Expression that is evaluated to obtain the filename(s) for the |:find|
Function that is called to obtain the filename(s) for the |:find|
command. When this option is empty, the internal |file-searching|
mechanism is used.
While evaluating the expression, the |v:fname| variable is set to the
argument of the |:find| command.
The value can be the name of a function, a |lambda| or a |Funcref|.
See |option-value-function| for more information.
The expression is evaluated only once per |:find| command invocation.
The expression can process all the directories specified in 'path'.
The function is called with two arguments. The first argument is a
|String| and is the |:find| command argument. The second argument is
a |Boolean| and is set to |v:true| when the function is called to get
a List of command-line completion matches for the |:find| command.
The function should return a List of strings.
The expression may be evaluated for command-line completion as well,
in which case the |v:cmdcomplete| variable will be set to |v:true|,
otherwise it will be set to |v:false|.
The function is called only once per |:find| command invocation.
