There's not much to this program. To greet the currently logged in user, run:

> fnichol-cime "$USER"
Hello, jdoe!

For more help and full usage, use the --help or -h flags:

> fnichol-cime --help


install.sh (Pre-Built Binaries)

An installer is provided at https://fnichol.github.io/fnichol-cime/install.sh which installs a suitable pre-built binary for common systems such as Linux, macOS, Windows, and FreeBSD. It can be downloaded and run locally or piped into a shell interpreter in the "curl-bash" style as shown below. Note that if you're opposed to this idea, feel free to check some of the alternatives below.

To install the latest release for your system into $HOME/bin:

> curl -sSf https://fnichol.github.io/fnichol-cime/install.sh | sh

When the installer is run as root the installation directory defaults to /usr/local/bin:

> curl -sSf https://fnichol.github.io/fnichol-cime/install.sh | sudo sh

A nightly release built from HEAD of the main branch is available which can also be installed:

> curl -sSf https://fnichol.github.io/fnichol-cime/install.sh \
    | sh -s -- --release=nightly

For a full set of options, check out the help usage with:

> curl -sSf https://fnichol.github.io/fnichol-cime/install.sh \
    | sh -s -- --help

GitHub Releasees (Pre-Built Binaries)

Each release comes with binary artifacts published in GitHub Releases. The install.sh program downloads its artifacts from this location so this serves as a manual alternative. Each artifact ships with MD5 and SHA256 checksums to help verify the artifact on a target system.

Docker Image

A minimal image ships with each release (including a nightly built version from HEAD of the main branch) published to Docker Hub. The entrypoint invokes the binary directly, so any arguments to docker run will be passed to the program. For example, to display the full help usage:

> docker run fnichol/fnichol-cime --help

Cargo Install

If Rust is installed on your system, then installing with Cargo is straight forward with:

> cargo install fnichol-cime

From Source

To install from source, you can clone the Git repository, build with Cargo and copy the binary into a destination directory. This will build the project from the latest commit on the main branch, which may not correspond to the latest stable release:

> git clone https://github.com/fnichol/fnichol-cime.git
> cd fnichol-cime
> cargo build --release
> cp ./target/release/fnichol-cime /dest/path/


This crate executes a highly specialized algorithm to dynamically generate a greeting in english to a given subject. It is serious business.


This crate is on crates.io and can be used by adding the crate to your dependencies in your project's Cargo.toml file:

fnichol-cime = { version = "0.7.0", default-features = false }

Note that the default features include dependencies which are required to build a CLI and are not needed for the library.


Example: greeting a human

Assuming we have a human named Jane:

let greeting = fnichol_cime::greeting("Jane");
// #=> "Hello, Jane!"
