[ANN] Stringer (v0.3.1) - fast string concatenation

2019-01-11 Thread Shantanu Kumar 
Hi,

I am pleased to announce Stringer, a library for fast string concatenation. 
Stringer is designed (with tradeoffs) to complement Clojure's string concat 
operations.

https://github.com/kumarshantanu/stringer


Stringer's API contains several macros (so they can not be used as 
functions) - notably `strcat` and `strfmt` that are used frequently. 
`strcat` is the Java equivalent of string concatenation + operator. In 
Java, when you write ("foo" + 42 + "bar") the Java compiler generates 
in-line bytecode using java.lang.StringBuilder to concatenate the tokens. 
`strfmt` expects the format string (with limited specifier support) to be a 
literal and applies string interpolation to generate the formatted string 
much faster than `clojure.core/format`. The perf benchmark code is included 
in the repo.

We have used Stringer in production for over 3 years at SAP Concur with 
only one issue noticed/fixed over 2 years ago. It is usually hard to 
troubleshoot and optimize the long tail of latency; however, using Stringer 
has led to overall perf improvements in several composite use cases.

Re: State of Clojure 2019 Survey!

2019-01-11 Thread Sean Corfield 
I'm only seeing this in the web version of Google Groups. This did not get 
delivered via email -- so I'm replying to ensure more people see it.

Alex, pretty much none of your posts to the group seem to come through in 
email, although your _replies_ do (as do other people's replies to your 
posts).
