Installation Guide

Check under Releases for Linux/Windows bundles and AppImages or visit our website .

Else, to build GNU Aris through source, follow the instructions given below. This should work on Linux, Mac or Windows (by using, for example, the MSYS2 toolchain and its MINGW64 environment):

Clone/Download the repository. For example:

   git clone https://github.com/kovzol/aris

You may need to install additional software like cmake, Qt, ninja, and of course, you need to have a working C/C++ compiler toolchain.

gtk version

Linux or Mac

1. Follow the steps:

   mkdir build
   cd build
   cmake ..

2. You should see something like this:

   -- The C compiler identification is GNU 11.3.0
   -- Detecting C compiler ABI info
   -- Detecting C compiler ABI info - done
   -- Check for working C compiler: /usr/bin/cc - skipped
   -- Detecting C compile features
   -- Detecting C compile features - done
   -- Found LibXml2: /usr/lib/x86_64-linux-gnu/libxml2.so (found version "2.9.13") 
   -- Found PkgConfig: /usr/bin/pkg-config (found version "0.29.2") 
   -- Checking for module 'gtk+-3.0'
   --   Found gtk+-3.0, version 3.24.33
   -- Configuring done
   -- Generating done
   -- Build files have been written to: /home/abc/workspace/aris/build/

3. Run the command make. You should see something like this at the end of the process:

   [ 88%] Building C object CMakeFiles/aris.dir/src/undo.c.o
   [ 92%] Building C object CMakeFiles/aris.dir/src/var.c.o
   [ 96%] Building C object CMakeFiles/aris.dir/src/vec.c.o
   [100%] Linking C executable aris
   [100%] Built target aris

4. Launch using ./aris.

For further instructions on building and installation (without cmake), refer to the INSTALL file.

Windows (with MINGW)

Run the following inside aris/:

mkdir build
cd build
cmake -G "MinGW Makefiles" ..
mingw32-make -j4

Snap Installation

To install GNU Aris through snap, visit https://snapcraft.io/aris and find the required distribution details according to your system.

qt version

Using cmake

Linux

Run the following inside aris/:

cmake -S qt/ -B build-qt/ -DCMAKE_GENERATOR:STRING=Ninja -DCMAKE_BUILD_TYPE:STRING=Release
cmake --build build-qt/ --target all

(In case Qt is installed in a non-system folder, add -DCMAKE_PREFIX_PATH=... to the first command line. See https://stackoverflow.com/a/66457331 for more information.)

This should generate a binary aris-qt inside build-qt/ , it can be run with ./aris-qt or you can install to /usr/local with:

cd build-qt/ && cmake -P cmake_install.cmake

To uninstall:

cd build-qt/ && xargs rm < install_manifest.txt

Using qmake

Run the following inside aris/ with appropriate path/to/qmake:

mkdir build-qt
cd build-qt
path/to/qmake -o Makefile ../qt/aris-qt.pro -spec linux-g++ CONFIG+=qtquickcompiler

This should generate a binary aris-qt inside build-qt/ , it can be run with ./aris-qt .

WebAssembly

To build to WebAssembly, Qt 6.5 and emscripten version 3.1.25 are required. Also, since emscripten doesn't have support for libxml2 yet, it would need to be compiled from source.

Follow these steps (after cloning libxml2) to compile libxml2 :

mkdir build
cd libxml2 && autoreconf -if -Wall
cd ../build 
path/to/emconfigure ../libxml2/configure --with-http=no --with-ftp=no --with-python=no --with-threads=no --enable-shared=no
path/to/emmake make
path/to/emar rcs libxml2.a *.o

Now, inside aris/ run the following:

mkdir libxml2
cp path/to/above/created/libxml2.a libxml2/
cp -r path/to/cloned-libxml2/include/libxml/ libxml2/

You can customize these paths by editing the aris-qt.pro file.

Finally:

mkdir build-wasm
cd build-wasm
/path/to/Qt/6.5.0/wasm_singlethread/bin/qmake /path/to/aris/qt/aris-qt.pro -spec wasm-emscripten && /usr/bin/make qmake_all
make -j $(nproc)

Now, run:

python -m http.server 8000

The project can be found at http://0.0.0.0:8000/ .

Contributing Guide

We welcome contributions to our project and thank you for taking the time to improve it. Here are some guidelines to follow when contributing:

Getting Started

Before contributing, please make sure to:

• Read the README file to understand the purpose and scope of the project.
• Look through the existing issues and pull requests to see if your contribution has already been addressed or discussed.
• If you're making significant changes or adding a new feature, consider opening an issue first to discuss it with the project maintainers.

How to Contribute

There are several ways to contribute to our project:

• Reporting Bugs: If you find a bug, please open an issue and describe the problem. Make sure to include steps to reproduce the issue and any error messages you receive regarding that issue.
• Fixing Bugs: If you'd like to fix a bug, please create a pull request with your changes. Make sure to include a description of the problem and how your changes will address it.
• Improving Documentation: If you notice any errors or omissions in the documentation, please create a pull request with your changes. Make sure to explain why the changes you made are necessary and how they can improve the documentation.

Report a Bug:

Please include enough information for the maintainers to reproduce the problem. Generally, that means:

• The contents of any input files necessary to reproduce the bug and command line invocations of the program(s) involved (very important!).
• A description of the problem and any samples of the erroneous output.
• The version number of the program(s) involved (use --version).
• Hardware, operating system, and compiler versions (uname -a).
• Unusual options you gave to configure, if any (see config.status).
• Anything else that you think would be helpful.
