marcel VS nvm

Marcel is one of the pipe-objects-instead-of-strings shells (https://marceltheshell.org).

Here's a blog post showing how to use marcel to generate graphs directly from the command line.

Check out marcel (https://marceltheshell.org). It's yet another pipe-objects-instead-of-strings shell (like nushell). Unlike nushell, you pipe Python values. Marcel has no sublanguages (like awk, sed, ...). Instead, when logic is needed, you write Python code, delimited by parens. So:

It is a useful correction. This project predates the release of the movie: https://github.com/geophile/marcel/commit/bb6adacbb6b3a683ce...

Check out marcel: https://marceltheshell.org, and https://github.com/geophile/marcel. Both marcel and nushell start with the idea of piping structured data instead of strings, which is incredibly powerful. (This also applies to osh. I am the author of osh and marcel.)

Marcel (and osh) rely on Python types and language where typical shells have sublanguages. So instead of awk or find and their sublanguages, you just use Python. Instead of piping strings, you pipe streams of Python values.

Marcel lets you use Python on the commmand line. It also has an API which allows you to use shell-like commands inside of Python programs.

I wrote a shell, marcel, that pipes Python values instead of strings: https://marceltheshell.org.

It also does the inverse, allowing you to run marcel commands from Python, e.g. https://www.marceltheshell.org/scripting-1

Check out my entry, marcel: https://marceltheshell.org.

E.g., find the newest vlc instance and kill it (a command that an acquaintance needs frequently, for some reason):

    ps | select (p: p.name == 'vlc') | sort (p: p.create_time) | tail 1 | (p: p.signal(9))

nvm - Node version manager

Node.js + Nvm - runtime for javascript without a browser

Install Node.js if it hasn't been installed. There are several ways to install Node.js. You may download the installer from the official website, or install it with tools like NVM. After installation, run this command to verify its installation.

Our server also needs Node.js to run our app. We could install the binary directly, but I prefer to use a tool called NVM, which allows us to easily manage Node versions. We can install it with this command:

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.

I highly recommend setting up nodejs with a version manager, nvm was and still is a popular option, however, I now recommend and have been using fnm, a simpler and faster alternative to manage my nodejs versions.

The purpose of a version manager is to help you navigate or install any tools for development easily. Version Manager can be one tool for each dependency (e.g. NVM, g) or One tool for all dependencies (e.g. asdf, mise).

I usually develop on Windows so I installed NVM for Windows from here, but if you’re on other OS I’m sure you can find a version that supports it, probably this is the answer.

This was a very quick introduction to how I setup NodeJS on my environment using nvm. If you have any questions please refer to the official documentation or contact me via my Social Links.
