Last change: 2006 Apr 24 - - - VIM REFERENCE MANUAL by Bram Moolenaar - - -This document lists the incompatible differences between Vim 3.0 and Vim 4.0. -Although 4.0 is mentioned here, this is also for version 4.1, 4.2, etc.. - -This file is important for everybody upgrading from Vim 3.0. Read it -carefully to avoid unexpected problems. - -'backup' option default changed |backup-changed| -Extension for backup file changed |backup-extension| -Structure of swap file changed |swapfile-changed| -"-w scriptout" argument changed |scriptout-changed| -Backspace and Delete keys |backspace-delete| -Escape for | changed |escape-bar| -Key codes changed |key-codes-changed| -Terminal options changed |termcap-changed| -'errorformat' option changed |errorformat-changed| -'graphic' option gone |graphic-option-gone| -'yankendofline' option gone |ye-option-gone| -'icon' and 'title' default value changed |icon-changed| -'highlight' option changed |highlight-changed| -'tildeop' and 'weirdinvert' short names changed |short-name-changed| -Use of "v", "V" and "CTRL-V" in Visual mode |use-visual-cmds| -CTRL-B in Insert mode removed |toggle-revins| - - -'backup' option default changed *backup-changed* -------------------------------- - -The default value for 'backup' used to be on. This resulted in a backup file -being made when the original file was overwritten. - -Now the default for 'backup' is off. As soon as the writing of the file has -successfully finished, the backup file is deleted. If you want to keep the -backup file, set 'backup' on in your vimrc. The reason for this change is -that many people complained that leaving a backup file behind is not -Vi-compatible. |'backup'| - - -Extension for backup file changed *backup-extension* ---------------------------------- - -The extension for the backup file used to be ".bak". Since other programs -also use this extension and some users make copies with this extension, it was -changed to the less obvious "~". Another advantage is that this takes less -space, which is useful when working on a system with short file names. For -example, on MS-DOS the backup files for "longfile.c" and "longfile.h" would -both become "longfile.bak"; now they will be "longfile.c~" and "longfile.h~". - -If you prefer to use ".bak", you can set the 'backupext' option: > - :set bex=.bak - - -Structure of swap file changed *swapfile-changed* ------------------------------- - -The contents of the swap file were extended with several parameters. Vim -stores the user name and other information about the edited file to make -recovery more easy and to be able to know where the swap file comes from. The -first part of the swap file can now be understood on a machine with a -different byte order or sizeof(int). When you try to recover a file on such a -machine, you will get an error message that this is not possible. - -Because of this change, swap files cannot be exchanged between 3.0 and 4.0. -If you have a swap file from a crashed session with 3.0, use Vim 3.0 to -recover the file---don't use 4.0. |swap-file| - - -"-w scriptout" argument changed *scriptout-changed* -------------------------------- - -"vim -w scriptout" used to append to the scriptout file. Since this was -illogical, it now creates a new file. An existing file is not overwritten -(to avoid destroying an existing file for those who rely on the appending). -[This was removed again later] |-w| - - -Backspace and Delete keys *backspace-delete* -------------------------- - -In 3.0 both the delete key and the backspace key worked as a backspace in -insert mode; they deleted the character to the left of the cursor. In 4.0 the -delete key has a new function: it deletes the character under the cursor, just -like it does on the command-line. If the cursor is after the end of the line -and 'bs' is set, two lines are joined. |<Del>| |i_<Del>| - -In 3.0 the backspace key was always defined as CTRL-H and delete as CTRL-?. -In 4.0 the code for the backspace and delete key is obtained from termcap or -termlib, and adjusted for the "stty erase" value on Unix. This helps people -who define the erase character according to the keyboard they are working on. - |<BS>| |i_<BS>| - -If you prefer backspace and delete in Insert mode to have the old behavior, -put this line in your vimrc: - - inoremap ^? ^H - -And you may also want to add these, to fix the values for <BS> and <Del>: - - set t_kb=^H - set t_kD=^? - -(Enter ^H with CTRL-V CTRL-H and ^? with CTRL-V CTRL-? or <Del>.) - -If the value for t_kb is correct, but the t_kD value is not, use the ":fixdel" -command. It will set t_kD according to the value of t_kb. This is useful if -you are using several different terminals. |:fixdel| - -When ^H is not recognized as <BS> or <Del>, it is used like a backspace. - - -Escape for | changed *escape-bar* --------------------- - -When the 'b' flag is present in 'cpoptions', the backslash cannot be used to -escape '|' in mapping and abbreviate commands, only CTRL-V can. This is -Vi-compatible. If you work in Vi-compatible mode and had used "\|" to include -a bar in a mapping, this needs to be replaced by "^V|". See |:bar|. - - -Key codes changed *key-codes-changed* ------------------ - -The internal representation of key codes has changed dramatically. In 3.0 a -one-byte code was used to represent a key. This caused problems with -different characters sets that also used these codes. In 4.0 a three-byte -code is used that cannot be confused with a character. |key-notation| - -If you have used the single-byte key codes in your vimrc for mappings, you -will have to replace them with the 4.0 codes. Instead of using the three-byte -code directly, you should use the symbolic representation for this in <>. See -the table below. The table also lists the old name, as it was used in the 3.0 -documentation. - -The key names in <> can be used in mappings directly. This makes it possible -to copy/paste examples or type them literally. The <> notation has been -introduced for this |<>|. The 'B' and '<' flags must not be present in -'cpoptions' to enable this to work |'cpoptions'|. - -old name new name old code old MS-DOS code ~ - hex dec hex dec ~ -<ESC> <Esc> -<TAB> <Tab> -<LF> <NL> <NewLine> <LineFeed> -<SPACE> <Space> -<NUL> <Nul> -<BELL> <Bell> -<BS> <BS> <BackSpace> -<INSERT> <Insert> -<DEL> <Del> <Delete> -<HOME> <Home> -<END> <End> -<PAGE_UP> <PageUp> -<PAGE_DOWN> <PageDown> - -<C_UP> <Up> 0x80 128 0xb0 176 -<C_DOWN> <Down> 0x81 129 0xb1 177 -<C_LEFT> <Left> 0x82 130 0xb2 178 -<C_RIGHT> <Right> 0x83 131 0xb3 179 -<SC_UP> <S-Up> 0x84 132 0xb4 180 -<SC_DOWN> <S-Down> 0x85 133 0xb5 181 -<SC_LEFT> <S-Left> 0x86 134 0xb6 182 -<SC_RIGHT> <S-Right> 0x87 135 0xb7 183 - -<F1> <F1> 0x88 136 0xb8 184 -<F2> <F2> 0x89 137 0xb9 185 -<F3> <F3> 0x8a 138 0xba 186 -<F4> <F4> 0x8b 139 0xbb 187 -<F5> <F5> 0x8c 140 0xbc 188 -<F6> <F6> 0x8d 141 0xbd 189 -<F7> <F7> 0x8e 142 0xbe 190 -<F8> <F8> 0x8f 143 0xbf 191 -<F9> <F9> 0x90 144 0xc0 192 -<F10> <F10> 0x91 145 0xc1 193 - -<SF1> <S-F1> 0x92 146 0xc2 194 -<SF2> <S-F2> 0x93 147 0xc3 195 -<SF3> <S-F3> 0x94 148 0xc4 196 -<SF4> <S-F4> 0x95 149 0xc5 197 -<SF5> <S-F5> 0x96 150 0xc6 198 -<SF6> <S-F6> 0x97 151 0xc7 199 -<SF7> <S-F7> 0x98 152 0xc8 200 -<SF8> <S-F8> 0x99 153 0xc9 201 -<SF9> <S-F9> 0x9a 154 0xca 202 -<SF10> <S-F10> 0x9b 155 0xcb 203 - -<HELP> <Help> 0x9c 156 0xcc 204 -<UNDO> <Undo> 0x9d 157 0xcd 205 - - (not used) 0x9e 158 0xce 206 - (not used) 0x9f 159 0xcf 207 - - -Terminal options changed *termcap-changed* ------------------------- - -The names of the terminal options have been changed to match the termcap names -of these options. All terminal options now have the name t_xx, where xx is -the termcap name. Normally these options are not used, unless you have a -termcap entry that is wrong or incomplete, or you have set the highlight -options to a different value. |terminal-options| - -Note that for some keys there is no termcap name. Use the <> type of name -instead, which is a good idea anyway. - -Note that "t_ti" has become "t_mr" (invert/reverse output) and "t_ts" has -become "t_ti" (init terminal mode).

The first -format that matches is used. The default values have been adjusted to catch -the most common formats. |errorformat| - -If you have a format that contains a comma, it needs to be preceded with a -backslash. Type two backslashes, because the ":set" command will eat one. - - -'graphic' option gone *graphic-option-gone* ---------------------- - -The 'graphic' option was used to make the characters between <~> and 0xa0 -display directly on the screen. Now the 'isprint' option takes care of this -with many more possibilities. The default setting is the same; you only need -to look into this if you previously set the 'graphic' option in your vimrc. - |'isprint'| - - -'yankendofline' option gone *ye-option-gone* ---------------------------- - -The 'yankendofline' option has been removed. Instead you can just use - :map Y y$ - - -'icon' and 'title' default value changed *icon-changed* ----------------------------------------- - -The 'title' option is now only set by default if the original title can be -restored. Avoids "Thanks for flying Vim" titles. If you want them anyway, -put ":set title" in your vimrc. |'title'| - -The default for 'icon' now depends on the possibility of restoring the -original value, just like 'title'. If you don't like your icon titles to be -changed, add this line to your vimrc: |'icon'| - :set noicon - - -'highlight' option changed *highlight-changed* --------------------------- - -The 'i' flag now means italic highlighting, instead of invert. The 'r' flag -is used for reverse highlighting, which is what 'i' used to be. Normally you -won't see the difference, because italic mode is not supported on most -terminals and reverse mode is used as a fallback. |'highlight'| - -When an occasion is not present in 'highlight', use the mode from the default -value for 'highlight', instead of reverse mode. - - -'tildeop' and 'weirdinvert' short names changed *short-name-changed* ------------------------------------------------ - -Renamed 'to' (abbreviation for 'tildeop') to 'top'. |'tildeop'| -Renamed 'wi' (abbreviation for 'weirdinvert') to 'wiv'. |'weirdinvert'| - -This was done because Vi uses 'wi' as the short name for 'window' and 'to' as -the short name for 'timeout'. This means that if you try setting these -options, you won't get an error message, but the effect will be different. - - -Use of "v", "V" and "CTRL-V" in Visual mode *use-visual-cmds* -------------------------------------------- - -In Visual mode, "v", "V", and "CTRL-V" used to end Visual mode. Now this -happens only if the Visual mode was in the corresponding type. Otherwise the -type of Visual mode is changed. Now only ESC can be used in all circumstances -to end Visual mode without doing anything. |v_V| - - -CTRL-B in Insert mode removed *toggle-revins* ------------------------------ - -CTRL-B in Insert mode used to toggle the 'revins' option. If you don't know -this and accidentally hit CTRL-B, it is very difficult to find out how to undo -it. Since hardly anybody uses this feature, it is disabled by default. If -you want to use it, define RIGHTLEFT in feature.h before compiling. |'revins'| - - vim:tw=78:ts=8:ft=help:norl: |
