Komodo line selection macro

I was recently asked if it was possible to turn a partial text selection inside the Komodo editor into a full line selection (similar to the way Vi's visual line selection works "Shift-V").

Indeed it is possible, though you'll need a Komodo macro to perform the functionality. Here is the Komodo JavaScript macro I came up with after a couple of minutes:

var scimoz = ko.views.manager.currentView.scimoz;
if(scimoz){
var anchorPos = scimoz.anchor;
var currentPos = scimoz.currentPos;
// Line start/end positions will depend upon where the cursor is.
if(anchorPos < currentPos){

        scimoz.anchor = scimoz.positionFromLine(scimoz.lineFromPosition(anchorPos));

        scimoz.currentPos = Math.max(scimoz.getLineEndPosition(scimoz.lineFromPosition(currentPos)),

                                     scimoz.positionFromLine(scimoz.lineFromPosition(currentPos)+1));
}else{

        scimoz.currentPos = scimoz.positionFromLine(scimoz.lineFromPosition(currentPos));

        scimoz.anchor = Math.max(scimoz.getLineEndPosition(scimoz.lineFromPosition(anchorPos)),

                                 scimoz.positionFromLine(scimoz.lineFromPosition(anchorPos)+1));
}
    // To make the copy operation right here as well, uncomment the below lines.
    //var clipHelper = Components.classes["@mozilla.org/widget/clipboardhelper;1"].getService(Components.interfaces.nsIClipboardHelper);

    //clipHelper.copyString(String(scimoz.selText));

}

var scimoz = ko.views.manager.currentView.scimoz;
if (scimoz) {
    var anchorPos = scimoz.anchor;
    var currentPos = scimoz.currentPos;
    // Line start/end positions will depend upon where the cursor is.
    if (anchorPos < currentPos) {
        scimoz.anchor = scimoz.positionFromLine(scimoz.lineFromPosition(anchorPos));
        scimoz.currentPos = Math.max(scimoz.getLineEndPosition(scimoz.lineFromPosition(currentPos)),
                                     scimoz.positionFromLine(scimoz.lineFromPosition(currentPos)+1));
    } else {
        scimoz.currentPos = scimoz.positionFromLine(scimoz.lineFromPosition(currentPos));
        scimoz.anchor = Math.max(scimoz.getLineEndPosition(scimoz.lineFromPosition(anchorPos)),
                                 scimoz.positionFromLine(scimoz.lineFromPosition(anchorPos)+1));
    }

    // To make the copy operation right here as well, uncomment the below lines.

    //var clipHelper = Components.classes["@mozilla.org/widget/clipboardhelper;1"].getService(Components.interfaces.nsIClipboardHelper);
    //clipHelper.copyString(String(scimoz.selText));
}

Create a new JavaScript macro in your Komodo toolbox, with the above contents. You can then also assign the macro a specific keybinding to make it trigger when you need it to.
