*funcref* create lazier function references. Pass arguments to create closure
|
||
|
|
like function calls

HOWTO~
|
||
|
|
|
||
|
|
Use *funcref#Function* to create a special dict called
|
||
|
|
*faked-function-reference* which can be called by *funcref#Call*
|
||
|
|
>
|
||
|
|
{ 'faked_function_reference': 'file#FuncName' }
|
||
|
|
< passing some arguments and / or self: >
|
||
|
|
{ 'faked_function_reference': 'MyFunc', 'args': [1,2], 'self' : { a object ] }
|
||
|
|
< You can also create lambda like functions which will be evaled: >
|
||
|
|
{ 'faked_function_reference': 'return ARGS[1]' }
|

|

|
REASONS ~
|
||
|
|
Creating a Vim funcref pointing to an autoload function will make Vim source
|
||
|
|
that file. This is not lazy enough. (Seems to be no longer true? Has this changed?)
|
||
|
|
|
||
|
|
A Vim function reference neither allows attaching arguments nor self.
|
||
|
|
|
||
|
|
Don't care about case of variables. Normally when using Vim function
|
||
|
|
references you have to use variable names starting with an upper case letter

Example: ~
|
||
|
|
>
|
||
|
|
let f = funcref#Function('return ARGS[0].ARGS[1].SELF["key"]',{'args':[3], 'self':{'key': 'value'} })
|
||
|
|
echo funcref#Call(f, [2])
|
||
|
|
" prints "32value"
|
||
|
|
|
||
|
|
echo funcref#Call('no value')
|
||
|
|
<
|
||
|
|
echo funcref#Call(f, [2])
