# This script makes some assumptions about where things are:
#
# Apache subdirectory for generated tiles, json and html files, etc.
APACHE_SUBDIR=/var/www/html/vector
#
# File extension of json files is assumed to be ".json";
# File extension of html file is assumed to be ".html".
# -----------------------------------------------------------------------------
# This script removes a map style from below apache.
# It is a companion to
# https://github.com/SomeoneElseOSM/SomeoneElse-vector-web-display/blob/main/svwd_into_apache.sh
# which is the matching "install" script and
# https://github.com/SomeoneElseOSM/SomeoneElse-vector-extract/blob/main/sve_delete.sh
# https://github.com/SomeoneElseOSM/SomeoneElse-vector-extract/blob/main/sve_into_apache.sh
# which do the same thing, but delete/install generated map tiles.
# -----------------------------------------------------------------------------
# Then (as root) run this script, with the following parameters.
# These must not contain spaces.  Full paths, no "~".
#
# Parameter: For example:                                                   Meaning:
# $1         omt_ny_1                                                       name of this deployment.
# $2         svwd01                                                         Name of first part of sprite files.

# Set e.v.s for these parameters

# -----------------------------------------------------------------------------
# Now we have all the information we need.
# Delete the vector tiles that we installed

# Delete the spec.json

#
# -----------------------------------------------------------------------------
# We don't delete fonts files below main Apache directory.
# It is expected that most styles will share fonts
# -----------------------------------------------------------------------------
# -----------------------------------------------------------------------------
# Delete the style.json

#
# -----------------------------------------------------------------------------
# Delete the sprite files
# We definitely expect "normal" and "@2x" versions.
# I'm guessing that "@3x" and "@4x" versions are used by higher resolution
# displays.
