Answered 2021-Jun-16 at 02:44In the Map, set the value not to the cumulative total time for the employee so far, but to a whole employee object that contains the total time inside it. Spread the first object found so as not to mutate the input.
QUESTION
I want to have my reference counted C++ object also managed in Lua callbacks: when it is held by a Lua variable, increase its refcount; and when the Lua variable is destroyed, release one refcount. It seems the releasing side can be automatically performed by __gc
meta-method, but how to implement the increasing side?
Is it proper&enough to just increase refcount every time before adding the object to Lua stack?
Or maybe I should new a smart pointer object, use it everywhere in Lua C function, then delete it in __gc
meta-method? This seems ugly as if something wrong with the Lua execution and the __gc
is not called, the newed smart pointer object will be leaked, and the refcounted object it is referring would have leak one count.
In Perl that I'm more familiar with, this can be achieved by increase refcount at OUTPUT
section of XS Map, and decrease refcount at destroyer.
ANSWER
Answered 2021-Jun-10 at 19:23I assume you have implemented two Lua functions in C: inc_ref_count(obj)
and dec_ref_count(obj)
QUESTION
I see that jq
can calculate addition as simply as jq 'map(.duration) | add'
but I've got a more complex command and I can't figure out how to perform this add
at the end of it.
I'm starting with data like this:
...ANSWER
Answered 2021-Jun-15 at 22:54If any of your output is going to be raw, you need to pass -r
; it'll just be ignored for data items that aren't strings.
Anyhow -- if you write (expr1, expr2)
, then your input will be passed through both expressions. Thus:
QUESTION
I have this code which prints multiple tables
...ANSWER
Answered 2021-Jun-15 at 20:59So, this is a good opportunity to use purrr::map
. You are half way there by applying code to one dataframe.
You can take the code that you have written above and put it into a function.
QUESTION
so I'm struggling with these things:
I have method that returns istream input and takes istream input as a parameter, sends values to vector and stores them in it. Now, when I've entered 1 value, I'm trying to make a check if vector already contains that value, here is my code to understand it better:
...ANSWER
Answered 2021-Jun-15 at 20:14first of all, you can check count of std::vector to see if given key exists
QUESTION
I am working in react application and founded this stubborn thing. This is my state in react to which i am working on
...ANSWER
Answered 2021-Jun-15 at 20:51You seem to be confusing useState
with the class component's state.
Running setState({ testInfo: testInfoArray });
sets the entire state to { testInfo: testInfoArray }
, removing state.selectedParagraph
entirely, causing it to be undefined
.
You'll want to use useState
multiple times, like this:
QUESTION
I'm trying to implement a Select component using reactjs material ui and typescript.
However, I am getting the following typing error:
...ANSWER
Answered 2021-Jun-15 at 20:40From what it looks like, options is actually an array of objects rather than just an object. So all you would need to do is map over the options variable. You are currently using Object.keys which is what you use if you are wanting to iterate over the keys in an object.

QUESTION
I want to create components dynamically with custom Refs , and I want to use those refs and use with functionalities like measure() etc.
I created following code
...ANSWER
Answered 2021-Jun-15 at 19:50- Yes, React refs need to be forwarded when using functional components.
- You can't use the
useRef
hook within the loop.
Fix creating the refs. Use a React ref to hold an array of created refs, and pass them by mapped index.
