Terraform and OpenTofu version switcher written in Rust.

To install, simply run cargo install tfswitcher. There are also prebuilt binaries available with each release for Linux, macOS and Windows.

To see available flags and arguments, run tfswitcher -h or tfswitcher --help.

You can also use a configuration file to automatically set certain flags or arguments. Simply place a file called .tfswitch.toml either in your current working directory or in your $HOME directory.

bin = "/location/of/terraform/binary"
list_all = false
opentofu = false
version = "1.0.0"

tfswitcher can generate tab-completion scripts for your desired shell. To see which shells are supported, see the --help text.

For example, for Bash:

tfswitcher -c bash >> ~/.local/share/bash-completion/completions/tfswitcher

Alternatively, you can source the tab-completion script inside your shell's start up script:

echo "source <(tfswitcher -c bash)" >> ~/.bashrc

This has not been tested on Windows or macOS, so YMMV.

v0.1.0 used FFI with Cgo in order to use HashiCorp's terraform-config-inspect library. This was inadvertently published as the Windows and macOS builds were broken and is yanked.

v0.2.0 replaced the Go library with a partially-reimplemented Rust library to eliminate FFI and makes building for Windows and macOS a lot less painful.
