bat as a library

v0.21.0

Features

  • Correctly render tab stops in --show-all, see #2038 (@Synthetica9)
  • Add a --style=default option and make it the default. It is less verbose than full, see #2061 (@IsaacHorvath)

v0.19.0

Performance

  • Reduce startup time in loop-through mode (e.g. when redirecting output) by 90%. See #1747 (@Enselic)
  • Load themes lazily to make bat start 25% faster when disregarding syntax load time. See #1969 (@Enselic)
  • Python syntax highlighting no longer suffers from abysmal performance in specific scenarios. See #1688 (@keith-hall)
  • Fix for poor performance when ANSI escape sequences are piped to bat, see #1596 (@eth-p)
  • Fix for incorrect handling of ANSI escape sequences when using --wrap=never, see #1596 (@eth-p)
  • Load custom assets as fast as integrated assets, see #1753 (@Enselic)

  • Include git hash in bat -V and bat --version output if present. See #1921 (@Enselic)

Bugfixes

  • First line not shown in diff context. See #1891 (@divagant-martian)
  • Do not ignore syntaxes that handle file names with a *.conf extension. See #1703 (@cbolgiano)

Other

  • Add PowerShell completion, see #1826 (@rashil2000)
  • Minimum supported Rust version (MSRV) bumped to 1.51, see #1994 (@mdibaiee)

Syntaxes

  • Groff, see #1685 (@scop)
  • HTTP Requests and Responses, see #1748 (@keith-hall)
  • LLVM, see #1777 (@ioncodes)
  • Highlight for vimrc and gvimrc files, see #1763 (@SuperSandro2000)
  • Syslog highlighting improvements, see #1793 (@scop)
  • Added support for slim syntax, see #1693 (@mfinelli)

  • TypeScript syntax updated, see #1834 (@Enselic)

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)
  • Fix Clippy lints, see #1661 (@mohamed-abdelnour)

New themes

  • Dark+ VS Code theme, see #1588 and #1598 (@PatriotRossii)

v0.18.0

Features

  • Use a pager when bat --list-languages is called, see #1394 (@stku1985)

Bugfixes

  • If the last line doesn't end with a newline character, don't add it if --style=plain, see #1438 (@Enselic)

  • Print an 'Invalid syntax theme settings' error message if a custom theme is broken, see #614 (@Enselic)
  • 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)
  • 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

  • Highlight *.pac (Proxy auto-config) files as JavaScript, see #1515 (@sharkdp)

New themes

  • ansi replaces ansi-dark and ansi-light, see #1104 and #1412 (@mk12). Breaking change: users that were previously using one of the ansi-* themes should switch to ansi.
  • 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

bat as a library

  • PrettyPrinter::vcs_modification_markers has been marked deprecated when building without the git feature, see #997 and #1020 (@eth-p, @sharkdp)

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:

    [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)
  • 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)
  • Allow for non-unicode filenames, see #225 (@sharkdp)
  • Empty file without header produces incomplete grid, see #798 (@eth-p)

--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.
