## 0.14.0

### Added

- New [`tool.shell`](docs/tool-shell.md) configuration key to set a custom shell
  (contributed by [@lsvmello](https://github.com/zk-org/zk/pull/302)).
- New [`notebook.dir`](docs/config-notebook.md) configuration key to set the
  default notebook (contributed by
  [@lsvmello](https://github.com/zk-org/zk/pull/304)).

### Changed

- The `note.ignore` configuration property was renamed to `note.exclude`, to be
  more consistent with the CLI flags.

### Fixed

- Fixed LSP positions using UTF-16 offsets (contributed by
  [@wrvsrx](https://github.com/zk-org/zk/pull/317)).

## 0.13.0

### Added

- LSP:
  - `zk.new` now returns the created note's content in its output (`content`),
    and has two new options:
    - `dryRun` will prevent `zk.new` from creating the note on the file system.
    - `insertContentAtLocation` can be used to insert the created note's content
      into an arbitrary location.
  - A new `zk.link` command to insert a link to a given note (contributed by
    [@psanker](https://github.com/zk-org/zk/pull/284)).

## 0.12.0

### Added

- LSP: Support for external URLs with `documentLink`.
- New `{{date}}` template helper to obtain a date object from natural language
  (contributed by [@zalegrala](https://github.com/zk-org/zk/pull/262)).

  ```
  Get a relative date using natural language:
  {{date "next week"}}

  Format a date returned by `get-date`:
  {{format-date (date "monday") "timestamp"}}
  ```

- `zk list` now support multiple `--match`/`-m` flags, which allows to search
  for several tokens appearing in any order in the notes (contributed by
  [@rktjmp](https://github.com/zk-org/zk/pull/268)).

### Changed

- **Breaking change:** The `{{date}}` template helper was renamed to
  `{{format-date}}`. You might need to update your configuration and templates.

### Fixed

- [#243](https://github.com/zk-org/zk/issues/243) LSP: Fixed finding backlink
  references for notes in a folder.
- [#254](https://github.com/zk-org/zk/issues/254) Fixed SQL error when pairing
  `--link-to` and `--linked-by`.

## 0.11.1

### Changed

- `zk new` now requires the `--interactive`/`-i` flag to read the note body from
  a pipe or standard input.
  [See rational](https://github.com/zk-org/zk/pull/242#issuecomment-1182602001).

### Fixed

- [#244](https://github.com/zk-org/zk/issues/244) Fixed `zk new` waiting for
  `Ctrl-D` to proceed (contributed by
  [@pkazmier](https://github.com/zk-org/zk/pull/242)).

## 0.11.0

### Added

- Use regular expressions when searching for notes with `--match`.
  ```sh
  # Find notes containing emails.
  $ zk list --match-strategy re --match ".+@.+"
  $ zk list -Mr -m ".+@.+"
  ```

### Changed

- The flags `--exact-match`/`-e` are deprecated in favor of
  `--match-strategy exact`/`-Me`.

### Deprecated

- The LSP server does not support resolving a wiki link to a note title anymore.
  - For example, `[[Planet]]` can match a note with filename `i4w0 Planet.md`
    but not `i4w0.md` with a Markdown title `Planet` anymore.
  - This "smart" fallback resolution based on note titles was too fragile and
    not supported by the `zk` CLI.

### Fixed

- [#233](https://github.com/zk-org/zk/issues/233) Hide index progress in
  non-interactive shells.
- [#235](https://github.com/zk-org/zk/issues/235) Fix LSP link recognition with
  unicode (contributed by [@zkbpkp](https://github.com/zk-org/zk/issues/235)).
- [#236](https://github.com/zk-org/zk/issues/236) Fix updating links after
  creating a new note.
- [#239](https://github.com/zk-org/zk/discussions/239) Support standard input
  via shell redirection with `zk new`.

## 0.10.1

### Changed

- Removed the dependency on `libicu`.

### Fixed

- Indexed links are now automatically updated when adding a new note, if it is a
  better match than the previous link target.

## 0.10.0

### Added

- New `--date` flag for `zk new` to set the current date manually.
- New `--id` flag for `zk new` to skip ID generation and use a provided value
  (contributed by [@skbolton](https://github.com/zk-org/zk/pull/183)).
- [#144](https://github.com/zk-org/zk/issues/144) LSP auto-completion of YAML
  frontmatter tags.
- [zk-nvim#26](https://github.com/zk-org/zk-nvim/issues/26) The LSP server
  doesn't use `additionalTextEdits` anymore to remove the trigger characters
  when completing links.
  - You can customize the default behavior with the
    [`use-additional-text-edits` configuration key](docs/config-lsp.md).
- [#163](https://github.com/zk-org/zk/issues/163) Use the `ZK_SHELL` environment
  variable to override the shell for `zk` only.
- [#173](https://github.com/zk-org/zk/issues/173) Support for double star
  globbing in `note.ignore` config option.
- [#137](https://github.com/zk-org/zk/issues/137) Customize the `fzf` options
  used by `zk`'s interactive modes with the [`fzf-options`](docs/tool-fzf.md)
  config option (contributed by
  [@Nelyah](https://github.com/zk-org/zk/pull/154)).

- [#168](https://github.com/zk-org/zk/discussions/168) Customize the `fzf` key
  binding to create new notes with the [`fzf-bind-new`](docs/tool-fzf.md) config
  option.

### Changed

- The default `fzf` key binding to create a new note with
  `zk edit --interactive` was changed to `Ctrl-E`, to avoid conflict with the
  default `Ctrl-N` binding.

### Fixed

- [#126](https://github.com/zk-org/zk/issues/126) Embedded image links shown as
  not found.
- [#152](https://github.com/zk-org/zk/issues/152) Incorrect timezone for natural
  dates.
- [#170](https://github.com/zk-org/zk/issues/170) Broken wiki links in
  subdirectories.
- [#185](https://github.com/zk-org/zk/issues/185) Don't parse a Markdown table
  header as a colon tag.

## 0.9.0

### Added

- New LSP commands:
  - [`zk.list`](docs/editors-integration.md#zklist) to search for notes.
  - [`zk.tag.list`](docs/editors-integration.md#zktaglist) to retrieve the list
    of tags.
- `--debug` mode which prints a stacktrace on `SIGINT`.

### Fixed

- [#111](https://github.com/zk-org/zk/issues/111) Filenames take precedence over
  folders when matching a sub-path with wiki links.
- [#118](https://github.com/zk-org/zk/issues/118) Fix infinite loop when parsing
  a single-character hashtag.
- [#121](https://github.com/zk-org/zk/issues/121) Take into account the
  `--no-input` flag with `zk init`.
- [#120](https://github.com/zk-org/zk/discussions/120) Support RFC 3339 dates
  with the time flags (e.g. `--created-before`).

## 0.8.0

### Added

- New `zk graph --format json` command which produces a JSON graph of the notes
  matching the given criteria.
- New template variables `filename` and `filename-stem` when formatting notes
  (e.g. with `zk list --format`) and for the [`fzf-line`](docs/tool-fzf.md)
  config key.
- Customize how LSP completion items appear in your editor when auto-completing
  links with the [`[lsp.completion]` configuration section](docs/config-lsp.md).
  ```toml
  [lsp.completion]
  # Show the note title in the completion pop-up, or fallback on its path if empty.
  note-label = "{{title-or-path}}"
  # Filter out the completion pop-up using the note title or its path.
  note-filter-text = "{{title}} {{path}}"
  # Show the note filename without extension as detail.
  note-detail = "{{filename-stem}}"
  ```
- New `--dry-run` flag for `zk new` which prints out the path and content of the
  generated note instead of saving it to the file system.
- New `--verbose` flag for `zk index` which prints detailed information about
  the indexing process.
- You can now filter through the [YAML frontmatter](docs/note-frontmatter.md)
  with `zk list --interactive`.

### Fixed

- [#89](https://github.com/zk-org/zk/issues/89) Calling `zk index` from outside
  the notebook (contributed by
  [@adamreese](https://github.com/zk-org/zk/pull/90)).
- [#98](https://github.com/zk-org/zk/issues/98) Index wiki links using partial
  paths for `--linked-by` and `--link-to`.
- [#98](https://github.com/zk-org/zk/issues/98) Ignore spaces around the pipe in
  wiki links for LSP diagnostics.

## 0.7.0

### Added

- List the tags found in your notebook with `zk tag list`.
  - Many options are available to customize the output, including JSON
    serialization. See `zk tag list --help`.
- Support for LSP references to browse the backlinks of the current note, if the
  caret is not over a link.
- New template variables are available when
  [generating custom Markdown links with `link-format`](docs/note-format.md).
  - `filename`, `path`, `abs-path` and `rel-path` for many path flavors.
  - `metadata` to use information (e.g. `id`) from the YAML frontmatter.
- The LSP server is now matching wiki links to any part of a note's path or its
  title.
  - Given the note `book/z5mj Information Graphics.md` with the title "Book
    Review of Information Graphics", the following wiki links would work from a
    note located under `journal/2020-09-25.md`:
    ```markdown
    [[../book/z5mj]] [[book/z5mj]] [[z5mj]] [[book review information]]
    [[Information Graphics]]
    ```
- Use the `{{abs-path}}` template variable when
  [formatting notes](docs/template-format.md) to print the absolute path to the
  note (contributed by [@pstuifzand](https://github.com/zk-org/zk/pull/60)).
- A new `{{substring s index length}}` template helper extracts a portion of a
  given string, e.g.:
  - `{{substring 'A full quote' 2 4}}` outputs `full`
  - `{{substring 'A full quote' -5 5}` outputs `quote`

### Fixed

- UTF-8 handling in the LSP server.
- [#78](https://github.com/zk-org/zk/issues/78) Do not exclude notes containing
  broken links from the index.
- Allow setting the `--working-dir` and `--notebook-dir` flags before the `zk`
  subcommand when using aliases, e.g. `zk -W ~/notes my-alias`.
- [#86](https://github.com/zk-org/zk/issues/86) Index encoded Markdown links.

## 0.6.0

### Added

- Use JSON formats with `zk list` for easy post-processing:
  - `--format json` prints a plain JSON array.
  - `--format jsonl` prints one JSON note object per line, according to
    [JSON Lines](https://jsonlines.org/).
- The new `{{json}}` template helper serializes any template context variable
  into a valid JSON value, e.g.:
  - `{{json title}}` prints with quotes `"An interesting note"`
  - `{{json .}}` serializes the full template context as a JSON object.
- Use `--header` and `--footer` options with `zk list` to print arbitrary text
  at the start or end of the list.
- Support for LSP references to browse the backlinks of the link under the caret
  (contributed by [@pstuifzand](https://github.com/zk-org/zk/pull/58)).
- New [`note.ignore`](docs/config-note.md) configuration option to ignore files
  matching the given path globs when indexing notes.
  ```yaml
  [note]
  ignore = [
      "log-*.md"
      "drafts/*"
  ]
  ```

### Fixed

- [#16](https://github.com/zk-org/zk/issues/16) Links with section anchors, e.g.
  `[[filename#section]]`.
- Unicode support in wiki links. If you use accents or ideograms, please run
  `zk index --force` after upgrading to fix your index.

## 0.5.0

### Added

- [Editor integration through LSP](https://github.com/zk-org/zk/issues/22):
  - New code actions to create a note using the current selection as title.
  - Custom commands to
    [run `new` and `index` from your editor](docs/editors-integration.md#custom-commands).
  - Diagnostics to [report dead links or wiki link titles](docs/config-lsp.md).
  - Auto-complete only the path of a Markdown link by typing `[custom title]((`.
- Customize the format of `fzf`'s lines
  [with your own template](docs/tool-fzf.md).
  ```toml
  [tool]
  fzf-line = "{{style 'green' path}}{{#each tags}} #{{this}}{{/each}} {{style 'black' body}}"
  ```

### Changed

- Automatically index the notebook when saving a note with an LSP-enabled
  editor.
  - This ensures that tags and notes auto-completion lists are up-to-date.

### Fixed

- Creating a new note from `fzf` in a directory containing spaces.
- Fix completion with Neovim's built-in LSP client (contributed by
  [@cormacrelf](https://github.com/zk-org/zk/pull/39)).

## 0.4.0

### Added

- Interactive wizard for the `zk init` command.
- An experimental Language Server for LSP-compatible editors:
  - Auto-complete Markdown links with `[[` (setup wiki links in the
    [note formats configuration](docs/note-format.md))
  - Auto-complete [hashtags and colon-separated tags](docs/tags.md).
  - Preview the content of a note when hovering a link.
  - Navigate in your notes by following internal links.
  - [And more to come...](https://github.com/zk-org/zk/issues/22)
  - See [the documentation](docs/editors-integration.md) for configuration
    samples.
- Pair `--match` with `--exact-match` / `-e` to search for (case insensitive)
  exact occurrences in your notes.
  - This can be useful when looking for terms including special characters, such
    as `[[name]]`.
- Generating links to notes.
  - Use the `{{link}}` template variable when
    [formatting notes](docs/template-format.md) to print a link to the note,
    relative to the working directory.
  - Use the `{{format-link path title}}` template helper to render a custom
    link.
  - Customize the link format from the
    [note formats settings](docs/note-format.md). You can for example choose
    regular Markdown links, wiki links or a custom format.

### Changed

- The local configuration file (`.zk/config.toml`) is not required anymore in a
  notebook's `.zk` directory.
- `--notebook-dir` does not change the working directory anymore, instead it
  sets manually the current notebook and disable auto-discovery. Use the new
  `--working-dir`/`-W` flag to run `zk` as if it was started from this path
  instead of the current working directory.
  - For convenience, `ZK_NOTEBOOK_DIR` behaves like setting a `--working-dir`
    fallback, instead of `--notebook-dir`. This way, paths will be relative to
    the root of the notebook.
  - A practical use case is to use `zk list -W .` when outside a notebook. This
    will list the notes in `ZK_NOTEBOOK_DIR` but print paths relative to the
    current directory, making them actionable from your terminal emulator.

## 0.3.0

### Added

- Global `zk` configuration at `~/.config/zk/config.toml`.
  - Useful to share aliases or default settings across several
    [notebooks](docs/notebook.md).
  - This is the same format as a notebook [configuration file](docs/config.md).
  - Shared templates can be stored in `~/.config/zk/templates/`.
  - `XDG_CONFIG_HOME` is taken into account.
- Use `--notebook-dir` or set `ZK_NOTEBOOK_DIR` to run `zk` as if it was started
  from this path instead of the current working directory.
  - This allows running `zk` without being in a notebook.
  - By setting `ZK_NOTEBOOK_DIR` in your shell configuration file (e.g.
    `~/.profile`), you are declaring a default global notebook which will be
    used when `zk` is not in a notebook.
  - When the notebook directory is set explicitly, any path given as argument
    will be relative to it instead of the actual working directory.
- Find every note whose title is mentioned in the note you are working on with
  `--mentioned-by file.md`.
  - To refer to a note using several names, you can use the
    [YAML frontmatter key `aliases`](https://publish.obsidian.md/help/How+to/Add+aliases+to+note).
    For example the note titled "Artificial Intelligence" might have:
    `aliases: [AI, robot]`
  - To find only unlinked mentions, pair it with `--no-linked-by`, e.g.
    `--mentioned-by file.md --no-linked-by file.md`.
- Declare [named filters](docs/config-filter.md) in the configuration file to
  reuse [note filtering options](docs/note-filtering.md) used frequently
  together, for example:
  ```toml
  [filter]
  recents = "--sort created- --created-after 'last two weeks'"
  ```
  ```sh
  $ zk list recents --limit 10
  $ zk edit recents --interactive
  ```

### Fixed

- [#4](https://github.com/zk-org/zk/issues/4) Terminal borked when piping
  content with Vim

## 0.2.1

### Fixed

- Looking for mentions of a note with a title containing double quotes.
- Crash when parsing certain link snippets.

## 0.2.0

### Added

- Support for tags.
  - Filter notes by their tags using `--tag "history, europe"`.
    - To match notes associated with either tags, use a pipe `|` or `OR` (all
      caps), e.g. `--tag "inbox OR todo"`.
    - If you want to exclude notes having a particular tag, prefix it with `-`
      or `NOT` (all caps), e.g. `--tag "NOT done"`.
    - Use glob patterns to match multiple tags, e.g. `--tag "book-*"`.
  - Many tag flavors are supported: `#hashtags`, `:colon:separated:tags:`
    ([opt-in](docs/note-format.md)) and even Bear's
    [`#multi-word tags#`](https://blog.bear.app/2017/11/bear-tips-how-to-create-multi-word-tags/)
    ([opt-in](docs/note-format.md)). If you prefer to use a YAML frontmatter,
    list your tags with the key `tags` or `keywords`.
- Find every mention of a note in your notebook with `--mention file.md`.
  - This will look for occurrences of the note's title in other notes.
  - To refer to a note using several names, you can use the
    [YAML frontmatter key `aliases`](https://publish.obsidian.md/help/How+to/Add+aliases+to+note).
    For example the note titled "Artificial Intelligence" might have:
    `aliases: [AI, robot]`
  - To find only unlinked mentions, pair it with `--no-link-to`, e.g.
    `--mention file.md --no-link-to file.md`.
- Print metadata from the [YAML frontmatter](docs/note-frontmatter.md) in `list`
  output using `{{metadata.<key>}}`, e.g. `{{metadata.description}}`. Keys are
  normalized to lower case.
- Use the YAML frontmatter key `date` for the note creation date, when provided.
- Access environment variables from note templates with the `env.<key>` template
  variable, e.g. `{{env.PATH}}`.

### Changed

- Renamed `--linking-to` filtering option to `--link-to`.
- Multiple `--extra` variables are now separated by `,` instead of `;`.
