NVIM REFERENCE MANUAL
|
|
|
|
|
|
Predefined variables *vvars*
|
|
|
|
Some variables can be set by the user, but the type cannot be changed.
|
|
|
|
Type |gO| to see the table of contents.
|
|
|
|
*v:argv* *argv-variable*
|
|
v:argv
|
|
The command line arguments Vim was invoked with. This is a
|
|
list of strings. The first item is the Vim command.
|
|
See |v:progpath| for the command with full path.
|
|
|
|
*v:char* *char-variable*
|
|
v:char
|
|
Argument for evaluating 'formatexpr' and used for the typed
|
|
character when using <expr> in an abbreviation |:map-<expr>|.
|
|
It is also used by the |InsertCharPre| and |InsertEnter| events.
|
|
|
|
*v:charconvert_from* *charconvert_from-variable*
|
|
v:charconvert_from
|
|
The name of the character encoding of a file to be converted.
|
|
Only valid while evaluating the 'charconvert' option.

|
|
The name of the character encoding of a file after conversion.
|
|
Only valid while evaluating the 'charconvert' option.
|
|
|
|
*v:cmdarg* *cmdarg-variable*
|
|
v:cmdarg
|
|
The extra arguments ("++p", "++enc=", "++ff=") given to a file
|
|
read/write command. This is set before an autocommand event
|
|
for a file read/write command is triggered. There is a
|
|
leading space to make it possible to append this variable
|
|
directly after the read/write command. Note: "+cmd" isn't
|
|
included here, because it will be executed anyway.
|
|
|
|
*v:cmdbang* *cmdbang-variable*
|
|
v:cmdbang
|
|
Set like v:cmdarg for a file read/write command. When a "!"
|
|
was used the value is 1, otherwise it is 0. Note that this
|
|
can only be used in autocommands. For user commands |<bang>|
|
|
can be used.
|
|
|
|
*v:collate* *collate-variable*
|
|
v:collate
|
|
The current locale setting for collation order of the runtime
|
|
environment. This allows Vim scripts to be aware of the
|
|
current locale encoding. Technical: it's the value of
|
|
LC_COLLATE. When not using a locale the value is "C".
|
|
This variable can not be set directly, use the |:language|
|
|
command.
|
|
See |multi-lang|.
|
|
|
|
*v:completed_item* *completed_item-variable*
|
|
v:completed_item
|
|
Dictionary containing the most recent |complete-items| after
|
|
|CompleteDone|. Empty if the completion failed, or after
|
|
leaving and re-entering insert mode.
|
|
Note: Plugins can modify the value to emulate the builtin
|
|
|CompleteDone| event behavior.
|
|
|
|
*v:count* *count-variable*
|
|
v:count
|
|
The count given for the last Normal mode command. Can be used
|
|
to get the count before a mapping. Read-only. Example: >vim
|
|
:map _x :<C-U>echo "the count is " .. v:count<CR>
|
|
<
|
|
Note: The <C-U> is required to remove the line range that you
|
|
get when typing ':' after a count.
|
|
When there are two counts, as in "3d2w", they are multiplied,
|
|
just like what happens in the command, "d6w" for the example.
|
|
Also used for evaluating the 'formatexpr' option.
|
|
|
|
*v:count1* *count1-variable*
|
|
v:count1
|
|
Just like "v:count", but defaults to one when no count is
|
|
used.
|
|
|
|
*v:ctype* *ctype-variable*
|
|
v:ctype
|
|
The current locale setting for characters of the runtime
|
|
environment. This allows Vim scripts to be aware of the
|
|
current locale encoding. Technical: it's the value of
|
|
LC_CTYPE. When not using a locale the value is "C".
|
|
This variable can not be set directly, use the |:language|
|
|
command.
|
|
See |multi-lang|.
|
|
|
|
*v:dying* *dying-variable*
|
|
v:dying
|
|
Normally zero. When a deadly signal is caught it's set to
|
|
one. When multiple signals are caught the number increases.
|
|
Can be used in an autocommand to check if Vim didn't
|
|
terminate normally.
|
|
Example: >vim
|
|
:au VimLeave * if v:dying | echo "\nAAAAaaaarrrggghhhh!!!\n" | endif
|
|
<
|
|
Note: if another deadly signal is caught when v:dying is one,
|
|
VimLeave autocommands will not be executed.
|
|
|
|
*v:echospace* *echospace-variable*
|
|
v:echospace
|
|
Number of screen cells that can be used for an `:echo` message
|
|
in the last screen line before causing the |hit-enter-prompt|.
|
|
Depends on 'showcmd', 'ruler' and 'columns'. You need to
|
|
check 'cmdheight' for whether there are full-width lines
|
|
available above the last line.
|
|
|
|
*v:errmsg* *errmsg-variable*
|
|
v:errmsg
|
|
Last given error message.
|
|
Modifiable (can be set).
|
|
Example: >vim
|
|
let v:errmsg = ""
|
|
silent! next
|
|
if v:errmsg != ""
|
|
" ... handle error
|
|
<
|
|
|
|
*v:errors* *errors-variable* *assert-return*
|
|
v:errors
|
|
Errors found by assert functions, such as |assert_true()|.
|
|
This is a list of strings.
|
|
The assert functions append an item when an assert fails.
|
|
The return value indicates this: a one is returned if an item
|
|
was added to v:errors, otherwise zero is returned.
|
|
To remove old results make it empty: >vim
|
|
let v:errors = []
|
|
<
|
|
If v:errors is set to anything but a list it is made an empty
|
|
list by the assert function.
|
|
|
|
*v:event* *event-variable*
|
|
v:event
|
|
Dictionary of event data for the current |autocommand|. Valid
|
|
only during the event lifetime; storing or passing v:event is
|
|
invalid! Copy it instead: >vim
|
|
au TextYankPost * let g:foo = deepcopy(v:event)
|
|
<
|
|

|
values for options such as

When the |shada| file is not used the List is empty.

Also see |:oldfiles| and |c_#<|.
|
|
The List can be modified, but this has no effect on what is

The value -1 is often used when the command could not be
|
|
executed. Read-only.

|
open for writing. Example: >vim
|
|
:call chansend(v:stderr, "error: toaster empty\n")
|
|
<

'd' Delete swapfile
|
|

|
|
no SwapExists autocommand. The default is empty.
|
|
|
|
*v:swapcommand* *swapcommand-variable*
|
|
v:swapcommand
