Add a new utility script for splitting files into 1GB chunks:
,split-1G - File splitting wrapper
- Splits one or more files into 1GB chunks with numeric suffixes
- Uses split(1) with --bytes=1G for consistent chunk sizes
- Generates 5-digit numeric suffixes (.00000, .00001, etc) for up to 99,999 parts
- Outputs verbose progress information during splitting
- Fails fast with set -e to catch errors during multi-file operations
- Added to tb-scripts package with coreutils as runtime dependency
This is useful for preparing large files for upload to services with file
size limits, or for splitting backups/archives into manageable pieces.
Example usage:
,split-1G large-backup.tar.gz
# Creates: large-backup.tar.gz.00000, large-backup.tar.gz.00001, ...

Add two new shell utility scripts to the custom script packages:
,optipng - Parallel PNG optimization wrapper
- Detects available CPU cores and runs optipng in parallel using xargs
- Accepts optional file arguments, defaults to all *.png in current dir
- Uses maximum compression level (-o7) for best results
- Added to tb-dev-scripts package with optipng as runtime dependency
,zipdir - Quick directory archiving helper
- Creates a zip archive of the current directory
- Names the archive after the directory and places it in parent folder
- Uses maximum compression (-9) with extra attributes excluded (-X)
- Added to tb-scripts package with zip as runtime dependency

This commit introduces two new custom script packages: tb-scripts for
all systems and tb-dev-scripts for development machines. These packages
provide a maintainable way to distribute utility scripts across the
infrastructure with proper dependency management.
Created pkgs/ directory with two script collections:
1. **tb-scripts** - General utilities available on all systems:
- ,jq_reformat: Reformat JSON files in-place with atomic file operations
- ,rename_lower: Convert filenames to lowercase with validation
2. **tb-dev-scripts** - Development-specific tools:
- ,cmake_update_fetchcontent: Update CMake FetchContent dependencies
All scripts have been significantly enhanced from their original versions:
- Proper quoting to handle filenames with spaces
- Secure temporary file creation using mktemp
- Atomic file replacement to prevent data loss
- Input validation and comprehensive error handling
- Usage help with -h/--help flag
- Extensive inline comments explaining each section
- Cleanup traps on error
- Complete rewrite in Python for consistency
- Validates files exist before attempting rename
- Checks if target lowercase filename already exists
- Skips files already lowercase (no-op)
- Descriptive error messages for each failure case
- Usage documentation with examples
- Proper exit codes
- Interactive CMake FetchContent dependency updater
- Recursively finds all CMakeLists.txt files via add_subdirectory()
- Queries GitHub API for latest releases/tags
- Compares semantic versions and commit hashes
- Shows available updates in formatted table
- Prompts for confirmation before applying updates
- Atomic file updates with validation
Scripts are packaged using writeShellApplication with proper dependency
injection via runtimeInputs:
- tb-scripts requires: jq, python3
- tb-dev-scripts requires: python3, git
Dependencies are automatically available in PATH when scripts run,
eliminating manual dependency checks.
Created system module files to import the script packages:
- system/default/scripts.nix: Adds tb-scripts to nixosModules.default
- system/develop/scripts.nix: Adds tb-dev-scripts to nixosModules.develop
Updated flake.nix to import these modules in the appropriate contexts.
- Scripts have proper Nix-managed dependencies
- No manual installation or PATH configuration needed
- Easy to extend with additional scripts
- Scripts are validated with shellcheck during build
- Clear separation between all-systems and dev-only utilities
- Comprehensive error handling and user documentation
