| 1981 The repeat variable | |
| 1982 ~~~~~~~~~~~~~~~~~~~ | |
| 1983 | |
| 1984 The repeat variable holds an entry for each active iteration. That is, if | |
| 1985 you have a ``tal:repeat="user db/users"`` command, then there will be a | |
| 1986 repeat variable entry called "user". This may be accessed as either:: | |
| 1987 | |
| 1988 repeat/user | |
| 1989 python:repeat['user'] | |
| 1990 | |
| 1991 The "user" entry has a number of methods available for information: | |
| 1992 | |
| 1993 =============== ========================================================= | |
| 1994 Method Description | |
| 1995 =============== ========================================================= | |
| 1996 first True if the current item is the first in the sequence. | |
| 1997 last True if the current item is the last in the sequence. | |
| 1998 even True if the current item is an even item in the sequence. | |
| 1999 odd True if the current item is an odd item in the sequence. | |
| 2000 number Current position in the sequence, starting from 1. | |
| 2001 letter Current position in the sequence as a letter, a through | |
| 2002 z, then aa through zz, and so on. | |
| 2003 Letter Same as letter(), except uppercase. | |
| 2004 roman Current position in the sequence as lowercase roman | |
