You can (add-to-list 'desktop-locals-to-save 'mark-ring) and it works, so long as you have the fix for bug 13951 applied. But it's very verbose; for each element of mark-ring for each buffer, it writes an entry like

(let ((mk (make-marker))) (add-hook 'desktop-delay-hook (list 'lambda '() (list 'set-marker mk 123 '(get-buffer "init.el")))) mk)

The result is about 2kB of text to record a standard 16-element mark-ring. The file name is redundant, since it's already written as the first argument for desktop-create-buffer, and the rest of the line could be eliminated by special-casing saving of mark-ring, leaving just a list of marker positions to write into the desktop file, which will typically be less than 100 bytes of text. If you have dozens of file-visiting buffers, this can make the difference between a desktop file that's over 100kB and one that's just a few kB.

The attached patch does this. Surely this qualifies as a tiny change, since it only changes about 5 significant lines.

The "&rest _unsupported" is unnecessary; it just enables forward compatibility with files of version greater than 207. If it were already there, then version 206 code would be able to read version 207 files, and just ignore the mark ring.

Returning result from desktop-create-buffer is unnecessary for desktop mode, but it does no harm, and I need it in some of my other code, so please allow it.

Having special-case code to print&read some variables is not in itself
a bad idea, but I think we should do it via a table mapping variables to
ad-hoc massaging functions.

Ok. Updated patch attached below.

This is more complex than my original patch, but it does what you want (IIUC what you want).

I forgot copy-marker existed. Updated patch attached.

FYI I'm not a committer, so I'm only sending my patches to the mailing list.

	It doesn’t look like a common abbreviation, so I guess

I wasted an hour today re-discovering the fact that (eval (car (get 'foo 'standard-value))), not (default-value 'foo), returns the default value of 'foo. I learned this lesson before, but the word ‟default” is so suggestive of meaning «default» that I forgot that it doesn't actually mean «default» in Emacs. I even remembered setq-default, but cognitive dissonance from the absurdity of its name prevented me from remembering that default-value has the same problem.

For the value of a symbol in the global context, how about using the word ‟global”?

Ask any normal English-speaker for an antonym of ‟local”. He won't say ‟default”. He'll say ‟remote” or ‟global” or some such.

Ask him for an antonym of ‟default”. He won't say ‟local”. He'll say ‟non-standard” or ‟customized” or some such.

Inflict Emacs upon him for a few months, then ask him what's the difference between a ‟standard value” and a ‟default value”. He won't know. Even after writing a thousand lines of Elisp.

Tell him that the default value of shift-select-mode is t. Then do (setq shift-select-mode nil), and ask him what the default value is. He'll say ‟t”, not ‟nil”. Ask him what changed, and he'll say shift-select-mode is no longer set to the default value. Then show him what (default-value shift-select-mode) returns, and he'll tell you it must be a bug.

Since ‟default” is already misused to mean «global», it can't be changed to mean «standard», since that would cause even more confusion. ‟Standard” can stay the way it is. ‟Buffer-local” can too. But please stop using the word ‟default” for «global»; use ‟global”. There's already precedence in Emacs: describe-variable calls it ‟global”.

Yes, but I intentionally avoided those terms because this table is for functions that don't necessarily just print and read in the normal Lisp sense. E.g. mark-ring contains markers, and a marker contains both a position and a reference to the relevant buffer, so simply printing mark-ring in the Lisp sense would involve printing both the positions and the buffer references, but its serializer function in this table outputs only the positions. The entire point of my patch is to avoid the Lisp sense of printing, because printing the buffer references is far too verbose.

> It doesn’t look like a common abbreviation,

It's a common abbreviation for parallel↔serial conversion circuits, which are reasonably analogous to functions that convert program data to/from a text stream. And circuitry is a domain for which it's common to share terminology with software.

> so I guess
> “serializer, deserializer” should rather be spelled in full.

This table is something that only programmers, not users, will need to understand or modify, so using a technical abbreviation isn't a problem. Emacs already has abbreviated names such as ⌜fboundp⌝ and ⌜fmakunbound⌝ for programmer-only things, instead of ⌜function-bound-predicate⌝ and ⌜function-make-unbound⌝. So if anything, ⌜funs⌝ isn't abbreviated _enough_. ;-)

Spelling out ⌜desktop-variable-serialization-deserialization-functions⌝ would be ironic, considering the purpose of my patch.

BTW, you quoted only me, but you CCed only Stefan. I almost missed your message, until I checked the mailing list.

	Incidentally, reading and development of digital circuits is one
	of my hobbies.  Yet, I don’t think I’ve ever seen such an
	abbreviation before in that domain, either.

	Still, their respective docstrings spell the term in full:

(fboundp SYMBOL): Return t if SYMBOL's function definition is not void.
(fmakunbound SYMBOL): Make SYMBOL's function definition be void.

	Contrary to the docstring proposed.

I tend to agree.  This "default-value" and "setq-default" dates back
to the very beginning of time, tho.

Would renaming them be acceptable, so long as the old names are kept as aliases for backward compatibility? I don't think the names ⌜global-value⌝, ⌜setq-global⌝, and ⌜set-global⌝ would cause any confusion with any other concepts in Emacs, and they're unlikely to conflict with anybody's custom code.

Please don't add new abbreviations.  The docstring and/or comments can
indicate that "serializer" stands for both directions if you really
need a shorter variable name.  Or use "serialization", which is
somewhat more ambiguous about including "deserialization".

I thought your patch was a refactoring.  That doesn't necessarily mean
code (or code components) are shorter, although it's often a happy

Please don't.  Buffer-local values are global values in the usual
sense that they are instance-wide and can be accessed in local context
if not shadowed by let-bindings and the like.  I understand your
mileage varies, but I don't think it's a big enough improvement to
justify having an alias, with neither being deprecated.  And I
definitely don't think it's a big enough improvement to justify
obsoleting the "default" versions.

Function parameters (or a closure's parameters and environment variables) are global variables in the sense that they're ‟instance-wide” (within the entire function or closure) and can be accessed in local context if not shadowed by let-bindings.

But «within an entire function or closure» isn't really instance-wide? Well neither is «within an entire buffer».

The global environment is the outermost one. A buffer's environment is not. There's only one global environment. There can be multiple buffers and multiple closures, each with its own environment. ‟Buffer-local” is a perfectly good term for buffer-locals. Calling them ‟global” would be misleading, and it's good that Emacs doesn't do that.

‟Global” is the right term for globals.

We are not talking about "within an entire buffer".  Emacs has a notion
of a "current buffer".  There is no hierarchy or stack or nesting
involved: the current buffer setting swaps out variables in global
scope.  It does not matter which module or buffer or context your global
variables have been defined in.

> The global environment is the outermost one. A buffer's environment is
> not.

That confusion seems to be the most compelling reason _not_ to mess with
the terminology in order not to cause additional confusion.  A buffer
does not have an "environment".  It has a list of global variable values
to substitute whenever it is made current.  There is always exactly one
current buffer.  You cannot _not_ have a current buffer:

emacs -Q --batch --eval '(message "%S" (current-buffer))'
#<buffer *scratch*>

And buffer-local variables _are_ buffer-local versions of _global_
variables.  They are not scoped.  With setq-default you are not setting
a value that is in any manner more or less global than a buffer-local
setting.  It is a separate symbol slot only accessible via special
commands or when no buffer-local setting exists.

What do you call the thing that lists the bindings of buffer-local variables to values? The standard term for a list of bindings of variables to values that's used for resolving variable references, both in Lisp and elsewhere, is ‟environment”.

You mean like a closure can have? (A closure's environment can also have variables with names that aren't names of global variables, but that's not the point here.)
(setq foo
      (lexical-let ((shift-select-mode 'bar))
	(lambda () shift-select-mode)))

shift-select-mode above is a closure-local version of a global variable.

setq-default sets the global variable, which is visible in other buffers (unless they shadow it with their own buffer-locals).
A buffer-local variable is not visible in other buffers.

I don't know how buffer-locals are implemented internally, but from a user's (and Elisp programmer's) point of view, a buffer has an environment with variables that shadow global variables. If the value of each variable in that environment is stored as part of the structure that stores the value of the same-named global variable rather than being stored in a separate list of bindings for the environment, that's irrelevant. The effect is the same.

The help system agrees with me. It doesn't call buffer-locals ‟global”. It _contrasts_ buffer-locals and globals. E.g. describe-variable for mark-active tells me:
mark-active is a variable defined in `buffer.c'.
Its value is t
Local in buffer *Help*; global value is nil

Look what happened when I proposed changing the names of set-default, setq-default, and default-value. They're misleading, but you and Eli say they're too old to change. IOW, bugs with seniority are features.

The names of car and cdr are even older. And they're not misleading; they're just archaic. There's both less need and less ability to change them than there is to change the former three.

And yes, the abbreviations ⌜cons⌝, ⌜fboundp⌝, and ⌜fmakunbound⌝ are old, but they're neither misleading nor archaic. I'm a good benchmark, since I'm easily fooled by misleading names and I have bad memory, yet these names don't cause me problems.

Closures nest.  Buffers don't.  And there always is one current buffer.
Closures are part of a lexical environment.  Buffers aren't.

Not at all.  It is not related to the global variable in any way.  If
you do
(disassemble (byte-compile foo)) you get

byte code:
  args: (&rest --cl-rest--)
0	constant  apply
1	constant  <compiled-function>
      args: (G42200)
    0	    varref    G42200
    1	    symbol-value 
    2	    return    

2	constant  --shift-select-mode--
3	varref	  --cl-rest--
4	call	  3
5	return	  

which is rather awful.  But the salient point is that
--shift-select-mode-- is a generated symbol (with value 'bar) not in any
way related to the global variable shift-select-mode.

The default value and the global value are part of the same symbol and
accessed with different commands.

Again, the buffer does not provide scoping.  It is the setting of
(current-buffer) that decides which buffer-local values are active.

There is no nesting of scopes involved here.  At any given time, only
one buffer's global variable are active.  That is similar to global
static variables in C: they are not nested.  Instead, one compilation
unit at a time may provide a value.  C does not have defaults for global
static variables: it is an error to declare the same name as global
external and global static.

Elisp, in contrast, provides two value slots for that purpose.

It does not seem like a good idea to spread the confusion, however.

I have my problems seeing how "Contents of address register" and
"Contents of decrement register" are accurate concerning the current
implementations.  In their _archaic_ sense, those terms are not
accurate.  It's just that they have grown into terms of their own.

> There's both less need and less ability to change them than there is

In contrast to car/cdr however, the _default_ value is still an accurate
description.

> And yes, the abbreviations ⌜cons⌝, ⌜fboundp⌝, and ⌜fmakunbound⌝ are
> old, but they're neither misleading nor archaic.

fboundp is sort of an archaic feature of the language.  Lisp symbols
have 4 slots by default: value, function value, property list, name.

In Scheme, symbols don't have any slot.  They are semantically the same
as keywords, just being an internment of their name.  That makes it
possible to implement a module system establishing the relation between
symbols and values in the _global_ lexical space.

> I'm a good benchmark, since I'm easily fooled by misleading names and

The problem is that you consider yourself the only benchmark, not just
for the naming but also for the meaning and implementation of terms.
That's not unusual for programmers, which is why there are regularly
scheduled shouting events under the title of "standards committee".

With regard to Emacs Lisp, we don't have such official events.

If you define nesting to be a required attribute of environments, then of course, by definition, things that don't nest aren't environments. But it seems strange to define them that way. Maybe this is a basic computer science truth I just missed.

How about a language that provides only global variables? No locals of any kind. Would you say that its global ‟environment” isn't really an environment, because there's nothing to nest it in or nest in it?

For Elisp, although buffers' environments can't nest in other buffers' environments, they do nest in something (the global environment, which I guess you would call the ⌜default environment⌝), and there are environments (of closures) that can nest in them. You can have a global variable, shadowed by a buffer-local, shadowed by a closure-local.

> Closures are part of a lexical environment.  Buffers aren't.

An environment can only have one binding for a particular name, which means that if the name ⌜shift-select-mode⌝ can be bound to t in the global/default environment, to nil in a buffer-local environment, and to 'bar in a closure's environment, then those are necessarily three different environments. If there weren't, then there couldn't simultaneously be three bindings for the same name.

Even if you have only global scope and dynamic extent, not lexical scope and closures, every «let» still creates a new environment at runtime that nests both in the global environment and in every earlier «let» being evaluated, and each variable bound in an environment shadows every variable with the same name in every outer environment. Even if this is implemented by storing the current environment in place of outer ones and pushing the latter onto a stack, the effect is the same.

I think you're using ‟environment” to mean something different than I am. Maybe I'm using it wrong.

It has a relationship to the global variable that a buffer-local variable also has: it shadows it.

> Again, the buffer does not provide scoping.

IIUC, you mean that lexically, a buffer-local variable is defined in the global scope. But my point is that its runtime instances aren't in the global environment; they're in buffers' environments. If there were only one environment, then there could be only one instance of the variable, meaning different buffers couldn't have different values for it.

If I do (setq-default shift-select-mode nil), and in three buffers I do
(setq-local shift-select-mode (random)), how many runtime variables do I have? Do you say I have only one or two? If so, which environment(s) is it bound in?

I say I have four, each in a separate environment.

Of course, this misleadingness is a matter of perception. The names are certainly misleading to me, despite your explanation. I thought everybody would perceive them as misleading, but obviously I was wrong about that, since you don't. At least Stephen and Eli only said the names are too old to change, not that they're not misleading.

If I'm just part of a minority that fails to understand that ⌜default⌝ is the most sensible term for the Emacs environment whose variables don't shadow variables in any other environment, then of course the term shouldn't be changed.

But if I'm part of a majority that fails to understand, then resistance is futile. You will be assimilated.

Of course, those terms are not accurate at all now. But they used to be. That's why I said they're archaic.

Probably you mean the same thing I do, just phrased the opposite.

But given the feature, the name isn't archaic. If I had to choose a name today for that function, ⌜fboundp⌝ would be a fine choice. That's all I meant.

   If I'm just part of a minority that fails to understand that
   ⌜default⌝ is the most sensible term for the Emacs environment
   whose variables don't shadow variables in any other
   environment, then of course the term shouldn't be changed.

   But if I'm part of a majority that fails to understand, then
   resistance is futile. You will be assimilated.

This particular line of thinking has led to "hacker" being a
denigration in society at large, among other more serious
atrocities.

I think if you program in C, it is easy to see how ‘switch’
.. ‘default:’ illustrates the dynamic aspect of the concept.
Rather than "this thing does not shadow", i see "this action is
the last recourse".
