Rename `eww' to `web'

Rename `eww' to `web'

[Richard Stallman]

One way we can make Emacs more usable is by giving commands
natural names that make no demand on users' memory.

Since `eww' has never been in a release, let's rename it `web'
now, before users get it.

We could add an alias.  The advantage of a "real" name is to simplify
search ("emacs eww rendering problem" vs "emacs web rendering problem").

It's a question of the user interface.
An alias is an ok method, if that is really better overall.

Same as for "epa-*", this is a general problem of how to map general
functionality to the name of the particular package offering it.

So far we've mostly used the menu bar or M-x apropos for that.

But maybe we should try and develop something better specifically
for that.  E.g. M-x aliases with intuitive names which then let you
choose which package to use for that feature.

Agreed.  It's a better approach than `(defalias 'irc 'rcirc)'.

All for it.  There are many hard-to-search examples, for example:

* C, D, Basic, Go (programming languages)
* X (windowing system)

It can often be difficult to search related stuff about them.  If Emacs
is called "Edit" or "Editor", I'll be annoyed, too.

Why refuse the right of someone to name a package his own
quirky/creative way.  Quirky names are easy to remember.

eww is not a lisp library but a functional package.

Alas, it is not so.  Quirky names are easy to forget, especially when
there are lots of them and you only rarely think about them.  Especially
if you're getting old.

Moreover, users who have never have seen the quirky name have no
chance of guessing it.

The fact that this is not only for Lisp programmers makes the issue
more important.

Emacs has lots of key bindings, and people remember only the ones they
use often.  The command name is supposed to be easier to remember than
the key binding.  It is impossible to find natural key bindings for
all the commands of Emacs, but we can give them all natural command
names.

Web browsing may be important enough to justify a toolbar icon.
But the command name should be natural too.  Ideally a command
should have the name you would guess it has (if you didn't know).

If the goal is to improve usability, forget command names.

The user wants to open a URL.  Make a menubar entry File->Open URL.
That will take care of most new users' needs.  Maybe give it a toolbar
icon, but that's IMHO much less useful.

Then make `C-x C-f' open a web browser (through `browse-url' or
whatever) by default.  Right now there are ways to open the contents of
the URL as a file, which will be disabled by this change, but IMHO
that's the way to improve usability.

Alternatively, reserve `C-x C-u' or something like that for web browsing
specifically.  But I really think piggybacking on the familiar `C-x C-f'
sequence is the right way.

Er, what?  This is Emacs.  M-x is important, and lots of people use it.

This is especially true for something like this browser, which I
expect people will only use occasionally (most people will have a
standard web browser available most of the time)

A defalias is trivial and works well anyway, so there's no reason
_not_ to have it...

There are different ways to use Emacs or indeed any bundle of methods
and information.  You can zoom in on a specific thing, which `M-x
command' does, or you can explore a visual hierarchy, like the menus or
a tree of packages and options, or you can search (with partial command
completion or the manual's index or other means).

But all of the above imply there's a tool intervening between you and
the URL, and you're trying to discover the tool's name (the command name
in Emacs).  Most users just want to enter a URL and browse it.  So my
main suggestion is to make `C-x C-f' on a URL open a web browser like
`eww', or call `browse-url', or do something like that.

I didn't imply otherwise :)  I just don't think `defalias' will enhance
usability.

Yes, something like it should be the default, if it can call `eww' when
libxml is available and just get the URL contents otherwise.

This is all fine, but seems to totally miss RMS' point. We can debate
default settings, type handlers etc as much as we like, but I think
Richard's point was that since we are introducing a new feature, lets make
it easier for the user by calling it someting obvious rather than the more
cryptic. Using 'eww' may be considered 'cute', but it certainly isn't
'natural'. You will have to put in real memory effort to remember that
emacs' in built support for web browsing is 'eww'. Sure, with the great
searching mechanisms of emacs, most users will be able to find this
procedure fairly easily, but surely it is better if they don't even have to
look or use any effort. This is especially relevant for a feature like this
which is unlikely to be used by a lot of people every day.

Years ago, I had a real problem remembering M-x ielm. Because I only used
this command occasionally, I was never able to remember it. Even with
apropos et al. it often took longer than necessary to get the right memory
jog. Using names which are as 'natural' and reflect purpose as much as
possible will help and certainly won't make things worse.

+1.  There is really little excuse for such names as Emacs commands.
A command name should preferably be something that `apropos' can
help with.  In general it should have components that are
recognizable keywords.

I think the package author should decide this.  The "natural" name you
suggest is bland and generic.  Do you really want to use a text editor
named "text-editor" and a web browser named "web-browser"?

eww is just as good as Chrome or Firefox/Netscape/Mozilla or Lynx or...

Or, in Emacs land, let's take helm, or gnus, or eieio, or...

OTOH as Stefan suggested, there is a case for generic commands to do a

Especially when there are several of them. This particular `new

Unencoded full URL's cannot be valid filenames under the vast
majority of filesystems, including GNU/Linux and macosx. I think
they might theoretically be valid in w32 systems like ntfs, but
many (most?) of those systems already allow the user to enter URLs
where filenames are requested, so it doesn't seem likely to be a
problem there, either.  Anyone know for sure?

It seems like we just recently built this dispatcher functionality
for sending email from emacs, didn't we?  If not, perhaps it's as
simple as a set of standardized aliases for common functionality,
with the defaults set to a choose-from-a-list function?

@tzz: That's hardly likely to make the user happy.  f-f-l delivers the
bytes found on disk, completely uninterpreted.

"Valid *canonical* filenames".  In most cases the "//" marking the
authority will be interpreted as a single path separator.

I don't think so; the "//" prefix for a share can't be preceded by a
drive letter.

Where's the system issue?  Inside Emacs, URL-encode whatever you're
given and prefix "file:///" to it.  If that exists, ask the user if
the local file is what they want.  Otherwise, try the URL-encoded form
literally.  This try-and-prompt behavior should be optional, as I
suspect it's rarely applicable and even more rarely wanted.

The issue here is going to be edge cases involving `default-directory',
which should probably be renamed `default-base-url'.

No, that's been around for decade, at least.

It's not that simple.  The base case is, but users typically want to
be able to tune their preferred implementation.  For common options,
there should be standard custom variables in Emacs, but people should
also be able to drill down to the implementation and use its option
names.  Building a generic way to handle all this functionality for
different applications is not going to be trivial.

For the moment I think building dispatchers on a case-by-case basis
isn't so hard, and eventually somebody will get the itch.

I would only accept absolute URLs.  Relative URLs should be handled by

http://gnu.org/index.html is a valid file name.  In Emacs, it is

No one suggested that.  What "natural" name did you think I suggested?

> eww is just as good as Chrome or Firefox/Netscape/Mozilla or Lynx or...

Richard responded adequately to that claim.  Of course, with enough
recognition any name becomes recognizable! ;-)  "EMACS", for instance.

> Or, in Emacs land, let's take helm, or gnus, or eieio, or...

Have you been following?  Those are package names, not command names.

 EIEIO: a package
 `eieio-browse': a command

 Icicles: a package
 `icicle-complete-keys': a command

Again, `apropos' can help a user find a well named command, one
whose name suggests something about what it does.

But by all means, the package name can well be something that stands
out, in particular for a web search.  That can help, once there is
some general recognition.

On the other hand, "Emacs" already stands out in a search for web
browsers.  If you were looking for an Emacs web browser today (and
there are some), I'd be willing to bet that you would search for
"emacs web browser" or some such.  Why so prosaic and unimaginative?
Because that's what works.

Let's just have a configuration module that let map user interface
commands to the selected package.

M-x mail --> vm, gnus, mew, or whatever.
M-x news --> gnus or something else.
M-x web --> w3m, www, eww or whatever.
M-x elisp -> ielm or *scratch*

It's not the same kind of interaction.  ielm simulates an "interactive"
REPL, like other lisps or shells.  Even slime has both kinds of
interactions available, the *scratch* like, and the repl one.

Also, compare the results:

(+ 1 2) C-u C-x C-e (+ 3 4) C-u C-x C-e (or perhaps with C-j) in *scratch* displays:

Re: Rename `eww' to `web'

[Mathias Dahl]

[-- Attachment #1: Type: text/plain, Size: 1090 bytes --]

Hi all,

It's interesting to see how much one can discuss around a name... ;)

When my `tumme' (now `image-dired') package was added to Emacs many moons
ago, the question about its name came up. Since I was the author and the
one who had picked the name ("tumme" means thumb, in Swedish, so it was a
good name for a package aimed at working with image thumbnails), and it
also had been used by people for a while, I felt... something (a small
disturbance in the force, maybe)... when the name change came up.

However, the arguments back then was about the same as now; it is
beneficial if users can find commands by guessing and it was reasonable to
assume that someone might try typing "image" to see what nice commands
there might exist for working with images. Also, since I was glad/proud
that someone asked if this could be included in Emacs, my favorite piece of
software, it was a small thing to change the name. And, I see now, the name
"tumme" is still there in the form of an alias for one of the commands in
the package.

So you explicitly chose a name that had a meaning related to what
the package and its commands are for.

Understandable.

Which was the same principle you applied, using "thumb" instead of
"image".  It's just that your version of "thumb" was a Swedish one.

Yes, "image" is good, as is "thumb".  Depends what to put the emphasis
on, since `image-dired' can do more than show thumbnail images.  But
either is helpful, IMO.  And "tumme" is less helpful than either,
unless one understands Swedish.

> ... So, that was my little insignificant story...

Not so insignificant - a couple of lessons there, I think.

Retaining "tumme" as a command is a good and smart gesture on the part
of whoever took that decision.  

I am happy that aliasing route has gained lots of traction and that some
traces of "eww" will remain.  Who knows the non-sensical sounding "eww"
could have some meaning in Norsk (or whatever)

> So, that was my little insignificant story...

What if tumme had been erased altogether? Would you be here to tell the
story?

ps: Question in last para is rhetorical, btw.

"(#o3, #x3, ?\C-c)" should not be inserted to the *scratch* buffer
unless it is prefixed by `C-u'.  This should be fixed by the patch in
bug#12985 that will insert "(#o3, #x3, ?\C-c)" only to the ielm buffer,
and not to the *scratch* buffer.

Thanks, but I still can't see it (with or without prefix argument, in
*scratch* or in *ielm*).  I'm using r113216 (trunk in 2013-6-29).

I just see:

There is an obscure feature that typing `C-x C-e' twice displays
full information in the echo area, and typing `C-u C-x C-e' twice
inserts full information to the *scratch* buffer.

bug#12985 proposes to fix this (mis-)feature to insert full information
to the *scratch* buffer only when you type the C-u arg, i.e. `C-u C-x C-e',
and always display full information in the each area and in ielm.

Ah, I see, thank you!  I saw it with two successive `C-u C-x C-e's just
now.

I'd use "define-" rather than "def" (and I'd keep "dispatcher-" as the
prefix).

Looks good (tho obviously, we still need to actually use it to define
entry points).

Defining entry points is as easy as

;;;###autoload
(define-dispatcher browse)

etc. Where would they go? In dispatcher.el?

As for pushing values to dispatcher-*-alternatives, that's something
for the different packages to do.

Well, if we install this code, someone else can add these

As for this dispatcher-define, two questions:

- If so, in its own dispatcher.el, or as part of an existing package?

For now we can keep it in simple.el, I guess, since it's very small.

`dispatcher' is a too technical term.  A more user-friendly term would be
`alternatives' like you can see on GNU/Linux in /etc/alternatives/ that
can be customized with such commands:

  update-alternatives --config x-www-browser
  update-alternatives --config gnome-www-browser

Using similar names like `alternatives-define' and more specific
`www-browser-alternatives' or `browse-web-alternatives'
would be more familiar to the users of GNU/Linux.

IOW, you took the subject of http://lists.gnu.org/archive/html/emacs-devel/2013-06/msg01427.html
too literally.  There is no word "dispatcher" anywhere in command and variables
proposed by Stefan in this message.

IIUC, you're proposing that the macro be called "alternatives-define".

I don't understand in which context would "www-browser-alternatives"
or "browse-web-alternatives" be used. For which commands are these
options? www-browser and/or browse-web?

I'm low on bikesheding. I choose one name knowing full well someone
would complain. I don't have any preference. Your proposal suits me as
well as any other. Now, if someone else has a different proposal,
let's hear it, please.

I don't know whether `alternatives-define' or `define-alternatives',
but something without "dispatch" in its name.

If the command name is `browse-web' then the user option
`browse-web-alternatives' could define alternatives for this command.

This is like what the command `browse-url' already provides
where you can customize `browse-url-browser-function'.

But it seems that there is a need for two separate commands
`browse-url' and `browse-web' where `browse-url' is used to visit
a link from the buffer in a preferably external browser,
and `browse-web' to start browsing the Web in a native Emacs browser.

If it is in its own package alternatives.el, then alternatives-define.
If we add this as a new command in some other package,
define-alternatives is fine.

Currently, it would be dispatcher-browse-web-alternatives.
browse-web-alternatives is OK, though we lose the common prefix.

That's something to decide afterwards. I don't really care which
generic commands we define or how many do we need.

`define-alternatives' or `define-dispatch' might be better than
`alternatives-define', because some tools will recognize the former
two as definitions of the name that is the first argument.

Maybe something like

(defcustom browse-web-function 'eww
  "Function to start WWW browsing."
  :type '(choice
	  (function-item :tag "eww" :value eww)
          ...))

(defun browse-web (url)
  (interactive "sEnter URL or keywords: ")
  (funcall browse-web-function url))

Then external packages could register themselves by adding more alternatives
to this user option by calling at the end of e.g. the w3m package:

  (custom-add-option 'browse-web-function '(function-item :tag "w3m" :value w3m))

Indeed, for browse-url, there's already something in place.  I'm suggesting it could be generalized, by defining generic user interface commands for several applications.

Evaluation with C-j does not display the character equivalent

Yes, and the order in which the different parts are inserted, when using
C-p C-e or M-p:

     M-x ielm RET (defvar *i*) RET (setq *i* 0) RET (list (+ 1 2) (setq

It seems likely that those who go looking for an Emacs Lisp REPL might try
M-x repl -- perhaps a defalias is in order.

I don't think that mnemonic will help me remember, the next time I see

and I will have had plenty of chance to forget.

    But all of the above imply there's a tool intervening between you and
    the URL, and you're trying to discover the tool's name (the command name
    in Emacs).

That's a very common kind of case in Emacs.

		Most users just want to enter a URL and browse it.  So my
    main suggestion is to make `C-x C-f' on a URL open a web browser like
    `eww', or call `browse-url', or do something like that.

This would be a convenient interface.  We just have to solve the
problem of ambiguity: a file name can look like a URL.  We could make
some way to indicate it is a file name -- perhaps some way to quote
the colon that would follow the URL type.

I think it's pretty easy to tell a URL (we already do that in many
packages), and the user can always use `find-file-literally'.  So I
think this is not going to be a problem and doesn't require any special
treatment.  Just in case we could check if there is a file named the
same as the URL, since a stat call is cheap.  But otherwise this should
be DWIM for the users.

find-file-literally has nothing to do with the interpretation of the

This is off-topic, sorry.  I'm using a wrapper[1] that modifies
`C-x C-f' and `C-x d' so as to work for ftp://.  I can imagine
making those commands work for https?:// is not so troublesome.
Note that a url containing non-ASCII characters needs to be encoded
properly.

Really?  I thought org-mode was the mode-to-end-all-modes? ;-)

No, it's not.  find-file is a prelude to *editing*, so you should
receive the "preferred form for editing".  One could argue that Emacs
should try WebDAV to get its insdels on the source of dynamic pages,
but that seems unlikely to work without substantial configuration,
perhaps on a file-by-file basis.

The interface you are looking for is M-x view-file in my installation
(Emacs may have that bound to key by default).

Of course that's not quite right because the name says "file", but the
same applies to C-x C-f == find-file.

It is a mode that uses all other modes, but puts or gives it's own name.
That would mean either assimilation or appropriation.  I wouldn't get
there :-)

>  WebDAV

Don't forget the Wikis.  It will be awesome, if I could just 


        C-x C-f http://www.emacswiki.org/emacs/EmacsNiftyTricks
        C-x C-s

and let the URL handler - I believe it uses the same "file interface" as
TRAMP does - do the right thing in the background.

----------------------------------------------------------------

There has been some discussion surrounding saving (auto-?), killing
notes buffers.  Now the Notes buffers need not be local buffers.  It
could be a buffer that will be eventually saved via a POST to a wiki
backend.

So plugging in URL handling to a standard "interface" for file handling
could have it's benefits when it comes to autosaving, taking backups
etc.

That's arguably right.

Actually, it's the main problem: url-handler-mode only affects the way
files are accessed, but not the way we try to find/guess meta-data, so
the HTTP header's info (mostly Content-Type:) is completely ignored and
instead we rely on the URL itself via auto-mode-alist.

It would be nice to extend url-handler-mode so that the meta-info from
things the transfer protocol gets preserved and used to choose the
major mode.

This is yet another needed change, which is to make it show a rendering,
just like opening a PDF file gives us the rendering (via doc-view)
by default.

I would rather just open URLs the same way consistently with `eww' than
try to guess what treatment each one merits.  `eww' or other web
browsers should DTRT once they get the content and the headers.

Opening a HTML *file* should open it as a file, and rendering should be
easily accessible in a menu (through `shr' or whatever).  A PDF is not
the same use case, because viewing and editing a binary PDF as a file is
pretty useless.

Opening a URL may produce HTML or something else, but there's no editing
model here--you can't write back a URL (yeah, there's PUT, and for file:
URLs you can open the actual file, but let's stick to the common case).

So I think it makes sense to go straight to `eww' for that case: opening
a URL with `C-x C-f'.  Like I said, it's DWIMmery.  There will be a
small percentage of users unhappy with it, who will want to just view
the file, and we should make that easy (I guessed `find-file-literally'
incorrectly but it can be something simple to set in `url-handler-mode'
defcustoms).  The key thing is that there are no command names to
discover--opening a URL Just Works.

Any of the developers can make the change easily but it's a pretty major
change and that's why we're discussing it instead of just doing it.  I
hope you agree with me.

I currently use C-x C-f with url-handler-mode on a regular basis to open
PDF, tarballs, and Elisp files.  Sometime it gets it wrong because it
only uses the URL name rather than the content-type metadata to choose
the major mode, but want to make sure this keeps working.

But I don't see any reason why this should collide with using eww in
other cases: eww can't do anything particularly useful with PDF,
tarballs and Elisp code anyway.

Why would you want to use eww for all URLs, since it only handles HTML
in a useful way, AFAIU?

Fine by me (BTW, I've been using the hack below to ape completion
on http URLs).

So `eww' should pass data to the registered handler for that
MIME type, like most web browsers?  I think that's sensible and would
simply shift the dispatch responsibility.

OK.  IOW, `eww' and web browsers in general are supposed to be
navigators between content, while the content itself is rendered by
either a HTML/CSS/etc display engine (`eww' uses `shr') or passed off to
an external handler.  So I think this is a manageable problem, if we
simply say Emacs is the fallback handler for any content `eww' doesn't
handle, and provide a way in `eww' to pass the content off to Emacs.

`eww' browses the URL, then decides how it should be rendered or
downloaded.  You don't know the type of the URL until you retrieve it,
so a generic dispatcher/navigator like `eww' is your best bet.

I don't care too much about the dispatcher, though, so it's OK with me
if Emacs is the default dispatcher (the current status) and we make it
easy to make `eww' the default instead.  Perhaps with Juanma's
dispatcher.el.

Nice.  I'm not sure if it should be a package or a built-in feature, but

Maybe it's fine to let eww handle the mime-type -> major-mode mapping.
But it's still unclear how to cleanly cause url-handler-mode to affect
C-x C-f such that eww is called.

I believe, the actual gluing could be achieved with minimal investments.

The magic seems to happen so.

   (get operation 'url-file-handlers)
   (put 'insert-file-contents 'url-file-handlers 'url-insert-file-contents)


So `url-file-handlers' (actually `url-insert') need to check for
`(mm-handle-media-type handle)' and call one of the handlers (See
`eww-render').

	  (cond
	   ((equal (car content-type) "text/html")
	    (eww-display-html charset url))
	   ((string-match "^image/" (car content-type))
	    (eww-display-image))
	   (t
	    (eww-display-raw charset)))


Are there any intervening operation between `insert-file-contents' and
`find-file-hook'.

   (add-hook 'find-file-hook 'url-handlers-set-buffer-mode)

----------------------------------------------------------------

Is `find-file-hook' the right place for a `renderer'? For "multipart"
buffers are there renderers on a per-part/region basis.  

----------------------------------------------------------------

Btw, url-handler-mode seems to be doing synchronous fetch while eww
seems to do an aynch fetch.  Should C-x C-f be "blocking" or can it be
an "asynchronous" C-x C-f?

----------------------------------------------------------------

As for write operation, "Wiki URLs" are "writable" and can also be
"renamed".

The answer seems to be `format-decode'r.

How about...

1. Pass the Content Type from HTTP headers to `buffer-file-format'

2. Augment `format-alist' with "text/html" format and make `eww' (or
   shr or whatever) a decoder for it.

The advantage would be that HTML rendering is isolated from URL
retrieval operations.

The problem is indeed that find-file's code separates the "fetch data"
from "setup major mode", so the way it works is fairly different from
the way eww works.

That doesn't sound very reliable.

Indeed, that's another important difference.  Maybe if we want to invoke
eww from C-x C-f we need to do it at a higher level than in
insert-file-contents and/or find-file-hook, e.g. something more like
find-directory-functions (tho not for directories), and only if
find-file is called interactively.

Strange.  I see the same "Unimplemented" error on r113216

I've now bisected my init file.  The "Unimplemented" error is due to
enabling read-file-name-completion-ignore-case.  I've filed a bug report
(bug#14806).

Maybe fixing this will also fix bug#11339 (file name completion
involving non-ascii characters with
read-file-name-completion-ignore-case).  I've been hoping a long time
for that to be fixed.

Yup.  The necessary changes to make this usable IMHO are:

I'm trying to get agreement on these two.

I think that it's nice that things have names that enables users to
search for help for that thing.  Searching for "web" isn't very helpful.

But the idea of having a command called `web' that would call (for
instance) eww sounds good to me.  But I think we have to keep in mind
that there are typically two distinct things that people want when they
say "Emacs, here's an URL".  The vastly most common thing to want is to
start an external web browser like Firefox.  But some people want to use
an Emacs-based browser for specific things, so I'm not sure having a
command like `web' would be of much convenience in practice.

There's also the issue of "what does the user expect to happen when they
tap a link in eww?"  I think the natural thing to happen is to open tat
link in eww -- i.e., continue to browse in the browser you're using.
But sometimes you want to browse using an external browser, even from
eww, which is why eww offers that as a separate command.

So, in short: I don't think eww should be renamed web, and I think
having a command named `web' at all won't be of much use, even as an
alias/dispatcher.

Making things easy for users must take priority.  We cannot regard a
name as somehow "occupied" by code that we don't somehow distribute or
recommend.

Even if we did somehow distribute or recommend that code, we might
still want to use that name for something else.  Making Emacs

I agree with this.

But there is also the question of encouraging users (like me) to
contribute to the large available code.

If you consider Emacs to be successful just because of the code included
in the distribution that would seem to me to be a rather restricted of
things.

Simple alternative entry commands for an Emacs browser are easy to come
up with:

browse-web

open-web

even web-open would not interfere with my package.


Having said that I agree that the word "web" is important and probably
should be reserved in some way by Emacs.

I'd be more than happy to contribute my web library to Emacs. In summary
it is a simpler programming API of what the current url offers as an
HTTP library which offering more complex functionality (like streaming).

I think this approach is offensive to the community. The Emacs ecosystem

reason to take over the name of an established package.

Making third-party developers unhappy is not a very good way to make
users happy.

That said, I don't feel that `web' is a particularly good name for a
browser package. It's too generic and bland - if I was looking for such
package, I probably would search for `browser' or `internet', not `web'.

And making `browse-url' default to `eww-browse-url' doesn't require
changing the name of the latter.

Would you take a name of an existing, live project for a new GNU project 
with similar functionality, even if it were a good-sounding name and it 
were convenient to do so?

I don't believe Emacs packages are any different in any relevant respects.

Thanks for your contributions, but they don't entitle you to make demands
of this sort.

The issue is about command names, so you've changed the subject.

If we're talking about package names, then we want to avoid confusing
users.  Therefore, when we give a package the same name as some other,
we normally add "GNU" to distinguish.

For instance, I wrote a program called Emacs even though there were
other programs called "Emacs" at the time, and we made a Tar program
even though there were other programs called "tar" at the time.  To
avoid confusion, we refer to them as "GNU Emacs" and "GNU tar".

However, the issue at hand is about command names.  We use the same
command names used by various other packages whenever that seems
convenient.  For instance, the command to run GNU Emacs is just
`emacs' and the command to run GNU tar is just `tar'.

I do not recall making any demands. If you mean "you better" (should've

You've got a point there, but with Emacs' lack of modularity command 
names usually unambiguously map to package names. Some commands in the 
Emacs core being the exceptions.

I don't know the history very well, but it seems to me that either the 
programs you replaced were incompatible with systems you were targeting 
(so you did, essentially, port them), or you didn't care about pissing 
their authors off, for example because the original programs were 
proprietary software. Or both.

Neither is likely to be the case with third-party Emacs Lisp packages.

I think this approach is based on the assumption that no user would want 
to have both programs installed on their system at the same time.

Re: Rename `eww' to `web'

[chad]

There's a lot of debate about respecting developers, making things
easier for users, and preserving the fun of quirky names here, but
it seems to me that most of it might be missing the goal in favor
of arguing about potential details (and potential details of
potentially related but different topics).

Richard's goal (as I understand it) is making sure that users can
find important features in Emacs, not to enshrine or take over any
particular piece of code. For browsing the web inside emacs, there
are at least 4 packages: emacs-w3, emacs-w3m, emacs-web, and now/soon
Lars' new eww. These are all more and less hidden from straightforward
user behavior like `look through the menus', `try obvious command
names' and `internet search engine'.

I think most of us agree that emacs should have an easily-guessable
and -remembered command name for this functionality, and that `M-x
eww' might not  be it. This doesn't mean that we need to rename any
of the four packages above, but rather that we need to provide an
intuitive entry point. Emacs itself already provides such an entry
point, in browse-url.

We should make sure that browse-url works with eww - this is already
being done.

We might also want to discuss whether or not `M-x browse-url' is
itself the best choice of name for an intuitive entry point.

We should add a menu-bar entry for whatever name we decide to use
for browse-url above.

I hope this helps,
~Chad

Well, we can do many things that can make (most) users easy.  For
example:

* Turn on cua-mode by default
* Add a "redo" command
* Change the terminology of “kill” to “cut”, and “yank” to “paste”
* Switch the terminology of “window” and “frame”
* Change the terminology of “car” to “first”, and “cdr” to “rest”
...

But we can't, since many of them will break existing users'
configuration.  Although eww doesn't have this problem, I think we
should think twice before "making things easy for users".

This user would hate that.

Might be nice.

But kill is strictly not the same as cut, and yank is not the same as paste.

Should reduce some confusion.

Not sure many users care.  Most users don't program lisp.

Also, what is easy for one user is a pain for another.  Not all you suggestions are even obviously easier for a user.

Or, as Bob suggested, change "kill" to "clip".  See (info "(eintr)
Cutting & Storing Text").  BTW what's  the difference of kill and cut
(and yank/paste)?

I agree.  I just picked some random examples in my mind, and haven't
done any research.

So I said "most" (just in my opinion) users.  Maybe we should do some
social researches (polls) or systematic analysis, like this
survey[fn:1].  If we can't, picking something in etc/TODO and implement
it is better than span this thread into hundreds of messages and
debates.  (And in the end, typically nothing is done or changed.)

Kill in Emacs saves to the kill ring, there is no cut ring that applications share.
Corresponding for yank.

It would be perfectly "fair."  If you use a highly generic name for a
package, you shouldn't be surprised when somebody else uses the same
name, and there's little justification for feeling wronged by it.

For that reason, it's obviously a bad idea to choose highly generic
names for packages...

[See the whole stupid mess with "*Step" and their apps called
"Terminal", etc... ><  Sure that made sense in a highly controlled
closed ecosystem; it makes zero sense in a shared open ecosystem.]

*However*, such names are desirable for the user when they want to just
start the app.

So the most practical thing to do seems to be use non-generic names for
packages and specific apps ("eww"), and generic names for shared thin
invocation layers [e.g. the simple (defalias 'web 'eww) dicussed
before].

This is a serious issue of usability.

There is nothing particularly wrong with "ewe" in a command name,
but it's not a very natural name for a command to browse the web.
Few users, when straining to remember or trying to guess the way
to browse the web in Emacs, will hit on M-x ewe.  If it is
M-x web, they will find it easy to remember and to guess.

We already have M-x browse-url.  If eww is a suitable replacement for
that feature perhaps we should make M-x browse-url run eww.

Or maybe both.

Not really.  I doubt they ask the AIs to swear loyalty to the Constitution.

M-x emacs-web-explorer

(defalias 'ewe 'emacs-web-explorer) ; Pseudonyme pour Mlle Gnu.[*]


[*] Yes, it seems the more correct term for a female gnu is "cow",
not "ewe" or "doe".

Neither of these names is very helpful to a user who is
trying to figure out what to type after M-x to do some browsing.

Many people think "browser" when they see "explorer" (and vice
versa), just as they did at one time when they saw "navigator".
But yes, it's no doubt true that "browser" is the more generally
recognized term now.

It seems that Mozilla Firefox and Google Chrome, at least, do not
refer to themselves as "browser" or anything else, beyond their
names.  Clearly they didn't worry too much about finding a name
that suggests "browsing" to potential users.

Perhaps they expect users to run them via icons or menus
and not with M-x.

Also, those programs are extremely well known, and the people who
use them use them daily.  So people don't have a problem of wanting
to use them and not recalling their names.

It is otherwise with lots of facilities in Emacs.
