# Alltogether: opening a JavaScript debugger within Oxygen [JS Operations](https://www.oxygenxml.com/doc/versions/23.1/ug-editor/topics/dg-default-author-operations.html#dg-default-author-operations__jsoperation) through inclusion
|
||||
|
||||
This rambling shows how a [debugger](../js-debugger) can be launched using an [inclusion](../js-include).
|
||||
# Options
|
||||
This rambling shows how to add functionalities to the [OptionStorage](https://www.oxygenxml.com/InstData/Editor/SDK/javadoc/ro/sync/ecss/extensions/api/OptionsStorage.html) mechanism.
|
||||
|
||||
## Installation
|
||||
|
||||
To do so:
|
||||
### 1) add the include() function to your commons.js file:
|
||||
|
||||
```javascript
|
||||
include = function (filepath, isAbsolute) {
|
||||
if (isAbsolute === undefined || isAbsolute == false) {
|
||||
filepath = Packages.ro.sync.ecss.extensions.commons.operations.CommonsOperationsUtil.expandAndResolvePath(authorAccess, filepath);
|
||||
}
|
||||
var text = new java.lang.String(java.nio.file.Files.readAllBytes(java.nio.file.Paths. get (java.net.URI(filepath))));
|
||||
text = String(text);
|
||||
eval(text);
|
||||
}
|
||||
```
|
||||
### 2) create a debugger.js file:
|
||||
```javascript
|
||||
startDebugger = function () {
|
||||
|
||||
var runnable = {
|
||||
run: function () {
|
||||
main.dispose();
|
||||
}
|
||||
}
|
||||
|
||||
|
||||
var context = Packages.org.mozilla.javascript.Context.getCurrentContext();
|
||||
// Within the current context...
|
||||
var contextFactory = context.getFactory();
|
||||
var scope = Packages.org.mozilla.javascript.tools.shell.Environment(runnable.__parent__);
|
||||
// and the scope of the runnable variable's parent ...
|
||||
var main = Packages.org.mozilla.javascript.tools. debugger.Main.mainEmbedded(contextFactory, scope, 'Debugger');
|
||||
// start a debugging session ...
|
||||
main.setExitAction(java.lang.Runnable(runnable));
|
||||
// , clean the resources at exit time...
|
||||
main.setVisible(true);
|
||||
// and make it visible/
|
||||
}
|
||||
```
|
||||
### 3) Use these functions in your doOperation() method:
|
||||
```javascript
|
||||
doOperation = function () {
|
||||
include('debugger.js');
|
||||
startDebugger();
|
||||
}
|
||||
```

||||
