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)

• 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)

Thanks

Special thanks to @rivy for porting our CI/CD workflows to Github Actions. Also, many thanks to @Kienyew and @eth-p for major contributions!

v0.15.4

Bugfixes

• Added missing Solarized themes, see #1027
• Fixed highlighting bug in Haskell source files, see #1026

v0.15.3

Bugfixes

• Cannot run bat with relative paths, see #1022
• bat mishighlights Users that start with digits in SSH config, see #984

New syntaxes

• SML, see #1005 (@kopecs)

Other

• Some syntaxes and themes have been updated to the latest version

v0.15.2

Warning: this release suffers from #1022. bat will panic when called with a relative file path.

Bugfixes

• --map-syntax doesn't work with names provided through --file-name (@eth-p)
• Fix syntax detection for files called 'rails', see #1008
• Fix potential errors with syntax detection for symlinked files, see #1001

Other

• Add padding above headers when not using a grid, see #968 and #981 (@pt2121)
• bat now prints an error if an invalid syntax is specified via -l or --map-syntax, see #1004 (@eth-p)

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

• This release adds 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

  You can use a bash function like

  batdiff() {
      git diff --name-only --diff-filter=d 2>/dev/null | xargs bat --diff
  }

  to essentially get a version of git diff with syntax highlighting (but without being able to see the old version).

  

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, features = ["regex-onig"] }

  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

Thanks

Many thanks to @keith-hall for all the help with various Sublime syntax problems!
