Removing Preformatted Word Wrapping

abitkin has asked for the wisdom of the Perl Monks concerning the following question:

Okay, I'm posting this without working on it myself yet. It mainly is a challenge for those who have time to work on it now, and I'll hack away at it after work. (In about 7 hours or so.)

So the idea is this, I use fortune for a number of things; however there is an annoyance. The people who wrote the fortunes put newlines in for wrapping and such. Normally this wouldn't be a problem, if I was using fortune in a terminal, but in this case, it's a resizable window. So newlines within a quote should be removed, but others should stay.

So, to make this easier to explain I ran my fortune command a number of times and seperated the quotes by a line of "=". I then made a copy of it and corrected it by hand. The goal is to have a perl script do it for me.

Something to remember, not only spaces are used, but also tabs, so be aware of that.

There are really only a couple of tasks here:

figure out if the line break at the end of the current line is there for wrapping
If it is, make sure by removing it, there still is a space in between words
Clean up any tabs or other whitespace from the start of the line added by removing the newline

I see at least three conditions for wrapping: `Name: bla bla bla bla -> Name: bla bla bla bla -- bla bla bla bla -> -- bla bla bla bla bla bla bla bla -> bla bla bla bla` [download] That's it for now; I must be off.	[reply] [d/l]

Clap clap That is worth applauding. My line of thinking was to check if the newline was a result of the next word being of a length that would cause a wrap. I have to say this is impressive, aligning and everything. Definite ++. == Kwyjibo. A big, dumb, balding North American ape. With no chin.	[reply]
