.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

|
|
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.

|
.RS
|
|
.IP "\-\-highlight\-line 40"

|
|
.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'.

|
|
which pager is used, see the '\-\-pager' option. Possible values: *auto*, never, always.
|
|
.HP
|
|
\fB\-\-pager\fR <command>
|
|
.IP
|
|
Determine which pager is used. This option will override the PAGER and BAT_PAGER

|
|
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'.

\fB\-\-theme\fR <theme>
|
|
.IP
|
|

|
|
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

{{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.
