Golang: Create nested from linear array bassed on id and parent id

Asked 2022-Mar-11 at 10:41

I have a data linear of name such as:

name: One, Id: 1, ParentId: 0
name: One-One, Id: 2, ParentId: 1
name: One-One-One, Id: 3, ParentId: 2
name: One-One-Two, Id: 4, ParentId: 2

For example this data, I get from the database, but I think to test the logic I make the dummy data to struct. I think I make a temporary index, for data recursively. I set if data does not exist in a map, and I get index if data has to append for before slice. But, I think in function recursive (i show it bellow), it doesn't work (data not append). Why? is there any wrong algorithm logic?

And what is the right solution for my result is

Slice is not an array

appending to slice in function doesn't increase length and capacity of original slice.

How to setup VSCode for golang/go cmd module?

Asked 2021-Oct-15 at 03:25

It works well for std module (golang/go root directory) on VSC. However it doesn't work on cmd module (opened from src/cmd directory). There were no code navigation, symbol search, and even any problems/errors reported.

Version info:

vscode: 1.61.0 vscode-go: v0.28.1

Open VSC from $WORKSPACE/go. Follow the instruction of https://github.com/golang/tools/blob/master/gopls/doc/advanced.md#working-on-the-go-source-distribution as @hana mentioned:

Compile the Go binary. Change working directory to $WORKSPACE/go/src and run ./make.bash (or ./make.bat for Windows cmd). It will generate the $WORKSPACE/go/bin directory.
Set "go.goroot" to "${workspaceFolder}" and install all Go tools required.

That looks like a package.json error. Make sure you have a package.json created.

Use the command npm init, and fill out the needed information, to have it automatically create everything use npm init -y (and then make sure to install all of your npm packages)

Unable to compare byte slices

Asked 2021-Jun-18 at 05:00

I am trying to write a unit test case, where I'm using reflect.DeepEqual to compare computed and expected results. One of the entries in the struct is a byte slice and DeepEqual keeps on failing it.

How to initialize nil slices in a struct using reflect

Asked 2020-Nov-06 at 11:11

For any given struct, I want to loop over its fields and set any nil slices to an empty slice. However, slices are unaddressable and hence not settable. How can I set the values of any nil slices?

Example: https://goplay.space/#iV6OHkYVTru

ANSWER

Answered 2020-Nov-06 at 11:09

You can't update / modify foo in initNilSlices() if you pass foo because that will be a copy, and you could only modify the copy (and not the original value).

This is what the error message "hints":

QUESTION

When trying to implement an io.Reader that uses channels I get a fatal error

Asked 2020-Oct-10 at 02:41

I apologise for the very simple question, just having some trouble wrapping my head around how we implement io.Reader.

My final use case is that I am consuming an endless stream that can send data at any time. To simulate this I have created an emitter that implements io.Reader and io.Writer.

I listen to the reader using a bufio.Scanner concurrently, while sending values to any listener from main.

Playground: https://goplay.space/#eJfe0HyfYrL

ANSWER

Answered 2020-Oct-10 at 02:41

The goroutine blocks in emitter.Read on receive from <-em.ch. The main goroutine blocks on wg.Wait. Deadlock!

Fix by adding a Close() method to emitter to close em.ch. Return io.EOF in emitter.Read when the channel is closed. Close the emitter when done sending data.

There are other issues with the emitter. Instead of fixing emitter, use io.Pipe to connect the writer to the reader:

You are very close to getting it! First, since you already create the hashMap in main() you don't need to create again in from(). Just delete line 14 and change the signature of from() like this:
