Total for tasks matching regex and date range

[jakubzloczewski]

I need displaying total duration for given regex and date range.

Use case:
I'm working on task "large task". Then on task "small task in the middle" and then return to "large task".
I would like to see how much time I spent on "large task".

(I found solution in the middle of writing this issue and decided to leave it as a note for others.)

Solution:
t d -g "large task" -s "yesterday" -e "now"
