Code golf for the lazy

Question

Your goal in this code golf is to take two strings, language and code (if the golfed code you wrote for this is multiline, then this variable would be multiline.), and one integer, bytes. They represent the variables for a programming language, number of bytes it takes, and the code itself.

After that, you are going to format it like a code golfer does it.

The output variable is a multiline string called answer.

You can use multiline strings on:

• C++
• Python
• Perl
• JavaScript

If you search Stack Overflow, you should be able to find more programming languages that support it.

Here is a template of the output markdown. The code variable is in a code block, and there is a second-level header.

## {language}, {bytes} bytes

     {code}

Here is what the output would look like when pasted into a Markdown parser.

{language}, {bytes} bytes

    {code}

Variables are assumed to be filled out already as the language you coded your code golf entry in, the number of bytes it takes, and the actual code for it.

Here is another example of the output as code, this time with variables filled out:

## JavaScript, 1337 bytes

document.getElementById("foo").innerHTML = bar;

Here is the version as a blockquote:

JavaScript, 1337 bytes

    document.getElementById("foo").innerHTML = bar;

Bytes can be taken off from your code if you use a way to set the text of a <p> element in HTML by the id result, like the following JavaScript code:

document.getElementById("result").innerHTML = answer;

Make sure to also include the <p id="result"></p> in the HTML section of JSFiddle for this to work.

Scoring

Like all code-golf questions, the code that uses the least amount of bytes is the best.

Answer 1

Java, 70 bytes

String A(String[]b){return"## "+b[0]+", "+b[1]+" bytes\n\n    "+b[2];}

Assumes b[0] is the language name, b[1] is the byte count, and b[2] is the code.

Making it compilable costs 9 bytes, resulting in a 79-byte non-standalone program:

class a{String A(String[]b){return"## "+b[0]+", "+b[1]+" bytes\n\n    "+b[2];}}

The equivalent monolithic program is 103 bytes long:

interface a{static void main(String[]A){System.out.print("## "+A[0]+", "+A[1]+" bytes\n\n    "+A[2]);}}

The monolithic one works with command line arguments, assuming these just like the non-standalone program:

• First argument is the language name
• Second argument is the byte count
• Third argument is the code

Java (lambda expression), 56 48 bytes

(b)->"## "+b[0]+", "+b[1]+" bytes\n\n    "+b[2];

This is a java.util.function.Function<String[], String>.

---

None of these programs/functions handle multiline strings. To do so, simply replace b[2] and A[2] with b[2].replace("\n","\n ") and A[2].replace("\n","\n ") - doing so adds 23 bytes.

Answer 2

V, 24 bytes

Note that there is a trailing space at the end.

This program makes the assumption that {code} will not be on multiple lines.

Op has clarified, "code" may be a multiline string. This 24 byte version works:

2é#á $á,JA bytes
vGî4é 

Since this contains an unprintable character, here is the readable version:

2é#á $á,JA bytes
<esc>vGî4é<space>

Where <esc> is the literal escape character, e.g. 0x1B.

Answer 3

Python 3.5, 40 33 bytes:

(-7 bytes thanks to some clarification from Mego)

lambda*f:'## %s, %s bytes\n\n\t%s'%f

An anonymous lambda function that takes inputs as positional arguments in the format <function name>(String, Number, String) and outputs a multiline string.

Answer 4

JavaScript (ES6), 56 bytes

(l,b,c)=>`## ${l}, ${b} bytes

`+c.replace(/^/gm,`    `)

Also, for laughs, here is an answer that formats itself for me:

JavaScript (ES6), 68 bytes

f=_=>`## JavaScript (ES6), ${`${f}`.length+3} bytes\n\n    f=${f};`;

Print the result of f().

Answer 5

C#, 40 38 bytes

(a,b,c)=>$"## {a}, {b} bytes\n\n\t"+c;

C# lambda where inputs and output are strings.

---

C#, 59 bytes

(a,b,c)=>$"## {a}, {b} bytes\n\n\t"+c.Replace("\n","\n\t");

With handling of a multiline answer.

Answer 6

Mathematica, 40 bytes

Print["## ",#,", ",#2,"bytes

    ",#3]&

Anonymous function. Takes the language, byte count, and program as input and prints the body to STDOUT.

Answer 8

Jolf, 24 22 bytes

"## ¦i, ¦j Ξ/u3

    ¦

Not much to explain here. ¦ means interpolated input.

Try it here! Output for the input in the link is:

## Jolf, 24 bytes

    some filler code I think

Input is as:

name

number

"code"

35tOj', 'j' bytes'10t4Z"j&h

Try it online!

The code block must be on a single line.

Explanation

35t           % Push 35 (ASCII for '#') twice
0             % Push 0. When converted to char, it will be displayed as a space
j             % Input string (language name)
', '          % Push this string
j             % Input string (byte count)
' bytes'      % Push this string
10t           % Push 10 (ASCII for linefeed) twice
4Z"           % Push string containing four spaces
j             % Input string (code)
&h            % Concatenate everything into a string. Implicitly display

Pyke, 25 bytes

"##"Q", "z" bytes"skd4*z+

Or

Pyke, 0 bytes

Try it here! - click the copy answer button ;)

EDIT - It's just a feature of the website, it's cheating (or at least I would consider it so) because it never parses an AST and the web program probably isn't considered part of the language due to it not interacting with the language much (even though it is running the Pyke interpreter)

Answer 15

(lambda(l c)(format"## %s, %s bytes\n\n%s"l(string-bytes c)(replace-regexp-in-string"^""    "c)))

Also, since it can sometimes be tough to escape quotes and what not, a usage example that copies the string to the clipboard. (Mark region and use M-:)
