Okay, I was a little vague in my last post...the matrix is like a
Wheel of Fortune board and it knows nothing about newlines. After 24
characters it spills over onto the next line. Here is what I came up
with:
<pre>
## Wrap Text
def wrap_text(in_str, chars_line):
""" wrap text """
spaces = 0
new_str = ""
tmp_str = ""
while True:
tmp_str = in_str[:chars_line]
if tmp_str[chars_line-1].isspace():
new_str += tmp_str
else:
spaces = 0
for ch in reversed(tmp_str):
if ch.isspace():
break
spaces += 1
tmp_str = tmp_str[:chars_line-spaces]
tmp_str += " " * spaces
new_str += tmp_str
in_str = in_str[chars_line-spaces:]
if len(in_str) <= chars_line:
new_str += " " + in_str
break
return new_str
if __name__ == '__main__':
sample_text = """Personal firewall software may warn about the
connection IDLE makes to its subprocess using this computer's internal
loopback interface. This connection is not visible on any external
interface and no data is sent to or received from the Internet."""
print wrap_text(sample_text, 24)
</pre>
It doesn't even run but when I go through it interactively it seems
okay. Once again, any help is appreciated.
