This extension provides syntax highlighting for the experimental cpp2 language.

It support most of the pure-cpp2 grammar to date (new syntax since last version is still on-going).

It supports highlighting of plain C++ in cpp2 source code, but we have to mark the C++ block with a special comment:

/* lang:cpp */
int main() {
    return 0;
}
/* lang:end */

For any issues, please file them on the GitHub repo.

Build the extension

yarn install
yarn run build
yarn run package

The output VSIX file is located under cpp2.

Compile and run the test file

cppfront ./cpp2/test.cpp2 -import-std
clang++ -I../cppfront/source/ test.cpp -std=c++20 -o test.exe
./test.exe
