This repository contains work in progress of a nim compiler with a dex backend.
DEX is the assembly language used by the dalvik virtual machine. In android system it is used to represent the bytecode produced by java compilers.
This is not the offical nim github page For the real nim-lang, please use link below
The DEX assembler that is being targeted.

The aims are currently humble, and consist of firstly compiling simple programs.
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][csources-repo] repository.
Next, to build from source you will need:
gcc 3.x/later or an alternative such as clang,
Visual C++ or Intel C++. It is recommended to use gcc 3.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). 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 mantainers: see packaging guidelines.
# step 1:
git clone https://github.com/nim-lang/Nim.git
cd Nim
# step 2 (posix) clones `csources.git`, bootstraps Nim compiler and compiles tools
sh build_all.sh
# step 2 (windows)
git clone --depth 1 https://github.com/nim-lang/csources.git
cd csources
# requires `gcc` in your PATH, see also https://nim-lang.org/install_windows.html
build.bat # x86 Windows
build64.bat # x86_64 Windows
cd ..
bin\nim c koch
koch boot -d:release
koch tools # Compile Nimble and other tools
# end of step 2 (windows)Finally, once you have finished the build steps (on Windows, Mac or Linux) you
should add the bin directory to your PATH.
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.rst file.
nimble is Nim's package manager. To learn more about it, see the
[nim-lang/nimble][nimble-repo] repository.
Bear in mind that this is work in progress, but the usage will be something along these lines.
bin/nim dex --skipcfg fib.nim
In order to get as few moving parts as possible the standard library is not included when build DEX for the time being.
Furthermore to get to the bare essentials --skipcfg is recommended. This to get the minimal surface for implementing the DEX backend.
Currently prints out a subset of the AST. More to come shortly!
The compiler and the standard library are licensed under the MIT license, except for some modules which explicitly state otherwise. As a result you may use any compatible license (essentially any license) for your own programs developed with Nim. You are explicitly permitted to develop commercial applications using Nim.
