*v:false* *false-variable*
v:false A Number with value zero. Used to put "false" in JSON. See
|jsonencode()|.
+ When used as a string this evaluates to "false". >
+ echo v:false
+< false ~
*v:fcs_reason* *fcs_reason-variable*
v:fcs_reason The reason why the |FileChangedShell| event was triggered.
v:hlsearch Variable that indicates whether search highlighting is on.
Setting it makes sense only if 'hlsearch' is enabled which
requires |+extra_search|. Setting this variable to zero acts
- the like |:nohlsearch| command, setting it to one acts like >

let &hlsearch = &hlsearch
< Note that the value is restored when returning from a
function. |function-search-undo|.
*v:none* *none-variable*
v:none An empty String. Used to put an empty item in JSON. See
|jsonencode()|.
+ When used as a number this evaluates to zero.
+ When used as a string this evaluates to "none". >
+ echo v:none
+< none ~
*v:null* *null-variable*
v:null An empty String. Used to put "null" in JSON. See
|jsonencode()|.
+ When used as a number this evaluates to zero.
+ When used as a string this evaluates to "null". >
+ echo v:null
+< null ~
*v:oldfiles* *oldfiles-variable*
v:oldfiles List of file names that is loaded from the |viminfo| file on
*v:true* *true-variable*
v:true A Number with value one. Used to put "true" in JSON. See
|jsonencode()|.
-
+ When used as a string this evaluates to "true". >
+ echo v:true
+< true ~
*v:val* *val-variable*
v:val Value of the current item of a |List| or |Dictionary|. Only
valid while evaluating the expression used with |map()| and
The opposite function is |split()|.
jsondecode({string}) *jsondecode()*
- TODO
+ This parses a JSON formatted string and returns the equivalent
+ in Vim values. See |jsonencode()| for the relation between
+ JSON and Vim values.
+ The decoding is permissive:
+ - A trailing comma in an array and object is ignored.
+ - An empty item in an array results in v:none.
+ - When an object name is not a string it is converted to a
+ string. E.g. the number 123 is used as the string "123".
+ - More floating point numbers are recognized, e.g. "1." for
+ "1.0".
jsonencode({expr}) *jsonencode()*
- Encodode {expr} as JSON and return this as a string.
+ Encode {expr} as JSON and return this as a string.
The encoding is specified in:
http://www.ietf.org/rfc/rfc4627.txt
Vim values are converted as follows:
Number decimal number
Float floating point number
String in double quotes (possibly null)
- Funcref nothing
+ Funcref not possible, error
List as an array (possibly null); when
used recursively: []
Dict as an object (possibly null); when
v:true "true"
v:none nothing
v:null "null"
+ Note that using v:none is permitted, although the JSON
+ standard does not allow empty items. This can be useful for
+ omitting items in an array:
+ [0,,,,,5] ~
+ This is much more efficient than:
+ [0,null,null,null,null,5] ~
+ But a strict JSON parser will not accept it.
keys({dict}) *keys()*
Return a |List| with all the keys of {dict}. The |List| is in
List: 3
Dictionary: 4
Float: 5
+ Boolean: 6 (v:false and v:true)
+ None 7 (v:null and v:none)
To avoid the magic numbers it should be used this way: >
:if type(myvar) == type(0)
:if type(myvar) == type("")
:if type(myvar) == type([])
:if type(myvar) == type({})
:if type(myvar) == type(0.0)
+ :if type(myvar) == type(v:false)
+ :if type(myvar) == type(v:none
undofile({name}) *undofile()*
Return the name of the undo file that would be used for a file
