QUESTION

Create a DateTimeFormater with an Optional Section at Beginning

Asked 2021-Jun-15 at 19:54

I have timecodes with this structure hh:mm:ss.SSS for which i have a own Class, implementing the Temporal Interface. It has the custom Field TimecodeHour Field allowing values greater than 23 for hour. I want to parse with DateTimeFormatter. The hour value is optional (can be omitted, and hours can be greater than 24); as RegEx (\d*\d\d:)?\d\d:\d\d.\d\d\d

For the purpose of this Question my custom Field can be replaced with the normal HOUR_OF_DAY Field.

ANSWER

Answered 2021-Jun-11 at 11:06

I think fundamentally the problem is that it gets stuck going down the wrong path. It sees a field of length 2, which we know is the minutes but it believes is the hours. Once it believes the optional section is present, when we know it's not, the whole thing is destined to fail.

This is provable by changing the minimum hour length to 3.

QUESTION

Preg_match is "ignoring" a capture group delimiter

Asked 2021-Jun-15 at 17:46

We have thousands of structured filenames stored in our database, and unfortunately many hundreds have been manually altered to names that do not follow our naming convention. Using regex, I'm trying to match the correct file names in order to identify all the misnamed ones. The files are all relative to a meeting agenda, and use the date, meeting type, Agenda Item#, and description in the name.

Our naming convention is yyyymmdd_aa[_bbb]_ccccc.pdf where:

yyyymmdd is a date (and may optionally use underscores such as yyyy_mm_dd)
aa is a 2-3 character Meeting Type code
bbb is an optional Agenda Item
ccccc is a freeform variable length description of the file (alphanumeric only)

Example filenames:

Answered 2021-Jun-15 at 17:46

The optional identifier ? is for the last thing, either a characters or group. So the expression ([a-z0-9]{1,3})_? makes the underscore optional, but not the preceding group. The solution is to move the underscore into the parenthesis.

There is a general format that can be followed. Although in certain scenarios, it becomes necessary to break away from the traditional style, your situation seems to be fairly basic. Here is a PEP convention guide for docstrings in Python:

The documentation for the azurerm_web_application_firewall_policy resource is out of date but http_listener_ids and path_based_rule_ids are read only now (as of v2.55.0) so you can't set them and can only read them as an attribute of the resource.

At this point you can run bundle exec jekyll serve
