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

Features

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

Bugfixes

• Fix for a security vulnerability on Windows (CVE-2021-36753). 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

• 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.
