;; How to use:
;; 1. Customize org-toodledo-userid and org-toodledo-password
;; 2. Open a blank org file.
;; 3. Call org-toodledo-initialize-org
;; Call org-toodledo-update to bring in new/updated tasks (skips locally modified tasks newer than updated)
;; Call org-toodledo-sync-task to create or update the current task
;; Call org-toodledo-delete-current-task to delete the current task
;;
;; Doesn't do lots of error trapping. Might be a good idea to version-control your Org file.
;;
;; TOODLEDO ATTRIBUTES and how they are bi-directionally handled
;; Context: Handled by tags (ex: :@work: :@errands:)
;; - will create new contexts if necessary
;; Task status: Mapped to TODO state.
;; See org-toodledo-status-to-string and org-toodledo-parse-current-task for the mapping
;; You will probably want something like this in your ~/.emacs:
;; (setq org-todo-keywords
;; '((sequence
;; "TODO(t)" ; next action
;; "PLAN(-)"
;; "STARTED(s)"
;; "WAITING(w@/!)"
;; "POSTPONED(p)" "SOMEDAY(s@/!)" "|" "DONE(x!)" "CANCELLED(c@)")
;; (type "DELEGATED(d@!)" "DONE(x)")))
;; Length: Mapped to effort
;; Priority: Mapped to [#A], [#B], or [#C]. (TODO: Change this to five levels of priority to match Toodledo)
;; Start date: Mapped to "SCHEDULED"
;; Due date: Mapped to "DEADLINE"
;; Tags: Mapped to tags
;; Note: Mapped to todo text. May get confused by asterisks, so don't use any starting asterisks in your body text.
;; (or anything that looks like an Org headline).
;; Completed: Mapped to DONE todo state.
;;
;; TODO:
;; - [ ] Double-check new/changed/deleted task updating, still seems buggy
;; - [ ] Test, test, test - maybe make test harness?
;; - [ ] Move status<->string mapping to a variable - lookups are better than logic
;; - [ ] Make sure sync timestamps aren't getting updated more often than needed
;; - [ ] Suggest some kind of hook to make it easier to mark a task as locally modified
