### 1. Requesting submissions for Exercism track

I've cooked up examples for the hamming, isogram, leap and raindrops tasks as defined in my copy of the Task descriptions. I don't expect you to write the full folder tree for a task, just the public function. Whatever you submit should pass all the tests. If it doesn't, I'll let you know. And if you are going to write the tests, they must follow those in each task's canonical-data.json file. Code can be left here or emailed to bruceax at gmail dot com.

As a for instance, Greg gave me the following for the isogram task:

include std/sequence.e include std/sort.e include std/text.e public function isogram( sequence str ) str = filter( str, STDFLTR_ALPHA ) str = sort( upper(str) ) for i = 2 to length( str ) do if str[i] = str[i-1] then return 0 end if end for return 1 end function

It made my first attempt look very pedestrian.

I need at least 20 working tasks before I can launch the track. After that there are documentation requirements and a CI workflow. But let's get the tasks going first.

At this point I'm not taking on Phix. I'll mention it in the documentation but that's as far as I'm prepared to take it at this point. Suitably motivated Phix users could create a Phix track. I'd be happy to help with that, just not lead it.

Finally, the code I've written thus far is on github. Bouquets and brickbats are appreciated.

"This application will be able to read your private email addresses."

That's the first thing I see when I go to sign up for exercism. It's also the last thing. Not interested in them reading *anything* on my computer.

Fair call. It'd be nice if they'd explain that. In a world of bad actors you'd think they could write a better script.

Okay, this link to the Problem Descriptions is on github and does not require any giving away of personal details to access. Choose one or two. I need at least 20 in all and I've already go solutions for hamming, hello-world, isogram, leap, raindrops and phone-number.

"This application will be able to read your private email addresses."

I did take up the case with the Exercism admins. This is their response:

This is how GitHub oauth works. If you sign up with GitHub, GitHub gives us your email address. I think theyâ€™ve entirely misunderstood whatâ€™s going on here. Itâ€™s not like we can then magically read things on their computerâ€¦

Regardless, thatâ€™s language on GitHubâ€™s side, not ours, so Iâ€™m going to mark this as wontfix.

Hey, if irv doesn't want to share his github email with the iHID folks, that should be his choice.

Would be nice if they could let you sign up with a custom (read: throwaway) email address, instead of requiring Github (which would require creating a throwaway Github account with a throwaway email).

Hey, if irv doesn't want to share his github email with the iHID folks, that should be his choice.

And it is.

Anyway, irv doesn't need to create an Exercism or Github account to contribute code. All he needs to do is read the publicly accessible task description, write some code, and send it to me. I'll take care of folding it into the framework.

By the way @petelomax , I did notice a certain phixation in some of your code, like "for i,c in" and "string". Even so, thanks.

So I've completed 20 tasks, viz

acronym anagram bob collatz-conjecture darts grains hamming hello-world isbn-verifier isogram leap luhn pangram pythagorean-triplets raindrops roman-numerals sum-of-multiples triangle two-fer yacht

That's the minimum. I will, eventually, add the rest of Pete's contributions. There are lots of others if anyone's interested. I'm now moving on to the CI and the documentation. I expect that'll be done in a few weeks time after which the launch of the learning track will occur.

Suitably motivated folk may wish to critique the postings. That'd be VERY helpful.
