+#jq-console  
+  
+A jQuery terminal plugin written in CoffeeScript.  
+  
+This project was spawned because of our need for a simple web terminal plugin   
+for the <a href="http://repl.it">repl.it</a> project. It tries to simulate a low level terminal by providing (almost)  
+raw input/output streams as well as input and output states.  
+  
+Version 2.0 adds baked-in support for rich multi-line prompting and operation  
+queueing.
+  
+  
+##Tested Browsers  
+  
+The plugin has been tested on the following browsers:  
+  
+* IE 9+
+* Chrome 10+
+* Firefox 4+
+* Opera 11+
+* iOS 4+
+  
+  
+##Getting Started  
+  
+###Echo example
+
+```css
+    /* The console container element */
+    #console {
+      position: absolute;
+      width: 400px;
+      height: 500px;
+      background-color:black;
+    }
+    /* The inner console element. */
+    .jqconsole {
+        padding: 10px;
+    }
+    /* The cursor. */
+    .jqconsole-cursor {
+        background-color: gray;
+    }
+    /* The cursor color when the console looses focus. */
+    .jqconsole-blurred .jqconsole-cursor {
+        background-color: #666;
+    }
+    /* The current prompt text color */
+    .jqconsole-prompt {
+        color: #0d0;
+    }
+    /* The command history */
+    .jqconsole-old-prompt {
+        color: #0b0;
+        font-weight: normal;
+    }
+    /* The text color when in input mode. */
+    .jqconsole-input {
+        color: #dd0;
+    }
+    /* Previously entered input. */
+    .jqconsole-old-input {
+        color: #bb0;
+        font-weight: normal;
+    }
+    /* The text color of the output. */
+    .jqconsole-output {
+        color: white;
+    }
+```
+
+```html
+    <div id="console"></div>
+    <script src="jquery.js" type="text/javascript" charset="utf-8"></script>
+    <script src="jqconsole.js" type="text/javascript" charset="utf-8"></script>
+    <script>

+      });
+    </script>
+```

+
+* `div` is the div element or selector. Note that this element must be
+  explicity sized and positioned `absolute` or `relative`.
+* `welcomeString` is the string to be shown when the terminal is first rendered.  
+* `promptLabel` is the label to be shown before the input when using Prompt().  
+* `continueLabel` is the label to be shown before the continued lines of the  
+  input when using Prompt().
+
+##Configuration  
+  
+There isn't much initial configuration needed, because the user must supply  
+options and callbacks with each state change. There are a few config methods  
+provided to create custom shortcuts and change indentation width:  
+  
+###jqconsole.RegisterShortcut
+Registers a callback for a keyboard shortcut.
+Takes two arguments:  
+
+  * __(int|string)__ *keyCode*: The code of the key pressing which (when Ctrl is  
+    held) will trigger this shortcut. If a string is provided, the ASCII code  
+    of the first character is taken.  
+
+  * __function__ *callback*: A function called when the shortcut is pressed;  
+    "this" will point to the JQConsole object.  
+
+
+  Example:  
+
+        // Ctrl+R: resets the console.  
+        jqconsole.RegisterShortcut('R', function() {
+          this.Reset();  
+        });  
+
+###jqconsole.SetIndentWidth
+Sets the number of spaces inserted when indenting and removed when unindenting.  
+Takes one argument:  
+  
+  * __int__ *width*: The code of the key pressing which (when Ctrl is held) will  
+    trigger this shortcut.  
+
+
+  Example:  
+
+        // Sets the indent width to 4 spaces.  
+        jqconsole.SetIndentWidth(4);  
+
+###jqconsole.RegisterMatching 
+Registers an opening and closing characters to match and wraps each of the  
+opening and closing characters with a span with the specified class.  
+Takes one parameters:  
+
+  * __char__ *open*: The opening character of a "block".  
+  * __char__ *close*: The closing character of a "block".  
+  * __string__ *class*: The css class that is applied to the matched characters.  
+
+
+  Example:  
+
+        jqconsole.RegisterMatching('{', '}', 'brackets');
+  
+##Usage  
+  
+Unlike most terminal plugins, jq-console gives you complete low-level control  
+over the execution; you have to call the appropriate methods to start input  
+or output:  
+  
+###jqconsole.Input: 
+Asks user for input. If another input or prompt operation is currently underway,  
+the new input operation is enqueued and will be called when the current  
+operation and all previously enqueued operations finish. Takes one argument:  
+
+  * __function__ *input_callback*: A function called with the user's input when  
+    the user presses Enter and the input operation is complete.  
+
+
+  Example:  
+
+        // Echo the input.  
+        jqconsole.Input(function(input) {  
+          jqconsole.Write(input);  
+        });  
+
+
+###jqconsole.Prompt
+Asks user for input. If another input or prompt operation is currently underway  
+the new prompt operation is enqueued and will be called when the current  
+peration and all previously enqueued operations finish. Takes three arguments:  
+
+  * __bool__ *history_enabled*: Whether this input should use history. If true,  
+    the user can select the input from history, and their input will also be  
+    added as a new history item.  
+
+  * __function__ *result_callback*: A function called with the user's input when  
+    the user presses Enter and the prompt operation is complete.  
+
+  * __function__ *multiline_callback*: If specified, this function is called when  
+    the user presses Enter to check whether the input should continue to the  
+    next line. The function must return one of the following values:  
+
+      * `false`: the input operation is completed.  
+
+      * `0`: the input continues to the next line with the current indent.  
+
+      * `N` (int): the input continues to the next line, and the current  
+        indent is adjusted by `N`, e.g. `-2` to unindent two levels.  
+
+    
+  * __bool__ *async_multiline*: Whether the multiline callback function should  
+    be treated as an asynchronous operation and be passed a continuation  
+    function that should be called with one of the return values mentioned  
+    above: `false`/`0`/`N`.  
+
+
+  Example:  
+
+        jqconsole.Prompt(true, function(input) {  
+          // Alert the user with the command.  
+          alert(input);  
+        }, function (input) {  
+          // Continue if the last character is a backslash.  
+          return /\\$/.test(input);  
+        });  
+  
+###jqconsole.AbortPrompt 
+Aborts the current prompt operation and returns to output mode or the next  
+queued input/prompt operation. Takes no arguments.  
+
+  Example:  
+
+        jqconsole.Prompt(true, function(input) {  
+          alert(input);  
+        });  
+        // Give the user 2 seconds to enter the command.  
+        setTimeout(function() {  
+          jqconsole.AbortPrompt();  
+        }, 2000);  
+
+###jqconsole.Write
+Writes the given text to the console in a `<span>`, with an   
+optional class. If a prompt is currently being shown, the text is inserted  
+before it. Takes two arguments:  
+
+  * __string__ *text*: The text to write.  
+
+  * __string__ *cls*: The class to give the span containing the text. Optional.  
+
+  * __bool__ *escape*: Whether the text to write should be html escaped.  
+    Optional, defaults to true.  
+
+
+  Examples:  
+
+        jqconsole.Write(output, 'my-output-class')  
+        jqconsole.Write(err.message, 'my-error-class')  
+
+###jqconsole.Append
+Append the given node to the DOM. If a prompt is currently being shown, the
+text is inserted before it. Takes a single argument:
+
+   * __(string|Element)__ *node*: The DOM Element or html string to append to
+     the console just before the prompt.
+
+   Example:
+
+        // Add a div with the text 'hello' on a red background using jquery
+        jqconsole.Append($('<div>hello</div>').css('background-color', 'red'));
+
+        // We can also use document.createElement
+        node = document.createElement("div");
+        content = document.createTextNode("hello");
+        node.appendChild(content);

+##ANSI escape code SGR support
+
+jq-console implements a large subset of the ANSI escape code graphics.  
+Using the `.Write` method you could add style to the console using  
+the following syntax: 
+
+`ASCII 27 (decimal) or 0x1b (hex)`  `[`  `SGR code` `m`
+
+Example:
+
+    jqconsole.Write('\033[31mRed Text');
+
+Note that the third parameter `escape` must be true which defaults to it.
+
+You'll need to include the `ansi.css` file for default effects or create your  
+own using the css classes from the table below.

+##CSS Classes  
+  
+Several CSS classes are provided to help stylize the console:  
+  
+* `jqconsole`: The main console container.  
+* `jqconsole, jqconsole-blurred`: The main console container, when not in focus.  
+* `jqconsole-cursor`: The cursor.  
+* `jqconsole-header`: The welcome message at the top of the console.  
+* `jqconsole-input`: The prompt area during input. May have multiple lines.  
+* `jqconsole-old-input`: Previously-entered inputs.  
+* `jqconsole-prompt`: The prompt area during prompting. May have multiple lines.  
+* `jqconsole-old-prompt`: Previously-entered prompts.  
+* `jqconsole-composition`: The div encapsulating the composition of multi-byte  
+    characters.
+
+  
+Of course, custom classes may be specified when using `jqconsole.Write()` for  
+further customization.  
+

-
-3. Distribution Obligations.
-
-     3.1. Application of License.
-     The Modifications which You create or to which You contribute are
-     governed by the terms of this License, including without limitation
-     Section 2.2. The Source Code version of Covered Code may be
-     distributed only under the terms of this License or a future version
-     of this License released under Section 6.1, and You must include a
-     copy of this License with every copy of the Source Code You
-     distribute. You may not offer or impose any terms on any Source Code
-     version that alters or restricts the applicable version of this
-     License or the recipients' rights hereunder. However, You may include
-     an additional document offering the additional rights described in
-     Section 3.5.
-
-     3.2. Availability of Source Code.
-     Any Modification which You create or to which You contribute must be
-     made available in Source Code form under the terms of this License
-     either on the same media as an Executable version or via an accepted
-     Electronic Distribution Mechanism to anyone to whom you made an
-     Executable version available; and if made available via Electronic
-     Distribution Mechanism, must remain available for at least twelve (12)
-     months after the date it initially became available, or at least six
-     (6) months after a subsequent version of that particular Modification
-     has been made available to such recipients. You are responsible for
-     ensuring that the Source Code version remains available even if the
-     Electronic Distribution Mechanism is maintained by a third party.
-
-     3.3. Description of Modifications.
-     You must cause all Covered Code to which You contribute to contain a
-     file documenting the changes You made to create that Covered Code and
-     the date of any change. You must include a prominent statement that
-     the Modification is derived, directly or indirectly, from Original
-     Code provided by the Initial Developer and including the name of the
-     Initial Developer in (a) the Source Code, and (b) in any notice in an
-     Executable version or related documentation in which You describe the
-     origin or ownership of the Covered Code.
-
-     3.4. Intellectual Property Matters
-          (a) Third Party Claims.
-          If Contributor has knowledge that a license under a third party's
-          intellectual property rights is required to exercise the rights
-          granted by such Contributor under Sections 2.1 or 2.2,
-          Contributor must include a text file with the Source Code
-          distribution titled "LEGAL" which describes the claim and the
-          party making the claim in sufficient detail that a recipient will
-          know whom to contact. If Contributor obtains such knowledge after
-          the Modification is made available as described in Section 3.2,
-          Contributor shall promptly modify the LEGAL file in all copies
-          Contributor makes available thereafter and shall take other steps
-          (such as notifying appropriate mailing lists or newsgroups)
-          reasonably calculated to inform those who received the Covered
-          Code that new knowledge has been obtained.
-
-          (b) Contributor APIs.
-          If Contributor's Modifications include an application programming
-          interface and Contributor has knowledge of patent licenses which
-          are reasonably necessary to implement that API, Contributor must
-          also include this information in the LEGAL file.
-
-               (c)    Representations.
-          Contributor represents that, except as disclosed pursuant to
-          Section 3.4(a) above, Contributor believes that Contributor's
-          Modifications are Contributor's original creation(s) and/or
-          Contributor has sufficient rights to grant the rights conveyed by
-          this License.
-
-     3.5. Required Notices.
-     You must duplicate the notice in Exhibit A in each file of the Source
-     Code.  If it is not possible to put such notice in a particular Source
-     Code file due to its structure, then You must include such notice in a
-     location (such as a relevant directory) where a user would be likely
-     to look for such a notice.  If You created one or more Modification(s)
-     You may add your name as a Contributor to the notice described in
-     Exhibit A.  You must also duplicate this License in any documentation
-     for the Source Code where You describe recipients' rights or ownership
-     rights relating to Covered Code.  You may choose to offer, and to
-     charge a fee for, warranty, support, indemnity or liability
-     obligations to one or more recipients of Covered Code. However, You
-     may do so only on Your own behalf, and not on behalf of the Initial
-     Developer or any Contributor. You must make it absolutely clear than
-     any such warranty, support, indemnity or liability obligation is
-     offered by You alone, and You hereby agree to indemnify the Initial
-     Developer and every Contributor for any liability incurred by the
-     Initial Developer or such Contributor as a result of warranty,
-     support, indemnity or liability terms You offer.
-
-     3.6. Distribution of Executable Versions.
-     You may distribute Covered Code in Executable form only if the
-     requirements of Section 3.1-3.5 have been met for that Covered Code,
-     and if You include a notice stating that the Source Code version of
-     the Covered Code is available under the terms of this License,
-     including a description of how and where You have fulfilled the
-     obligations of Section 3.2. The notice must be conspicuously included
-     in any notice in an Executable version, related documentation or
-     collateral in which You describe recipients' rights relating to the
-     Covered Code. You may distribute the Executable version of Covered
-     Code or ownership rights under a license of Your choice, which may
-     contain terms different from this License, provided that You are in
-     compliance with the terms of this License and that the license for the
-     Executable version does not attempt to limit or alter the recipient's
-     rights in the Source Code version from the rights set forth in this
-     License. If You distribute the Executable version under a different
-     license You must make it absolutely clear that any terms which differ
-     from this License are offered by You alone, not by the Initial
-     Developer or any Contributor. You hereby agree to indemnify the
-     Initial Developer and every Contributor for any liability incurred by
-     the Initial Developer or such Contributor as a result of any such
-     terms You offer.
-
-     3.7. Larger Works.
-     You may create a Larger Work by combining Covered Code with other code
-     not governed by the terms of this License and distribute the Larger
-     Work as a single product. In such a case, You must make sure the
-     requirements of this License are fulfilled for the Covered Code.
-
-4. Inability to Comply Due to Statute or Regulation.
-
-     If it is impossible for You to comply with any of the terms of this
-     License with respect to some or all of the Covered Code due to
-     statute, judicial order, or regulation then You must: (a) comply with
-     the terms of this License to the maximum extent possible; and (b)
-     describe the limitations and the code they affect. Such description
-     must be included in the LEGAL file described in Section 3.4 and must
-     be included with all distributions of the Source Code. Except to the
-     extent prohibited by statute or regulation, such description must be
-     sufficiently detailed for a recipient of ordinary skill to be able to
-     understand it.
-
-5. Application of this License.
-
-     This License applies to code to which the Initial Developer has
-     attached the notice in Exhibit A and to related Covered Code.
-
-6. Versions of the License.
-
-     6.1. New Versions.
-     Netscape Communications Corporation ("Netscape") may publish revised
-     and/or new versions of the License from time to time. Each version
-     will be given a distinguishing version number.
-
-     6.2. Effect of New Versions.
-     Once Covered Code has been published under a particular version of the
-     License, You may always continue to use it under the terms of that
-     version. You may also choose to use such Covered Code under the terms
-     of any subsequent version of the License published by Netscape. No one
-     other than Netscape has the right to modify the terms applicable to
-     Covered Code created under this License.
-
-     6.3. Derivative Works.
-     If You create or use a modified version of this License (which you may
-     only do in order to apply it to code which is not already Covered Code
-     governed by this License), You must (a) rename Your license so that
-     the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",
-     "MPL", "NPL" or any confusingly similar phrase do not appear in your
-     license (except to note that your license differs from this License)
-     and (b) otherwise make it clear that Your version of the license
-     contains terms which differ from the Mozilla Public License and
-     Netscape Public License. (Filling in the name of the Initial
-     Developer, Original Code or Contributor in the notice described in
-     Exhibit A shall not of themselves be deemed to be modifications of
-     this License.)
-
-7. DISCLAIMER OF WARRANTY.
-
-     COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
-     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
-     WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF
-     DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
-     THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE
-     IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,
-     YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE
-     COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
-     OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
-     ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
-
-8. TERMINATION.
-
-     8.1.  This License and the rights granted hereunder will terminate
-     automatically if You fail to comply with terms herein and fail to cure
-     such breach within 30 days of becoming aware of the breach. All
-     sublicenses to the Covered Code which are properly granted shall
-     survive any termination of this License. Provisions which, by their
-     nature, must remain in effect beyond the termination of this License
-     shall survive.
-
-     8.2.  If You initiate litigation by asserting a patent infringement
-     claim (excluding declatory judgment actions) against Initial Developer
-     or a Contributor (the Initial Developer or Contributor against whom
-     You file such action is referred to as "Participant")  alleging that:
-
-     (a)  such Participant's Contributor Version directly or indirectly
-     infringes any patent, then any and all rights granted by such
-     Participant to You under Sections 2.1 and/or 2.2 of this License
-     shall, upon 60 days notice from Participant terminate prospectively,
-     unless if within 60 days after receipt of notice You either: (i)
-     agree in writing to pay Participant a mutually agreeable reasonable
-     royalty for Your past and future use of Modifications made by such
-     Participant, or (ii) withdraw Your litigation claim with respect to
-     the Contributor Version against such Participant.  If within 60 days
-     of notice, a reasonable royalty and payment arrangement are not
-     mutually agreed upon in writing by the parties or the litigation claim
-     is not withdrawn, the rights granted by Participant to You under
-     Sections 2.1 and/or 2.2 automatically terminate at the expiration of
-     the 60 day notice period specified above.
-
-     (b)  any software, hardware, or device, other than such Participant's
-     Contributor Version, directly or indirectly infringes any patent, then
-     any rights granted to You by such Participant under Sections 2.1(b)
-     and 2.2(b) are revoked effective as of the date You first made, used,
-     sold, distributed, or had made, Modifications made by that
-     Participant.
-
-     8.3.  If You assert a patent infringement claim against Participant
-     alleging that such Participant's Contributor Version directly or
-     indirectly infringes any patent where such claim is resolved (such as
-     by license or settlement) prior to the initiation of patent
-     infringement litigation, then the reasonable value of the licenses
-     granted by such Participant under Sections 2.1 or 2.2 shall be taken
-     into account in determining the amount or value of any payment or
-     license.
-
-     8.4.  In the event of termination under Sections 8.1 or 8.2 above,
-     all end user license agreements (excluding distributors and resellers)
-     which have been validly granted by You or any distributor hereunder
-     prior to termination shall survive termination.
-
-9. LIMITATION OF LIABILITY.
-
-     UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
-     (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
-     DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,
-     OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR
-     ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY
-     CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
-     WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
-     COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
-     INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
-     LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
-     RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
-     PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
-     EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO
-     THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
-
-10. U.S. GOVERNMENT END USERS.
-
-     The Covered Code is a "commercial item," as that term is defined in
-     48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
-     software" and "commercial computer software documentation," as such
-     terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48
-     C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995),

-     rights set forth herein.
-
-11. MISCELLANEOUS.
-
-     This License represents the complete agreement concerning subject
-     matter hereof. If any provision of this License is held to be
-     unenforceable, such provision shall be reformed only to the extent
-     necessary to make it enforceable. This License shall be governed by
-     California law provisions (except to the extent applicable law, if
-     any, provides otherwise), excluding its conflict-of-law provisions.
-     With respect to disputes in which at least one party is a citizen of,
-     or an entity chartered or registered to do business in the United
-     States of America, any litigation relating to this License shall be
-     subject to the jurisdiction of the Federal Courts of the Northern
-     District of California, with venue lying in Santa Clara County,
-     California, with the losing party responsible for costs, including
-     without limitation, court costs and reasonable attorneys' fees and
-     expenses. The application of the United Nations Convention on
-     Contracts for the International Sale of Goods is expressly excluded.
-     Any law or regulation which provides that the language of a contract
-     shall be construed against the drafter shall not apply to this
-     License.
-
-12. RESPONSIBILITY FOR CLAIMS.
-
-     As between Initial Developer and the Contributors, each party is
-     responsible for claims and damages arising, directly or indirectly,
-     out of its utilization of rights under this License and You agree to
-     work with Initial Developer and Contributors to distribute such
-     responsibility on an equitable basis. Nothing herein is intended or
-     shall be deemed to constitute any admission of liability.
-
-13. MULTIPLE-LICENSED CODE.
-
-     Initial Developer may designate portions of the Covered Code as
-     "Multiple-Licensed".  "Multiple-Licensed" means that the Initial
-     Developer permits you to utilize portions of the Covered Code under
-     Your choice of the NPL or the alternative licenses, if any, specified

- JSHINT is a global function. It takes two parameters.
-
-     var myResult = JSHINT(source, option);
-
- The first parameter is either a string or an array of strings. If it is a
- string, it will be split on '\n' or '\r'. If it is an array of strings, it
- is assumed that each string represents one line. The source can be a
- JavaScript text or a JSON text.
-
- The second parameter is an optional object of options which control the
- operation of JSHINT. Most of the options are booleans: They are all
- optional and have a default value of false. One of the options, predef,
- can be an array of names, which will be used to declare global variables,
- or an object whose keys are used as global names, with a boolean value
- that determines if they are assignable.
-
- If it checks out, JSHINT returns true. Otherwise, it returns false.
-
- If false, you can inspect JSHINT.errors to find out the problems.
- JSHINT.errors is an array of objects containing these members:
-
- {
-     line      : The line (relative to 0) at which the lint was found
-     character : The character (relative to 0) at which the lint was found
-     reason    : The problem
-     evidence  : The text line in which the problem occurred
-     raw       : The raw message before the details were inserted
-     a         : The first detail
-     b         : The second detail
-     c         : The third detail
-     d         : The fourth detail
- }
-
- If a fatal error was found, a null will be the last element of the
- JSHINT.errors array.
-
- You can request a Function Report, which shows all of the functions
- and the parameters and vars that they use. This can be used to find
- implied global variables and other problems. The report is in HTML and
- can be inserted in an HTML <body>.
-
-     var myReport = JSHINT.report(limited);
-
- If limited is true, then the report will be limited to only errors.
-
- You can request a data structure which contains JSHint's results.
-
-     var myData = JSHINT.data();
-
- It returns a structure with this form:
-
- {
-     errors: [
-         {
-             line: NUMBER,
-             character: NUMBER,

-JQuery Terminal Emulator is a plugin for creating command line interpreters in
-your applications. It can automatically call JSON-RPC service when user type
-commands or you can provide you own function in which you can parse user
-command. It's ideal if you want to provide additional functionality for power
-users. It can also be used to debug your aplication.
-
-Features:
-
-    * You can create interpreter for your JSON-RPC service with one line
-      of code.
-
-    * Support for authentication (you can provide function when user enter
-      login and password or if you use JSON-RPC it can automatically call
-      login function on the server and pass token to all functions)
-
-    * Stack of interpreters - you can create commands that trigger additional
-      interpreters (eg. you can use couple of JSON-RPC service and run them
-      when user type command)
-
-    * Command Tree - you can use nested objects. Each command will invoke a 
-      function, if the value is an object it will create new interpreter and
-      use function from that object as commands. You can use as much nested
-      object/commands as you like. If the value is a string it will create
-      JSON-RPC service.
-
-    * Support for command line history it use Local Storage if posible
-
-    * Support for tab completion if you create terminal from an object
-
-    * Include keyboard shortcut from bash like CTRL+A, CTRL+D, CTRL+E etc.
-
-    * Multiply terminals on one page (every terminal can have different
-      command, it's own authentication function and it's own command history)
-
-    * It catch all exceptions and display error messages in terminal
-      (you can see errors in your javascript and php code in terminal if they
-      are in interpreter function)
-      
-      
-Example of usage (javascript interpreter)
