Show results from hover providers incrementally #137714
Description
When having multiple hover providers, it would be good to render results as soon as possible and not block on waiting for all hover providers. Sample:
package.json:
{
"name": "137714",
"publisher": "alex",
"version": "0.0.1",
"engines": {
"vscode": "^1.22.0"
},
"activationEvents": ["*"],
"main": "main.js"
}main.js:
//@ts-check
const vscode = require("vscode");
/**
*
* @param {string} message
* @param {number} timeout
*/
function createProvider(message, timeout) {
return (
/**
* @param {import('vscode').TextDocument} document
* @param {import('vscode').Position} position
*/
function provideHover(document, position) {
return new Promise((resolve, reject) => {
setTimeout(() => {
resolve(new vscode.Hover(new vscode.MarkdownString(message)));
}, timeout);
});
}
);
}
/**
* @param {string} message
* @param {number} timeout
*/
function registerProvider(message, timeout) {
const provideHover = createProvider(message, timeout);
vscode.languages.registerHoverProvider({ language: 'typescript', }, { provideHover });
}
exports.activate = function (ctx) {
registerProvider('Slow provider', 5000);
registerProvider('Fast provider', 1000);
registerProvider('Very fast provider', 0);
};
