1802278a JB |
125 | |
126 | `nongregorian-diary-listing-hook' can cull dates from the diary | |
127 | and each included file. Usually used for Hebrew or Islamic | |
128 | diary entries in files. Applied to *each* file. | |
129 | ||
130 | `list-diary-entries-hook' adds or manipulates diary entries from | |
131 | external sources. Used, for example, to include diary entries | |
6e72e795 RS |
132 | from other files or to sort the diary entries. Invoked *once* only, |
133 | before the display hook is run. | |
1802278a | 134 | |
6e72e795 RS |
135 | `diary-display-hook' does the actual display of information. If this is |
136 | nil, simple-diary-display will be used. Use add-hook to set this to | |
137 | fancy-diary-display, if desired. If you want no diary display, use | |
138 | add-hook to set this to ignore. | |
139 | ||
