java - How to prvent Xtend templates from printing Variables during loop -

-

i using xtend templates write small program. try using if statement, every time execute it prints variable in console, dont want to.

  «if x==y»     jump value «database.get(2)»     «jump_var_letter = string.charat(1)»     «old_jump_ahd=database.get(2) »   «endif»

here database array of integers , string array of letters. here want print value found @ database.get(2) i.e 5. last 2 expressions befor endif meant assignning few values( need not printed)

 jump value 5

instead get

 jump value 5   d   5

could please tell me how stop printing other 2 values. thank in advance help..

after looking sometime on net found prevent printing of expreesions in between using block expressions , returning null expression. (although method not encouraged, found provides me result wanted). expression posted written as:

«if x==y»       jump value «database.get(2)»       «{jump_var_letter = string.charat(1); "" }»       «{old_jump_ahd=database.get(2); ""} » «endif»

this prints 

  jump value 5.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
