As you probably know, there have been multiple lovely Jimmy challenges recently popping up. In these challenges, you were challenged with our beloved friend's acrobatics skills. Now we've got a different challenge for you. Today you will be identifying different types of Jimmys!

Explanation

There are three varieties of Jimmys: dwarf, acrobat, and bodybuilder.

This is dwarf Jimmy:               o

This is acrobat Jimmy:            /o\

This is bodybuilder Jimmy:       /-o-\

These Jimmys are all great friends and they like to stand on the same line as each other. Your task is, given a Jimmy scene like so:

  o  /o\       o   /-o-\/-o-\  o          /o\

Output the amount of dwarves, acrobats, and bodybuilders on the line, respectively.

The challenge

  • Take input in any reasonable form as a Jimmy scene, as shown in an example above.

    1. The input string should be one line and optionally contains the three varieties of Jimmys and optional whitespace.

    2. The string will not necessarily contain all of the Jimmy varieties or whitespace.

    3. The string will not contain any characters not in o/\ -.

    4. Any combination of Jimmy varieties is possible. This means that the same or different type of Jimmy can be next to each other. You must account for that.

    5. Leading and trailing whitespace is optional and by no means required - your program should account for a string with or without leading and/or trailing whitespace.

    6. The string should contain only valid Jimmys and whitespace. For instance, ---///--- is not allowed because it is not a valid Jimmy sequence.

  • Output three numbers: The count of dwarves, acrobats, and bodybuilders in the scene (in respective order).

    1. This may be an output to the console as space-separated integers, or it may be a return value from a function as some sort of container (i.e an array type).

    2. The output, in whatever format, must be ordered as mentioned in the top bullet above this rule.

  • Standard rules and loopholes apply.

Test cases

     /-o-\           /-o-\     o/o\  /-o-\       /-o-\                /-o-\
OUTPUT: 1 1 5


      o o               /o\    o o      o                    /o\             /o\
OUTPUT: 5 3 0


 /-o-\     /-o-\            /-o-\/-o-\   o /o\/o\    /-o-\o /-o-\       /o\/-o-\
OUTPUT: 2 3 7


  /-o-\  o                 /-o-\               o/o\
OUTPUT: 2 1 2

If you'd like more test cases, use this tool to generate more random test cases.

Scoring

This is , so lowest score in bytes wins.

You can view the leaderboard for this post by expanding the widget/snippet below. In order for your post to be included in the rankings, you need a header (# header text) with the following info:

  • The name of the language (end it with a comma , or dash -), followed by...

  • The byte count, as the last number to appear in your header.

For example, JavaScript (ES6), 72 bytes is valid, but Fortran, 143 bytes (8-bit) is invalid because the byte count is not the last number in the header (your answer will be recognized as 8 bytes - don't take advantage of this).

Jelly, (12?) 13 bytes

ċⱮ“-/o”H1¦ŻIṚ

A monadic Link accepting a list of characters which yields a list of integers, [ dwarves, acrobats, and body-builders] (save the Ṛ byte if we may specify our output)

Try it online!

How?

All Jimmys show a o; all non-dwarves show a /; all body-builders show two -. Count these up, halve the count of -, and perform subtraction to find the Jimmy counts:

ċⱮ“-/o”H1¦ŻIṚ - Link: list of characters
  “-/o”       - list of characters ['-', '/', 'o']
 Ɱ            - map across right with:
ċ             -   count occurrences   = [n('-'), n('/'), n('o')]
         ¦    - sparse application...
        1     - ...to indices: [1] -- i.e. n('-')
       H      - ...action: halve    = [n('-')/2, n('/'), n('o')]
          Ż   - prepend a zero =   [0, n('-')/2, n('/'), n('o')]
           I  - incremental differences
              -     = [n('-')/2, n('/')-n('-')/2, n('o')-n('/')]
            Ṛ - reverse
              -     = [n('o')-n('/'), n('/')-n('-')/2, n('-')/2]

  • \$\begingroup\$ @HyperNeutrino That's basically the one reason that you might now see "Python 3.8 (pre-release)" floating around the site. Another restriction is that, unless it's on its own and not the only expression in a statement (in which case you might prefer regular assignment instead), it must be parenthesized (+2 bytes). \$\endgroup\$ – Erik the Outgolfer Jul 15 '19 at 17:12

Try it online!

Explanation:

                            'o/-'=/] compare the input with each one of "o/-" characters
                                     / the result is a 3-row matrix /
                         1#.         add up each row to find the number of occurences
                                     of each character, the result is a vector of 3 items
                  1 1 2%~            divide the last item by 2 to find the number of 
                                     bodybuilder Jimmys
[:(              )                   use the result to construct the following vector:
               {:                    the last item
              ,                      appended to
         -/@}.                       the difference of the second and the third items
        ,                            appended to
   -/@}:                             the difference of the first and the second items

Retina, 39 35 bytes

Edit: -4 bytes thanks to @FryAmTheEggMan

^((o)|(/o.)|(/-o-.)| )*
$#2 $#3 $#4

Try it online!

Explanation:

A simple replace stage. It finds all matches of the regex ^((o)|(/o.)|(/-o-.)| )* (which should result in one match - the whole string) and replaces it by the number of captures of groups 2, 3, and 4. Here is the regex broken down:

^((o)|(/o.)|(/-o-.)| )*
^                               start at the beginning of the string
 (                       )*     have any amount of Jimmy / spaces
     |       |         |        select one of:
  (o)                           capturing group 2 - dwarf
      (/o.)                   capturing group 3 - acrobat
              (/-o-.)         capturing group 4 - bodybuilder

We have to start with ^ or the end of the input counts as a match too. In the substitution syntax of Retina, $n references the nth capturing group, and the modifier # counts how many matches it made.

Counts the number of times o appears without being followed by \ or - to find the dwarves and removes them from the string. Then counts the number of times /o appears to find the acrobats and removes them from the string. Then counts the number of o remaining to determine the body builders.

Explanation

  • Get Count of /, -, and o characters
  • Bodybuilder is number of - characters divided by 2
  • Acrobat is number of / characters minus the number of body builders
  • Dwarf is number of o characters minus the number of Acrobat and Bodybuilders

Code Explanation

\ c counts the number of occurrences of the given character in a string
\ stack usage is ( c-addr u1 w1 - u )
: c                 \ start a new word definition
  -rot 0 tuck       \ sets up parameters for a counted loop
  do                \ loop from 0 to string-length - 1 (inclusive)
    over i +        \ get the address of the current character in the string
    c@              \ get the ascii value of the current character              
    3 pick =        \ compare it to the character we're counting
    -               \ subtract result from the accumulator (subtract because -1 = true in forth)
  loop              \ end the loop
  nip nip           \ remove extra values from the stack
;                   \ end the word definition

\ Main function 
: f                 \ start a new word definition
  2dup              \ duplicate the string address and length
  '/ c >r           \ count the number of '/' characters and stick the result on the return stack
  2dup '- c 2/      \ count the number of '-' characters and divide by 2
  -rot 'o c         \ move the string to the top of the stack and count the number of 'o characters
