(icalendar-version): Increase to 0.08. (icalendar--split-value): Change name of work buffer. (icalendar--get-weekday-abbrev): Return nil on error. (icalendar--date-to-isodate): New function. (icalendar-convert-diary-to-ical) (icalendar-extract-ical-from-buffer): Use only two args for make-obsolete (XEmacs compatibility). (icalendar-export-file, icalendar-import-file): Blank at end of prompt. (icalendar-export-region): Doc fix. If error, return non-nil and write errors to buffer ` *icalendar-errors*'. Use correct weekday for weekly recurring events. Check whether date has been parsed for ordinary events. Make weekly events start in the year 2000. DTEND is non-inclusive, shift end date by one day if necessary (not for entries that have date and time). Rename local let variables: oops -> found-error, datestring -> startdatestring.

|
|
|
;; 0.07 onwards: see lisp/ChangeLog
|
|
|
|
;; 0.06: Bugfixes regarding icalendar-import-format-*.
|
|
;; Fix in icalendar-convert-diary-to-ical -- thanks to Philipp
|
|
;; Grau.
|
|
|
|
;; 0.05: New import format scheme: Replaced icalendar-import-prefix-*,
|
|
;; icalendar-import-ignored-properties, and
|
|
;; icalendar-import-separator with icalendar-import-format(-*).
|
|
;; icalendar-import-file and icalendar-convert-diary-to-ical
|
|
;; have an extra parameter which should prevent them from
|
|
;; erasing their target files (untested!).
|
|
;; Tested with Emacs 21.3.2
|
|
|
|
;; 0.04: Bugfix: import: double quoted param values did not work
|
|
;; Read DURATION property when importing.
|
|
;; Added parameter icalendar-duration-correction.
|
|
|
|
;; 0.03: Export takes care of european-calendar-style.
|
|
;; Tested with Emacs 21.3.2 and XEmacs 21.4.12
|
|
|
|
;; 0.02: Should work in XEmacs now. Thanks to Len Trigg for the
|
|
;; XEmacs patches!
|
|
;; Added exporting from Emacs diary to ical.
|
|
;; Some bugfixes, after testing with calendars from
|
|
;; http://icalshare.com.
|
|
;; Tested with Emacs 21.3.2 and XEmacs 21.4.12
|
|
|
|
;; 0.01: First published version. Trial version. Alpha version.
|
|
|
|
;; ======================================================================
|
|
;; To Do:
|
|
|
|
;; * Import from ical to diary:
|
|
;; + Need more properties for icalendar-import-format
|
|
;; + check vcalendar version
|
|
;; + check (unknown) elements
|
|
;; + recurring events!
|
|
;; + works for european style calendars only! Does it?
|
|
;; + alarm
|
|
;; + exceptions in recurring events
|
|
;; + the parser is too soft
|
|
;; + error log is incomplete
|
|
;; + nice to have: #include "webcal://foo.com/some-calendar.ics"
|
|
|
|
;; * Export from diary to ical
|
|
;; + diary-date, diary-float, and self-made sexp entries are not
|
|
;; understood
|
|
;; + timezones, currently all times are local!
|
|
|
|
;; * Other things
|
|
;; + clean up all those date/time parsing functions
|
|
;; + Handle todo items?
|
|
;; + Check iso 8601 for datetime and period
|
|
;; + Which chars to (un)escape?
