names

Random name generator tool that gives you Heroku or Docker-style names.

Usage

Simple! Run without any parameters, you get a name:

> names
selfish-change

Need more? Tell it how many:

> names 10
rustic-flag
nondescript-crayon
picayune-map
elderly-cough
skinny-jeans
neat-rock
aware-sponge
psychotic-coast
brawny-event
tender-oatmeal

Not random enough? How about adding a 4-number pad:

> names --number 5
imported-rod-9680
thin-position-2344
hysterical-women-5647
volatile-pen-9210
diligent-grip-4520

If you're ever confused, at least there's help:

> names --help
names 0.10.0

Author: Fletcher Nichol <fnichol@nichol.ca>

A random name generator with results like `delirious-pail'.

USAGE:
        names [FLAGS] [ARGS]

FLAGS:
    -h, --help       Prints help information
    -n, --number     Adds a random number to the name(s)
    -V, --version    Prints version information

ARGS:
    amount    Number of names to generate (default: 1)

Installation

GitHub releases

There are binary builds for Mac OS X (referred to as "Darwin") and Linux (a small, self-contained static binary) available through the project's GitHub releases.

Docker images

If Docker is more your speed, there's a speedy teeny tiny image (~1MB) on the Docker hub at fnichol/names. It's pretty easy to get started:

> docker run fnichol/names 4
furtive-polish
modern-business
alive-sun
tremendous-line

Building from source

If you want (or need) to build the CLI from source, the following should not take too long. Note that you'll need a version of Rust (and Cargo which ships with the Rust distributions) before running:

> git clone https://github.com/fnichol/names.git
> cd names/cli
> cargo build --release
# test it out
> ./target/release/names

A static binary on Linux?

This project was used by its author to experiment with producing static binaries on Linux from a Rust project that has no external dependencies. This was done using a special build of Rust that supports the musl libc project, available via the fnichol/rust:1.4.0-musl Docker image. Here's an example building the CLI to a static ELF binary on Linux:

> git clone https://github.com/fnichol/names.git
> cd names
> docker run --rm -ti -v `pwd`:/src -w /src/cli fnichol/rust:1.4.0-musl cargo build --release --target=x86_64-unknown-linux-musl

> docker run --rm -ti -v `pwd`:/src fnichol/rust:1.4.0-musl du -h ./cli/target/x86_64-unknown-linux-musl/release/names
1.5M    ./cli/target/x86_64-unknown-linux-musl/release/names

> docker run --rm -ti -v `pwd`:/src fnichol/rust:1.4.0-musl ldd ./cli/target/x86_64-unknown-linux-musl/release/names
        not a dynamic executable

> docker run --rm -ti -v `pwd`:/src fnichol/rust:1.4.0-musl file ./cli/target/x86_64-unknown-linux-musl/release/names
./cli/target/x86_64-unknown-linux-musl/release/names: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, BuildID[sha1]=6ad327ca3a5b21c42fa158832d89f6e9b0fc8e73, not stripped

A variant of this approach is used in the build_linux.sh script, which additional strips the binary and produces a Zip archive and SHA 256 checksum:

> git clone https://github.com/fnichol/names.git
> cd names
> ./cli/scripts/build_linux.sh 0.10.0

> du -h ./cli/target/x86_64-unknown-linux-musl/release/names
996K    ./cli/target/x86_64-unknown-linux-musl/release/names

> file ./cli/target/x86_64-unknown-linux-musl/release/names
./cli/target/x86_64-unknown-linux-musl/release/names: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, stripped

> du -csh ./cli/target/names*.zip*
396K    cli/target/names_0.10.0_linux_x86_64.zip
4.0K    cli/target/names_0.10.0_linux_x86_64.zip.sha256
