31I want the suggestion to appear as possible completion, but without actually completing it (for display purposes). This question has been asked before, but to this date no answer is given.
Regarding-o nosort
I look into that option and it's only available at Bash 4.4+, I tried on my 16.04 machine and it fail. Looking for more globalish solution

UPDATE:
is it possible to move the empty string to end of completion, so it doesn't look like there are empty space?
You can use complete -o nosort (requires Bash 4.4+) if you can sort the completion candidates all by yourself.
QUESTION
React/Socket.io not displaying latest message passed down as prop
Asked 2022-Jan-13 at 17:37I am working on a chat application using React and socket.io. Back end is express/node. The relevant components are: Room.js --> Chat.js --> Messages.js --> Message.js
messageData received from the server is stored in state in Room.js. It is then passed down through Chat.js to Messages.js, where it is mapped onto a series of Message.js components.
When messages are received, they ARE appearing, but only after I start typing in the form again, triggering messageChangeHandler(). Any ideas why the Messages won't re-render when a new message is received and added to state in Room.js? I have confirmed that the state and props are updating everywhere they should be--they just aren't appearing/re-rendering until messageChangeHandler() triggers its own re-render.
Here are the components.
Room.js

4 useEffect(() => {
5 console.log('the use effect ')
6 socket.on('broadcast', data => {

QUESTION
Getting keyboard navigation to work with MUI Autocomplete and SimpleBar for react
Asked 2021-Dec-30 at 20:06I am trying to add Simplebar scrollbar to the MUI Material Autocomplete component, instead of the default browser one. All works but doing that I've lost the ability to navigate the options list with the keyboard.
There is this snippet from the MUI docs
ListboxComponent If you provide a custom ListboxComponent prop, you need to make sure that the intended scroll container has the role attribute set to listbox. This ensures the correct behavior of the scroll, for example when using the keyboard to navigate.
But I have no idea how to do that.
The following code is from the MUI docs, first autocomplete example with custom ListboxComponenet and shortened movie list. (https://mui.com/components/autocomplete/)
1import * as React from 'react';
2import TextField from '@mui/material/TextField';
3import Autocomplete from '@mui/material/Autocomplete';
4
5import SimpleBar from "simplebar-react";
6import "simplebar/dist/simplebar.min.css";

8export default function ComboBox() {
9 return (
10 <Autocomplete
11 disablePortal
12 id="combo-box-demo"
13 options={top100Films}
14 ListboxComponent={SimpleBar}
15 sx={{ width: 300 }}
16 renderInput={(params) => <TextField {...params} label="Movie" />}
17 />
18 );
19}

52Any help would be appreciated, thanks.
ANSWER
Answered 2021-Dec-30 at 20:06The problem is actually very complicated. Looking at its implementation, <SimpleBar /> doesn't pass either the React ref or the role prop to the correct element. The correct element I believe is .scrollbar-content, which is very deeply nested and basically untouchable.
ETA: In case you thought of getting cheesy with document.querySelectorAll setAttribute shenanigans, that will not work. The ref also needs to point at the correct element, and I don't think that's codeable on the workspace side.
The cleanest solution I can think of is to use Yarn 3 (👍) and patch simplebar-react yourself, passing the needed props to .scrollbar-content. Then you do:
1import * as React from 'react';
2import TextField from '@mui/material/TextField';
3import Autocomplete from '@mui/material/Autocomplete';
4
5import SimpleBar from "simplebar-react";
6import "simplebar/dist/simplebar.min.css";

52const ListboxSimpleBar = React.forwardRef(function ListboxSimpleBar(props, ref) {
53 return <SimpleBar {...props} role='listbox' listboxRef={ref} />
54}
55
56// ...
57ListboxComponent={ListboxSimpleBar}
58The less clean solution is to fork the repo, patch it, and install it as a git dependency. Or publish to npm once you're sure it works and install as a regular dependency. That's the recommended method if you don't use Yarn 3 (👎). It's much more tedious and won't receive updates, but it is an option that exists.
The least clean solution is to copypasterino the simplebar-react code in your own workspace, edit it and import it in lieu of the real simplebar-react. Hackier, messier and funnier option 2, but only just barely.

Why typescript does not properly infer T[K] with <T extends Person, K extends keyof T> generic?
Asked 2021-Dec-18 at 21:55I have created a React hook:
1interface Person {
2 name: string
3 age: number
4}
5
6export const usePerson = function <T extends Person, K extends keyof T>(): (property: K, setter: (value: T[K]) => T[K]) => void {
7
8 const setPersonProperty = (property: K, setter: (value: T[K]) => T[K]): void => {
9 console.log(property, setter)
10 }
11
12 setPersonProperty('name', (x) => x)
13
14 return setPersonProperty;
15}
16I have seen the pattern <T, K extends keyof T> from typescript docs but I am unable to use it correctly in my example.
More specifically, the typescript complains on the line
1interface Person {
2 name: string
3 age: number
4}
5
6export const usePerson = function <T extends Person, K extends keyof T>(): (property: K, setter: (value: T[K]) => T[K]) => void {
7
8 const setPersonProperty = (property: K, setter: (value: T[K]) => T[K]): void => {
9 console.log(property, setter)
10 }
11
12 setPersonProperty('name', (x) => x)
13
14 return setPersonProperty;
15}
16setPersonProperty('name', (x) => x)
17Although when I start typing setPersonProperty('n /* IDE autocompletes name */ but complains for the 'name' parameter and I get the following error:
1interface Person {
2 name: string
3 age: number
4}
5
6export const usePerson = function <T extends Person, K extends keyof T>(): (property: K, setter: (value: T[K]) => T[K]) => void {
7
8 const setPersonProperty = (property: K, setter: (value: T[K]) => T[K]): void => {
9 console.log(property, setter)
10 }
11
12 setPersonProperty('name', (x) => x)
13
14 return setPersonProperty;
15}
16setPersonProperty('name', (x) => x)
17Argument of type 'string' is not assignable to parameter of type 'K'. 'string' is assignable to the constraint of type 'K', but 'K' could be instantiated with a different subtype of constraint 'string | number | symbol'.
18I have also posted an image from my IDE. I am using typescript 4+. [![enter image description here][1]][1]
What am I doing wrong here ? [1]: https://i.stack.imgur.com/WzJE5.png
ANSWER
Answered 2021-Dec-18 at 21:55I bet that this is the result You want to achieve
1interface Person {
2 name: string
3 age: number
4}
5
6export const usePerson = function <T extends Person, K extends keyof T>(): (property: K, setter: (value: T[K]) => T[K]) => void {
7
8 const setPersonProperty = (property: K, setter: (value: T[K]) => T[K]): void => {
9 console.log(property, setter)
10 }
11
12 setPersonProperty('name', (x) => x)
13
14 return setPersonProperty;
15}
16setPersonProperty('name', (x) => x)
17Argument of type 'string' is not assignable to parameter of type 'K'. 'string' is assignable to the constraint of type 'K', but 'K' could be instantiated with a different subtype of constraint 'string | number | symbol'.
18type Person = {
19 name: string,
20 age: number
21};
22
23export const usePerson = function <T extends Person>() {
24 const setPersonProperty = <K extends keyof T> (property: K, setter: (value: T[K]) => T[K]): void => {
25 console.log(property, setter)
26 }
27
28 setPersonProperty("name", (x) => x)
29
30 return setPersonProperty;
31}
32
33 const setPerson = usePerson<Person>()
34
35 setPerson("name", (name) => name)
36
37Basically, in code you provided there are two generic types when calling this usePerson hook T and K (<T extends Person, K extends keyof T>).
Let's say someone will call this function with usePerson<Person, "age">().
What typescript will do it will replace types inside our usePerson to be T = Person and K = "age"
And now you have a mismatch since setPersonProperty have first argument of type K ("age") the argument "name" is not assignable - that the error you see.

8}
9Here is what I want to achieve, to make it becomes:
1interface IPerson {
2 name: string;
3 age: number;
4 contact: {
5 address: string;
6 visitDate: Date;
7 }
8}
9type TPerson = {
10 name: string;
11 age: number;
12 contact: { address: string; visitDate: Date; }
13 "contact.address": string;
14 "contact.visitDate": Date;
15}
16
What I have tried:
In this answer, I can get the key with Leaves<IPerson>.
So it becomes 'name' | 'age' | 'contact.address' | 'contact.visitDate'.
And in another answer from @jcalz, I can get the deep, related value type, with DeepIndex<IPerson, ...>.
Is it possible to group them together, to become type like TPerson?
When I start this question, I was thinking it could be as easy as something like [K in keyof T]: T[K];, with some clever transformation. But I was wrong. Here is what I need:
So the interface
1interface IPerson {
2 name: string;
3 age: number;
4 contact: {
5 address: string;
6 visitDate: Date;
7 }
8}
9type TPerson = {
10 name: string;
11 age: number;
12 contact: { address: string; visitDate: Date; }
13 "contact.address": string;
14 "contact.visitDate": Date;
15}
16interface IPerson {
17 contact: {
18 address: string;
19 visitDate: Date;
20 }[]
21}
22becomes
1interface IPerson {
2 name: string;
3 age: number;
4 contact: {
5 address: string;
6 visitDate: Date;
7 }
8}
9type TPerson = {
10 name: string;
11 age: number;
12 contact: { address: string; visitDate: Date; }
13 "contact.address": string;
14 "contact.visitDate": Date;
15}
16interface IPerson {
17 contact: {
18 address: string;
19 visitDate: Date;
20 }[]
21}
22type TPerson = {
23 [x: `contact.${number}.address`]: string;
24 [x: `contact.${number}.visitDate`]: Date;
25 contact: {
26 address: string;
27 visitDate: Date;
28 }[];
29}
30No need to check for valid number, the nature of Array / Index Signature should allow any number of elements.
The interface
1interface IPerson {
2 name: string;
3 age: number;
4 contact: {
5 address: string;
6 visitDate: Date;
7 }
8}
9type TPerson = {
10 name: string;
11 age: number;
12 contact: { address: string; visitDate: Date; }
13 "contact.address": string;
14 "contact.visitDate": Date;
15}
16interface IPerson {
17 contact: {
18 address: string;
19 visitDate: Date;
20 }[]
21}
22type TPerson = {
23 [x: `contact.${number}.address`]: string;
24 [x: `contact.${number}.visitDate`]: Date;
25 contact: {
26 address: string;
27 visitDate: Date;
28 }[];
29}
30interface IPerson {
31 contact: [string, Date]
32}
33becomes
1interface IPerson {
2 name: string;
3 age: number;
4 contact: {
5 address: string;
6 visitDate: Date;
7 }
8}
9type TPerson = {
10 name: string;
11 age: number;
12 contact: { address: string; visitDate: Date; }
13 "contact.address": string;
14 "contact.visitDate": Date;
15}
16interface IPerson {
17 contact: {
18 address: string;
19 visitDate: Date;
20 }[]
21}
22type TPerson = {
23 [x: `contact.${number}.address`]: string;
24 [x: `contact.${number}.visitDate`]: Date;
25 contact: {
26 address: string;
27 visitDate: Date;
28 }[];
29}
30interface IPerson {
31 contact: [string, Date]
32}
33type TPerson = {
34 [x: `contact.0`]: string;
35 [x: `contact.1`]: Date;
36 contact: [string, Date];
37}
38Tuple should be the one which cares about valid index numbers.
3. Readonlyreadonly attributes should be removed from the final structure.

46The use case is for MongoDB, the _id, _created_date cannot be modified after the data has been created. _id: never is not working in this case, since it will block the creation of TPerson.

81We can give a list of Types to be the end node.
Here is what I don't need:- Union. It could be too complex with it.
- Class related keyword. No need to handle keywords ex: private / abstract .
- All the rest I didn't write it here.
ANSWER
Answered 2021-Dec-02 at 09:30In order to achieve this goal we need to create permutation of all allowed paths. For example:

92Problem becomes more interesting with arrays and empty tuples.
Tuple, the array with explicit length, should be managed in this way:

6 visitDate: Date;
7 }
8}
9type TPerson = {

12 contact: { address: string; visitDate: Date; }
13 "contact.address": string;
14 "contact.visitDate": Date;
15}

102Logic is straitforward. But how we can handle number[]? There is no guarantee that index 1 exists.
I have decided to use user.arr.${number}.

112We still have 1 problem. Empty tuple. Array with zero elements - []. Do we need to allow indexing at all? I don't know. I decided to use -1.

122I think the most important thing here is some convention. We can also use stringified `"never". I think it is up to OP how to handle it.
Since we know how we need to handle different cases we can start our implementation. Before we continue, we need to define several helpers.

201There is small issue. We should not return highest level props, like user. We need paths with at least one dot.
There are two ways:
- extract all props without dots
- provide extra generic parameter for indexing the level.
Two options are easy to implement.
Obtain all props with dot (.):
