I have a computationally expensive task in perl, and would like to inform the user that computation is ongoing by printing out a period after each portion of the computation is completed. Unfortunately, until I print a "\n", none of my periods are printed. How can I address this? ...
I am looking for the best br2nl function. I would like to replace all instances of <br> and <br /> with newlines \n. Much like the nl2br function but the opposite.

I'm currently working on a project where we'd like to allow a user to export their data to CSV. Some of the data we present has multiple values for a single cell, and so we use the standard CSV method of putting each value on its own line: Column A, Column B, Column C Value A, "Value B1 Value B2", Value C Most of the time this works f...

Hi all, One of our projects still uses CVS. Recently (sometime in the past year) the Cygwin cvs client (currently using 1.12.13) has given me problems when I update. I suspect the problem stems from windows/unix newline differences. It worked for years without a problem. Here are the symptoms. When I update from the command line, I ...

But it is writing out the tag as - <Tag> </Tag> i.e. with a newline character between the tags. The web service reading t...
I am trying to store a multiple line e-mail in an ini file using PHP/Zend Framework. My string has new lines characters in it, and when I use Zend_Config_Ini to parse the ini file, the new line characters come back escaped, so they are printed out on screen, instead of a line feed. Example: // ini file message = Hi {0},\n\nThis is a te...
First off, I'm a complete beginner at C++. I'm coding something using an API, and would like to pass text containing new lines to it, and have it print out the new lines at the other end. If I hardcode whatever I want it to print out, like so printInApp("Hello\nWorld"); it does come out as separate lines in the other end, but if I r...

Another noob regex problem/question. I'm probably doing something silly so I thought I'd exploit the general ingenuity of the SO regulars ;) Trying to match newlines but only if they occur within either double quotes or single quotes. I also want to catch strings that are between quotes but contain no newlines. Okay so there's what i g...

Is there a best practice for preventing mixed eol-styles in a subversion repository. I know that svn:eol-style=native can be set as an auto-prop, but I would have to ensure that it was set for all committers. I'm also reluctant to do a retrospective, repository-wide change of svn:eol-style if there is a less invasive solution. ...
