Syntax highlighting for C++ implementation headers, C++ module units, CMake scripts, and CMake cache files. This is a content-only plugin: it adds TextMate grammars and editor settings, with no background process or compiler integration.
| Files | Highlighting |
|---|---|
.ipp, .inl, .tpp, .tcc, .ixx, .cppm |
C++ inline/template implementations and module units |
CMakeLists.txt, .cmake |
CMake scripts |
CMakeCache.txt |
Cache keys, types, values, and help comments |
Ordinary .cpp, .cc, .hpp, and other built-in C++ associations remain with Orca's native support.
The C++ grammar uses the keyword, identifier, delimiter, number, string, comment, and annotation categories used by Monaco 0.55.1 C++. Standard library names and function names retain native identifier coloring. Modern keywords include module, import, concept, requires, consteval, and coroutine keywords. Numeric suffixes, digit separators, hexadecimal floats, prefixed raw strings, and complete multi-character operators are recognized. Colors come from the active Orca theme; TextMate and Monaco have different tokenization engines, so this is category alignment rather than a promise of identical parsing in every case.
CMake highlighting covers command calls, quoted and bracket arguments, bracket comments, recursive variable expansions (${PREFIX_${NAME}}), environment/cache variables, and nested generator expressions. Cache entries use a separate grammar rather than being interpreted as scripts.
This plugin does not provide semantic analysis, completion, debugging, build commands, or error diagnostics.
In Orca Settings → Plugins, install from this Git URL:

On the plugin page, the Create actions for C++ template example, C++ module example, and CMake script example open populated files in the active workspace. The same entries are available from the tab bar's + menu. The post-install Try it action uses the first example.
Orca's existing Try it buttons beside individual syntax contributions open empty files for typing. The host does not automatically load the samples/ directory for those buttons.
Examples are in samples. example.cmake is a runnable script (cmake -P samples/example.cmake); CMakeLists.txt is a highlighting fixture with illustrative target paths, not a complete project. CMakeCache.txt is sample data.
Use a regular installed copy for everyday editing. Development folders watch source changes and can reload open editors; unload them before checking a release.

orca plugin validate . --jsonTests run the grammars with TextMate and Oniguruma. They compare C++ keyword classifications and editor configuration with pinned Monaco 0.55.1, execute its actual Monarch tokenizer for include/attribute parity regressions, and exercise complete operators, numeric suffixes, multiline raw strings/comments, nested CMake expressions, cache entries, and populated examples. Development dependencies are not required to use the plugin.
