Implement day of week cycle '#' about croncal HOT 10 CLOSED

Aaaah, ok, just noticed that the default end is 1 day, sorry.

First tests done, seems promising !!

Agreed. I should find out how that plays together with the /n modifier, but I'll check it out.

I don't have access to a system that supports this syntax, could you provide an example of the semantics (if it's legal at all) of an expression like 1,2,3#2? Does it mean "the second monday and the second tuesday and the second wednedsay of the month" or does it mean "all mondays, all tuesdays and the second wednesday of the month"? What about 1-3#2? Also, how do you express "second and third monday of the month" (if it can be expressed)? Like so: 1#2,3 or like 1#2,1#3 ?

This cron syntax is for example used in Gitlab which uses fugit (https://github.com/floraison/fugit) to parse the cron syntax.

Those two links https://github.com/floraison/fugit#the-first-monday-of-the-month and https://github.com/floraison/fugit#the-hash-extension, explain the why and the how.

To reply to your questions:

1,2,3#2: All the Mondays, all the Tuesdays and the second Wednesday of each month
1-3#2: This syntax is not valid. You have to use instead 1#2,2#2,3#2
1#2,1#3: This will express the second and third Monday of each month
1#2,3: This will express the second Monday of each month and every Wednesday

So in resume, the hash can only be used after a day of the week. Hash does not support a range. If we want to specify several days, hash included, you have to use the usual coma separated list.

Excellent! Let me see what I can come up with.

Should be working now. Please try it and report any issues. Thanks!

Whoaaa, that was quick. A big thanks !

So now testing the script, I notice that I am unable to display the calendar. Tried on Ubuntu 20.04 and CentOS 7, but nevermind how I am testing it, this command don't display anything:

$ echo "30 0 * * 3 job1" | ./croncal.pl
$ 

If I try with a wrong formatted entry to stdin:

$ echo "dumb test" | ./croncal.pl 
Warning, skipping unrecognized crontab line 1: dumb test

Can see the error, so it seems that this is a print issue ?

Is it only me ? Am I doing something wrong here ?

from croncal.

Well, 3 as day of week means wednesday, the program by default uses now / now + 1 day as time interval, so since there's no wednesday in that time range, nothing is printed. If you expand the interval to include a wednesday, it works:

$ echo "30 0 * * 3 job1" | ./croncal.pl -s '2022-02-13 00:00' -e '2022-02-20 23:59'
2022-02-16 00:30|job1

Closing as I'm assuming that it's working fine for you. Feel free to reopen or add further comments if not.

Sorry for the late reply. I have implemented this new version, and so far so good, working like a charm it seems.

Thanks for your support !
