Hello,
I am using StringTemplate with Clojure here and I have this issue with
setting the template path for StringTemplate.
I don't want to hard code the absolute path in the code, and thus I have
used a relative path for the template directory.
But every time I have to cd (I use SLIME) to the r
Hi All,
Thanks for the great replies. John, the self-send-off idea is terrific and
hadn't occurred to me. I'll be using a variant of what you proposed.

That's because (binding) only works with a var that already exists, it
doesn't create a new one. To create your own var (instead of abusing a
clojure core one) just use "with-local-vars" instead o

How about borrowing a page from LaTeX? That has a \verb+text+ which can use
any desired delimiter character. My thought is to have something like
$+.+ turning whatever was between the character following $ (here, +)
until the next occurrence of that character into a literal string. A way to

No, maps don't support duplicate keys. What you're seeing is due to
an implementation detail in how array-maps are created from literals.

Hi people!
I just discovered that maps support duplicated keys:
user=> {:a 1 :b 2 :a 3}
{:a 1, :b 2, :a 3}
It was not clear to me, from documentation. I presumed that maps are like
dictionaries.
What is the rationale behind this behaviour?
Is it this feature used in some way by clojure library?
{"quoted" text} is also a map, so conflicts with existing syntax.

I always find map transformations easier to write with reduce:
(defn transform-map [f mm]
(reduce (fn [m [k v]] (assoc m k (f v))) {} mm))

Sure, heredoc could be done, it has the nice advantage of being

The former is used for short strings, often for the purpose of regular

What if you need to use braces? It seems to me that any syntax for
representing long strings needs a terminator that is unlikely to occur
within the string itself. For example, Python uses """, and XML CDATA
uses ]]>, both of which are character sequences unlikely to turn up in
a string. By contra

My approach (which I might upload once I've tidied it up a bit) was to
use a hash-map of [x y] cell coordinates to a set of all remaining
numbers. So, something like:
{[0 0] #{1 2 3 4} [0 1] #{5 6 7 8} …}
Then I just made some functions that mapped an [x y] pair to all it's

It is. The question was about licensing issues when building GPLed

It's attempting to attach the metadata to the next following expression. In

operations in case that's useful. These operations return a new data
