.TH {{PROJECT_EXECUTABLE | upcase}} "1"
.SH NAME
{{PROJECT_EXECUTABLE}} \- a cat(1) clone with syntax highlighting and Git integration.
.SH "USAGE"
.IP "{{PROJECT_EXECUTABLE}} [OPTIONS] [FILE]..."
.IP "{{PROJECT_EXECUTABLE}} cache [CACHE-OPTIONS] [--build|--clear]
.SH 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.

.SH "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'.
.HP
\fB\-A\fR, \fB\-\-show\-all\fR
.IP
Show non\-printable characters like space, tab or newline. Use '\-\-tabs' to
control the width of the tab\-placeholders.
.HP
\fB\-p\fR, \fB\-\-plain\fR
.IP
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 \fB\-\-pager\fR=\fI\,never\/\fR').
.HP
\fB\-l\fR, \fB\-\-language\fR <language>
.IP
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.
.HP
\fB\-H\fR, \fB\-\-highlight\-line\fR <N:M>...
.IP
Highlight the specified line ranges with a different background color For example:
.RS
.IP "\-\-highlight\-line 40"
highlights line 40
.IP "\-\-highlight\-line 30:40"
highlights lines 30 to 40
.IP "\-\-highlight\-line :40"
highlights lines 1 to 40
.IP "\-\-highlight\-line 40:"
highlights lines 40 to the end of the file
.RE
.HP
\fB\-\-tabs\fR <T>
.IP
Set the tab width to T spaces. Use a width of 0 to pass tabs through directly
.HP
\fB\-\-wrap\fR <mode>
.IP
Specify the text\-wrapping mode (*auto*, never, character). The '\-\-terminal\-width' option
can be used in addition to control the output width.
.HP
\fB\-\-terminal\-width\fR <width>
.IP
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'.
.HP
\fB\-n\fR, \fB\-\-number\fR
.IP
Only show line numbers, no other decorations. This is an alias for '\-\-style=numbers'
.HP
\fB\-\-color\fR <when>
.IP
Specify when to use colored output. The automatic mode only enables colors if an
interactive terminal is detected. Possible values: *auto*, never, always.
.HP
\fB\-\-italic\-text\fR <when>
.IP
Specify when to use ANSI sequences for italic text in the output. Possible values:
always, *never*.
.HP
\fB\-\-decorations\fR <when>
.IP
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.
.HP
\fB\-\-paging\fR <when>
.IP
Specify when to use the pager. To control which pager is used, set the PAGER or
BAT_PAGER environment variables (the latter takes precedence) or use the '\-\-pager'
option. To disable the pager permanently, set BAT_PAGER to an empty string or set
\&'\-\-paging=never' in the configuration file. Possible values: *auto*, never, always.
.HP
\fB\-\-pager\fR <command>
.IP
Determine which pager is used. This option will overwrite the PAGER and BAT_PAGER
environment variables. The default pager is 'less'. To disable the pager completely, use
the '\-\-paging' option. Example: '\-\-pager "less \fB\-RF\fR"'.
.HP
\fB\-m\fR, \fB\-\-map\-syntax\fR <from:to>...
.IP
Map a file extension or file name to an existing syntax (specified by a file extension
or file name). For example, to highlight *.build files with the Python syntax, use '\-m
build:py'. To highlight files named '.myignore' with the Git Ignore syntax, use '\-m
\&.myignore:gitignore'.
.HP
\fB\-\-theme\fR <theme>
.IP
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="...").
.HP
\fB\-\-list\-themes\fR
.IP
Display a list of supported themes for syntax highlighting.
.HP
\fB\-\-style\fR <style\-components>
.IP
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: *auto*, full, plain, changes, header, grid, numbers, snip.
.HP
\fB\-r\fR, \fB\-\-line\-range\fR <N:M>...
.IP
Only print the specified range of lines for each file. For example:
.RS
.IP "\-\-line\-range 30:40"
prints lines 30 to 40
.IP "\-\-line\-range :40"
prints lines 1 to 40
.IP "\-\-line\-range 40:"
prints lines 40 to the end of the file
.RE
.HP
\fB\-L\fR, \fB\-\-list\-languages\fR
.IP
Display a list of supported languages for syntax highlighting.
.HP
\fB\-u\fR, \fB\-\-unbuffered\fR
.IP
This option exists for POSIX\-compliance reasons ('u' is for 'unbuffered'). The output is
always unbuffered \- this option is simply ignored.
.HP
\fB\-h\fR, \fB\-\-help\fR

.HP
\fB\-V\fR, \fB\-\-version\fR
.IP

.IP
Files to print and concatenate. Use a dash ('\-') or no argument at all to read from
standard input.
.SH "SUBCOMMANDS"
.HP
\fBcache\fR - Modify the syntax\-definition and theme cache.
.SH "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:

\fB{{PROJECT_EXECUTABLE}} --config-file\fR

Alternatively, you can use the BAT_CONFIG_PATH environment variable to point bat to a non-default
location of the configuration file.
