# A keyboard so real you can almost TASTE it

... Not that you would, would you? The task is simple, output the following text:

This is the keyboard of the future because in the future spaces are irrelevant, so are spacebars.

To make things a little bit easier on you:

1. 0123456789ABC...XYZ-=[]\;',./ - These chars are on keys of length 6 (including padding).
2. TAB / BS / ENTER - These keys are of length 10 (including padding).
3. CAPS - This key is of length 11 (including padding).
4. SHIFT - This key is of length 13 (including padding, on both sides).

Each individual key looks more or less like this:

____
||* ||
||__||
|/__\|

However, you should make note that two consecutive keys are not:

____  ____
||* ||||* ||
||__||||__||
|/__\||/__\|

But they are "conjoined":

____ ____
||* |||* ||
||__|||__||
|/__\|/__\|

This challenge shouldn't be too bad, best of luck to you; don't miss out on abusing the repetition! But don't underestimate the "special" keys either ;).

# Winning?

Shortest code wins because it's you know.

Try it online!

Watch it run! This is a slightly modified version that updates as it runs so you can sorta see how it works. This is an outdated version since I haven't gotten around to re-recording it yet, but the general approach is identical.

This is probably the longest V answer ever written. It certainly didn't help that V's interpreter is extremely slow. It took me around an hour to write the first revision, but I've been repeatedly coming back to it to shave a couple bytes off each time. Since the full keyboard is 1215 bytes, currently this answer is 91% shorter than the output, so I'm pretty happy with the results.

Since this contains some unprintable characters, and a lot of gross non-ASCII, here's a hexdump:

## How the heck does it work?

Alright, this explanation is gonna be a doozy. You ready? First off, we need enter the letters so we can build up the keys around them. This is

¬19ÉA0-=BS´
TAB³ qwertyuiop[]\
CAPS³ asdfghjkl;'ENTER
SHIFT´ <esc>ÄJizxcvbnm,./<esc>

Which inserts:

1234567890-=BS
TAB   qwertyuiop[]\
CAPS   asdfghjkl;'ENTER
SHIFT    zxcvbnm,./SHIFT

It enters it pretty straightforward, but there are a few tricks that we use to save characters. For example, ¬19 enters "123456789", ³ enters three spaces, and we duplicate the shift so that we don't need to enter it multiple times.

Note how the letters are lowercase here. This is so that we can easily distinguish between the uppercase keys like "ENTER" and the single letters. Writing them this way makes it easier to tell which characters to put a bar before, and only adds one byte to convert them to lowercase later. So we do a substitute command to convert these to uppercase, and add one space after each of them:

Í               " Globally replace
[^A-Z ]        " Anything but a uppercase alphabet character or a space
/       " with
Õ&     " The matched pattern made uppercase, followed by a space

Now, we take each key sequence (any run of non-whitespace), and put three bars before and after them:

Í           " Globally replace
Ó«         "   Any number of non-space characters
ü        "   or
$" an end of line / " with ||| " Three bars & " And the matched pattern At this point, the buffer looks like this: ||| |||1 |||2 |||3 |||4 |||5 |||6 |||7 |||8 |||9 |||0 |||- |||= |||BS ||| |||TAB |||Q |||W |||E |||R |||T |||Y |||U |||I |||O |||P |||[ |||] |||\ ||| |||CAPS |||A |||S |||D |||F |||G |||H |||J |||K |||L |||; |||' |||ENTER ||| |||SHIFT |||Z |||X |||C |||V |||B |||N |||M |||, |||. |||/ |||SHIFT ||| Having three bars on the first and last columns is actually very convenient and ends up saving many bytes in the long run. And here is where we run one giant loop. This will convert something like this: |||SHIFT |||Z |||X |||C |||V |||B |||N |||M |||, |||. |||/ |||SHIFT ||| into something like this: ___________ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ___________ ||SHIFT |||Z |||X |||C |||V |||B |||N |||M |||, |||. |||/ |||SHIFT || ||_________|||__|||__|||__|||__|||__|||__|||__|||__|||__|||__|||_________|| |/_________\|/__\|/__\|/__\|/__\|/__\|/__\|/__\|/__\|/__\|/__\|/_________\| Everything between two instances of ò will run until an error happens, which will happen when we try to go up into a line that does exist yet. Since we just ran a globally substitute command, our cursor is on the last line, and we'll transform these working our way up. ò " Recursively: Ù " Duplicate this line Ó " Substitute all on this line: [^|] " Anything but a bar / " With: _ " An underscore This is the |||_________|||__|||__|||__|||__|||__|||__|||__|||__|||__|||__|||_________||| line. Ù " Duplicate this line Ó " Subsitute all on this line: ×« " A run of *non-word characters* (that is, [^0-9A-Za-z_]) / " With: Ü|¯ " '\|/' This is the \|/_________\|/__\|/__\|/__\|/__\|/__\|/__\|/__\|/__\|/__\|/__\|/_________\|/ Line. kk " Move up two lines (to the original text with "SHIFT") P " Paste the last line we duplicated (the one with all the underscores) Ó " Substitute: " Since we don't give any regex here, it re-uses the last one " (a run of *non-word* characters) / " With: _ _ " '_ _' This is the: _ ___________ ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ ___________ _ Line. k " Move up a line (this will throw an error, breaking the loop when we're done) ò " Endwhile Now we have the full keyboard, but each line contains either an extra bar, an extra slash (forward or backward), or an extra underscore. Super easy fix Î " On every line: x " Delete a character$           "   Move to the end of the line
x          "   and delete another character

After all that madness, the buffer is implicitly printed.

I'm going to get destroyed by other langauges, but I thought I'd give this a shot. Nice amount of complexity, and atleast it's shorter than the keyboard!

• Screw other languages, you were the first in a rare language! Impressive, though I'm sure you definitely don't need to put pipes as delimiters on every letter. Notice how the "special" keys are only at the front and end of lines. I'm sure that hint could save you precious bytes somehow. – Magic Octopus Urn Dec 13 '16 at 0:03

I'm halfway embarrassed to be posting this answer, given how short the PHP and Python answers are, nevermind the C# answer, but I'm unable to get this method shorter. Other approaches may yield better results.

It's basically just a giant multi-line string, with variables ($a and the like) substituting for various substrings, and a couple -replaces at the end to finish it out. Script blocks$(...) are inserted where necessary to introduce new variables.

Try it online!

Python, 493 458 Bytes.

k=[['|']*75 for i in [0]*16]
v=' '
w='_'
y=0
def a(s,x,o):k[y+o][x:x+len(s)]=list(s)
def p(s,i,x):a(s+v*(i-len(s)),x+2,1);a(v+w*(i+2)+v,x,0);a(w*i,x+2,2);a(w*i,x+2,3);a('/',x+1,3);a('\\',x+i+2,3);return x+i+3
def q(s,x):return reduce(lambda a,b:p(b,2,a),list(s),x)
p('BS',6,q('1234567890-=',0))
y=4
q('QWERTYUIOP[]\\',p('TAB',6,0))
y=8
p('ENTER',6,q('ASDFGHJKL;\'',p('CAPS',7,0)))
y=12
p('SHIFT',9,q('ZXCVBNM,./',p('SHIFT',9,0)))
for l in k:print''.join(l)

Functionally equivalent but somewhat more readable:

k=[['|']*75 for i in range(16)]
def a(s,x,y):k[y][x:x+len(s)]=list(s)
def p(s,i,x,y):
a(s+' '*(i-len(s)),x+2,y+1)
a(' '+'_'*(i+2)+' ',x,y)
a('_'*i,x+2,y+2)
a('_'*i,x+2,y+3)
k[y+3][x+1]='/'
k[y+3][x+i+2]='\\'
return x+i+3
def q(s,x,y):return reduce(lambda a,b:p(b,2,a,y),list(s),x)
p('BS',6,q('1234567890-=',0,0),0)
q('QWERTYUIOP[]\\',p('TAB',6,0,4),4)
p('ENTER',6,q('ASDFGHJKL;\'',p('CAPS',7,0,8),8),8)
p('SHIFT',9,q('ZXCVBNM,./',p('SHIFT',9,0,12),12),12)
for l in k:print ''.join(l)

• You can put the lines in the p function on one line separated by semicolons. Also, I thought that you can't make the first line k=[['|']*75]*16, do you know why? – nedla2004 Dec 13 '16 at 1:30
• You can also define '_' and ' ' to a variable to save some bytes. – nedla2004 Dec 13 '16 at 1:34
• Thanks for the tips! I think k=[['|']*75]*16 creates sixteen references to the same array so a change in one line affects the others as well. – Cobi Dec 13 '16 at 1:35
• Okay, then you can at least change range(16) to [0]*16. – nedla2004 Dec 13 '16 at 1:49
• A small issue is that your code does not technically produce the right output, but you can fix that by changing for l in k:print ' '.join(l) to for l in k:print''.join(l). – nedla2004 Dec 13 '16 at 1:51

Yeah, I know, compression. But it works, no?

gunzip<f

Requires a file called "f" in the current directory with the following contents (put into base64 for PPCG-friendliness - you can decode this into the file "f" first.):

• Can be made trivially shorter by writing gunzip<f. – Konrad Rudolph Dec 13 '16 at 12:00
• @KonradRudolph Excellent point. Thanks. – Addison Crump Dec 13 '16 at 15:20
• You can save 2 bytes with zcat f, and 2 bytes by removing the two trailing null bytes (gzip complains but produces the desired output). – Gilles 'SO- stop being evil' Dec 14 '16 at 11:18
• @Gilles Doesn't really save me bytes - I'd have to rename the file "f.Z" (on OSX at least). Removing the trailing null bytes not only makes gzip complain - it makes it error out and not print anything. – Addison Crump Dec 14 '16 at 12:15
• @VoteToClose Oh right, zcat<f then. On Linux, zcat without the trailing zeroes makes gzip complain (“gzip: stdin: unexpected end of file”) but only after printing the desired output. – Gilles 'SO- stop being evil' Dec 14 '16 at 12:57

UPDATE 1: Replaced for by foreach, because latter produces shorter code

UPDATE 2: Replaced foreach by lmap, because latter produces shorter code

UPDATE 3: Shaved one char because I Replaced " " by \

UPDATE 4: In respect to first comment, I changed all the 1st line 2 byte Unicode place holder characters to 1 byte ASCII ones

UPDATE 5: multiple puts line made into only one

UPDATE 6: use directly split commands return values on the lmap call instead of using intermediate list variables

UPDATE 7: Quotes around ENTER were not needed

UPDATE 8: string map is long enough and repeated a number of times that it is worth to encapsulate it in a proc

UPDATE 9: split $x \n is long enough and repeated a number of times that it is worth to encapsulate it in a proc UPDATE 10: On "replacement" string can use & instead of \1, because in this case both coincide; another consequence of this is it allows to get rid of ()on the "matching" string. UPDATE 11: Use @ instead of \nas line separator for further use on split instructions. Although the "match" string lengthens from \S to [^@] it pays off , due to number of repetitions UPDATE 12: Replaced the first regsub "match" string {[^@|]} by$^@|] to shave one character off. Unfortunately, could not do the same to the second regsub, because the instruction is inside a pair of [] :( UPDATE 13: Shaved two Enter characters by concentrating the lmap body with its own heading. UPDATE 14: Used a call to the split based procedure N instead of a direct call to the string map based procedure N which allows to shorten by 3 characters UPDATE 15: There was an unneeded space character. Removed it to shave one char off. UPDATE 16: set h can be embedded to get rid of h, to shave one character off. UPDATE 17: set h statement can really be shaved off. UPDATE 18: puts argument changed from the ...\n...\n...\n... format to the "... ... ... ..." format. Thanks to people that helped me to shorten it, especially evilotto and aspect of the tcl IRC channel! • Nice answer, and Welcome to the site! I made a minor edit to your post so that the byte count would appear in the header, I hope you don't mind. Just so you know, I think this is actually 469 bytes since some of those characters are multiple bytes in UTF-8. I don't know very much about tcl, does it use a custom encoding where those are one byte? – James Dec 18 '16 at 18:17 • @DJMcMayhem I didn't know it was based byte count instead of character count but it is a non-problem because everything that is a one byte symbol still not used can be a placeholder and I still have many available. – sergiol Dec 18 '16 at 21:56 • @DJMcMayhem after my edit, the non-problem you reported has gone! – sergiol Dec 18 '16 at 22:12 • @DJMcMayhem Why the 401 on top had a yellow background for some time? – sergiol Dec 20 '16 at 14:57 ## tcl, 369 Initially based in tcl's sergiol version.

• Explain further, I did not understand you. @nneonneo – Whatever Dec 21 '16 at 16:52
• If you paste your code into a file, that file will be 672 bytes long. You appear to have counted your code with len("print 'x\x9c...'") which will unescape the \xs, resulting in an incorrect byte count. You could obtain a correct count by counting with len(r"print 'x\x9c...'") but the easiest solution, as always, is to see what your text editor or filesystem says. – nneonneo Dec 21 '16 at 17:05

## Extra: keyboard with a space bar & right aligned labels, 278 bytes

I've added a couple of bytes to the regular expression to handle the space bar (old regexp (.[a-z ]*), new one ~|(.[a-z ]*)). That's one small step for the regexp, one giant leap for the solution: you can now display space bar and key labels aligned to the right (see SHIFT, CTRL and BS on the right side of the keyboard).
