Fish/Nushell Dual-Shell Maintenance
Core Mandates
- The Sync Rule: Any change to
config.fish, Fish functions, abbreviations, or aliases MUST be mirrored inconfig.nu. - Fish first: Author in Fish, then translate to Nushell.
- Starship configuration: Keep
starship.tomlunified across both shells.
Technical Standards
1. Mirroring Strategy
| Fish Concept | Nushell Mirror |
| :--- | :--- |
| function | def or def --env |
| abbr / alias | alias |
| set -gx | $env.<NAME> = "..." |
| PATH | $env.PATH (ensure it's updated correctly) |
2. Fish Workflow
- Use
functions -nto list all user functions. - Use
abbr -lto list all abbreviations. - Edit
dot_config/fish/config.fishanddot_config/fish/functions/.
3. Nushell Workflow
- Edit
dot_config/nushell/config.nu. - Ensure custom commands are properly exported.
- Test with
nu -c "your-command".
Anti-Rationalization
| Excuse | Reality | | :--- | :--- | | "I'll sync later" | Drift between shells causes confusing runtime bugs. Sync now. | | "It's just an alias" | Even an alias can change how you interact with the system. Sync it. | | "I don't use Nushell" | The system mandates parallel maintenance. Follow the rule. |
