# title: Gtk2 theme installer
# description: Shows themes in the bookmarks pane for installation
# type: feature
# category: ui
# version: 0.3
# priority: experimental
#
# Downloads a list of Gtk themes and presents it in the bookmarks
# tab under... »themes«. Double clicking will download and install
# a theme right away.
#
# Note that this is primarily meant for Windows, as it unpacks
# *.dll engines if found. Should work on BSD/Linux still, but would
# require setting up .gtkrc, and writeable module_path for engines.
# It only handles Gtk2 themes currently.
#
# Reuses the `conf.theme` setting from the `gtk_theme` plugin, and
# should work in conjunction to it.
#
# The theme repository is a CSV file of:
#   themepkg.zip, theme.png, Title, Author, http://homepage/
# with the packages residing next to it.
#
# Using a repo.json works better however, and would allow to
# integrate it with the regular plugin manager somewhen.
# The bookmark/themes channel provides the nicer UI however.
#
# A theme.zip should contain a structure like:
#    ---------  ---------- -----   ----
#        62937  2016-12-12 16:39   librezlooks.dll
#            0  2016-12-12 16:40   Rezlooks-dark/
#            0  2016-12-03 20:58   Rezlooks-dark/gtk-2.0/
#         5332  2006-06-30 05:28   Rezlooks-dark/gtk-2.0/gtkrc
#    ---------  ---------- -----   ----
# With the dll in the root, and theme files in a named subdir.
# Zips are extracted into the config dir ../streamtuner2/themes/
# and copies left there even.
