Install

1. ensure the prerequisites are installed.
   • Virtualenv
2. run ./script/setup to install the dependencies.

Note: To update the dependencies, run ./script/update

Bake a New Book

1. run ./script/fetch-html statistics
   • Note: To see the list of books available see ./books.txt
   • Note: This will require you to log in via ssh.
   • Note: You can set the ssh username by running USER=myusername ./script/fetch-html ...
   • Note: You can set the remote server to pull from by running HOST=dev.cnx.org ./script/fetch-html ...
   • Note: You can run ./script/fetch-html --all to fetch all the books
2. run ./script/bake-book statistics

You will first need to get the single-file HTML from the server (fetch-html) and then convert the single-file HTML locally into the "baked" book via bake-book. Once you have done the first part, you can run ./script/bake-book statistics to your ❤️'s content!

Add a New Book to the config

The steps to add a new book (like dark-matter-for-dummies) are:

1. Find the UUID of the book you want
   • point your browser to the server containing the book (ie cnx.org) and find a book you want.
   • click "More Information" and copy the ID
2. add an entry to ./books.txt

Test

1. run ./script/test

This will run the linter, generate sassdocs, and generate the guides to verify they work.

Documentation

Recipe documentation can be found at ./recipes/ and an example config file.

1. run ./script/generate-docs to generate the SASS Docs
2. run ./script/generate-guide statistics to generate the HTML Guide for a book
3. open the generated file in your browser

CSS Coverage

1. run ./script/fetch-html ${book_name} to fetch the Raw HTML for a book
2. run ./script/bake-book ${book_name}
3. The HTML Report should now be available at ./coverage/

You can pass 3 arguments to report-book-coverage to change how it reports coverage:

• --verbose : outputs verbose/debugging output
• --ignore-source-map : covers the CSS even if a sourceMappingURL exists.
• --cover-declarations : generates coverage based on the declarations, as well as the selector
• Note: You can run ./script/report-book-coverage --all to generate coverage using all the books

For more details on the commandline options see the css-coverage documentation.

Why CSS Coverage?

Code coverage is a great way to see if your tests exercises all the features of the codebase.

In the case of this repositoriy, the "codebase" contains all the CSS recipe files and the "tests" are the HTML snippets used to create a style guide.

By checking the code coverage, whenever a new feature in a book is added, a corresponding example in the HTML guide should be added as well (code coverage will complain otherwise).

Bake Remotely

To rebake a book on a development instance. To do that, you will need to upload a CSS recipe file, trigger a rebake, and then clear the cache.

1. run ./script/compile-books to generate the recipes CSS file

2. run ./script/bake-book-remote ${BOOK_NAME} ${VERSION} to upload, trigger, and clear the cache

   • ${BOOK_NAME] is the book’s name in the book list of /books.txt
   • ${VERSION] is the @#.## in the target collection URL

Example

For example, you want to rebake the "cooking" book:

1. you can run ./script/bake-book-remote cooking and it will tell you to go to http://foo.cnx.org/contents/${UUID}
2. find the version (ie 7.16) by looking at the URL or by clicking “More Information” at the bottom of the page
3. run ./script/bake-book-remote cooking 7.16 (using that version you found)

Regression Testing

To check that there were no regressions in a book you will need to do the following:

1. bake the book with the old code
2. bake the book with the new code
3. compare the 2 baked HTML files to see if there were any differences

Here are the steps to run it:

# Prep work (run once)
./script/setup
./script/fetch-html statistics # Or any book in ./books.txt

# Check out the old version from git (ie `master` branch)
# Then run:
./script/diff-book-prepare statistics

# Check out the new code from git (ie `shiny-unincorns` branch)
# Then run:
./script/diff-book statistics

# Any differences would pop up at this point

# Optional: Create a diff and give it to a GUI
diff ./data/statistics-prepared.xhtml ./data/statistics-baked.xhtml > foo.diff

Note: You can specify --all instead of statistics to diff all the books (after fetching them earlier)

Finding differences in the styleguide

Instead of diffing the whole book, you can find differences in the styleguide for a recipe (faster and easier to find errors because the HTML files are much smaller than an entire book).

To do this, just replace every occurrence of ./script/diff-book ${BOOK_NAME} (and ./script/diff-book-prepare) with diff-guide ${RECIPE_NAME} in the instructions above.

Experimental

To update the Documentation in the gh-pages branch:

1. git checkout master
2. ./script/generate-and-update-gh-pages

Note: This will push changes if successful
