Results for: "slice"

Splits a string into an array of tokens in the same way the UNIX Bourne shell does.

argv = Shellwords.split('here are "two words"')
argv #=> ["here", "are", "two words"]

line must not contain NUL characters because of nature of exec system call.

Note, however, that this is not a command line parser. Shell metacharacters except for the single and double quotes and backslash are not treated as such.

argv = Shellwords.split('ruby my_prog.rb | less')
argv #=> ["ruby", "my_prog.rb", "|", "less"]

String#shellsplit is a shortcut for this function.

argv = 'here are "two words"'.shellsplit
argv #=> ["here", "are", "two words"]

SyntaxSuggest.valid? [Private]

Returns truthy if a given input source is valid syntax

SyntaxSuggest.valid?(<<~EOM) # => true
  def foo
  end
EOM

SyntaxSuggest.valid?(<<~EOM) # => false
  def foo
    def bar # Syntax error here
  end
EOM

You can also pass in an array of lines and they’ll be joined before evaluating

SyntaxSuggest.valid?(
  [
    "def foo\n",
    "end\n"
  ]
) # => true

SyntaxSuggest.valid?(
  [
    "def foo\n",
    "  def bar\n", # Syntax error here
    "end\n"
  ]
) # => false

As an FYI the CodeLine class instances respond to ‘to_s` so passing a CodeLine in as an object or as an array will convert it to it’s code representation.

Returns a 2-element array of the current (soft) limit and maximum (hard) limit for the given resource.

Argument resource specifies the resource whose limits are to be returned; see Process.setrlimit.

Each of the returned values cur_limit and max_limit is an integer; see Process.setrlimit.

Example:

Process.getrlimit(:CORE) # => [0, 18446744073709551615]

See Process.setrlimit.

Not available on all platforms.

Sets limits for the current process for the given resource to cur_limit (soft limit) and max_limit (hard limit); returns nil.

Argument resource specifies the resource whose limits are to be set; the argument may be given as a symbol, as a string, or as a constant beginning with Process::RLIMIT_ (e.g., :CORE, 'CORE', or Process::RLIMIT_CORE.

The resources available and supported are system-dependent, and may include (here expressed as symbols):

Arguments cur_limit and max_limit may be:

This example raises the soft limit of core size to the hard limit to try to make core dump possible:

Process.setrlimit(:CORE, Process.getrlimit(:CORE)[1])

Returns a list of signal names mapped to the corresponding underlying signal numbers.

Signal.list   #=> {"EXIT"=>0, "HUP"=>1, "INT"=>2, "QUIT"=>3, "ILL"=>4, "TRAP"=>5, "IOT"=>6, "ABRT"=>6, "FPE"=>8, "KILL"=>9, "BUS"=>7, "SEGV"=>11, "SYS"=>31, "PIPE"=>13, "ALRM"=>14, "TERM"=>15, "URG"=>23, "STOP"=>19, "TSTP"=>20, "CONT"=>18, "CHLD"=>17, "CLD"=>17, "TTIN"=>21, "TTOU"=>22, "IO"=>29, "XCPU"=>24, "XFSZ"=>25, "VTALRM"=>26, "PROF"=>27, "WINCH"=>28, "USR1"=>10, "USR2"=>12, "PWR"=>30, "POLL"=>29}

Scanning is intentionally conservative because we have no way of rolling back an aggressive block (at this time)

If a block was stopped for some trivial reason, (like an empty line) but the next line would have caused it to be balanced then we can check that condition and grab just one more line either up or down.

For example, below if we’re scanning up, line 2 might cause the scanning to stop. This is because empty lines might denote logical breaks where the user intended to chunk code which is a good place to stop and check validity. Unfortunately it also means we might have a “dangling” keyword or end.

1 def bark
2
3 end

If lines 2 and 3 are in the block, then when this method is run it would see it is unbalanced, but that acquiring line 1 would make it balanced, so that’s what it does.

Serializes the public key to DER-encoded X.509 SubjectPublicKeyInfo format.

Serializes the public key to PEM-encoded X.509 SubjectPublicKeyInfo format.

A PEM-encoded key will look like:

-----BEGIN PUBLIC KEY-----
[...]
-----END PUBLIC KEY-----

Expands lazy enumerator to an array. See Enumerable#to_a.

No documentation available

Indicated whether this Cipher instance uses an Authenticated Encryption mode.

Called when an alias is found to anchor. anchor will be the name of the anchor found.

Example

Here we have an example of an array that references itself in YAML:

--- &ponies
- first element
- *ponies

&ponies is the anchor, *ponies is the alias. In this case, alias is called with “ponies”.

No documentation available

Emit an alias with anchor.

See Psych::Handler#alias

Get the output style, canonical or not.

Set the output style to canonical, or not.

The line number of the current token. This value starts from 1. This method is valid only in event handlers.
