Scala - Get files based on name pattern -


i filter files based on patterns :

 - team_*.txt (e.g.: team_orlando.txt);  - name.*.city.txt (e.g.: name.robert.california.txt);

or name (the pattern * . * - has spaces because broken text).

all filters come database table , dynamic.

i'm trying avoid use commands cp or mv. possible filter files using patterns above ?

here i've tried got regex error:

  def getfiles(dir:file, filter:string) = {                                                (dir.isdirectory, dir.exists) match {                                                    case (true, true) =>                                                                     dir.listfiles.filter(f => f.getname.matches(filter))                                 case _ =>                                                                                array[file]()                                                                      }                                                                                    }

you can use java.nio files.newdirectorystream() that, accept pattern in desired format:

val stream = files.newdirectorystream(dir, pattern)

check http://docs.oracle.com/javase/tutorial/essential/io/dirs.html#glob detailed description.

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
