Automatic Dark Theme

Could it be possible to add a new theme choosing between dark and light depending on the system’s theme on macOS Mojave and later ?

For instance light theme is better at day but dark theme is better for reading at night. macOS Catalina already has a feature that changes the theme depending on the time of the day. Is it possible for Mailspring to adapt it’s with Catalina’s ?

Thanks

Dynamic Theme Changing

The Problem
Currently you have to manually switch between Light theme and Dark theme.

Proposed Solution
Changing the theme automatically can be done in many different ways. I think the best approach will be the user choosing a time period for when a particular theme to be chosen. For example, from 7 AM to 7 PM, Mailspring will be using a Light theme, and from 7 PM to 7 AM, Mailspring will be using a Dark theme.

Alternative Solutions
Another way will be to look at the system theme and deciding based on that. For example, on Windows, Mailspring can check a Registry value called “AppsUseLightTheme” located at “HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize” And if it’s set on 0, that means Windows is using Dark Mode, and if it’s set to 1, that means Windows is using Light mode.

Electron has a nice guide on how to integrate with the OS level theme to detect light/dark modes: Dark Mode | Electron

Hi, are there any updates on whether this is planned to be implemented? Thanks

please i specifically installed this for the theme

It would be great if Mailspring would automatically switch between light and dark theme based on the user’s system setting. Almost every other app I use has this functionality.

Would definitely love this feature, and a lot of apps are already doing it (sticking with whatever the system elects as the transition point from light/dark)

I was made a bash file, execute it via keyboard shortcut, to switch light/dark mode in Ubuntu 22.04.

With these lines below, switch Mailspring to dark theme:

pkill mailspring
sed -i ‘50 s/light/dark/’ ~/.config/Mailspring/config.json
mailspring -b

… and with these to light theme:

pkill mailspring
sed -i ‘50 s/dark/light/’ ~/.config/Mailspring/config.json
mailspring -b

Works excellent for my needs, maybe will be helpful for others…
