Single-script builder (nosignal.sh) that turns a stock Arch Linux ISO into a fully-offline installer for a themed Hyprland + caelestia (Quickshell) desktop: matching SDDM greeter, Btrfs/Limine bootable snapshots, chwd-style GPU detection, and a curated "os updates" layer (keybind cheatsheet, settings panels, system polish, on-box management skill). See README.md. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# NoSignal — fish → bash migration (Omarchy bash setup)
|
|
|
|
Switches this Caelestia/NoSignal box from the fish shell to **bash, configured to
|
|
match [Omarchy](https://github.com/basecamp/omarchy)**. Self-contained so it
|
|
survives a wipe — copy this folder back with the rest of Downloads and run the
|
|
installer.
|
|
|
|
## Install
|
|
|
|
```sh
|
|
sh ~/Downloads/fish-to-bash/install-fish-to-bash.sh
|
|
```
|
|
|
|
Idempotent. Open a **new** terminal afterwards to land in bash.
|
|
|
|
## What it does
|
|
|
|
| Step | Effect |
|
|
|------|--------|
|
|
| Vendor `bash/` tree | Copied verbatim from Omarchy to `~/.local/share/omarchy/default/bash/` (`rc`, `shell`, `aliases`, `envs`, `init`, `functions`, `inputrc`, `completions`, `fns/*`) |
|
|
| `~/.bashrc` | Omarchy's template; sources the tree above. Existing `~/.bashrc` backed up to `~/.bashrc.pre-omarchy` |
|
|
| kitty | `~/.config/kitty/kitty.conf`: `shell fish` → `shell bash` |
|
|
| foot | `~/.config/foot/foot.ini`: `shell=fish` → `shell=bash` |
|
|
| Hyprland helpers | `wsaction.fish` & `configs.fish` replaced with bash ports (same filenames, bash shebang) so the stock keybinds keep working |
|
|
|
|
## Why the layout matches Omarchy exactly
|
|
|
|
The vendored files are byte-for-byte Omarchy and live at Omarchy's own path
|
|
(`~/.local/share/omarchy/...`). That means: (a) the prompt/aliases/history/
|
|
completion behaviour is identical to Omarchy, and (b) you can refresh them from
|
|
upstream by re-copying `default/bash/` with no edits. `envs` sets
|
|
`OMARCHY_PATH` and prepends `~/.local/bin` to `PATH` (so the keybind-help
|
|
scripts resolve too). References to omarchy-only tools (`omarchy`, `mise`,
|
|
`opencode`, `tdl`, `gum`, …) are all guarded with `command -v` or are function
|
|
definitions, so missing tools are harmless until you actually call them.
|
|
|
|
## NoSignal-specific additions (the only deviations from stock Omarchy)
|
|
|
|
- `~/.bashrc` exports `EDITOR=nvim` if unset (Omarchy sets this in `uwsm/env`,
|
|
which we don't manage here).
|
|
- `~/.bashrc` runs `cat ~/.local/state/caelestia/sequences.txt` so the terminal
|
|
picks up Caelestia's dynamic colour scheme.
|
|
|
|
## Notes / things that changed from the old fish config
|
|
|
|
- **`ga` / `gd` now mean Omarchy's git-worktree helpers**, not the old fish
|
|
abbreviations (`git add .` / `git diff`). Other git shortcuts: `g`, `gcm`,
|
|
`gcam`, `gcad`.
|
|
- **direnv** was hooked in the old fish config; Omarchy's bash doesn't include
|
|
it. Add `eval "$(direnv hook bash)"` to the bottom of `~/.bashrc` if you want
|
|
it back.
|
|
- The **fish package is left installed** (it may be pulled in as a Caelestia
|
|
dependency). Nothing interactive uses it anymore. Remove it only after
|
|
confirming nothing else needs it: `sudo pacman -Rns fish`.
|
|
- The fish config dir (`~/.config/fish`, a Caelestia symlink) is left in place
|
|
but unused.
|
|
|
|
## Requirements
|
|
|
|
`bash`, and ideally `starship`, `zoxide`, `eza`, `fzf`, `bat` for the full
|
|
Omarchy experience (all guarded — bash works without them).
