I noticed that the CI badge was failing and it seems to be caused by the fact that it reflects the latest build including PRs. This change filters the events to only "push events on the master branch" so the badge stays green even if a PR fails.
* ui: improve menu folding
Fold/unfold the menu bar just by the amount of scroll, not by its
full width
* refactor: use a variable for the menu bar height
* Fix menu scroll jittering, remove hover folding smoothness
Rewrite it to use `position:` `sticky` and `relative` instead
of continuous programmatic position changes
On-hover folding-unfolding transition removal is a side-effect
This prevents recursive copy-loops when the destination directory
is contained in the source directory.
Now it bails out with a descriptive error message.
Html page title for every chapter in the book is created by the following code:
```rust
let title: String;
{
let book_title = ctx
.data
.get("book_title")
.and_then(serde_json::Value::as_str)
.unwrap_or("");
title = ch.name.clone() + " - " + book_title;
}
```
If the `book.toml` file is missing, and `book_title` parameter is empty, there's an awkward ` - ` string hanging at the end of each chapter's title.
This PR adds a `match` case to handle that kind of situation.
* Using .to_lowercase() on the theme matching to avoid needed exact capitolization in the book.toml
* Changed the default-dark-theme from .to_string() to .to_lowercase() to match theme
Doing what it says results in:
```
