vantage-repl-sandboxed

Advanced REPL extension for vantage.js

• regenerates the context each run / REPL start
• provides a sandbox with newly created context basics (see initCtx, allows these functions to be overwritten within sandbox)
• only options.context provided objects are really linked into the app
• sports developer console inspection (just type an object, function name, whatever an press enter)
• sports developer console syntax error output with position cursor
• validates and makes the position of the faulty javascript statement
• console.log/info/warn/error are also piped to a remote connection and do net mess up the prompt
• functions get highlighted if all optional dependencies are installed
• remote vantage connections do get the results there (v1.0.1)
• KNOWN: only single line statements are computed.

Bugs:

• '..' and '..-' execute on the main server instance. Ventage.exec does not execute in the remote shell, and there is no this.exec (nothing i can do about)

The banner shown above, when entering the REPL

node~$ js
 In REPL you can execute JS statements.
 * NodeJS module "Util" is loaded.
 * Set a new value on utilInspectDepth to increase inspection depth.
 *  -> utilInspectDepth=2;
 * You can use generic return functions to output any passed arguments (cbInfo/cbError, fnInfo/fnError)
 *  -> doSomething.success(cbInfo('success with:')).fail(cbError('failed with:'));
 *  -> doSomething.success(fnInfo).fail(fnError);
 *  -> mongo.db.users.find({}).exec(fnInfo);
 * Available objects:
 *  -> cbInfo:function(caption), cbError:function(caption), fnInfo:function(), fnError:function(), console:object,utilInspectDepth:number, koa:object, mongo:object, socketio:object, vantage:object
 **|Use "exit" or ".." to close the REPL. Use "..-" to exit completely.
