| disbot4 | <nahita3882> maybe it's a flushing issue? placing $*OUT.out-buffer = $*ERR.out-buffer = False; might be helpful if that's the case | 08:58 | |

| disbot4 | <Welemtam> Hi! thanks, flushes indeed make the traces work, but only until the shell command. Then nothing is displayed. Basically : $*OUT.out-buffer = $*ERR.out-buffer = False; # or just do $*ERR.flush after each 'note' call note 'hello'; # OK note 'hello 2'; # OK shell %vars<MAKE>, :cwd($srcdir); # nothing displayed note 'hello 3'; # Nothing , even with manual flushing zef.exe forks rakudo.exe to run that build script. This | 09:58 | |
| is why (imo) stderr is buffered (data goes through a pipe between rakudo.exe and zef.exe) Then rakudo.exe forks cmd.exe for the "shell" command and this is where things get broken | |||
| <jubilatious1_98524> Does run instead ot shell help? docs.raku.org/routine/run | 10:08 | ||

| disbot4 | <Welemtam> It does make the 3rd trace work, though the trace of what's executed are still invisible. And for some reason it makes the script return 0 and fail later At this point I'll try to write a more minimal sample 🙂 | 10:52 | |

| disbot4 | <jubilatious1_98524> Are you on WSL? Do pipes work differently there? Not well-versed in zef; I'm wondering if taking a gander at Raku's IO::CatHandle might spark some ideas (e.g. handle the piping yourself)? docs.raku.org/type/IO/CatHandle | 11:03 | |
| <jubilatious1_98524> The other idea (presented by @librasteve earlier) is there's something about your terminal session which requires you to do nohup (and/or & backgrounding) in WSL(2?). | 11:10 | ||
| <Welemtam> Nope it's pure native windows 🙂 | |||

| disbot4 | <jubilatious1_98524> Powershell? | 12:57 | |
| <Welemtam> the raku 'shell' command runs cmd.exe, not powershell If I run the whole thing from a powershell I get the same result (if that was your question) | 13:35 | ||

| disbot4 | <Welemtam> This may be an interesting "minimal" example - using run: class Foo { method build { say "hi!"; note "hi again!"; run 'nmake'; # something not in my path } } `raku.exe -e "require 'C:\Path\To\Foo.rakumod'; ::('Foo').new.build() ?? exit(0) !! exit(1);" -> std traces are printed -> run() result is not : it fails silently. Now if I add sub MAIN { Foo.new.build(); } to Foo.rakumod and run it with | 15:28 | |
| raku Foo.rakumod, the run result is displayed... | |||
