rbenv VS ohmyzsh

When I was technical blogging on how to learn from open-source code [1], I used it quite frequently to get unstuck and/or to figure out how to tease apart a large question into multiple smaller functions. For example, I had no idea how to break up this long `sed` command [2] into its constituent parts, so I plugged it into ChatGPT and asked it to break down the code for me. I then Googled the different parts to confirm that ChatGPT wasn't leading me astray.

If I had asked StackOverflow the same question, it would have been quickly closed as being not broadly applicable enough (since this `sed` command is quite specific to its use case). After ChatGPT broke the code apart for me, I was able to ask StackOverflow a series of more discrete, more broadly-applicable questions and get a human answer.

TL;DR- I quite like ChatGPT as a search engine when "you don't know what you don't know", and getting unblocked means being pointed in the right direction.

Let’s get started. I prefer to manage my Ruby installations on my development machine with chruby paired with ruby-install. Another outstanding set of tools is rbenv with ruby-build. I highly recommend installing Ruby with one of those two sets of tools. Follow the instructions on their project’s READMEs. For this article, I’ll be running Ruby (MRI) v3.3.0.

By setting up your environment in isolation, you can prevent yourself from a lot of issues when experimenting with code. It makes your code behave more predictable due to the defined state of the runtime environment you are working with. This article should provide you with enough information to get started, but obviously, there is a lot more power embedded in NVM, Virtual Environment and RBEnv. So make sure to check their documentation.

There is this good resource that also talk about different ruby version manager from the Rbenv repository. With some links to benchmarks of ASDF and Rbenv.

rbenv (my personal favorite)

One suggestion would be to setup your install based on a development environment using git and a Ruby version manager like rvm or rbenv to allows you to setup a user controlled gemset and execution path.

rbenv for Ruby

git clone https://github.com/rbenv/rbenv.git ~/.rbenv

On MacOS, I haven't had a problem with character encodings in the terminal in ruby for a while, but used to. When I used to, it had to do with how ruby had been installed, in particular that it needed to be compiled linking against an appropriate readline library. Are you trying to use the ruby that came with debian? You might have more luck installing ruby yourself, and using a ruby version manager. rbenv might be the simplest for you.

For my local machine, I use RVM (head). Other options are rbenv and asdf.

For Linux users, your default terminal is just fine. The only thing I would install is oh-my-zsh with the autocomplete plugin. For my Mac friends out there, iTerm is an amazing software that works well with oh-my-zsh as well.

If you are not using oh-my-zsh, you are missing out on some amazing plugins. One feature most people wish the terminal had is autocompletion. With the zsh-autosuggestions plugin, your terminal will autocomplete most commands and remember previous ones.

That’s the minimum terminal setup. You can modify the look and add plugins such as autocompletion to your terminal by installing ohmyzsh and using themes such as powerlevel10k. I am already using them.

Somewhat related is "Oh My ZSH!" which is basically zsh on steroids, it's always one of the first things I install on a new computer. It gives things like new colors, themes, plugins, and more. Highly recommend you check it out.

I had just gone through a fun tutorial for setting up oh-my-zsh with a nice color scheme from iterm2colorschemes.com and a decent prompt and I was wondering: can I make my oblique strategy look nice? how can you actually use the colors from your scheme in the output in your cli?

After this you going to visit Oh-My-Zsh which is where the magic will happen.

after automating my dotfiles, I want to automate my installations, after that I want to make my terminal easier to use so I add OMZ with many plugins, after that, I try to automate the backup of my setting on my Gnome but failed, then try using git-lfs for my big files but it turned out to be idiotic moves, bla bla bla many try and fail.
