# =========================================================================
# Run this bash script in this folder to make just this folder's galleries:
#
#   ~/.../thumbspage/examples/dynamiclayout$ bash _generate.sh
#
# To make all examples, run the script ../../build/generate-examples.py,
# which runs this script and all others like it.  This automates console 
# inputs, but requires a Unix-style bash shell; extrapolate for other 
# shells or run thumbspage manually elsewhere per _HOW-MADE.txt here. 
#
# Unlike examples/trnpix, this does NOT regenerate trnpix's own content,
# but simply copies out its images, header, and footer, and builds its
# own galleries here with commands that differ from those of trnpix.
#
# Update: as of 2.2, this script could use setting=value config arguments
# in its thumbspage command line, instead of editing the config file with 
# a sed command.  The latter is retained here as an example of former
# usage, but also see ahead for an outline of the new 2.2+ alternative.
# See also ../2.2-upgrades/config-args-demo.sh for a comprehensive demo.
#
# Update: as of 2.3, console inputs can be provided with input-override 
# config settings, in the config file or config arguments; see ahead.
# 2.3 also supports popup color configs, but inherit from the page here.
#
# Note: make-narrow-labels.py' enumerate() counter creates unique IDs,
# but includes non-image files that don't show up in the gallery.
#
# Caveat: as coded, the subfolder demos wind up with the hosting site's
# analytics code embedded in them; please don't posts them online verbatim.
#
# Update: the make-narrow-labels.py now copies over and renames 2.3 .note 
# files too, else they would appear in the wide demo only (subtly indeed).
#
# Update: trnpix now builds its HEADER.html twice, by replacing a tag 
# in _HEADER.html; this script will grab the second of the two built.
