Plain-text view of stack traces at the top of HTML response, in a comment #32766
Description
(feature request)
Description
Symfony has a very nice and easy to use HTML view of exceptions. However, it is not unusual to see the HTML source of those pages dumped into a developer's console, for example as a result of interacting with the server using curl or any other console-based workflow. The stack trace is then hard to read as the dev has to skim past all the HTML.
My request is for a HTML comment to be included near the start of the page (I guess as high as possible without causing problems, which I think is directly under under the <meta charset="UTF-8" />) containing the stack trace in a plain text format. This would obviously be invisible when viewing the traces as intended in a browser, but would significantly increase reading speed at the console.
Example
After I've made a syntax error in my file AccountController.php, and then made a request with curl, the returned error page should be
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
