Hi folks,
I've been having some difficulty coming up with a scheme for writing
to files in a thread-safe manner. The files are named with the hash of
their content, so they are effectively immutable.
The problem comes with writing them for the first time. I need to
ensure that while a file is in
Thank you so much. I'm confused, however, about what functions you're
allowed to call inside a macro outside of a quote. I read once that
"runtime information" was unavailable during the macro phase. But it
seems that one is still allowed to call array-map, apply, take-nth,
and vec during the macr
You can pretty much call anything outside of the quote, in fact all runtime
information is available (you have access to anything that was previously
read). The main thing to understand is that all parameters passed to your
macro are unevaluated.

So I've got a circular dependency problem. There's a few ways to move
functions and (require )s around but the problem remains -- these
three files fundamentally depend on one another:
parser.clj - lexer & parser (using joshua choi's excellent fnparse
library)
defaulttags.clj - multimethods
This worked for me.
I downloaded the svn and built it. Once I added the jar to my
classpath, I was good to go. I did this by modifying the clj script I
use.
Thanks!

Hello,
You could maybe solve the read problem by also embedding, in the name of the
file, its intended content size ?
So it could be reasonably cheap to check if a file is present but not yet
totally flushed to the disk by comparing its intended size (from its name)
and its current real size ?

Hello!
Function 'set' looses some of its data. It seems that there is a
problem with comparison between lists and vectors:
user=> (count [nil false true 0 42 0.0 3.14 2/3 0M 1M \c "" "abc"
'sym :kw () '(1 2) [] [1 2] {} {:a 1 :b 2} #{} #{1 2}])
23
user=> (set [nil false true 0 42 0.0 3.14 2/3 0M
Similar is:
user=> #{[] ()}
#{[]}
user=> #{[] [1 2]}
#{[] [1 2]}
user=> (hash-set [] ())
#{[]}
