Select Featured Exercises for December Diversions

Exercism
1

Next month (December), will have a relatively unstructured theme, where we feature five languages that didn’t feature in previous months:

  • ColdFusion
  • Groovy
  • Lua
  • Vimscript
  • Wren

The current list of implemented exercises looks as follows:

Doing a quick pass, I quite like these exercises:

  • flatten-array
  • run-length-encoding
  • meetup (one of our only date-related exercises)
  • kindergarten-garden
  • grade-school

And it also quite like:

  • perfect-numbers
  • dnd-character
  • food-chain

Thoughts?

For this selection of exercises, here’s the currently configured difficulty where they’ve been implemented:

exercise cfml groovy lua vimscript wren
flatten-array 1 5 5 . 3
run-length-encoding . 5 5 . 4
meetup . . . . .
kindergarten-garden . . 5 . .
grade-school . . 4 . 5
perfect-numbers . 3 3 . .
dnd-character . . . . 2
food-chain . . 3 . .

We’re in kind of the mid-tier of difficulty with this selection. Some of the perhaps easier exercises that are still unclaimed for 12in23: all-your-base (and it’s predecessors binary/trinary/octal/hexadecimal); queen-attack; strain; the resistor-color trilogy.

I’ll certainly jump in where needed. @colinleach has already put his name forward for CFML

Does vimscript have any active maintainers?

@kotp maintains Vim script. I’m in the middle of porting a few exercises there so I can probably pivot to the ones we need.

4

For CFML, every exercise except markdown is configured as difficulty 1. My guess is that the algorithm was “I’ll think about it later”, and later never arrived.

I already had all-your-base and queen-attack on my list of things to add to CF, regardless of 12in23. Not sure about resistor-color, which featured in Nibbly November (doing it in MIPS left a few mental scars, in my case).

Ah, right. I missed that it already happened in the future ;)

“For a given value of November…”

Here would be my picks.

exercise cfml groovy lua vimscript wren
all-your-base :x: :white_check_mark: :white_check_mark: :x: :x:
dnd-character :x: :x: :x: :x: :white_check_mark:
flatten-array :white_check_mark: :white_check_mark: :white_check_mark: :x: :white_check_mark:
queen-attack :x: :x: :white_check_mark: :x: :white_check_mark:
run-length-encoding :x: :white_check_mark: :white_check_mark: :x: :white_check_mark:

Since Colin already wanted to do all-your-base and queen-attack, CFML just needs to pick up two exercises. dnd-character should hopefully be an easy exercise to port for the four tracks.

This puts the most load on Vim script, but I’m a little light right now since Adrien has been helping port Racket exercises the last few days for Hacktoberfest.

8

These seem like nice options. @glennj what do you think of these?

I like 'em

Okay, I’ll get to work on dnd-character, flatten-array, and run-length encoding next week.

For Vim script, PRs have been opened for flatten-array and queen-attack, and Victor is working on a draft PR for run-length-encoding. I’ll have the last two done in about a week.

Claiming dnd-character for groovy if no one else has it.

@keiraville I see you’ve been contributing to Lua recently. Do you feel like doing D&D Character to fill in the gap for December?

16

Sure, I’ll take Lua D&D Character.

All the CFML exercises are now submitted. Erik already merged queen-attack and run-length-encoding. I just PR’d the remaining two:

For Vim script, dnd-character is going through code review, and I should have a final draft for Victor this weekend. He’s still working on run-length-encoding.

For Vim script, dnd-character is done. We’re still working on run-length-encoding.
