# Race conditions are possible with active usage during application start

# https://github.com/sigoden/argc
# @meta combine-shorts
# @option -M --move Move next window to absolute position (X[%] Y[%]) (requires floating)
# @option -R --resize Resize next window to absolute dimensions (W[%] H[%]) (requires floating)
# @option -W --workspace Move next window to workspace
# @flag -a --active Focus and raise next window (raise requires floating)
# @flag -c --center Center next window (requires floating)
# @flag -e --empty Only launch if workspace is empty (requires workspace)
# @flag -f --float Float next window
# @flag -g --group Add next window to the active group
# @flag -l --lock Lock next window's group
# @flag -m --maximize Maximize next window
# @flag -n --new Add next window to a new group
# @flag -p --pin Pin next window (requires floating)
# @flag -s --fullscreen Fullscreen next window
# @flag -t --tile Tile next window
# @arg commands+ Commands to execute in an exec dispatcher
