134 After the list is prepared, the hooks `nongregorian-diary-listing-hook',

135 `list-diary-entries-hook', `diary-display-hook', and `diary-hook' are run.
|

136 These hooks have the following distinct roles:
|
|
|
137
|
|
|
138 `nongregorian-diary-listing-hook' can cull dates from the diary
|
|
|
139 and each included file. Usually used for Hebrew or Islamic
|
|
|
140 diary entries in files. Applied to *each* file.
|
|
|
141
|
|
|
142 `list-diary-entries-hook' adds or manipulates diary entries from
|
|
|
143 external sources. Used, for example, to include diary entries
|
|
|
144 from other files or to sort the diary entries. Invoked *once* only,
|
|
|
145 before the display hook is run.
|
|
|
146
|
|
|
147 `diary-display-hook' does the actual display of information. If this is
|
|
|
148 nil, simple-diary-display will be used. Use add-hook to set this to
|
|
|
149 fancy-diary-display, if desired. If you want no diary display, use
|
|
|
150 add-hook to set this to ignore.
|
|
|
151
|
|
|
152 `diary-hook' is run last. This can be used for an appointment
|
|
|
153 notification function."
