Pretty print in MongoDB shell as default
提问by raffian
Is there a way to tell Mongo to pretty print output? Currently, everything is output to a single line and it's difficult to read, especially with nested arrays and documents.
有没有办法告诉 Mongo 漂亮的打印输出？目前，所有内容都输出到一行并且难以阅读，尤其是嵌套数组和文档。

You can ask it to be pretty.
你可以要求它漂亮。
db.collection.find().pretty()

You can add
你可以加
DBQuery.prototype._prettyShell = true
to your file in $HOME/.mongorc.jsto enable pretty print globally by default.
到您的文件中$HOME/.mongorc.js，默认情况下全局启用漂亮打印。

You can just do this on the CLI:
您可以在 CLI 上执行此操作：
echo DBQuery.prototype._prettyShell = true >> ~/.mongorc.js
And it's always going to output pretty results.
它总是会输出漂亮的结果。

Since it is basically a javascript shell, you can also use toArray():
由于它基本上是一个 javascript shell，因此您还可以使用toArray()：
db.collection.find().toArray()
However, this will print all the documents of the collection unlike pretty()that will allow you to iterate.
Refer: http://docs.mongodb.org/manual/reference/method/cursor.toArray/
但是，这将打印集合的所有文档，这与pretty()允许您进行迭代不同。参考：http: //docs.mongodb.org/manual/reference/method/cursor.toArray/

Oh so i guess .pretty() is equal to:
哦，所以我猜 .pretty() 等于：
db.collection.find().forEach(printjson);

Give a try to Mongo-hacker(node module), it alway prints pretty. https://github.com/TylerBrock/mongo-hacker
试试 Mongo-hacker（节点模块），它总是打印得很漂亮。 https://github.com/TylerBrock/mongo-hacker
More it enhances mongo shell (supports only ver>2.4, current ver is 3.0), like
更多它增强了 mongo shell（仅支持 ver>2.4，当前 ver 为 3.0），例如
- Colorization
- Additional shell commands (count documents/count docs/etc)
- API Additions (db.collection.find({ ... }).last(), db.collection.find({ ... }).reverse(), etc)
- Aggregation Framework
- 着色
- 额外的 shell 命令（计数文档/计数文档/等）
- API 添加（db.collection.find({ ... }).last(), db.collection.find({ ... }).reverse(), etc）
- 聚合框架
I am using for while in production env, no problems yet.
我在生产环境中使用了一段时间，还没有问题。

Got to the question but could not figure out how to print it from externally-loaded mongo. So:
得到了这个问题，但无法弄清楚如何从外部加载的 mongo 打印它。所以：
This works is for console:and is prefered in console, but does not work in external mongo-loaded javascript:
这适用于控制台：并且在控制台中是首选，但在外部 mongo 加载的 javascript 中不起作用：
db.quizes.find().pretty()
This works in external mongo-loaded javscript:
这适用于外部 mongo 加载的 javscript：
db.quizes.find().forEach(printjson)
