adding flexibility in view options

[frederikvontrapp]

I am a total hobbyist at this stuff so do tell me if this is dumb or superfluous or whatever.

I enjoy using khal but miss some flexibility in displaying events. Mainly two things:

• I want to look not just days but also weeks or months ahead
• I sometimes want to look back in time

Eg, I want the following command to work:

khal list -3d 2w

which should list everything from 3 days ago up to 2 weeks into the future.

I've made a simple wrapper script that does just that. Works fine. But since it's still a wraparound and feels like the sort of thing that could be incorporated into khal itself, figured I'd post here.

#!/bin/zsh

#input variables start="$1" finish="$2"

#store other arguments shift 2

#build start date if [[ $start == "now" || $start == "yesterday" || $start == "tomorrow" ]]; then khal_start=$start

elif [[ $start =~ ^-?[0-9]+[dwmy]$ ]]; then number="${start%%[dwmy]}" unit="${start: -1}"

case $unit in
	d) unit_full=" days" ;;
	w) unit_full=" weeks" ;;
	m) unit_full=" months" ;;
	y) unit_full=" years" ;;
esac

khal_start=$(date -d "$number$unit_full" "+%Y_%m_%d")

fi

#build finish date if [[ $finish == "now" || $finish == "yesterday" || $finish == "tomorrow" ]]; then khal_finish=$finish

elif [[ $finish =~ ^-?[0-9]+[dwmy]$ ]]; then number="${finish%%[dwmy]}" unit="${finish: -1}"

case $unit in
	d) unit_full=" days" ;;
	w) unit_full=" weeks" ;;
	m) unit_full=" months" ;;
	y) unit_full=" years" ;;
esac

khal_finish=$(date -d "$number$unit_full" "+%Y_%m_%d")

fi

khal list $khal_start $khal_finish $@
