generouslabs / md2carddav Goto Github PK

From today's changes, I introduced a bug. The new comparison code chokes if a new type of entry (like an email) is added.

That's the relevant code.

There's also a logic bug in that only 1 of the 2 vcards are considered, so if the other vcard had extra keys, they would be ignored.

There's a formatting issue.

Our format looks like Foo, Bar while FastMail's format is Foo\\, Bar.

Specs:

• IETF vCard Format Specification
• IETF CardDAV Specification
• IETF Document Search "carddav"
• 42 Open Source CalDAV Software Projects

Projects:

• Org-Mode examples of using CardDAV
  • org-caldav
• Similar note-taking apps
  • Joplin
    • Says it supports "WebDAV"
    • Maybe this code can be adapted?
• Javascript-based
  • tsdav
    • Supports WEBDAV, CALDAV, CARDDAV
  • node-vcf
    • vCard parser, create new vCard
  • cdav-library
    • Used by NextCloud
    • CalDAV AND CardDAV client library for JS
• Python-based
  • khard
    • Python-based
    • Meant for use in terminal application
    • Does not support synching with Android or iOS(!?)
• Java-based
  • ez-vcard
  • carlDAV
• CardDAV Servers
  • sabre/dav
    • WebDAV framework for PHP
    • Used to create WebDAV, CalDAV and CardDAV servers
  • radicale
    -Small but powerful CalDAV (calendars, to-do lists) and CardDAV (contacts) server
• Unknown
  • DecSync
    • I don't know if this helps
    • Maybe libdecsync helps?

Issues with vCard spec:

• The sad story of the vCard format and its lack of interoperability
  • 11/15/2012
  • vCard "...does not support social networking addresses yet."
• Another andecdote about vCard being buggy

Questions

• I'm unclear on the infrastructure:
  • Will this project include a local CardDAV server?
  • What will authentication to remote CardDAV servers (iCloud. Android, etc.) look like?

Ideas

• This project reminds me of the Insidious Big Brother Database (contact manager!) in Emacs

FastMail has started returning UIDs like:

UID;VALUE=uri:xxxx

I believe it used to be like:

UID:xxxx

This means that the getUidFromVcard() function returns undefined instead of the UID.
