Hi, Nathan Would you like to describe shortly, why one would need such transformation. What are the benefits and what prevents to write code in CPS style by hand? p.s. sorry, I'm far from being expert in this field :) четверг, 19 февраля 2015 г., 23:45:10 UTC+6 пользователь Nathan Davis написал

Current best-of-breed JDBC libraries?

We tried Korma but found it too limiting for our needs. Later, I saw this tweet: https://twitter.com/ibdknox/status/557236505639665664 We are currently using HoneySQL to generate SQL which then gets passed to clojure.java.jdbc. e ​ On Tue, Feb 24, 2015 at 9:04 AM, Colin Yates wrote: > Hi all,

Sure, you can write code in CPS style by hand. Javascript developers do it all the time. But it's a very tedius, mechanical transformation. And tedius, mechanical transformations are what Lisps excel at ;-) We could also ask why we would want (reified) continuations? From a theoretical point o

Honeysql has to be one of the best examples of data transformation where Clojure really shines. {domain-data} -> {honey-sql data} -> SQL. Love it. I understand YeSQL's sweet spot is where the SQL is static except for parameters so yeah, not applicable for building up queries at runtime. Still, if

There's one important case where (coll n) is not the same as (get coll n) - when coll is nil. In that case (get coll n) will return nil and (coll n) will barf. I tend to use get in those cases because of this. On 24 February 2015 at 08:50, Colin Yates wrote: > A minor point (get col n) is the sa

It’s probably fine to do a linear search with .indexOf for small vectors, but I’ll just say as a matter of style I prefer to use a couple of maps to hold previous and next items. The maps are callable like functions, which I think reads very nicely. Using your example data for ranks: ;; helpe
