jpm-tasks-view (jptv)

Suppose the content of a project.janet is:

(declare-project
  :name "nice-project"
  :description "A nice project in Janet")

(task "task-a" []
  :tags [:blue]
  (os/execute ["ls"] :p))

(task "task-b" []
  :tags [:green :yellow]
  (os/execute ["df"] :p))

(task "task-c" []
  :tags [:red :blue]
  (os/execute ["ps"] :p))

With jptv, one can do:

$ jptv --tags
blue
green
red
yellow

$ jptv blue
task-a
task-c

$ jptv green
task-b

$ jptv --tasks
task-a
task-b
task-c

$ jptv
blue
  task-c
  task-a

green
  task-b

red
  task-c

yellow
  task-b
