Parsing failure with as_symbols=true and commands_are_required=false #100

Closed alhirzel closed 3 years ago

alhirzel commented 4 years ago

Encountered what appears to be a corner case with symbols and commands.

using ArgParse, Test

s = ArgParseSettings()
s.commands_are_required = false

@add_arg_table! s begin
    "foobar"
        action = :command
end

@test isnothing(parse_args([], s)["%COMMAND%"])
@test isnothing(parse_args([], s; as_symbols=true)[:_COMMAND_])
Error During Test at /tmp/interesting.jl:12
  Test threw exception
  Expression: isnothing((parse_args([], s; as_symbols = true))[:_COMMAND_])

I also gets this error on Windows:

Any idea?

@carlobaldassi, Will it solve the issue I raised?

carlobaldassi commented 3 years ago

@RoyiAvital no, your issue seems to be unrelated. It looks like you are getting a complaint about the permissions fr deleting files. It looks like an issue with the julia installation or the packages directory.
