pac·apt·r, or the PACman AdaPTeR, is a wrapper for many package managers that allows you to use pacman commands with them.

Just set pacman as the alias of pacaptr on your non-Arch OS, and then you can run pacman -Syu wherever you like!

Why pacaptr?

Coming from Arch Linux to macOS, I really like the idea of having an automated version of Pacman Rosetta for making common package managing tasks less of a travail thanks to the concise pacman syntax.

That's why I decided to take inspiration from the existing sh-based icy/pacapt to make a new CLI tool in Rust for better portability (especially for Windows and macOS) and easier maintenance.

Supported Package Managers

pacaptr currently supports the following package managers (in order of precedence):

As for now, the precedence is still (unfortunately) hard-coded. For example, if both scoop and choco are installed, scoop will be the default. You can, however, edit the default package manager in your config.

Please refer to the compatibility table for more details on which operations are supported.


Note We need your help to achieve binary distribution of pacaptr on more platforms!


Tap Updated

brew install rami3l/tap/pacaptr


Scoop Version

scoop bucket add extras
scoop install pacaptr


Chocolatey Version Chocolatey Downloads

choco install pacaptr


Cargo Version Cargo Downloads

If you have installed cargo-binstall, the fastest way of installing pacaptr via cargo is by running:

cargo binstall pacaptr

To build and install the release version from crates.io:

cargo install pacaptr

To build and install the master version from GitHub:

cargo install pacaptr --git https://github.com/rami3l/pacaptr.git

For those who are interested, it is also possible to build and install from your local repo:

git clone https://github.com/rami3l/pacaptr.git && cd pacaptr
cargo install --path .
# The output path is usually `$HOME/.cargo/bin/pacaptr`.

To uninstall:

cargo uninstall pacaptr

For Alpine Linux users, cargo build might not work. Please try the following instead:

RUSTFLAGS="-C target-feature=-crt-static" cargo build

Packaging for Debian

cargo install cargo-deb
cargo deb


The config file path is defined with the following precedence:

  • $PACAPTR_CONFIG, if it is set;
  • $XDG_CONFIG_HOME/pacaptr/pacaptr.toml, if $XDG_CONFIG_HOME is set;
  • $HOME/.config/pacaptr/pacaptr.toml.

I decided not to trash user's $HOME without their permission, so:

  • If the user hasn't yet specified any path to look at, we will look for the config file in the default path.

  • If the config file is not present anyway, a default one will be loaded with Default::default, and no files will be written.

  • Any config item can be overridden by the corresponding PACAPTR_* environment variable. For example, PACAPTR_NEEDED=false is prioritized over needed = true in pacaptr.toml.

# This enforces the use of `install` instead of
# `reinstall` in `pacaptr -S`
needed = true

# Explicitly set the default package manager
default_pm = "choco"

# dry_run = false
# no_confirm = false
# no_cache = false



--using, --pm

Use this flag to explicitly specify the underlying package manager to be invoked.

# Here we force the use of `choco`,
# so the following output is platform-independent:
pacaptr --using choco -Su --dryrun
# Canceled: choco upgrade all

This can be useful when you are running Linux and you want to use linuxbrew, for example. In that case, you can --using brew.

Automatic sudo invocation

If you are not root and you wish to do something requiring sudo, pacaptr will do it for you by invoking sudo -S.

This feature is currently available for apk, apt, dnf, emerge, pkcon, port, xbps and zypper.

Extra flags support

The flags after a -- will be passed directly to the underlying package manager:

pacaptr -h
#     pacaptr [FLAGS] [KEYWORDS]... [-- <EXTRA_FLAGS>...]

pacaptr -S curl docker --dryrun -- --proxy=localhost:1234
# Canceled: foo install curl --proxy=localhost:1234
# Canceled: foo install docker --proxy=localhost:1234

Here foo is the name of your package manager. (The actual output is platform-specific, which largely depends on if foo can actually read the flags given.)

--dryrun, --dry-run

Use this flag to just print out the command to be executed (sometimes with a --dry-run flag to activate the package manager's dryrun option).

Pending means that the command execution has been blocked by a prompt; Canceled means it has been canceled in a dry run; Running means that it has started running.

Some query commands might still be run, but anything "big" should have been stopped from running, e.g. installation. For instance:

# Nothing will be installed,
# as `brew install curl` won't run:
pacaptr -S curl --dryrun
# Canceled: brew install curl

# Nothing will be deleted here,
# but `brew cleanup --dry-run` is actually running:
pacaptr -Sc --dryrun
# Running: brew cleanup --dry-run
# .. (showing the files to be removed)

# To remove the forementioned files,
# run the command above again without `--dryrun`:
pacaptr -Sc
# Running: brew cleanup
# .. (cleaning up)

--yes, --noconfirm, --no-confirm

Use this flag to trigger the corresponding flag of your package manager (if possible) in order to answer "yes" to every incoming question.

This option is useful when you don't want to be asked during installation, for example, but it can also be dangerous if you don't know what you're doing!

--nocache, --no-cache

Use this flag to remove cache after package installation.

This option is useful when you want to reduce Docker image size, for example.

Platform-Specific Tips

For brew

  • Please note that cask is for macOS only.

  • Be careful when a formula and a cask share the same name, e.g. docker.

    pacaptr -Si docker | rg cask
    # => Warning: Treating docker as a formula. For the cask, use homebrew/cask/docker
    # Install the formula `docker`
    pacaptr -S docker
    # Install the cask `docker`
    pacaptr -S homebrew/cask/docker
    # Make homebrew treat all keywords as casks
    pacaptr -S docker -- --cask

For scoop

  • pacaptr launches a pwsh subprocess to run scoop, or a powershell one if pwsh is not found in $PATH. Please make sure that you have set the right execution policy in the corresponding shell:

    Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

For choco

  • Don't forget to run in an elevated shell! You can do this easily with tools like gsudo.

For pip

  • Use pacaptr --using pip3 if you want to run the pip3 command.
