Normally you don't have to set or reset this option. When 'binary' is off the value is not used when writing the file. But you can change it if neovim binary option want to. When 'binary' is off and 'fixeol' is on the value is not used when writing neovim binary option file.

Turn this option off if neovim binary option want to preserve the situation from the original file. When the 'binary' option is set the value of this option doesn't matter.

Last change: Dec Last change: Oct VIM REFERENCE MANUAL by Bram Moolenaar. local to buffer. When writing a file and this option is off and the 'binary' neovim binary option.

option is automatically set when starting to edit a new file, unless. which case it is reset. Normally you don't have to set or reset this. Initialization initialization startup. At startup, Nvim checks environment variables and files and sets values accordingly, proceeding as follows:.

Set the 'shell' option SHELL COMSPEC The environment variable SHELL, if it exists, is used to set the 'shell' option. On Win32, the COMSPEC variable is used if SHELL is not set. Process the arguments The options and file names from the command that start Vim are inspected. Buffers are created for all files but not loaded yet. The -V argument can be used to display or log what happens next, useful for debugging the initializations. Start a server unless --listen was given and set v:servername.

Wait for UI to connect. Nvim started with --embed waits for the UI to connect before proceeding to load user configuration. Setup default-mappings and default-autocmds. Create popup-menu. Enable filetype and indent plugins.

This does the same as the command: :runtime! vim indent. Load user config execute Ex commands from files, environment, …. config init. vim init. lua vimrc exrc A file containing initialization commands is generically called a "vimrc" or config file. It can be either Vimscript "init. vim" or Lua "init. lua" , but not both. E See also vimrc-intro and base-directories. vim or init. If Nvim was started with "-u {file} " then {file} is used as the config and all initializations until 5.

are skipped. If Nvim was started with -es all initializations until 5. system-vimrc sysinit. vim a. The system vimrc file is read for initializations. Otherwise the system vimrc file is used. The path of this file is given by the :version command. If the 'exrc' option is on which is NOT the default , the current directory is searched for two files. The first that exists is used, the others are ignored. The file ". Enable filetype detection. Skipped if ":filetype off" was called or if the "-u NONE" command line argument was given.

Enable syntax highlighting. Skipped if ":syntax off" was called or if the "-u NONE" command line argument was given. Load the plugin scripts. load-plugins This does the same as the command: :runtime! vim :runtime! The result is that all directories in 'runtimepath' will be searched for the "plugin" sub-directory and all files ending in ".

vim" or ". lua" will be sourced in alphabetical order per directory , also in subdirectories. lua" files. However, directories in 'runtimepath' ending in "after" are skipped here and only loaded after packages, see below. Loading plugins won't be done when: The 'loadplugins' option was reset in a vimrc file. The --noplugin command line argument is used.

The --clean command line argument is used. The "-u NONE" command line argument is used -u. Note that using "-c ' set noloadplugins'" doesn't work, because the commands from the command line have not been executed yet. You can use "--cmd ' set noloadplugins'" or "--cmd ' set loadplugins'" --cmd.

Packages are loaded. These are plugins, as above, but found in the "start" directory of each entry in 'packpath'. Every plugin directory found is added in 'runtimepath' and then the plugins are sourced. See packages. The plugins scripts are loaded, as above, but now only the directories ending in "after" are used. Note that 'runtimepath' will have changed if packages have been found, but that should not add a directory ending in "after". Set 'shellpipe' and 'shellredir' The 'shellpipe' and 'shellredir' options are set according to the value of the 'shell' option, unless they have been set before.

This means that Nvim will figure out the values of 'shellpipe' and 'shellredir' for you, unless you have set them yourself. Set 'updatecount' to zero, if "-n" command argument used. Set binary options if the -b flag was given. Read the quickfix file if the -q flag was given, or exit on failure. Open all windows When the -o flag was given, windows will be opened but not displayed yet. When the -p flag was given, tab pages will be created but not displayed yet.

When switching screens, it happens now. Redrawing starts. If the -q flag was given, the first error is jumped to. Buffers for all windows will be loaded, without triggering BufAdd autocommands. Execute startup commands If a -t flag was given, the tag is jumped to. The VimEnter autocommands are executed. Saving the current state of Vim to a file. Whenever you have changed values of options or when you have created a mapping, then you may want to save them in a vimrc file for later use.

See save-settings about saving the current state of settings to a file. If you have 'shada' enabled, the loading of the ShaDa file may take a while. You can find out if this is the problem by disabling ShaDa for a moment use the Vim argument "-i NONE", -i.

To find the cause of a problem in your config, you must "bisect" it: 1. Remove or disable half of your config.

Restart Nvim. If the problem still occurs, goto 1. If the problem is gone, restore half of the removed lines. Continue narrowing your config in this way, until you find the setting or plugin causing the issue. This depends on the system, see startup.

File name "help. txt", etc. is removed. Trailing directory names are removed, in this order: "doc", "runtime". Path derived from the location of the nvim executable. Compile-time defined installation directory see output of ":version". This is for backwards compatibility with older Vim versions. txt" removed from the end. Works in Normal and in Visual mode. In Insert and Command-line mode, the CTRL-Z is inserted as a normal character. In Visual mode Nvim goes back to Normal mode.

Triggers VimSuspend before suspending and VimResume when resumed. Exiting exiting. There are several ways to exit Vim: Close the last window with :quit. Only when there are no changes.

Close the last window with :quit! Also when there are changes. Close all windows with :qall. Close all windows with :qall! When using :cquit or when there was an error message Vim exits with exit code 1. Errors can be avoided by using :silent! or with :catch. Saving settings save-settings.

Mostly you will edit your vimrc files manually. This gives you the greatest flexibility. There are a few commands to generate a vimrc file automatically. exrc" in the current directory , unless it already exists. exrc" in the current directory. nvimrc" in the current directory. The ":version" command is also written to the file. These commands will write ":map" and ":set" commands to a file, in such a way that when these commands are executed, the current key mappings and options will be set to the same values.

The options 'columns' , 'endofline' , 'fileformat' , 'lines' , 'modified' , and 'scroll' are not included, because these are terminal or file dependent.

Note that the options 'binary' , 'paste' and 'readonly' are included, this might not always be what you want. When special keys are used in mappings, The 'cpoptions' option will be temporarily set to its Vim default, to avoid the mappings to be misinterpreted.

This makes the file incompatible with Vi, but makes sure it can be used with different terminals. A common method is to use a default config file, make some modifications with ":map" and ":set" commands and write the modified file. Cprogs", change the settings and then save them in the current directory with ":mkvimrc! vimrc-option-example If you only want to add a single option setting to your vimrc, you can use these steps: 1.

Edit your vimrc file with Vim. Play with the option until it's right. Views and Sessions views-sessions. This is introduced in sections View view-file A View is a collection of settings that apply to one window. You can save a View and when you restore it later, the text is displayed in the same way.

The options and mappings in this window will also be restored, so that you can continue editing like when the View was saved. Session session-file A Session keeps the Views for all windows, plus the global settings. You can save a Session and when you restore it later the window layout looks the same.

You can use a Session to quickly switch between different projects, automatically loading the files you were last working on in that project. Views and Sessions are a nice addition to ShaDa files, which are used to remember information for all Views and Sessions together shada-file. You can quickly start editing with a previously saved View or Session with the -S argument: vim -S Session. When [!

When [file] is omitted "Session. vim" is used. The output of ":mksession" is like ":mkvimrc", but additional commands are added to the file. Which ones depends on the 'sessionoptions' option. The resulting file, when executed with a ":source" command: 1. Restores global mappings and options, if 'sessionoptions' contains "options".

Script-local mappings will not be written. Restores global variables that start with an uppercase letter and contain at least one lowercase letter, if 'sessionoptions' contains "globals". Closes all windows in the current tab page, except the current one; closes all tab pages except the current one this results in currently loaded buffers to be unloaded, some may become hidden if 'hidden' is set or otherwise specified ; wipes out the current buffer, if it is empty and unnamed.

Restores the current directory if 'sessionoptions' contains "curdir", or sets the current directory to where the Session file is if 'sessionoptions' contains "sesdir". Restores GUI Vim window position, if 'sessionoptions' contains "winpos". Restores screen size, if 'sessionoptions' contains "resize".

Reloads the buffer list, with the last cursor positions. If 'sessionoptions' contains "buffers" then all buffers are restored, including hidden and unloaded buffers. Otherwise only buffers in windows are restored. Restores all windows with the same layout. If 'sessionoptions' contains "help", help windows are restored. If 'sessionoptions' contains "blank", windows editing a buffer without a name will be restored.

Otherwise, the windows are just given sensible sizes. Restores the Views for all the windows, as with :mkview. But 'sessionoptions' is used instead of 'viewoptions'. If a file exists with the same name as the Session file, but ending in "x. vim" for eXtra , executes that as well.

You can usex. vim files to specify additional settings and actions associated with a given Session, such as creating menu items in the GUI version. A session includes all tab pages, unless "tabpages" was removed from 'sessionoptions'. SessionLoad-variable While the session file is loading the SessionLoad global variable is set to 1. Plugins can use this to postpone some work until the SessionLoadPost event is triggered.

See spell. To include a comma in a file name precede it with a backslash. Spaces after a comma are ignored, otherwise spaces are included in the file name. See option-backslash about using backslashes. This has nothing to do with the Dictionary variable type. Where to find a list of words? Backticks cannot be used in this option for security reasons.

See diff-mode. See diff-diffexpr. It can consist of the following items. All are optional. Items must be separated by a comma. filler Show filler lines, to keep the text synchronized with a window that has inserted lines at the same position.

Mostly useful when windows are side-by-side and 'scrollbind' is set. context:{n} Use a context of {n} lines between a change and a fold that contains unchanged lines. When omitted a context of six lines is used. When using zero the context is actually one, since folds require a line in between, also for a deleted line. See fold-diff. iblank Ignore changes where lines are all blank.

Adds the "-B" flag to the "diff" command if 'diffexpr' is empty. Check the documentation of the "diff" command for what this does exactly. NOTE: the diff windows will get out of sync, because no differences between blank lines are taken into account. icase Ignore changes in case of text. Adds the "-i" flag to the "diff" command if 'diffexpr' is empty. iwhite Ignore changes in amount of white space. Adds the "-b" flag to the "diff" command if 'diffexpr' is empty.

It should ignore adding trailing white space, but not leading white space. iwhiteall Ignore all white space changes. Adds the "-w" flag to the "diff" command if 'diffexpr' is empty. iwhiteeol Ignore white space changes at end of line. Adds the "-Z" flag to the "diff" command if 'diffexpr' is empty.

horizontal Start diff mode with horizontal splits unless explicitly specified otherwise. vertical Start diff mode with vertical splits unless explicitly specified otherwise. closeoff When a window is closed where 'diff' is set and there is only one window remaining in the same tab page with 'diff' set, execute :diffoff in that window.

This undoes a :diffsplit command. hiddenoff Do not use diff mode for a buffer when it becomes hidden. foldcolumn:{n} Set the 'foldcolumn' option to {n} when starting diff mode. Without this 2 is used. followwrap Follow the 'wrap' option and leave as it is. internal Use the internal diff library.

This is ignored when 'diffexpr' is set. E When running out of memory when writing a buffer this item will be ignored for diffs involving that buffer. Set the 'verbose' option to see when this happens. indent-heuristic Use the indent heuristic for the internal diff library.

linematch:{n} Enable a second stage diff on each generated hunk in order to align lines. When the total number of lines in a hunk exceeds {n} , the second stage diff will not be performed as very large hunks can cause noticeable lag.

A recommended setting is "linematch", as this will enable alignment for a 2 buffer diff with hunks of up to 30 lines each, or a 3 buffer diff with hunks of up to 20 lines each.

algorithm:{text} Use the specified diff algorithm with the internal diff engine. Currently supported algorithms are: myers the default algorithm minimal spend extra time to generate the smallest possible diff patience patience diff algorithm histogram histogram diff algorithm. See digraphs. Possible items: The swap file will be created in the first directory where this is possible.

If it is not possible in any directory, but last directory listed in the option does not exist, it is created. Empty means that no swap file will be used recovery is impossible! and no E error will be given. On Unix, a dot is prepended to the file name, so it doesn't show in a directory listing. On MS-Windows the "hidden" attribute is set and a dot prepended if possible.

This will ensure file name uniqueness in the preserve directory. Using ". This means that editing the same file twice will result in a warning. But others on the computer may be able to see the files, and it can contain a lot of files, your swap files get lost in the crowd. That is why a "tmp" directory in your home directory is tried first.

This is a comma-separated list of flags: lastline When included, as much as possible of the last line in a window will be displayed. truncate Like "lastline", but " " is displayed in the first column of the last screen line. Overrules "lastline". msgsep Obsolete flag. Allowed but takes no effect. When neither "lastline" nor "truncate" is included, a last line that doesn't fit is replaced with " " lines.

The " " character can be changed by setting the "lastline" item in 'fillchars'. The character is highlighted with hl-NonText. This excludes "text emoji" characters, which are normally displayed as single width. Unfortunately there is no good specification for this and it has been determined on trial-and-error basis. Use the setcellwidths function to change the behavior. Always UTF See 'fileencoding' to control file-content encoding. Normally only happens when 'fileformat' is "dos".

When writing a file and this option is off and the 'binary' option is on, or 'fixeol' option is off, no CTRL-Z will be written at the end of the file. See eol-and-eof for example settings. Normally you don't have to set or reset this option. When 'binary' is off and 'fixeol' is on the value is not used when writing the file. But you can change it if you want to. This also happens the moment the option is switched on.

When off, splitting a window will reduce the size of the current window and leave the other windows the same. When closing a window the extra lines are given to the window next to it depending on 'splitbelow' and 'splitright'. When mixing vertically and horizontally split windows, a minimal size is computed and some windows may be larger if there is room.

The 'eadirection' option tells in which direction the size is affected. Changing the height and width of a window can be avoided by setting 'winfixheight' and 'winfixwidth' , respectively. If a window size is specified when creating a new window sizes are currently not equalized it's complicated, but may be implemented in the future. When this option is empty the internal formatting functions are used; either 'lisp' , 'cindent' or 'indentexpr'.

See option-backslash about including spaces and backslashes. This only makes a difference for error messages, the bell will be used always for a lot of errors without a message e. See 'visualbell' to make the bell behave like a screen flash or do nothing.

See 'belloff' to finetune when to ring the bell. err" global Name of the errorfile for the QuickFix mode see :cf. When the "-q" command-line argument is used, 'errorfile' is set to the following argument.

See -q. NOT used for the ":make" command. See 'makeef' for that. When set to "all" or when "all" is one of the items, all autocommand events are ignored, autocommands will not be executed. Otherwise this is a comma-separated list of event names. See also :retab and ins-expandtab. This option is reset when the 'paste' option is set and restored when the 'paste' option is reset. nvimrc and.

exrc files in the current directory. The file is only sourced if the user indicates the file is trusted. If it is, the SHA hash of the file contents and the full path of the file are persisted to a trust database. The user is only prompted again if the file contents change. See vim. Conversion is done with iconv or as specified with 'charconvert'. When 'fileencoding' is not UTF-8, conversion will be done when writing the file.

For reading see below. When 'fileencoding' is empty, the file will be saved with UTF-8 encoding no conversion when reading or writing a file. WARNING: Conversion to a non-Unicode encoding can cause loss of information! See encoding-names for the possible values. Additionally, values may be specified that can be handled by the converter, see mbyte-conversion. When reading a file 'fileencoding' will be set from 'fileencodings'.

One exception: when 'fileencodings' is empty the value of 'fileencoding' is used. For a new file the global value of 'fileencoding' is used. Prepending "8bit-" and "2byte-" has no meaning here, they are ignored. When the option is set, the value is converted to lowercase. Thus you can set it with uppercase values too. If a name is recognized from the list at encoding-names , it is replaced by the standard name.

For example "ISO" becomes "iso". When this option is set, after starting to edit a file, the 'modified' option is set, because the file would be different when written. Keep in mind that changing 'fenc' from a modeline happens AFTER the text has been read, thus it applies to when the file will be written. If you do set 'fenc' in a modeline, you might want to set 'nomodified' to avoid not being able to ":q". This option cannot be changed when 'modifiable' is off. When a file is read, Vim tries to use the first mentioned character encoding.

If an error is detected, the next one in the list is tried. When an encoding is found that works, 'fileencoding' is set to it. If all fail, 'fileencoding' is set to an empty string, which means that UTF-8 is used. WARNING: Conversion can cause loss of information! For an empty file or a file with only ASCII characters most encodings will work and the first entry of 'fileencodings' will be used except "ucs-bom", which requires the BOM to be present.

If you prefer another encoding use an BufReadPost autocommand event to test if your preferred encoding is to be used. This sets 'fileencoding' to "isojp" if the file does not contain non-blank characters. Note that 'fileencodings' is not used for a new file, the global value of 'fileencoding' is used instead. This means that a non-existing file may get a different encoding than an empty file.

The special value "ucs-bom" can be used to check for a Unicode BOM Byte Order Mark at the start of the file. It must not be preceded by "utf-8" or another Unicode encoding for this to work properly. An entry for an 8-bit encoding e. The special value "default" can be used for the encoding from the environment. It is useful when your environment uses a non-latin1 encoding, such as Russian.

When a file contains an illegal UTF-8 byte sequence it won't be recognized as "utf-8". You can use the 8g8 command to find the illegal byte sequence. WRONG VALUES: WHAT'S WRONG: latin1,utf-8 "latin1" will always be used utf-8,ucs-bom,latin1 BOM won't be recognized in an utf-8 file cp,latin1 "cp" will always be used If 'fileencodings' is empty, 'fileencoding' is not modified.

See 'fileencoding' for the possible values. Setting this option does not have an effect until the next time a file is read. See file-formats and file-read. For the character encoding of the file see 'fileencoding'. This option is set automatically when starting to edit a file and 'fileformats' is not empty and 'binary' is off.

It is not set automatically. When set to one name, that format will be used whenever a new buffer is opened. The 'fileformats' name will be used when a file is read into an existing buffer, no matter what 'fileformat' for that buffer is set to.

If 'fileformat' is still not set, the first name from 'fileformats' is used. When reading a file into an existing buffer, the same is done, but this happens like 'fileformat' has been set appropriately for that file only, the option is not changed. When 'binary' is set, the value of 'fileformats' is not used. When Vim starts up with an empty buffer the first item is used. You can overrule this by setting 'fileformat' in your. Dos format will be used. When 'fileformats' is set to one or more names, automatic detection is done.

Also see file-formats. See 'wildignorecase' for only ignoring case when doing completion. All autocommands that match with the value of this option will be executed.

Thus the value of 'filetype' is used in place of the file name. Otherwise this option does not always reflect the current file type. This option is normally set when the file type is detected. To enable this use the ":filetype on" command.

FileType filetypes When a dot appears in the value then this separates two filetype names. This will use the "c" filetype first, then the "doxygen" filetype. This works both for filetype plugins and for syntax files. More than one dot may appear.

This option is not copied to another buffer, independent of the 's' or 'S' flag in 'cpoptions'. It is a comma-separated list of items. Each item has a name, a colon and the value of that item:. Any one that is omitted will fall back to the default. Note that "horiz", "horizup", "horizdown", "vertleft", "vertright" and "verthoriz" are only used when 'laststatus' is 3, since only vertical window separators are used otherwise.

If 'ambiwidth' is "double" then "horiz", "horizup", "horizdown", "vert", "vertleft", "vertright", "verthoriz", "foldsep" and "fold" default to single-byte alternatives. This is similar to the default, except that these characters will also be used when there is highlighting. For the "stl", "stlnc", "foldopen", "foldclose" and "foldsep" items single-byte and multibyte characters are supported.

But double-width characters are not supported. The highlighting used for these items: item highlight group. Turn this option off if you want to preserve the situation from the original file.

When the 'binary' option is set the value of this option doesn't matter. Useful if you want folds to automatically close when moving out of them. Valid values are: "auto": resize to the minimum amount of folds to display. This option can be used to quickly switch between showing all text unfolded and viewing the text with folds including manually opened or closed folds. It can be toggled with the zi command. The 'foldcolumn' will remain blank when 'foldenable' is off.

This option is set by commands that create a new fold or close a fold. See folding. It is evaluated for each line to obtain its fold level. See fold-expr. The expression will be evaluated in the sandbox if set from a modeline, see sandbox-option. This option can't be set from a modeline when the 'diff' option is on or the 'modelineexpr' option is off.

It is not allowed to change text or jump to another window while evaluating 'foldexpr' textlock. Lines starting with characters in 'foldignore' will get their fold level from surrounding lines. White space is skipped before checking for this character. The default " " works well for C programs. See fold-indent. Setting this option to zero will close all folds. Higher numbers will close fewer folds.

This option is set by commands like zm , zM and zR. See fold-foldlevel. Useful to always start editing with all folds closed value zero , some folds closed one or no folds closed This is done before reading any modeline, thus a setting in a modeline overrules this option.

Starting to edit a file for diff-mode also ignores this option and closes all folds. It is also done before BufReadPre autocommands, to allow an autocmd to overrule the 'foldlevel' value for specific files. When the value is negative, it is not used. There must be one comma, which separates the start and end marker.

The marker is a literal string a regular expression would be too slow. See fold-marker. Possible values: fold-manual manual Folds are created manually. fold-indent indent Lines with equal indent form a fold. fold-expr expr 'foldexpr' gives the fold level of a line. fold-marker marker Markers are used to specify folds. fold-syntax syntax Syntax highlighting items specify folds. fold-diff diff Fold text that is not changed. Also for manually closed folds. With the default value of one a fold can only be closed if it takes up two or more screen lines.

Set to zero to be able to close folds of just one screen line. Note that this only has an effect on what is displayed. After using "zc" to close a fold, which is displayed open because it's smaller than 'foldminlines' , a following "zc" may close a containing fold. This avoids that too many folds will be created. Using more than 20 doesn't work, because the internal limit is NOTE: When the command is part of a mapping this option is not used.

Add the zv command to the mapping to get the same effect. rationale: the mapping may want to control opening folds itself.

See fold-foldtext. This option cannot be set in a modeline when 'modelineexpr' is off. It is not allowed to change text or jump to another window while evaluating 'foldtext' textlock. When this option is empty 'formatprg' is used. The v:lnum variable holds the first line to be formatted. The v:count variable holds the number of lines to be formatted. The v:char variable holds the character that is going to be inserted if the expression is being evaluated due to automatic formatting.

This can be empty. Don't insert it yet! vim file in 'runtimepath'. The expression is also evaluated when 'textwidth' is set and adding text beyond that limit. This happens under the same conditions as when internal formatting is used. Make sure the cursor is kept in the same spot relative to the text then! The mode function will return "i" or "R" in this situation. When the expression evaluates to non-zero Vim will fall back to using the internal format mechanism.

The expression will be evaluated in the sandbox when set from a modeline, see sandbox-option. That stops the option from working, since changing the buffer text is not allowed. NOTE: This option is set to "" when 'compatible' is set. This is used for the "n" flag in 'formatoptions'. The pattern must match exactly the text that will be the indent for the line below it. There must be a character following the pattern, when it matches the whole line it is handled like there is no match.

The default recognizes a number, followed by an optional punctuation character and white space. See fo-table. When the 'paste' option is on, no formatting is done like 'formatoptions' is empty. Commas can be inserted for readability. The program must take the input on stdin and produce the output on stdout. The Unix program "fmt" is such a program. If the 'formatexpr' option is not empty it will be used instead. Otherwise, if 'formatprg' option is an empty string, the internal format function will be used C-indenting.

This flushes the file to disk, ensuring that it is safely written. Slow on some systems: writing buffers, quitting Nvim, and other operations may sometimes take a few seconds. Files are ALWAYS flushed 'fsync' is ignored when: CursorHold event is triggered. This means that all matches in a line are substituted instead of one. When a 'g' flag is given to a ":substitute" command, this will toggle the substitution of all or one match. See complex-change. command 'gdefault' on 'gdefault' off.

This is a scanf-like string that uses the same format as the 'errorformat' option: see errorformat. Special value: When 'grepprg' is set to "internal" the :grep command works like :vimgrep , :lgrep like :lvimgrep , :grepadd like :vimgrepadd and :lgrepadd like :lvimgrepadd. Works in the GUI and many terminals. See tui-cursor-shape. The option is a comma-separated list of parts.

Each part consists of a mode-list and an argument-list: mode-list:argument-list,mode-list:argument-list,.. The mode-list is a dash separated list of these modes: n Normal mode v Visual mode ve Visual mode with 'selection' "exclusive" same as 'v', if not specified o Operator-pending mode i Insert mode r Replace mode c Command-line Normal append mode ci Command-line Insert mode cr Command-line Replace mode sm showmatch in Insert mode a all modes The argument-list is a dash separated list of these arguments: hor{N} horizontal bar, {N} percent of the character height ver{N} vertical bar, {N} percent of the character width block block cursor, fills the whole character Only one of the above three should be present.

Default is "block" for each mode. blinkwait{N} cursor-blinking blinkon{N} blinkoff{N} blink times for cursor: blinkwait is the delay before the cursor starts blinking, blinkon is the time that the cursor is shown and blinkoff is the time that the cursor is not shown.

Times are in msec. When one of the numbers is zero, there is no blinking. Default is "blinkon0" for each mode. In the TUI :. ctermfg and guifg are ignored. Examples of parts: n-c-v:block-nCursor In Normal, Command-line and Visual mode, use a block cursor with colors from the "nCursor" highlight group n-v-c-sm:block,i-ci-ve:verCursor,r-cr-o:hor20 In Normal et al. modes, use a block cursor with the default colors defined by the host terminal. In Insert-likes modes, use a vertical bar cursor with colors from "Cursor" highlight group.

In Replace-likes modes, use a underline cursor with default colors. Blink a bit faster. The 'a' mode is different. It will set the given argument-list for all modes. It does not reset anything to defaults. This can be used to do a common setting for all modes. For example, to switch off blinking: "a:blinkon0". In its simplest form the value is just one font name. When the font cannot be found you will get an error message.

To try other font names a list can be specified, font names separated with commas. The first valid font is used. Spaces after a comma are ignored. To include a comma in a font name precede it with a backslash. Setting an option requires an extra backslash before a space and a backslash. See also option-backslash.

will make Vim try to use the font "Screen15" first, and if it fails it will try to use "7x13" and then "font,with,commas" instead. If none of the fonts can be loaded, Vim will keep the current setting. If an empty font list is given, Vim will try using other resource settings for X, it will use the Vim. font resource , and finally it will try some builtin default which should always be there "7x13" in the case of X. The font names given should be "normal" fonts.

Vim will try to find the related bold and italic fonts. E Note that the fonts must be mono-spaced all characters have the same width. To preview a font on X11, you might be able to use the "xfontsel" program. The "xlsfonts" program gives a list of all available fonts. For the Win32 GUI E E takes these options in the font name: hXX - height is XX points, can be floating-point wXX - width is XX points, can be floating-point b - bold i - italic u - underline s - strikeout cXX - character set XX.

Normally you would use "cDEFAULT". Use a ':' to separate the options. The first font that can be loaded is used. Note: The size of these fonts must be exactly twice as wide as the one specified with 'guifont' and the same height. When 'guifont' has a valid font and 'guifontwide' is empty Vim will attempt to set 'guifontwide' to a matching double-width font.

It is a sequence of letters which describes what components and options of the GUI should be used. This means that the Visually highlighted text is available for pasting into other applications as well as into Vim itself. Thus the selection is still available for pasting into other applications after the VISUAL mode has ended. The same applies to the modeless selection. Like 'a', but only applies to the modeless selection.

When 'e' is missing a non-GUI tab pages line may be used. vim" is not sourced. Note that this flag must be added in the vimrc file, before switching on syntax or filetype recognition when the gvimrc file is sourced the system menu has already been loaded; the :syntax on and :filetype on commands load the menu too. If 'g' is not included inactive menu items are not shown at all. Currently only in Win32 GUI. Its size depends on the longest visible line, or on the cursor line if the 'h' flag is included.

gui-horiz-scroll 'go-h' 'h' Limit horizontal scrollbar size to the length of the cursor line. Reduces computations. And yes, you may even have scrollbars on the left AND the right if you really want to See gui-scrollbars for more information. When not included, a horizontal layout is preferred, but when it doesn't fit a vertical layout is used anyway. Not supported in GTK 3. This is required for some window managers. If the cursor is not blinking or hollow at the right moment, try adding this flag.

This must be done before starting the GUI. Set it in your gvimrc. Adding or removing it after the GUI has started has no effect. Instead, the behavior is similar to when the window is maximized and will adjust 'lines' and 'columns' to fit to the window. Without the 'k' flag Vim will try to keep 'lines' and 'columns' the same when adding and removing GUI components.

Nvim :help pages, generated from source using the tree-sitter-vimdoc parser. VIM USER MANUAL - by Bram Moolenaar. This chapter is about editing files that are not ordinary files.

With Vim you can edit files that are compressed. Some files need to be accessed over the internet. With some restrictions, binary files can be edited as well. Back in the early days, the old Teletype machines used two characters to start a new line. When computers came out, storage was expensive. Some people decided that they did not need two characters for end-of-line.

This means that if you try to move a file from one system to another, you have line-break problems. The Vim editor automatically recognizes the different file formats and handles things properly behind your back. The option 'fileformats' contains the various formats that will be tried when a new file is edited. You don't see anything if you edit a native file format.

Thus editing a Unix file on Unix won't result in a remark. But when you edit a dos file, Vim will notify you of this:. For a Mac file you would see "[mac]". The detected file format is stored in the 'fileformat' option.

To see which format you have, execute the following command: :set fileformat? The three names that Vim uses are:. USING THE MAC FORMAT. Incidentally, this happens quite often in Vi and Vim scripts.

Therefore, Vim assumes that on Unix you probably won't edit a Mac file, and doesn't check for this type of file. Watch out for situations where Vim guesses wrong.

The automatic detection avoids this. Suppose you do want to edit the file that way? You can use the 'fileformat' option to convert from one file format to another.

Suppose, for example, that you have an MS-DOS file named README. TXT that you want to convert to Unix format. Start by editing the MS-DOS format file: vim README. TXT Vim will recognize this as a dos format file. Someone sends you an e-mail message, which refers to a file by its URL.

For example:. You could start a program to download the file, save it on your local disk and then start Vim to edit it. There is a much simpler way. Move the cursor to any character of the URL. Then use this command: gf With a bit of luck, Vim will figure out which program to use for downloading the file, download it and edit the copy. To open the file in a new window use CTRL-W f. If something goes wrong you will get an error message.

It's possible that the URL is wrong, you don't have permission to read it, the network connection is down, etc. Unfortunately, it's hard to tell the cause of the error. You might want to try the manual way of downloading the file. Accessing files over the internet works with the netrw plugin. Currently URLs with these formats are recognized:. Vim doesn't do the communication itself, it relies on the mentioned programs to be available on your computer.

On most Unix systems "ftp" and "rcp" will be present. Vim detects these URLs for each command that starts editing a new file, also with ":edit" and ":split", for example. For more information, also about passwords, see netrw. You can edit binary files with Vim.

Vim wasn't really made for this, thus there are a few restrictions. But you can read a file, change a character and write it back, with the result that only that one character was changed and the file is identical otherwise. To make sure that Vim does not use its clever tricks in the wrong way, add the "-b" argument when starting Vim: vim -b datafile This sets the 'binary' option.

The effect of this is that unexpected side effects are turned off. For example, 'textwidth' is set to zero, to avoid automatic formatting of lines. And files are always read in Unix file format.

Binary mode can be used to change a message in a program. Be careful not to insert or delete any characters, it would stop the program from working. Use "R" to enter replace mode. Many characters in the file will be unprintable. There might not be many line breaks in the file. To get some overview switch the 'wrap' option off: :set nowrap BYTE POSITION. To see on which byte you are in the file use this command: g CTRL-G The output is verbose:.

Col of ; Line of ; Word of ; Byte of The last two numbers are the byte position in the file and the total number of bytes.

This takes into account how 'fileformat' changes the number of bytes that a line break uses. To move to a specific byte in the file, use the "go" command. For example, to move to byte go USING XXD. A real binary editor shows the text in two ways: as it is and in hex format. You can do this in Vim by first converting the file with the "xxd" program. This comes with Vim. xxd The text will look like this:. You can now view and edit the text as you like. Vim treats the information as ordinary text.

Changing the hex does not cause the printable character to be changed, or the other way around. xxd -r Only changes in the hex part are used. Changes in the printable text part on the right are ignored. This is easy: You can edit a compressed file just like any other file. The "gzip" plugin takes care of decompressing the file when you edit it. And compressing it again when you write it. These compression methods are currently supported:. Vim uses the mentioned programs to do the actual compression and decompression.

You might need to install the programs first. txt Inserting quickly. DOS, Mac and Unix files USING THE MAC FORMAT. Binary files BYTE POSITION.

Many characters in the file will be unprintable. it ' is working 'function. With some restrictions, binary files can be edited as well. Also see 'backupcopy' and crontab. If there is not enough room, only the first few files get a window. See also: ui-startup channel-stdio.
