Generate a Markdown Template for your Post

Question

Your task is simple: Write a program (or function) that takes no input and outputs something like this:

## *name*, *length* bytes
    *code*

Where *name* is the name of the language you are using, *length* is the number of bytes in your code, and *code* is your program's source code. If *code* contains multiple lines, it have four spaces before each line.

Here's a 124-byte example implementation in Python 3:

s = "## Python 3, 124 bytes{2}    s = {1}{0}{1}{2}print(s.format(s,chr(34),chr(10)))"
print(s.format(s,chr(34),chr(10)))

The output is:

## Python 3, 124 bytes
    s = "## Python 3, 124 bytes{2}    s = {1}{0}{1}{2}print(s.format(s,chr(34),chr(10)))"
    print(s.format(s,chr(34),chr(10)))

Which in Markdown is:

Python 3, 124 bytes

s = "## Python 3, 124 bytes{2}    s = {1}{0}{1}{2}print(s.format(s,chr(34),chr(10)))"
print(s.format(s,chr(34),chr(10)))

This is code-golf, so the shortest answer (in bytes) wins.

Answer 1

RProgN 2, 28 Bytes

«"  %s"F"#RProgN 2, 28 Bytes"

Answer 2

Underload, 48 bytes

(#Underload, 48 bytes
)(~:S(    ):S*aSaS(:^)S):^

Answer 3

Python 2, 58 bytes

_='## Python 2, 58 bytes\n    _=%r;print _%%_';print _%_

Answer 4

reticular, 58 bytes

"'34'c: 4*91+c:s:e:t:y:b: 85: :,:r:a:l:u:c:i:t:e:r: :#dqO;

Try it online!

Explanation: :c pushes the single-char string c. This builds the string "## reticular, 58 bytes", backwards character by character, reverses the stack, and Outputs everything, including the string captured by the initial quote.

Answer 5

CJam, 33 bytes

{"## CJam, 33 bytes"N@S4*\"_~"}_~

Works a lot like the Underload answer.

Stack trace (N represents \n)

{"## CJam, 33 bytes"N@S4*\"_~"}
{"## CJam, 33 bytes"N@S4*\"_~"} {"## CJam, 33 bytes"N@S4*\"_~"}
{"## CJam, 33 bytes"N@S4*\"_~"} "## CJam, 33 bytes"
{"## CJam, 33 bytes"N@S4*\"_~"} "## CJam, 33 bytes" N
"## CJam, 33 bytes" N {"## CJam, 33 bytes"N@S4*\"_~"}
"## CJam, 33 bytes" N {"## CJam, 33 bytes"N@S4*\"_~"} " "
"## CJam, 33 bytes" N {"## CJam, 33 bytes"N@S4*\"_~"} " " 4
"## CJam, 33 bytes" N {"## CJam, 33 bytes"N@S4*\"_~"} "    "
"## CJam, 33 bytes" N "    " {"## CJam, 33 bytes"N@S4*\"_~"}
"## CJam, 33 bytes" N "    " {"## CJam, 33 bytes"N@S4*\"_~"} "_~"

Answer 6

V, 25 bytes

ñi#V, 25 bytes<esc>o´ Ñ<esc>~"qpx

---

(This is not counted in the generated markdown, because I like providing explanations for my code :P)

Here is a hexdump, since the source code contains unprintable/non-ASCII characters:

00000000: f169 2356 2c20 3235 2062 7974 6573 1b6f  .i#V, 25 bytes.o
00000010: b420 d11b 7e22 7170 78                   . ..~"qpx

This answer is just a trivial modification of the standard extensible V quine.

Explanation:

ñ                                   " Run the following code one time, storing it in
                                    " register 'q'
 i                                  "   Enter insert mode
  #V, 25 bytes<esc>                 "   And insert the header
                   o                "   Open up a newline, and enter insert mode again
                    ´ Ñ             "   Enter four spaces, then a 'Ñ' character.
                                    "   (The reason we insert it uppercase, is because
                                    "   lowercase would end the loop now)
                       <esc>        "   Return to normal mode
                            ~       "   Toggle the case of the char under the cursor ('Ñ')
                             "qp    "   Paste the contents of register 'q' (this is the
                                    "   same as the entire program minus the initial 'ñ',
                                    "   followed by a 'ÿ' character because V is weird)
                                x   "   Delete the last character (the ÿ)
