marcel VS awk-vm

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))

Awk is awesome! Glad that they are looking to modernize the book. It wasn't really necessary, all the code examples in the original edition of the book still run just fine, although some are somewhat dated, like printing ASCII bar graphs. They also had examples of writing VMs, parsers and interpreters in the book, which run on modern implementations.[0]
