Mongo Tabular

By example:

dev> db.survey.find()
{ "_cls" : "Survey", "_id" : ObjectId("50457507fe75bd7531268485"), "_types" : [ "Survey" ], "created" : ISODate("2012-09-04T03:27:03.161Z"), "description" : "lkjasd\r\n\r\ntext formatting", "owner" : ObjectId("503af0a3fe75bd735335a27b"), "questions" : [   {   "_types" : [    "Question" ],   "required" : false,     "label" : "How?",   "_cls" : "Question",    "label_text" : "",  "id" : "oLM8w83sTaXEm5RyZ6yQXNcjncn2pJHLyPFe9_7XKs",    "show_other" : false,   "type" : "textarea",    "options" : [ ] },  {   "_types" : [    "Question" ], "required" : true,    "label" : "Why?",   "_cls" : "Question",    "label_text" : "",  "id" : "gHFQdcvZB_ELF9Qp6liMwcAoX-eVDVHNAMcdDrwHCM",    "show_other" : false,   "type" : "text",    "options" : [ ] },  {   "_types" : [    "Question" ],   "required" : false,     "label" : "Who?",   "_cls" : "Question",    "label_text" : "",  "id" : "2sTKV2QipESmWrP4tcXb4TmECxf5p1Tf0bOD6-zJib",    "show_other" : false,   "type" : "select",  "options" : [   "Bananaphone",  "Watman",   "Yo Mama" ] },  {   "_types" : [    "Question" ],   "required" : false,     "label" : "Testing",    "_cls" : "Question",    "label_text" : "",  "id" : "TketUNiBTZkOJoj3K2tw74mS_l_p0bDPcIT1UeVMiI",    "show_other" : false,   "type" : "select",  "options" : [   "one",  "two",  "three" ] } ], "status" : "open", "title" : "My first survey" }
{ "_cls" : "Survey", "_id" : ObjectId("5068fcbefe75bd3063635bd6"), "_types" : [ "Survey" ], "created" : ISODate("2012-10-01T02:15:26.114Z"), "description" : "Just to test another one", "owner" : ObjectId("503af0a3fe75bd735335a27b"), "questions" : [    {   "_types" : [    "Question" ],   "required" : false,     "label" : "Why did the monkey?",    "_cls" : "Question",    "label_text" : "",  "id" : "tH3x9-t4T_8l6KiObYKJQ-07uPiKxZNqb_q4qKqbw4",    "show_other" : false,   "type" : "text",    "options" : [ ] },  {   "_types" : [    "Question" ],   "required" : false,     "label" : "Why didn't the monkey?",     "_cls" : "Question",    "label_text" : "",  "id" : "LeA-E_Sa3Tp2-dQdgJG3pk0qQy0gE-42E2fFKG6aya",    "show_other" : false,   "type" : "textarea",    "options" : [ ] } ], "status" : "open", "title" : "My second survey" }

What a mess to try and read. How about this:

dev> db.survey.find().t()
+--------------------------+----------+--------------+-------------------------------------+---------------------------------+--------------------------+---------------------------------------------------+--------+--------------------+

Grab mongorc.js, put it in $HOME/.mongorc.js. Start mongo. Call .t() on cursor objects (e.g. the return result of find()). You're welcome.

Improvements most welcome. Mongodb devs, plz consider something similar for upstream?

Options to .t()

You can pass .t() a hash with the following keys:

  • limit: Limits the number of rows in the output (which defaults to 20)
  • maxlen: Values longer than this will be truncated to this length, to prevent stupidly long output (default 50)
  • undef: A string representing what should be shown when a value is undefined for a given document
dev> db.survey.find().t({limit: 1, maxlen: 200})

Improving output formatting further

Observe that you can still pass useful things to .find(), for example to ditch columns from the output:

dev> db.survey.find(null, {questions: 0}).t({maxlen: 200})
+--------------------------+----------+--------------+-------------------------------------+---------------------------------+--------------------------+--------+--------------------+
|           _id            |   _cls   |    _types    |               created               |           description           |          owner           | status |       title        |
