cross-ci/lib/createVars.js

`cross-ci` standardizes environment variables for CI. For example, your can simply use `BUILD_BRANCH` variable in all CI runners instead of `CIRCLE_BRANCH` in CircleCI or `TRAVIS_PULL_REQUEST_BRANCH` in Travis.

const list = [
    'MONTH',
    'YEAR',
    'TIME',
    'TIMESTAMP',
    'CI_PLATFORM',
    'CI_NAME',
    'GIT_REMOTE',
    'GIT_PLATFORM',
    'RELEASE_BRANCHES',
    'PROJECT_NAME',
    'PROJECT_VERSION',
    'PROJECT_OWNER',
    'PROJECT_SLUG',
    'PROJECT_URL',
    'JOB_NUM',
    'JOB_URL',
    'BUILD_DIR',
    'BUILD_BRANCH',
    'BUILD_NUM',
    'BUILD_PR_NUM',

    'BUILD_COMMIT',
    'BUILD_COMMIT7',
    'BUILD_COMMIT_URL',
    'BUILD_COMMIT_PR_URL',

const createVars = (ci = {}) => {
    for (const name of list) {
        // eslint-disable-next-line import/no-dynamic-require
        ci[name] = require('./var/' + name)(ci);
    }
