real estate to avoid indirection through covenience macro.

Bug: org-insert-heading-respect-content before first heading [9.4 (9.4-19-gb1de0c-elpaplus @ /home/gustavo/.emacs.d/elpa/org-plus-contrib-20201019/)]
Hi All,
I just found a misbehaving of `org-insert-heading-respect-content': when
it's called before the first heading in the buffer, it breaks the
structure of that fist heading by inserting a new heading on the line
the previous heading existed.
An ECM to reproduce the issue is:
- Start 'emacs -Q'
- Do an initial setup:
#+begin_src emacs-lisp
(add-to-list 'load-path "~/.emacs.d/elpa/org-plus-contrib-20201019")
#+end_src
- Visit file =test.org= with contents:
#+begin_src org
,#+title: Title
,* Foo
#+end_src
- Place point between the title and the "Foo" heading, and call
`org-insert-heading-respect-content' with "C-RET".
- The result is:
#+begin_src org
,#+title: Title
,* !* Foo
#+end_src
where "!" represents point position.
Which clearly does not "respect content" of the following heading.
Best regards,
Gustavo.

Re: Bug: Can’t assign to hline relative reference
This seems to be related to: https://emacs.stackexchange.com/questions/15185/cant-assign-to-hline-relative-reference There seem to be restrictions regarding hline-relative-references within table-formulas.

I think this can already be done. imports can be added to the headers, and
babel allows file-wide headers, so you could add a =#+HEADER: :import
rx.Observable= line to the file and all source blocks would get it. it's
slightly different in that =org-babel-java--import-maybe= skips imports
that it thinks aren't needed. also if there are any non-java source blocks
in the same file, these imports could be added to them which would be bad,
so when mixing multiple languages in the same file this wouldn't be an
option.

Thanks for fixing the spacing. I don't think I can give you credit for the
patch, though, without leaving it out until ob-java is accepted.

Interview with Rainer König - who's content made me go from vim to emacs for coding :D
Today I had the chance to do a lengthy interview with Rainer König who is known for creating a very popular Org Mode course. The first part is about how Rainer got started and the story of how Org Mode saved his life during a very difficult time: https://www.youtube.com/watch?v=L_DYO0_eJ6A In the second part of the interview we look at how Rainer manages his org mode setup with multiple files and weekly reviews. Rainer is tremendously methodical and a really good teacher. Here is the recording of the second part: https://www.youtube.com/watch?v=kPKhS-QDn7c Enjoy! -- Best regards, *Martin Schröder* *Embedded Systems Consultant, Firmware Expert* Tel: +46-733-38-76-94 LinkedIn: https://www.linkedin.com/in/martinschroder/ *Learn How To Build Embedded Products From Step 1 to Step 90:* https://swedishembedded.com/learn/
Re: [PATCH] ob-java
I did and it looks really good. The difference in this example:
#+BEGIN_SRC java
import rx.Observable;
Observable.range(5, 3)
.subscribe((Integer i) -> { System.out.println("Got: " + i); },
(Throwable t) -> { t.printStackTrace();},
() ->{ System.out.println("Ending stream"); });
#+END_SRC
from the ones I posted yesterday is tremendous!
I am not very experienced with Emacs lisp but I think it's pretty easy
to understand how things works and follow the code. The comments are
also of good help. I really appreciate the work you have done!
What do you think about having a configurable list where the user can
add =org-babel-java--import-maybe=? In my current use case I could then
add RxJava imports to that list and the imports could be removed from
the source code block.

Some spacing when writing =public static...=
