Hi All,

If Squeak is running headless and something is sent to Transcript, what happens?

Unless you have the CommandLineToolset set as default, nothing.

Hi Tobias,

Thanks, that's what I thought, I just wanted to be sure.

IMO we should change this and have output go to stdout if headless, and hence include CommandLineToolset in the base image.  One can always unload it if it's not wanted.  But this is a better default.

It's already there. You just have to use it when headless.

Or set the "Redirect transcript to stdout" preference, which redirects
the transcript to standard output. It works well in trunk now.

I expect that just evaluating "TranscriptStream redirectToStdOut: true"
in the headless image is probably sufficient in this case (but no objection
to adding CommandLineToolset if it also has value).

I am wrong. CommandLineToolSet just handles debugging requests, The redirection is directly as Dave pointed out.
Should I be wrong? Shouldn't the (btw already present) CommandLineToolSet also make sure the redirection is there
when it is selected?

Hmmmm.......   That's a good question, as well, for SmalltalkImage>>#run:.

Personally, I don't care for making references to Transcript in code
anymore.  It's just as easy to signal Notifications, Warnings, and
Errors and doing so helps proper error-handling develop from the
get-go.
