Tmux key-binding to open task calender and list tasks
I have been searching for a way to show my Taskwarrior calendar and tasks with a single key-binding in Tmux.
Automatic start of Tmux
I start Tmux from my i3-config with:
exec --no-startup-id $term -e tmux new-session -s workpad
This starts tmux with a session named "workpad".
Configuration of Taskwarrior
I added the following line to my .taskrc:
With this, the command 'task calendar' shows the calender for the current and upcoming months with some nice colors, as well as a list of the tasks, including the due dates.
Configuration of Tmux
After some trial-and-error I came to the following lines in my .tmux.conf:
bind T if-shell 'tmux has-session -t =workpad:=twcal' '' \ 'new-window -n twcal' \; send-keys -t '=workpad:=twcal' \ 'task calendar' C-m \; \ select-window -t =workpad:=twcal
The break-down of this is as folows.
bind T :
bind the command to key [shift]-T
tmux command to do some if-then-else thing
tmux has-session -t =workpad:=twcal':
test if window named 'twcal' exists
if true, do nothing
'new-window -n twcal :
if false, create new window named 'twcal'
start new command after if-then-else thing
send-keys -t '=workpad:=twcal' :
send following command to the window named 'twcal'
'task calendar' C-m :
command to start task calendar followed by [enter] (C-m)
start new command after opening task calendar
select-window -t =workpad:=twcal :
set focus to the window named 'twcal'
This last part (select-window) is necessary when the window named 'twcal' already exists and does not has the focus.
Not rocket science
OK, this is very simple. there are two reasons why I publish this:
- It is blazingly fast
- Test if named window exists is not very easy to find
Also, for me the Taskwarrior calendar followed by the list of tasks including due-dates is very, very useful. And it has nice colors :)
