compilex is a node.js library which is used to build online code editor/compiler websites and webservices.
and i'm planning to work on the jsMoule.js for supporting javascript
because that will simplify life for compilex users especially those who use all available languages and the choice of the language is done on the client side i think it's the most common use of compilex
and for separating the method with input, i found that it lead to very redundant code
auto detect the operating system and dropping the envData argument it can be done using process.platform, or using the os module for example
https://nodejs.org/api/process.html#process_process_platform
https://nodejs.org/api/os.html
sandbox the module because it's very vulnerable it's very easy for a client to compile a C code that contain a system("shutdown"); and shutdown the server and it can be worst
to run my server.js but it will be more simple if it was integrated to the compilex module or something like that
-another solution is to run the server.js in virtual machine but the same problem can happen and shutdown the virtual machine so i I thought about using a virtual machine for each client with virtualbox command line for example but that was more complicated
-and one more possible solution is to scan the client code and prevent the client from using system calls and from importing system libraries or any suspected library but that need a lot of work and and its depend on each language
it rely on the Error: stdout maxBuffer exceeded which i found very confusing because the maxBuffer attribute (in exec method) is the largest amount of memory available to stdout so we can clearly run a programme without infinite loops but if it's stdout exceed Maxbuffer compilex will console log "You might have initialized an infinite loop" which is not the case. and we can also compile a programme with a simple while(1){do nothing;} and without writing any thing in stdout in this case compilex will wait indefinitely for the programme to terminate without logging anything
i also thought about new powerful features :
more properties in the callback argument "data" beside data.error and data.output
for example data.memory Consumed and data.timeConsumed or data.cpuConsumed
data.otherStatistics
it can be done using addon like timemem.exe https://raw.githubusercontent.com/jafingerhut/clojure-benchmarks/master/bin/readme-timemem.txt
or using WMIC on windows
working on a programming competition platform for my university
after finishing it i will be honored to contribute to this project please let me know
Great insights @xnio94 . I started writing this library , when I barely know what node.js is during my college days . So , I have done a lot of mistakes in writing compilex. However , I managed it to do the basic stuff. You had almost mentioned all the shortcomings of the library , that I wanted to discuss. Next version would strive to overcome the challenges that we are facing right now.
You too had done a great job man . Your summarizes are really helpful. I will keep you updated with the library and Thanks once again man :+1:
I'am trying to implement the compilex project on my website...can i do it like this?
<html>
<head>
<script>
// POST
var code=$('#codeWritten').val();
var compiler = require('compilex');
var options = {stats : true}; //prints stats on console
compiler.init(options);
var envData = { OS : "windows"};
//else
var envData = { OS : "linux" }; // (Support for Linux in Next version)
compiler.compileJava( envData , code , function(data){
res.send(data);
});
// Delete temporary files
compiler.flush(function(){
console.log('All temporary files flushed !');
});
// GET
compiler.fullStat(function(data){
res.send(data);
});
</script>
</head>
<body>
<center>
<h1>Dylan Compiler</h1>
<form id="myform" name="myform" method="post" action="">
<h3>Code</h3>
<textarea id = 'codeWritten' rows="13" cols="100" id="code" name="code" ></textarea>
<br/>
<input type="submit" value="submit" name="submit" />

Hi everyone,
I tried and hosted the demo that is available in this link https://github.com/scriptnull/compilex/tree/master/examples
I am getting following error while running a java program with user input.
C:\zzz\zzz\Desktop\RunIT\node_modules\compilex\javaModule.js:143
fn(out)
^
TypeError: fn is not a function
at C:\zzz\zzz\Desktop\RunIT\node_modules\compilex\javaModule.js:143:12
Has anyone faced this error? or Am I doing something wrong?
