At first, I didn’t understand how to use git worktrees, but now I find myself using it more and more for code reviews.

In this blog post, we’ll see how to use treesitter in neovim to automatically convert a JavaScript string into a template string if it contains ${.

Vim allows you to format text with an arbitrary external program with the :h gq operator. For example, say you want to format with prettier, you just need to set :h 'formatprg' option to npx prettier --stdin-filepath %, and gqip will format the paragraph with it (it also works if you select the text first and then use gq — vipgq).

The details HTML element doesn’t seem to work well when used as a controlled component in React, as pointed out in this open GitHub issue. At first, I thought it was a React bug, but at the end of my investigation while writing this, I concluded it’s simply a mistake — not having a single source of truth for state.

Forms are easy to get wrong with React because we can achieve their goal, which is to make a network request when on submission, with any arbitrary HTML and JavaScript.

In this post I want to share my favorite custom git commands — from aliases to shell scripts.

If there is one technology every developer has to deal with, no matter the stack, is the shell. But most do not bother learning it, so in this post we’ll dive deep into one of the most common shells, Bash, by comparing it with a more familiar programming language to most developers, JavaScript.

A dotfiles repo will help you manage configuration over time and synchronize them across machines, but it won’t help you with your dependencies — you still have to install git, tmux, vim, etc. Let’s see how Ansible can help with that.

I have recently started playing with Tailscale, and after a rough start I think I got the hang of it and wanna share how it improved some of my workflows like testing my blog on my Android device or connecting to it with adb without a USB cable.

This is the story about how I’m moving away from a tiling window manager, dwm, to a full-blown desktop environment, GNOME. It’s hardly an interesting story, but I feel like writing about it.

git rebase is a command for rewriting history, which sure seems scary at first but you’ll learn to love it.

The integration between Storybook and Mock Service Worker enables you to develop components isolated from your app and your back-end server.

adb is a CLI that lets you control your Android device from your computer. In this post I want to share its features that made me enjoy more mobile development.

How to use Node instead of jq for trivial property accessors.

In this post, I want to share how I started to change dwm source code in order to improve my experience with Android Emulator.

Vim has this well-known feature of opening the path under cursor with :h gf. This article explains well how this works.

Transforming SVG files into JSX is boring and prone to error. We can handle it better with svgr. Its defaults are good enough, but you’ll likely need to customize it for your needs, which is made possible by writing a template.

Take full advantage of Vim's shell integration and the quick fix list.

From the basic to the hacky stuff you should do to deliver the best experience.

Thoughts about writing integration tests for React apps, from react-testing-library to Cypress.

How and why to migrate a CRA project to Vite.

The way we’ll get this to work is by using a generic Language Server called efm-langserver, which is written in Go.

Getting Python syntax highlighting to work in Vim requires very little code, to my surprise.

The typical production-grade server used to deploy Python web apps, gunicorn, did not quite work for me. This post is the story of how I got it working.

I really like Vim’s :h errorformat feature, but only when I manage to get it right. Until then, I’m sure it will frustrate me more than once. It’s very awkward to write one if the program’s output you’re trying to capture is not trivial (e.g., LaTeX).

The :make command in Vim is quite useful, it runs whatever program is under the makeprg option and returns its output in the quickfix list, where you’ll be able to hop through the errors if they were parsed correctly by the errorformat option.

For those who find themselves in an environment which heavily relies on Excel and Salesforce, you may be interested in a way to automate the process of downloading reports from inside Excel with VBA only.
