What's New

v0.7 - Bug Fixes & Test Infrastructure

commits 76aaa44 - c8d8dab

• Key::ArrowRight == Key::None - fixed. Both were -999. None moved to -9999. Right arrow now works in keybindings.
• RenderBuf overflow - fixed. The char[4096] render buffer silently truncated on large terminals. Replaced with std::string that grows as needed.
• Action-not-found message - fixed. The error message was reading current_node->action after current_node was reset to root_node. Always printed nothing. Fixed by capturing the name first.
• Hardcoded default keybindings. The editor was a brick if keybinds.moon was missing. All standard Emacs bindings are now embedded in the binary. The file still overrides defaults on load.
• Block indent - implemented. Selecting lines and pressing Tab/ShiftTab now indents or dedents the whole block. Was a TODO before.
• gtest suites added covering GapBuffer (20 tests), UndoHistory (6), Config (8), KeyBinder (9), Input (7). See the Testing page for full docs.
• Test isolation fixed. Config tests now use a ConfigFileTest fixture with SetUp/TearDown. ScopedEnv RAII prevents env mutation from leaking between tests. TempFile validates writes.
• Added .clang-format (LLVM base, 4-space indent, 100 col).

v0.6 - The Honeymoon Massacre

138K → 81K uncompressed / 37K packed

• Binary size cut by 40% (73% with UPX LZMA). 81K raw, 37K packed.
• Zero heap allocations in the render loop. Replaced std::string output_buffer with a char[4096] stack buffer. The frame is built entirely on the stack, flushed in one write() syscall.
• Killed <fstream> entirely. All file I/O (4 files: buffer, config, keybinds, history) replaced with raw POSIX open/read/write/close. No more basic_filebuf vtables.
• std::map + std::function → enum + switch. Action dispatch is now a flat array lookup and a jump table. No red-black tree, no type-erased function wrappers.
• std::shared_ptr<KeyNode> → raw linked list. The key trie uses raw pointers. No atomic reference counting on every keystroke.
• <ranges> → manual loops. std::views::split / drop / take replaced with index arithmetic. 6K of <ranges> template instantiations removed from .text.
• std::string clipboard → char* + malloc. No SSO, no std::string copy/move overhead.
• std::vector<Key> → Key[16] + counter. Max keychord depth is 4. Why was this a vector.
• Vectors → constexpr C arrays. Menus, color tables, action names all baked into .rodata at compile time.
• std::stringstream → memchr + while loops. Config and keybind parsing now runs on raw char* buffers.
• <iostream> → write() syscalls. No locale init at startup. No static initializers.
• std::stoi + try/catch → strtol. No exception tables needed for parsing integers.
• Removed unused config fields: color_theme, scroll_offset, font_size (stored but never used) eliminated from the Config struct.

Flags used: -fno-exceptions, -fno-plt, -fno-rtti, -fno-unwind-tables, -fmerge-all-constants, -fno-unroll-loops, --icf=all, --hash-style=sysv, --gc-sections.

Sections eviscerated: .plt (624→20 bytes), .got.plt (328→20 bytes), .rela.plt (912→0 bytes), .gcc_except_table (3.4K→0 bytes), .eh_frame (5.5K→48 bytes).

v0.5 - Config Mixin, Undo/Redo & Working Settings

commit 6815087

• Extracted Config from a nested struct into a proper CRTP-compatible mixin (Editor : private Config, private UndoHistory<>)
• Settings persist to ~/.config/honeymoon/config.moon with XDG-aware path resolution and automatic directory creation
• Full key set (tab_width, show_line_numbers, syntax_highlighting, color_theme, scroll_offset, font_size) serializes as clean key value pairs with # comment support
• UndoHistory<> mixin brings snapshot-based undo/redo with contiguous-typing coalescing (typing gate so hello is one undo step)
• Every buffer-mutating path snapshots before touching state (cut, yank, kill_line, kill_word, transpose_chars/words, indent/dedent, delete_forward/backward, newline)
• Undo/redo applies via delete_range(0, size()) + insert_string (O(n) restore, O(1) snapshot)
• Bound C-/ → undo, M-/ → redo
• Settings screen actually works: arrow keys navigate, Enter toggles booleans, Tab Width cycles 2→4→8, and every change auto-saves

v0.4 - Tree-Sitter, Horizontal Scroll & Docs

commit 2721aac

• Tree-sitter syntax highlighting via dlopen at runtime (C, C++ grammars)
• Horizontal scrolling with gutter-aware offsets for line numbers
• transpose_words and dedent implemented (were stubs)
• New docs/updates.html changelog page
• Expanded internals.html with std::variant state machine and tree-sitter docs
• Editor screenshot on homepage
• Removed stale editor_test.hpp

v0.3 - Build Cleanup

commit a2a48ee

• Split build into cc_library (honeymoon_lib) + cc_binary
• Cleaned up .bazelrc with build presets: fast, release, debug, asan, ubsan, tsan
• Removed legacy WORKSPACE file, added MODULE.bazel.lock
• Added editor unit tests (886-line test header)
• Library enables testing and reuse without rebuilding the binary

v0.2 - Externalized Keybindings

commit c1c8afd

• Ripped all hardcoded keybindings out of editor.hpp
• Created keybinds.moon - all 50+ bindings in one config file
• Added M- prefix parsing (write M-w instead of Esc w)
• Trie-based key dispatch for multi-key chords (C-x C-s)
• ~60 lines of add_binding() calls removed from C++
• Bindings organized by category (movement, editing, file ops, search, etc.)
• Users can customize any keybinding without recompiling - just edit the file and restart

v0.1 - Bazel, Clang & C++23

commit f38c2e5

• Switched build system from Make/g++ to Bazel + Clang
• WORKSPACE, MODULE.bazel, BUILD, .bazelrc for Bazel 9
• C++23 enforced across the board via .bazelrc
• Refactored editor mode system from enum + if-else mess to std::variant + std::visit
• Adopted std::views::split for line rendering
• Fixed most-vexing-parse in Editor constructor (Clang strictness)
• Makefile still available as a fallback
