QUESTION
I have a navbar that is rendered in every route while the route changes on click.
./components/navbar.jsx
...ANSWER
Answered 2022-Feb-09 at 23:28You are rendering the navbar outside the routing context. The Router
isn't aware of what routes the links are attempting to link to that it is managing. The reason routing works when directly navigating to "/experiences"
is because the Router
is aware of the URL when the app mounts.

QUESTION
I've been working in Linux for the last 12 years, worked with Windows and command lines before that and have had to recently resurrect those batch file skills for a little easy to use / edit utility. However, I'm having some issues in finding out how to build up a string variable with newline characters (the equivalent of Linux's echo -e "Line1\nLine2"
)
Basically my utility asks three questions of a user and checks the validity of the inputs. Each input has a slightly different "error message" if the validity fails. I then have a check to see if the errMsg
variable contains anything and if it does, it lists the collated error messages from the 3 validity checks. This all works perfectly with the exception of the error message is on one line and I'd like to put each error on it's own line. I then "merely" add newlines to the string ... and that's the crux of this question.
I've used this link as a reference point and with a basic string, the new lines appear as expected. However, when I use a variable, the new lines don't appear and I was hoping someone could explain to me why.
I have the following code snippet
...ANSWER
Answered 2022-Jan-21 at 22:37To create a new line variable is a good start. But you should use it in a different way.
Percent expansion doesn't work quite well with newlines in variables, it can be done, but it's quite complex.
But delayed expansion flawlessly works with any characters
QUESTION
I am new to NER
and Spacy
. Trying to figure out what, if any, text cleaning needs to be done. Seems like some examples I've found trim the leading and trailing whitespace and then muck with the start/stop indexes. I saw one example where the guy did a bunch of cleaning and his accuracy was really bad because all the indexes were messed up.
Just to clarify, the dataset was annotated with DataTurks, so you get json like this:
...ANSWER
Answered 2021-Dec-28 at 05:19First, spaCy does no transformation of the input - it takes it literally as-is and preserves the format. So you don't lose any information when you provide text to spaCy.
That said, input to spaCy with the pretrained pipelines will work best if it is in natural sentences with no weird punctuation, like a newspaper article, because that's what spaCy's training data looks like.
To that end, you should remove meaningless white space (like newlines, leading and trailing spaces) or formatting characters (maybe a line of ----
?), but that's about all the cleanup you have to do. The spaCy training data won't have bullets, so they might get some weird results, but I would leave them in to start. (Also, bullets are obviously printable characters - maybe you mean non-ASCII?)
I have no idea what you mean by "muck with the indexes", but for some older NLP methods it was common to do more extensive preprocessing, like removing stop words and lowercasing everything. Doing that will make things worse with spaCy because it uses the information you are removing for clues, just like a human reader would.
Note that you can train your own models, in which case they'll learn about the kind of text you show them. In that case you can get rid of preprocessing entirely, though for actually meaningless things like newlines / leading and following spaces you might as well remove them anyway.
To address your new info briefly...
Yes, character indexes for NER labels must be updated if you do preprocessing. If they aren't updated they aren't usable.
It looks like you're trying to extract "skills" from a resume. That has many bullet point lists. The spaCy training data is newspaper articles, which don't contain any lists like that, so it's hard to say what the right thing to do is. I don't think the bullets matter much, but you can try removing or not removing them.
What about stuff like lowercasing, stop words, lemmatizing, etc?
I already addressed this, but do not do this. This was historically common practice for NLP models, but for modern neural models, including spaCy, it is actively unhelpful.

I need to write a function (f
) that accepts a std::function
(g
) with a generic callback parameter. In the function f
, some additional code should be executed when the callback is called. I would therefore need to create a lambda with a signature depending on the generic callback parameter. My template skills fails me here.
So basically, in the snippet below, both g1
and g2
should be possible to use as input to f

QUESTION
I have this powershell scrip where I want to copy files from our production server to our test server, and only have it copy files which are newer or changed. The script itself has many more functions but this copying is one of those. I'm using the following XCopy command for that:
...ANSWER
Answered 2021-Oct-25 at 19:15This is a side-effect of using the sub-expression operator $()
here (note you would get the same effect using the group-expression operator ()
as well). The reason this happens is because $()
and ()
function like parentheses in mathematics, and order of operations (technically order of precedence in computing) dictates that inner expressions be worked out before outer expressions. So anything inside the parentheses must complete first before it can be processed by the outer code.
In your case here, the "outer code" is what displays information to the console, hence, why the inner command has to complete before it gets displayed.
If you don't need to evaluate $output
later on, the simplest and most performant approach is to pipe your command output directly to Out-Host
instead (you probably also want to redirect error output as well):
QUESTION
I'm working to advance my regex skills in python, and I've come across an interesting problem. Let's say that I'm trying to match valid credit card numbers , and on of the requirments is that it cannon have 4 or more consecutive digits. 1234-5678-9101-1213 is fine, but 1233-3345-6789-1011 is not. I currently have a regex that works for when I don't have dashes, but I want it to work in both cases, or at least in a way i can use the |
to have it match on either one. Here is what I have for consecutive digits so far:
validNoConsecutive = re.compile(r'(?!([0-9])\1{4,})')
I know I could do some sort of replace '-'
with ''
, but in an effort to make my code more versatile, it would be easier as just a regex. Here is the function for more context:
ANSWER
Answered 2021-Oct-24 at 21:49You can add the (?!.*(\d)(?:-*\1){3})
negative lookahead after ^
(start of string) to add the restriction.
The ^(?!.*(\d)(?:-*\1){3})
pattern matches
^
- start of string(?!.*(\d)(?:-*\1){3})
- a negative lookahead that fails the match if, immediately to the right of the current location, there is.*
- any zero or more chars other than line break chars as many as possible(\d)
- Group 1: one digit(?:-*\1){3}
- three occurrences of zero or more-
chars followed with the same digit as captured in Group 1 (as\1
is an inline backreference to Group 1 value).
See the regex demo.
If you want to combine this pattern with others, just put the lookahead right after ^
(and in case you have other patterns before with capturing groups, you will need to adjust the \1
backreference). E.g. combining it with your second regex, validLength = re.compile(r'^[0-9]{16}$|^[0-9]{4}-[0-9]{4}-[0-9]{4}-[0-9]{4}$')
, it will look like
