When giving - as the program, read code from standard in.

I couldn't figure out another way of passing args while reading from stdin. This seems to be what python does (for example):

$ julia - foo bar <<EOF
println(ARGS)
EOF
["foo", "bar"]

$ python - foo bar <<EOF
import sys; print(sys.argv)
EOF
['-', 'foo', 'bar']

It is perhaps a bit strange that this takes another code path compared to

julia <<EOF
...
EOF

since that ends up all the way in here:

julia/base/client.jl

Line 412 in ae336ab

if isa(input, File) || isa(input, IOStream)

but not sure it matters much.

julia <<EOF
...
EOF

Shouldn't we just make this work? If we're already autoswitching based on stream type detection, why not at least make it useful.

Shouldn't we just make this work?

It does work, just ends up taking a different path than what I implemented here.

Bump.

I guess this can now be changed to passing -?

julia/base/loading.jl

Lines 1406 to 1413 in 2ed3ec4

	io = open(pipeline(`$(julia_cmd()::Cmd) -O0
	--output-ji $output --output-incremental=yes
	--startup-file=no --history-file=no --warn-overwrite=yes
	--color=$(have_color === nothing ? "auto" : have_color ? "yes" : "no")
	$trace
	--eval 'eval(Meta.parse(read(stdin,String)))'`, stderr = internal_stderr, stdout = internal_stdout),
	"w", stdout)

True, that would seem to be identical now
