Re: Use of the --output flag
--output is for the compiler's compilation stages for example: > timo@schmand ~> perl6 --output=/tmp/outputtest --target=mbc -e 'say "hi"' > timo@schmand ~> moar --dump /tmp/outputtest | head > > MoarVM dump of binary compilation unit: > > SC_0 : B1DFAD9164F11E967B354508CC458ABAB8DEDC27 > SC_1 : D71FD1C8B1B40FC9B294068F2EC29C505914FDC6-0 > SC_2 : 0808522FF10EC773B02A4C55883CC154BB964DE2 > Callsite_0 : > num_pos: 0 > arg_count: 0 > Callsite_1 : Most of the compilation stages don't work with --output, which could be a bug. However, --output isn't supposed to change what $*OUT is set to in the script. Hope that helps - Timo On 09/10/2018 15:18, Simon Proctor wrote: > So...

Re: Use of the --output flag
It feels like a bug. I more wanted to know if anyone knew anything about it for the talk.

Re: Use of the --output flag
My guess is that this is a bug. You can work around it by adding my $*OUT = q[test].IO.open(:w); in front of the code. On Tue, Oct 9, 2018 at 8:18 AM Simon Proctor wrote: > > So...

Use of the --output flag
So... I'm working through some notes for a talk on Thursday and I am trying to work out how the --output flag is supposed to work. I would expect this to create a file called test and print "Hi\n" in it : perl6 --output=test -e 'say "Hi"' But instead I got Hi printed to the command line and an error : Use of Nil in string context in any print at gen/moar/stage2/NQPCORE.setting line 850 Trying use it on a sime file (say "Hi") and it also doesn't do that. (Note that the test file is created but it's empty). Any ideas? -- Simon Proctor Cognoscite aliquid novum cotidie http://www.khanate.co.uk/
