Reads a line from the stream which is separated by eol.
Raises EOFError if at end of file.
Reads a one-character string from the stream. Raises an EOFError at end of file.
Reads a DER or PEM encoded string from string or io and returns an instance of the appropriate PKey class.
_string+ is a DER- or PEM-encoded string containing an arbitrary private or public key.
io is an instance of IO containing a DER- or PEM-encoded arbitrary private or public key.
pwd is an optional password in case string or io is an encrypted PEM resource.
If a block is given, it prints out each of the elements encountered. Block parameters are (in that order):
depth: The recursion depth, plus one with each constructed value being encountered (Integer)
offset: Current byte offset (Integer)
header length: Combined length in bytes of the Tag and Length headers. (Integer)
length: The overall remaining length of the entire data (Integer)
constructed: Whether this value is constructed or not (Boolean)
tag_class: Current tag class (Symbol)
tag: The current tag number (Integer)
der = File.binread('asn1data.der') OpenSSL::ASN1.traverse(der) do | depth, offset, header_len, length, constructed, tag_class, tag| puts "Depth: #{depth} Offset: #{offset} Length: #{length}" puts "Header length: #{header_len} Tag: #{tag} Tag class: #{tag_class} Constructed: #{constructed}" end
Returns a profile data report such as:
GC 1 invokes.

1 0.012 159240 212940 10647 0.00000000000001530000
Writes the GC::Profiler.result to $stdout or the given IO object.
Escape only the tags of certain HTML elements in string.
Takes an element or elements or array of elements. Each element is specified by the name of the element, without angle brackets. This matches both the start and the end tag of that element. The attribute list of the open tag will also be escaped (for instance, the double-quotes surrounding attribute values).
print CGI.escapeElement('<BR><A HREF="url"></A>', "A", "IMG") # "<BR><A HREF="url"></A>" print CGI.escapeElement('<BR><A HREF="url"></A>', ["A", "IMG"]) # "<BR><A HREF="url"></A>"
Undo escaping such as that done by CGI.escapeElement()
print CGI.unescapeElement( CGI.escapeHTML('<BR><A HREF="url"></A>'), "A", "IMG") # "<BR><A HREF="url"></A>" print CGI.unescapeElement( CGI.escapeHTML('<BR><A HREF="url"></A>'), ["A", "IMG"]) # "<BR><A HREF="url"></A>"
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>
Generate a reset button Input element, as a String.
This resets the values on a form to their initial values. value is the text displayed on the button. name is the name of this button.
Alternatively, the attributes can be specified as a hash.
reset # <INPUT TYPE="reset"> reset("reset") # <INPUT TYPE="reset" VALUE="reset"> reset("VALUE" => "reset", "ID" => "foo") # <INPUT TYPE="reset" VALUE="reset" ID="foo">
Generate a TextArea element, as a String.
name is the name of the textarea. cols is the number of columns and rows is the number of rows in the display.
Alternatively, the attributes can be specified as a hash.
The body is provided by the passed-in no-argument block
textarea("name") # = textarea("NAME" => "name", "COLS" => 70, "ROWS" => 10) textarea("name", 40, 5) # = textarea("NAME" => "name", "COLS" => 40, "ROWS" => 5)
OpenURI::OpenRead#read([options]) reads a content referenced by self and returns the content as string. The string is extended with OpenURI::Meta. The argument options is same as OpenURI::OpenRead#open.

Resets the trust directory for verifying gems.
Simple deprecation method that deprecates name by wrapping it up in a dummy method. It warns on each call to the dummy method telling the user of repl (unless repl is :none) and the year/month that it is planned to go away.

Calls say with msg or the results of the block if really_verbose is true.
