ediprolog 2.2 is now available from:

    https://www.metalevel.at/ediprolog/ediprolog.el

New in this version:

    * handle answers of recent Scryer Prolog versions
    * faithful processing of multiline queries when using Scryer Prolog
    * improved compatibility with older Emacs versions

Project page:

    https://www.metalevel.at/ediprolog/

Video demonstration:

    https://www.metalevel.at/prolog/videos/ediprolog

For completeness, I also include a copy of the source code below.

Could you please upload the new release to ELPA?

Thank you a lot!
Markus

;;; Commentary:

;; These definitions let you interact with Prolog in all buffers.
;; You can consult Prolog programs and evaluate embedded queries.

;; Installation
;; ============
;;
;; Copy ediprolog.el to your load-path and add to your .emacs:
;;
;;     (require 'ediprolog)
;;     (global-set-key [f10] 'ediprolog-dwim)
;;
;; Restart Emacs and customize ediprolog with
;;
;;     M-x customize-group RET ediprolog RET
;;
;; The two most important configuration options are:
;;
;;    - `ediprolog-system', either 'scryer (default) or 'swi
;;    - `ediprolog-program', the path of the Prolog executable.

;; Usage
;; =====
;;
;; The central function is `ediprolog-dwim' (Do What I Mean), which is
;; bound to F10 by the snippet above. Depending on the content at
;; point, `ediprolog-dwim' does the "appropriate" thing: If point is
;; on a query, F10 sends the query to a Prolog process, and you
;; interact with the process in the current buffer as on a terminal.
;; Queries start with "?-" or ":-", possibly preceded by "%" and
;; whitespace. An example of a query is (without leading ";;"):
;;
;;   %?- member(X, "abc").
;;
;; If you press F10 when point is on that query, you get:
;;
;;   %?- member(X, "abc").
;;   %@    X = a
;;   %@ ;  X = b
;;   %@ ;  X = c
;;   %@ ;  false.
;;
;; When waiting for output of the Prolog process, you can press C-g to
;; unblock Emacs and continue with other work. To resume interaction
;; with the Prolog process, use M-x ediprolog-toplevel RET.

;; If you press F10 when point is *not* on a query, the buffer content
;; is consulted in the Prolog process, and point is moved to the first
;; error (if any). In transient mark mode, if the region is active,
;; only the text in the region is consulted.

;; For convenience, the most recent interactions with the Prolog
;; process are logged in the buffer "*ediprolog-history*".

;; Use M-x ediprolog-localize RET to make any Prolog process started
;; in the current buffer buffer-local. This way, you can run distinct
;; processes simultaneously. Revert with M-x ediprolog-unlocalize RET.

;; `ediprolog-dwim' with prefix arguments has special meanings:
;;
;;   C-0 F10       kill Prolog process
;;   C-1 F10       always consult buffer (even when point is on a query)
;;   C-2 F10       always consult buffer, using a new process
;;   C-7 F10       equivalent to `ediprolog-toplevel'
;;   C-u F10       first consult buffer, then evaluate query (if any)
;;   C-u C-u F10   like C-u F10, with a new process

;; Tested with Scryer Prolog 0.8.119 and SWI-Prolog 8.1.24,
;; using Emacs versions 26.1 and 27.0.50.

We normally prefer to get the full VC history of package in ELPA instead
of doing updates like this, but I guess doing it this way would be fine,
too.

I've added Stefan to the CCs; perhaps he has some comments.

Could you make that available on a public Git repository somewhere
(eg. `repo.or.cz`, `codeberg.org`, ...)?

Yes, I have made a public repository available at:

    https://github.com/triska/ediprolog/

The history of ediprolog.el is available from:

    https://github.com/triska/ediprolog/commits/master/ediprolog.el

The changes relative to 2.1 are:

    https://github.com/triska/ediprolog/commit/5fd08fe19a71876da4cfc21b81fbc04af9890cba
    https://github.com/triska/ediprolog/commit/85fae67aeaede36ba61b0c551aa18617d3b9f797
    https://github.com/triska/ediprolog/commit/ebd79c0abdc05a752c947e333551d808e3933046
    https://github.com/triska/ediprolog/commit/dc0e51ba579f2eb26ae0cdc733104e8861f04c10

The release of 2.1 was:

    https://debbugs.gnu.org/cgi/bugreport.cgi?bug=41765

Please let me know if anything else is needed.

Thank you and all the best,
Markus

Could you merge that history with that of elpa.git?
I.e. start with

    git remote add -p externals/ediprolog elpa \
               git://git.sv.gnu.org/emacs/elpa.git

and then try something like

    git merge elpa/externals/ediprolog

It might be rather messy done this way.  You may need to start by
merging the elpa history with the closest matching version in your
history (maybe commit 751119cfee9efb52e89d0387d795f3b0c181299d?):

    git reset --hard 751119cfee9efb52e89d0387d795f3b0c181299d
    git merge elpa/externals/ediprolog
    [ resolve any conflicts, and make any other changes you like ]
    git merge

elpa.git won't be able to follow your repository until that repository's
HEAD is a "fast forward" so this "merging" is necessary.  You can make
it "trivial" by throwing away any and all changes that actually come
from `elpa/externals/ediprolog`: only the metadata needs to say that
the commits of `elpa/externals/ediprolog` have all been merged.


        Stefan

OK, I have uploaded the changes as a series of patches at:

    https://www.metalevel.at/ediprolog/ediprolog_2_2.patch

For completeness, I also attach the content at the end of this mail, and
I hope this suffices to update the package?

Thank you and all the best,
Markus

No, that's not what I'm after.  I want `git merge` to work.  So I need
you to merge that specific commit into your upstream repository so that
elpa.git can then follow your repository.  The important part is all in
the *meta*data, not in the file's contents.

Due to other commitments, I unfortunately cannot help further with these
issues which seem very complex to me (I do not even know what you mean
with the *meta*data). If what I provided unexpectedly no longer suffices
to upload the latest release to ELPA (in all previous releases,
announcing the newest version sufficed), could you please remove
ediprolog from ELPA? It seems best not to provide an outdated version.

Thank you and all the best,
Markus

The metadata is the info Git saves about the history of the package.
It uses it for example to know how to do an update when you fetch updates.

If you need help with Git I can do that.

I just did the merge I suggested and the result is in the
`scratch/ediprolog` branch in `elpa.git`.

So all you need to do is to merge that code into your repository, is
the following:

    cd .../where/you/keep/your/clone/of/ediprolog/
    git fetch --single-branch scratch/ediprolog git://git.sv.gnu.org/emacs/elpa.git
    git merge FETCH_HEAD

and then `git push` the result to your repository.

I appended below my signature the changes that this `merge` will apply
to your code (beside the changes to the metadata).  The `.gitignore`
file is not indispensable but is very handy for other people using your
Git repository (or its mirror in elpa.git), but the other two changes
are indispensable because GNU ELPA needs the `Version:` header to know
what is the version of your package (and when a new version is
released), and it checks the copyright headers which state that the
files are covered by copyright assignments.

Sorry, that should have been:

    cd .../where/you/keep/your/clone/of/ediprolog/
    git fetch git://git.sv.gnu.org/emacs/elpa.git scratch/ediprolog 
    git merge FETCH_HEAD

I mixed up the syntaxes for `git fetch` and `git clone`.

Hi,

Could you do:

    cd .../where/you/keep/your/clone/of/ediprolog/
    git fetch git://git.sv.gnu.org/emacs/elpa.git scratch/ediprolog 
    git merge FETCH_HEAD

so as to merge the few minor changes we had over in elpa.git?
It will make 2 changes:

- Change copyright line to make it compatible with GNU ELPA requirements.
- Add a `Version: 2.2` header line so GNU ELPA can make a release of the
  new code.
- Tell Git that those changes have been merged, so it can properly track
  future changes from your repository.

Thank you! Please do keep these changes in the ELPA version of the file,
since they are specific to ELPA. The git repository of ediprolog
provides the master copy of ediprolog.el, and I will keep it as it is.

In a previous mail in this thread, I have provided a patchset relative
to the current ELPA version of ediprolog.el that incorporates all latest
developments from the master version which I provide on the ediprolog
page and also on github. If possible, please use the patchset to update
the ELPA version, and make any ELPA-specific adjustments as necessary.

Unfortunately I cannot help further, so I hope this suffices.

Thank you and all the best,
Markus

Hi Markus,

> since they are specific to ELPA.

I don't see why you think they are specific to GNU ELPA.

E.g. the `Version:` header is a convention followed by most packages
nowadays and used by various tools, whereas your `ediprolog-version`
variable is not used even by your code (or doc).

> The git repository of ediprolog provides the master copy of
> ediprolog.el, and I will keep it as it is.

So you do not want to add a `Version:` line and you do not want to
change the copyright line to say that it is owned by the FSF?

Could you explain why?

The `git merge` dance I'm asking you to do is expected to be a one-time
occurrence, not something that you'll need to do for every release.

[ BTW, you've signed the copyright paperwork which transferred the
  copyright to the FSF, so you technically do not own the copyright to
  that file any more, so your upstream code's copyright line is
  incorrect.  ]

There are enough packages in (Non)GNU ELPA that we try to avoid such
manual work.  Instead changes are automatically pulled from upstream
repositories and new packages are released without further human
intervention.  More specifically the only human intervention needed to
cause a new release is the upstream maintainer's modification of the
`Version:` line.

The jurisdiction where I reside guarantees authors' rights as opposed to
copyright. Certain rights I have as the sole author of ediprolog.el
cannot be transferred, except by inheritance, even if I wanted to
transfer them (§ 23 Abs. 3 UrhG). The rights I have as the author of
ediprolog.el include the right to decide whether and how to display that
I am its author (§ 20 Abs. 1 UrhG).

In the master file of ediprolog.el, I am using the copyright notice as
the usual way ("übliche Weise") in which authorship is indicated in
code. This is to satisfy the conditions of § 12 UrhG to indicate me as
the author of the code. Since I am the author, the notice it correct.

I have the rights I mentioned also without this notice, and therefore I
accept changes you make to this notice if they are required to
distribute ediprolog.el on ELPA. The master file I provide in the
jurisdiction where I reside will retain the notice for the reason above.

Thank you and all the best,
Markus

Yes, they use different names, but they work pretty much in the same way.

The same for copyright law in North America.  They're just called
differently, but by and large they work the same.

Fine, then it's not technically incorrect, but it's still inconvenient
for us and it's misleading when interpreted based on the meaning of
those words in some other jurisdictions.  In contrast, you also have

    ;; Author: Markus Triska <triska@metalevel.at>

in that file, which should be very clear to everyone and makes your
copyright line redundant (in addition to inconvenient for us and
misleading in some contexts).

If all authors of all GNU ELPA packages were to ask for special
treatment for their pet detail, I'd have given up on GNU ELPA
a long time ago.

I added a hack in GNU ELPA's scripts to deal with the third point, but
the other two are still a problem:

- As long as you use another copyright line, every time you make a change
  to that line, the automatic merge will fail because of a merge
  conflict, so it will require manual intervention.

- As long as you don't use the `Version:` header, the scripts won't know
  when you want to make a new release, so again manual intervention will
  be needed every time you want to make a release.

Could you please please pretty please help me reduce my workload by
avoiding those needs for human intervention?

The best way you can do that is:

    cd .../where/you/keep/your/clone/of/ediprolog/
    git fetch git://git.sv.gnu.org/emacs/elpa.git scratch/ediprolog

Actually, now a better choice would be:

Thank you, I will look into this! One remaining issue I noticed is that
the formatting of the ELPA description page seems to be a bit broken
now, in particular (1) the result of the sample query and also (2) the
table showing the key sequences on this page:

    https://elpa.gnu.org/packages/ediprolog.html

For comparison, this is how the page looked previously:

    https://web.archive.org/web/20211016152552/https://elpa.gnu.org/packages/ediprolog.html

Note that the answer to the sample query is correctly formatted
(spanning multiple lines), and the table of key sequences is also shown
very readably.

Why does this issue arise, is this an issue of Markdown rendering, and
can I do anything to display the page as intended?

Thank you and all the best,
Markus

Hmm... that looks quite odd indeed.  Looks like a bug in the markdown
rendering into HTML or a side-effect of the CSS we apply to it.

This one is normal/expected: we currently only support the "plainest"
markdown, not extensions like tables.

If you happen to know a bit about HTML, it would help if you looked at
the generated HTML for the query result and tell me if the problem is in
the HTML itself or the CSS applied to it.

And if you know about markdown processors, it would help if you could
provide guidance as to which one to use and how to configure it so it
only supports a limited set of extensions (I'd rather not get tied to
a particular set of extensions only supported by a particular processor,
which is why I currently use the no-frills `markdown` from the
`markdown` Debian package).

It seems like the "markdown" package is now orphaned in Debian:

    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=466330

That package seems to have been in life support for a decade or more,
based on the Debian changelog and the above discussion.

How about using python-markdown instead?  It seems to be actively
maintained and no-frills enough.  See:

    https://python-markdown.github.io/#goals

It has optional extensions, such as one for tables.

Apparently it's a problem in the CSS.  I installed a change which seems
to fix it, but there's probably a more elegant and reliable way to do it.

I ended up using https://github.com/trentm/python-markdown2
instead.  The choice was largely arbitrary, but markdown2 was smaller,
claims to be faster, and had one less dependency.

So, from now on, tables should start working (not in existing pages,
tho: it'll only start working after a new tarball gets built).

How about adding markdown support to core instead?  It shouldn't be
hard to whip up a decent markdown mode for Emacs, and I recently
learned that Eglot works much better when such a mode is available.

Sounds good to me, tho I'm not sure about the "instead": the discussion
to which you replied related to the code used to generate the HTML files
for elpa.gnu.org, whereas a "Markdown support in core" may not
necessarily support the generation of HTML (and would instead focus on
rendering Markdown into an Emacs buffer).

Thank you a lot! I the meantime, I noticed a few additional issues:

  1) Text that is intended to be bold is sometimes not shown in bold. For
     example, even though line 76 of README.md starts with:

       Use **M-x ediprolog-localize RET** to make any Prolog process

     the text 'M-x ediprolog-localize RET' is not displayed in bold.

  2) The link to ediprolog.el (line 23 of README.md) does not work.

  3) The image in line 101 of README.md is not shown.

Do you think they can also be solved, so that they work as intended?

Thank you and all the best!
Markus

I think this is fixed now, thanks.

Relative links don't work, indeed.  I don't know how we could/should fix them.
We don't actually have an `ediprolog.el` file nearby in the website.

In this particular case, I think the better option is just to remove the
link and the whole discussion of how to install it, since that's the
same as for all other packages :-)
[ And some of that info is already mentioned earlier in
  https://elpa.gnu.org/packages/ediprolog.html ]

>   3) The image in line 101 of README.md is not shown.

I think it's the same problem that the relative link to `factorial.png`
fails.  The case is a bit different in the sense that I can't argue this
time that the link is redundant anyway :-)

Maybe we could try and recognize those links and redirect them to something like
https://git.savannah.gnu.org/cgit/emacs/elpa.git/plain/factorial.png?h=externals/ediprolog
but going through `cgit` is rather inefficient (and recognizing those
links reliably is not completely trivial either).

We could just copy any image files to the web directory, and add some
heuristics to change any <img>-tags in the HTML (exported from
markdown2, org-mode, etc.) to point there.

For example, we could put factorial.png in
/images/<package-name>/factorial.png.  The only cost is a bit of
diskspace, but it shouldn't be a lot as there is already some incentive
to keep down file sizes.

But the page which links to it is not inside `/images/<package-name>/`
so the relative link will still fail.

I think we need to first move the packages's webpages from

   https://elpa.gnu.org/packages/<PKG>.html

to

   https://elpa.gnu.org/packages/<PKG>/index.html

and then we can more easily copy image files and anything else to
that subdirectory.

We have similar needs for the HTML-rendered `:doc`s which are placed into
https://elpa.gnu.org/packages/doc/<MANUAL>.html so we'd also want to
copy somefiles to that `doc` subdir.  The problem is a bit worse there,
because that subdir is shared between all the packages so as to make it
possible to have relative links between manuals of different packages.
IOW we probably need to enforce that all the files that need to be
copied into the `doc` subdir are prefixed by the package name.

I was thinking of using absolute but domain-specific links, i.e. moving
all images to the directory:

    $WEBROOT/images/<package>

And then changing the img-tags to read:

    <img src="/images/<package>/<image>">

That way, we don't need to worry about relative links.  So, for example,
if we have an image named "screenshot.png" in the repository for
<package>, and it looks something like this in the raw HTML export:

    <img src="https://cdn.github.com/foo/bar/screenshot.png">

We replace everything before the last "/" with "/images/<package>", or
indeed just add it there if the link is relative, so we end up with:

    <img src="/images/<package>/screenshot.png">

Does that make sense?

That's another option, yes.  That would allow us to use relative links.

Do we anticipate more things going in that directory, too?  Perhaps some
packages will ship with some non-documentation resource files that don't
belong in $WEBROOT/doc?  If so, this option might be cleaner in the long
run.

It would also make for slightly shorter "home URL".

All the old compressed tarballs would move there too, yes.  And also the
output for `:doc` (which currently lives in a `.../doc/<package>/`
subdir instead).

It seems like ediprolog 2.2 was uploaded to GNU ELPA on 2022-Oct-26.
Belayed congratulations on the new release.

I'm consequently closing this particular bug report.  Please let me know
if that doesn't make sense for some reason and we can reopen.

Several issues I mentioned in this thread still persist. For example,
the page is not formatted as intended, and the image is not
shown. Please see the discussion in this thread for more information.

Thank you and all the best,

Thanks.  I'm concerned that those issues will get lost in the noise in
this bug, which is currently titled "27.0.50; ediprolog 2.2: Please
upload the new version to ELPA".  For boring reasons, including
limitations in debbugs, it's not easy for me to change the title.

Does it make more sense to open new bugs to track those issues (thereby
making them more visible), or should we simply reopen this one?

Personally, I would suggest you reopen this issue until you are certain
about how to best proceed: In this way, the mentioned remaining problems
are not forgotten, and I do not unnecessarily open more issues.

Thank you and all the best,
Markus
