Create for me a script that does the following.
|
||||
The script should run on any nixos machine.
|
||||
#!/usr/bin/env bash
|
||||
set -euo pipefail
|
||||
|
||||
For git use REPO_URL="https://gitea.data-pro.nu/henrov/nixos.git"
|
||||
For html use https://gitea.data-pro.nu/henrov/nixos/archive/main.zip

### Step 5 — Replace file contents
|

### ─────────────────────────────
|
||||
|
||||
## Step 4 — Rename files and folders
|
||||
echo "Replacing content..."
|
||||
|
||||
Perform the following renames recursively under `~/Droidnix`, processing deepest paths first to avoid conflicts:
|
||||
# 5.1 generated/ henrov → user
|
||||
if [ -d "$TARGET_DIR/generated" ]; then
|
||||
find "$TARGET_DIR/generated" -type f -exec sed -i "s/henrov/$USER_NAME/g" {} +
|
||||
fi
|
||||
|
||||
- **4.1** Rename any file or folder whose name contains `traveldroid`, replacing it with `$HOSTNAME`
|
||||
# 5.3 path replacement (skip binaries loosely)
|
||||
find "$TARGET_DIR" -type f -exec grep -Iq . {} \; -print | while read -r file; do
|
||||
sed -i "s#~/Repos/nixos/Droidnix#~/Droidnix#g" "$file" || true
|
||||
done
|
||||
|
||||
- **4.2** Rename any file or folder whose name contains `henrov`, replacing it with `$USER`
|
||||
# 5.4 traveldroid → hostname everywhere
|
||||
find "$TARGET_DIR" -type f -exec grep -Iq . {} \; -print | while read -r file; do
|
||||
sed -i "s/traveldroid/$HOSTNAME/g" "$file" || true
|
||||
done
|
||||
|
||||
## Step 5 — Replace strings in file contents
|
||||
# 5.2 & 5.6 README.org block replacement
|
||||
README="$TARGET_DIR/README.org"
|
||||
|
||||
Perform the following text substitutions:
|
||||
if [ -f "$README" ]; then
|
||||
awk -v user="$USER_NAME" -v host="$HOSTNAME" '
|
||||
BEGIN {inblock=0}
|
||||
|
||||
- **5.1** In all files under `~/Droidnix/generated/`, replace every occurrence of `henrov` with `$USER`
|
||||
{
|
||||
if ($0 ~ /^\*\* =/) inblock=1
|
||||
if (inblock == 1) {
|
||||
gsub("henrov", user)
|
||||
gsub("traveldroid", host)
|
||||
}
|
||||
print $0
|
||||
if ($0 ~ /^#\+END_SRC/) inblock=0
|
||||
}' "$README" > "$README.tmp" && mv "$README.tmp" "$README"
|
||||
fi
|
||||
|
||||
- **5.2** In `~/Droidnix/[README.org](http://README.org)`, replace every occurrence of `henrov` with `$USER`, but **only within blocks** that begin with the string `** =` and end with a line matching `#+END_SRC`. Leave all text outside these blocks unchanged.
|
||||
### ─────────────────────────────
|
||||
### Step 6 — Hardware config
|
||||
### ─────────────────────────────
|
||||
HOST_DIR="$TARGET_DIR/generated/hosts/$HOSTNAME"
|
||||
mkdir -p "$HOST_DIR"
|
||||
|
||||
- **5.3** In all files under `~/Droidnix/` (recursively, excluding binary files), replace every occurrence of `~/Repos/nixos/Droidnix` with `~/Droidnix`
|
||||
echo "Generating hardware configuration..."
|
||||
sudo nixos-generate-config --show-hardware-config > \
|
||||
"$HOST_DIR/hardware-configuration.nix"
|
||||
|
||||
- **5.4.** In all files under `~/Droidnix`, replace every occurrence of `traveldroid` with `$HOSTNAME`
|
||||
### ─────────────────────────────
|
||||
### Step 7 — Inject hardware into README.org
|
||||
### ─────────────────────────────
|
||||
|
||||
- **5.6** In `~/Droidnix/[README.org](http://README.org)`, replace every occurrence of `traveldroid` with `$HOSTNAME`, but **only within blocks** that begin with a line matching `** =` and end with a line matching `#+END_SRC`
|
||||
if [ -f "$README" ]; then
|
||||
awk -v file="$HOST_DIR/hardware-configuration.nix" '
|
||||
BEGIN {inblock=0}
|
||||
|
||||
## Step 6 — Generate hardware configuration
|
||||
{
|
||||
if ($0 ~ /^#\+BEGIN_SRC nix :tangle generated\/hosts\/\$/) {
|
||||
inblock=1
|
||||
print $0
|
||||
|
||||
Create the directory `~/Droidnix/generated/hosts/$HOSTNAME/` if it does not already exist.
|
||||
while ((getline line < file) > 0) {
|
||||
print line
|
||||
}
|
||||
close(file)
|
||||
next
|
||||
}
|
||||
|
||||
Run the following command and write its output to `~/Droidnix/generated/hosts/$HOSTNAME/hardware-configuration.nix`:
|
||||
if (inblock == 1 && $0 ~ /^#\+END_SRC/) {
|
||||
inblock=0
|
||||
}
|
||||
|
||||
```bash
|
||||
if (inblock == 0) print $0
|
||||
}' "$README" > "$README.tmp" && mv "$README.tmp" "$README"
|
||||
fi
|
||||
|
||||
sudo nixos-generate-config --show-hardware-config
|
||||
### ─────────────────────────────
|
||||
### Step 8 — Build system
|
||||
### ─────────────────────────────
|
||||
cd "$TARGET_DIR"
|
||||
sudo nixos-rebuild switch --flake ".#$HOSTNAME"
|
||||
|
||||
```
|
||||
|
||||
## Step 7 — Update [README.org](http://README.org) with generated hardware configuration
|
||||
|
||||
In `~/Droidnix/[README.org](http://README.org)`, locate the block that begins with exactly this line:
|
||||
|
||||
```
|
||||
|
||||
#+BEGIN_SRC nix :tangle generated/hosts/$HOSTNAME/hardware-configuration.nix :noweb yes :mkdirp yes :eval never
|
||||
|
||||
```
|
||||
|
||||
and ends with the next line containing exactly `#+END_SRC`.
|
||||
|
||||
Replace everything between (but not including) those two boundary lines with the full contents of `~/Droidnix/generated/hosts/$HOSTNAME/hardware-configuration.nix`.
|
||||
|
||||
## Step 8 — Build and activate the NixOS configuration
|
||||
|
||||
Change directory to `~/Droidnix` and run:
|
||||
|
||||
```bash
|
||||
|
||||
sudo nixos-rebuild switch --flake .#$HOSTNAME
|
||||
|
||||
```
|
||||
|
||||
## Step 9 — Inform the user
|
||||
|
||||
Print the following message:
|
||||
|
||||
```
|
||||
### ─────────────────────────────
|
||||
### Step 9 — Done
|
||||
### ─────────────────────────────
|
||||
cat <<EOF
|
||||
|
||||
Installation complete. Please reboot your system.
|
||||
|
||||
After rebooting, any changes to your NixOS configuration must be made in
|
||||
|
||||
~/Droidnix/[README.org](http://README.org). Before rebuilding, first tangle the org file using:
|
||||
|
||||
emacs --batch --no-init-file ~/Droidnix/[README.org](http://README.org) \
|
||||
~/Droidnix/README.org. Before rebuilding, first tangle the org file using:
|
||||
|
||||
emacs --batch --no-init-file ~/Droidnix/README.org \
|
||||
--eval "(require 'org)" \
|
||||
|
||||
--eval "(require 'ob-tangle)" \
|
||||
|
||||
--eval "(find-file \"[README.org](http://README.org)\")" \
|
||||
|
||||
--eval "(find-file \"README.org\")" \
|
||||
--eval "(with-temp-message \"\" (org-babel-tangle))" \
|
||||
|
||||
--eval "(with-temp-message \"\" (org-html-export-to-html))"
|
||||
|
||||
Then rebuild with:
|
||||
|
||||
cd ~/Droidnix && sudo nixos-rebuild switch --flake .#$(hostname)
|
||||
|
||||
```

||||
