tsc

问题 I have an embedded Linux system running on an Atom, which is a new enough CPU to have an invariant TSC (time stamp counter), whose frequency the kernel measures on startup. I use the TSC in my own code to keep time (avoiding kernel calls), and my startup code measures the TSC rate, but I'd rather just use the kernel's measurement. Is there any way to retrieve this from the kernel? It's not in /proc/cpuinfo anywhere. 回答1: I had a brief look and there doesn't seem to be a built-in way to

问题 This is how my tsconfig.json file looks: { "compileOnSave": true, "compilerOptions": { "module": "amd", "noImplicitAny": false, "removeComments": false, "preserveConstEnums": true, "strictNullChecks": true, "sourceMap": false } } I have a typescript file named a.ts which is an AMD module (I'm using requirejs), which looks like: export function a() { var a = { b: 5 }; return a; } The compiled Javascript files looks like: define(["require", "exports"], function (require, exports) { "use strict"

问题 In our project we're using RequireJS as our module loader. Some of our modules will influence global libraries, and hence won't be directly used within the module they are referenced in. Example: define(['definitely/goingto/usethis/','just/referencingthis/forpackaging'], function(useThis) { useThis.likeIPromised(); // the following call can only be made when the second required file is available someGlobalAvailableVariable.someMethod(); }); This works as expected when writing my modules in

问题 Just installed Typescript extension to VS2012 and followed Install TypeScript for Visual Studio 2012 and then the tutorial to call the compiler: > tsc greeter.ts But when i try to compile .ts file where should i type: tsc greeter.ts ?

问题 I'm using a lot of libraries both my own and 3rd party. I see the "typings" directory contains some for Jquery and WinRT... but how are they created? 回答1: There are a few options available for you depending on the library in question, how it's written, and what level of accuracy you're looking for. Let's review the options, in roughly descending order of desirability. Maybe It Exists Already Always check DefinitelyTyped (https://github.com/DefinitelyTyped/DefinitelyTyped) first. This is a

问题 I am using node version 6.9.2 with npm version 5.4.2 on Windows7. I have installed typescript with the command npm install typescript -g . However, when I run a demo file using command, tsc , I get an error: "tsc is not recognized as an internal or external command". Could anybody help? Other node modules get installed correctly and working fine. Not sure why typescript isn't working. 回答1: The problem is likely that tsc is not in the system path. First, check if tsc is installed correctly.

问题 Say I have this type: export interface Opts { paths?: string | Array<string>, path?: string | Array<string> } I want to tell the user that they must pass either paths or path, but it is not necessary to pass both. Right now the problem is that this compiles: export const foo = (o: Opts) => {}; foo({}); does anyone know to allow for 2 or more optional but at least 1 is necessary parameters with TS? 回答1: You may use export type Opts = { path: string | Array<string> } | { paths: string | Array

问题 Maybe it's a duplicate but I've searched for an hour and haven't found the answer. I have a node module named a-module which contains some .ts files (for example a.ts ) I have another node module b-module which has a-module among its dependencies. I want to import some .ts file from a-module to b-module . In some file within b-module I write: import a = require('a-module/a'); console.log(a); When then I'm trying to compile b-module with tsc, is says Cannot find external module 'a-module/a'.
