features VS powerlevel10k

Dev Containers not only allow you to define which extensions should be installed and which configuration settings shall be set, but they also have something they call "Dev Container Features".

there are already built docker images for common development environment. You can either use one of them, or build one from Docker file. Using a pre-built dev container doesn't mean you are only limited to that image, because you can still add other tools, which they are called features to that image. For a list of the pre-built templates check here, and for the other features that you can add check this. You don't need a Docker file, unless you want to build your dev environment step by step.

This is actually very easy. I've implemented a number of tools like this publicly but the standard doesn't limit you to public stuff. I can't emphasize enough the amount of speed we gained when we implemented this standard. https://containers.dev/features

features: While you can add everything in Dockerfile for the build, there are already pre-configured features you can optionally add. You can find the complete list of the features at here. Some examples of those features are common utilities and tools like Azure CLI, GitHub CLI and Terraform, and languages like node.js, Java, .NET, Python, etc.

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.

I used ohmyzsh with powerlevel10k/powerlevel10k[0] for years though recently i've settled on fish [1]

[0] https://github.com/romkatv/powerlevel10k

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?

A more robust way to do this would be to add simple wrappers that clone any external Zsh plugins you use regularly and store them in your own $ZSH_CUSTOM. For example, you say you like Powerlevel10k, so make that an OMZ plugin:

Looks like PowerLevel10 theme for Zsh shell

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

Am i the only one who feels fish is not worth it despite of hype? Don't get me wrong. I think that fish is really good shell.

BUT...

After adding the following plugins to zsh(before you chime in, it's just adding these lines,not anything configuring much. also it auto bootstraps on new install), I found out that fish is no where near configured zsh.

1) https://github.com/zdharma-continuum/zinit (plugin manager)

2) https://github.com/zdharma-continuum/fast-syntax-highlightin...

3) https://github.com/zdharma-continuum/history-search-multi-wo...

4) https://github.com/zsh-users/zsh-autosuggestions

5) https://github.com/zsh-users/zsh-completions

6) https://github.com/Aloxaf/fzf-tab

7) any good shell prompt generator like https://github.com/romkatv/powerlevel10k

For example, I use fzf integration for tab completion. Fish's fzf integration is nowhere as good as that of zsh's. Also, posix compat and almost bash compat of zsh is plus.

I acknowledge that zsh isn't perfect shell either and I have tried and failed few times in past to switch to fish. If you provide me compelling reason/s to switch to fish, I am all ears.

To build upon that concept, you can even have your shell prompt display a symbol if you have a backgrounded job. I use https://github.com/romkatv/powerlevel10k and the background_jobs handles it for me.

I also use PowerLevel10k. Themes up your zsh to make it look nice, pretty customisable.
