Recreate the ASCII-table as an ASCII-table

Question

Frequently while I'm code-golfing, I'll want to know what the ASCII value of a certain character is. One of my favorite resources for quickly looking up all of the printable ASCII characters is ASCIItable.com. This has a really nice image that not only shows the printable ASCII characters and their values, but also the unprintable and extended characters, and the values in hexadecimal, octal, and HTML:

Today's challenge is to recreate that ASCII table as an ASCII table instead of an image. To keep things simpler, we will not use control-characters (characters below 32) and we'll only show the decimal value and the character. In other words, your challenge is to write either a full-program or a function that prints or returns the following text:

Dec  Chr   | Dec  Chr   | Dec  Chr
----------------------------------
32   Space | 64   @     | 96   `
33   !     | 65   A     | 97   a

62   >     | 94   ^     | 126  ~
63   ?     | 95   _     | 127  DEL

Trailing spaces on each line, and a trailing newline are permitted. Since this is a kolmogorov-complexity challenge, your submission may not take any input, or access any external resources (such as a file or the web), and your goal is to compress the code to output this text as much as possible.

Standard loopholes apply, and the shortest answer in bytes wins. Happy golfing!

Answer 1

Python 2, 185 183 175 159 bytes

Saved 8 bytes thanks to FlipTack!

Still quite new to golfing in Python.

for a in["Dec  Chr   | "*3,"-"*39]+["".join(["%-5d%-6s| "%(l,('Space',chr(l),'DEL')[(l>32)+(l>126)]) for l in(i,32+i,64+i)])for i in range(32,64)]:print a[:-5]

Uses a nested list comprehension to generate the table body.

Ungolfed:

lines =   \
  ["Dec  Chr   | "*3, "-"*39] +                    # first two lines
    ["".join(                                        # join 3 parts of each line
      ["%-5d%-6s| " % (l, ('Space',chr(l),'DEL')[(l>32)+(l>126)]) 
        for l in (i,32+i,64+i)]                      # generate 3 parts of a line
      )
      for i in range(32,64)]

for line in lines: print line[:-5]

Just barely squeaking in under a hundred. I'm gonna see if I can beat Pyth, but I won't make any promises.

Here is a hexdump:

00000050: 2043 6872 b320 7c20 1bce 3335 7c44        Chr. | ..35|D

And here's how it works:

i32 | 64 | 96<esc>      " Insert some starting text
31ñ          ñ          " 31 times:
   Ù                    "   Duplicate this line
    <C-a>               "   Increment the first number on this line
         l.             "   Increment the next number
           l.           "   Increment the next number

Here is where it get's interesting. First, let me explain a vim-trick. While in insert mode, certain characters are inserted (all printable ASCII-characters, most unmapped characters above 0x7f, and a few others), but other characters have a side-effect. For example, 0x1b (<esc>) will escape to normal mode. 0x01 (<C-a>) will re-insert the last inserted text, etc. Sometimes, we want to insert these characters literally. So to insert a literal escape character, you must type <C-v><esc>. This works for all characters that have a side effect. So essentially, <C-v> is the equivalent of a backslash in languages with string literals that allow you to escape certain characters in a string.

The other useful trick with <C-v> in insert mode, is that it can be used to insert characters by code-point, in either Decimal, Hexadecimal, Octal, or Hexadecimal Unicode. Since we already have the numbers that correspond to certain ASCII values, we just need to put a <C-v> before those characters, and run the corresponding text as vim-keystrokes. This can be achieved with a regex command, and a "Do 'x' on every line" command. So we:

Í                       " Substitute globally:
 ä«                     "   One or more digits
   /                    " With:
    &                   "   The matched number + some spaces
        <C-v><C-v>&     "   A ctrl-v character, then the matched number again
                        "   Since ctrl-v is like a backslash, we need two to enter a literal ctrl-v character
Î                       " On every line:
 éi                     "   Insert an 'i'
   D                    "   Delete this line
    @"                  "   Run it as vim keystrokes

At this point, the buffer looks like this

32         | 64   @     | 96   `    
33   !     | 65   A     | 97   a

63   ?     | 95   _     | 127       

Now we just need some general clean up, which accounts for most of the bytes in this answer

bsDEL<esc>              " Change the literal 0x7f character to "DEL"
          F <C-v>27kd   " Remove a space from the lines that have too many

Ä                       " Duplicate this line

   Ä                    " Duplicate this line
    3R                  " And replace it with three copies of the following string:

Explanation (uncomplete and outdated)

The strategy here is that I'm using the line numbers to generate the ASCII code points.

Note: ^[ is 0x1b, ^V is C-v

First we generate all the characters.

iSpace             " insert Space
^[¬!~              " insert every character between ! and ~

The current buffer looks like

Space
!"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~

Now we insert a newline between these characters

     Ó./&ò         " insert a newline before every character (:s/./&\r/g)

Sub 100 club. I'm no longer convinced that :se ve=all is the best way of doing this. It's an extra... 11 bytes just for writing the |'s! But that's what I have.

I'm posting this almost in competition with @KritixiLuthos answer using :se ve=all to avoid some A <esc>'s. I'm not convinced that either method is better yet, so hopefully this can inspire some golfing on both parties and see which method takes the cake.

Normally looks like this:

    printf("Dec Chr | Dec Chr | Dec Chr");
    printf("\n--------------------------"); 
    for(;i<63;i++)

Java, 434 422 321 bytes

class A{public static void main(String[]a){
    int k=1,r,s=32;
    for(;k<4;k++)
        o("Dec   Chr  ",k);
    for(;k<37;k++)                                                                              
        o("-",k==36?3:4);
    for(k=r=s;!(k==64&&r==-63);r=k>95?-63:s,k+=r)
        o(k+"   "+((k>99)?"":" ")+(k==s?"Space":k==127?"DEL  ":((char)k+"    ")),k/s);
    }
    static void o(String s,int j){
        System.out.print(s+(j==4?"":j==3?"\n":"|"));
    }
}

Java is probably not the best language for this as there is the overhead of classes and main method...

You can eliminate main method using a static declaration, reducing the byte count down further:

class A{
    static{...}

but this results in an error (after otherwise successfully running):

Exception in thread "main" java.lang.NoSuchMethodException: A.main([Ljava.lang.String;)
    at java.lang.Class.getMethod(Class.java:1786)
    ...

The byte count does int include newlines or indentation.

The first two lines are just creating literal strings and leaving them on the pipeline. The first uses the comma operator , to create an array, and then -joins that array together to create the headers. The second is just a straight string multiplication.

The third line loops over 32..63 and each iteration sends three values $_, ($_+32), and ($_+64) into an inner loop. The inner loop does a PadRight on the value (adds the appropriate spaces to pad to 5 characters). That is then string concatenated + with the result of a nested pseudo-ternary ( )[ ]. The pseudo-ternary selects either the char representation of that number, or else Space or DEL if it's the appropriate value. Again, we PadRight the appropriate characters.

Those three strings (for example, 32 Space, 64 @, 96 `) are encapsulated in parens and -joined with the column markers into a single string. Each of those 32 strings are then left on the pipeline. At the end of execution, an implicit Write-Output inserts a newline between elements on the pipeline, so we get that for free.

breakdown

                        # print header
<?=($p=str_pad)(D,31,"ec Chr   | D"),$p("\n",32,"-");
while($i<96)            # loop $i from 0 to 96
    printf("%s%-4d%-6s",    # print formatted:
                            # string, 4 space decimal leftbound, 6 space string leftbound
        $i%3?"| ":"\n",                 # linebreak for 1st column, pipe+space else
        $o=$i%3*32+32+$i/3,             # ($i mapped to) ASCII value
        $i++?$i<96?chr($o):DEL:Space    # character
    );

Using %-N is worth the byte that rightbound numbers and character would save.
