Returns the one-character string which cause Encoding::UndefinedConversionError
.
ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP") begin ec.convert("\xa0") rescue Encoding::UndefinedConversionError puts $!.error_char.dump #=> "\xC2\xA0" p $!.error_char.encoding #=> #<Encoding:UTF-8> end
Returns a conversion path.
p Encoding::Converter.search_convpath("ISO-8859-1", "EUC-JP") #=> [[#<Encoding:ISO-8859-1>, #<Encoding:UTF-8>], # [#<Encoding:UTF-8>, #<Encoding:EUC-JP>]] p Encoding::Converter.search_convpath("ISO-8859-1", "EUC-JP", universal_newline: true) or p Encoding::Converter.search_convpath("ISO-8859-1", "EUC-JP", newline: :universal) #=> [[#<Encoding:ISO-8859-1>, #<Encoding:UTF-8>], # [#<Encoding:UTF-8>, #<Encoding:EUC-JP>], # "universal_newline"] p Encoding::Converter.search_convpath("ISO-8859-1", "UTF-32BE", universal_newline: true) or p Encoding::Converter.search_convpath("ISO-8859-1", "UTF-32BE", newline: :universal) #=> [[#<Encoding:ISO-8859-1>, #<Encoding:UTF-8>], # "universal_newline", # [#<Encoding:UTF-8>, #<Encoding:UTF-32BE>]]
Calls the given block once for each byte in the stream.
Generate a sequence of checkbox elements, as a String
.
The checkboxes will all have the same name
attribute. Each checkbox is followed by a label. There will be one checkbox for each value. Each value can be specified as a String
, which will be used both as the value of the VALUE attribute and as the label for that checkbox. A single-element array has the same effect.
Each value can also be specified as a three-element array. The first element is the VALUE attribute; the second is the label; and the third is a boolean specifying whether this checkbox is CHECKED.
Each value can also be specified as a two-element array, by omitting either the value element (defaults to the same as the label), or the boolean checked element (defaults to false).
checkbox_group("name", "foo", "bar", "baz") # <INPUT TYPE="checkbox" NAME="name" VALUE="foo">foo # <INPUT TYPE="checkbox" NAME="name" VALUE="bar">bar # <INPUT TYPE="checkbox" NAME="name" VALUE="baz">baz checkbox_group("name", ["foo"], ["bar", true], "baz") # <INPUT TYPE="checkbox" NAME="name" VALUE="foo">foo # <INPUT TYPE="checkbox" CHECKED NAME="name" VALUE="bar">bar # <INPUT TYPE="checkbox" NAME="name" VALUE="baz">baz checkbox_group("name", ["1", "Foo"], ["2", "Bar", true], "Baz") # <INPUT TYPE="checkbox" NAME="name" VALUE="1">Foo # <INPUT TYPE="checkbox" CHECKED NAME="name" VALUE="2">Bar # <INPUT TYPE="checkbox" NAME="name" VALUE="Baz">Baz checkbox_group("NAME" => "name", "VALUES" => ["foo", "bar", "baz"]) checkbox_group("NAME" => "name", "VALUES" => [["foo"], ["bar", true], "baz"]) checkbox_group("NAME" => "name", "VALUES" => [["1", "Foo"], ["2", "Bar", true], "Baz"])
Calls the block with each key/value pair:
res = Net::HTTP.get_response(hostname, '/todos/1') res.each_header do |key, value| p [key, value] if key.start_with?('c') end
Output:
["content-type", "application/json; charset=utf-8"] ["connection", "keep-alive"] ["cache-control", "max-age=43200"] ["cf-cache-status", "HIT"] ["cf-ray", "771d17e9bc542cf5-ORD"]
Returns an enumerator if no block is given.
Net::HTTPHeader#each
is an alias for Net::HTTPHeader#each_header
.
Calls the block with each field key:
res = Net::HTTP.get_response(hostname, '/todos/1') res.each_key do |key| p key if key.start_with?('c') end
Output:
"content-type" "connection" "cache-control" "cf-cache-status" "cf-ray"
Returns an enumerator if no block is given.
Net::HTTPHeader#each_name
is an alias for Net::HTTPHeader#each_key
.
Calls the block with each string field value:
res = Net::HTTP.get_response(hostname, '/todos/1') res.each_value do |value| p value if value.start_with?('c') end
Output:
"chunked" "cf-q-config;dur=6.0000002122251e-06" "cloudflare"
Returns an enumerator if no block is given.
