Basically a wrapper for Process.spawn
that:
Creates a child process for each of the given cmds
by calling Process.spawn
.
Does not wait for child processes to exit.
With no block given, returns an array of the wait threads for all of the child processes.
Example:
wait_threads = Open3.pipeline_start('ls', 'grep R') # => [#<Process::Waiter:0x000055e8de9d2bb0 run>, #<Process::Waiter:0x000055e8de9d2890 run>] wait_threads.each do |wait_thread| wait_thread.join end
Output:
Rakefile README.md
With a block given, calls the block with an array of the wait processes:
Open3.pipeline_start('ls', 'grep R') do |wait_threads| wait_threads.each do |wait_thread| wait_thread.join end end
Output:
Rakefile README.md
Like Process.spawn
, this method has potential security vulnerabilities if called with untrusted input; see Command Injection.
If the first argument is a hash, it becomes leading argument env
in each call to Process.spawn
; see Execution Environment.
If the last argument is a hash, it becomes trailing argument options
in each call to Process.spawn
; see Execution Options.
Each remaining argument in cmds
is one of:
A command_line
: a string that begins with a shell reserved word or special built-in, or contains one or more metacharacters.
An exe_path
: the string path to an executable to be called.
An array containing a command_line
or an exe_path
, along with zero or more string arguments for the command.

Mirror the Prism.parse_success?
API by using the serialization API.
SyntaxSuggest.valid_without?
[Private]
This will tell you if the ‘code_lines` would be valid if you removed the `without_lines`. In short it’s a way to detect if we’ve found the lines with syntax errors in our document yet.
code_lines = [ CodeLine.new(line: "def foo\n", index: 0) CodeLine.new(line: " def bar\n", index: 1) CodeLine.new(line: "end\n", index: 2) ] SyntaxSuggest.valid_without?( without_lines: code_lines[1], code_lines: code_lines ) # => true SyntaxSuggest.valid?(code_lines) # => false
Returns the code fragment that corresponds to this AST.
Note that this is an API for ruby internal use, debugging, and research. Do not use this for any other purpose. The compatibility is not guaranteed.
Also note that this API may return an incomplete code fragment that does not parse; for example, a here document following an expression may be dropped.
Returns a copy of the current source string, that was used to construct this Parser
.
Waits for a SSL/TLS client to initiate a handshake.
The X509
certificate for this socket endpoint.
See TCPServer#listen
for details.
Works similar to TCPServer#accept
.
Returns all certificate IDs in this request.
Returns a BasicResponse
for this response
Returns the CertificateId
for which this SingleResponse
is.
If the timestamp token is valid then this field contains the same nonce that was passed to the timestamp server in the initial Request
.
Sets the nonce (number used once) that the server shall include in its response. If the nonce is set, the server must return the same nonce value in a valid Response
.
Returns the nonce (number used once) that the server shall include in its response.
