# ========================================================================
# Run this bash script in this folder to make just this folder's gallery:
#
#   ~/.../thumbspage/examples/trnpix$ 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. 
# This could use 2.3 input config args instead of <<EOF shell magic.
#
# This REGENERATES the external trnpix demo stored elsewhere in a website 
# folder; it won't work unless that website folder is present.   This now
# also copies the demo's {_generate, _publish}.sh, but with double "_".
#
# Caveat: as coded, these demos have the hosting site's analytics code
# embedded in them; please don't post them online verbatim.
#
# Caveat: trnpixcopy's setting must be changed for each new release #.
#
# Update [2.3]: this now runs a subscript, trnpix/_generate.sh, to remake
# trnpix content, instead of a command here which is apt to fall out of
# sync.  The subscript's command looks like this today (but may change!):
#
#   python3 $C/thumbspage/thumbspage.py . \
#              useDynamicIndexLayout=False \
#              inputCleanThumbsFolder=True inputThumbsPerRow=4 \
#              inputThumbMaxSize=100 inputUseViewerPages=True \
#              popupFgColor=\'tan\' \
#              popupOpacity=0.45
#
# Its former version was already out of synch when this was modified:
#   python3 ../../thumbspage.py $trnpix <<-EOF ... EOF
#
# Update [2.3]: results-2.3/__{generate, publish}.sh is copies of 
# trnpix's _{generate, publish}.sh build scripts.
#
# Update [2.3]: trnpix now builds both fixed and dynamic index pages,
# with html files and thumbs+viewer folders for both, and builds its
# HEADER.html from its _HEADER.html with a tag replace; this grabs all.
#
# Update [3.0]: Dynamic index layout is now the default, so trnpix's
# fixed variant is now just a demo.  Because it uses fully explicit
# cmd arg configs, there's nothing to adjust for the new layout.
# [3.0] also renamed image files with spaces; use new names here
# (and spaces in filenames cause all sorts of kinipshins in Bash...).
