Assuming the question is serious:

the regex matches

^ (start of input)
What looks like you intended as one or more of the "CJK Unified Ideographs" block (though only from the 1.0.1 Unicode standard).

However, this is not what is parsed. (Instead, indeed it parses as regular hex escapes which does match 1).

The docs tell me that you might have wanted \x{dddd} but that requires Unicode support.

Digging in more docs tell me that

There are two ways to use Boost.Regex with Unicode strings:
Rely on wchar_t
(lists a bunch of limitations and conditions)
Use a Unicode Aware Regular Expression Type.

May I suggest the latter
one or more numerical digits (according to the locale's character classicification)
(#?) might have been intended as a comment ((?#)) but as spelled optionally matches a single # character
followed by $ (end of input)

That's not in your input, so it shouldn't match.

Off Topic?

Besides, since this is a fully anchored pattern (^$) it would only make sense with regex_match, not regex_search.

The while loop is a weird idea, because the input never changes, so neither will the search result. If there's a match, the loop always breaks. Your while amounts to a more confusing if statement.

The Fix

Here's a program that codes three switchable approaches with three different regexes.

The approaches are BOOST_SIMPLE, BOOST_UNICODE and STANDARD_LIB.

The first regex is yours, the second with \x{XXXX} escapes instead and the third is using the named character class \p{InCJK_Unified_Ideographs}.

The result is:

Boost + Unicode approach works correctly (except with your faulty regex)
Standard library (on my GCC 10 install) as well as Boost Simple appear to accept the named character class. I'm doubtful that it actually matches correctly, so I guess it will just fail to match.

QUESTION

Word VBA Search and Replace Running very Slow, Consuming to many resources

Asked 2020-Mar-02 at 15:49

I have an 800+ page document created by a modelling program. This document consists primarily of a series numbered sentences (not numbered lists). There can be 10,000 numbered lines which will be converted into 5000-7000 numbered lists of varying lengths.

The VBA for Word script (see below) searches for the first numbered paragraph following and un-numbered paragraph, then looks for the last numbered paragraph before an un-numbered paragraph, then converts the range to a numbered list. This sequence is repeated till the end of the document.

The procedure works as expected. The problem is, it consumes 65-95% of CPU, most of the physical memory and takes 5-15 hours to run.

Any thoughts on improving the performance by at least a magnitude (well at least half or quarter the time) would be greatly appreciated.

This may be one solution. You may have to tune the regex pattern depending on your document. Performance seems reasonable:

Using Xpressive

You should make the action a lazy actor. Your Data constructor call isn't.

Only one of two practically identical JavaScript functions being run

Asked 2017-May-29 at 12:54

I'm probably being very stupid here...

I have two JavaScript functions that are practically identical except each one refers to a different element.

The idea is to show and hide a toast/notification when the document loads.

For one element (errorexplanationcontainer), it works... For the other (alert), it doesn't...

Install sregex

Gnu make and gcc are required. (On operating systems like FreeBSD and Solaris, you should type gmake instead of make here.). It will build libsregex.so (or libsregex.dylib on Mac OS X), libsregex.a, and the command-line utility sregex-cli and install them into the prefix /usr/local/ by default.
