### Print

Category

Debugging

Function

Prints an object.

Syntax

    Print(object, options, component);

Inputs

Name | Type | Default | Description
--- | --- | --- | ---
`object` | object | none | object to print
`options` | string | "o" | printing options
`component` | string or string list | all components | component or components to print

Functional Details

This module prints `object` according to the specifications in `options`. Each character in the options string specifies printing a particular portion of the information about the object:

r | recursively traverse the object
o | print only the top level of the object
d | print first and last 25 items in arrays, as well as headers
D | print all the items in arrays as well as headers
x | for debugging, print in expanded form (lists the object address, the object tab, and the reference counts of the object)
n | print object to n levels.

The `component` parameter controls which components of `object` are printed. By default, all components are printed. All values are printed in decimal format except for byte array data, which are printed in hexadecimal.

In the user interface, the output of the Print module appears in the Message window.

Script Language Example

In the following example, the first call to Print does not recurse through the structure but simply reports (prints) that `both` is a group with two members. The second call recurses through the group and reports that each member of the group has six components, what those components are, and how many items there are in each. The third call provides this information and, in addition, the first and last 25 items in the "data" component of each field. The final call prints out all of the items in both the "positions" and "box" components.

    electrondensity = Import("/usr/local/dx/samples/data/watermolecule");
    electrondensity = Partition(electrondensity);
    iso1 = Isosurface(electrondensity,0.1);
    iso2 = Isosurface(electrondensity,0.3);
    both = Collect(iso1,iso2);
    Print(both);
    Print(both,"r");
    Print(both,"d", "data");
    Print(both,"D", {"positions", "box"});
