[TxMt] Re: Emulating keyboard activity with commands

[Steven Arnold]

Here is my hackish way of deleting a line from a file.  It seems like overkill.  Anyone got a better approach?

#!/usr/bin/env ruby -wKU
linenum = ENV['TM_LINE_NUMBER'].to_i
lines = STDIN.readlines
output = []
lines.each_with_index do |line, idx|
  if idx+1 != linenum
    output << line
  end
end
print output.join

You have to select the document as input, replace document as output, and use line interpolation as caret placement.  It only works if there is no selection.
