ArangoDB Shell Output

The ArangoDB shell will print the output of the last evaluated expressionby default:

  1. arangosh> 42 * 23

Show execution results

  1. 966

In order to prevent printing the result of the last evaluated expression,the expression result can be captured in a variable, e.g.

  1. arangosh> var calculationResult = 42 * 23

Show execution results

There is also the print function to explicitly print out values in theArangoDB shell:

  1. arangosh> print({ a: "123", b: [1,2,3], c: "test" });

Show execution results

  1. { 
  2.   "a" : "123", 
  3.   "b" : [ 
  4.     1, 
  5.     2, 
  6.     3 
  7.   ], 
  8.   "c" : "test" 
  9. }

By default, the ArangoDB shell uses a pretty printer when JSON documents areprinted. This ensures documents are printed in a human-readable way:

  1. arangosh> db._create("five")
  2. arangosh> for (i = 0; i < 5; i++) db.five.save({value:i})
  3. arangosh> db.five.toArray()

Show execution results

  1. [ArangoCollection 36779, "five" (type document, status loaded)]
  2. [ 
  3.   { 
  4.     "_key" : "36790", 
  5.     "_id" : "five/36790", 
  6.     "_rev" : "_ZHpY5sq--_", 
  7.     "value" : 2 
  8.   }, 
  9.   { 
  10.     "_key" : "36787", 
  11.     "_id" : "five/36787", 
  12.     "_rev" : "_ZHpY5sm--B", 
  13.     "value" : 1 
  14.   }, 
  15.   { 
  16.     "_key" : "36796", 
  17.     "_id" : "five/36796", 
  18.     "_rev" : "_ZHpY5sq--D", 
  19.     "value" : 4 
  20.   }, 
  21.   { 
  22.     "_key" : "36783", 
  23.     "_id" : "five/36783", 
  24.     "_rev" : "_ZHpY5sm--_",

While the pretty-printer produces nice looking results, it will need a lot ofscreen space for each document. Sometimes a more dense output might be better.In this case, the pretty printer can be turned off using the commandstop_pretty_print().

To turn on pretty printing again, use the start_pretty_print() command.
