# Example for $XDG_CONFIG_HOME/nsxiv/exec/win-title
# Called by nsxiv(1) whenever any of the relevant information changes.
# The output is set as nsxiv's window title.
#
# Arguments, "Optional" arguments might be empty:
#   $1: resolved absolute path of the current file
#   $2: current file number
#   $3: total file number
#   $4: image width (Optional: Disabled on thumbnails mode)
#   $5: image height (Optional: Disabled on thumbnails mode)
#   $6: current zoom (Optional: Disabled on thumbnails mode)
#
# The term file is used rather than image as nsxiv does not
# precheck that the input files are valid images. Total file
# count may be different from the actual count of valid images.
