I want to set fast forward shortcut for my player. I found this shortcuts in hotkeys plugin
Space bar toggles play/pause.
Right and Left Arrow keys seek the video forwards and back.
Up and Down Arrow keys increase and decrease the volume.
M key toggles mute/unmute.
F key toggles fullscreen off and on. (Does not work in Internet Explorer, it seems to be a limitation where scripts cannot request fullscreen without a mouse click)
Double-clicking with the mouse toggles fullscreen off and on.
Number keys from 0-9 skip to a percentage of the video. 0 is 0% and 9 is 90%.

Is there any key for fast-forwarding?

I’m trying to send a message to a specific channel on discord, however it tells me that channel.send is not a function. I’ve entered the correct channel id though, what could be the issue ? Here’s my function code and a snapshot :

function discordsend(usern)
{ 
    usern="someusername#1234"
    string = "somethingsomething"+usern;
    const channel = 
client.channels.cache.get('946932969359179786')||client.channels.fetch('946932969359179786');
    channel.send(string);
}

In the end, I need Latitude/Longitude coordinates. On a webpage, I need a zoomable map, preferably with a cross in the center, and an OK button. The user moves and zooms the map, and then clicks the OK button, which gives the page (JavaScript) the lat-long coordinates of the current center of the map.

Also, a type-in field on the map would be nice, so the user can get to the area more easily.

Could someone please point me to the right direction? I’m completely new to this field.

Openstreetmap is preferred, but Google Maps can be arranged, if necessary.

Thank you in advance.

I’m working on updating the TinyColor RegExp and I recently added angles and percent based alpha into the mix to be able to compute CSS4 Module color strings.

Please have a look at the following sample snippet:

const ANGLES = 'deg|rad|grad|turn';
const CSS_INTEGER = '[-\+]?\d+%?';
const CSS_NUMBER = '[-\+]?\d*\.\d+%?';
const CSS_ANGLES = `[-\+]?\d*\.?\d+(?:${ANGLES})?`;

const CSS_UNIT = `(?:${CSS_NUMBER})|(?:${CSS_INTEGER})`;
const CSS_UNIT2 = `${CSS_UNIT}|(?:${CSS_ANGLES})`;

const PERMISSIVE_MATCH3 = `[\s|\(]+(${CSS_UNIT2})[,|\s]+(${CSS_UNIT})[,|\s]+(${CSS_UNIT})\s*\)?`;
const PERMISSIVE_MATCH4 = `[\s|\(]+(${CSS_UNIT2})[,|\s]+(${CSS_UNIT})[,|\s]+(${CSS_UNIT})[,|\s|\/]+(${CSS_UNIT})\s*\)?`;

const matchers = {
  hsl: new RegExp(`[hsl|hsla]+(?:${PERMISSIVE_MATCH4})`),
  hsl2: new RegExp(`[hsl|hsla]+(?:${PERMISSIVE_MATCH4})|(?:${PERMISSIVE_MATCH3})`),
  hsl3: new RegExp(`[hsl|hsla]+(?:${PERMISSIVE_MATCH3})|(?:${PERMISSIVE_MATCH4})`),
};

console.log('hsl - null', matchers.hsl.exec('hsl(120, 100%, 50%)'));
console.log('hsl - correct', matchers.hsl.exec('hsla(120, 100%, 50%, 0.5)'));
console.log('hsl - null', matchers.hsl.exec('hsl(120deg 100% 50%)'));
console.log('hsl - correct', matchers.hsl.exec('hsl(120deg 100% 50% 50%)'));

console.log('hsl2 - wrong indexes', matchers.hsl2.exec('hsl(120, 100%, 50%)'));
console.log('hsl2 - correct', matchers.hsl2.exec('hsla(120, 100%, 50%, 0.5)'));
console.log('hsl2 - wrong indexes', matchers.hsl2.exec('hsl(120deg 100% 50%)'));
console.log('hsl2 - correct', matchers.hsl2.exec('hsl(120deg 100% 50% 50%)')); // returns correct

console.log('hsl3 - correct', matchers.hsl3.exec('hsl(120, 100%, 50%)'));
console.log('hsl3 - incomplete', matchers.hsl3.exec('hsla(120, 100%, 50%, 0.5)'));
console.log('hsl3 - correct', matchers.hsl3.exec('hsl(120deg 100% 50%)'));
console.log('hsl3 - incomplete', matchers.hsl3.exec('hsl(120deg 100% 50% 50%)'));

I need to change PERMISSIVE_MATCH4 to work will matchers.hsl in all variations and return the matches in the same order and format:

output = [
'hsl(120deg 100% 50% 50%)', // the input capture
'120deg', // HUE first value
'100%', // SATURATION second value
'50%', // LIGHTNESS third value
'50%', // ALPHA last and OPTIONAL value
 // ... other matches results
]

I’m open to suggestions and I thank you for any reply.

in angular material it provide matTooltip attribute to show tooltip . i want to show arrow with tooltip pointing towards overflow text. but tooltip position is dynamic based on target element position in corners , top or bottom based on that appending arrow in tooltip design as per tooltip position is difficult , i applied bellow solution but works only if i open tooltip at specified position top, bottom , left or right

.mat-tooltip::before {
      content     : '';
      display     : block;
      position    : absolute;
      bottom      : 100%;
      border-style: solid;
      border-color: transparent transparent #3E464E transparent;
      border-width: 12px;
      left        : calc(50% - 12px);
}  


<div class="title-ellips"
   matTooltipClass="custom-tooltip"
   matTooltip="{{exam | examColumnValue: column}}"
  *ngIf="((exam[column]) && ((exam | examColumnValue: column).toString().length>=30))"
   placement="top" data-container="body" tooltipClass="customTableTooltip">
  {{exam | examColumnValue: column}}
</div>

I need help tweaking the code for this:

const posts = await PostMessage.find({ $or: [ { title }, { tags: { $in: tags.split(',') } } ]});

At the moment, you can filter for posts using a search form which has title and posts. You can leave one empty when you search. It works fine except when you use both. For example searching “hiking” and tagging “Europe” would show posts for both hiking titles AND Europe tags (when I would want the search narrowed down to only show posts with the title hiking and tagged Europe). I know that I can use $and in place of $or but that only returns posts if the user enters both title and tags when I want to give the user the option to leave one blank. Can someone help me write out the code for that?

From what I’ve seen I was wondering if I could do something like this:

Or: {
(And: title not null, tags not null )
(Or title null, tags not null)
(Or title not null, tags null)
)

Is this possible to do? I can’t find a similar example. Thanks for the help!

Still trying to get my head around typescript so please forgive me but my searches have yielded me no answers. All my other types have worked well but I just can’t figure out how to get the value in style.setProperty(propertyName, value) to accept the number.

      vari.style.setProperty('--rotation', rotationRatio * 360);
    }

I have JS and PHP scripts that uploads a file to Pinata (IPFS) and it all works fine but I first need to upload the file to my web server then it can be uploaded to IPFS. This is not a good solution for large files because I need to wait for 2 uploads to happen before I get the returned CID.

Is it possible to upload directly to Pinata without first uploading to my server? Ultimately im going to setup my own Arweave node in the future but am currently using a paid account on Pinata.
