31 | ;; Thanks to Gregory M. Saunders <saunders@cis.ohio-state.edu> for | |

34 | ;; Thanks go to Andrew V. Klein <avk@rtsg.mot.com> for the code that |
35 | ;; sorts the alist before presenting it to the user (in list-bookmarks | |
36 | ;; and the menu-bar). | |
37 | ||
d22d6453 RS |
38 | ;; And much thanks to David Hughes <djh@harston.cv.com> for many small |
39 | ;; suggestions and the code to implement them (like | |
40 | ;; Bookmark-menu-check-position, and some of the Lucid compatibility | |
41 | ;; stuff). | |

43 | ;; Kudos (whatever they are) go to Jim Blandy <jimb@cs.oberlin.edu> |
44 | ;; for his eminently sensible suggestion to separate bookmark-jump | |
45 | ;; into bookmark-jump and bookmark-jump-noselect, which made many | |
46 | ;; other things cleaner as well. | |
47 | ||

48 | ;; Thanks to Roland McGrath for encouragement and help with defining |
49 | ;; autoloads on the menu-bar. | |

51 | ;; Jonathan Stigelman <stig@key.amdahl.com> gave patches for default |
52 | ;; values in bookmark-jump and bookmark-set. Everybody please keep | |
53 | ;; all the keystrokes they save thereby and send them to him at the | |
54 | ;; end of each year :-) (No, seriously, thanks Jonathan!) | |

71 | ||
72 | ;; bookmark alist format: | |
73 | ;; (... | |
74 | ;; (bookmark-name (filename | |
75 | ;; string-in-front | |
76 | ;; string-behind | |
77 | ;; point)) | |
78 | ;; ...) | |
79 | ;; | |
80 | ;; bookmark-name is the string the user gives the bookmark and | |
81 | ;; accesses it by from then on. filename is the location of the file | |
82 | ;; in which the bookmark is set. string-in-front is a string of | |
83 | ;; `bookmark-search-size' chars of context in front of the point the | |
84 | ;; bookmark is set at, string-behind is the same thing after the | |
85 | ;; point. bookmark-jump will search for string-behind and | |
86 | ;; string-in-front in case the file has changed since the bookmark was | |
87 | ;; set. It will attempt to place the user before the changes, if | |
88 | ;; there were any. | |

90 | ;; The bookmark list is sorted lexically by default, but you can turn |
91 | ;; this off by setting bookmark-sort-flag to nil. If it is nil, then | |
92 | ;; the list will be presented in the order it is recorded | |
93 | ;; (chronologically), which is actually fairly useful as well. | |
