ANN: zip-visit and fast-zip-visit 1.0.2

The zip-visit library implements zipper-based visitors that allow one to carry and modify state during a depth first traversal of a zipper. There is an extensive description here: https://github.com/akhudek/zip-visit A short example of a zipper-based version of some. Here n is the node and s is

Re: how can I print the function name as parameter?

You need to pass not the function itself, but its Var. Because Vars are the ones that hold metadata. (show #'elementary/nothing-but-the-truth true) On Friday, May 2, 2014 4:28:49 AM UTC+2, Erlis Vidal wrote: > > Hi guys, > > I want to write a function (show) that will receive a function as > p

Re: What's clojure killer app? I don't see any.

The 'killer' problem domain for clojure is the same as that of any lisp: the creation of domain-specific languages. There exist a plethora of problems which are awkward to solve using conventional programming, and clojure's macros make it easier. An example is twitter's storm project. It's a real-

Re: ANN: om-sync

(Dave and I work together). I suspect it will be easy to come to a reasonable license. My own preferences would be EPL or MIT, and EPL only because it's common in the community. Beyond that, something like chord isn't actually the big problem in a scheme like this. The real issue is ensuring

Re: core.async over websocket + cljs + clojure

We've had something like this working for a while now, though our system uses browserchannel rather than websockets since we need to support older browsers. On the plus side, browserchannel handles some issues already such as managing the state of the connection to the server and retrying when i

Re: Extracting a database schema and using it to synthesize and check SQL queries at compile time

Hey Luc, Our use case is quite a bit different. We treat our database schema as part of our applications data model. In contrast, it seems that your problem is one of data integration. That's a much more difficult problem to solve. If I understand correctly, you have a code that generates a da

Re: Extracting a database schema and using it to synthesize and check SQL queries at compile time

This looks interesting. Hopefully it's a more consistent interface than information_schema. I'll try it out, thanks! On Wednesday, January 8, 2014 3:32:49 AM UTC-5, Shantanu Kumar wrote: > > >> The approach to read the database to generate code is pretty interesting. >> There is a more portable

Extracting a database schema and using it to synthesize and check SQL queries at compile time

Hey everyone, We've been exploring ways to make working with database code more efficient and less error prone. For complex queries, we prefer working directly with SQL. However, like for many others, a lot of our queries are very simple and repetitive. For example, retrieving or updating sing

Re: Is Clojure right for me?

You can define vars to be private to a namespace in clojure, thus preventing (1). In practice, I've found that (2) never comes up. Ultimately, you won't truly appreciate what is being said in this conversation without giving it a chance and trying it out. On Thursday, December 26, 2013 4:02:49

Re: Advice on choosing the right data structure

Additionally, if you need more complex access patterns you could see if this helps: https://github.com/akhudek/zip-visit For performance, there is a fast-zip library that is api compatible with clojure.zip. You can just swap the clojure.zip namespace for the fast-zip namespace. Note that you'd
