请问有人知道这个Expr的args的第一个索引位置上的那个Bool代表什么吗?
julia> macro f(a) dump(a) end
@f (macro with 2 methods)
julia> @f module S
end
Expr
head: Symbol module
args: Array{Any}((3,))
1: Bool true
2: Symbol S
3: Expr
head: Symbol block
args: Array{Any}((2,))
1: LineNumberNode
line: Int64 1
file: Symbol REPL[13]
2: LineNumberNode
line: Int64 2
file: Symbol REPL[13]
我猜是用来标注module
是否是一个baremodule
:
julia> :(module S end) |> dump
Expr
head: Symbol module
args: Array{Any}((3,))
1: Bool true
2: Symbol S
3: Expr
head: Symbol block
args: Array{Any}((2,))
1: LineNumberNode
line: Int64 1
file: Symbol REPL[1]
2: LineNumberNode
line: Int64 1
file: Symbol REPL[1]
julia> :(baremodule S end) |> dump
Expr
head: Symbol module
args: Array{Any}((3,))
1: Bool false
2: Symbol S
3: Expr
head: Symbol block
args: Array{Any}((2,))
1: LineNumberNode
line: Int64 1
file: Symbol REPL[2]
2: LineNumberNode
line: Int64 1
file: Symbol REPL[2]
