Ваша задача - открыть окно браузера браузера по умолчанию на http://codegolf.stackexchange.com .

Ваш код должен открывать сам браузер и не может полагаться на открытый.

Это код-гольф , поэтому выигрывает самый короткий ответ в байтах.

You should add clarifications/restrictions to the question itself, since comments are not guaranteed to stick around forever.

Your spec is minimal, which led to alot of uncertainty over what is allowed to accomplish the task. Additionally, some probably consider it a trivial task. Still, you're in the positive ;)

GNU Emacs, 29 27 14 bytes

(eww"ppcg.ga")

EWW is a browser inside Emacs. The browse-web function is an alias for eww, and so that makes eww the default browser in Emacs:

Your job is to open a browser window of the default browser to http://codegolf.stackexchange.com.

Can you use www.ppcg.lol instead of http://ppcg.lol?

— AdmBorkBork

1

@TimmyD No, at first I tried with "www" but the protocol must be supplied (the behavior is different for example with "mailto://"). For user interaction, there is "browse-url-at-point" which prepends "http", but this is longer of course.

You shouldn't need the //, I don't think. (I don't use emacs, but it's generally accepted without the //)

Oration, 41 bytes

Not winning, but sure was fun. As of right now, I'm only 1 bytee behind python!

I need webbrowser
Now open "http:ppcg.ga"

Explanation:

I need compiles to import $1 with webbrowser being the module.

Now runs the following command from the module as module.command with the arguments of anything following.

So this compiles to:

#!/usr/bin/env python3
import webbrowser
webbrowser.open("http:ppcg.ga")

I do end up needing the http: part though, and it can't be shortened.

You can use start www.ppcg.lol instead to implicitly have Windows parse it as HTTP. Works in both CMD and PowerShell.

@Blender Because otherwise it tries to find a local program called pccg with the .lol file extension and run it.

open is an OSX utility, not a bash one; this would be more appropriately called "OSX command line".

@Skyler Is this incorrect then? ss64.com/bash/open.html

— Mwr247

1

the first line: "Open a file in its default application, using virtual terminal (VT)." If you try to run that on unix, it will tell you "Couldn't get a file descriptor referring to the console", because it's trying to open in a terminal, not in a browser.

MATLAB, 28 25 bytes

web www.ppcg.lol -browser

www is shorter than http:// and ensures that the address is processed as a URL
This is shorter using the implicit function call (which casts inputs as strings) rather than the explicit version web('www.ppcg.lol', '-browser').
If you are on a OS X, this can be simplified to web ppcg.lol -browser as MATLAB will automatically append an http:// (21 bytes)

Alternatives:

On windows this can be shortened to (19 bytes)
```
!start www.ppcg.lol
```
On OS X (21 bytes)
```
!open http://ppcg.lol
```
The following would work in a deployed MATLAB application (16 bytes)
```
web www.ppcg.lol
```
If the built-in browser could be used this could be reduced even further as http is implied (12 bytes)
```
web ppcg.lol
```

— Suever

OS X is redundant because the built-in open command does the same.

@CrazyPython That's precisely what ! does in MATLAB, it's the equivalent of system(command). I had it as more of a demonstration of other alternatives that could be executed from within MATLAB. Is that OK?

— Suever

Do you need the www.?

— Addison Crump

@CoolestVeto Sometimes you do sometimes you do not. When using the external browser you do, however the internal browser you do not. If you do not specify it, no browser window will open. If you can get it to work, I'm more than happy to change it!

— Suever

The former change leaves it exactly the same length. As for the http://, if you leave that out it tries to open a local file called "ppcg.lol", which doesn't exist.

@cat actually, I've never been called out on this before - I've always operated on the assumption that bytes is the default for codegolf (and is even explicitly specified in this question), so explicitly respecifying in answers is just redundant information. Do you know of a meta post about this?

— Digital Trauma

Well, first and foremost, my comment was messing around -- I only changed it for consistency with all the other answers, and it's really insignificant but it bothered me. I'm pretty sure there's no meta post on formatting specifically, and that this format came from the Leaderboard Stack Snippets, but I'm almost certain there's a meta post for Defaults for Scoring Code Golf that says it's bytes unless otherwise specified.

I used to have lots of fun creating tiny programs in VBScript, back in 2010.

I've remembered this language and used the code on: https://stackoverflow.com/a/13401872/2729937

It still works on Windows 7, at least.

set S=CreateObject("WScript.Shell")
S.run("www.ppcg.ga")

This is a bit different from the usual start www.ppcg.lol, in the sense that it executes the www.ppcg.ga directly, with an implicit start.

An alternative way would be "cmd.exe /C start www.ppcg.ga".
