Returns IO::Path representing new $*CWD on success. On failure, returns Failure and leaves $*CWD untouched. The $path can be any object with an IO method that returns an IO::Path object. The available file tests are: ... By default, only :d test is performed.

At creation, each IO::Path object is given information about the current working directory the path might be relative to using the $.CWD attribute (defaults to $*CWD), as well as what operating system semantics should be used for path manipulation using the special IO::Spec type given in the $.SPEC attribute.

$ perl6 work_dir01.p6 /opt/tor-browser /opt/rakudo /usr/src /usr/sbin /usr/lib32 /usr/lib64 /usr/share /usr/lib IO::Path · chdir - changes the current working directory. The current working directory can be read from the $*CWD variable.

The two extra attributes—SPEC and CWD—specify what type of operating system semantics the path should use as well as the "current working directory" for the path, i.e. if it's a relative path, then it's relative to that directory. This means that regardless of how you made one, an IO::Path ...

The :$CWD argument allows for explicit control over the base directory for relative paths, which is particularly useful in testing or when working with paths in different contexts. Sounds like if you do not put the path of your program in and it is not in the default path, that you can set ...

Also creates parent directories, as needed (similar to *nix utility mkdir with -p option); that is, mkdir "foo/bar/ber/meow" will create foo, foo/bar, and foo/bar/ber directories if they do not exist, as well as foo/bar/ber/meow. ... Changes value of $*CWD variable to the provided $path, optionally ensuring the new path passes several file tests.

Notice that $*CWD returns the current working directory. Then we created a new Raku subroutine called hellofromc() that should act as a wrapper to its counterpart C function having the same name and residing in the C library found in LIBPATH. All of this was done by using the is native trait.

It is an error to run a thread that has already been started. See primary documentation in context for sub run. ... sub run( *@args ($, *@), :$in = '-', :$out = '-', :$err = '-', Bool :$bin = False, Bool :$chomp = True, Bool :$merge = False, Str:D :$enc = 'UTF-8', Str:D :$nl = "\n", :$cwd = ...

Since the tests are performed against Str arguments, not IO, the tests are executed in the $*CWD, instead of the target directory.

I am missing what run does with (not finding them in https://docs.raku.org/routine/run) :$cwd :$env :$arg0 and :$win-verbatim-args This is what I have so far: method new(Proc:U: :$in = '-', :$out = '-', :$err = '-', Bool :$bin = False, Bool :$chomp = True, Bool :$merge = False, Str:D :$enc = 'UTF-8', Str:D :$nl = "\n", --> Proc:D) sub run( *@args ($, *@), :$in = '-', # use `:$in`, `$:out`, and `:$err` arguments to redirect to # different file handle, thus creating a kind of pipe

multi shell($cmd, :$in = '-', :$out = '-', :$err = '-', Bool :$bin, Bool :$chomp = True, Bool :$merge, Str :$enc, Str:D :$nl = "\n", :$cwd = $*CWD, :$env) Runs a command through the system shell, which defaults to %*ENV<ComSpec> /c in Windows, /bin/sh -c otherwise.

The main subroutine is collect. It requires a file config.raku to be in the $CWD (current working directory). In CRD the executable Raku-Doc initiates the collection by setting up sources and installing a config.raku file.

See docs.raku.org/language/variables#index-entry-$*CWD for more information about $*CWD. (Note that it is possible to change it manually, even to illegal values.

At creation, each IO::Path object is given information about the current working directory the path might be relative to using the $.CWD attribute (defaults to $*CWD), as well as what operating system semantics should be used for path manipulation using the special IO::Spec type given in the $.SPEC attribute.

December 2, 2022 - To get the gist of what the variable is: To see a variable’s contents call raku on it or pass it to the builtin data dumper function (dd): Why does a $*CWD variable work like that? Just ask WHY … · Or even HOW the variable works – it’s Higher Order Workings, can be accessed with ^ like so: Raku variables include everything you need to understand how to use them.

Here is a small example that prints the first ten FileChanged-notifications for the current working directory: Raku highlighting · my $finish = Promise.new; my $count = 0; IO::Notification.watch-path($*CWD).act( -> $change { $count++ if $change.event ~~ FileChanged; say "($count) $change.path(): $change.event()"; $finish.keep if $count >= 10; }); await $finish; The type of the change is very much dependent both on the platform and on specific system calls that were used to initiate the change.

IO::Path::Win32.new("foo/bar").raku.say; # OUTPUT: IO::Path::Win32.new("foo/bar", :CWD("C:\\Users\\camelia")) Note that this string includes the value of the .CWD attribute that is set to $*CWD when the path object was created, by default.

I hope this helps you understand why there isn't a 'boo boo' in the documentation, and why what others have said is actually answering the question you asked.
