Do you recognize the PPCG logo? it looks like this, when you do an ascii art of it.

+---+
|PCG|
+---+
   v

Now, In this Code Golf, You will make a code, that makes logos for other sites, similar to the PPCG logo.

What You should do

The "Shortened" string will be the string, with all upper case letters and numbers in the input string.(Which would be PPCG when the input string is Programming Puzzles & Code Golf)

The "Box" (

+---+
|   |
+---+
   v

) should fit the Shortened string perfectly.(No bigger or smaller)

Also the v part should be exactly 1 down and 1 left to the down right +.

Then output the box which has the shortened string in it.

Example

Stack Overflow:

+--+
|SO|
+--+
  v

Area 51:

+---+
|A51|
+---+
   v

Rules

You may assume that the input contains at least one digit or upper case letter.

Standard rules apply.

Very closely related. Also related. – Martin Ender – 9 years ago

@MartinEnder Yes, Very closely related, but not duplicate. – None – 9 years ago

Also, This is Highly inspired by PPCG itself. – None – 9 years ago

Can you clarify what the text inside should be? For example, what if the name of the site was 99 bottles of beer. Would that be 99BOB? Does the box get bigger to compensate for that? Is there a maximum box size, or site name size? What kind of characters might appear in the site title? – James – 9 years ago

1@MatthewRoh The purpose of the links is so that the challenges show up in the sidebar, it's not a dupe vote. That said, I personally think removing the unwanted characters and also printing the ^ doesn't add much compared to the second challenge I linked, but I won't cast a dupe hammer on that but let the communitz decide whether they consider it a dupe or not. – Martin Ender – 9 years ago

Unlimited Box and Site name size. Also, if it was 99 bottles of beer, It would be 99. – None – 9 years ago

@MartinEnder The related ones you linked have a whitespace front and behind the string. mine don't. – None – 9 years ago

@MatthewRoh The actually seems like the most minor difference which isn't going to require any substantial changes to any of the existing solutions. The best case for this challenge is the acronymisation and the v. – Martin Ender – 9 years ago

Why does 99 bottles of beer become 99 and not 99BOB? Is everything after a number excluded? – Adnan – 9 years ago

Because It is numbers and uppercase, not numbers and first character. – None – 9 years ago

4If it was 99 Bottles Of Beer, it would be 99BOB. – None – 9 years ago

Oh okay, I missed that part :p. – Adnan – 9 years ago

@MatthewRoh That would be a useful test case to add. – James – 9 years ago

What about uppercase letters inside the string? i.e. would 99 bOttles Of Beer turn into 99OOB? – charredgrass – 9 years ago

Yes. Every uppercase letters. – None – 9 years ago

Vim, 42 strokes

:s/[^A-Z0-9]//g
YPVr-i+<DOWN><LEFT>|<ESC><C-V>ky$pYjppVr $xrv

Replace <DOWN> with , <LEFT> with , <ESC> with esc and <C-V> with CTRL+V.

Here's an animation of this script running (old version which uses a V instead of a v):

Animation

Explanation of the script:

:s/[^A-Z0-9]//g                               # Remove all the characters that are not uppercase or numbers using a Regex.
YPVr-                                         # Duplicate the current, and replace all the characters of the upper one with dashes.
     i+<DOWN><LEFT>|<ESC>                     # Insert a + on the upper line, and a | on the second line.
                         <C-V>ky$p            # Copy the + and | to the end of both lines.
                                  Yjpp        # Copy the upper line to the bottom two times.
                                      Vr $    # Replace the bottom most line with spaces and put the cursor on the last character.
                                          xrv # Remove the last character and replace the second last character with a v.

V 34 bytes

Ó[^A-Z0-9]
ys$|ÄVr-r+$.YLppVr x$rv

Note that this worked in an older version, but doesn't work in the current version on try it online. I changed Ä to YP which is functionally equivalent.

Try it online!

Explanation:

Ó[^A-Z0-9]

Remove everything except for digits and uppercase characters.

ys$|              "Surround this line with '|' characters.
    Ä             "Duplicate this line
     Vr-          "Replace this whole duplicated line with '-' characters
        r+        "replace the first character with '+'
          $       "Move to the end of the line, and
           .      "Repeat our last command. This is the same as 'r+'
            Y     "Yank the current line
              pp  "and paste it twice
             L    "At the end of our text

Now, the buffer looks like this:

+---+
|A51|
+---+
+---+

And our cursor is at the first column of the last line.

Vr                 "Change the whole last line to spaces
   x               "Delete a character
    $rv            "And change the last character to a 'v'

Retina, 43 bytes

[^A-Z\d]

.+
+$.&$*-+¶|$&|¶+$.&$*-+¶$.&$* V

Try it online!

This is the perfect challenge to demonstrate Retina, Martin Ender's golfing language.

This solution is divided into two steps (what we call stages), both stages being a replacement stage.

The first stage:

[^A-Z\d]

This matches the substrings which match [^A-Z\d], which is the characters that are not uppercase and not digits, and then substitute them by nothing, meaning deleting them.

The second stage:

.+
+$.&$*-+¶|$&|¶+$.&$*-+¶$.&$* V

The .+ matches the whole result, and then substitutes it with the second line.

In the second line:

  • $& refers to the whole match
  • $.& refers to the length of the whole match
  • $* means take the previous integer, repeat the next character that many times. Here $.&$*- means to repeat - however long the match is.
  • refers to a new-line.

I think you can remove some whitespace. It is automatically added after you paste the golfed code. – Erik the Outgolfer – 9 years ago

I cannot run the code with whitespace removed because the VBA editor adds it automatically so I can't verify that it will run with it missing. – tjb1 – 9 years ago

To justify removing whitespace, remove it in a text editor, then paste back into VBA. If VBA handles it correctly, you're good with the shortened version. – Joffan – 9 years ago

I've put it in notepad, removed spaces, pasted back into the VBA editor and spaces are back. The editor adds them, if you delete them in the editor and click the mouse anywhere, it adds them. I cannot test the program without them. – tjb1 – 9 years ago

Yep. But if the code you start with doesn't have spaces and they are automatically inserted by the VBA editor and then it works, you have tested your space-reduced code. – Joffan – 9 years ago

Haskell, 107 Bytes

This answer is heavily based on the answer by Zylviij and the comments by nimi. I would have added more comments to that answer, but alas, I don't have enough rep.

o n=t++'|':f++"|\n"++t++(f>>" ")++"v"where f=[c|c<-n,any(==c)$['0'..'9']++['A'..'Z']];t='+':(f>>"-")++"+\n"

Additional tricks used:

  • Replaced intersect by its implementation so the import can be dropped. (Side note: the implementation is nearly verbatim the library one, I couldn't find a shorter version.)
  • Moved the helper functions into the where clause so functions can use the n parameter internally.
  • After that, (#) was short enough to be inlined.
  • Put everything on one line to limit extra whitespace.

I originally tried to make this only using regexes, but it was much larger than I'd hoped, so I've used some string repetition instead.

Can you use ascii in Python? If yes you can use 47<x<58|64<x<91 :) – aloisdg moving to codidact.com – 9 years ago

@aloisdg Unlike C/C++, Python doesn't use an integral char type - all characters in Python strings are themselves strings, and cannot be directly compared with integers. It would need to be 47<ord(x)<58or 64<ord(x)<91. – Mego – 9 years ago

[x for x in n if x.isupper()^x.isdigit()] is one byte shorter than filter(lambda x:x.isupper()^x.isdigit(),n) – Leaky Nun – 9 years ago

@LeakyNun: filter will return a string, but the list comprehension will return a list, which won't be usable in the return value expression. – Nikita Borisov – 9 years ago

Why XOR? Can't you use OR instead? XOR is more complex, and thus slower AFAIK. x.isupper()^x.isdigit() -> x.isupper()|x.isdigit() – Erik the Outgolfer – 9 years ago

C, 171 163

Function f() modifies its input and prints out the result.

l;f(char*n){char*p=n,*s=n,c[99];for(;*n;++n)isupper(*n)+isdigit(*n)?*p++=*n:0;*p=0;memset(c,45,l=strlen(s));c[l]=0;printf("+%s+\n|%s|\n+%s+\n%*.cv\n",c,s,c,l,32);}

Test Program

Requires one parameter, the string to use in the favicon:

#include <stdlib.h>
#include <stdio.h>
#include <string.h>

int main(int argc, const char **argv)
{
    char *input=malloc(strlen(argv[1])+1);
    strcpy(input,argv[1]);
    f(input);
    free(input);
    return 0;
}

Why do you copy the argv element? – mame98 – 9 years ago

Because the function modifies its input. I'm not sure modifying the parameters in place is defined behavior. – owacoder – 9 years ago

never thought about this... according to this SO answer it should be fine: http://stackoverflow.com/a/963504/3700391

1You're using replicate, length and f exclusively in this combination, so you can merge them into one function: r=replicate.length.f and call it like r n '-'. You can save even more bytes by using an infix operator: (#)=replicate.length.f and n#'-' / n#' '. Additionally replicate.length is >> (with a singleton string instead of a char), so it's: (#)=(>>).f and n#"-" / n#" ", both without ( ) around it. – nimi – 9 years ago

1... also: no need for the ( ) around t n and f n. "|"++ is '|':. All in all: o n=t n++'|':f n++"|\n"++t n++n#" "++"V". – nimi – 9 years ago

R, 108 bytes

cat(x<-gsub("(.*)","+\\1+\n",gsub(".","-",y<-gsub("[^A-Z0-9]","",s))),"|",y,"|\n",x,gsub("."," ",y),"v",sep="")

Explanation

Going from the inside out (because who doesn't love assigning global variables from inside a regex), assuming s is our input string:

y<-gsub("[^A-Z0-9]","",s) keeps capitals and numbers, assigns the resulting value to y.

gsub(".","-",y<-...) replaces all characters with hyphens in the above.

x<-gsub("(.*)","+\\1+\n",gsub(...)) chucks a + on either end of the row of hyphens, and a newline, and we store that as x.

The rest is pretty straightforward, output in the appropriate order, and use the fact that the number of spaces before the v will be the same as the length of y.

  • PHP<5.4 with register_globals=1, call php-cgi -f <filename> x="<name>";echo""

  • for PHP>=5.4: replace $x with $_GET[x] (+6)

  • you may want to add -d error_reporting=0 to cli options

There are times when I love that PHP accepts newlines in constant strings.

  • str_repeat looked like a buddy here, but costs 3 bytes
  • <?=(<assignments>)?"<output>".v:0 costs 1 byte
  • <?=(<assignments>)," <output>",v; does neither cost nor save, but adds a leading blank line to the output
