Add the current {#possibility} to the dependency graph of the current {#state} @return [void]
Get all [gem, version] from the command line.
An argument in the form gem:ver is pull apart into the gen name and version, respectively.
Finds a spec and the source_uri it came from for gem gem_name
and version
. Returns an Array
of specs and sources required for installation of the gem.
In case we’re building docs in a background process, this method waits for that process to exit (or if it’s already been reaped, or never happened, swallows the Errno::ECHILD error).
Returns a new lazy enumerator with the concatenated results of running block
once for every element in the lazy enumerator.
["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force #=> ["f", "o", "o", "b", "a", "r"]
A value x
returned by block
is decomposed if either of the following conditions is true:
x
responds to both each and force, which means that x
is a lazy enumerator.
x
is an array or responds to to_ary.
Otherwise, x
is contained as-is in the return value.
[{a:1}, {b:2}].lazy.flat_map {|i| i}.force #=> [{:a=>1}, {:b=>2}]
If a block is given, iterates the given block for each element with an index, which starts from offset
, and returns a lazy enumerator that yields the same values (without the index).
If a block is not given, returns a new lazy enumerator that includes the index, starting from offset
.
offset
the starting index to use
Calls wait repeatedly while the given block yields a truthy value.
Tests bit bit in bn and returns true
if set, false
if not set.
Emit a scalar with value
and tag
This method is called when a parse error is found.
ERROR_TOKEN_ID is an internal ID of token which caused error. You can get string representation of this ID by calling token_to_str
.
ERROR_VALUE is a value of error token.
value_stack is a stack of symbol values. DO NOT MODIFY this object.
This method raises ParseError
by default.
If this method returns, parsers enter “error recovering mode”.
This method is called when some event handler is undefined. event
is :on_XXX, token
is the scanned token, and data
is a data accumulator.
The return value of this method is passed to the next event handler (as of Enumerable#inject
).
Same as IO
.
See Zlib::GzipReader
documentation for a description.
Returns true
if stat is writable by the real user id of this process.
File.stat("testfile").writable_real? #=> true
If stat is writable by others, returns an integer representing the file permission bits of stat. Returns nil
otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2)
.
m = File.stat("/tmp").world_writable? #=> 511 sprintf("%o", m) #=> "777"
Iterates over keys and objects in a weakly referenced object
