alter-var-root clj/s

(alter-var-root v f & args)

Atomically alters the root binding of sci var v by applying f to its current value plus any args.

binding clj/s macro

(binding bindings & body)

Macro for binding sci vars. Must be called with a vector of sci dynamic vars to values.

err clj/s

Sci var that represents sci's clojure.core/*err*

eval-string clj/s

(eval-string s)

(eval-string s opts)

Evaluates string s as one or multiple Clojure expressions using the Small Clojure Interpreter.

The map opts may contain the following:

• :bindings: a map of symbols to values, e.g.: {'x 1}. The symbols will acts as names bound to the corresponding values in the expressions.

• :namespaces: a map of symbols to namespaces, where a namespace is a map with symbols to values, e.g.: {'foo.bar {'x 1}}. These namespaces can be used with require.

• :allow: a seqable of allowed symbols. All symbols, even those brought in via :bindings or :namespaces have to be explicitly enumerated.

• :deny: a seqable of disallowed symbols, e.g.: [loop quote recur].

• :realize-max: integer; when provided, program may realize a maximum number of elements from sequences, e.g. (vec (range)) will throw for any number. This also applies to sequences returned from the expression to the caller.

• :preset: a pretermined set of options. Currently only :termination-safe is supported, which will set :realize-max to 100 and disallows the symbols loop, recur and trampoline.

• :features: when provided a non-empty set of keywords, sci will process reader conditionals using these features (e.g. #{:bb}).

future clj/s macro

(future & body)

Like clojure.core/future but also conveys sci bindings to the thread.

in clj/s

Sci var that represents sci's clojure.core/*in*

new-dynamic-var clj/s

(new-dynamic-var name)

(new-dynamic-var name init-val)

(new-dynamic-var name init-val meta)

Alpha! Same as new-var but adds :dynamic true to meta. API subject to change.

new-var clj/s

(new-var name)

(new-var name val)

(new-var name init-val meta)

Alpha! Returns a new sci var. API subject to change.

out clj/s

Sci var that represents sci's clojure.core/*out*

pmap clj

(pmap f coll)

(pmap f coll & colls)

Like clojure.core/pmap but also conveys sci bindings to the threads.

with-bindings clj/s macro

(with-bindings bindings-map & body)

Macro for binding sci vars. Must be called with map of sci dynamic vars to values. Used in babashka.

with-in-str clj/s macro

(with-in-str s & body)

Evaluates body in a context in which sci's in is bound to a fresh StringReader initialized with the string s.

with-out-str clj/s macro

(with-out-str & body)

Evaluates exprs in a context in which sci's out is bound to a fresh StringWriter. Returns the string created by any nested printing calls.
