Re: newbie Q: how to tweak file-seq (original: how to selectively iterate through a tree of directories) ?

Sorry, I meant :when, not :where. Though it won't change the problem. Here's the rub: first file-seq produces its whole seq, then for comes along and filters out some of it. So (ignoring lazyness) file-seq ha already traversed symbolic links (at least for folders) by the time for sees it. I fear

Roelof, Unless supplied with an initial value, reduce will use the first value from the collection you supply - every sequence which doesn't start with "1" will give you the wrong answer. Take care, Moe On Sat, Oct 3, 2015 at 9:40 PM, Roelof Wobben wrote: > Hello, > > I have to make a function

Re: 4clojure count problem

Reduce can take either two or three arguments; when it takes two arguments, it makes some assumptions about the argument that was left out. You're using reduce with two arguments, so you might want to rethink those assumptions. On Sat, Oct 3, 2015 at 2:19 PM Roelof Wobben wrote: > Hello, > > I h

4clojure count problem

Hello, I have to make a function which counts a collection without using count. So I came up with this : (fn [coll] (reduce (fn [counter _ ] (inc counter)) coll))) it works well with coll is [ 1 2 3] but it fails with "Hello World" How can I improve my code to work in both cases. Please

Re: newbie Q: how to tweak file-seq (original: how to selectively iterate through a tree of directories) ?

Re: macroexpand and syntax-quote

This is very much by design. Clojure is somewhere between Common Lisp and Scheme in terms of macro hygiene. Being compatible with Common Lisp is explicitly not a goal for Clojure. Watch out for similarly named functions with different behavior too. On Saturday, 3 October 2015, bentav wrote: > C

I'm on Windows at the moment, so I can't test, but I think you can filter on isFile: (for [file (file-seq dir) :where (.isFile file)] (.getName file)) should work, I think. On 3 October 2015 at 07:36, wrote: > Under linux, I have a tree of directories like this: > > /path/top > > /path

Interfaces like ISeq are internal details of Clojure's implementation. They're not part of the public API, so there is no guarantee that they won't change in future releases. –S On Thursday, October 1, 2015 at 4:59:12 AM UTC-4, crocket wrote: > > http://clojure.github.io/clojure/javadoc/ doesn

I always assumed it was because vectors have similar properties to the classic java.util.Vector: they’re variable-length, contain heterogenous objects accessible by integer index, and safe for concurrent access from multiple threads: http://docs.oracle.com/javase/7/docs/api/java/util/Vector.html e

Re: Help with macro.

Hi, the behavior you describe is not specific to macros, but is due to the use of aliases after: (require '[foo.bar :as b]) this will give you false: (= 'foo.bar/x (first '(b/x))) while this will give you true: (= 'foo.bar/x (first '(foo.bar/x))) one way to solve it, is comparing the resolved

For people with a C/Java-style background, array typically designates a contiguous piece of memory that has been allocated at once, is thus fixed-size, and can be accessed randomly (i.e. by index). Vectors are typically structures or objects at a higher level, that still present a random-access col
