Sublime Text 2 New Window (via AppleScript)

Building upon my older post on opening new window in Text Mate 2, I now threw together small script to do the same in Sublime Text 2.

While Sublime Text 2 is superb text editor, it is not Mac native, thus it’s even less probable that a new Mac-style Dock icon menu will appear in near future, that allows opening new window quickly. Thus a helper application is in order.

Based on the original TMNewWindow code, only small modifications were needed. One unexpected behavior was with detecting working state of the application. For whatever reason the original script gave errors when run against Sublime Text 2.

Again, the AppleScript application is linked below and feel free to send me updates and patches if needed.

 

 

uses of Ruby’s Object#tap

Ruby 1.9’s Object#tap method has always seemed useful to me, but until now I hadn’t met the chance to use it. Every other time it seemed like abusing it in some way.

Now I came to an old code. Consider this:

cgi.text_field( "name" => "myfield",
                "value" => value,
                "size" => 20,
                "maxlength" => maxlength
              )

I needed to turn that maxlength into a conditional attribute (omiting it if it’s nil).
One way would have been extracting the attributes into a separate variable:

attrs = {
          "name" => "myfield",
          "value" => value,
          "size" => 20
        }
attrs['maxlength'] = maxlength if maxlength
cgi.text_field( attrs )

But this separates visually the cgi.text_field() call from it’s arguments, which I don’t like. Tap to the resque:

cgi.text_field({  "name" => "myfield",
                  "value" => value,
                  "size" => 20
                }.tap{|attrs| 
                  attrs['maxlength'] = maxlength if maxlength
                })

Now, isn’t that nice! (OK, maybe it isn’t, but at least it is encompassed in the method call and makes it easy to spot all attributes).
