Alessandro De Blasis libghostty: add ghostty_free for cross-runtime memory safety 4mo ago

libghostty: add ghostty_free for cross-runtime memory safety On Windows, Zig's built-in libc and MSVC's CRT maintain separate heaps, so calling free() on memory allocated by the library causes undefined behavior. Add ghostty_free() that frees through the same allocator that performed the allocation, making it safe on all platforms. Update format_alloc docs and all examples to use ghostty_free() instead of free(). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

build: add CMake support for libghostty-vt Add a top-level CMakeLists.txt that wraps `zig build lib-vt` so that CMake-based downstream projects can consume libghostty-vt without needing to interact with the Zig build system directly. A custom command triggers the zig build during `cmake --build`, and the resulting shared library is exposed as an IMPORTED target. Downstream projects can pull in the library via FetchContent, which fetches the source and builds it as part of their own CMake build, or via find_package after a manual install step. The package config template in dist/cmake/ sets up the ghostty-vt::ghostty-vt target with proper include paths and macOS rpath handling. A c-vt-cmake example demonstrates the FetchContent workflow, creating a terminal, writing VT sequences, and formatting the output as plain text. CI is updated to auto-discover and build CMake-based examples alongside the existing Zig-based ones.

README.md

c-vt-cmake#

Demonstrates consuming libghostty-vt from a CMake project using FetchContent. Creates a terminal, writes VT sequences into it, and formats the screen contents as plain text.

Building#

cd example/c-vt-cmake
cmake -B build
cmake --build build
./build/c_vt_cmake

To build against a local checkout instead of fetching from GitHub:

cmake -B build -DFETCHCONTENT_SOURCE_DIR_GHOSTTY=../..
cmake --build build
