Problem Statement

It is now impossible to reload settings of a running cloud code instance.

Proposed Solution

We have integrated CC in a framework with tmux and would like to reload with SIGUSR1 the theme configuration (and any other setting that is suitable) that we have changed with our tooling so that the running process picks up the new settings.json

Alternative Solutions

Priority

Low - Nice to have

Feature Category

Interactive mode (TUI)

Use Case Example

When changing dark mode a script is run to send SIGUser1 to running cloud code instances, making them pick up settings that can be reloaded on the fly.
