getnim installs the Nim programming language from official downloads and sources, enabling you to easily switch between stable and development compilers.
The aim of this tool is two-fold:
- Provide an easy way to install the Nim compiler and tools.
- Manage multiple Nim installations and allow them to be selected on-demand.
To select the current
stable release of Nim:
$ getnim stable Installed component 'nim' Installed component 'nimble' Installed component 'nimgrep' Installed component 'nimpretty' Installed component 'nimsuggest' Installed component 'testament' Switched to Nim 1.0.0 $ nim -v Nim Compiler Version 1.0.0 [Linux: amd64]
To update to the latest
stable release of Nim:
$ getnim update stable
To display which versions are currently installed:
$ getnim show Selected: 1.6.6 Channel: stable Path: /home/xx/.getnim/toolchains/nim-1.6.6 Versions: #devel * 1.6.6 1.0.0 #v1.0.0
Versions can be selected via
getnim 1.6.6 or by branch/tag name via
getnim #devel (note that selecting branches is likely to require Nim to be bootstrapped which may be slow).
Extract the zip archive and run the
runme.bat script. Follow any on screen
prompts and enjoy your new Nim and getnim installation.
There is also a third-party project to provide an installer for getnim, you can find it here (note that this isn't vetted by the Nim team so you do so at your own risk).

Optional: You can specify the initial version you would like the
script to install by specifying the
How getnim works
Similar to the likes of
getnim is a
toolchain multiplexer. It installs and manages multiple Nim toolchains and
presents them all through a single set of tools installed in
nimble and other tools installed in
proxies that delegate to the real toolchain.
getnim then allows you
to change the active toolchain by reconfiguring the behaviour of the proxies.
The toolchains themselves are installed into
nim will execute the proxy in
in turn will run the compiler in
assuming that 1.0.0 was selected.
How toolchains are installed
getnim downloads and installs the official release
binaries on Windows and Linux. On other
platforms, the official source release
is downloaded and built. This operation is only performed once when a new
version is selected.
As official binaries are made available for more platforms,
install them accordingly.
|C compiler||Downloaded automatically||gcc/clang||gcc/clang|
|curl||N/A||Any recent version (※)||Any recent version|
* Many macOS dependencies should already be installed. You may need to install a C compiler however. More information on dependencies is available here.
※ Some users needed to install
libcurl4-gnutls-dev (see here)
Git is required when installing #HEAD or a specific commit of Nim. The
binary is optional but will allow getnim to download the smallest tarballs.
> getnim -h getnim: The Nim toolchain installer. Usage: getnim <version/path/channel> Example: getnim 1.0.0 Installs (if necessary) and selects version 0.16.0 of Nim. getnim stable Installs (if necessary) Nim from the stable channel (latest stable release) and then selects it. getnim #head Installs (if necessary) and selects the latest current commit of Nim. Warning: Your shell may need quotes around `#head`: getnim "#head". getnim ~/projects/nim Selects the specified Nim installation. getnim update stable Updates the version installed on the stable release channel. getnim versions [--installed] Lists the available versions of Nim that getnim has access to. Channels: stable Describes the latest stable release of Nim. devel Describes the latest development (or nightly) release of Nim taken from the devel branch. Commands: update <version/channel> Installs the latest release of the specified version or channel. show Displays the selected version and channel. show path Prints only the path of the current Nim version. update self Updates getnim itself. versions [--installed] Lists available versions of Nim, passing `--installed` only displays versions that are installed locally (no network requests). Options: -h --help Show this output. -y --yes Agree to every question. --version Show version. --verbose Show low (and higher) priority output. --debug Show debug (and higher) priority output. --noColor Don't colorise output. --getnimDir:<dir> Specify the directory where toolchains should be installed. Default: ~/.getnim. --nimbleDir:<dir> Specify the Nimble directory where binaries will be placed. Default: ~/.nimble. --firstInstall Used by install script.
