Function used to handle JavaScript exceptions in a JSCContext.

jsc_context_new ()

jsc_context_throw (JSCContext *context,
                   const char *error_message);

jsc_context_throw_with_name ()

void
jsc_context_throw_with_name (JSCContext *context,
                             const char *error_name,
                             const char *error_message);

Throw an exception to context using the given error name and message. The created JSCException can be retrieved with jsc_context_get_exception().

jsc_context_throw_with_name_printf ()

void
jsc_context_throw_with_name_printf (JSCContext *context,
                                    const char *error_name,

Throw an exception to context using the given error name and the formatted string as error message. The created JSCException can be retrieved with jsc_context_get_exception().

jsc_context_throw_exception ()

void
jsc_context_throw_exception (JSCContext *context,
                             JSCException *exception);

Throw exception to context .

jsc_context_clear_exception ()

void
jsc_context_clear_exception (JSCContext *context);

Clear the uncaught exception in context if any.

jsc_context_push_exception_handler ()

void
jsc_context_push_exception_handler (JSCContext *context,
                                    JSCExceptionHandler handler,
                                    gpointer user_data,
                                    GDestroyNotify destroy_notify);

Push an exception handler in context . Whenever a JavaScript exception happens in the JSCContext, the given handler will be called. The default JSCExceptionHandler simply calls jsc_context_throw_exception() to throw the exception to the JSCContext. If you don't want to catch the exception, but only get notified about it, call jsc_context_throw_exception() in handler like the default one does. The last exception handler pushed is the only one used by the JSCContext, use jsc_context_pop_exception_handler() to remove it and set the previous one. When handler is removed from the context, destroy_notify i called with user_data as parameter.

jsc_context_pop_exception_handler ()

void
jsc_context_pop_exception_handler (JSCContext *context);

Remove the last JSCExceptionHandler previously pushed to context with jsc_context_push_exception_handler().

jsc_context_get_current ()

JSCContext *
jsc_context_get_current (void);

Get the JSCContext that is currently executing a function. This should only be called within a function or method callback, otherwise NULL will be returned.

jsc_context_evaluate ()

JSCValue *
jsc_context_evaluate (JSCContext *context,
                      const char *code,
                      gssize length);

Evaluate code in context .

jsc_context_evaluate_with_source_uri ()

JSCValue *
jsc_context_evaluate_with_source_uri (JSCContext *context,
                                      const char *code,
                                      gssize length,
                                      const char *uri,
                                      guint line_number);

Evaluate code in context using uri as the source URI. The line_number is the starting line number in uri ; the value is one-based so the first line is 1. uri and line_number will be shown in exceptions and they don't affect the behavior of the script.

jsc_context_evaluate_in_object ()

JSCValue *
jsc_context_evaluate_in_object (JSCContext *context,
                                const char *code,
                                gssize length,
                                gpointer object_instance,
                                JSCClass *object_class,
                                const char *uri,
                                guint line_number,
                                JSCValue **object);

Evaluate code and create an new object where symbols defined in code will be added as properties, instead of being added to context global object. The new object is returned as object parameter. Similar to how jsc_value_new_object() works, if object_instance is not NULL object_class must be provided too. The line_number is the starting line number in uri ; the value is one-based so the first line is 1. uri and line_number will be shown in exceptions and they don't affect the behavior of the script.

jsc_context_check_syntax ()

JSCCheckSyntaxResult
jsc_context_check_syntax (JSCContext *context,
                          const char *code,
                          gssize length,
                          JSCCheckSyntaxMode mode,
                          const char *uri,
                          unsigned  line_number,
                          JSCException **exception);

Check the given code in context for syntax errors. The line_number is the starting line number in uri ; the value is one-based so the first line is 1. uri and line_number are only used to fill the exception . In case of errors exception will be set to a new JSCException with the details. You can pass NULL to exception to ignore the error details.

jsc_context_get_global_object ()

JSCValue *
jsc_context_get_global_object (JSCContext *context);

Get a JSCValue referencing the context global object

jsc_context_set_value ()

void
jsc_context_set_value (JSCContext *context,
                       const char *name,
                       JSCValue *value);

Set a property of context global object with name and value .

jsc_context_get_value ()

JSCValue *
jsc_context_get_value (JSCContext *context,
                       const char *name);

Get a property of context global object with name .

jsc_context_register_class ()

JSCClass *
jsc_context_register_class (JSCContext *context,
                            const char *name,
                            JSCClass *parent_class,
                            JSCClassVTable *vtable,
                            GDestroyNotify destroy_notify);

Register a custom class in context using the given name . If the new class inherits from another JSCClass, the parent should be passed as parent_class , otherwise NULL should be used. The optional vtable parameter allows to provide a custom implementation for handling the class, for example, to handle external properties not added to the prototype. When an instance of the JSCClass is cleared in the context, destroy_notify is called with the instance as parameter.
