MuJS

-
- - - -
- -

-MuJS is a lightweight Javascript interpreter designed for embedding in other -software to extend them with scripting capabilities. - -

-MuJS was designed with a focus on small size, correctness, and simplicity. -It is written in portable C and implements ECMAScript as specified by ECMA-262. -The interface for binding with native code is designed to be as simple as -possible to use, and is very similar to Lua. There is no need to interact with -byzantine C++ template mechanisms, or worry about marking and unmarking garbage -collection roots, or wrestle with obscure build systems. - -

-MuJS is developed and maintained by Artifex Software. -It was originally developed for use with the MuPDF viewer, but is designed to be useful as an independent component. - -

-The primary meeting place for the MuJS community is the -#mupdf -IRC channel on freenode. - -

-MuJS is free open source software distributed under the -ISC license. - -

MuJS Introduction

-
- - - -
- -

Why choose MuJS?

- -

Javascript is a proven scripting language

- -

-Javascript is one of the most popular programming languages in the world. -It is a powerful extension language, used everywhere on the web — both as -a way to add interactivity to web pages in the browser, and on the server side -with platforms like node.js. - -

-With MuJS you can bring this power to your application as well! - -

MuJS is standards compliant

- -

-MuJS implements ES5. -There are no non-standard extensions, so you can remain confident that -Javascript code that runs on MuJS will also run on any other standards -compliant Javascript implementation. - -

MuJS is portable

- -

-MuJS is written in portable C and can be built by compiling a single C file using any standard C compiler. -There is no need for configuration or fancy build systems. -MuJS runs on all flavors of Unix and Windows, on mobile devices (such as Android and iOS), -embedded microprocessors (such as the Beagle board and Raspberry Pi), etc. - -

MuJS is embeddable

- -

-MuJS is a simple language engine with a small footprint that you can easily embed into your application. -The API is simple and well documented and allows strong integration with code written in other languages. -You don't need to work with byzantine C++ templating mechanisms, or manually manage garbage collection roots. -It is easy to extend MuJS with libraries written in other languages. -It is also easy to extend programs written in other languages with MuJS. - -

MuJS is small

- -

-Adding MuJS to an application does not bloat it. -The source contains around 15'000 lines of C. -Under 64-bit Linux, the compiled library takes 180kB if optimized for size, -and 260kB if optimized for speed. - -Compare this with V8, SpiderMonkey or JavaScriptCore, -which are all several hundred thousand lines of code, -take several megabytes of space, -and require the C++ runtime. - -

MuJS is reasonably fast and secure

- -

-It is a bytecode interpreter with a very fast mechanism to call-out to C. -The default build is sandboxed with very restricted access to resources. -Due to the nature of bytecode, MuJS is not as fast as JIT compiling -implementations but starts up faster and uses fewer resources. -If you implement heavy lifting in C code, controlled by Javascript, -you can get the best of both worlds. - -

MuJS is free software

- -

-MuJS is free open source software distributed under the -ISC license. - -

MuJS is developed by a stable company

- -

-Artifex Software has long experience in -interpreters and page description languages, and has a history with open source -that goes back to 1993 when it was created to facilitate licensing Ghostscript -to OEMs. - -

MuJS Reference

-
- - - -
- -

Introduction

- -

-MuJS is a library, written in clean and simple C. -Being an extension library, MuJS has no notion of a main program: it only works embedded in a host client program. -The host program can invoke functions to execute Javascript code, read and write Javascript variables, and register C functions to be called by Javascript. - -

-The MuJS distribution includes a sample host program called "mujs", which uses the MuJS library to offer a standalone Javascript interpreter for interactive or batch use. - -

-This reference manual assumes that you are already familiar with the Javascript language, in particular the type system and object prototype mechanisms. - -

Basic Concepts

- -

Values and Types

- -

-There are six basic types in Javascript: undefined, null, boolean, number, string and object. - -

-Each object also has a class: object, array, function, userdata, regular expression, etc. - -

-Javascript can call functions written in C provided by the host program, as well as other Javascript functions. - -

-Objects with the userdata class are provided to allow arbitrary C data to be attached to Javascript objects. -A userdata object has a pointer to a block of raw memory, which is managed by the host. -Userdata values cannot be created or modified in Javascript, only through the C API. -This guarantees the integrity of data owned by the host program. - -

-Custom properties on userdata objects can be implemented using getter and setter property accessor functions. - -

-Numbers are represented using double precision floating point values. - -

-Strings in the C interface are zero-terminated byte arrays in WTF-8 encoding. -This allows both arbitrary 16-bit values (as required by Javascript) and also -extended code points for the full 21-bit Unicode range. -These extended characters will mostly work as expected in Javascript. - -

-If you have Javascript code that expects to work with UTF-16 surrogate pairs, -you will need to manually convert any extended characters to surrogate pairs -and back when passing strings between C and Javascript. - -

-The U+0000 character is encoded as the two-byte sequence , same as in -modified UTF-8. - -

Environments

- -

-Each function executes within an environment which defines which variables are accessible. -This is a chain of all environment records in scope, with the global environment at the top. -Each environment record in MuJS is represented as an object with the null prototype, including the global environment object. - -

-The registry is a hidden environment record which is only accessible to C. -This is where Javascript values and objects that should only be accessible to C functions may be stored. - -

Error Handling

- -

-All Javascript actions start from C code in the host program calling a function from the MuJS library. -Whenever an exception is thrown during the compilation or execution of Javascript, control returns to the host, which can take appropriate measures (such as printing an error message). -C code can also throw exceptions by calling functions to create an error object and return control to Javascript. - -

-Internally, MuJS uses the C longjmp facility to handle errors. -A protected environment uses setjmp to set a recovery point. -The try statement in Javascript creates such a recovery point, as does calling js_dostring, js_dofile, js_ploadstring, js_ploadfile, -js_pcall and js_pconstruct. - -

-When an error occurs or an exception is thrown from Javascript, it does a long jump to the most recent active recovery point. - -

-If an error occurs outside any protected environment, MuJS first calls the panic function and then calls abort, thus exiting the host application. -Your panic function can avoid this exit by never returning (for example by doing a long jump to your own recovery point outside MuJS). - -

Garbage Collection

- -

-MuJS performs automatic memory management using a basic mark-and-sweep collector. -Collection is automatically triggered when enough allocations have accumulated. -You can also force a collection pass from C. - -

-Userdata objects have an associated C finalizer function that is called when -the corresponding object is freed. - -

The Stack

- -

-MuJS uses a virtual stack to pass values to and from C. -Each element in this stack represents a Javascript value (null, number, string, etc). - -

-Whenever Javascript calls C, the called function gets a new stack. -This stack initially contains the this value and any arguments passed to the function. -When the C function returns, the top value on the stack is passed back to the caller as the return value. - -

-The stack values are accessed using stack indices. -Index 0 always contains the this value, and function arguments are index 1 and up. -Negative indices count down from the top of the stack, so index -1 is the top of the index and index -2 is the one below that. - -

The Application Program Interface

- -

State

- -
-typedef struct js_State js_State;
-
- -

-The interpreter state is bundled up in the opaque struct js_State. -This state contains the value stacks, protected environments, and environment records. - -

-js_State *js_newstate(js_Alloc alloc, void *context, int flags);
-
- -

-Create a new state using the allocator function and allocator context. -Pass NULL to use the default allocator. - -

-The available flags: - -

    -
  • JS_STRICT: compile and run code using ES5 strict mode. -
- -
-void js_freestate(js_State *J);
-
- -

-Destroy the state and free all dynamic memory used by the state. - -

Allocator

- -

-The interpreter uses a host provided function for all memory allocation needs: - -

-typedef void *(*js_Alloc)(void *memctx, void *ptr, int size);
-
- -

-When size is zero, the allocator should behave like free and return NULL. -When size is not zero, the allocator should behave like realloc. -The allocator should return NULL if it cannot fulfill the request. -The default allocator uses malloc, realloc and free. - -

Panic

- -
-typedef void (*js_Panic)(js_State *J);
-
-js_Panic js_atpanic(js_State *J, js_Panic panic);
-
- -Set a new panic function, and return the old one. - -

Report

- -
-typedef void (*js_Report)(js_State *J, const char *message);
-
-void js_setreport(js_State *J, js_Report report);
-
- -

-Set a callback function for reporting various warnings -and garbage collection statistics. - -

-The report function must not throw an exception -or call any other MuJS function except js_getcontext(). - -

Garbage collection

- -
-js_gc(js_State *J, int report);
-
- -

-Force a garbage collection pass. -If the report argument is non-zero, send a summary of garbage collection statistics to -the report callback function. - -

Loading and compiling scripts

- -

-A script is compiled by calling js_loadstring or js_loadfile. -The result of a successful compilation is a function on the top of the stack. -This function can then be executed with js_call. - -

-void js_loadstring(js_State *J, const char *filename, const char *source);
-void js_loadfile(js_State *J, const char *filename);
-
- -

-Compile the script and push the resulting function. - -

-int js_ploadstring(js_State *J, const char *filename, const char *source);
-int js_ploadfile(js_State *J, const char *filename);
-
- -Like js_loadstring/js_loadfile but in a protected environment. -In case of success, return 0 with the result as a function on the stack. -In case of failure, return 1 with the error object on the stack. - -

Calling functions

- -
-void js_call(js_State *J, int n);
-
- -

-To call a function, you must use the following protocol: -1) push the function to call onto the stack, -2) push the this value to be used by the function, -3) push the arguments to the function in order, -4) finally, call js_call with the number of arguments pushed in step 3. - -

-Pop the function, the this value, and all arguments; -execute the function; -then push the return value from the function. - -

-void js_construct(js_State *J, int n);
-
- -

-The construct function implements the 'new' expression in Javascript. -This is similar to js_call, but without pushing a this value: -1) push the constructor function to call onto the stack, -2) push the arguments to the constructor function in order, -3) finally, call js_construct with the number of arguments pushed in step 2. - -

-int js_pcall(js_State *J, int n);
-int js_pconstruct(js_State *J, int n);
-
- -

-Like js_call and js_construct but in a protected environment. -In case of success, return 0 with the result on the stack. -In case of failure, return 1 with the error object on the stack. - -

Script helpers

- -

-There are two convenience functions for loading and executing code. - -

-int js_dostring(js_State *J, const char *source);
-
- -

-Compile and execute the script in the zero-terminated string in source argument. -If any errors occur, call the report callback function and return 1. -Return 0 on success. - -

-int js_dofile(js_State *J, const char *filename);
-
- -

-Load the script from the file with the given filename, then compile and execute it. -If any errors occur, call the report callback function and return 1. -Return 0 on success. - -

Protected environments

- -

-The js_try macro pushes a new protected environment and calls setjmp. -If it returns true, an error has occurred. The protected environment has been popped -and the error object is located on the top of the stack. - -

-At the end of the code you want to run in the protected environment you must call -js_endtry in order to pop the protected environment. Note: you should not call -js_endtry when an error has occurred and you are in the true-branch of js_try. - -

-Since the macro is a wrapper around setjmp, the usual -restrictions apply. -Use the following example as a guide for how to use js_try: - -

-if (js_try(J)) {
-	fprintf(stderr, "error: %s", js_trystring(J, -1, "Error"));
-	js_pop(J, 1);
-	return;
-}
-do_some_stuff();
-js_endtry(J);
-
- -

-Most of the time you shouldn't need to worry about protected environments. -The functions prefixed with 'p' (js_pcall, js_ploadstring, etc) handle setting -up the protected environment and return simple error codes. - -

Errors

- -
-void js_throw(js_State *J);
-
- -

-Pop the error object on the top of the stack and return control flow to the most recent protected environment. - -

-void js_newerror(js_State *J, const char *message);
-void js_newevalerror(js_State *J, const char *message);
-void js_newrangeerror(js_State *J, const char *message);
-void js_newreferenceerror(js_State *J, const char *message);
-void js_newsyntaxerror(js_State *J, const char *message);
-void js_newtypeerror(js_State *J, const char *message);
-void js_newurierror(js_State *J, const char *message);
-
- -

-Push a new error object on the stack. - -

-void js_error(js_State *J, const char *fmt, ...);
-void js_evalerror(js_State *J, const char *fmt, ...);
-void js_rangeerror(js_State *J, const char *fmt, ...);
-void js_referenceerror(js_State *J, const char *fmt, ...);
-void js_syntaxerror(js_State *J, const char *fmt, ...);
-void js_typeerror(js_State *J, const char *fmt, ...);
-void js_urierror(js_State *J, const char *fmt, ...);
-
- -

-Wrapper to push a new error object on the stack using a printf formatting string and call js_throw. - -

Stack manipulation

- -
-int js_gettop(js_State *J);
-void js_pop(js_State *J, int n);
-void js_rot(js_State *J, int n);
-void js_copy(js_State *J, int idx);
-void js_remove(js_State *J, int idx);
-void js_insert(js_State *J, int idx);
-void js_replace(js_State* J, int idx);
-
- -

Comparisons and arithmetic

- -
-void js_concat(js_State *J);
-int js_compare(js_State *J, int *okay);
-int js_equal(js_State *J);
-int js_strictequal(js_State *J);
-int js_instanceof(js_State *J);
-
- -

-The equivalent of the '+', comparison, and instanceof operators. -The okay argument to js_compare is set to 0 if any of the values are NaN, otherwise it is set to 1. - - - -

-void js_pushnull(js_State *J);
-void js_pushboolean(js_State *J, int v);
-void js_pushnumber(js_State *J, double v);
-void js_pushstring(js_State *J, const char *v);
-void js_pushliteral(js_State *J, const char *v);
-
- -

-Push primitive values. -js_pushstring makes a copy of the string, so it may be freed or changed after passing it in. -js_pushliteral keeps a pointer to the string, so it must not be changed or freed after passing it in. - -

-int js_isdefined(js_State *J, int idx);
-int js_isundefined(js_State *J, int idx);
-int js_isnull(js_State *J, int idx);
-int js_isboolean(js_State *J, int idx);
-int js_isnumber(js_State *J, int idx);
-int js_isstring(js_State *J, int idx);
-int js_isprimitive(js_State *J, int idx);
-
- -

-int js_toint32(js_State *J, int idx);
-unsigned int js_touint32(js_State *J, int idx);
-short js_toint16(js_State *J, int idx);
-unsigned short js_touint16(js_State *J, int idx);
-const char *js_tostring(js_State *J, int idx);
-
- -

-Convert the value at the given index into a C value. -If the value is an object, invoke the toString and/or valueOf methods to do the conversion. - -

-The conversion may change the actual value in the stack! - -

-There is no guarantee that the pointer returned by js_tostring will be valid after -the corresponding value is removed from the stack. - -

-Note that the toString and valueOf methods that may be invoked by these functions -can throw exceptions. If you want to catch and ignore exceptions, use the following -functions instead. The 'error' argument is the default value that will be returned -if a toString/valueOf method throws an exception. - -

-int js_tryboolean(js_State *J, int idx, int error);
-double js_trynumber(js_State *J, int idx, double error);
-int js_tryinteger(js_State *J, int idx, int error);
