Multiline Regular Expressions

There are a lot of text editors that offer regular expression search and replace, but rare are those that support multiline regular expressions. In my case I need to find all the function headers with starting body bracket.
example:
"int a(int b, int c)
{"

should be changed with
"int a(int b, int c)
{
printf("Entered function a");"

Text editor that supports such thing is called "EditPad Pro". Besides multiline regular expression support, it also have coloring system for your regular expression, so u can debug your regex easier.

To be edited with regular expressions that solved my problem

One of nicer looking timeline graphs for Latex is by using the chronology package This is the example: \usepackage{chronology} ... \begin{chronology}[5]{1983}{2010}{3ex}{\textwidth} \event{1984}{one} \event[1985]{1986}{two} \event{\decimaldate{25}{12}{2001}}{three} \end{chronology} source .

Exporting Skype Chat/Skype Contacts to csv file using the shell script and sqlite3 (usually already installed on mac)

Edit: a very first draft version of Skype Exporter have been made and released. https://github.com/renesto/SkypeExportSwift/releases check it, and report any issues to renesto-at-gmail.com I heard there are not so many nice ways to get the chat history from skype, so I came across a page of one guy who shows a way to open the sql chat history database and delete all conversations. I thought to make something more from that idea (as delete chat history is now one of the options in skype) Create a file exportFromSkype.sh place either this text: sqlite3 -batch "$HOME/Library/Application Support/Skype/$1/main.db" < <EOF .mode csv .output $2.csv select * from Messages where dialog_partner = '$2'; .output stdout .exit EOF now make the script executable by running chmod +x exportFromSkype.sh now, when you want to export some chat history from certain person, you can do it by: sh exportFromSkype.sh your_skype_name your_friends_skype_name and i

trim() not supported by IE7 and IE8

Funny fact, trim function is not supported by IE7 and IE8. Ok, it is supported, but through jQuery trim function. So, when you have something like this: jQuery(...).attr().trim() , this trim() function stops having any relation to jQuery, as the attr() would return String type, which method would be then trim(). Since IE7 and IE8 do not support trim() method within String type, you should use instead jQuery.trim(jQuery(...).attr()) or if you don't wanna use jQuery (whyyyy?), you can simply implement the trim function youself. if(typeof String.prototype.trim !== 'function') { String.prototype.trim = function() { return this.replace(/^\s+|\s+$/g, ''); } } http://www.blogger.com/img/blank.gif source 1 source 2
