kandi X-RAY | pcre2 Summary

pcre2 is a C library typically used in Utilities, Regex applications. pcre2 has no bugs, it has no vulnerabilities and it has low support. However pcre2 has a Non-SPDX License. You can download it from GitHub.

The PCRE2 library is a set of C functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5. PCRE2 has its own native API, as well as a set of wrapper functions that correspond to the POSIX regular expression API. The PCRE2 library is free, even for building proprietary software. It comes in three forms, for processing 8-bit, 16-bit, or 32-bit code units, in either literal or UTF encoding. PCRE2 was first released in 2015 to replace the API in the original PCRE library, which is now obsolete and no longer maintained. As well as a more flexible API, the code of PCRE2 has been much improved since the fork.

QUESTION

REGEX for matching number with two and three numbered patterns together

Asked 2022-Jan-17 at 10:25

I have an array of 5 numbers, I'd like to match as long as there are three of the same number and two of the same different number in the array, placement does not matter. Number sequences can be any random string of 5 numbers between 1 - 5. Examples of matches would be: 33322 24422 52225 44111 54545 *basically any grouping of 2 and 3 of the same numbers needs to match.

Best I've come up with so far: ^([0-9])\1{2}|([0-9])\1{1}$

I am not so good with regex, any help would be greatly appreciated.

A simple solution would be to convert all characters to lowercase, replace any character that isn't a-z, 0-9, or a space with a space character, and then replace multiple space characters with a single space character.

I am trying to understand the difference between the two and when I would want to use one over the other?

...

ANSWER

Answered 2021-Nov-16 at 14:57

Pattern.asPredicate will return true if any part of the input string matches the Regular expression. You should use this method if you're testing some larger body of text for a certain pattern. For example, to test whether a comment from a user contains a hyperlink.
Pattern.asMatchPredicate will return true if the entire input string matches the Regular expression. You should use this method if you're testing the entire input for a certain pattern. For example, to validate the phone number of a user in their profile.

Pattern.asPredicate internally uses Matcher.find(), while Pattern.asMatchPrediate internally uses Matcher.matches(). So the difference between the two boils down to the difference between these two methods from the Matcher class.

Below are some examples to showcase the difference. You can copy & paste below code in an online Java sandbox like https://www.compilejava.net/ to play around with it yourself.

For example, in the below string I want to replace the single occurrence of 1 with 2.

ANSWER

Answered 2021-Oct-04 at 08:47

Here is a solution that assumes that there are no nested tags, that all tags open and close in the part. Also, this assumes that all characters from the sentence are in parts. For this last assumption, I had to add the . after it has to be in the second expected part. I also had to remove newline characters from the sentence but I think it was because of the copy/paste. This solution will loop through all characters and store two parallel buffers : one with the tags, one without. We will use the second one to compare with the parts, and use the first one to generate the output.
