node-vcvarsall v1.0.1

node-vcvarsall

Retreives the environment variables set by running the vcvarsall.bat script.

The resulting object represents the delta between the system environment and a Developer Command Prompt's environment. Variables that are modified by the vcvarsall.bat script are returned without the value from the original environment - instead using %varName% (e.g. %Path% for variable Path) as a placeholder for the variable's original value.

Usage

definition

namespace vcvars {

    function getVCVars(vsInstallation: vswhere.Installation, options?: Options): Promise<Vars>;

}

example

import { vswhere } from 'node-vswhere';
import { vcvars } from 'node-vcvarsall';

// Find only VS installations that include the MSVC toolset.
const installations = await vswhere.getVSInstallations({
        all: true,
        sort: true,
        prerelease: true,
        requires: ['Microsoft.VisualStudio.Component.VC.Tools.x86.x64']
    })
    .catch(err => []);

if (installations.length > 0) {
    const vars = await vcvars.getVCVars(installations[0]);
}
