Hi Wush,
After some more cleanup and consolidation, the package is now down to this:
edd@max:~/git/rhiredis$ tree .

4 directories, 10 files
edd@max:~/git/rhiredis$
One C++ file declaring a simple class, and the Rcpp modules declaration, all
in about sixty lines -- see details at
https://github.com/eddelbuettel/rhiredis/blob/master/src/Redis.cpp
The R file is just one line ensuring the module gets loaded.
The demo/ script show how to use it:
edd@max:~/git/rhiredis$ cat demo/simpleRedisClient.R
#!/usr/bin/Rscript
suppressMessages(library(rhiredis))
print(Redis) # prints the Module's docstrings
redis <- new(Redis)
redis$exec("PING") # simple PING -> PONG test
redis$exec("PING")
redis2 <- new(Redis, "127.0.0.1", 6379) # create 2nd instance
redis2$exec("SET testchannel 42") # write some data
redis2$exec("GET testchannel") # retrieve
You can use any Redis command just by concatenating strings, that should also
work for serializing arbitrary R objects into (raw) strings and back. More
user-level work could be done here. My main focus was to provide the simple
C++ class wrapping everyhing --- without any explicit pointers, smart or
old-fashioned and not one new/delete.
The C++ file is simple too at just sixty line, see
Hope this helps, and thanks for suggesting the Redis wrapper via hiredis.
Hope this helps, Dirk
