Hello,

If I have a test file

----------------------------------------------------------------------

* test 1

<2023-01-05 Thu 19:00-19:20>

----------------------------------------------------------------------


and then convert to an .ics file using C-c C-e c f

I get the attached test.ics file, but copied here too:

The lines from BEGIN:VEVENT to CATEGORIES:test inclusive have CR (^M) as well

https://icalendar.org/validator.html gives me the error

> Reference: RFC 5545 3.1. Content Lines

Nicolas (cc'ed) has confirmed that it seems to be a problem.  Before I
work slowly on a suggested patch, does anyone have an idea on the best
way forward?  Is it possible to encode the file as "DOS" ,using
something like set-buffer-file-coding-system?  SOme lines do however
have \r and \n see e.g. org-icalendar-fold-string which inserts both \r
and \n




Best wishes, Stephen

Hello,

just to confirm. The exporter is inconsistent in adding
which kind of EOL sequence.

Sorry for the late reply.

Do I understand correctly that all the ical lines must use \r\n? [1]

If so, we can simply wrap the export output into
`org-icalendar-fold-string' in `org-icalendar-template'. Does it make
sense?

Following up here that I have pushed a fix for the EOL issue in
ox-icalendar:

https://list.orgmode.org/87355ikzwk.fsf@localhost/T/#m180c100587d3d88ab5787942271a546b51891996

Thanks for copying me in on this.

There is a related issue about EOLs, not just \r\n -- each line should
be a maximum of 75 characters; this is handled by 
org-icalendar-fold-string 

I'll check out the revised code to see if this is still an issue.

Stephen

May you please provide a link to the iCalendar spec document section
describing this requirement?

Since VEVENT and VTODO are wrapped in `org-icalendar-fold-string', I
think the only place this error may occur is in the preamble created by
`org-icalendar--vcalendar', e.g. in PRODID, X-WR-CALDESC, etc.

The fix is to move the call to `org-icalendar-fold-string' out of
org-icalendar--vevent/vtodo, and instead put it in
`org-icalendar--vcalendar'. Then the line folding will apply to the
whole VCALENDAR instead of just the VTODO and VEVENT. An earlier version
of my CRLF patch actually did something like this.

I can push such a fix over the weekend. Let me know if you'd rather I
send the patch for review here first.

yes, that's it.   There is also this validator that can check files
against the spec:  https://icalendar.org/validator.html
