cljs.js

Each runtime environment provides various ways to eval JavaScript source. Whatever function *eval-fn* is bound to will be passed a map containing the following keys: :source - the source of the library (string) :name - used to unique identify the script (symbol) :cache - if the source was originally ClojureScript, will be given the analysis cache. The result of evaluation should be the return value.

Each runtime environment provides a different way to load a library. Whatever function *load-fn* is bound to will be passed two arguments - a map and a callback function: The map will have the following keys: :name - the name of the library (a symbol) :macros - modifier signaling a macros namespace load :path - munged relative library path (a string) It is up to the implementor to correctly resolve the corresponding .cljs, .cljc, or .js resource (the order must be respected). If :macros is true resolution should only consider .clj or .cljc resources (the order must be respected). Upon resolution the callback should be invoked with a map containing the following keys: :lang - the language, :clj or :js :source - the source of the library (a string) :file - optional, the file path, it will be added to AST's :file keyword (but not in :meta) :cache - optional, if a :clj namespace has been precompiled to :js, can give an analysis cache for faster loads. :source-map - optional, if a :clj namespace has been precompiled to :js, can give a V3 source map JSON If the resource could not be resolved, the callback should be invoked with nil.

Analyze ClojureScript source. The compiler state will be populated with the results of analyzes. The parameters: state (atom) the compiler state source (string) the ClojureScript source name (symbol or string) optional, the name of the source opts (map) compilation options. :eval - eval function to invoke, see *eval-fn* :load - library resolution function, see *load-fn* :source-map - set to true to generate inline source map information :def-emits-var - sets whether def (and derived) forms return either a Var (if set to true) or the def init value (if false). Defaults to false. :checked-arrays - if :warn or :error, checks inferred types and values passed to aget/aset. Logs for incorrect values if :warn, throws if :error. Defaults to false. :static-fns - employ static dispatch to specific function arities in emitted JavaScript, as opposed to making use of the `call` construct. Defaults to false. :fn-invoke-direct - if `true`, does not generate `.call(null...)` calls for unknown functions, but instead direct invokes via `f(a0,a1...)`. Defaults to `false`. :target - use `:nodejs` if targeting Node.js. Takes no other options at the moment. :ns - optional, the namespace in which to evaluate the source. :verbose - optional, emit details from compiler activity. Defaults to false. :context - optional, sets the context for the source. Possible values are `:expr`, `:statement` and `:return`. Defaults to `:expr`. cb (function) callback, will be invoked with a map. If successful the map will contain a key :value, the actual value is not meaningful. If unsuccessful the map will contain a key :error with an ex-info instance describing the cause of failure.

Compile ClojureScript source into JavaScript. The parameters: state (atom) the compiler state source (string) the ClojureScript source name (symbol or string) optional, the name of the source opts (map) compilation options. :eval - eval function to invoke, see *eval-fn* :load - library resolution function, see *load-fn* :source-map - set to true to generate inline source map information :def-emits-var - sets whether def (and derived) forms return either a Var (if set to true) or the def init value (if false). Default is false. :checked-arrays - if :warn or :error, checks inferred types and values passed to aget/aset. Logs for incorrect values if :warn, throws if :error. Defaults to false. :static-fns - employ static dispatch to specific function arities in emitted JavaScript, as opposed to making use of the `call` construct. Defaults to false. :fn-invoke-direct - if `true`, does not generate `.call(null...)` calls for unknown functions, but instead direct invokes via `f(a0,a1...)`. Defaults to `false`. :target - use `:nodejs` if targeting Node.js. Takes no other options at the moment. :ns - optional, the namespace in which to evaluate the source. :verbose - optional, emit details from compiler activity. Defaults to false. :context - optional, sets the context for the source. Possible values are `:expr`, `:statement` and `:return`. Defaults to `:expr`. cb (function) callback, will be invoked with a map. If successful the map will contain a key :value with the compilation result (string). If unsuccessful the map will contain a key :error with an ex-info instance describing the cause of failure.

Evaluate a single ClojureScript form. The parameters: state (atom) the compiler state form (s-expr) the ClojureScript source opts (map) compilation options. :eval - eval function to invoke, see *eval-fn* :load - library resolution function, see *load-fn* :source-map - set to true to generate inline source map information :def-emits-var - sets whether def (and derived) forms return either a Var (if set to true) or the def init value (if false). Default is false. :checked-arrays - if :warn or :error, checks inferred types and values passed to aget/aset. Logs for incorrect values if :warn, throws if :error. Defaults to false. :static-fns - employ static dispatch to specific function arities in emitted JavaScript, as opposed to making use of the `call` construct. Defaults to false. :fn-invoke-direct - if `true`, does not generate `.call(null...)` calls for unknown functions, but instead direct invokes via `f(a0,a1...)`. Defaults to `false`. :target - use `:nodejs` if targeting Node.js. Takes no other options at the moment. :ns - optional, the namespace in which to evaluate the source. :verbose - optional, emit details from compiler activity. Defaults to false. :context - optional, sets the context for the source. Possible values are `:expr`, `:statement` and `:return`. Defaults to `:expr`. cb (function) callback, will be invoked with a map. If successful the map will contain a key :value with the result of evalution. If unsuccessful the map will contain a key :error with an ex-info instance describing the cause of failure.

Evalute ClojureScript source given as a string. The parameters: state (atom) the compiler state source (string) the ClojureScript source name (symbol or string) optional, the name of the source opts (map) compilation options. :eval - eval function to invoke, see *eval-fn* :load - library resolution function, see *load-fn* :source-map - set to true to generate inline source map information :cache-source - optional, a function to run side-effects with the compilation result prior to actual evalution. This function takes two arguments, the first is the eval map, the source will be under :source. The second argument is a callback of one argument. If an error occurs an :error key should be supplied. :def-emits-var - sets whether def (and derived) forms return either a Var (if set to true) or the def init value (if false). Default is false. :checked-arrays - if :warn or :error, checks inferred types and values passed to aget/aset. Logs for incorrect values if :warn, throws if :error. Defaults to false. :static-fns - employ static dispatch to specific function arities in emitted JavaScript, as opposed to making use of the `call` construct. Defaults to false. :fn-invoke-direct - if `true`, does not generate `.call(null...)` calls for unknown functions, but instead direct invokes via `f(a0,a1...)`. Defaults to `false`. :target - use `:nodejs` if targeting Node.js. Takes no other options at the moment. :ns - optional, the namespace in which to evaluate the source. :verbose - optional, emit details from compiler activity. Defaults to false. :context - optional, sets the context for the source. Possible values are `:expr`, `:statement` and `:return`. Defaults to `:expr`. cb (function) callback, will be invoked with a map. If succesful the map will contain a :value key with the result of evaluation and :ns the current namespace. If unsuccessful will contain a :error key with an ex-info instance describing the cause of failure.
