A Modelica Compiler in Julia.
Please leave a star or make an issue to support the repository!
- Note that this package is still under development
Fetch all submodules:
git submodule update --init --recursive
Make sure that all submodules are on master
git submodule foreach "git checkout master && git pull"
- Go to ImmutableList.jl
- Dev it using the Julia package manager
- Go to MetaModelica.jl
- Dev it using the Julia package manager
- Go to Absyn.jl
Using same procedure as above for:
- ArrayUtil.jl
- ListUtil.jl Once this is done develop SCode and last but not least the DAE.
- Develop the OpenModelicaParser.jl
- Develop OMFrontend.jl
- Develop OMBackend.jl
- Develop the OM package
Since this is currently work in progress expect some warnings:)
To work with the package manager and manage dependencies of these packages you also need to add the OpenModelicaRegistry. To do this issue:
registry add https://github.com/JKRT/OpenModelicaRegistry.git
This will add this additional registry.
