Pretty print in MongoDB shell as default
MongodbCommand Line-InterfaceMongo ShellMongodb Problem Overview
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.
Mongodb Solutions
Solution 1 - Mongodb
(note: this is answer to original version of the question, which did not have requirements for "default")
You can ask it to be pretty.
db.collection.find().pretty()
Solution 2 - Mongodb
You can add
DBQuery.prototype._prettyShell = true
to your file in $HOME/.mongorc.js to enable pretty print globally by default.
Solution 3 - Mongodb
(note: this is answer to the updated question)
You can just do this on the CLI:
echo DBQuery.prototype._prettyShell = true >> ~/.mongorc.js
And it's always going to output pretty results.
Solution 4 - Mongodb
Since it is basically a javascript shell, you can also use 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/
Solution 5 - Mongodb
Oh so i guess .pretty() is equal to:
db.collection.find().forEach(printjson);
Solution 6 - Mongodb
Give a try to Mongo-hacker(node module), it alway prints pretty. https://github.com/TylerBrock/mongo-hacker
More it enhances mongo shell (supports only ver>2.4, current ver is 3.0), like
- Colorization
- Additional shell commands (count documents/count docs/etc)
- API Additions (db.collection.find({ ... }).last(), db.collection.find({ ... }).reverse(), etc)
- Aggregation Framework
I am using for while in production env, no problems yet.
Solution 7 - Mongodb
Got to the question but could not figure out how to print it from externally-loaded mongo. So:
This works is for console: and is prefered in console, but does not work in external mongo-loaded javascript:
db.quizes.find().pretty()
This works in external mongo-loaded javscript:
db.quizes.find().forEach(printjson)
Solution 8 - Mongodb
Check this out:
db.collection.find().pretty()
