How Flare's GitHub integration works under the hood

Apr 28th 2021 by Freek Van der Herten – 1 minute read

Last week, my colleague Ruben and I launched a major new feature at Flare: there's a new integration with GitHub that makes it possible to:

create a GitHub issue directly on a Flare error
associate a GitHub issue with a Flare error by mentioning a Flare URL in the GitHub issue
automatically resolve an error on Flare when you close the GitHub issue
automatically close a GitHub issue when you resolve an error in Flare

In this stream, Ruben and I will show you how you can use this integration and how it works under the hood.

The unreasonable effectiveness of print debugging

Apr 26th 2021 – buttondown.email

I do want to point out that print debugging has one critical feature that most step-based debuggers don't have: you can see program state from multiple time steps all at once.

Debug apps running on remote servers using Ray

Mar 8th 2021 by Freek Van der Herten – 1 minute read

Earlier this year, we released Ray, a desktop app that allows you to debug faster. Instead of dumping values to the browser or console, Ray allows you to display debugging information beautifully in a dedicated window.

Since launch, Ray helps you debug local projects. Today, we're adding the most requested feature to Ray: the ability to connect to remote servers. All output of the ray() call, will be sent securely from your remote server to the local app via SSH.

Using this feature, you can quickly investigate problems on your production servers that you are unable to recreate locally.

In this short video you'll see a quick demo!

I'm proud to announce the immediate release of Ray, a desktop app that vastly improves your debugging experience. Ray is a dedicated window to send dumped values to. It has a lot of features that help you find and fix bugs faster.

A better way to work with a backtrace in PHP

To get the backtrace in PHP, you can use the debug_backtrace function. By default, it can be hard to work with. Using our newly released spatie/backtrace package, this becomes much simpler.

Let's dive in!

How to check which version of PHP you are running

Mar 14th 2020 by Freek Van der Herten – 1 minute read

When working on open source code, I like using the latest version of PHP. When developers that are not on the latest version use the package, they might see syntax errors.

You might ask why Composer doesn't protect against this? When composer.json requires the latest version, how do devs, not on the latest version, can even install the package?

Well, there seemingly are a lot of people that only upgrade the PHP version on the command line. For handling web requests, they are unknowingly using an older version of PHP. Here's how to make sure you are on the latest version of PHP on both the CLI and for handling web requests.

Exceptional Exceptions

May 29th 2019 – engagor.github.io

At the Clarabridge Developers blog, Toon Daelman wrote a good post on how to improve your exceptions.

You've made it to this post thinking "Why do we still need to talk about Exceptions?". Well, they're used everywhere in OOP codebases, but sometimes they're used in a way that make debugging a bit difficult. Let's look at some ways to make debugging exceptions a bit more fun!

Laravel Telescope: Data too long for column ‘content’

Nov 4th 2018 – ma.ttias.be

Mattias explains a problem we recently encountered at Oh Dear with Telescope.

For Oh Dear!, we're using Laravel Telescope as a convenient way of tracking/displaying exceptions, runs, ... It stores its exceptions in the database, so you can easily view them again. It stores those in a TEXT field in MySQL, which is limited to 2^16 bytes, or 65536 bytes. Some of our exceptions tend to be pretty long, and they were hitting this limit.

When your Laravel project grows, so do the Laravel views. Sometimes it might be hard to figure out, which part of the output HTML was rendered using which template. With this package, you can take a peek into your Laravel views and find out which template is responsible for which part of the output HTML.

When empty is not empty

May 19th 2018 by Freek Van der Herten – 2 minute read

Recently when I was working on a project I got some strange results when using the empty function. Here's what I was debugging. I've simplified the code a bit to share with you. var_dump( $person->firstName, empty($person->firstName) ); This was the result: string(5) "Freek"…
