kandi X-RAY | quit Summary
This crate allows cleanly exiting a program using a custom exit code, without the drawbacks of exit. Destructors will be called as usual, and the stack will be unwound to the main function. It is always required to attach #[main] to the main function. Then, with_code can be called from almost anywhere in the program. Restrictions are noted in the documentation for that function.

QUESTION
I've stumbled upon a quite innovative functionality in editor – ability to TAB-complete symbols from CTags index, on this Asciinema video.
I wonder if there is anything like it available for Vim? I've been using many completion engines like eg. CoC, however none of them seems to offer what NeoMCEdit does. Is there such plugin for Vim?
...ANSWER
Answered 2021-Jun-15 at 21:01Basic keyword completion, :help i_ctrl-p
/:help i_ctrl-n
, already does that out of the box because of the default value of :help 'complete'
.
Alternatively, you can use your tags
files as exclusive source with :help i_ctrl-x_ctrl-]
.

ANSWER
Answered 2021-Jun-16 at 01:14The difference in behaviour can be accounted for by this behaviour, described in (for instance) the following note in ECMAScript 2022 Language Specification sect 14.3.2.1
:
NOTE: If a VariableDeclaration is nested within a with statement and the BindingIdentifier in the VariableDeclaration is the same as a property name of the binding object of the with statement's object Environment Record, then step 5 will assign value to the property instead of assigning to the VariableEnvironment binding of the Identifier.
In the first case:

are not equivalent:
- The first statement in

it rotates bycurIndex

QUESTION
Here is my underdeveloped pygame ping-pong game, but my sprites(player&opponent) ain't moving, on giving a keyboard input. And when I quit the program, it yells an error pygame.error: video system not initialized
. My pygame is the latest 1.9.6 version with all the files up-to-daee. However, I am certain that pygame.display
is generating this error, but I even tried pygame.display.init()
and that too didn't worked :(
ANSWER
Answered 2021-Jun-15 at 14:57Here, you have two different problems :
First the movement is not working because to differentiate the keys, you use event.type
to compare where it should be event.key
. Try with for example :
QUESTION
I am trying to create scatter plots of all the combinations for the columns: insulin
, sspg
, glucose
(mclust, diabetes dataset, in R) with class as the colo(u)r. By that I mean insulin with sspg, insulin with glucose and sspg with glucose.
And I would like to do that with tidyverse, purrr, mappings and pipe operations. I can't quite get it to work, since I'm relatively new to R and functional programming.
When I load the data I've got the columns: class, glucose, insulin and sspg. I also used pivot_longer
to get the columns: attr and value but I was not able to plot it and don't know how to create the combinations.
I assume that there will be an iwalk()
or map2()
function at the end and that I might have to use group_by()
and nest()
and maybe combn(., m=2)
for the combinations or something like that. But it will probably have some way simpler solution that I can not see myself.
My attempts have amounted to this:

QUESTION
Once I enter q, I get the error:
...ANSWER
Answered 2021-Jun-15 at 17:33You need to check for "q" before you use the value. You need to convert given
to float BEFORE you add it in to the sum. The statement count+1
does nothing; it computes count + 1 and throws it away. This should work.

QUESTION
I'm trying to understand how the "fetch" phase of the CPU pipeline interacts with memory.
Let's say I have these instructions:
...ANSWER
Answered 2021-Jun-15 at 16:34It varies between implementations, but generally, this is managed by the cache coherency protocol of the multiprocessor. In simplest terms, what happens is that when CPU1 writes to a memory location, that location will be invalidated in every other cache in the system. So that write will invalidate the line in CPU2's instruction cache as well as any (partially) decoded instructions in CPU2's uop cache (if it has such a thing). So when CPU2 goes to fetch/execute the next instruction, all those caches will miss and it will stall while things are refetched. Depending on the cache coherency protocol, that may involve waiting for the write to get to memory, or may fetch the modified data directly from CPU1's dcache, or things might go via some shared cache.
QUESTION
I have a generator object, that loads quite big amount of data and hogs the I/O of the system. The data is too big to fit into memory all at once, hence the use of generator. And I have a consumer that all of the CPU to process the data yielded by generator. It does not consume much of other resources. Is it possible to interleave these tasks using threads?
For example I'd guess it is possible to run the simplified code below in 11 seconds.
...ANSWER
Answered 2021-Jun-15 at 16:02Send your data to separate processes. I used concurrent.futures because I like the simple interface.
This runs in about 11 seconds on my computer.
