We need to shorten the following long lines in lessons (based on make lesson-check-all).
Please feel free to submit PRs and reference this issue (use #498).

- [ ] ./CONTRIBUTING.md:
(Out of scope: has to be fixed in carpentries/style)

Just for my own learning, why is it important to limit the lines to 100 characters? Is it about readability of the code? Are there other formatting conventions I should keep in mind?

[doctornerdis]

Also, please ignore #519. I forgot to delete my old fork before I started work on the new file.

Just for my own learning, why is it important to limit the lines to 100 characters?

git tracks changes on a line-by-line basis, so if you change a single character in a 5000 character-long paragraph written as a single line, it will highlight the entire line. Moreover, it will show it twice (original and changed version). And single line breaks are not a problem for Markdown... so, there is really no benefit in using long lines as shorter ones make life much easier.

Why exactly 100? This number is more-or-less arbitrary. People usually choose the number of characters that fit in their text editor without wrapping to the next (virtual) line. "100" is hard-coded into lesson-check and, honestly, I don't care about its exact value as long as it is reasonable: not too small, not too large... it could be 78, 83, 94, etc.

Also, please ignore #519. I forgot to delete my old fork before I started work on the new file.

Um... ok, but we need to talk :) You should use branches for pull requests:

git checkout -f gh-pages
git pull origin gh-pages

git branch mybranch
git checkout mybranch
# make changes
git add -u
git commit
git push <your-fork>

git checkout gh-pages
# submit pull-request on GitHub

Thanks for the explanation @maxim-belkin!

Don't I need permission to access this repository in order to make branches? I'm working from the GitHub desktop client, so do I need to work in git directly?

[maxim-belkin]

Um, to create branches in this repository one has to have proper permissions, but you don't need these.
The way it works is as follows:

1. you fork this repository. Your fork will be here https://github.com/doctornerdis/python-novice-inflammation
2. You clone your fork to your computer git clone https://github.com/doctornerdis/python-novice-inflammation
3. You create a new branch for your changes: git checkout -b my-changes
4. You make changes to files, then git add -u, git commit
5. You push your branch to your fork git push
6. You submit a PR on GitHub using this branch

To keep your fork up-to-date, you do:

git checkout gh-pages
git add swcarpentry https://github.com/swcarpentry/python-novice-inflammation  ## only once per repository
git fetch swcarpentry
git merge --ff-only
git push

Oh, and I now see that you've already deleted your fork that you used to submit #520. There is a better way! :)

[doctornerdis]

OK, I think I'm getting the hang of it now. I just did another PR (#521). Is that the right workflow?

[maxim-belkin]

Yep! Just don't forget to switch back to gh-pages before creating a branch for your next PR

git checkout gh-pages
git pull swcarpentry ## just in case
git checkout -b my-next-pr

Hi @maxim-belkin , may be worth ticking off the lessons that have been done from the issue description at the top of this page, to make it clearer to newcomers which are left to do

[maxim-belkin]

Thank you for the reminder, @MikeAllawayBham!

I just opened #565 to help address this ! I did have one question, though -- is the Code of Conduct still in need of definitions ? It seems to be rendering correctly, but I might have misunderstood the concern !

[maxim-belkin]

Thank you for the PR, @emdupre! I've updated the original post with the current list of issues. Regarding Code of Conduct - I think the issue was solved in 51293be...

[katkoler]

Hi, I'd like to help with this.
Is there a good way of testing it renders correctly?

[maxim-belkin]

Hi, @katkoler. If you've got macOS or Linux, make serve (or jekyll serve or bundle exec jekyll serve) will render the site for you and you will be able to check it out at http://127.0.0.1:4000.
If you're on a Windows machine make docker-serve.

[katkoler]

@maxim-belkin thanks! I'll just check that everything looks okay and open a pull request.
