capture Reference

Store values to view or edit

capture

Description

Stores items in the order they are received for viewing, editing, and saving.

Examples

Collect numbers to paste into a table... or just to see what's been going on

Arguments

maximum [int]

Optional

The first argument sets a maximum number of items to store. If there is no argument, capture will store up to 512 items. Once the maximum has been exceeded, the earliest stored item is dropped as each new item is received.

display-format [symbol]

Optional

If the second argument is a, all items will be displayed in ASCII form in the editing window. If the second argument is x, all numbers will be displayed in hexadecimal form in the editing window. If the second argument is m, numbers less than 128 are displayed in decimal, and numbers greater than 128 are in hexadecimal. If there is no argument, all items are displayed in decimal.

Attributes

listout [int] (default: 0)

When enabled, the capture object will dump its contents as a list. Otherwise the object sends its contents one item at a time. Default = 0.

precision [int] (default: 4)

Floating-point precision to use when printing floating-point numbers to the capture object's window. Default = 4.

size [atom_long] (default: 512)

The maximum number of items which can be stored in the capture object's internal buffer. When resized, the object will attempt to retain the existing captured data. If the current capture position is already greater than the new size (if the buffer size is reduced), it will be reset to 0. Default = 512.

Common Box Attributes

Messages

int

Arguments

input [int]
Numbers or symbols are stored in the order in which they are received.

float

Arguments

input [float]
Numbers or symbols are stored in the order in which they are received.

list

Arguments

input [list]
All numbers and/or symbols in the list are stored in order from first to last.

anything

Arguments

input [list]
All numbers and/or symbols are stored in order from first to last.

clear

Erases the contents of a capture object.

count

Arguments

flag [int]
Sends the number of items collected since the last count message out the right outlet of the capture object. Upon receipt of the count message, the object's internal count will be reset to 0 unless flag is set.

(mouse)

Double-clicking on the object in a locked patcher will open a window which displays all values stored internally.

dump

Outputs the contents of the capture object, one item at a time, out the left outlet.

open

Causes the window associated with the capture object to become visible. The window is also brought to the front. Double-clicking on the capture object in a locked patcher has the same effect.

wclose

Closes the window associated with the capture object.

write

Arguments

filename [symbol]
The word write, followed by a symbol, saves the contents of the capture object into a text file, using the symbol as the filename.

Output

int

Out right outlet: The number of items received since last count message was received is sent out the right outlet in response to a count message.

int, float, symbol

Out left outlet: The captured contents are sent out the left outlet, one at a time, in response to the dump message.

Double-clicking on capture (when the patcher window is locked) opens an editing window in which the stored numbers can be viewed and edited. Editing the window does not actually alter the contents of capture, but is useful for cutting and pasting values into a table or a separate file. (Although capture can continue to store items while the editing window is open, the editing window is not updated. It must be closed and reopened to view the newly stored items.)
