Install and manage multiple CHICKEN versions.
Dust is a binary-based CHICKEN version manager. It lets one quickly install multiple CHICKEN versions and switch between them.
The following platforms are supported:
More platforms may be added in the future, however this is not a priority. If you'd like support for a particular platform, please let the author know.
The following versions can be installed:
On Linux, you can download a precompiled version of the application:
wget -O dust https://foldling.org/dust/dust-$(uname -m)-linux chmod +x dust
Alternatively, you can build the program from source. This requires an existing CHICKEN version 5.0 or newer and the OpenSSL development libraries:
chicken-install -n dust
Dust operates in one of two modes. It can either install CHICKENs into a
system-wide installation directory (
/opt/dust) or into a user-specific
directory (specified by
In both cases, user files are isolated from one another, so this is
really just a question of where you want to put things. In the former
case, you'll need to initialise the installation directory by running
dust init (as root), while the latter can be used without root
Refer to the program's help text for a list of commands:
Usage: dust [--verbose] <command> ... status init <group> install [<name>] <version> switch <name> uninstall <name>
To install and activate to a particular version of CHICKEN, use
dust install 5.1.0 dust switch 5.1.0
You can use the
--verbose flag with the
install command to see some
status information during the installation.
You can also provide a name for an installed version, which allows you to have multiple instances of the same version installed at once:
dust install project-one 5.1.0 dust install project-two 5.1.0 dust switch project-one
To list available versions, use
status. To remove a version, use
dust uninstall project-two dust uninstall 5.1.0
You can also use Dust to install CHICKEN into a particular directory rather than the standard location. To do so, specify a pathname (including at least one slash):
dust install 5.1.0 ./some/path
This version is self-contained and
unmanaged in the sense that it
won't appear in
dust status, you can't
switch to it, and so on. To
use it, just invoke its programs directly:
Note that versions installed this way cannot be moved. If the path to an ad-hoc CHICKEN version changes, it will no longer work and you'll need to remove the directory and reinstall it.
