Single value text

The value format-type encodes a single sample value in a human readable representation.

Note: It currently only supports encoding of samples with a single signal!

Implementation

The source code of the format-type is available here: https://github.com/VILLASframework/node/blob/master/lib/formats/value.cpp

Configuration

delimiter	string
real_precision	integer Default: 17 Output all real numbers with at most n digits of precision. The valid range for this setting is between 0 and 31 (inclusive), and other values result in an undefined behavior. By default, the precision is 17, to correctly and losslessly encode all IEEE 754 double precision floating point numbers.
ts_origin	boolean Default: true If set, include the origin timestamp in the output.
ts_received	boolean Default: true If set, include the received timestamp in the output.
sequence	boolean Default: true If set, include the sequence number in the output.
data	boolean Default: true If set, include the data in the output.
offset	boolean Default: true If set, include the offset between origin and received timestamp in the output.

Example Configuration

node/etc/examples/formats/value.conf

nodes = {
    node = {
        type = "file"
        uri = "/dev/null"

        format = {
            type = "value"

            real_precision = 5
        }
    }
