How to use counters in a redis key? -

is there way in redis ?

set counter 0 incr counter set key:{counter} "content of line 1" incr counter set key:{counter} "different content of line 2" 

my example code should substituted (i.e., transformed @ runtime redis-cli) into:

set counter 0 incr counter set key:1 "content of line 1" incr counter set key:2 "different content of line 2" etc. 

my problem not how auto-increment counter.
problem syntax: how include generic {wildcard} like:

set keyname:{currentcounter} "value" ... 

any appreciated. lot !

if using redis 2.6+ can use lua scripting along eval command following:

eval "local c = redis.call('incr', keys[1]);        return redis.call('set', keys[2] .. ':' .. c, argv[1])"       2 counter key "content of line 1" 

i broke onto multiple lines make easier read.

sorry, away on business few days. here sample showing works.

redis 127.0.0.1:6379> flushdb ok redis 127.0.0.1:6379> eval "local c = redis.call('incr', keys[1]); return redis.call('set', keys[2] .. ':' .. c, argv[1])" 2 counter key "content of line 1" ok redis 127.0.0.1:6379> keys * 1) "key:1" 2) "counter" redis 127.0.0.1:6379> counter "1" redis 127.0.0.1:6379> key:1 "content of line 1" redis 127.0.0.1:6379> eval "local c = redis.call('incr', keys[1]); return redis.call('set', keys[2] .. ':' .. c, argv[1])" 2 counter key "content of next thing" ok redis 127.0.0.1:6379> keys * 1) "key:1" 2) "key:2" 3) "counter" redis 127.0.0.1:6379> counter "2" redis 127.0.0.1:6379> key:2 "content of next thing"
