bool Mode

In bool mode, boolean values are generated. The format of the command is as follows:

randog bool [PROP_TRUE] [--fmt FORMAT] [common-options]

Arguments and Options

PROP_TRUE (optional, default=0.5):
- the probability of True.
--fmt FORMAT (optional):
- the output format written in format specification mini-language
common-options
- common options

Examples

The simplest example is the following, which outputs True or False with a 50% probability of each.

randog bool

You can specify the probability of True.

# output True with 80% probability and False with 20% probability
randog bool 0.8

Format: Lowercase or Numeric

It may be necessary to output in lower case, for example, if the output is to be processed by a program in another language. In that case, the desired format can be obtained by outputting in json format as follows:

# Output True or False
randog bool

# Output true or false
randog bool --json

If you want to make it numeric, you can use --fmt.

# Output 1 or 0
randog bool --fmt 1

Note

This takes advantage of the property that values of type bool are treated as integer values in some contexts.

Repeatedly Generate

Most likely, you will not be satisfied with just one generated, so you will probably want to output multiple times as follows:

# Repeat 10 times
randog bool -r 10

# Generate list which contains 10 values
randog bool -L 10
