packages submissions : org-sql-session and org-blog

[Phil Estival]

Hello,

Here are two packages that I'd like to submit to ELPA, with
the advise and approval of emacs-devel.

- ob-sql-session : https://github.com/flintforge/ob-sql-session
   meant as a replacement for the orphan package ob-sql-mode.
   It's in decent state. Version 1.

- Org-weblog (that I may rename org-blog):
   https://gitlab.com/7dnz/org-weblog. Version 0.
   Written in literate programming, yet by a lisp beginner
   in that time.
     The documentation goes along with the program itself and
   they get both published as a static site.
   Demo here:  https://7d.nz/Blogging-with-org.html
   The code is quite long. This paragraph gives the overall idea:
   https://7d.nz/Blogging-with-org.html#Introduction.
   Has a lot of space for improvements, options and customization,
   but only a few for a v1.

Questions and Criticism are welcome,
along enthusiasm and motivation.

Cheers,

Phil

Hi Phil,

A quick, initial suggestion: it would be good to reformat the Lisp code 
in both projects, as I see several cases of incorrect indentation, 
hanging parens, extra blank lines, etc, and some of them would make the 
code hard to read.  For my Lisp editing, I use aggressive-indent-mode, 
which ensures that the code is always indented correctly.  For some 
other reformatting, Oleh Krehel's Lispy package has commands to help.

Also, for org-sql-session (which sounds very useful), it would be good 
to compare and contrast it with the package it's meant to supersede. 
And since it's meant to integrate with org-babel, it might be good to 
discuss its inclusion on the Org mailing list also.

Just to be sure, you mean GNU ELPA (not NonGNU ELPA), right?

I agree with Adam that the code is... etwas messy ATM.  Taking a moment
to reindent everything and perhaps add a .dir-locals.el file that
enforces a consistent code style would be of long-term use.

Hmm, I don't know if we have any literate programs on ELPA yet.  If you
prefer that style of development, that is fair, but what I would suggest
would be to add a Makefile and extract the elisp at "compile-time", or
in the case of ELPA when the tarball is being built.

Evaluating the expression in org-weblog.el gives me an error

  Debugger entered--Lisp error: (void-function org-weblog-auto-export-mode)

so I don't think that is ready yet.

Nevertheless, skimming through the .org file (which most certainly
should /not/ be the README btw) the code could also use some cleaning
up, at least if the intention is to publish it as a generic package.
The functions don't seem to adhere to a specific conventional namespace,

Occur on "defun" gives me:

The following comparison was added to the readme file.

ob-sql-mode :
- is very simple : forward the sql source through `sql-redirect'
- has a test suite
- but gives clunky output
- no :results table
- sql client shell commands messes up output
- prompt again for connection parameters when restarting a session

ob-sql-session :
- handle large results
- has :results tables
- accept header variables (:var)
- accept sql client shell commands
- keep login parameters
- prompt only for blank connection parameters
- can use `with-environment-variables'
- provide some more tests

I think so. The ownership transferred to the FSF and a copyright
assignment. One word about the license notice: I'm in agreement
with Stephan's opinion:
> historically we have accepted both "is part of GNU Emacs" and "is NOT
> part of GNU Emacs".  IMO the better choice is to say neither.

Understood. I'll be back with something cleaner, reconsider
where it can rely on the existing structures, and seek more advice
on the Org mailing list. Thanks for everything.

To be clear, this makes 3 implementations of SQL support for Org Babel 
that I know of:

1. The built-in Org Babel SQL support, aka ob-sql, documented at 
<https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-sql.html>

2. ob-sql-mode, hosted at <https://github.com/nikclayton/ob-sql-mode>, 
which advertises itself as "an alternative backend for Org-Babel SQL SRC 
blocks that uses sql-mode to evaluate the query instead of Org-Babel's 
built-in SQL backends."

3. Your new ob-sql-session library.

You've mentioned how your library compares to ob-sql-mode, but how does 
it compare to the built-in ob-sql library?

Thanks,
Adam

Here is a comparison with ob-sql-mode

ob-sql-session exists is for session support, which is in the TODOs
of ob-sql.

- ob-sql command execution relies on org-babel-eval
   (→ process-file → call-process).

- ob-sql-session runs an inferior process (in which
   sqli-interactive-mode can be activated when needed).
   The process output is filtered (e.g. results and prompts).
   When a session is demanded, this shell stays open for further commands
   and can keep a state (typically, when given special SQL commands).

ob-sql-session adapts sql-connect of sql.el by declaring
ob-sql-connect, in order to prompt only for missing connection
parameters.

- ob-sql defines org-babel-sql-dbstring-[engine]
    to be provided on a shell command line.

- likewise, ob-sql-session has to define
    - a connection string,
    - the prompt,
    - and the terminal command prefix
      for a every supported SQL client shell (or "engines")

- ob-sql-session requires sql.el.
   With the above defined, it should be compatible
   with most database of the sql.el's zoo. maybe.

Right.

Yeah, that is fine.

Thank you, and I hope my words were not too harsh.  I am not an
org-mode expert, perhaps the people on the org-mode mailing list might
have some comments and ideas on how to best implement your idea.

We can change this aspect of the license notice to fit the ways we
distribute that file.

If a file is part of Emacs, it should say so, and we should
write the notice as we do fo all the other files of Emacs.

If the file is NOT part of Emacs, meaning if it is distributed in
other ways separately from Emacs, them we could use the sort of
license notice that says "This program" and does not mention "GNU
Emacs".

Have you considered integrating it into ob-sql itself?
If not, what are the obstacles?

Hello Ihor,

yes I have. It grows ob-sql by approximately 300 lines.
There are rooms for improvements.
https://github.com/flintforge/ob-sql-session/blob/main/ob-sql.el

Current status :
- added support of :sessions to ob-sql.el, by merging ob-sql-session.el
- restored support for sqlite (even if there is ob-sqlite.el)
- added composite types for options
- moved options from org-babel to a new group org-babel-sql

TODO :
- use `org-babel-prep-session'
- verify headers and columns options
- check use and storage of :dbconnection
- minimize writings of temporary files
- Tests

Cheers,

Phil

Thanks for the update!
I will be looking towards your improvements to be merged upstream.
Feel free to ask me anything if you need any help.
