... and many also have succeeded. fish would not be as popular as it is otherwise, other alternative shells that break bash compatibility are being worked on and are gaining traction, elvish, nushell, murex... mixing shells is not as hard as some people claim. it's like switching programming languages. i do that all the time. but then, i avoid bash scripting as much as i can (or shell scripting in general). if you ac…

I might be in a minority, but I actually prefer fish as an interactive shell and bash (or plain /bin/sh) for scripting, if anything because that's what I'm used to :), and it's portable

Really like using fish as my interactive shell too.

I'm recently seeing more and more Ruby projects that are at least partly vibe-coded, and I'm kind of torn. On the one hand I appreciate that this allows people to create stuff that they maybe wouldn't have the time to do otherwise. On the other, the code itself makes it harder for people to contribute, especially those, like me, who don't use coding agents. A random example: https://github.com/amatsuda/rubish/blob/ma…

Honestly I don't know why would you choose ruby for vibecoding. This is a language that explicitly sacrifices important stuff like the strength of automatic checks possible and performance in lieu of developer ergonomics. Even if you support that particular choice, chosing the language when you won't be writing or reading most of the code is a pretty poor tradeoff.

There is a study that reported ruby as the best language for LLM over something like 15 languages

But why would it be a first april article? Are there any arguments to be made for this statement? Because the shell works, I just tested it. It may not be everyone's cup of tea but that's always the case for any given software. The primary reason I use bash over, say, zsh, despite thinking zsh is more advanced, is that I use bash mostly because it is very simple. I like simplicity. (Bash could be even simpler, I woul…

It is a clever title. It would be funny to have an April fool sounding hook but backed by a legit project.

many years ago i wrote a parser for a python like syntax for pike which is C-syntax based. i wrote it just for fun, but it actually worked. i called it nessie, like the loch ness monster because pike(fish)+python(snake)=nessie(sea snake). i did post it on april 1st. someone took it seriously anyways. wonder if i should repost it, and then make a new release once a year, always on april 1st...

Tangential: I would love to see more interpreted languages offer shells with native constructs for operating as daily drivers shells (not just REPLs). When I first started learning Ruby I used `rush`[0] as my main shell. Being immersed in the language, even if there were a few helpers for shell operations, really helped me reason better about Ruby and think in the language. `scsh`[1] was enlightening as well.

Not sure if this is related, but i'd love to see more scripting languages (mostly Python) offer facilities which let them take over from shell script for more scripts and one-liners. Think about what it would take to write this in Python right now: for wmv_file in $(find $1 -name '*.wmv'); do echo -n "${wmv_file} " ffmpeg -i $wmv_file ${wmv_file%.wmv}.mpg 2>&1 | grep kb/s: || echo "ERROR $?" done With a few handy var…

How about

  for wmv in Path(sys.argv[1]).rglob("\*.wmv"):
        print(wmv, end=" ")
        r = subprocess.run(
            ["ffmpeg", "-i", wmv, wmv.with_suffix(".mpg")],
            stdout=subprocess.PIPE, stderr=subprocess.STDOUT,
        )
        lines = [l for l in r.stdout.decode().splitlines() if "kb/s:" in l]
        print("\n".join(lines) if lines else f"ERROR {r.returncode}")
?

If you go outside stdlib you can use the sh library instead of subprocess.run.

Hmm. The name is a bit awkward since people can call it "rubbish". The idea is also not quite new in that many years ago people worked on an ruby-like shell with OOP support from the get go and they used a ncurses drop down box too. I forgot the name, but it must have been before 2010 already, as I vaguely remember it from talking on IRC back in those days. I think the main developer was from South Africa, but I don'…

> Rails is also ancient already. I think Rails both boosted Ruby and killed it. When I ask people about why they dislike Ruby it's usually due to something specific to Rails (plus some comments around syntax which are easily dismissed or accepted). I used to be a pretty heavy Ruby user and I still love the language, though I have only used Rails sparsely and not by choice. I had the opportunity to work on a Ruby proj…

just yesterday i was searching for CMS alternatives. i found dozens in php, but only a single one in ruby. i found that disappointing. python did no better. i found two. there is really no reason for php to be dominating this space.

can't find ruby skills? they are searching for the wrong thing. they should hire an experienced programmer who could learn ruby in a week and not expect someone who has been working exclusively with ruby for the past few years. those people already have jobs.
