TRACKING: Support more Themes

[neiljp]

Since themes are now isolated, we hope that adding a new theme should be easier for a contributor!

Please review our existing theme documentation and theme source files in zulipterminal/themes/
(currently all themes are integrated in the source, until #1067)

If you have questions that are not answered by the documentation in that location, or our other documentation, please do ask in the #zulip-terminal stream on chat.zulip.org!

Themes we could consider adding/developing:

• dracula [WIP at Dracula theme #1138]
• nord [WIP at Nord theme #1139]
• gruvbox light
• solarized light
• solarized dark [WIP at WIP: Themes: Minimal working solarized dark theme (via #1175) #1345]

(please discuss in the stream first, if you think of others and want to work on them)

Things to consider:

• please include a reference to the theme origin, ie. where you found the colors to use
• we aim to work in different color depths, so try testing those as well as the default 256-color depth
• some styles have common named colors; it would be good to reuse these
• supporting syntax highlighting would be useful, but could be worked on later

NOTE: Since some themes have WIP (work in progress) PRs already, please check their status first; it is then normally good to use tools/fetch-pull-request to fetch these and build upon them if they are not in active development. You may need to rebase them against main to resolve conflicts.

NOTE: To support multiple contributors working on this, please do not claim this issue directly - it would be useful if you only work on one of these yourself and leave other themes for others to work on.

Hello, i'm new to contributing to OS projects, and would like to develop the Nord Theme for Zulip Terminal.

I would like to be inspired in the VS Code Nord Theme:

Example

[neiljp]

Hi @felipecpassos! Welcome to the project!

For the colors themselves, you may wish to refer to https://www.nordtheme.com/
For application of the colors, that site may also have insights as to which kinds of UI elements might fit best with different colors?

Other than the colors and assigning them to the UI styles in a new theme file, you'll need to add the connections for the new theme to enable it to be selected at run-time, though that should be a case of looking for the names of existing themes and adding in your new theme file name.

Thank you for the welcome @neiljp

I would like to develop the Dracula theme for the Zulip terminal.
I would refer to their official documentation https://draculatheme.com/
As mentioned in the issue description, I could not find any existing stream on this issue!

Hi all,
Can I please work on gruvbox light theme?
@zulipbot claim

[neiljp]

@Dishti-Oberai Hopefully you saw that @amanagr and myself responded in #zulip-terminal.

Zulipbot does not appear to be working right now, at least in this repository, but in any case this is an issue with many elements and so multiple people are working on. A comment on GitHub is good to indicate you're working on it :)

[neiljp]

@CypherpunkSamurai I'm not as familiar with the OneDark vim theme, but it seems possible to add. There is some documentation in the themes folder for adding themes, though it may need updating for some theme features which were added over the last Summer. For a theme which requires its own colors, I would suggest you work from a template theme like gruvbox.

Thank you @neiljp , I will comment on GitHub and CZO in case I face any challenges while working on this issue.
