NAME

     nvim — edit text

SYNOPSIS

     nvim [options] [file ...]
     nvim [options] -
     nvim [options] -t tag
     nvim [options] -q [errorfile]

DESCRIPTION

     nvim is a text editor based on Vim.  Start nvim followed by any number of options and/or
     files:

           nvim [options] [file ...]

     Commands in nvim begin with colon (‘:’).  Type ":help subject" to get help on a specific
     subject.  Use <Tab> and CTRL-D to complete subjects (":help cmdline-completion").

     The "quickref" help section is a condensed reference of editor features:
           :help quickref

     If you are new to Vim/Nvim, start with the 30-minute tutorial:
           :Tutor

     After installing/updating Nvim, it's a good idea to run the self-check:
           :checkhealth

     file ...    File(s) to edit.  Opens one buffer per file.  To switch between buffers, use the
                 :next and :previous commands.

     -           Reads text from standard input until EOF, then opens a buffer with that text.
                 User input is read from standard error, which should be a terminal.

OPTIONS

-t tag Finds tag in the tags file, the associated file becomes the current file and the
associated command is executed. Cursor is positioned at the tag location in the
file. :help tag-commands

-q [errorfile]
QuickFix mode. Display the first error in errorfile. If errorfile is omitted,
the value of the 'errorfile' option is used (defaults to errors.err). Further
errors can be jumped to with the :cnext command. :help quickfix

-- End of options. Remaining arguments are treated as literal file names,
including filenames starting with hyphen (‘-’).

-e Ex mode, reading stdin as Ex commands. :help Ex-mode

-E Ex mode, reading stdin as text. :help Ex-mode

-es Silent (non-interactive) Ex mode, reading stdin as Ex commands. Useful for
scripting because it does NOT start a UI, unlike -e. :help silent-mode

-Es Silent (non-interactive) Ex mode, reading stdin as text. Useful for scripting
because it does NOT start a UI, unlike -E. :help silent-mode

-d Diff mode. Show the difference between two to eight files, similar to sdiff(1).
:help diff

-R Read-only mode. Sets the 'readonly' option. Implies -n. Buffers can still be
edited, but cannot be written to disk if already associated with a file. To
overwrite a file, add an exclamation mark to the relevant Ex command, such as
:w!. :help 'readonly'

-m Resets the 'write' option, to disable file modifications. Writing to a file is
disabled, but buffers can still be modified.

-M Resets the 'write' and 'modifiable' options, to disable file and buffer
modifications.

-b Binary mode. :help edit-binary

-l Lisp mode. Sets the 'lisp' and 'showmatch' options.

-A Arabic mode. Sets the 'arabic' option.

-H Hebrew mode. Sets the 'hkmap' and 'rightleft' options.

-V[N][file]
Verbose mode. Prints debug messages. N is the 'verbose' level, defaults to 10.
If file is specified, append messages to file instead of printing them. :help
'verbose'

-D Debug mode for VimL (Vim script). Started when executing the first command from
a script. :help debug-mode

-n Disable the use of swap files. Sets the 'updatecount' option to 0. Can be
useful for editing files on a slow medium.

-r [file] Recovery mode. If file is omitted then list swap files with recovery
information. Otherwise the swap file file is used to recover a crashed session.
The swap file has the same name as the file it's associated with, but with
‘.swp’ appended. :help recovery

-L [file] Alias for -r.

-u vimrc Use vimrc instead of the default ~/.config/nvim/init.vim. If vimrc is NORC, do
not load any initialization files (except plugins). If vimrc is NONE, loading
plugins is also skipped. :help initialization

-i shada Use shada instead of the default ~/.local/share/nvim/shada/main.shada. If shada
is NONE, do not read or write a ShaDa file. :help shada

--noplugin Skip loading plugins. Implied by -u NONE.

--clean Mimic a fresh install of Nvim. Skip loading non-builtin plugins and shada
(viminfo) file.

-o[N] Open N windows stacked horizontally. If N is omitted, open one window for each
file. If N is less than the number of file arguments, allocate windows for the
first N files and hide the rest.

-O[N] Like -o, but tile windows vertically.

-p[N] Like -o, but for tab pages.

+[linenum] For the first file, position the cursor on line linenum. If linenum is omitted,
position the cursor on the last line of the file. +5 and -c 5 on the command-
line are equivalent to :5 inside nvim.

+/[pattern]
For the first file, position the cursor on the first occurrence of pattern. If
pattern is omitted, the most recent search pattern is used (if any). +/foo and
-c /foo on the command-line are equivalent to /foo and :/foo inside nvim. :help
search-pattern

+command, -c command
Execute command after reading the first file. Up to 10 instances allowed.
"+foo" and -c "foo" are equivalent.

--cmd command
Like -c, but execute command before processing any vimrc. Up to 10 instances of
these can be used independently from instances of -c.

-S [session]
Source session after the first file argument has been read. Equivalent to -c
"source session". session cannot start with a hyphen (‘-’). If session is
omitted then Session.vim is used, if found. :help session-file

-s scriptin
Read normal mode commands from scriptin. The same can be done with the command
:source! scriptin. If the end of the file is reached before nvim exits, further
characters are read from the keyboard.

-w scriptout
Append all typed characters to scriptout. Can be used for creating a script to
be used with -s or :source!.

-W scriptout
Like -w, but truncate scriptout.

--startuptime file
During startup, append timing messages to file. Can be used to diagnose slow
startup times.

--api-info Dump API metadata serialized to msgpack and exit.

--embed Use standard input and standard output as a msgpack-rpc channel. :help --embed

--headless Do not start a UI. When supplied with --embed this implies that the embedding
application does not intend to (immediately) start a UI. Also useful for
"scraping" messages in a pipe. :help --headless

--listen address
Start RPC server on this pipe or TCP socket.

-h, --help Print usage information and exit.

-v, --version
Print version information and exit.

ENVIRONMENT

                 Low-level log file, usually found at ~/.cache/nvim/log.  :help $NVIM_LOG_FILE

                 ~/.config.  :help xdg

                 Like XDG_CONFIG_HOME, but used to store data not generally edited by the user,
