Example Libghostty Projects

Each example is a standalone project with its own build.zig, build.zig.zon, README.md, and src/main.c (or .zig). Examples are auto-discovered by CI via example/*/build.zig.zon, so no workflow file edits are needed when adding a new example.

Adding a New Example

1. Copy an existing example directory (e.g., c-vt-encode-focus/) as a starting point.
2. Update build.zig.zon: change .name, generate a new unique .fingerprint value (a random u64 hex literal), and keep .minimum_zig_version matching the others.
3. Update build.zig: change the executable .name to match the directory.
4. Write a README.md following the existing format.

Doxygen Snippet Tags

Example source files use Doxygen @snippet tags so the corresponding header in include/ghostty/vt/ can reference them. Wrap the relevant code with //! [snippet-name] markers:

//! [my-snippet]
int main() { ... }
//! [my-snippet]

The header then uses @snippet <dir>/src/main.c my-snippet instead of inline @code blocks. Never duplicate example code inline in the headers — always use @snippet. When modifying example code, keep the snippet markers in sync with the headers in include/ghostty/vt/.

Conventions

• Executable names use underscores: c_vt_encode_focus (not hyphens).
• All C examples link ghostty-vt via lazyDependency("ghostty", ...).
• build.zig files follow a common template — keep them consistent.
