EXPORTED TERMS
This module exports terms (not subroutines), so you don't need to use parentheses to avoid block gobbling errors. Just use these same way as you'd use constant π
If you have to use parens for some reason, make them go around the whole them, not just the args:
make-temp-path(:content<foo> :chmod<423>) # WRONG
(make-temp-path :content<foo> :chmod<423>) # RIGHT
make-temp-path
Defined as:
sub term:<make-temp-path> (
:$content where Any|Blob:D|Cool:D,
Int :$chmod,
Str() :$prefix = '',
Str() :$suffix = ''
--> IO::Path:D
)
Creates an IO::Path object pointing to a path inside $*TMPDIR that will be deleted (see DETAILS OF DELETION section below).
Unless :$chmod or :$content are given, no files will be created. If :$chmod is given a file containing :$content (or empty, if no :$content is given) will be created with $chmod permissions. If :$content is given without :$chmod, the mode will be the default resulting from files created with IO::Handle.open.
The basename of the path is currently a SHA256 hash, but your program should not make assumptions about the format of the basename.
Security Note: at the moment, :chmod is set after the file is created and its content is written. This will be fixed once a way to create a file with a specific mode is available in Rakudo. While it will work at the moment, it might not be the best idea to assume :$content will be successfully written if you set :$chmod that does not let the current process write to the file.
make-temp-dir
Defined as:
sub term:<make-temp-dir> (Int :$chmod, Str() :$prefix = '', Str() :$suffix = '' --> IO::Path:D)
Creates a directory inside $*TMPDIR that will be deleted (see DETAILS OF DELETION section below) and returns the IO::Path object pointing to it.
If :$chmod is provided, the directory will be created with that mode. Otherwise, the default .mkdir mode will be used.
Note that currently .mkdir pays attention to umask and make-temp-dir will first the :$chmod to .mkdir, to create umask masked directory, and then it will .chmod it, to remove the effects of the umask.
DETAILS OF DELETION
The deletion of files created by this module will happen either when the returned IO::Path objects are garbage collected or when the END phaser gets run. Note that this means temporary files/directories may be left behind if your program crashes or gets aborted.
The temporary IO::Path objects created by make-temp-path and make-temp-dir terms have a role Temp::Path::AutoDel mixed in that will rmtree or .unlink the filesystem object the path points to.
Note that deletion will happen only if the path was created by this module. For example doing make-temp-dir.sibling: 'foo' will still give you an IO::Path with Temp::Path::AutoDel mixed in due to how IO::Path methods create new objects. But new objects created by .sibling, .add, .child, .parent, etc won't be deleted, when the object gets garbage collected, because you created it and not the module. Of course, when a parent directory, that was created by this module gets deleted, all its contents that you created with .child gets removed from the disk. Siblings need to be removed manually.
