📝 Walkthrough

Walkthrough

Adds a top-level CMake build and a minimal C++ entry point. The new CMakeLists.txt uses FetchContent to fetch/build tree-sitter (and python grammar), SDL3, imgui, and imnodes, then defines a Telescode executable from src/main.cpp. src/main.cpp provides an empty main and an extern for the Python grammar.

Changes

Cohort / File(s)	Summary
Build Configuration CMakeLists.txt	New top-level CMake project (C++17) using FetchContent to fetch/build: tree-sitter (lib), tree-sitter-python (static from parser.c/scanner.c, links to tree-sitter), SDL3 (static), imgui (static with SDL3/OpenGL3 backends), imnodes (static). Finds OpenGL and defines add_executable(Telescode ...) linking those targets.
Application Entry Point src/main.cpp	New minimal C++ entry file including SDL3/ImGui/imnodes/tree-sitter headers, declares extern "C" const TSLanguage *tree_sitter_python();, and defines int main() returning 0.
CI / Tooling Config .coderabbit.yaml	Updated reviews config shape: reviews.auto_review changed from boolean to object form with enabled: true and drafts: false.

✅ Passed checks (4 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title accurately describes the main changes: adding CMakeLists.txt and src/main.cpp files to set up the build system.
Description check	✅ Passed	The description follows the required template with all major sections completed: Summary, Changes, Related Issue, and Checklist all filled out appropriately.
Linked Issues check	✅ Passed	The PR successfully implements the requirements from issue #1: CMakeLists.txt with multi-dependency build configuration and src/main.cpp entry point are provided, supporting the specified cmake workflow.
Out of Scope Changes check	✅ Passed	All changes are directly related to issue #1 requirements. The .coderabbit.yaml update is a minor configuration adjustment unrelated to the core objective but not problematic.

_{✏️ Tip: You can configure your own custom pre-merge checks in the settings.}

CMakeLists.txt (1)

85-87: Consider making IMGUI_DEFINE_MATH_OPERATORS public for dependent targets.

IMGUI_DEFINE_MATH_OPERATORS is defined as PRIVATE on imnodes, but this macro affects ImGui's ImVec2/ImVec4 operator overloads. If code using imnodes (like src/main.cpp in future) also operates on ImGui math types, inconsistent definitions could cause ODR violations or compilation errors.

Consider defining it on the imgui target instead, where it applies to all ImGui consumers:

Suggested improvement

 target_link_libraries(imgui PUBLIC SDL3::SDL3-static)
+target_compile_definitions(imgui PUBLIC IMGUI_DEFINE_MATH_OPERATORS)
 
 # ── imnodes static library ────────────────────────────────────────────────────
 add_library(imnodes STATIC
     ${imnodes_SOURCE_DIR}/imnodes.cpp
 )
 target_include_directories(imnodes PUBLIC ${imnodes_SOURCE_DIR})
-target_compile_definitions(imnodes PRIVATE IMGUI_DEFINE_MATH_OPERATORS)
 target_link_libraries(imnodes PUBLIC imgui)

- Around line 8-11: Remove the invalid top-level reviews.drafts entry and keep
only the nested drafts under reviews.auto_review; specifically delete the legacy
"drafts: false" that sits directly under "reviews" and ensure "auto_review:
enabled: true / drafts: false" remains as the authoritative setting (look for
keys "reviews.drafts" vs "reviews.auto_review.drafts" in the diff and remove the
former).
