Debugging Neovim's Lua plugins

A solid selling point of Neovim is the ability to customize it to your heart's content. The standard way of doing that is via plugins written in Lua.
However, what happens if we encounter problems while customizing Neovim? For the cases where the answer can't even be found in the docs, we can still use the debugger!
In this video, I am walking you through the debugging process of Neovim's Lua plugins.

The Error object has a very useful property: the `stacktrace`. However, when dealing with asynchronous operations that end with errors (e.g. making an HTTP call), we might not have much useful information besides the error error message - the reason being the error occurred in a different context than the one where the asynchronous call was made from. If we want to be able to see the stacktrace...

A different approach to Journaling

Journaling is a habit I acquired a few years ago. Although it has indeed helped me in ways I might not fully realise, I decided to take a new approach that I feel it will help me even more. In this video, I discuss 'my new approach' and why I think it is better than the previous one. 💻 My journey in a written form: andreigatej.dev/ 💻 GitHub: github.com/Andrei0872 💻 Stack Overflow: stackoverflow...
