This removes mdBook in favor of a flat docs folder generating a single
`README.md` in the repository root.
Installation and usage instructions have also been expanded slightly.
Add support for postprocessing of Markdown prior to writing converted
notes to disk.
Postprocessors may be used when making use of Obsidian export as a Rust
library to do the following:
1. Modify a note's `Context`, for example to change the destination
filename or update its Frontmatter.
2. Change a note's contents by altering `MarkdownEvents`.
3. Prevent later postprocessors from running or cause a note to be
skipped entirely.
Future releases of Obsidian export may come with built-in postprocessors
for users of the command-line tool to use, if general use-cases can be
identified.
For example, a future release might include functionality to make notes
more suitable for the Hugo static site generator. This functionality
would be implemented as a postprocessor that could be enabled through
command-line flags.
A recent Obsidian update expanded the list of allowed characters in
filenames, which now includes `?` as well. This needs to be
percent-encoded for proper links in static site generators like Hugo.
Notes with an underscore would fail to be recognized within Obsidian
`[[_WikiLinks]]` due to the assumption that the underlying Markdown
parser (pulldown_cmark) would emit the text between [[ and ]] as a
single event.
The note parser has now been rewritten to use a more reliable state
machine which correctly recognizes this corner-case (and likely some
others).
Previously, `filter_fn` on the `WalkOptions` struct looked like:
pub filter_fn: Option<Box<&'static FilterFn>>,
This boxing was unneccesary and has been changed to:
pub filter_fn: Option<&'static FilterFn>,
This will only affect people who use obsidian-export as a library in
other Rust programs, not users of the CLI.
For those library users, they no longer need to supply `FilterFn`
wrapped in a Box.
This commit fixes a bug where, if a note contained uppercase characters
(for example `Note.md`) but was referred to using lowercase
`(`[[note]]`), that note would not be found.
It's possible to end up with "recursive embeds" when two notes embed
each other. This happens for example when a `Note A.md` contains
`![[Note B]]` but `Note B.md` also contains `![[Note A]]`.
By default, this will trigger an error and display the chain of notes
which caused the recursion.
Using the new `--no-recursive-embeds`, if a note is encountered for a
second time while processing the original note, rather than embedding it
again a link to the note is inserted instead to break the cycle.

By default hidden files, patterns listed in `.export-ignore` as well as
any files ignored by git are excluded from exports. This behavior has
been made configurable on the CLI using the new flags `--hidden`,
`--ignore-file` and `--no-git`.
