Semantic Tokens in MarkupString / MarkupContent - vscode-extensions

Is it possible to use MarkdownString/MarkupContent with code or pre with span to emulate semantic tokens in Hover? If so, is it possible to access the colors from the user's theme using only the CSS on the span elements? Ideally I would like to avoid using anything VSCode specific.
I saw https://github.com/microsoft/vscode/issues/97409 but there was no solution.

If you want to manually set colors for code you can try this:
// using your fileSelector
let disposable = vscode.languages.registerHoverProvider('plaintext', {
provideHover(document, position) {
const codeBlock = `<code><span style="color:#f00;background-color:#fff;">const</span> a = 12</code>`;
const markdown = new vscode.MarkdownString();
// markdown.appendCodeblock(codeBlock, "javascript");
markdown.appendMarkdown(codeBlock);
markdown.supportHtml = true;
markdown.isTrusted = true;
return new vscode.Hover(markdown, new vscode.Range(position, position));
}
});
<pre> also works, instead of <code>, but I think <code> looks better.

How to export vuelayers map to png or jpeg?

How would I adapt #ghettovoice JSFiddle that saves a map to PDF to save the map to a JPEG or PNG? I have no idea how to attempt this problem so ideally if you know hoe to do it you can explain the logic behind it.
exportMap: function () {
var map = this.$refs.map
map.once('rendercomplete', function () {
var mapCanvas = document.createElement('canvas');
var size = map.getSize();
mapCanvas.width = size[0];
mapCanvas.height = size[1];
var mapContext = mapCanvas.getContext('2d');
Array.prototype.forEach.call(
document.querySelectorAll('.ol-layer canvas'),
function (canvas) {
if (canvas.width > 0) {
var opacity = canvas.parentNode.style.opacity;
mapContext.globalAlpha = opacity === '' ? 1 : Number(opacity);
var transform = canvas.style.transform;
// Get the transform parameters from the style's transform matrix
var matrix = transform
.match(/^matrix\(([^(]*)\)$/)[1]
.split(',')
.map(Number);
// Apply the transform to the export map context
CanvasRenderingContext2D.prototype.setTransform.apply(
mapContext,
matrix
);
mapContext.drawImage(canvas, 0, 0);
}
}
);
if (navigator.msSaveBlob) {
// link download attribuute does not work on MS browsers
navigator.msSaveBlob(mapCanvas.msToBlob(), 'map.png');
} else {
var link = document.getElementById('image-download');
link.href = mapCanvas.toDataURL();
link.click();
}
});
map.renderSync();
}
The problem was a combination of missing dependencies (namely FileSaver.js and fakerator.js) and a cross origin server block (CORS block) (Browsers automatically prevent httpRequests to a different domain name unless the server allows it). The first one is fixed by installing the packages while the second one is resolved by setting the crossOrigin Attribute of the ImageWMSLayer to null in my case but possibly to 'Anonymous' for other sources. Hope this helped someone else :)

Adding embedded mode in docusaurus

I am using docusaurus 1.14.4
I need to create embedded mode for each document which remove header, footer and left navigation.
Page url look like this http://localhost:3000/...../?mode=emb
I figure out a way by adding this piece of script to each md file
<script>
function getParameterByName(name) {
var match = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search);
return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
}
var mode = getParameterByName('mode');
if (mode === 'emb') {
setTimeout(()=>{
let list = ['fixedHeaderContainer', 'docsNavContainer', 'nav-footer', 'docs-prevnext'];
for (var itemClassName of list) {
var item = document.getElementsByClassName(itemClassName)[0]
item.parentNode.removeChild(item)
}
document.getElementsByClassName('navPusher')[0].style.paddingTop = 0;
document.getElementsByClassName('mainContainer')[0].style.paddingTop = 0;
}, 0)
}
</script>
It work but does not look like a proper way. Can anyone suggest a better way?

Adobe Illustrator Scripting - Change Color of Selection

I'm trying to set the colour of my current selection in Illustrator using a .jsx script.
I can't find documentation on changing styles on (selected) objects. I have read most documentation out there, but I can't seem to find such a "simple" thing anywhere. Here is the code I've come up with:
thisThing = app.activeDocument.selection[0];
thisThing.filled = true;
thisThing.fillColor = '#ff0000';
When I run it, nothing happens sadly.
I have figured out a solution - it works, but it's very messy (due to being an edited solution). This gives a random grey colour to the selected item:
var myGrey= new CMYKColor()
myGrey.black=((Math.random()*80)+10);
if (app.documents.length && app.selection.length)
{
for (var a=0; a<app.selection.length; a++)
{
try {
app.selection[a].fillColor = myGrey;
} catch (e)
{
// ignoring all possible errors ...
}
}
}
In case you want to do non-grayscale: add myGrey.Yellow = value between 1-100;

How do I create easily a PDF from an SVG with jsPDF?

I'm trying to create a pdf but I have some SVG pictures. I found information about this problem, but I just have to use JavaScript, that's to say, no jQuery.
I found jsPDF here : https://github.com/MrRio/jsPDF
There is the plugin jspdf.plugin.sillysvgrenderer.js (in the same folder) and where we can find an exemple of PDF created in the folder test.
But when I try to generate the PDF on my own, it doesn't work and I don't understand why.
Do you know how to do it?
I got this plugin working, but only with SVG file from the tests and the I saw in the doc that only PATHs are supported :(
There is already the issue on github
https://github.com/MrRio/jsPDF/issues/384
If paths are ok for here is my code (it's more or less the code from the tests):
function demoSvgDocument() {
var doc = new jsPDF();
var test = $.get('013_sillysvgrenderer.svg', function(svgText){
var svgAsText = new XMLSerializer().serializeToString(svgText.documentElement);
doc.addSVG(svgAsText, 20, 20, doc.internal.pageSize.width - 20*2)
// Save the PDF
doc.save('TestSVG.pdf');
});
}
Another point to consider, you have to run all examples on a server. Otherwise you won't see any results probably because of the security
Try canvg for that to covert SVG to Canvas. Then convert the canvas to base64 string using .toDataURL().
More detailed answer is here https://stackoverflow.com/a/35788928/2090459
Check the demo here http://jsfiddle.net/Purushoth/hvs91vpq/
Canvg Repo: https://github.com/gabelerner/canvg
There now is svg2pdf.js which uses a fork of jsPDF.
It has been created to solve this exact task: Exporting an SVG to a PDF.
Also in the meantime, jsPDF also added a demo that shows how to possibly export SVG using canvg and the jsPDF canvas implementation.
The two solutions have different advantages and disadvantages, so you might want to try both and see if one of them suits your needs.
You can use the canvas plugin that comes with jsPDF to render the SVG on the PDF with canvg. I've had to set a few dummy properties on the jsPDF canvas implementation, and disable the interactive/animation features of canvg for this to work without errors:
var jsPdfDoc = new jsPDF({
// ... options ...
});
// ... whatever ...
// hack to make the jspdf canvas work with canvg
jsPdfDoc.canvas.childNodes = {};
jsPdfDoc.context2d.canvas = jsPdfDoc.canvas;
jsPdfDoc.context2d.font = undefined;
// use the canvg render the SVG onto the
// PDF via the jsPDF canvas plugin.
canvg(jsPdfDoc.canvas, svgSource, {
ignoreMouse: true,
ignoreAnimation: true,
ignoreDimensions: true,
ignoreClear: true
});
This seems to me a much better solution than the SVG plugin for jsPDF, as canvg has much better support of SVG features. Note that the width and height properties should be set on the <svg/> element of your SVG for canvg to render it correctly (or at least so it seemed to me).
I modified this from: https://medium.com/#benjamin.black/using-blob-from-svg-text-as-image-source-2a8947af7a8e
var yourSVG = document.getElementsByTagName('svg')[0];
//or use document.getElementById('yourSvgId'); etc.
yourSVG.setAttributeNS('http://www.w3.org/2000/xmlns/', 'xmlns', 'http://www.w3.org/2000/svg');
yourSVG.setAttributeNS('http://www.w3.org/2000/xmlns/', 'xmlns:xlink', 'http://www.w3.org/1999/xlink');
var serializer = new XMLSerializer();
var serialSVG = serializer.serializeToString(yourSVG);
var svg = serialSVG;
var blob = new Blob([svg], {type: 'image/svg+xml'});
var url = URL.createObjectURL(blob);
var image = document.createElement('img');
// image.addEventListener('load', () => URL.revokeObjectURL(url), {once: true});
//changed above line using babel to code below;
image.addEventListener('load', function () {
return URL.revokeObjectURL(url);
}, { once: true });
image.src = url;
//Then just use your pdf.addImage() function as usual;

Organizing JS code with Alloy and CommonJS in Titanium projects

I'm learning with Titanium to make iPhone/Android apps. I'm using Alloy MVC framework. I never used javascript before, apart from simple scripts in HTML to access the DOM or something like that, so I never needed to structure the code before.
Now, with Titanium, I must use a lot of JS code and I was looking for ways to structure my code. Basically I found 3 ways to do it: prototype, namespace and functions inside functions.
Simple example for each:
Prototype:
NavigationController = function() {
this.windowStack = [];
};
NavigationController.prototype.open = function(windowToOpen) {
//add the window to the stack of windows managed by the controller
this.windowStack.push(windowToOpen);
//grab a copy of the current nav controller for use in the callback
var that = this;
windowToOpen.addEventListener('close', function() {
if (that.windowStack.length > 1)
{
that.windowStack.pop();
}
});
if(Ti.Platform.osname === 'android') {
windowToOpen.open();
} else {
this.navGroup.open(windowToOpen);
}
};
NavigationController.prototype.back = function(w) {
//store a copy of all the current windows on the stack
if(Ti.Platform.osname === 'android') {
w.close();
} else {
this.navGroup.close(w);
}
};
module.exports = NavigationController;
Using it as:
var NavigationController = require('navigator');
var navController = new NavigationController();
Namespace (or I think is something like that, coz the use of me = {}):
exports.createNavigatorGroup = function() {
var me = {};
if (OS_IOS) {
var navGroup = Titanium.UI.iPhone.createNavigationGroup();
var winNav = Titanium.UI.createWindow();
winNav.add(navGroup);
me.open = function(win) {
if (!navGroup.window) {
// First time call, add the window to the navigator and open the navigator window
navGroup.window = win;
winNav.open();
} else {
// All other calls, open the window through the navigator
navGroup.open(win);
}
};
me.setRightButton = function(win, button) {
win.setRightNavButton(button);
};
me.close = function(win) {
if (navGroup.window) {
// Close the window on this nav
navGroup.close(win);
}
};
};
return me;
};
Using it as:
var ui = require('navigation');
var nav = ui.createNavigatorGroup();
Functions inside functions:
function foobar(){
this.foo = function(){
console.log('Hello foo');
}
this.bar = function(){
console.log('Hello bar');
}
}
// expose foobar to other modules
exports.foobar = foobar;
Using it as:
var foobar = require('foobar').foobar
var test = new foobar();
test.bar(); // 'Hello bar'
And now my question is: which is the better to maintain code clean and clear? It seems that prototype is clear an easy to read/mantain. Namespace confuses me a bit but only needs to execute the initial function to be "available" (no use of new while declaring it, I suppose because it returns the object?namespace? "me"). Finally, functions inside functions is similar to the last, so I don't know exactly the difference, but is useful to export only the main function and have all the inside functions available for use it later.
Maybe the last two possibilities are the same, and I'm messing concepts.
Remember that I'm searching for a good way to structure the code and have functions available to other modules and also inside the own module.
I appreciate any clarification.
In the examples that they release, Appcelerator appears to follow the non-prototype approach. You can see it in the examples they have released: https://github.com/appcelerator/Field-Service-App.
I've seen a lot of different approaches to structuring applications in Titanium before Alloy. Since Alloy, I've found following the development team's examples helpful to me.
With that being said, it seems to me that all of this is still under interpretation and open to change and community development. Before Alloy there were some great community suggestions on structuring an app and I believe that it is still open with Alloy. Often when I find someone's example code I see something they did with it that appears to organize it a bit better than I thought of. It seems to make it a bit easier.
I think you should structure your application in a way that makes sense to you. You may stumble on to a better and easier way of developing applications with Alloy, because you are looking at it critically.
I haven't found a lot of extensive Alloy examples, but Field-Service-App makes sense to me. They have a nice separation of the elements in the application beyond MVC. Check it out.
