eval-formclj/s

(eval-form ctx form)

Evaluates form (as produced by parse-string or parse-next) in the context of ctx (as produced with init). To allow namespace switches, establish root binding of sci/ns with sci/binding or sci/with-bindings.

Evaluates form (as produced by `parse-string` or `parse-next`) in the

eval-stringclj/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:

  • :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.

  • :bindings: :bindings x is the same as :namespaces {'user x}.

  • :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].

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

  • :env: an atom with a map in which state from the evaluation (defined namespaced and vars) will be persisted for re-use over multiple calls.

  • :disable-arity-checks: disables arity checks for single-arity functions.

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

The map `opts` may contain the following:

- `: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`.

- `:bindings`: `:bindings x` is the same as `:namespaces {'user x}`.

- `: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]`.

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

- `:env`: an atom with a map in which state from the
evaluation (defined namespaced and vars) will be persisted for
re-use over multiple calls.

- `:disable-arity-checks`: disables arity checks for single-arity
functions.
