QUESTION
My $GOPATH is /home/shambhav/code_mis/golang
(current gopath), but long ago when I was setting up GO, I messed it up and GOPATH was /home/shambhav/home/shambhav/code_mis/golang
(previous gopath). I noticed this and deleted the contents of /home/shambhav/home/shambhav/code_mis/golang
and the directory itself and set GOPATH to the correct place.
Visual Studio Code seems to have stored /home/shambhav/home/shambhav/code_mis/golang
as my GOPATH. And it isn't changing even after I changed my GOPATH. VSC obviously can't find my imports and things like gocode, goimports, golps etc in /home/shambhav/home/shambhav/code_mis/golang
, VSC is kinda useless now. And also when I let VSC to download gocode, golps, etc to see what would happen, it remade /home/shambhav/home/shambhav/code_mis/golang` and put the files there.
I'm not going to switch my GOPATH because the directory is so weird, I will be made fun of if someone sees it, the only option is to update the GOPATH.
Some clarification, the Go compiler knows my actual GOPATH, it's just VSC not updating it.
So,
Long ago: GOPATH = home/shambhav/home/shambhav/code_mis/golang
VSC stored the Long ago GOPATH.
Now: GOPATH = home/shambhav/code_mis/golang
But VSC still thinks that the long ago GOPATH is still the real GOPAH and it is causing problems.
...ANSWER
Answered 2021-May-09 at 08:34You can change the GOPATH for only the VS Code Go extension tools by specifying the go.toolsGopath
property in settings.json
So, in settings.json
that would be,

I'm new in dart, I'm trying to read information from a txt file and use the data to create objects from a class (in this case about pokemon), but when I run my program in the terminal it doesn't prints the correct information, and when I run the program in vscode (whit the dart extension, the "run" button) it prints in the debug console the correct information. What is the problem?
When I run the program in vscode I get in my print method (printP) this (which is what I want)

...ANSWER
Answered 2020-Aug-01 at 16:26Your code are dependent on the newline format of your txt file. I will recommend you are using the LineSplitter
class from dart:convert
to split your lines.
The problem is that Windows newlines contains both '\n'
and '\r'
but you are only removing the '\n'
part. '\r'
are essential meaning the terminal should set the cursor back to the beginning of the line.
You can read this like a typewriter where you first move the head back and set move the paper to the next line. And can read a lot more about is topic here: https://en.wikipedia.org/wiki/Newline
The purpose of the LineSplitter
class is to abstract all of this logic and get some behavior which will work on all platforms.
So import dart:convert
and change this line:
QUESTION
I broke my original JSON file up into two different JSON files, but now I can't decode the second one. I've run it through multiple validators and it seems to be valid JSON, and I tried making certain properties optional, but to no avail.
Here's the extension I'm using to decode, which works for the first file, but crashes for the second one with the message "Thread 1: Fatal error: Failed to decode justiceforvictims.json from bundle."
...ANSWER
Answered 2020-Jun-16 at 02:48The issue is your top level json type is an object of type petitionLabel
rather than Array [petitionLabel]
. So it's not issue of SwiftUI.
So you would need to change

Answered 2020-Mar-02 at 20:57JObject.SelectToken
expects a path to a particular token. It doesn't traverse the object to find anything with a matching name.
Looking at the object, the root object seems to have a single property with the key being the app id. That in turn has two properties, success
and data
, with data
containing the actual info you seek.
The following works for me:

Answered 2018-Nov-11 at 09:38The color which is use for drawing characters by glutBitmapCharacter
is set by glRasterPos

QUESTION
I'm creating a page to describe each class of my RPG game in sections (mage, bard, assassin, etc). In each section I have an image and a description of the character, and for each section I want to give different wallpapers with a white layer with 0.5 opacity over the wallpaper but I don't know how.
I tried adding different div tags for each section with different wallpapers but every new wallpaper covers all the page.
I'm going to show the code so far and you can see the results here and here
...ANSWER
Answered 2019-Mar-27 at 17:31Set background-image
on your section containers, and size and position as you like. I am applying the overlay as a pseudo element (:before
) on that container and using absolute positioning and width/height 100% to cover the area, and an rgba
value for the color so I can control the opacity (0.5
in this case). z-index
and position:relative
used to enforce the content of the div to be on top of the background overlay.
Use additional different classes to add different backgrounds to the different sections.
QUESTION
I want to create 3 checkboxes that when checked will periodically click on a button (each).
The left and middle button are the same case, only with different aesthetics. Like this:
...ANSWER
Answered 2019-Feb-04 at 20:29So, you are trying to activate those checkboxes to fire those timers when checked and cancel the timers when unchecked?
If so:
- Add a listener for the
change
event (so that both keyboard and mouse work). - Store a reference to the timers so that they can be deleted.
- Use one event listener for "DRY" maintainable code. Add a
data-
attribute so the code knows which target goes with which checkbox. - Don't add nodes like that!
This code works:
(Pro tip: After clicking the run snippet button but before checking a checkbox, hit the "Full page" link to the right of said button.)
