I have always been curious how many lines of Apex code I have written. Is it a couple hundred (haha, ya right), several thousand, a gazillion million trillion? There was never really a good way to figure this out unless you pulled down all of the data and inspected it file by file. Lame.

Enter Spring 10 and the removal of limits on collection size. Dooo da doooooo (trumpet music)!!!!!!! The data to figure out the number of lines has always been available but it has been difficult to process. All apex class and trigger code is stored in two tables that can be accessed by SOQL. The first part is easy, simply query all of the data, and count the lines. Before Spring 10 there was no good way to count the lines. There is no apex method to count the number of string matches, ie: count number of ‘\n’ breaks. There is a split method that cuts up a string based on pattern matches. What we can do is populate a list of strings split by \n. This will create one entry in our list for each line. TADA! Before Spring 10 this would not have worked if a class had more than 1000 lines as a list could only hold 1000 elements.

Now I know lines of code is totally subjective. Some weirdos will write code like this, 7 lines:

public void doSomething()
{
	if(something)
	{
		//do awesomeness
	}
}

While the cool kids will do it like this, 5 lines:

public void doSomething(){
	if(something){
		//do awesomeness
	}
}

However your write code, the weirdo way or the cool kid way, it is just darn fun to see how many lines you have written.

Here is the code that will give you that answer. Simply copy and paste this to your system log and hit execute. Then dig through a giant debug log that is still horrible (rant on that later) for 3 simple debug lines.

13:35:17.470|USER_DEBUG|[14,1]|DEBUG|Apex Class lines: 21388
13:35:17.470|USER_DEBUG|[15,1]|DEBUG|Apex Trigger lines: 1425
13:35:17.470|USER_DEBUG|[16,1]|DEBUG|Apex Total lines: 22813

Integer classLines = 0;
Integer triggerLines = 0;
 
for(ApexClass a : [Select Body From ApexClass]){
	List<String> lines = a.Body.split('\n');
	classLines += lines.size();
}
 
for(ApexTrigger a : [Select Body From ApexTrigger]){
	List<String> lines = a.Body.split('\n');
	triggerLines += lines.size();
}
 
system.debug('Apex Class lines: ' + classLines);
system.debug('Apex Trigger lines: ' + triggerLines);
system.debug('Apex Total lines: ' + (classLines+ triggerLines));
