FuncShell – A Haskell-based alternative to awk

[jaytaylor]

Do any of you know how they got such a beautiful looking shell [0]? I'd love to know if there's a clean way to achieve such a nice result.

EDIT

As an aside, FuncShell looks like a beautiful demonstration of how powerful Haskell can be. The source code is terse and clean.

The only oddity I noticed isthe rather large 68MB binary file committed into master in the repository [1]. Why do people do this? Especially on GitHub where there's support for cutting releases with a binary for each targeted platform...

If you're feeling adventurous you can also try Fish shell with it's collection of themes

Thanks for bringing it to notice. I did this and later realized I can opt for the github release option[0]. I will fix this and the installation url asap.

That's a pretty standard zsh with oh-my-zsh prompt: https://github.com/robbyrussell/oh-my-zsh

Scroll down a bit and you'll see it.

Though I personally prefer zsh with prezto, because oh-my-zsh feels too bloated and heavy:

Try zsh + oh-my-zsh https://github.com/robbyrussell/oh-my-zsh

I think the gif you linked is the vanilla oh-my-zsh theme.

It doesn't get much purer than pure - https://github.com/sindresorhus/pure

Also, the font is Adobe source code pro.

zsh + oh-my-zsh + agnoster zsh theme + powerline

Similar idea, but uses sqlite to make an awk like utility with sql syntax: https://github.com/dbohdan/sqawk

And just yesterday, people were asking [0] what Tcl is good for! This is a great example.

There's also q, which I've happily used for all sorts of data munging tasks:

https://harelba.github.io/q/

One example from that page:

   ps -ef | q -H "SELECT UID,COUNT(*) cnt FROM - GROUP BY UID ORDER BY cnt DESC LIMIT 3"

What happened to hell[1]? It was apparently destroyed by this commit[2].

Similar idea, but uses LUA as inline language: https://github.com/HeinrichHartmann/luawk

``` > printf abc | luawk -p '_:gsub("a","A")'

Abc ```

[srean]

An awk with a luajit backend would be quite interesting.

[omaranto]

Similar tools that use Python as the query language:

- The Pyed Piper: https://code.google.com/archive/p/pyp/

- Puffin: https://github.com/kespindler/puffin

Nice! How do I bring new function into scope though? This looks very similar to hawk, which has documentation on how to add your custom code [1].

Also, there are some nice CLI tools for JSON [2] or CSV [3] specific data.

[codygman]

I think hawk should steal the idea of aliasing "|]" personally ;)

[baldfat]

I always have mixed feelings on awk alternatives. I find awk to be one of the most underused tools in scripting. Awk has saved me numerous of times.

Now replacing latex with a modern syntax would be awesome!!!

[RodericDay]

I tried to explain to a historian with an open source textbook initiative the basics of latex. As soon as I opened the demo page that had looked nice enough, with him by my side, my heart sank. It's just so far away from being usable by non-technical users.

It's too bad, really.

I like how you made this version use pipes instead of being a shell. Do you have any plans to create a new JS version of Awkward using pipes?

[_iostreamer_]

I understand that this caters to a very specific audience which knows haskell. Hence I plan to support JS as the inline language. I don't want to create a new JS version because I want to learn more of Haskell :p

[ilurkedhere]

In typical usage, do you need the type hints much? I saw ":: Float" in there for the df example, for instance.

[_iostreamer_]

Not really, in the example of df, I was filtering on the basis of size, which is not int usually but a decimal value, hence I had to provide the type hint.

[rocqua]

I'm amazed by the powerline-command prompt. Shiny things seem to draw my attention a bit too much.

[c0achmcguirk]

Haha, me too! I want to read an article on getting my zsh prompt to look like that.
