How to replace characters in string Erlang?
erlang, regex
Solution
Your solution works, and if you are comfortable with it, you should keep it.
On my side I prefer list comprehension : `[case X of ${ -> $a; _ -> X end || X <- StringForOldSessionID ]`. (just because I don't have to check the function documentation :o)
Problem
I have this piece of code that gets sessionid, make it a string, and then create a set with key as e.g. `{{1401,873063,143916},<0.16443.0>}` in redis. I'm trying replace `{` characters in this session with letter "a". ``` OldSessionID= io_lib:format("~p",[OldSession#session.sid]), StringForOldSessionID = lists:flatten(OldSessionID), ejabberd_redis:cmd([["SADD", StringForSessionID, StringForUserInfo]]); ``` I've tried this: ``` re:replace(N,"{","a",[global,{return,list}]). ``` Is this a good way of doing this? I read that regexp in Erlang is not a advised way of doing things.
