# Radical Random Value Generator
|
||||
|
||||
```randical``` is a simple unix commandline utility to generate a series of
|
||||
random values of varying types. See below for usage and examples.
|
||||
|
||||
random values of varying types, with uniform distribution. See below for usage and examples.
|
||||
|
||||
|
||||
```text
|
||||
Radical Random Value Generator 1.61
|
||||
Generates arbitrary numbers of uniformly distributed random values.
|
||||
|
||||
USAGE:
|
||||
randical [FLAGS] [OPTIONS]
|
||||
|
||||
FLAGS:
|
||||
-e, --exit Randomly exit with either status 0, like /bin/true, or status 1, like /bin/false. Technically
|
||||
compatible with all other options, but doing so could obscure potential errors. Sets default number
|
||||
of values to print out to 0.
|
||||
--buel Prints either 'Here.' or 'Um, he's sick. My best friend's sister's boyfriend's brother's girlfriend
|
||||
heard from this guy who knows this kid who's going with the girl who saw Ferris pass out at 31
|
||||
Flavors last night. I guess it's pretty serious.', with equal probability. Not compatible with `-t`
|
||||
or `--bule`.
|
||||
--bule Prints either 'true' or 'false', with equal probability. Not compatible with `-t` or `--buel`.
|
||||
-e, --exit With equal probability, exit with either status 0, like /bin/true, or status 1, like /bin/false.
|
||||
Technically compatible with all other options, but exit status will have no relation to any
|
||||
generated output. Sets default number of values to print to 0.
|
||||
-h, --help Prints help information
|
||||
-V, --version Prints version information
|
||||
|
||||
OPTIONS:
|
||||
-n, --num-vals <NUM_VALS> Number of random values to print out. Defaults to 1.
|
||||
-t, --type <TYPE> Type of random value to print. Defaults to 'bool', with true represented as '1', and
|
||||
false as '0'.
|
||||
Possible values accepted are 'b'ool, 'f'loat64, 'u'nsigned64, and 's'igned64
|
||||
|
||||
-t, --type <TYPE> Type of random value to print. Defaults to 'bool', with true represented as 'Radical!',
|
||||
and false as 'Bogus.'.
|
||||
Possible values are 'b'ool, 'f'loat64, 'u'nsigned64, and 's'igned64
|
||||
```
|
||||
|
||||
Some examples:
|
||||
|
||||
``` text
|
||||

## What version is randical now?
|
||||
|
||||
See the ```VERSION``` file.
|
||||
Canonically, see the ```VERSION``` file. Heretically, now that there have been
|
||||
at least three releases, the version string in the ```Cargo.toml``` file will
|
||||
always be of the form "1.6.x", where *x* is at least one digit long, starting
|
||||
with "1". Each subsequent release will append the next digit of *phi* to
|
||||
*x*. The number of releases can be calculated by counting the number of digits
|
||||
in *x* and adding 2 to that.
