#compdef borg borgfs -P -value-,BORG_*,-default-

# Zsh completion for Borg Backup 1.1.17.
#
# Recommended _borg specific settings:
#
#   zstyle -e ':completion:*:*:borg-*:argument-rest:*' tag-order \
#     '[[ $words[CURRENT] == -* ]] && reply=( "! archives archive-files" "-" )'
#   zstyle ':completion:*:*:(borg|-value-,BORG_)*' sort false
#   zstyle ':completion:*:*:borg-config:argument-2:keys' list-grouped false
#   zstyle ':completion:*:*:borg-*:*' gain-privileges true
#   zstyle ':completion:*' fake-parameters 'BORG_REPO:scalar'
#
# Custom styles:
#
# archive-description-format
#   Default: `{archive:<36} {time} [{id}]`.
# archive-sort
#   In which order archive names should be listed.
#   Possible values are: `inverse`, `timestamp`, `name`, `id`.
# file-description-format
#   Default: `{mode} {user:6} {group:6} {size:8d} {mtime} {path}{extra}`.
# path-style-selector
#   Style selector used to select a path (when Borg would use either `pp` or `pf`).
#   Default: `fm`.
# repository-suffix
#   This boolean style controls whether to add the `::` auto-removable suffix to a repository.
#   Default: `true`.
