# ODS — Rsync Utilities

# ============================================================================

# Part of: lib/

# Purpose: Shared rsync functions with progress indicators

# Expects: None (standalone utility)

# Provides: rsync_with_progress()

# Usage:

# . "$ODS_DIR/lib/rsync.sh"

# rsync_with_progress "$src" "$dest" "Optional label"

# ============================================================================

# Rsync with progress indicator

# Args:

# $1 - source path

# $2 - destination path

# $3 - optional label (default: "Copying")

rsync_with_progress() {

local src="$1"

local dest="$2"

local label="${3:-Copying}"

# Prefer the caller's styled logger when it exists. log_info is a *function*

# in the scripts that source this lib (ods-backup.sh, ods-restore.sh), so it

# must be probed with `declare -F`, not `${log_info:-}` (which only ever sees

# a variable and is always empty — the styled path was previously dead code).

if declare -F log_info >/dev/null 2>&1; then

log_info "$label..."

else

echo "[INFO] $label..."

# Use --info=progress2 for compact single-line progress updates

# Fallback to basic rsync if progress2 not supported

if rsync --help 2>/dev/null | grep -q "info=progress2"; then

rsync -a --delete --info=progress2 "$src" "$dest"

else

# Fallback: use --progress for older rsync versions

rsync -a --delete --progress "$src" "$dest" 2>/dev/null || rsync -a --delete "$src" "$dest"
