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

IIUC, the existing exclude rule has meant to do what it will do in the
future (gitignore-like matching, not glob-only matching). This fix makes
the rule to do what it was expected to do, and is forward-compatible,
therefore fixing the warning messages.
The toml crate removed its serde dependency in 0.3, but in 0.4, it
went away. Cargo didn't warn on this, but now it does. As such, we
need a release so that rust's build doesn't warn constantly.
- Replaced link parser with a Regex
- Implemented {{#include}} links
- Will display relatively nice error when cannot open {{#}} linked file
- Escaped links no longer render with escape char
- utils::fs::file_to_path no takes AsRef<Path>
- sorted export/mod in lib.rs
On `x86_64-unknown-linux-musl` it looks like travis can't compile
the `backtrace-sys` crate because the `./configure` step fails.
The error message `./configure` gives is:
configure: error: in `/home/travis/build/azerupi/mdBook/target/x86_64-unknown-linux-musl/debug/build/backtrace-sys-204dc57c91e9a514/out':
configure: error: C compiler cannot create executables
This project already had a transitive dependency on regex; let's use it.
This isn't the most efficient solution, but it should be fine. It ends
up doing five full scans of the text. There's probably an easier way but
I'm mostly just trying to get this to work for now.
This also implements the same algorithm that rustdoc does for generating
the name for the link.
