String interpolation not working for Ruby heredoc constant


const = <<-EOT.constantize


const = <<-EOT.gsub(/
/, '').constantize

This method that create string <<-EOF ... EOF put on the end of line, then constantize can't work properly. Removed undesired character , , s and all should work.

Look my test case:

conts = <<-EOF.constantize
=> ActionDispatch::Integration::Session
=> EOF

#> NameError: wrong constant name "Session

conts = <<-EOF.chomp.constantize
=> ActionDispatch::Integration::Session
=> EOF
#> ActionDispatch::Integration::Session

For many lines:

conts = <<-EOF
=> ActionDispatch::
=> Integration::
=> Session
=> EOF
=> "ActionDispatch::

Fix it:

conts = <<-EOF.gsub(/
/, '').constantize
=> ActionDispatch::
=> Integration::
=> Session
=> EOF
=> ActionDispatch::Integration::Session

Variable string concatenation and interpolation, string is stored in array
You are using single quotes, so no string interpolation is done, if you want strings interpolated you have to use double quotes"$var": $arr = array( 1,2,3); $i = 0; echo '$arr[0]'; // prints: $arr[0] <== Your error is here echo "$arr[0]"; // prints: 1 A better approach Anyways, you may like to do it this way: $array = array(12, 34); $s = implode("', '", $array); // $s is: 12', '34

Could someone describe a 2d interpolation method that is better than bilinear interpolation?
One widely-used interpolation method is kriging (or Gaussian process regression). However, the use of kriging is not advised when your data points are on a regular grid. The euclidian distances between data points are used to adjust the parameters of the model. But in a grid, there are much fewer values of distance than in, say, a randomly simulated set of points. Nevertheless, even if your da

Formatting dashes in string interpolation
With the version of string interpolation that's in VS 2015 Preview, you can use characters like dashes in the interpolation format by enclosing it in another pair of quotes: var dob2 = "Customer {customer.IdNo} was born on {customer.DateOfBirth : "yyyy-M-dd"}";

Heredoc for nested command in bash
You need to remove -c from your command line to make it accept heredoc: sshpass -p "vagrant" ssh vagrant@ "sudo bash <<EOF echo ls echo EOF" Also you may remove -i (interactive) option too. bash -c expects you to provide all commands on command line so this may work too: sshpass -p "vagrant" ssh vagrant@ "sudo bash -c 'echo; ls; echo'"

Dart constant time string comparison
The default implementation is not constant time, but you can just create your own comparison function that compares every code unit in the String and does not short circuit: bool secureCompare(String a, String b) { if(a.codeUnits.length != b.codeUnits.length) return false; var r = 0; for(int i = 0; i < a.codeUnits.length; i++) { r |= a.codeUnitAt(i) ^ b.codeUnitAt(i); } retu
