As explained in microsoft/TypeScript#2548, the following code is not correct when useDefineForClassFields: false, which is the default for targets before ES2021.

const x = 1
class C {
    p = x
    constructor(x: string) { }
}

However, when useDefineForClassFields: true, there shouldn't be an error here.

Expected: No error 2301 on `private p =

Whiskers' regex looks for <..> as opposed to tokenizing the input, so it is not able to detect truncated/mistyped input.

For example it can't detect that <!b is not terminated in<?b> X <!b Y </b>.

With some heuristics it could be improved: match for <?, <! and </ and only allow identifiers which are terminated with >, otherwise it is invalid.

I'm Writing a ThemeColor Plugin, use Visitor.

In fn:visitColor , node.parent sometimes is null (box-shadow:0 0 0 1px #999 inset). I can't find the parent Declaration Node of Color Node.
so I want to [less.js/lib/less/visitors/visitor.js Visitor.prototype.visit](https://github.com/less/less.js/blob/0e268598c8327b9e8d36d9bb2edfde95d8d787be/packages/less/src/less/visitors/visitor.js

I can't find any documentation or thorough tests of the path substitution performed by compiler/options/pathSubs.

From looking at the code, these are the substitutions:

• $nim: global nim prefix directory path
• $lib: stdlib directory path
• $home: user's home directory path
• $config: I think this is the directory path to the either the nimscript calling
  `compiler/options/path

we added linux mmap in RustPython/RustPython#3755

adding initializer and a few tuning will let windows also run the module.

안녕하세요

자료 보면서 공부하다가 counting sort 코드가 이상한 부분이 있어서 수정했습니다

1. 과정 3에서 누적합을 만들어줄 때 arr.length -> counting.length
2. 과정 4에서 다시 sorted_arr에 넣어줄 때 인덱스가 counting[arr[i]] -> counting[arr[i]] - 1

좋은자료 항상 감사합니다 :)

Having a callback for when the selected element is changed would be useful, for similar reasons to TextEdit/LineEdit: validation, updating buffers, or the rest. I imagine that it would be something like selected(int) with int being the index, though LineEdit emits a simple callback without arguments so there may be a tradeoff I'm missing (an int should be easier to pass around on the oth
