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"

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

c0achmcguirk• 9 years ago

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

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

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

Abc ```

An awk with a luajit backend would be quite interesting.

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_4• 9 years ago

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• 9 years ago

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

_iostreamer_4• 9 years ago

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.

baldfat3• 9 years ago

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!!!

RodericDay2• 9 years ago

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.

baldfat3• 9 years ago

A good theme and sharelatex.com can go a long way to get someone to use it. I usually only get Math Majors to invest in it.

I did almost all my Master Theology papers in it. Just difficult to use different languages. I usually have to use one or all of these Greek, Hebrew, Aramaic, Latin, Danish or German in my papers. Latex didn't make that easy. Actually nothing does.

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...

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.

suprfnk• 9 years ago

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:

jorvi2• 9 years ago

Prezto is abandoned. If you absolutely need a framework go for Zim, although I like the simplicity of Zplug and adding plugins or themes as I need them.

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.

Unfortunately, unless you rewrite history, it'll stay in there and bloat the download for anyone who wants to clone the repo.

I don't know if I want to recommend rewriting history or not. But for what it's worth, I'm currently on a cellular connection and couldn't download something this size if I wanted.

rdnetto• 9 years ago

You probably want to compress it as well - that can easily reduce the file size by an order of magnitude.

Also, the font is Adobe source code pro.

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

Similar tools that use Python as the query language:

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

gregwebs• 9 years ago

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.

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