# Configuration for the low-density software chooser
---
# The packagechooser writes a GlobalStorage value for the choice that
# has been made. The key is *packagechooser_<id>*. If *id* is set here,
# it is substituted into the key name. If it is not set, the module's
# instance name is used; see the *instances* section of `settings.conf`.
# If there is just one packagechooser module, and no *id* is set,
# resulting GS key is probably *packagechooser_packagechooser*.
#
# The GS value is a comma-separated list of the IDs of the selected
# packages, or an empty string if none is selected.
#
# id: ""

# Software selection mode, to set whether the software packages
# can be chosen singly, or multiply.
#
# Possible modes are "optional", "required" (for zero or one)
# or "optionalmultiple", "requiredmultiple" (for zero-or-more
# or one-or-more).
mode: required

# Items to display in the chooser. In general, this should be a 
# pretty short list to avoid overwhelming the UI. This is a list
# of objects, and the items are displayed in list order.
#
# Each item has an id, which is used in setting # the value of 
# *packagechooser_<module-id>*). The following fields
# are mandatory:
#
#  - *id* ID for the product. The ID "" is special, and is used for
#    "no package selected". Only include this if the mode allows
#    selecting none.
#  - *package* Package name for the product. While mandatory, this is
#       not actually used anywhere.
#  - *name* Human-readable, but untranslated, name of the product.
#  - *description* Human-readable, but untranslated, description.
#  - *screenshot* Path to a single screenshot of the product. May be
#       a filesystem path or a QRC path (e.g. ":/images/no-selection.png").
#
# Use the empty string "" as ID / key for the "no selection" item if
# you want to customize the display of that item as well.
