Returns the first advertised TupleSpace
.
Does this dependency require a prerelease?
Indicate if this NameTuple
is for a prerelease version.
A requirement is a prerelease if any of the versions inside of it are prereleases
A version is considered a prerelease if it contains a letter.
Creates a new SourceList
from an array of sources.
Returns an array of syntax error messages
If no missing pairs are found it falls back on the original error messages
Invoked by methods like Thread.join
, and by Mutex, to signify that current Fiber
is blocked until further notice (e.g. unblock
) or until timeout
has elapsed.
blocker
is what we are waiting on, informational only (for debugging and logging). There are no guarantee about its value.
Expected to return boolean, specifying whether the blocking operation was successful or not.
Invoked to wake up Fiber
previously blocked with block
(for example, Mutex#lock calls block
and Mutex#unlock calls unblock
). The scheduler should use the fiber
parameter to understand which fiber is unblocked.
blocker
is what was awaited for, but it is informational only (for debugging and logging), and it is not guaranteed to be the same value as the blocker
for block
.
Returns true
if this lock is currently held by some thread.
Attempts to grab the lock and waits if it isn’t available. Raises ThreadError
if mutex
was locked by the current thread.
Releases the lock. Raises ThreadError
if mutex
wasn’t locked by the current thread.
Obtains a lock, runs the block, and releases the lock when the block completes. See the example under Thread::Mutex
.
Wakes up all threads waiting for this lock.
Prettify (indent) an HTML string.
string
is the HTML string to indent. shift
is the indentation unit to use; it defaults to two spaces.
print CGI.pretty("<HTML><BODY></BODY></HTML>") # <HTML> # <BODY> # </BODY> # </HTML> print CGI.pretty("<HTML><BODY></BODY></HTML>", "\t") # <HTML> # <BODY> # </BODY> # </HTML>
Formats and writes to the stream converting parameters under control of the format string.
See Kernel#sprintf
for format string details.
Generate a BlockQuote element as a string.
cite
can either be a string, give the URI
for the source of the quoted text, or a hash, giving all attributes of the element, or it can be omitted, in which case the element has no attributes.
The body is provided by the passed-in no-argument block
blockquote("http://www.example.com/quotes/foo.html") { "Foo!" } #=> "<BLOCKQUOTE CITE=\"http://www.example.com/quotes/foo.html\">Foo!</BLOCKQUOTE>
