The Testimonials section cracked me up.

rhencke• 9 years ago

It looks like your testimonial has been added to the project, ha.

scardine• 9 years ago

Makes all these valid in Python:

    printf("printf %d\n", 10);

    fmt.Println("hello")

    cout << "Hello, C++!" << endl;

    Print["Hello from Mathematica!"]

    console.log("yes");

    System.out.printf("java stuff\n");

    Ada.Text_IO.Put_Line("Ada is cool")

Really funny, including the testimonials:

Anyprint has many glowing reviews from its many satisfied users: * "omg pls" * "what is wrong with you" * "That's stupid and not useful." * "Please add my testimonial: "very accurate testimonials"." * "kragniz, please stop writing questionable python metamodules :v"

cout << "Hello, C++!" << endl;

For the love of god, please stop using endl. It performs a flush when "\n" is both valid and all that you ever want.

Also what happened to the std:: prefix?

ben0x539• 9 years ago

Are you saying you never want to flush?

If flushing after every line is good enough for printf then it's gonna be good enough for me~

Please add support for:

    `0:"Hello from K.\n"

Why stop at print statements? After all if you find yourself successfully using the print statement from some other language, you might accidentally also use its if, for loop, file handling and class declaration constructs among many others. Who's looking out for those people? This is just the beginning!

stephengillie2• 9 years ago

Coming from Powershell, nobody told me JavaScript copies arrays by reference instead of by value. Why would anyone want to pass a reference?

cuchoi• 9 years ago

In Object Oriented Programming it can be useful if you want to pass the reference as the argument instead of the value.

amelius• 9 years ago

Now implement printing to a string (sprintf, etc.)

rhizome31• 9 years ago

How about Ruby, Perl or the Python 2 print statements?

systems• 9 years ago

All your testimonials are belong to us.

Can I have a D style:

  "Your text here".writeln;

emidln3• 9 years ago

You can in PyPy, where we can enable monkeypatching str

sdsk8• 9 years ago

You can monkeypatch str type with:

Ironically, what I miss most from Python is Python2's print, which for a language proud of getting rid of parenthesis, that is very contradictory....

fdej• 9 years ago

Same here. I will probably keep using Python 2 for as long as it works... simply because I don't have to type those parentheses.

sooheon• 9 years ago

As someone most at home in lisps--there's just no accounting for taste ;)

mixmastamyk• 9 years ago

Here's a nickel kid, buy yourself a decent editor. ;) Mine has snippets:

    pr<TAB>  --->  print('%cursor%', %cursor%)

dom96• 9 years ago

Perhaps you'd enjoy Nim which supports both.

    echo "hello world"
    echo("hello world")

and as a bonus, also the following:

    "hello world".echo

FRex• 9 years ago

Lua does too, for literal tables and strings being sole argument you can omit parentheses. But to call method on a literal you need to add them.

print("OK")
print "OK"
("OK %d"):format(1)

I've seen some funky (ab)use of these, people using literal strings and tables and functions named class and similar to do:

class "Something" {
-- ...
}

scrollaway2• 9 years ago

I'm a primarily Python dev, have been for a long time. Lately I've been working in Javascript/typescript and there is no worse antifeature than having 3 different ways of doing the same thing.

You try to figure out how to do something, you see 3 different solutions and you ask yourself, what's the difference? What's more correct? Will I need one over the other? Are they compatible? Is one way better supported than the other?

The amount of time I've spent looking up differences between two APIs or two paradigms in Typescript is seriously ridiculous. And it feels really bad to not recognize something you've done before because it's written differently.

Common culprits: require() and imports, the countless ways of creating classes, the crazy amount of different ways to implement similar or identical workflows in webpack and pretty much the entire JS ecosystem in general.

epalmer• 9 years ago

"hello world".echo

Okay I have to admit I love this one.

thehardsphere• 9 years ago

When I saw the title I thought to myself "this is going to be some elaborate troll about Python2 vs 3's print, isn't it?"

print chevron in python2 is super awesome

    print 'hello'
    f = open(file, 'w')
    print>>f, 'world'

It just feels more "powerful" than Py3k's

    print(somestring, file=someopenfile)

nhumrich• 9 years ago

More powerful

But less obvious and readable, which is anti pythonic. If you want "power" over readability, there is ruby/perl.

masklinn4• 9 years ago

print chevron in python2 is super awesome

Print chevron is super awful, it's unreadable, hard to remember and difficult to search for.

The print function was a welcome improvement: it's not a statement (so can be used in a lambda, no need to fall back to sys.stdout.write), it doesn't use weird-ass syntax to redirect or suppress the final newline and it's more extensible (e.g. "end" or "flush" kwargs would have been… challenging to add to the keyword version)

RodericDay• 9 years ago

If you want power you can

    fprint = lambda string: print(string, file=somefile)

and use fprint all over the place

that little chevron trick is bad imo

majewsky• 9 years ago

You'd like Perl:

  open my $file, '>', 'hello';
  print{$file} "Hello";

for a language proud of getting rid of parenthesis

Er… what?

Python doesn't have braces, it has plenty of parenthesis. In fact, Python 3 added more since it upgraded several keywords to functions (not just print but also exec, and some forms of re-raising)

Veedrac2• 9 years ago

Little known fact: The addition of `exec`-with-parenthesis actually long predates Python 3. Python 3 just removed the old, braceless version.

That this is so little known is why we have a complicated future.exec_, which is entirely needless! (https://stackoverflow.com/a/26098101/1763356)

flavio812• 9 years ago

Let's hope they also add

    (format t "hello ~a!" name)

for completeness...

emidln3• 9 years ago

They closed my issue for a clojure style

    (prn "hello world")

I was actually just looking into adding a hook for an automatic AST transformer so I could possibly call into Hylang.

sbmassey• 9 years ago

To say nothing of vitally important format expressions like

  (format t "~{~a~^, ~}" list)

stevelosh• 9 years ago

And of course the stuff necessary for word-wrap-in-`format`:

    (format t "~{~<~%~1,40:;~A~> ~}"
      '("these" "words" "will" "be" "wrapped" "to" "40" "characters"))

and the other `format` insanity in: http://cybertiggyr.com/fmt/fmt.pdf

umanwizard2• 9 years ago

Please add support for

    NSLog(@"Hello, %s and %s!", @"macOS", @"iOS");

jibberia• 9 years ago

Warning: Format specifies type 'char ' but the argument has type 'NSString '

umanwizard2• 9 years ago

Whoops! Should have been `%@`

cbanek• 9 years ago

Now we just need a nice restrictive license to grab all the patents.

rosstex• 9 years ago

I already sent this to my co-founder

nneonneo• 9 years ago

Worth noting: the language's syntax must still be minimally compatible with Python -- this isn't some sort of magic parser hack, it's just adding functions and types with special behaviour (like having "cout" be an object that overrides __lshift__). Now, given that many Lisp and Lisp-likes support ridiculous parser hacks (Scheme/Racket come to mind), I bet you really could pull off "Anyprint" in one of those languages...

derpydev• 9 years ago

This project is so wonderful it took down Github

krallja• 9 years ago

Ironically, it doesn't (and can't) support Python 2 print statements.

sandwell• 9 years ago

And by extension, QBasic's PRINT statement. 0/10.

laurentlb• 9 years ago

Lovely! The idea is very similar to NoFail ( https://github.com/laurentlb/NoFail), a language I've described, but not yet implemented.

RhysU• 9 years ago

Is Fortan's

  WRITE(*, *)

doable? How to handle the * isn't jumping out at me.

bjackman• 9 years ago

In all seriousness, it never occurred to me before that because of access to "globals", an import statement can introduce (or alter the value of!) unexpected names.
