# Indivisible
Indivisible is an optimized prime number generator and tester written in Rust.
Indivisible is an optimized prime number generator and tester.
## Build & Installation
To build the project you will require the Rust compiler and build
system, `cargo`. At which point you simply run `cargo build` in the root
directory of the project. To create an optimized release build append
the `--release` flag to the previous command.
Build a binary release using the following command:
Once a release build has been compiled, you may install Indivisible and
the manpage documentation by running the `install` script. In a similar
manner, you can run the `uninstall` script to remove the previously
installed binary and documentation.
```console
$ cargo build -r
```
## Usage
Once compiled, you can install it using the `install` script. By default this
will install to `/usr/local/{bin,share}`, but you can optionally change the
`PREFIX` used as follows:
The purpose of Indivisible is to find the nth prime and all the primes
before it. The basic usage is `indivisible <n>` where `n` is the ordinal
of the prime you'd like to find. To display all primes before `n`, you
can run verbose mode by using the `--verbose` or simply `-v` option.
```console
$ PREFIX="~/.local" ./install
```
Since Indivisible generates primes using previously computed primes, you
can also import prime numbers previously computed with the `--import` or
`-i` option. To store already computed primes you are expected to use
piping like any UNIX user would expect. Here is an example:
Additionally there is an `uninstall` script available. If you have used a custom
`PREFIX` this must also be specified to uninstall in the same manner. To see
where you've installed it you can always use the following command:
```bash
# store first 100 primes in ./primes
indivisible -v 100 > ./primes
# appends next 400 primes
indivisible -i ./primes -v 500 >> ./primes
# display the 600th prime
indivisible -i ./primes 600
```console
$ which indivisible
```
