This repository contains the Nim compiler, Nim's stdlib, tools, and documentation. For more information about Nim, including downloads and documentation for the latest release, check out Nim's website or bleeding edge docs.
The compiler currently officially supports the following platform and architecture combinations:
Operating System | Architectures Supported |
---|---|
Windows (Windows XP or greater) | x86 and x86_64 |
Linux (most distributions) | x86, x86_64, ppc64, and armv6l |
Mac OS X (10.04 or greater) | x86, x86_64, ppc64, and Apple Silicon (ARM64) |
More platforms are supported, however, they are not tested regularly and they may not be as stable as the above-listed platforms.
Compiling the Nim compiler is quite straightforward if you follow these steps:
First, the C source of an older version of the Nim compiler is needed to
bootstrap the latest version because the Nim compiler itself is written in the
Nim programming language. Those C sources are available within the
nim-lang/csources_v2
repository.
Next, to build from source you will need:
gcc
5.x/later or an alternative such as clang
,
Visual C++
or Intel C++
. It is recommended to use gcc
5.x or
later.git
or wget
to download the needed source repositories.build-essential
package when using gcc
on Ubuntu (and likely
other distros as well).Windows Note: Cygwin and similar POSIX runtime environments are not supported.
Then, if you are on a *nix system or Windows, the following steps should compile
Nim from source using gcc
, git
, and the koch
build tool.
Note: The following commands are for the development version of the compiler. For most users, installing the latest stable version is enough. Check out the installation instructions on the website to do so: https://nim-lang.org/install.html.
For package maintainers: see packaging guidelines.
First, get Nim from GitHub:
git clone https://github.com/nim-lang/Nim.git
cd Nim
Next, run the appropriate build shell script for your platform:
build_all.sh
(Linux, Mac)build_all.bat
(Windows)Finally, once you have finished the build steps (on Windows, Mac, or Linux) you
should add the bin
directory to your PATH.
See also bootstrapping the compiler.
See also reproducible builds.
koch
is the build tool used to build various parts of Nim and to generate
documentation and the website, among other things. The koch
tool can also
be used to run the Nim test suite.
Assuming that you added Nim's bin
directory to your PATH, you may execute
the tests using ./koch tests
. The tests take a while to run, but you
can run a subset of tests by specifying a category (for example
./koch tests cat async
).
For more information on the koch
build tool please see the documentation
within the doc/koch.md file.
nimble
is Nim's package manager. To learn more about it, see the
nim-lang/nimble
repository.
This project exists thanks to all the people who contribute.
See detailed contributing guidelines. We welcome all contributions to Nim regardless of how small or large they are. Everything from spelling fixes to new modules to be included in the standard library are welcomed and appreciated. Before you start contributing, you should familiarize yourself with the following repository structure:
bin/
, build/
- these directories are empty, but are used when Nim is built.compiler/
- the compiler source code. Also includes plugins within compiler/plugins
.nimsuggest
- the nimsuggest tool that previously lived in the nim-lang/nimsuggest
repository.config/
- the configuration for the compiler and documentation generator.doc/
- the documentation files in reStructuredText format.lib/
- the standard library, including:
pure/
- modules in the standard library written in pure Nim.impure/
- modules in the standard library written in pure Nim with
dependencies written in other languages.wrappers/
- modules that wrap dependencies written in other languages.tests/
- contains categorized tests for the compiler and standard library.tools/
- the tools including niminst
(mostly invoked via
koch
).koch.nim
- the tool used to bootstrap Nim, generate C sources, build the website,
and generate the documentation.If you are not familiar with making a pull request using GitHub and/or git, please read this guide.
Ideally, you should make sure that all tests pass before submitting a pull request.
However, if you are short on time, you can just run the tests specific to your
changes by only running the corresponding categories of tests. CI verifies
that all tests pass before allowing the pull request to be accepted, so only
running specific tests should be harmless.
Integration tests should go in tests/untestable
.
If you're looking for ways to contribute, please look at our issue tracker.
There are always plenty of issues labeled Easy
; these should
be a good starting point for an initial contribution to Nim.
