Hi all,
I am looking for a function that gives me a lazy sequence from a
simple key, value file. Keys are words at the beginning of a line.
Value start after a key and can span multiple lines. Thus, a file
looks something like:
key1 = value1 is there
and continues
key2 = new value
key3 = value3
takes some more lines
as well
I have a simple python generator that does the dirty work for me:
def readpairs(name):
key = None
value = None
for line in file(name):
line = line.strip()
data = line.split("=")
if len(data) == 2:
if key is not None:
yield key, value
key, value = data[0], [data[1]]
else:
if key is None:
raise Exception("no key here")
value.append(line)
if key is not None:
yield key, value
The nice thing about this code is that it hides the messy details of
reading multiple lines and gives me a clean sequence of key, value
pairs to work with. I would like to have the same thing in clojure. I
just do not find a good solution. Do you have any idea?
Thanks a lot.
Ulrich
