This package implements exceptions and errors with more details.

It provides a trait that can be used in exceptions or error classes in a way that can provide to applications more details about the circumstances that triggered those exceptions or classes.

Currently it can return a more helpful message about the errors, get snippets of the code that called the other code of the application that triggered the error, as well get a link to get more support for the code that caused the error.

Corner

Linux Build Status Latest Stable Version Latest Unstable Version License Downloads

PHP Exceptions and Errors designed to prevent your users from sharp corners. Inspired by Rust's helpful error messages.

  • Version 2.x: Requires PHP 7.1 or newer.
  • Version 1.x: Requires PHP 5.4 or newer.

Motivation

There are already libraries like Whoops which focus on taking existing uncaught Exceptions and giving them a user interface.

Rather than take control of your entire UI output, Corner extends the base Throwable interface and Exception/Error classes and makes them more useful even in non-UI contexts.

Corner's Extended Exception API

getHelpfulMessage()

> What exactly is going on here?

Imagine an email. Throwable::getMessage() can be likened to the subject line. In traditional exceptions, the closest thing you have to a message body is getTraceAsString().

In Corner, the "helpful message" is meant to be a full-text explanation of the problem. ASCII art diagrams (hard-coded or generated from the source code, if applicable) are permitted.

getSnippet($before = 0, $after = 0, $traceWalk = 0)

> What was the code surrounding the exception doing?

By default, this returns the line of PHP code that triggered the exception.

You can optionally pass a number of leading and trailing lines to this method to read more text from the source code file. The third argument allows you to excerpt snippets of code from within the stack trace.

The main use case for getSnippet() is to generate helpful error messages for getHelpfulMessage().

getSupportLink()

> Where can I find help?

The intent of this method is to give the developer using your project the quickest possible path to troubleshooting and solving the problem that they're most likely facing if this Exception / Error gets thrown.

If possible, link to a specific section of your project's documentation (including page anchors, if applicable) to get the developer closer to the solution to whatever problem they're encountering.
