Runtime library

The runtime builtins – the values bound in every module, which need no import – and the four library modules that ship with the package, imported as any Python module is. Every builtin name, layout, compile, and runtime, is listed on Builtin names.

Builtins

Page	Covers
Types and type predicates	Every bound type and the NAME? predicate bound with it
Operators	The arithmetic, bitwise, comparison, membership, and identity operators as functions
Functions	Every other runtime builtin: predicates, pairs, collection builders, calling, async, iteration, conversion, attributes, refs, compilation
Exceptions	The Koskari exception classes and their hierarchy; every Python exception type is bound too

A Python builtin that is not bound, such as pow or eval, is reached through (import builtins).

Detailed pages

Name	Does
compile	Compile a source form to an invokable expression without running it
evaluate	Compile a form if needed and run it in a namespace
get-compiler	The compiler that owns a namespace, for compiling into that module
macroexpand	Expand a form until its head is no longer a macro
macroexpand-1	One expansion step
apply-layout, apply-layouts	Expand a #block: cons through the layout handlers at run time, for filled quasiquote blocks
help	Documentation for a binding, through the pager
map, filter	The lazy iterators, which take Koskari callables directly and iterate from both sync and async consumers
getitem*, hasitem*	Nested item access and membership along a key path
getattr*, hasattr*	Nested attribute access and presence along a dotted path
build-slice	Construct a slice object, the runtime behind item-slice
koskari-vars	The calling Koskari frame’s namespace, or an object’s __dict__
on-demand?	Whether the current context is on the demand path, where a bare await is not allowed

Modules

Module	Provides
koskari.itertools	The itertools combinators in a form that accepts Koskari functions and Koskari sources
koskari.solve	amb, require, solve, and solve-first: nondeterministic search over delimited continuations
koskari.asyncio	run-process and ProcessResult, the subprocess pair behind the bash fence
koskari.assets	The packaged icon, as SVG or PNG bytes or a filesystem path
