Functions

Function reference is split one page per package. Each function name in a package's table links to its own page, which has a fuller description and a runnable example you can evaluate in your browser. Cross-cutting topics have their own homes: the make-array/aref and hash-table operators are described under Arrays and Hash tables on the Data Types page, and each function's deviations from Common Lisp are noted on its own page.

Packages

Package	Functions
`cl`	The standard Common Lisp functions, used unqualified by `cl-user`
`rontolisp`	Implementation-specific functions: `version`, async HTTP fetch/serve, JSON, TCP/TLS sockets, the WASM/JVM export and WIT hooks
`linalg`	numpy-style vector/matrix operations
`torch`	A PyTorch-style tensor with automatic differentiation and an `nn`-style module layer
`java`	Java interop by reflection (JVM interpreter only)
`ffi`	C library interop
`objc`	The Objective-C runtime and AppKit through the foreign function API, with LispWorks' interface (macOS only)
`cocoa`	LispWorks' Foundation structures beside `objc` (macOS only)
`fli`	LispWorks' foreign objects and pointers beside `objc` (macOS only)
`appkit`	A Cocoa widget layer over `objc`
`checkpoint`	Stages a published model's tensors into packed float arrays: the half of reading a checkpoint that every file format shares
`safetensors`	Reads a Hugging Face `model.safetensors` -- or a sharded `model.safetensors.index.json` -- into packed float arrays
`geom`	Solid modeling over the `linalg` kernels
`tokenizer`	The byte-level and SentencePiece-style BPE a published language model ships with
`gguf`	Reads a GGUF checkpoint: the hyperparameters, the tokenizer and the weights in one file
`metal`	A Metal drawing surface on an `appkit` window over `objc`
`scene`	A 3-D viewer for `geom` solids over `metal`
`asdf`	A limited, API-compatible subset of ASDF system definitions
`uiop`	ASDF's portability layer -- 15 sub-packages, what is implemented, and the function tables
`ql` / `ql-dist`	A limited, API-compatible subset of Quicklisp
`usocket`	A usocket-compatible shim over the `rontolisp:tcp-*` built-ins
