## `bat` as a library

- Deprecate `HighlightingAssets::syntaxes()` and `HighlightingAssets::syntax_for_file_name()`. Use `HighlightingAssets::get_syntaxes()` and `HighlightingAssets::get_syntax_for_path()` instead. They return a `Result` which is needed for upcoming lazy-loading work to improve startup performance. They also return which `SyntaxSet` the returned `SyntaxReference` belongs to. See #1747, #1755, #1776, #1862 (@Enselic)
- Remove `HighlightingAssets::from_files` and `HighlightingAssets::save_to_cache`. Instead of calling the former and then the latter you now make a single call to `bat::assets::build`. See #1802, #1971 (@Enselic)
- Replace  the `error::Error(error::ErrorKind, _)` struct and enum with an `error::Error` enum. `Error(ErrorKind::UnknownSyntax, _)` becomes `Error::UnknownSyntax`, etc. Also remove the `error::ResultExt` trait. These changes stem from replacing `error-chain` with `thiserror`. See #1820 (@Enselic)
- Add new `MappingTarget` enum variant `MapExtensionToUnknown`. Refer to its documentation for more information. Also mark `MappingTarget` as `#[non_exhaustive]` since more enum variants might be added in the future. See #1703 (@cbolgiano), #2012 (@Enselic)


# v0.18.3

## Bugfixes

- Bump `git2` dependency to fix build with Rust 1.54, see #1761


# v0.18.2

## Features

- Ignore known backup/template filename suffixes when selecting the syntax, see #1687 (@scop)

## Bugfixes

- Fix for a security vulnerability on Windows. Prior to this release, `bat` would execute programs called `less`/`less.exe` from the current working directory (instead of the one from `PATH`) with priority. An attacker might be able to use this by placing a malicious program in a shared directory where the user would execute `bat`. `bat` users on Windows are advised to upgrade to this version. See #1724 and #1472 (@Ry0taK).

## Other

- Add bash completion, see #1678 (@scop)

- If `PAGER` is `bat`, silently use `less` to prevent recursion. For `BAT_PAGER` or `--pager`, exit with error, see #1413 (@Enselic)
- Manpage highlighting fix, see #1511 (@keith-hall)
- `BAT_CONFIG_PATH` ignored by `bat` if non-existent, see #1550 (@sharkdp)

## Other

## Packaging

- Compilation problems with `onig_sys` on various platforms have been resolved by upgrading to `syntect 4.2`, which includes a new `onig` version that allows to build `onig_sys` without the `bindgen` dependency. This removes the need for `libclang(-dev)` to be installed to compile `bat`. Package maintainers might want to remove `clang` as a build dependency. See #650 for more details.

# v0.15.1

## Bugfixes

- Fix highlighting of Markdown files, see #963 and #977
- Fix `base16` theme (was broken since in v0.14), see #972, #934 and #979 (@mk12).
  Users suffering from #865 ("no color for bat in ssh from a Windows client") can use the `ansi-dark` and `ansi-light` themes from now on.

## New syntaxes

- Fortran, see #957
- Email (@mariozaizar)
- QML, see #962 (@pylipp)

# v0.15.0

## Features

- Add a new `--diff`/`-d` option that can be used to only show lines surrounding
  Git changes, i.e. added, removed or modified lines. The amount of additional
  context can be controlled with `--diff-context=N`. See #23 and #940

## Bugfixes

- Error message printed in the middle of the output for another file, see #946
- Performance improvements when using custom caches (via `bat cache --build`): the `bat` startup time should now be twice as fast (@lzutao).

## Themes

- Updated version of the Solarized dark/light themes, see #941

## `bat` as a library

- There are a few changes in the "low level" API (the `Config` struct has changed and
  the error handler needs a new `&mut dyn Write` argument). The high-level API is not
  affected.

# v0.14.0

## Features

- Added a new `--file-name <name>…` option to overwrite the displayed filename(s)
  in the header. This is useful when piping input into `bat`. See #654 and #892 (@neuronull).
- Added a new `--generate-config-file` option to create an initial configuration file
  at the right place. See #870 (@jmick414)

## Bugfixes

- Performance problems with C# source code have been fixed, see #677 (@keith-hall)
- Performance problems with Makefiles have been fixed, see #750 (@keith-hall)
- Fix bug when highlighting Ruby files with unindented heredocs, see #914 (@keith-hall)
- A highlighting problem with Rust source code has been fixed, see #924 (@keith-hall)
- Windows: short files that do not require paging are displayed and then lost, see #887
- `--highlight-line` did not work correctly in combination with `--tabs=0` and `--wrap=never`,
  see #937

## Other

- When saving/reading user-provided syntaxes or themes, `bat` will now maintain a
  `metadata.yaml` file which includes information about the `bat` version which was
  used to create the cached files. When loading cached files, we now print an error
  if they have been created with an incompatible version. See #882
- Updated `liquid` dependency to 0.20, see #880 (@ignatenkobrain)

## `bat` as a library

- A completely new "high level" API has been added that is much more convenient
  to use. See the `examples` folder for the updated code. The older "low level"
  API is still available (basically everything that is not in the root `bat`
  module), but has been refactored quite a bit. It is recommended to only use
  the new "high level" API, if possible. This will be much easier to keep stable.
  Note that this should still be considered a "beta" release of `bat`-as-a-library.
  For more details and some screenshots of the example programs, see #936.
- Stripped out a lot of binary-only dependencies, see #895 and #899 (@dtolnay)

  This introduces a `features = ["application"]` which is enabled by default and pulls in
  everything required by `bat` the application. When depending on bat as a library, downstream
  `Cargo.toml` should disable this feature to cut out inapplicable heavy dependencies:
  ``` toml
  [dependencies]
  bat = { version = "0.14", default-features = false }
  ```
  Other optional functionality has also been put behind features: `paging` and `git` support.
- Allow using the library with older syntect, see #896 and #898 (@dtolnay)

## New syntaxes

- Rego, see #872 (@patrick-east)
- Stylo, see #917


# v0.13.0

## `bat` as a library

Beginning with this release, `bat` can be used as a library (#423).

This was a huge effort and I want to thank all people who made this possible: @DrSensor, @mitsuhiko, @mre, @eth-p!

- Initial attempt in #469 (@mitsuhiko)
- Second attempt, complete restructuring of the `bat` crate, see #679 (@DrSensor)
- Updates to example, public API, error handling, further refactoring: #693 #873 #875 (@sharkdp)

I want to stress that this is the very first release of the library. Things are very likely to change. A lot of things are still missing (including the documentation).

That being said, you can start using it! See the example programs in [`examples/`](https://github.com/sharkdp/bat/tree/master/examples).

You can see the API documentation here: https://docs.rs/bat/

## Features

- (**Breaking change**) Glob-based syntax mapping, see #877 and #592. With this change,
  users need to update their bat config files (`bat --config-file`), if they have any `--map-syntax` settings
  present.

  The option now works like this:
  ```bash
  --map-syntax <glob-pattern>:<syntax-name>
  ```

  For more information, see the `--help` text, the man page or the README.

  This new feature allows us to properly highlight files like:
  * `/etc/profile`
  * `~/.ssh/config`

- `--highlight-line` now accepts line ranges, see #809 (@lkalir)
- Proper wrapping support for output with wide Unicode characters, see #811 #787 and #815 (@Kogia-sima)
- A lot of updates to existing syntaxes via #644 (@benwaffle, @keith-hall)
- `BAT_CACHE_PATH` can be used to place cached `bat` assets in a non-standard path, see #829 (@neuronull)
- Support combination of multiple styles at the same time, see #857 (@aslpavel)

## Bugfixes

- Do not pass '--no-init' on newer less versions, see #749 and #786 (@sharkdp)
- 'bat cache' still takes precedence over existing files, see #666 (@sharkdp)
- `.sc` files should be treated as scala files, see #443 (@benwaffle)
- Allow underscores and dashes in page names, see #670 (@LunarLambda)
- Keep empty lines empty, see #601 (@mbarbar)
- Wrapping does not work when piping, see #758 (@fusillicode, @allevo, @gildo)

# v0.12.0

## Features

- Binary file content can now be viewed with `bat -A`, see #623, #640 (@pjsier and @sharkdp)

## Bugfixes

- Output looks unbalanced when using '--style=grid,numbers' without 'header', see #571 (@eth-p)
- issues with filenames starting with "cache", see #584
- Can't build cache with new theme without creating cache dir, see #576 (@frm)

  ![](https://camo.githubusercontent.com/c3e769482ef3184f6be6adaa34bdc8d19c378254/68747470733a2f2f692e696d6775722e636f6d2f324b54486859542e706e67)

  see #395 and #381 for more details.

  of styles from the config file, see #367 (@sindreij)

- Allow for multiple `--line-range` arguments, see #23

- The `--terminal-width` option can now also accept offsets, see #376

## Changes

  re-enabled by adding `--italic-text=always` to your configuration file.

- The default tab-width has been set to 4.

- Shell completions are currently *not* shipped anymore, see #372 for details.

## Bugfixes

## Other

- `bat` is now available on openSUSE, see #405 (@dmarcoux)

- Added section about the new configuration file in the README (@deg4uss3r)

- Chinese translation of README (@chinanf-boy)

- Re-written tests for `--tabs` (@choznerol)

- Speed up integration tests, see #394

# v0.8.0

## Features

- Support for a configuration file with the following simple format:

  ```bash
  --tabs=4
  --theme="Sublime Snazzy"

  # A line-comment
  --map-syntax .ignore:.gitignore
  --map-syntax PKGBUILD:bash
  --map-syntax Podfile:ruby

  # Flags and options can also be on a single line:
  --wrap=never --paging=never
  ```

  The configuration file path can be accessed via `bat --config-file`. On Linux,
  it is stored in `~/.config/bat/config`.

- Support for the `BAT_OPTS` environment variable with the same format as specified
  above (in a single line). This takes precedence over the configuration file.

  See also #310.

- Support for custom syntax mappings via the `-m`/`--max-syntax` option.

  This allows users to (re)map certain file extensions or file names to an existing syntax:

  ``` bash
  bat --map-syntax .config:json ...
  ```

  The option can be use multiple times. Note that you can easily make these mappings permanent by using bats new configuration file.
