我有一个 vCard 文件mycontacts.vcf:
BEGIN:VCARD
N:Montana;Joe;;;
FN:Joe Montana
BDAY;value=date:1988-05-20
END:VCARD
BEGIN:VCARD
N:Smith;Joe;;;
FN:Joe Smith
BDAY;value=date:1999-07-04
END:VCARD
如何从 linux 命令行创建一个 CalDAV 文件，例如使用 awk 或一个简单的 python 脚本，这样的输出是:
BEGIN:VEVENT
SUMMARY:Joe Montana
DTSTART;VALUE=DATE:19880520
DTEND;VALUE=DATE:19880521
END:VEVENT
BEGIN:VEVENT
SUMMARY:Joe Smith
DTSTART;VALUE=DATE:19990704
DTEND;VALUE=DATE:19990705
END:VEVENT
顺便说一句，联系人是使用 pythonista 应用程序从 ipad 导出的:
import contacts
people = contacts.get_all_people()
for p in people:
print(p.vcard.decode('utf-8'))
生成的 CalDAV 将被导入 thunderbird。
使用任何 awk，您都可以将结束日期设置为当前日期:
$ cat vcf2dav.awk
BEGIN { OFS=":" }
!NF { print; next }
{
tag = val = $0
sub(/[:;].*$/,"",tag)
sub(/^[^:]+:/,"",val)
}
tag ~ /^(BEGIN|END)$/ { print tag, "VEVENT" }
tag == "FN" { print "SUMMARY", val }
tag == "BDAY" {
gsub(/-/,"",val)
print "DTSTART;VALUE=DATE", val
print "DTEND;VALUE=DATE", val
}
.
$ awk -f vcf2dav.awk mycontacts.vcf
BEGIN:VEVENT
SUMMARY:Joe Montana
DTSTART;VALUE=DATE:19880520
DTEND;VALUE=DATE:19880520
END:VEVENT
BEGIN:VEVENT
SUMMARY:Joe Smith
DTSTART;VALUE=DATE:19990704
DTEND;VALUE=DATE:19990704
END:VEVENT
但是如果你真的想要它是后一天那么你需要使用时间函数，例如使用 GNU awk 实现内置时间函数:
$ cat vcf2dav.awk
BEGIN { OFS=":" }
!NF { print; next }
{
tag = val = $0
sub(/[:;].*$/,"",tag)
sub(/^[^:]+:/,"",val)
}
tag ~ /^(BEGIN|END)$/ { print tag, "VEVENT" }
tag == "FN" { print "SUMMARY", val }
tag == "BDAY" {
begDate = val
endDate = dayAfter(begDate)
gsub(/-/,"",begDate)
print "DTSTART;VALUE=DATE", begDate
print "DTEND;VALUE=DATE", endDate
}
function dayAfter(curDate, curSecs, nxtDate) {
curSecs = mktime(gensub(/-/," ","g",curDate)" 0 0 0")
nxtDate = strftime("%Y%m%d",curSecs + 24*60*60)
return nxtDate
}
.
$ awk -f vcf2dav.awk mycontacts.vcf
BEGIN:VEVENT
SUMMARY:Joe Montana
DTSTART;VALUE=DATE:19880520
DTEND;VALUE=DATE:19880521
END:VEVENT
BEGIN:VEVENT
SUMMARY:Joe Smith
DTSTART;VALUE=DATE:19990704
DTEND;VALUE=DATE:19990705
END:VEVENT
对于其他 awk，您将更改 dayAfter() 函数以调用 UNIX date 或执行您环境中的任何其他工作以获得第二天。
