Friendly Interactive Shell and Expressive Programming Language

Elvish: Expressive Programming Language + Versatile Interactive Shell

Elvish is an expressive programming language and a versatile interactive shell, combined into one seamless package. It runs on Linux, BSDs, macOS and Windows.

Despite its pre-1.0 status, it is already suitable for most daily interactive use.

Building Elvish

Most users do not need to build Elvish from source. Prebuilt binaries for the latest commit are provided for Linux amd64, macOS amd64, Windows amd64 and many other platforms.

To build Elvish from source, you need

• A supported OS: Linux, {Free,Net,Open}BSD, macOS, or Windows 10.

  NOTE: Windows 10 support is experimental.

• Go >= 1.16.

To build Elvish from source, follow these steps:

# 1. Start from any directory you want to store Elvish's source code
# 2. Clone the Git repository
git clone https://github.com/elves/elvish
# 3. Change into the repository
cd elvish
# 4. Build and install Elvish
make get

This will install Elvish to ~/go/bin (or $GOPATH/bin if you have set $GOPATH). You might want to add the directory to your PATH.

To install it elsewhere, override ELVISH_MAKE_BIN in the make command:

make get ELVISH_MAKE_BIN=./elvish # Install to the repo root
make get ELVISH_MAKE_BIN=/usr/local/bin/elvish # Install to /usr/local/bin

Experimental plugin support

Elvish has experimental support for building and importing plugins, modules written in Go.

However, since plugin support relies on dynamic linking, it is not enabled in the official prebuilt binaries. You need to build Elvish from source, with ELVISH_PLUGIN_SUPPORT=1:

make get ELVISH_PLUGIN_SUPPORT=1

To build a plugin, see this example.
