This is fixed on latest master. Until I release a new version (hopefully soon) you can Pkg.checkout("ArgParse")
.
from argparse.jl.
I believe I over simplified my minimal example. I checkout out master 224ce77 to be sure. The following works when arg_type = Foo, but not when arg_type = Bar. The issue seems to actually be having print statements in parse_item methods.
using ArgParse
struct Foo end
function ArgParse.parse_item(::Type{Foo}, x::AbstractString)
return Foo()
end
struct Bar end
function ArgParse.parse_item(::Type{Bar}, x::AbstractString)
println()
return Bar()
end
settings = ArgParseSettings(description = "Argparse Test")
@add_arg_table settings begin
"--foo"
arg_type = Bar
required = true
nargs = '+'
end
argsDict = parse_args(settings)
from argparse.jl.
I see. After a short investigation, this seems like a Julia bug (still present in 0.7), whereby printing anything to stdout/stderr while the parsing is proceeding is causing all sorts of unexpected behavior. I'll try to find a minimal example and I'll open an issue.
from argparse.jl.
this is the culprit: JuliaLang/julia#27168
from argparse.jl.
