Provide a dark theme

[Tamriel]

With the theme 'Breeze Dark' ReText looks like this:
Instead I would like it like this:

• The colours should be the same in the editor and in the preview
• The font colour should be bright, not black
• The colour for links should be e.g. cyan, not dark blue

You can already tweak the colours as you like using the combination of colour schemes (for editor) and styleSheet (for HTML).

But I will try to make the default choice more smart in the next releases.

Here's my breeze-dark.css stylesheet to make the html look better:

* { color: #eff0f1; }
a, a * { color: #2980b9; }
a { text-decoration: none; }

edit: updated stylesheeet to color subelements of a

And my editor colour scheme settings in ~/.config/ReText\ project/ReText.conf:

[General]
... snipped ...
highlightCurrentLine=true
lineNumbersEnabled=true
pygmentsStyle=native
styleSheet=/home/cognifloyd/.config/ReText project/breeze-dark.css
useWebKit=true

[ColorScheme]
codeSpans=#da4453
currentLineHighlight=#31363b
lineNumberArea=#31363b
lineNumberAreaText=#bdc3c7
marginLine=#3daee9
markdownLinks=#2980b9

Here are some screenshots of how these colors look with the doc I'm editing right now.

This shows codeSpans, lineNumber*, currentLineHighlight, and markdownLinks:

This shows pygmentsStyle=native:

And this shows the marginLine:

I spent some time looking for options on Edit and Preferences where to change to a dark theme, and found none... Ended up at this ticket, and now I'm following any changes here.

I would suggest adding at least two color schemes to the editor, light and dark, and some guidance on how to tweak those things. I only found the color scheme thing through here :)

How did you get these examples in dark? I tried breeze-dark.css as above and the editor backgound is still white. How did you set background to dark in above screenshots? Are these real or mocks?

[mitya57]

@Mat001 please be sure to add [ColorScheme] section to your ReText configuration file like in @cognifloyd’s excellent comment above.

@Mat001 please be sure to add [ColorScheme] section to your ReText configuration file like in @cognifloyd’s excellent comment above.

And when adding [ColorScheme] doesn't work? I mean, I can manipulate the CSS file and change the preview all I want, but nothing seems to affect the editor window.

(EDIT)
To answer my own question: The reason is because the edit window is controlled by two different things. The first is a QT style sheet that must be pointed to by the appStyleSheet=~/.config/ReText project/style.css as well as the commands included in the config file.

I've followed the steps above to try to get a dark theme:

• Changed ~/.config/ReText\ project/ReText.conf to

[General]
highlightCurrentLine=true
lineNumbersEnabled=true
pygmentsStyle=native
recentFileList=/home/doug/Documents/Notes/Work/LTV EPic Outline.md
styleSheet=/home/doug/.config/ReText\project/breeze-dark.css
useWebKit=true

[ColorScheme]
codeSpans=#da4453
currentLineHighlight=#31363b
lineNumberArea=#31363b
lineNumberAreaText=#bdc3c7
marginLine=#3daee9
markdownLinks=#2980b9

Then created a new file breeze-dark.css with

* { color: #eff0f1; }
a, a * { color: #2980b9; }
a { text-decoration: none; }

• I added this file to ~/.config/ReText\ project/ and then with the ReText app open I went to Editor > Use Webkit Renderer (True)
• I added the breeze-dark.css to the same .config dir and changed the stylesheet entry above to styleSheet=/home/doug/.config/ReText\project/breeze-dark.css

Outcome:

Was hoping to get a dark theme like in the screens in the discussion further up. How can I get to that?

[mitya57]

@gcameron89777 You need to actually change your interface style to some dark style.

As you seem to be using GNOME and not Plasma, so I will recommend the adwaita-qt package (use sudo apt install adwaita-qt to install it on Ubuntu).

To apply the theme, you have the following options:

• Run ReText with -style Adwaita-Dark command-line argument.
• Or export QT_STYLE_OVERRIDE=Adwaita-Dark environment variable.
• Or use qt5ct tool.

[gcameron89777]

Hi @mitya57 thanks for the information. I installed adwaita-qt and added a global variable to my ~/.bashrc file:

sudo apt install adwaita-qt
Reading package lists... Done
Building dependency tree       
Reading state information... Done
adwaita-qt is already the newest version (1.0-2).
The following packages were automatically installed and are no longer required:
  apt-clone archdetect-deb btrfs-tools gir1.2-geocodeglib-1.0
  gir1.2-timezonemap-1.0 gir1.2-xkl-1.0 libdebian-installer4 libfwup1
  libido3-0.1-0 libllvm8 libtimezonemap-data libtimezonemap1 python3-icu
  python3-pam rdate ubuntu-web-launchers
Use 'sudo apt autoremove' to remove them.

doug@doug-XPS-13-9300:~$ echo $QT_STYLE_OVERRIDE 
Adwaita-Dark

I then closed my shell and retext, then opened again. When I opened via Ubuntu apps menu, no change. I tried opening via the terminal only with just 'retext' and it works! May I ask a couple of follow ups?

When running retext in the terminal I got the foloowing warnings:

`Using configuration file: /home/doug/.config/ReText project/ReText.conf
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile`

Do I need to do anything about those?

Is there a forum I can ask general Q's? I looked at Stack Overflow but there's no retext tag. Should I just ask Q's on the repo? My questions might be more general rather than technical?

[mitya57]

When I opened via Ubuntu apps menu, no change.

That is because ~/.bashrc does not apply to the apps menu. Try using ~/.profile as described in Ubuntu help.

libpng warning: iCCP: known incorrect sRGB profile

This was a bug in Qt WebKit which is fixed in 5.212.0 Alpha 3, see qtwebkit/qtwebkit#798. No need to do anything, just ignore it.

Is there a forum I can ask general Q's? I looked at Stack Overflow but there's no retext tag. Should I just ask Q's on the repo? My questions might be more general rather than technical?

You can ask on the repo, but better file a separate issue because this one has other subscribers.

[mitya57]

I have just pushed a commit (5343c00) with which adding custom CSS for dark themes should be no longer needed. Also earlier today I pushed retext-project/pymarkups@4536926026c830b2 which improves support for reStructuredText rendering with dark themes.

So the only remaining bit that needs to be added manually is the ColorScheme block in the configuration file.

[mitya57]

With the current version from master, there should be no need to set ColorScheme for dark themes anymore — they now work out of the box!

I used some colors from @cognifloyd's comment above — thanks a lot and I hope you don't mind.

Please help testing the new version. Any feedback is welcome.
