a dark theme?

a dark theme?

[Sharon Kimble]

[-- Attachment #1: Type: text/plain, Size: 689 bytes --]


I'm hoping that someone can advise me, I'm looking for a theme to use
with emacs and gnus which has a dark background, but also allows me to
read all the text in a gmail which currently appears as nearly-white on
a slightly-grey background.

I've recently been using  aalto-dark, aalto-light, adwaita, alect-black-alt,
tsdh-dark and all have failed the gmail test. I'm currently using tango,
which is the complete reverse of what I'm looking for.

Can anyone help please?

Thanks
Sharon.

I like solarized-dark, or tty-dark.

I just said I don't like themes, but tty-dark - come to
think of it, maybe that is good!

I don't think that has anything to do with themes, but SHR which renders
HTML mail in Gnus just picks bad colors to confirm with what's declared
in the HTML text.  But you can force it to require more contrast like
so:

  (setq shr-color-visible-distance-min 10
        shr-color-visible-luminance-min 60)

With that, I'm pretty satisfied with the results.  (I'm the author of
the tsdh-{light,dark} themes and switch between dark and light every
half a year.)

Brilliant, thank you very much, that little code snippet has completely
sorted the problem out! I can now read my emails in my gmail inbox with
no problems at all, thanks.

Can you provide some code so I (and all of us) can see
what it takes to formally qualify as a "theme" - I
don't think many people share my taste but some might,
besides it would be interesting to do. Is it just faces
that are included in a "theme" or is it other configs
and extensions as well?

With a recent enough Emacs version you can look at them yourself - Emacs
24.3 ships with 13 themes out the box: /usr/share/emacs/24.3/etc/themes

Custom themes use the `deftheme'-macro to create themes and are, as you
stated, "just a list of faces".  Have a whack at M-x
`customize-create-theme'.

It's a bad trip but I'll take it.

Ha! The adwaita-theme only has 70 lines of face
settings. I have 94 and I didn't even know the concept
of theme until now... But when I load-file my faces
from the state of a previous built-in theme, there are
remnants of the old order so my "theme" is nonetheless
incomplete, it seems.

OK. There was a guy on this list - Jambunathan K - who
was in contact with another guy who did Emacs "suites"
with skeletons of Emacs configuration to appeal
to/offer a head start to certain personalities and
expected usage (as in bright-on-black, programming,
Gnus, and so on) - I don't know what happened to them
and that project, or if they even included faces, but
they should as Gnus for example is dead boring without
some makeup.

I just grepped the sources.  Emacs has 803 faces only in its core and
built-in packages.  So a really complete theme might require some work.

(But it's a common and good practice to derive all faces for a package
from the standard emacs-core font-lock faces, so changing those will
also change the appearance of the derived ones.)

Yeah, completeness for completeness sake is silly
anyway. But perhaps when you invoke a theme it could
call a defun that would "reset" Emacs to an
unconfigured state, in terms of faces, otherwise the
result of applying the theme is unpredictable with
respect to... at least details, in the "face" of
previous configs and themes applied.

Come to think of it, I always said themes weren't
creative but perhaps I underestimate people, this
"incompleteness feature" of themes makes it possible to
combine them...

You mean like this?

(defgroup fpscalc nil
  "The `fpscalc' mode."
  :group 'local)

(defgroup fpscalc-faces nil
  "The faces used by the `fpscalc' major mode."
  :group 'fpscalc
  :group 'faces)

(defface fpscalc-program-parts
  '((t :inherit font-lock-keyword-face :foreground "magenta" :bold t))
  "The words declarations, initialise, semaphores, and formulas."
  )

"All the text in a gmail"?

To get a default bright-on-dark "theme" (which I highly
recommend to reduce eye strain) simply evaluate this:

(set-face-attribute 'default nil
                    :foreground "cyan"
                    :background "black"
                    :bold nil)

Change "cyan" to whatever fits you the best. I use a
Linux VT/tty/"the console" and you probably use X. That
means I can't help you with the colors, but try
"green", "blue", etc. See if you can find something you
like; if not, dig deeper. Probably you don't won't bold
for ordinary text, save that option for faces that
highlight stuff (headers, keywords, and so on).

If you run into some text that you don't like the color
of, use this defun to identify the face:

(defun what-face (pos)
  (interactive "d")
  (let ((face (or (get-char-property (point) 'read-face-name)
                  (get-char-property (point) 'face))))
    (if face (message " Face: %s" face)
      (message " No face at %d." pos) )))

Put it in an init file, for example ~/.emacs. Then
invoke it with `M-x what-face' with point at the face
you don't like the color of. This will show you what
face it is. Then do as above again, only substitute
'default for the face you found. Note that several
modes/modules of Emacs uses the same faces. So if it
looks great with brown somewhere, it might not look as
great somewhere else, and of course, if you change it
again, the first place may look less good! In practice,
this is seldom or never a problem. If it is, it is
solvable but I never got to that. Just go for what
sticks out in a pleasant way, it should work
everywhere. Where applicable, put some thought into it:
with programming, the `font-lock-comment-face'
shouldn't be as bright and emphasized as
`font-lock-function-name-face' (because people
comment-out stuff, and read comments only as a
secondary measure, when they don't immediately
understand the code), what's more, perhaps red is a
natural color for `font-lock-warning-face', and so
on. But don't overthink it. Most important thing is it
should look clear, relaxed, and fun. Check out this
screenshot of a modest major-mode a once did. That's
how I like it. Obviously I didn't intellectualize every
singly color I put to use. It is still very pleasant to
work in such a mode - like a night club :) [1]

The problem with themes, which I didn't know existed
until this discussion by the way, is that you find one
mode, you like it to 80%, but not quite, so you look
for another, maybe you like that to 90%, and so
on. Instead of jumping between Emacs themes, Linux
distros, and so on, just put that time setting it up
the way you want it. Plain and simple. Time-consuming,
yes, but educational. Fun. And ultimately, much more
capable of getting not to 90% but (almost) all the way
(and those last percent missing not because some
perfect theme is eluding you, but because of your
current understanding and skills. Remember,
"Don't chase the dragon - become the dragon!"

Thanks for this Emanuel, I've doctored my init.el and put the above in
it, at the end, which is where I always put temporary/testing code,
unless it goes into my setup-testing.el. I then ran it when my mouse was
on the problem text in a gmail, and this is what it found -
╭────
│Face: ((:foreground #5e5e5e) (:foreground #5e5e5e) (:background #727272))
╰────

Perhaps I'm misunderstanding you, but how can I customise that? Its got
no name or handle that I can hook on to!

This looks like rather hard work!

If you move the cursor to the text whose face you would like to customize
and do M-x customize-face, the emacs offers you the face at point to be
customized eg.

Customize face (default `gnus-cite-2'):

Just hit return  and you will be taken into the Customize menu for that
face.  Or  use that face name for the magic you want to work in init.el

Emacs 24.3.1 here on Linux

An idiot can set the faces in Elisp (I think).

Baby steps first. And this is an especially good baby
step, because it gives instant feedback and is ideal
for experimentation and trying out new stuff: how the
editor responds to the edits and the evaluation...

This is hardly "rather hard work", it is pleasant,
interesting, low-intense work:

(set-face-attribute 'default nil
                    :foreground "cyan"
                    :background "black"
                    :bold nil)

But of course `customize-face' is there for anyone to
use, I already told my prefered way (and now twice) so
it is all fair this method also gets mentioned... Emacs
is not a religion (right?).

No, you can't customize a face unless you know its
name...  - and I have never seen such output from that
function. You mention the mouse, instead try just
placing point (the cursor) on the text and invoke the
function. Do you get a different result from that?

You still haven't told us what you mean by "gmail"?

The first is where there is text, and it gives -
╭────
│ Face: ((:foreground #737373) (:foreground #737373) (:background #5a5a5a))
╰────

and the second in the same message but in blank space, i.e. with no text.

Google mail is a lesser-known name for the service, but its mostly just
known as "gmail".

Yes.  But how are you viewing gmail?  Using an Emacs web-browser such as
EWW, W3 or W3m?  Or are you getting Gmail using an Emacs mail client
like Gnus or Rmail?  That changes what needs configuring.

If you're using a web-browser note that gmail itself has themes, so you
can change the background and text colours there.

Gnus.

But the problem has now been solved, and it works with whatever theme I
use.

Well, of course it is good that the problem is solved
but that doesn't mean you can't elaborate so we learn
even more. You use Gnus but not only to access a gmail
account (like in retrieve from a mail server) but it
also conveys a gmail interface, in which the standard
gnus- and message- faces aren't in effect? To me that
sounds backwards because to me Rmail and later Gnus
were very appreciated ways (orgasmic even) to never
have to deal with mouse- and browser-based
web-interfaces... and that's just part of it.

Yes I use Gnus, but I'm still learning about it and tweaking it to get
better performance. There is =no= "gmail interface", just downloading
From gmail servers like this in my .gnus
--8<---------------cut here---------------start------------->8---
(setq gnus-secondary-select-methods '((nnml "")
                                      (nnimap "gmail"     (nnimap-address "imap.gmail.com")))     
                                      	  gnus-select-method '(nnnil "")
--8<---------------cut here---------------end--------------->8---
and it auto-creates its own mail folders to mirror the source
gmail. Then its just treated like any other email. 

But this is the "killer-code" which makes it possible to read emails
From gmail -
--8<---------------cut here---------------start------------->8---
;; from Tassilo Horn, 17/7/14
  (setq shr-color-visible-distance-min 10

Yeah, but isn't that a contradiction in terms...? If it
is just fetched from the gmail servers and treated like
any other mail, why should you need any killer code at
all? Why isn't the ordinary gnus- and message- faces at
play? But feel free to drop this anytime as I don't use
gmail myself and even my super-human curiosity is
starting to wane...

But without that "killer-code" its almost impossible to read emails
generated in google-groups in your gmail-inbox as they have a light
background and an almost light text if you're using a theme with a black
or grey background.

I don't understand exactly what the code does or how it works, but
having it in my .gnus has made the unintelligible gmail emails
intelligible!

And that’s all I'm going to say on it :)

Ah, I was right with my guess and happy that my configs work.

By the way: in your google groups settings, you can configure that you
prefer plain text mail over HTML mail (not sure if there is a global
setting or a setting for each group; possibly both).  I'd advise that
you do that.  There is no good reason for HTML mails, especially not in
discussion mailinglists like google groups.

With that plain-text setting, you wouldn't need my configurations.  But
in any case, they don't hurt and do a good job in case you forecfully
receive HTML mail.

Tassilo

Yes, I thought HTML mails were a thing of the 90s!

But wait, this only gets more confusing... If the OP
uses Gnus to fetch mail from a gmail account,
shouldn't that mean she gets them in certain ways not
because of her gmail settings, but because of how people
sent them to her?

I mean, what happens if someone sends an HTML mail to
me? I use Gnus which fetches the mail from a mail
server, just not one of gmail's in particular. If Gnus
doesn't parse them to plain text by default somehow, I
should have seen some occasional HTML mail, one would
think. If Gnus does that, I guess we could provide that
option to the OP just as well?

Well, most HTML mails contain both the HTML as well as a plain text
representation of the contents, and then you can teach Gnus which one to
display.

And with google groups which are a kind of hybrid between mailing list

prefer to only get plain text (or HTML) mails.

OK, but that cannot be it as I have that nil. I'll look
around, tho...

OK. But, Google groups, isn't that rather a web
interface to the nntp Usenet which is distributed?

No, google groups has a set of groups that are completely separate from
the Usenet.  And it only provides access via a web interface or as
mailinglist but not nntp.

OK, so if you use those groups via the web interface or
without telling you mail client it shouldn't show mails
as HTML, you get this problem? Crystal clear.

The only mention of HTML in my Gnus configuration is:

(setq mm-text-html-renderer 'w3m)

So I guess it is possible what I see is not text, but
HTML, but run through w3m, just looks the same. But, I
tried to change to `shr', and everything (what I can
see) look the same. I don't know. But I'll examine the
variable you mention anyway.

I think the gmail bit is a red herring. These problematic emails are
html emails, which are rendering using shr. The gnus faces don't seem to
apply in this case, but shr options do.

Of course, I'm not saying you shouldn't use it, I'm
saying this must be a specific situation because the
common faces aren't in play and you need extra killer
code to make it work.

That's the problem: he received HTML mail from his gmail account, and
Gnus HTML renderer SHR chose font colors with a too low contrast
(probably because "good" colors were declared in CSS which SHR doesn't
parse AFAIK).

So it has nothing to do with gmail the service, gmail the web interface,
or an emacs browser in combination with the web interface.  It just
happened that he received HTML mail from his gmail account and thus
thought the problem might be gmail related.

I've already said that in an earlier message where I provided the
"killer-code".

Who is "he"? It is not common in the UK for males to be called "Sharon"!

Oh, no. We already know you are a girl because you use

Yes, of course I know what gmail is, are you saying you
are using it from an Emacs browser? In that case, if it
doesn't assign a face, but the face is still somehow
set (the hexadecimal RGB values you posted), I don't
know how to change that.

I know that you use Gnus, so why don't you just set it
up to get the mails from gmail, if you are happy with
that, and then set it (Gnus) up plain-and-simple and
don't have to bother with the web interface and the
Emacs browsers (?). That's the reason you'd use an
"application client" rather than just stumble to some
webpage and start clicking around...
