我想myConstantsFile.js用另一个字符串替换指示javascript文件（）中版本号的字符串。因此，例如，我的版本号看起来像这样：“ 01.11.15”，myConstantsFile.js用其他常量这样写：
.constant('productVersion', '1.11.15');
现在，我的任务如下所示：
gulp.task('increment-version', function(){
gulp.src(['./somedir/myConstantsFile.js'])
.pipe(replace(/'productVersion', '(.*)'/g, '99.99.99'))
.pipe(gulp.dest('./somedir/'));
});
如您所见，我正在使用一个常量，而不是运行增量代码，它看起来像这样：
var numberString = '0.0.1';
var versionParts = numberString.split('.');
var vArray = {
vMajor : versionParts[0],
vMinor : versionParts[1],
vPatch : versionParts[2]
}
vArray.vPatch = parseFloat(vArray.vPatch) + 1;
var periodString = ".";
var newVersionNumberString = vArray.vMajor + periodString +
vArray.vMinor+ periodString +
vArray.vPatch;
我需要：
npm install gulp-bump --save-dev
安装yargs
npm install yargs --save-dev
需要大吃一惊
var bump = require('gulp-bump');
需要yargs
var args = require('yargs').argv;
你的颠簸任务
gulp.task('bump', function () {
/// <summary>
/// It bumps revisions
/// Usage:
/// 1. gulp bump : bumps the package.json and bower.json to the next minor revision.
/// i.e. from 0.1.1 to 0.1.2
/// 2. gulp bump --version 1.1.1 : bumps/sets the package.json and bower.json to the
/// specified revision.
/// 3. gulp bump --type major : bumps 1.0.0
/// gulp bump --type minor : bumps 0.1.0
/// gulp bump --type patch : bumps 0.0.2
/// gulp bump --type prerelease : bumps 0.0.1-2
/// </summary>
var type = args.type;
var version = args.version;
var options = {};
if (version) {
options.version = version;
msg += ' to ' + version;
} else {
options.type = type;
msg += ' for a ' + type;
}
return gulp
.src(['Path to your package.json', 'path to your bower.json'])
.pipe(bump(options))
.pipe(gulp.dest('path to your root directory'));
});
VSO注意：我相信很多参加此话题的人都将确切地寻找上述答案。下面的代码用于编辑存储在npm / bower软件包文件之外的版本号，例如角度常数：
gulp.task('increment-version', function(){
//docString is the file from which you will get your constant string
var docString = fs.readFileSync('./someFolder/constants.js', 'utf8');
//The code below gets your semantic v# from docString
var versionNumPattern=/'someTextPreceedingVNumber', '(.*)'/; //This is just a regEx with a capture group for version number
var vNumRexEx = new RegExp(versionNumPattern);
var oldVersionNumber = (vNumRexEx.exec(docString))[1]; //This gets the captured group
//...Split the version number string into elements so you can bump the one you want
var versionParts = oldVersionNumber.split('.');
var vArray = {
vMajor : versionParts[0],
vMinor : versionParts[1],
vPatch : versionParts[2]
};
vArray.vPatch = parseFloat(vArray.vPatch) + 1;
var periodString = ".";
var newVersionNumber = vArray.vMajor + periodString +
vArray.vMinor+ periodString +
vArray.vPatch;
gulp.src(['./someFolder/constants.js'])
.pipe(replace(/'someTextPreceedingVNumber', '(.*)'/g, newVersionNumber))
.pipe(gulp.dest('./someFolder/'));
});
我省略了一些将其常量写成漂亮字符串的巨型组合，但这就是要点，并且有效。
