Our task is to, for each letter of the (English) alphabet, write a program that prints the alphabet, in a language whose name starts with that letter.

Input: none

Output:

abcdefghijklmnopqrstuvwxyz

uppercase and trailing newline optional

Rules:

  • The scoring metric is the length of the programming language name, plus the length of the code. Hence, C will be assessed a "penalty" of 1, while GolfScript will be assessed a penalty of 10.
  • One language/implementation per answer. Multiple answers are encouraged.
  • If a programming language name's first letter is not an English letter, it should not be coerced into one. It will be treated as a separate letter (meaning less competition).
  • No answer will be accepted until every English letter has a solution.

P is for Powershell, 19 + 10 = 29

Because I'm bored at the moment, I hope you don't mind if I put up a quick PS that wouldn't have contended anyways...

97..122|%{[char]$_}

Simple char typecasting. You can shave off one byte by doing the alphabet in all caps.

65..90|%{[char]$_}

  • \$\begingroup\$ The output is wrong. This one outputs the alphabet with one character per line instead of all on one line. \$\endgroup\$ – Joey Oct 31 '19 at 20:26

X is for XJam, 6 + 4 = 10

'[,65>

What is XJam, you may ask? It's a language I started creating earlier this year and gave up before doing anything really interesting. It technically does fulfill its design criteria though, which is to be a version of CJam which adapts to the informal specification in the xkcd comic X. It accomplishes this by using a custom charset where Unicode characters representing variations on the letter X fill the top 32 slots in what's otherwise standard 7-bit ASCII. Those characters are then the only ones which can be used as variables. It also happens to be perfect for this challenge, beating the previous x answer by two. (Sorry Peter Cordes, that x86 answer was great!)

Credit where it's due, the code is taken from Lynn's answer on a different question here. It doesn't use variables so it ports over perfectly.

Eso2D, 15 bytes + 5 = 20

2v
,>#1~5
@#,5<

Eso2D is a language starting with E that has a relatively short name and an instruction set very good for string construction that I found on the esolang wiki. This could probably be improved further, but it's more than enough for a new best E.

Explanation:

2v        Increment the accumulator by 97 and move down to the second row
,>#1~5    Loop (from wrapping): print num to char, add 50, check if > 170, decrement by 49 otherwise.
@#,5<     Once it hits 171, decrement by 49 and print one last time before stopping.
