Available Headers
Collections (fond/collections/)
Policy-based data structures with compile-time Ordered/Frozen variants:
- Set — unordered, ordered, frozen, frozen-ordered (policy-based)
- Map — same four variants via policies
- List / Tuple — mutable list + frozen tuple
- BloomFilter / BloomSet — probabilistic fast-negative-lookup set
- LRUCache — simpoo version wrapping Map
- RingBuffer — fixed-size circular buffer, compile-time sized
- Trie — prefix tree for string lookup and autocomplete
- BitFlag — type-safe enum-keyed bitset wrapper
- Arena — bump allocator for bulk allocation
- Pool — fixed-size typed object pool with freelist
- SparseSet — O(1) add/remove/contains with dense iteration
- DynStack — dynamic LIFO stack, doubles as a freelist
Collections Core (fond/collections/core/)
Composable low-level building blocks for high-performance data structures:
- OpenMap — open-addressing hash map with tombstones, node pool, intrusive LRU list
- IntrusiveList — doubly-linked list that doesn't own nodes
- NodePool — pre-allocated typed pool for ListNode-derived types
- HashUtils — probing, power-of-2 masking, hash mixing, load factor math
High-Performance (fond/collections/)
- FastLRU — LRU cache built on OpenMap (zero allocations per get/put)
Colors (fond/colors/)
- Color — RGBA color struct with conversions to ANSI, ImGui, uint32
- Palette — named color constants (single source of truth)
- ANSI — terminal color constants (constexpr, zero allocation)
- ImGui — ImVec4/ImU32 color constants (generated from palette)
Logger (fond/logger/)
- Compile-time configurable logging with function pointer dispatch
- ANSI color support, file output with rotation, buffer mode, callbacks
std::formattemplate overloads on all log methods
Info (fond/info/)
- ProjectInfo — version, exit codes, project metadata with pybind11 bindings
- VersionHelpers — version bump/parse utilities
MsgPack (fond/msgpack/)
- Binary serialization with
MSGPACK_DEFINEmacro (powered byFOND_FOR_EACH) - Packer, Unpacker, Python packer/unpacker variants
Lua (fond/lua/)
- Lua table serialization with
LUA_DEFINEmacro (powered byFOND_FOR_EACH)
Macros (fond/macros/)
- FOND_FOR_EACH — preprocessor for-each over variadic args (generated, up to 100 args)
Tools
- ByteBuffer — unified read/write byte buffer
- Timer — scoped timer with auto unit selection, lap times,
time_it()lambda - EpochTimestamp — configurable timestamp formatting
- KeyStore — file-backed key/value store using MsgPack
- Locking — mutex helpers (C and C++ variants)
