This is a squashed commit. It roughly encompasses the following changes.
---
\# Book
- Created another private submodule, mdbook::loader::book
- This submodule contains the data types representing a Book
- For now the Book just contains a list of BookItems (either chapters or
separators)
- A Chapter contains its name, contents (as one long string), an
optional section number (only numbered chapters have numbers,
obviously), and any nested chapters
- There's a function for loading a single Chapter from disk using it's
associated Link entry from the SUMMARY.md
- Another function builds up the Book by recursively visiting all Links
and separators in the Summary and joining them into a single
Vec<SummaryItem>. This is the only non-dumb-data-type item which is
actually exported from the book module
\# Loader
- Made the loader use the book::load_book_from_disk function for
loading a book in the loader's directory.
\# Tests
- Made sure you can load from disk by writing some files to a temporary
directory
- Made sure the Loader can load the entire example-book from disk and
doesn't crash or hit an error
- Increased test coverage from 34.4% to 47.7% (as reported by cargo
kcov)
From the [pull request comment][pr], here's a rough summary of what
was done in the squashed commits.
---
\# Summary Parser
- Added a private submodule called `mdbook::loader::summary` which
contains all the code for parsing `SUMMARY.md`
- A `Summary` contains a title (optional), then some prefix, numbered,
and suffix chapters (technically `Vec<SummaryItem>`)
- A `SummaryItem` is either a `Link` (i.e. link to a chapter), or a
separator
- A `Link` contains the chapter name, its location relative to the
book's `src/` directory, and a list of nested `SummaryItems`
- The `SummaryParser` (a state machine-based parser) uses
`pulldown_cmark` to turn the `SUMMARY.md` string into a stream of
`Events`, it then iterates over those events changing its behaviour
depending on the current state,
- The states are `Start`, `PrefixChapters`, `NestedChapters(u32)` (the
`u32` represents your nesting level, because lists can contain lists),
`SuffixChapters`, and `End`
- Each state will read the appropriate link and build up the
`Summary`, skipping any events which aren't a link, horizontal rule
(separator), or a list
\# Loader
- Created a basic loader which can be used to load the `SUMMARY.md` in
a directory.
\# Tests
- Added a couple unit tests for each state in the parser's state
machine
- Added integration tests for parsing a dummy SUMMARY.md then asserting
the result is exactly what we expected

This commit changes the url used to call the playground, and the
request parameter format to go with it. The older evaluate is
available in the playground as a form of backwards compatibility
and swithcing now opens way for using newer features.
On the web, the normalized path separator is forward-slash (`/`), so we
use the built-in `is_separator()` method to replace any path separator
with the forward-slash, to ensure consistent output on unix and windows
machines.
