VIM REFERENCE MANUAL by Bram Moolenaar
Repeating commands, Vim scripts and debugging *repeating*
Chapter 26 of the user manual introduces repeating |usr_26.txt|.
1. Single repeats |single-repeat|
2. Multiple repeats |multi-repeat|
3. Complex repeats |complex-repeat|
4. Using Vim scripts |using-scripts|
5. Debugging scripts |debug-scripts|
6. Profiling |profiling|
==============================================================================
1. Single repeats *single-repeat*
*.*
. Repeat last change, with count replaced with [count].
Also repeat a yank command, when the 'y' flag is
included in 'cpoptions'. Does not repeat a
command-line command.
Simple changes can be repeated with the "." command. Without a count, the
count of the last change is used. If you enter a count, it will replace the
last one. If the last change included a specification of a numbered register,
the register number will be incremented. See |redo-register| for an example
how to use this. Note that when repeating a command that used a Visual
selection, the same SIZE of area is used, see |visual-repeat|.
*@:*
@: Repeat last command-line [count] times.
{not available when compiled without the
|+cmdline_hist| feature}
==============================================================================
2. Multiple repeats *multi-repeat*
*:g* *:global* *E147* *E148*
:[range]g[lobal]/{pattern}/[cmd]
Execute the Ex command [cmd] (default ":p") on the
lines within [range] where {pattern} matches.
:[range]g[lobal]!/{pattern}/[cmd]
Execute the Ex command [cmd] (default ":p") on the
lines within [range] where {pattern} does NOT match.
*:v* *:vglobal*
:[range]v[global]/{pattern}/[cmd]
Same as :g!.
Instead of the '/' which surrounds the {pattern}, you can use any other
single byte character, but not an alphanumeric character, '\', '"'' or '|'.
This is useful if you want to include a '/' in the search pattern or
replacement string.
For the definition of a pattern, see |pattern|.
The global commands work by first scanning through the [range] lines and
marking each line where a match occurs (for a multi-line pattern, only the
start of the match matters).
In a second scan the [cmd] is executed for each marked line with its line
number prepended. For ":v" and ":g!" the command is executed for each not
marked line. If a line is deleted its mark disappears.
The default for [range] is the whole buffer (1,$). Use "CTRL-C" to interrupt
the command. If an error message is given for a line, the command for that
line is aborted and the global command continues with the next marked or
unmarked line.
To repeat a non-Ex command, you can use the ":normal" command:
:g/pat/normal {commands}
Make sure that {commands} ends with a whole command, otherwise Vim will wait
for you to type the rest of the command for each match. The screen will not
have been updated, so you don't know what you are doing. See |:normal|.
The undo/redo command will undo/redo the whole global command at once.
The previous context mark will only be set once (with "''"' you go back to
where the cursor was before the global command).
The global command sets both the last used search pattern and the last used
substitute pattern (this is vi compatible). This makes it easy to globally
replace a string:
:g/pat/s//PAT/g
This replaces all occurrences of "pat" with "PAT". The same can be done with:
:%s/pat/PAT/g
Which is two characters shorter!
When using "global" in Ex mode, a special case is using ":visual" as a
command. This will move to a matching line, go to Normal mode to let you
execute commands there until you use |Q| to return to Ex mode. This will be
repeated for each matching line. While doing this you cannot use ":global".
To abort this type CTRL-C twice.
==============================================================================
3. Complex repeats *complex-repeat*
*q* *recording*
q{0-9a-zA-Z"} Record typed characters into register {0-9a-zA-Z"}
(uppercase to append). The 'q' command is disabled
while executing a register, and it doesn't work inside
a mapping and |:normal|. {Vi: no recording}
q Stops recording. (Implementation note: The 'q' that
stops recording is not stored in the register, unless
it was the result of a mapping) {Vi: no recording}
*@*
@{0-9a-z".=*} Execute the contents of register {0-9a-z".=*} [count]
times. Note that register '%' (name of the current
file) and '#' (name of the alternate file) cannot be
used.
The register is executed like a mapping, that means
that the difference between 'wildchar' and 'wildcharm'
applies.
For "@=" you are prompted to enter an expression. The
result of the expression is then executed.
See also |@:|. {Vi: only named registers}
*@@* *E748*
@@ Repeat the previous @{0-9a-z":*} [count] times.
:[addr]*{0-9a-z".=} *:@* *:star*
:[addr]@{0-9a-z".=*} Execute the contents of register {0-9a-z".=*} as an Ex
command. First set cursor at line [addr] (default is
current line). When the last line in the register does
not have a <CR> it will be added automatically when
the 'e' flag is present in 'cpoptions'.
Note that the ":*" command is only recognized when the
'*' flag is present in 'cpoptions'. This is NOT the
default when 'nocompatible' is used.
For ":@=" the last used expression is used. The
result of evaluating the expression is executed as an
Ex command.
Mappings are not recognized in these commands.
{Vi: only in some versions} Future: Will execute the
register for each line in the address range.
*:@:*
:[addr]@: Repeat last command-line. First set cursor at line
[addr] (default is current line). {not in Vi}
*:@@*
:[addr]@@ Repeat the previous :@{0-9a-z"}. First set cursor at
line [addr] (default is current line). {Vi: only in
some versions}
==============================================================================
4. Using Vim scripts *using-scripts*
For writing a Vim script, see chapter 41 of the user manual |usr_41.txt|.
*:so* *:source* *load-vim-script*
:so[urce] {file} Read Ex commands from {file}. These are commands that
start with a ":".
Triggers the |SourcePre| autocommand.
:so[urce]! {file} Read Vim commands from {file}. These are commands
that are executed from Normal mode, like you type
them.
When used after |:global|, |:argdo|, |:windo|,
|:bufdo|, in a loop or when another command follows
the display won't be updated while executing the
commands.
{not in Vi}
*:ru* *:runtime*
:ru[ntime][!] {file} ..
Read Ex commands from {file} in each directory given
by 'runtimepath'. There is no error for non-existing
files. Example:
:runtime syntax/c.vim
There can be multiple {file} arguments, separated by
spaces. Each {file} is searched for in the first
directory from 'runtimepath', then in the second
directory, etc. Use a backslash to include a space
inside {file} (although it's better not to use spaces
in file names, it causes trouble).
When [!] is included, all found files are sourced.
When it is not included only the first found file is
sourced.
When {file} contains wildcards it is expanded to all
matching files. Example:
:runtime! plugin/*.vim
This is what Vim uses to load the plugin files when
starting up. This similar command:
:runtime plugin/*.vim
would source the first file only.
When 'verbose' is one or higher, there is a message
when no file could be found.
When 'verbose' is two or higher, there is a message
about each searched file.
{not in Vi}
:scripte[ncoding] [encoding] *:scripte* *:scriptencoding* *E167*
Specify the character encoding used in the script.
The following lines will be converted from [encoding]
to the value of the 'encoding' option, if they are
different. Examples:
scriptencoding iso-8859-5
scriptencoding cp932
When [encoding] is empty, no conversion is done. This
can be used to restrict conversion to a sequence of
lines:
scriptencoding euc-jp
... lines to be converted ...
scriptencoding
... not converted ...
When conversion isn't supported by the system, there
is no error message and no conversion is done.
Don't use "ucs-2" or "ucs-4", scripts cannot be in
these encodings (they would contain NUL bytes).
When a sourced script starts with a BOM (Byte Order
Mark) in utf-8 format Vim will recognize it, no need
to use ":scriptencoding utf-8" then.
When compiled without the |+multi_byte| feature this
command is ignored.
{not in Vi}
*:scrip* *:scriptnames*
:scrip[tnames] List all sourced script names, in the order they were
first sourced. The number is used for the script ID
|<SID>|.
{not in Vi} {not available when compiled without the
|+eval| feature}
*:fini* *
