Takes source
, which can be a string of Ruby
code, or an open File
object. that contains Ruby
source code. It parses and compiles using prism.
Optionally takes file
, path
, and line
which describe the file path, real path and first line number of the ruby code in source
which are metadata attached to the returned iseq
.
file
is used for ‘__FILE__` and exception backtrace. path
is used for require_relative
base. It is recommended these should be the same full path.
options
, which can be true
, false
or a Hash
, is used to modify the default behavior of the Ruby
iseq compiler.
For details regarding valid compile options see ::compile_option=
.

Take a location from the prism parser and set the necessary instance variables.
Posts data to a host; returns a Net::HTTPResponse
object.
Argument url
must be a URI
; argument data
must be a hash:
_uri = uri.dup _uri.path = '/posts' data = {title: 'foo', body: 'bar', userId: 1} res = Net::HTTP.post_form(_uri, data) # => #<Net::HTTPCreated 201 Created readbody=true> puts res.body
Output:
{ "title": "foo", "body": "bar", "userId": "1", "id": 101 }
Sets the write timeout, in seconds, for self
to integer sec
; the initial value is 60.
Argument sec
must be a non-negative numeric value:
_uri = uri.dup _uri.path = '/posts' body = 'bar' * 200000 data = <<EOF {"title": "foo", "body": "#{body}", "userId": "1"} EOF headers = {'content-type': 'application/json'} http = Net::HTTP.new(hostname) http.write_timeout # => 60 http.post(_uri.path, data, headers) # => #<Net::HTTPCreated 201 Created readbody=true> http.write_timeout = 0 http.post(_uri.path, data, headers) # Raises Net::WriteTimeout.
Sets the continue timeout value, which is the number of seconds to wait for an expected 100 Continue response. If the HTTP object does not receive a response in this many seconds it sends the request body.
Sends a GET request to the server; forms the response into a Net::HTTPResponse
object.
The request is based on the Net::HTTP::Get
object created from string path
and initial headers hash initheader
.
With no block given, returns the response object:
http = Net::HTTP.new(hostname) http.request_get('/todos') # => #<Net::HTTPOK 200 OK readbody=true>
With a block given, calls the block with the response object and returns the response object:
http.request_get('/todos') do |res| p res end # => #<Net::HTTPOK 200 OK readbody=true>
Output:
#<Net::HTTPOK 200 OK readbody=false>
Sends a HEAD request to the server; returns an instance of a subclass of Net::HTTPResponse
.
The request is based on the Net::HTTP::Head
object created from string path
and initial headers hash initheader
.
http = Net::HTTP.new(hostname) http.head('/todos/1') # => #<Net::HTTPOK 200 OK readbody=true>
Sends an HTTP request to the server; returns an instance of a subclass of Net::HTTPResponse
.
The request is based on the Net::HTTPRequest
object created from string path
, string data
, and initial headers hash header
. That object is an instance of the subclass of Net::HTTPRequest, that corresponds to the given uppercase string name
, which must be an HTTP request method or a WebDAV request method.
Examples:
http = Net::HTTP.new(hostname) http.send_request('GET', '/todos/1') # => #<Net::HTTPOK 200 OK readbody=true> http.send_request('POST', '/todos', 'xyzzy') # => #<Net::HTTPCreated 201 Created readbody=true>
