`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

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).

The Gruvbox theme has been updated, see #1291 (@j0hnmeow). Breaking change: users that were previously using gruvbox or gruvbox-white should update and use gruvbox-dark/gruvbox-light instead.

`bat` as a library

The following PrettyPrinter methods have been removed (they were previously deprecated):
- input_stdin_with_name
- input_from_bytes_with_name

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:
```
[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/.

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:
```
--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)

Changes

Change the default configuration directory on macOS to ~/.config/bat, see #442 (@lavifb). If you are on macOS, you need to copy your configuration directory from the previous place (~/Library/Preferences/bat) to the new place (~/.config/bat).
Completely disabled the generation of shell completion files, see #372

see #395 and #381 for more details.

Allow for multiple --line-range arguments, see #23
The --terminal-width option can now also accept offsets, see #376

Changes

Features

Support for a configuration file with the following simple format:

--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:
```
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.
