Re: Improved Error Messages - Part XXXVIII

I think it's important that Clojure be good at exploring Java libraries. Helpful and correct error messages are important for this. I often go looking for a function at the REPL, like so: user=> substring java.lang.Exception: Unable to resolve symbol: substring in this context (NO_SOURCE_FILE:

Looking for the inverse of slurp

Has the inverse of slurp been added to the core libraries yet? Like this: (spit "Some text" "/foo.txt") to make a file called 'foo.txt' containing "Some text". By the way, it appears that Clojure (or Java) doesn't recognize ~, as in (slurp "~/foo.txt"). True? --~--~-~--~~

Re: learning clojure

For the File / IO things, skip the Java libs - they are pretty low level. Go with the Jakarta Commons libs: http://commons.apache.org/io/description.html , as Stuart has recommended elsewhere. On Mon, Nov 24, 2008 at 6:48 AM, Stuart Sierra <[EMAIL PROTECTED]> wrote: > > It's useful to know the s

Re: Poll: Which clojure.contrib libs should be bundled with Clojure?

Seconded. As far as I can tell all you can do is go to Sourceforge and poke around in the source code: http://clojure-contrib.svn.sourceforge.net/viewvc/clojure-contrib/trunk/src/clojure/contrib/ On Wed, Nov 26, 2008 at 12:26 AM, Ralf Bensmann <[EMAIL PROTECTED]> wrote: > ? > > On Mon, Nov 24, 2

Re: quit

It's very handy to be able to type in a symbol at the REPL and see its value. On Sun, Nov 30, 2008 at 10:15 AM, Mark Volkmann <[EMAIL PROTECTED]> wrote: > > On Sun, Nov 30, 2008 at 10:35 AM, Paul Barry <[EMAIL PROTECTED]> wrote: >> >> It's a minor thing, but wouldn't it be a good idea to put (de

Re: re-seq and other functions

Right, the outer parenthesis denote a list. That list contains only one element. The element is the vector ["qui" "ui" "i"] On Thu, Dec 11, 2008 at 9:43 PM, Stephen C. Gilardi wrote: > > In the latter case the result is a seq containing a single element: > the vector. There is nothing to sort/

Why aren't lists callable?

Why aren't all sequences callable, i.e. why don't they all implement IFn? I'd like to use lists like this sometimes. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Clojure" group. To post to this group, send email

Re: Why aren't lists callable?

Then why are sets callable? Not that I'm complaining - I found it handy, then came to wonder why lists aren't. -Ethan > I'd just like to add to this discussion that maps and vectors are > functions not just because it's neat or possible, with the > implementation one of many possibilities, but
