Automatically Access a JS/CSS File in the Developer Tools 'Sources' Section

I am aware that I can customize my own Panel in the Chrome Developer Tools, but I am curious if there is a way to click a button within my panel and have the Developer Tools open a particular script or stylesheet in the 'Sources' panel related to the page being inspected?

Although it is possible to manually open the file from the menu on the left, I am interested in creating a shortcut that would directly open a specific file for editing.

A new feature has been introduced called the openResource API:

chrome.devtools.panels.openResource(string url, integer lineNumber, function callback)

This functionality is outlined in the chrome.devtools documentation.

When using this API, you provide the absolute URL of the file to be examined, along with an optional line number and a callback function. It's important to note that the line numbering is 0-based within the API but 1-based in the user interface. For example, if you wish to view line 10 in the UI, you must pass 9 as the line number in the function call.

As of now, there is an error in the documentation regarding the callback function: it is triggered on both success and failure and accepts a single argument. This argument is an object containing information about the outcome.

If the operation is successful, you will receive the following response:

{
    code: "OK",
    description: "OK",
    details: []
}

In case of an error, you will receive the following (among other potential error scenarios):

{
    code: "E_NOTFOUND",
    description: "Object not found: %s",
    details: [
        "http://localhost/foo.js"
    ],
    isError: true
}
