  24. ;;; Commentary:
  25. ;; This file contains the code dealing with plain lists in Org-mode.
  26. ;; The core concept behind lists is their structure. A structure is
  27. ;; a snapshot of the list, in the shape of a data tree (see
  28. ;; `org-list-struct').
  29. ;; Once the list structure is stored, it is possible to make changes
  30. ;; on it that will be mirrored to the real list or to get information
  31. ;; about the list, using accessors and methods provided in the
  32. ;; library. Most of them require the use of one or two helper
  33. ;; functions, namely `org-list-parents-alist' and
  34. ;; `org-list-prevs-alist'.
  35. ;; Structure is eventually applied to the buffer with
  36. ;; `org-list-write-struct'. This function repairs (bullets,
  37. ;; indentation, checkboxes) the list in the process. It should be
  38. ;; called near the end of any function working on structures.
  39. ;; Thus, a function applying to lists should usually follow this
  40. ;; template:
  41. ;; 1. Verify point is in a list and grab item beginning (with the same
  42. ;; function `org-in-item-p'). If the function requires the cursor
  43. ;; to be at item's bullet, `org-at-item-p' is more selective. It
  44. ;; is also possible to move point to the closest item with
  45. ;; `org-list-search-backward', or `org-list-search-forward',
  46. ;; applied to the function `org-item-beginning-re'.
  47. ;; 2. Get list structure with `org-list-struct'.
  48. ;; 3. Compute one, or both, helper functions,
  49. ;; (`org-list-parents-alist', `org-list-prevs-alist') depending on
  50. ;; needed accessors.
  51. ;; 4. Proceed with the modifications, using methods and accessors.
  52. ;; 5. Verify and apply structure to buffer, using
  53. ;; `org-list-write-struct'.
  54. ;; 6. If changes made to the list might have modified check-boxes,
  55. ;; call `org-update-checkbox-count-maybe'.
  56. ;; Computing a structure can be a costly operation on huge lists (a
  57. ;; few thousand lines long). Thus, code should follow the rule:
  58. ;; "collect once, use many". As a corollary, it is usually a bad idea
  59. ;; to use directly an interactive function inside the code, as those,
  60. ;; being independent entities, read the whole list structure another
  61. ;; time.

  3004. list, effectively ignoring its opening and closing lines.
  3005. :ustart, :uend

  3009. :ostart, :oend
  3010. Strings to start and end an ordered list. They can also be set
  3011. to a function returning a string or nil, which will be called
  3012. with the depth of the list, counting from 1.
  3013. :dstart, :dend
  3014. Strings to start and end a descriptive list. They can also be
  3015. set to a function returning a string or nil, which will be
  3016. called with the depth of the list, counting from 1.
  3017. :dtstart, :dtend, :ddstart, :ddend
  3018. Strings to start and end a descriptive term.
  3019. :istart, :iend
  3020. Strings to start or end a list item, and to start a list item
  3021. with a counter. They can also be set to a function returning
  3022. a string or nil, which will be called with the depth of the
  3023. item, counting from 1.
  3024. :icount
  3025. Strings to start a list item with a counter. It can also be
  3026. set to a function returning a string or nil, which will be
  3027. called with two arguments: the depth of the item, counting from
  3028. 1, and the counter. Its value, when non-nil, has precedence
  3029. over `:istart'.
  3030. :isep
  3031. String used to separate items. It can also be set to
  3032. a function returning a string or nil, which will be called with
  3033. the depth of the items, counting from 1. It always start on
  3034. a new line.
