I did your test wuth a null regexp It is a regexp problem! Org-mode has two variables: org-deadline-string and org-scheduled-string (see below) and I want to match tasks which have a timestamp, ie satisfies the org-ts-regexp2 BUT DO NOT have org-deadline-string NOR org-scheduled-string I tried (org2rem-pure-timestamps-string (concat "\\(" org-deadline-string "\\|" org-scheduled-string "\\)\\{0\\}")) in order that a regexp such as "\\(org-deadline-string\\|org-scheduled-string\\)\\{0\\}" would match only zero {0} occurrences of (org-deadline-string|org-scheduled-string) but this seems to be a mistake. Any hint?? Daniel --- Details --- org-deadline-string is a variable defined in `org.el'. Its value is "DEADLINE:" org-scheduled-string is a variable defined in `org.el'. Its value is "SCHEDULED:" org-ts-regexp2 is a variable defined in `org.el'. Its value is "<\\(\\([0-9]\\{4\\}\\)-\\([0-9]\\{2\\}\\)-\\([0-9]\\{2\\}\\) +\\([^]-+0-9> \n ]*\\)\\( \\([0-9]\\{2\\}\\):\\([0-9]\\{2\\}\\)\\)?\\)[^>\n]\\{0,16\\}>" Documentation: Regular expression matching time stamps, with groups. 2009/1/10 Olaf Dietsche > > Hi Daniel, > > "Daniel Martins" writes: > > > Me, as an ex-Fortran77 programmer, am suffering a lot with emacs lisp. > > With time, it'll get better. > > > After o couple of hours trying to catch all timestamps outside SCHEDULE: > and > > DEADLINE: lines I gave up and ask for help > [...] > > I tried to catch all timestamps outside SCHEDULE: and DEADLINE: > > using something like > > > > (org2rem-pure-timestamps-reminders > > (org2rem-list-reminders > > (concat "\\(" org-deadline-string "\\|" > > org-scheduled-string "\\)\\{0\\}"))) > > > [...] > > I tried first to create a local variable > > > > ;;; (org2rem-pure-timestamps-string > > ;;; (concat "\\(" org-deadline-string "\\|" > > ;;; org-scheduled-string "\\)\\{0\\}")) > > > > ;;; (org2rem-pure-timestamps-reminders > > ;;; (org2rem-list-reminders org2rem-pure-timestamps-string) > > ;;; ) > > > > but it did not work either. > > > > I am probably having > > > > Any help for this stupid doubt? > > I don't think, this is a question of a local variable vs. inlining the > regexp.
