clojure.tools.analyzer

Takes a form and an env map and dispatches on the head of the form, that is a special form.

Given a form to analyze and an environment, a map containing: * :locals a map from binding symbol to AST of the binding value * :context a keyword describing the form's context from the :ctx/* hierarchy. ** :ctx/expr the form is an expression: its value is used ** :ctx/return the form is an expression in return position, derives :ctx/expr ** :ctx/statement the value of the form is not used * :ns a symbol representing the current namespace of the form to be analyzed returns an AST for that form. Every node in the AST is a map that is *guaranteed* to have the following keys: * :op a keyword describing the AST node * :form the form represented by the AST node * :env the environment map of the AST node Additionaly if the AST node contains sub-nodes, it is guaranteed to have: * :children a vector of the keys of the AST node mapping to the sub-nodes, ordered, when that makes sense It is considered a node either the top-level node (marked with :top-level true) or a node that can be reached via :children; if a node contains a node-like map that is not reachable by :children, there's no guarantee that such a map will contain the guaranteed keys.

Like analyze, but does not mark the form with :top-level true

Takes an env map and returns a function that analyzes a form in that env

Creates a var for sym and returns it

Returns an empty env

Repeatedly calls macroexpand-1 on form until it no longer represents a macro form, then returns it.

If form represents a macro form, returns its expansion, else returns form.

Multimethod that dispatches on op, should default to -parse

Set of special forms common to every clojure variant

Returns true if obj represent a var form as returned by create-var
