{{PROJECT_EXECUTABLE_UPPERCASE}}(1)

NAME
{{PROJECT_EXECUTABLE}} - a cat(1) clone with syntax highlighting and Git integration.

USAGE

{{PROJECT_EXECUTABLE}} [OPTIONS] [FILE]...

{{PROJECT_EXECUTABLE}} cache [CACHE-OPTIONS] [--build|--clear]

DESCRIPTION
{{PROJECT_EXECUTABLE}} prints the syntax-highlighted content of a collection of FILEs to the terminal. If no FILE is specified, or when FILE is '-', it reads from standard input. {{PROJECT_EXECUTABLE}} supports a large number of programming and markup languages. It also communicates with git(1) to show modifications with respect to the git index. {{PROJECT_EXECUTABLE}} automatically pipes its output through a pager (by default: less). Whenever the output of {{PROJECT_EXECUTABLE}} goes to a non-interactive terminal, i.e. when the output is piped into another process or into a file, {{PROJECT_EXECUTABLE}} will act as a drop-in replacement for cat(1) and fall back to printing the plain file contents.

OPTIONS
General remarks: Command-line options like '-l'/'--language' that take values can be specified as either '--language value', '--language=value', '-l value' or '-lvalue'.

-A, --show-all

    Show non-printable characters like space, tab or newline. Use '--tabs' to control the width of the tab-placeholders.

-p, --plain

    Only show plain style, no decorations. This is an alias for '--style=plain'. When '-p' is used twice ('-pp'), it also disables automatic paging (alias for '--style=plain --pager=never').

-l, --language <language>

    Explicitly set the language for syntax highlighting. The language can be specified as a name (like 'C++' or 'LaTeX') or possible file extension (like 'cpp', 'hpp' or 'md'). Use '--list-languages' to show all supported language names and file extensions.

-H, --highlight-line <N:M>...

    Highlight the specified line ranges with a different background color. For example:

    --highlight-line 40
        highlights line 40

    --highlight-line 30:40
        highlights lines 30 to 40

    --highlight-line :40
        highlights lines 1 to 40

    --highlight-line 40:
        highlights lines 40 to the end of the file

    --highlight-line 30:+10
        highlights lines 30 to 40

--file-name <name>...

    Specify the name to display for a file. Useful when piping data to {{PROJECT_EXECUTABLE}} from STDIN when {{PROJECT_EXECUTABLE}} does not otherwise know the filename. Note that the provided file name is also used for syntax detection.

-d, --diff

    Only show lines that have been added/removed/modified with respect to the Git index. Use '--diff-context=N' to control how much context you want to see.

--diff-context <N>...

    Include N lines of context around added/removed/modified lines when using '--diff'.

--tabs <T>

    Set the tab width to T spaces. Use a width of 0 to pass tabs through directly

--wrap <mode>

    Specify the text-wrapping mode (*auto*, never, character). The '--terminal-width' option can be used in addition to control the output width.

--terminal-width <width>

    Explicitly set the width of the terminal instead of determining it automatically. If prefixed with '+' or '-', the value will be treated as an offset to the actual terminal width. See also: '--wrap'.

-n, --number

    Only show line numbers, no other decorations. This is an alias for '--style=numbers'

--color <when>

    Specify when to use colored output. The automatic mode only enables colors if an interactive terminal is detected. Possible values: *auto*, never, always.

--italic-text <when>

    Specify when to use ANSI sequences for italic text in the output. Possible values: always, *never*.

--decorations <when>

    Specify when to use the decorations that have been specified via '--style'. The automatic mode only enables decorations if an interactive terminal is detected. Possible values: *auto*, never, always.

-f, --force-colorization

    Alias for '--decorations=always --color=always'. This is useful if the output of {{PROJECT_EXECUTABLE}} is piped to another program, but you want to keep the colorization/decorations.

--paging <when>

    Specify when to use the pager. To disable the pager, use '--paging=never' or its alias, -P. To disable the pager permanently, set BAT_PAGER to an empty string. To control which pager is used, see the '--pager' option. Possible values: *auto*, never, always.

--pager <command>

    Determine which pager is used. This option will override the PAGER and BAT_PAGER environment variables. The default pager is 'less'. To control when the pager is used, see the '--paging' option. Example: '--pager "less -RF"'.

-m, --map-syntax <glob-pattern:syntax-name>...

    Map a glob pattern to an existing syntax name. The glob pattern is matched on the full path and the filename. For example, to highlight *.build files with the Python syntax, use -m '*.build:Python'. To highlight files named '.myignore' with the Git Ignore syntax, use -m '.myignore:Git Ignore'. Note that the right-hand side is the *name* of the syntax, not a file extension.

--theme <theme>

    Set the theme for syntax highlighting. Use '--list-themes' to see all available themes. To set a default theme, add the '--theme="..."' option to the configuration file or export the BAT_THEME environment variable (e.g.: export BAT_THEME="...").

--list-themes

    Display a list of supported themes for syntax highlighting.

--style <style-components>

    Configure which elements (line numbers, file headers, grid borders, Git modifications, ..) to display in addition to the file contents. The argument is a comma-separated list of components to display (e.g. 'numbers,changes,grid') or a pre-defined style ('full'). To set a default style, add the '--style=".."' option to the configuration file or export the BAT_STYLE environment variable (e.g.: export BAT_STYLE=".."). Possible values: *full*, auto, plain, changes, header, grid, rule, numbers, snip.

-r, --line-range <N:M>...

    Only print the specified range of lines for each file. For example:

    --line-range 30:40
        prints lines 30 to 40

    --line-range :40
        prints lines 1 to 40

    --line-range 40:
        prints lines 40 to the end of the file

    --line-range 30:+10
        prints lines 30 to 40

-L, --list-languages

    Display a list of supported languages for syntax highlighting.

-u, --unbuffered

    This option exists for POSIX-compliance reasons ('u' is for 'unbuffered'). The output is always unbuffered - this option is simply ignored.

-h, --help

    Print this help message.

-V, --version

    Show version information.

POSITIONAL ARGUMENTS

<FILE>...

    Files to print and concatenate. Use a dash ('-') or no argument at all to read from standard input.

SUBCOMMANDS

cache - Modify the syntax-definition and theme cache.

FILES
{{PROJECT_EXECUTABLE}} can also be customized with a configuration file. The location of the file is dependent on your operating system. To get the default path for your system, call: {{PROJECT_EXECUTABLE}} --config-file Alternatively, you can use the BAT_CONFIG_PATH environment variable to point {{PROJECT_EXECUTABLE}} to a non-default location of the configuration file. To generate a default configuration file, call: {{PROJECT_EXECUTABLE}} --generate-config-file

ADDING CUSTOM LANGUAGES
{{PROJECT_EXECUTABLE}} supports Sublime Text .sublime-syntax language files, and can be customized to add additional languages to your local installation. To do this, add the .sublime-syntax language files to `$({{PROJECT_EXECUTABLE}} --config-dir)/syntaxes` and run `{{PROJECT_EXECUTABLE}} cache --build`. Example:
    mkdir -p "$({{PROJECT_EXECUTABLE}} --config-dir)/syntaxes"
    cd "$({{PROJECT_EXECUTABLE}} --config-dir)/syntaxes" # Put new '.sublime-syntax' language definition files
    # in this folder (or its subdirectories), for example:
    git clone https://github.com/tellnobody1/sublime-purescript-syntax # And then build the cache.
    {{PROJECT_EXECUTABLE}} cache --build
Once the cache is built, the new language will be visible in `{{PROJECT_EXECUTABLE}} --list-languages`.
If you ever want to remove the custom languages, you can clear the cache with `{{PROJECT_EXECUTABLE}} cache --clear`.

ADDING CUSTOM THEMES
Similarly to custom languages, {{PROJECT_EXECUTABLE}} supports Sublime Text .tmTheme themes. These can be installed to `$({{PROJECT_EXECUTABLE}} --config-dir)/themes`, and are added to the cache with `{{PROJECT_EXECUTABLE}} cache --build`.
