Bug description

I recognized that files processed by jekyll seem to omit all line breaks. E.g., the robots.txt is now invalid.

How to reproduce the bug

Look into https://alshedivat.github.io/al-folio/robots.txt

It should be

User-agent: *
Disallow:

Sitemap:  https://alshedivat.github.io/al-folio/sitemap.xml

but is

User-agent: * Disallow: Sitemap: https://alshedivat.github.io/al-folio/sitemap.xml

Error messages and logs

What operating system are you using?

Not applicable (e.g. you're using GitHub Pages or other hosting)

Deployed site

Can you check if running locally the robots.txt file also looks like this?

If it does, this will be difficult to solve, and I will have to think about that.

If it doesn't, then jekyll-minifier can be the one to blame, since it minifies some of the files. One possible solution would be to uncomment this line, but keeping only robots.txt:

al-folio/_config.yml

Line 235 in 6b00edc

# exclude: ["robots.txt", "assets/js/search/*.js"]

It this doesn't solve it, maybe jekyll-terser is the culprit. If this is the case, we must check how to exclude robots.txt from minification.

If even this doesn't solve, it is jekyll itself that minifies this file when running with JEKYLL_ENV=production. Then, again, we will have to think of another solution.

I tested all in the docker image amirpourmand/al-folio:v0.13.4

• If I run bundle exec jekyll build the robots.txt is broken
• If I delete _site and run bundle exec jekyll serve and look into _site/robots.txt it's also broken.

If I use JEKYLL_ENV=development, everything works fine

Uncommenting the line

al-folio/_config.yml

Line 235 in 6b00edc

# exclude: ["robots.txt", "assets/js/search/*.js"]

also works. However, there might be more files to be excluded here that I'm not aware of.

In case we find more, we can always make more changes. Can you submit a PR with this change?

[dfuchss]

I will create one
