[Sc-devel] getting line in textView/Document

[Andrea Valle <valle@xxxxxxxxxxx>]

Hi to all,

In need to get a line from a multiline textview and a Document I wrote this little methods.

Sorry if maybe the same thing can already been done.

In negative case, I find them useful.

Code surely can be cleaned up.

As far as I tested they work fine.

// easier to grab the line where the cursor is placed

+ JSCTextView {

getLine { 

var lineSize = 0, index = 0, actualLine ;

var lineArr = this.string.split($\n) ;

var incrementArr = lineArr.collect({|l| lineSize = lineSize+l.size+1}) ;

while ({ incrementArr[index] <= this.selectionStart },

{ index = index + 1 }) ;

^actualLine = lineArr[index] ;

}

}

+ SCTextView {

getLine { 

var lineSize = 0, index = 0, actualLine ;

var lineArr = this.string.split($\n) ;

var incrementArr = lineArr.collect({|l| lineSize = lineSize+l.size+1}) ;

while ({ incrementArr[index] <= this.selectionStart },

{ index = index + 1 }) ;

^actualLine = lineArr[index] ;

}

+ Document {

getLine { 

var lineSize = 0, index = 0, actualLine ;

var lineArr = this.string.split($\n) ;

var incrementArr = lineArr.collect({|l| lineSize = lineSize+l.size+1}) ;

while ({ incrementArr[index] <= this.selectionStart },

{ index = index + 1 }) ;

^actualLine = lineArr[index] ;

}

}

I did this interview where I just mentioned that I read Foucault. Who doesn't in university, right? I was in this strip club giving this guy a lap dance and all he wanted to do was to discuss Foucault with me. Well, I can stand naked and do my little dance, or I can discuss Foucault, but not at the same time; too much information.
