24.4.50; [PATCH] diary Chinese support |
|
Date: |
Sat, 03 May 2014 12:25:49 +0800 |
The patch adds support for Chinese dates in diary, in which the cycle
and year are concatenated as cycleyear i.e. cycle 78 and year 31 is
represented as 7831. The following commands are available in the
calendar window:
KEY COMMAND

`i C a' diary-chinese-insert-anniversary-entry
`i C d' diary-chinese-insert-entry
`i C m' diary-chinese-insert-monthly-entry
`i C y' diary-chinese-insert-yearly-entry

Thanks for the comments. Fixed accordingly and installed.
BTW, in diary-chinese-list-entries I also changed `prefaced' to
`prefixed'. The doc-string is adopted from similar entries in other
non-grepgorian calendars which still use `prefaced'. Any comments?
