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)

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).

• If plain mode is set and wrap is not explicitly opted in, long lines will no be truncated, see #1426
• If PAGER (but not BAT_PAGER or --pager) is more or most, silently use less instead to ensure support for colors, see #1063 (@Enselic)

• 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.

• 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)

• Completely disabled the generation of shell completion files, see #372
• Properly set arguments to less if PAGER environment variable contains something like less -F (which is missing the -R option), see #430 (@majecty)

  see #395 and #381 for more details.

• Added --pager option (to configure the pager from the configuration file), see #362 (@majecty)

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

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

  --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.
