Should use @static when conditioning on the OS inside a function
There was a problem hiding this comment.
not unless you're emitting code that doesn't compile on multiple platforms, or you really need to eliminate the comparison for runtime performance. better to leave the static out if neither is the case, have all branches at least get compiled.

I think on v0.6, code is conditionally compiled with and without @static
So maybe there's no runtime performance difference?
Both test1() and test2() produce the same llvm:
test1() = is_windows() ? 1 : "a"
test2() = @static is_windows() ? 1 : "a"
julia> @code_llvm test1()
; Function Attrs: uwtable
define i64 @julia_test1_68517() #0 !dbg !5 {
top:
ret i64 1
}
julia> @code_llvm test2()
; Function Attrs: uwtable
define i64 @julia_test2_68518() #0 !dbg !5 {
top:
ret i64 1
}

Take 2 for #20776
(I made a mistake with GitHub when trying to modify that PR, sorry)
Summary:
JULIA_SHELLcan be set to:cmdis default for Windows users.For Windows, the raw line is processed, rather than converting to
Cmdand then re-assembling into a Windows command line. Windows shell commands are passed as a string anyway, so this gives the user more control over any escaping. I think it works quite well.Modified special handling of
cd. When there are 2 or more arguments, command line is processed as normal, rather than throwing an error. This allows commands such ascd $dir && $commandto be executed.
