# Changelog

## v0.6.0 (2021-02-15)

### New

* Add `--version` flag. \[Nick Groenen]

### Changes

* Don't Box FilterFn in WalkOptions. \[Nick Groenen]
  
  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.

### Fixes

* Recognize notes beginning with underscores. \[Nick Groenen]
  
  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).

* Support self-references. \[Joshua Coles]
  
  This ensures links to headings within the same note (`[[#Heading]]`)
  resolve correctly.

### Other

* Avoid redundant "Release" in GitHub release titles. \[Nick Groenen]

* Add failing testcase for files with underscores. \[Nick Groenen]

* Add unit tests for display of ObsidianNoteReference. \[Nick Groenen]

* Add some unit tests for ObsidianNoteReference::from_str. \[Nick Groenen]

* Also run tests on pull requests. \[Nick Groenen]

* Apply clippy suggestions following rust 1.50.0. \[Nick Groenen]

* Fix infinite recursion bug with references to current file. \[Joshua Coles]

* Add tests for self-references. \[Joshua Coles]
  
  Note as there is no support for block references at the moment, the generated link goes nowhere, however it is to a reasonable ID

## v0.5.1 (2021-01-10)

### Fixes

* Find uppercased notes when referenced with lowercase. \[Nick Groenen]
  
  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.

## v0.5.0 (2021-01-05)

### New

* Add --no-recursive-embeds to break infinite recursion cycles. \[Nick Groenen]
  
  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.

* Make walk options configurable on CLI. \[Nick Groenen]
  
  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`.

* Support links referencing headings. \[Nick Groenen]
  
  Previously, links referencing a heading (`[[note#heading]]`) would just
  link to the file name without including an anchor in the link target.
  Now, such references will include an appropriate `#anchor` attribute.
  
  Note that neither the original Markdown specification, nor the more
  recent CommonMark standard, specify how anchors should be constructed
  for a given heading.
  
  There are also some differences between the various Markdown rendering
  implementations.
  
  Obsidian-export uses the [slug](https://crates.io/crates/slug) crate to generate anchors which should
  be compatible with most implementations, however your mileage may vary.
  
  (For example, GitHub may leave a trailing `-` on anchors when headings
  end with a smiley. The slug library, and thus obsidian-export, will
  avoid such dangling dashes).

* Support embeds referencing headings. \[Nick Groenen]
  
  Previously, partial embeds (`![[note#heading]]`) would always include
  the entire file into the source note. Now, such embeds will only include
  the contents of the referenced heading (and any subheadings).
  
  Links and embeds of [arbitrary blocks](https://publish.obsidian.md/help/How+to/Link+to+blocks) remains unsupported at this time.

### Changes

* Print warnings to stderr rather than stdout. \[Nick Groenen]
  
  Warning messages emitted when encountering broken links/references will
  now be printed to stderr as opposed to stdout.

### Other

* Include filter_fn field in WalkOptions debug display. \[Nick Groenen]

## v0.4.0 (2020-12-23)

### Fixes

* Correct relative links within embedded notes. \[Nick Groenen]
  
  Links within an embedded note would point to other local resources
  relative to the filesystem location of the note being embedded.
  
  When a note inside a different directory would embed such a note, these
  links would point to invalid locations.
  
  Now these links are calculated relative to the top note, which ensures
  these links will point to the right path.

### Other

* Add brief library documentation to all public types and functions. \[Nick Groenen]

## v0.3.0 (2020-12-21)

### New

* Report file tree when RecursionLimitExceeded is hit. \[Nick Groenen]
  
  This refactors the Context to maintain a list of all the files which
  have been processed so far in a chain of embeds. This information is
  then used to print a more helpful error message to users of the CLI when
  RecursionLimitExceeded is returned.

### Changes

* Add extra whitespace around multi-line warnings. \[Nick Groenen]
  
  This makes errors a bit easier to distinguish after a number of warnings
  has been printed.

### Other

* Setup gitchangelog. \[Nick Groenen]
  
  This adds a changelog (CHANGES.md) which is automatically generated with
  [gitchangelog](https://github.com/vaab/gitchangelog).

## v0.2.0 (2020-12-13)

* Allow custom filter function to be passed with WalkOptions. \[Nick Groenen]

* Re-export vault_contents and WalkOptions as pub from crate root. \[Nick Groenen]

* Run mdbook hook against README.md too. \[Nick Groenen]

* Update installation instructions. \[Nick Groenen]
  
  Installation no longer requires a git repository URL now that a crate is
  published.

* Add MdBook generation script and precommit hook. \[Nick Groenen]

* Add more reliable non-ASCII tetscase. \[Nick Groenen]

* Create FUNDING.yml. \[Nick Groenen]

## v0.1.0 (2020-11-28)
