Re: (resolve (symbol f)) works at the REPL but not in an uberjar

2017-10-13 Thread Isaac Tsang 
That because you REPL had set `*ns*`, when Clojure bootstrap from 
clojure.main, the *ns* bound to clojure.core

Re: (resolve (symbol f)) works at the REPL but not in an uberjar

2017-10-13 Thread Gary Verhaegen 
>From the description of your problem, it's not really clear to me why you
insist on using strings. Why not use the functions directly? Functions can
serve as keys in maps. Granted, it's a bit ugly to print. You could also
build a map of string to function yourself. Not sure what the performance
of that would be compared to going through resolve every time; I would bet
on "faster" but without much confidence.

 In an uberjar this does not work. I read somewhere that the runtime
 name-space is different than the REPL namespace and different from the
 namespace that exists while the compiler compiles the code.

 So how do I resolve the symbol correctly?

 I have functions that call a MySQL database, and each function is named
 after a database table. Most of the mechanics of the call are the same, the
 only thing different is the SQL. So I have functions such as "company" and
 "user" and "product". I also have a function called (select). I call select
 with one of the other functions, given as a string:

 (select "product")

 Inside of (select) I need to turn "product" into a resolved symbol that
 I can call.

 Afterwards, I store the results in a map in an atom. I want to use the
 database names as the keys. So "product" should be the key that holds the
 results of the function "product".

 But what I need to do to correctly resolve the string to a function?

Is there a way I can avoid hard-coding " "denormalize.pull-from-mysql"" ? I 
guess it doesn't matter, but it does seem a little inelegant.

Nevermind. I found that this works, though I think it is ugly and

 resolved-f (resolve (symbol (str "denormalize.pull-from-mysql/"

(resolve (symbol f)) works at the REPL but not in an uberjar

2017-10-12 Thread lawrence . krubner 
At the REPL, this works perfectly:

 > (defn get-users [] [:susan :kwan])

In an uberjar this does not work. I read somewhere that the runtime 
name-space is different than the REPL namespace and different from the 
namespace that exists while the compiler compiles the code. 

So how do I resolve the symbol correctly? 

I have functions that call a MySQL database, and each function is named 
after a database table. Most of the mechanics of the call are the same, the 
only thing different is the SQL. So I have functions such as "company" and 
"user" and "product". I also have a function called (select). I call select 
with one of the other functions, given as a string: 

(select "product")

Inside of (select) I need to turn "product" into a resolved symbol that I 
can call. 

Afterwards, I store the results in a map in an atom. I want to use the 
database names as the keys. So "product" should be the key that holds the 
results of the function "product". 

But what I need to do to correctly resolve the string to a function?
