Tide: Color caching breaks Fish 4.3+ auto theme switching

[simono]

Problem

Tide's _tide_pwd.fish and fish_prompt.fish cache colors at function definition time, preventing dynamic theme switching in Fish 4.3+.

Impact

When color variables are changed (e.g., switching between light/dark themes), the prompt colors don't update automatically. This breaks Fish's auto theme switching feature introduced in 4.3+.

Affected Code

• _tide_pwd.fish: Lines 1-3 cache color variables at definition
• fish_prompt.fish: Line 25 caches colors
• _tide_cache_variables: Contributes to the caching behavior

Workaround

After changing color variables, you must manually run:

tide reload

This forces tide to re-read the color variables and update the prompt.

Status

This issue appears to be unreported upstream in the tide project.
