a bH@sRdZddlZddlmZdgZGdddeZGdddeZGdd d eZdS) a Helper for looping over sequences, particular in templates. Often in a loop in a template it's handy to know what's next up, previously up, if this is the first or last item in the sequence, etc. These can be awkward to manage in a normal Python loop, but using the looper you can get a better sense of the context. Use like:: >>> for loop, item in looper(['a', 'b', 'c']): ... print loop.number, item ... if not loop.last: ... print '---' 1 a --- 2 b --- 3 c N) basestring_looperc@s(eZdZdZddZddZddZdS) rz Helper for looping (particularly in templates) Use this like:: for loop, item in looper(seq): if loop.first: ... cCs ||_dSN)seqselfrrf/Users/vegardjervell/Documents/master/model/venv/lib/python3.9/site-packages/Cython/Tempita/_looper.py__init__&szlooper.__init__cCs t|jSr) looper_iterrrrrr __iter__)szlooper.__iter__cCsd|jj|jfS)Nz <%s for %r>) __class____name__rr rrr __repr__,s zlooper.__repr__N)r __module__ __qualname____doc__r r rrrrr rs c@s2eZdZddZddZddZejdkr.eZdS) r cCst||_d|_dSNr)listrposrrrr r 3s zlooper_iter.__init__cCs|Srrr rrr r 7szlooper_iter.__iter__cCs@|jt|jkrtt|j|j|j|jf}|jd7_|SN)rlenr StopIterationloop_pos)rresultrrr __next__:s zlooper_iter.__next__3N) rrrr r rsysversionnextrrrr r 1s  r c@seZdZddZddZddZeeZddZeeZd d ZeeZd d Z ee Z e j d krfe Z ddZ ee Z ddZeeZddZeeZddZeeZddZeeZddZeeZd!ddZd"ddZdd ZdS)#rcCs||_||_dSrrr)rrrrrr r Gszloop_pos.__init__cCsd|j|j|jfS)Nzr"r rrr rKszloop_pos.__repr__cCs|jSrrr rrr indexOszloop_pos.indexcCs |jdSrr#r rrr numberSszloop_pos.numbercCs |j|jSrr"r rrr itemWsz loop_pos.itemcCs,z|j|jdWSty&YdS0dSr)rr IndexErrorr rrr r[s zloop_pos.__next__rcCs|jdkrdS|j|jdS)Nrr)rrr rrr previouses zloop_pos.previouscCs |jd SNr#r rrr oddksz loop_pos.oddcCs |jdSr)r#r rrr evenosz loop_pos.evencCs |jdkSrr#r rrr firstsszloop_pos.firstcCs|jt|jdkSr)rrrr rrr lastwsz loop_pos.lastcCs t|jSr)rrr rrr length{szloop_pos.lengthNcCs|jr dS||j|j|S)a Returns true if this item is the start of a new group, where groups mean that some attribute has changed.
