使用j替換多個JSON對象的所有值

我試圖用jq替換所有值爲*（星號字符）的JSON對象。使用j替換多個JSON對象的所有值

這是我的package.json文件：

{ 
    "name": "project", 
    "version": "0.0.1", 
    "description": "project-desc", 
    "main": "gulpfile.js", 
    "directories": { 
    "test": "tests" 
    }, 
    "dependencies": { 
    "babel-polyfill": "^6.7.4", 
    "babel-preset-es2015": "^6.6.0", 
    "babel-preset-react": "^6.5.0", 
    "gulp-clean": "^0.3.2", 
    "jquery": "^2.1.4", 
    "lodash": "^4.0.0", 
    "moment": "^2.13.0", 
    "moment-timezone": "^0.5.0", 
    "radium": "^0.16.2", 
    "react": "^15.1.0", 
    "react-bootstrap-sweetalert": "^1.1.10", 
    "react-dom": "^15.1.0", 
    "react-timeago": "^2.2.1", 
    "sprintf": "^0.1.5", 
    "smoothscroll": "~0.2.2" 
    }, 
    "devDependencies": { 
    "babel": "^6.3.26", 
    "babelify": "^7.2.0", 
    "browserify": "^12.0.1", 
    "console-stamp": "^0.2.0", 
    "estraverse-fb": "^1.3.1", 
    "gulp": "^3.9.0", 
    "gulp-concat": "^2.6.0", 
    "gulp-sass": "^2.1.1", 
    "gulp-sourcemaps": "^1.6.0", 
    "gulp-util": "^3.0.7", 
    "lodash": "^4.5.1", 
    "lodash.assign": "^3.2.0", 
    "lodash.isfunction": "^3.0.8", 
    "lodash.reduce": "^4.3.0", 
    "node-sass": "^3.4.2", 
    "react-bootstrap": "^0.29.4", 
    "react-intl": "^2.1.0", 
    "reactify": "^1.1.1", 
    "sweetalert": "^1.1.3", 
    "vinyl": "^1.1.0", 
    "vinyl-buffer": "^1.0.0", 
    "vinyl-source-stream": "^1.1.0", 
    "watchify": "^3.4.0", 
    "jsx-to-string": "~0.2.11" 
    }, 
    "optionalDependencies": { 
    "pkg-save": "~1.0.2" 
    }, 
    "scripts": { 
    "test": "echo \"Error: no test specified\" && exit 1" 
    }, 
    "repository": { 
    "type": "git", 
    "url": "mygiturl" 
    }, 
    "author": "authorname", 
    "license": "MIT" 
}

我想用星號來代替dependencies，devDependencies和optionalDependencies對象的所有值，像這樣（以下簡稱爲例）：

... 
"devDependencies": { 
     "babel": "*", 
     "babelify": "*", 
     "browserify": "*", 
     "console-stamp": "*", 
...

下面是我正在使用的過濾器：
.dependencies, .devDependencies, .optionalDependencies | .foreach .[] as $item ([]; $item = "*")
通過命令行傳遞爲：
cat package.json | jq '.dependencies, .devDependencies, .optionalDependencies | .foreach .[] as $item ([]; $item = "*")'

它雖然返回一個錯誤，而不是期望的結果：

error: syntax error, unexpected '[', expecting IDENT 
.dependencies, .devDependencies, .optionalDependencies | .foreach .[] as $item ([]; $item = "*") 
                   ^
1 compile error

不僅僅是作爲一個語法錯誤，我敢肯定，這只是操縱頂級項目，而不是每個鍵對象內的價值對，這是我打算做的。

來完成這項任務很可能是使用下面的過濾器的最直接的方式：

爲了避免重複：

(.dependencies, .devDependencies, .optionalDependencies) |= map_values("*")

你可以通過採取逗號運營商的優勢，更新所有的一舉。要將所有值更新到"*"，您可以這樣做：

.["dependencies", "devDependencies", "optionalDependencies"] |= map_values("*")
