kandi X-RAY | tre Summary

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

TRE is a lightweight, robust, and efficient POSIX compliant regexp matching library with some exciting features such as approximate (fuzzy) matching. The matching algorithm used in TRE uses linear worst-case time in the length of the text being searched, and quadratic worst-case time in the length of the used regular expression. In other words, the time complexity of the algorithm is O(M^2N), where M is the length of the regular expression and N is the length of the text. The used space is also quadratic on the length of the regex, but does not depend on the searched string. This quadratic behaviour occurs only on pathological cases which are probably very rare in practice.

Excel: object variable or with block not set

Anyone know why the below code halts on range_i.Copy with error? This is related to this question but you don't need to review that question to know the answer to this one I don't think! :-) Thanks

Although you may have figured this out already, here's for the sake of having an answer on a QA site...

As noted by Raymond in the comments: "This error can occur if range_i is nothing..." - And that is exactly why your error occurs.

range_i occurs six times in your code - three key points:

You Set it to Nothing.
The If Not range_i Is Nothing Then statement
Your problem line.

Here are some key learnings from these points;

You Set your variable to Nothing but you don't declare it!

By having range_i as an undeclared variable, it's implicitly declared as a Variant data type - not a range.

You should include Dim range_ i As Range as part of your variable declarations - this will help avoid unexpected errors or issues like assigning something other than a range to the variable (Such as a value of the range rather than the range itself).

If Not range_i Is Nothing Then is the same as saying If range_i is Something Then which I don't think is your intention?

You are trying to copy some range intended to be set to a Variant variable that, as outlined above; you have never set because you first set it to Nothing, then prior to setting it to something you check if it's Not Nothing (Something) which it isn't.

Due to these issues you inevitably get the Object variable or With block variable not set Error.

You can read the documentation for this error here.

You get the error because you are using a lookbehind, (?<=\|), but did not use the perl=TRUE argument to enable the PCRE regex engine that supports lookbehinds. The default TRE regex engine does not support lookarounds.

You need to match the whole string:

Your regex does not work due to the trailing (\s|) pattern that consumes a whitespace and prevents consecutive matches.

You can use a PCRE regex like

You can remove the addition of the aesthetics to the legend from any geom (at least, I think any geom) by setting the boolean show.legend within that geom call. So, show.legend = FALSE seems to do the trick for me:

As Deceze has commented, if the data is corrupted at source there is no guarantee that you can undo the corruption. However, using the data you provided we can make some progress.

Firstly, the vast majority of the strings in your list can be fixed by encoding as latin-1 and then decoding as UTF-8.
