MiniLua

MiniLua is a small lua interpreter that implements additional features like source location tracking. It is currently used in and developed for the interactive_script rqt plugin. The targeted lua-version is Lua 5.3

Building MiniLua

To build the project, you need to have 'nix' installed.

Make sure you cloned the repository with submodules (e.g. git clone --recurse-submodules [email protected]:sp-uulm/MiniLua.git) or if you already cloned the repository you need to fetch the submodules (e.g. git submodule update --init --recursive).

Now you can use it like any other CMake project:

mkdir build
cd build
cmake ..
make

Alternatively you can use the included scripts:

./scripts/setup_build.sh # will forward arguments to cmake
./scripts/build.sh # will forward arguments to make

Generating Documentation

The documentation uses Doxygen and the C++ Doxygen Theme of m.css. You need the doxygen command installed and you Python 3.6 as well as Jinja2 and Pygments installed:

# You may need sudo here
pip3 install jinja2 Pygments

To build the documentation you can simply run:

./scripts/docs.sh

You can now open build/docs/html/index.html in your browser and you should see the main page of the documentation.

Example Applications

There are two included example applications (possibly out of date). They can be found in the examples directory.

• MiniLua-cli: Executes some test strings.
• MiniLua-gui: Opens a window with an editor and a preview. The editor highlights positions that would be changed due to forcing the values. The preview is completely non-interactive.

For a more up-to-date example take a look at the interactive_script plugin for rqt.
