For this reason, the logical line counts (LLOC, LLOC', LLOW, any metrics derived from these metrics) are not suitable for measuring fully line numbered code. You usually need to start with a big mess before deciding how best to organize it. It consists of one or more uninsulated electrical cables (commonly multiples of three for three-phase power) suspended by towers or poles.. Overview [Translations: Belarussian, Bulgarian, Russian, Serbo-Croatian, Slovakian Ukrainian] cloc counts blank lines, comment lines, and physical lines of source code in many programming languages.Given two versions of a code base, cloc can compute differences in blank, comment, and source lines. Generally, any method longer than ten lines should make you start asking questions. Move the commands that were already inside the function inside the loop instead-- In other words "wrap a loop around the existing lines of code that are inside the function. The following limits have been suggested for Java: Procedure LLOC <= 50 Most of your classes probably will have fewer than 200 lines, but I think having some large beefy classes is unavoidable. For classic VB, the LINES metric, along with every other line count, excludes the (invisible) class and form declaration lines at the start of .frm and .cls files. There are several ways to count the lines. It can be an interface class (class with one empty method, or a class with some Public variables). Here is our suggestion for classification of Visual Basic project sizes. There are two parts to this article you may find interesting. this forum made possible by our volunteer staff, including ... As Einstein supposedly said "Make is as simple as possible, but no simpler". Change in Project Analyzer v7.1: MCOMM and MCOMM% values reported by Project Analyzer v7.1 are not comparable to those reported by earlier versions. In VB.NET, comments starting with UPGRADE_ are not meaningful, they have been generated by the Upgrade Wizard and they should be removed eventually. These "codeless" procedures are not listed in Project Metrics, so they don't really count as an exception to the minimum rules above. We base our classification on the total number of physical lines, excluding control definitions, as this is the easiest way to measure code size. We suggest that MCOMM% be at least 20%. File LLOC <= 2000 That is the (declarations) section, Dim, Const and Type statements and the like. Line counts are notorious in that they can vary between programming languages and coding styles. A minimum useful procedure contains 3 lines of code. What is a logical line then? Counting Lines! Using many lines in a function or a file. It's not a code line (LLOC=0). Since a logical line can expand over several lines, the physical line count exaggerates code size. However having said that, I had to create this tool because I could not easily find anything else out there that would do what I was after. It answers the question ". When you delete features, LLOC should decrease. Similarly, when explaining your files to others, often you describe your program in chunks. A line with both code and commentation is counted in LLOC, not in LLOC'. In VB2008 and later, it is also possible to leave out the " _" sequence in certain cases. To be exact, a whitespace line can be continued with " _" too, even though though this is silly coding and rarely seen. A program with a higher LLOC almost certainly "does more" than a program with a lower LLOC. This type of a metric counts the lines but excludes empty lines and comments. MATLAB ® files often consist of many commands. Thus, newer MCOMM and MCOMM% values may be lower. If you ask Python programmers what they like most about Python, they will often cite its high readability. 19.2 When should you write a function?. However, code that is excluded by a False condition in an #if .. #then .. #elseif .. #else .. #end if block is not counted as code. Even though you can put several commands on one line if separated by a semicolon, these lines can often be hard to notice. Measurement methods. LLOC' does not include any end-of-line comments, only the full comment lines. As a special case, when there are no code lines, MCOMM% defined as zero. Save the file either in the current folder or in a folder on the MATLAB search path. A line of VB code is not the same as a line of C++ code. By comparison, the Microsoft Windows operating system has roughly 50 million lines of code. They are counted from logical lines, and they sum up to 100%. Where a statement or a comment is split over two or more physical lines, they count as a logical line. Slightly exceeding 16% should not be a big problem, but one should probably avoid too high values such as over 30%. It's a matter of coding style to define a maximum limit for LLOC. This is the oldest and most widely used size metric. There's a pathological case where LLOW differs from the number of physical blank lines. A whitespace line is either 1) an empty line, or 2) a line with nothing else than spaces, tabs or other whitespace characters. You can also have a minimum limit so as to avoid empty or nearly empty files. I know that seems obvious at first, but hear me out, as many refactorings, abstractions, ���cleaner��� code increases the LOC. Code Sections Divide Your File into Code Sections. The counting rules have been refined to exclude some comment types that are not meaningful. When you sum up all the logical lines of code, comment and whitespace, you get the total number of logical lines. That means spaces and tabulation don't affect the counting. A minimum useful file contains one line of code. How many lines of code should a java function have . Since most of the insulation is provided by the surrounding air, overhead power Many useful comparisons involve only the order of magnitude of lines of code in a project. The first is the DirectoryLineCounter. Some useful limits are: Physical line counts are quite easy: that's simply the regular lines count. You can use the whitespace percentage (LLOW%, see below) as an indication of if you have enough empty lines in your code. When you add features, LLOC increases. In a summary, LLOC counts all logical lines except the following: LLOC is a good measure of the size of your program. Not using white space to good effect in code. Gorla, Benander, and Benander: Debugging Effort Estimation Using Software Metrics. The Mistakes I Made As a Beginner Programmer | by Samer Buna | ��� Only source files are included in the line counts. It is a simple measure, easy to understand, and widely used. Naturally, the amount of commentation is not the only issue, it's also about what you write in the comments. And, developers work on other things than just producing more and more code, such as documentation, planning, testing etc. It is written entirely in Perl with no dependencies outside the standard ��� A regular class, on the other hand, should always have at least 3 lines. To make the procedure do any work, it should thus have at least 3 lines of code. You may wish to use two limits: a lower warning limit (such as 66) and a higher maximum limit (such as 200). All the comment metrics (LLOC', MCOMM and MCOMM%) are based on logical lines. Lines excluded by compiler conditional directives, LLOC'% measures the relative amount of comment lines. A source file is one that has source code in it. You should set your own target values for this metric based on what you feel is readable. LLOCt measures the lines in a call tree. Project Metrics defines the following comment metrics. Classes reaching 200 lines of code could almost certainly be refactored into smaller classes with more specific responsibilities, but a hard 200 line limit seems a bit low. In VB.NET, multiline comments are not possible. x = 10 while x > 0: print x x = x - 3 a) 3 b) 4 c) 5 ... To allow the programmer to write bad code, but have it still work. Since LLOC excludes empty and comment lines, the maximum acceptable LLOC is lower than the maximum LINES. Compared to Visual Basic, COBOL DATA DIVISION is roughly equivalent to data declarations in Visual Basic. That way when you read it again, the purpose of the function leaps right out at you, and most of the time you won't need to care about how the function fulfills its purpose - which is the body of the function. This type of function must be defined within a file, not at the command line. Compiler directives (#const, #if etc.) Class LLOC <= 1500 Exceptionally high LLOC' or MCOMM may indicate the presence of a large amount of commented-out code. As programming languages differ in their uses and power of expression, this classification may not be directly usable for other languages. Adding blank lines improves legibility up to a point. Greenhorn Posts: 1. posted 9 years ago. It should contain at least some code to be of any use. Especially when measuring programmers' performance the line counts aren't perfect. Also be careful when paying for delivered code lines, as there are many ways to bloat the figure. The source files may also include (invisible) Attribute statements containing various attributes for procedures and variables. A study by Gorla, Benander and Benander compared debug time against the amount of whitespace lines. Writing a multiline comment is not a good practice, since you can always write two comment lines separately. Students of the Code.org tutorials (Code Studio) have written 24,707,369,638 lines of code.Is this a lot? This means one comment for every 5 code lines. A significantly lower MCOMM or MCOMM% should not be interpreted as suddenly degraded quality in this case. If the procedure can be split, do it, but it can also be left alone if it works better as a long procedure. PEP 8 -- Style Guide for Python Code Basically: Blank Lines Separate top-level function and class definitions with two blank lines. A common problem in line counts is also that empty (or whitespace) lines, as well as comments, are included in the count. | Ars ��� I am writing some complex login in a java function and my calling function has gone up to 150 lines of java code. I have been reviewing a lot of code lately and the larger the added LOC are the more concerned I am about being able to fully understand and ��� Lines of code, or LOC, looks like a simple concept. IEEE Transactions on Software Engineering Vol. Each line ends with a line break, usually CR+LF. A comment in VB is a statement that starts with a apostrophe (') or the REM statement. Once the user selects a point that is within the chosen radius of the mystery point, the mystery circle should appear. The idea is to review the longish procedures in the middle range. Functions . In fact, it's not counted as whitespace or comment either. You have now created a function called sum.of.squares which requires two arguments and returns the sum of the squares of these arguments. My dream scenario is for all of my methods to have 4-5 lines at most. The more development I do the more I feel like increased Lines Of Code (LOC), nearly always results in increased bugs. The physical lines count (LINES) is a simple but not a perfect way to measure code size. In no case should LLINES exceed LINES. These three percentages measure the relative amount of code, comments and whitespace lines. One should use whitespace wisely to add readability to code. How many lines of code? One programmer may produce a large number of lines, while the other spends a long time and succeeds in squeezing the same function in a small space. Only if a procedure exceeds the maximum limit should it be split in any case. ... A feature should have only one place in the code that handles it. The amount of whitespace is a matter of programming style. Which measure to use depends on what you intend to do. An empty line or a comment line is not counted in LLOC. LLOW is almost exactly the same as "the number of blank lines", or Physical Lines of Whitespace. With improper line counts, you can appear really productive by hitting the Enter key, or alternatively, pretend that you are writing tighter code by deleting all comments. If you have to spend effort into looking at a fragment of code to figure out what it's doing, then you should extract it into a function and name the function after that ���what���. Thus, all executable lines, as well as declarative lines, are counted in LLOC. On the other hand, if your code is simple, uses consistent naming and is easy to read, you can probably do with less comments. In classic VB, you could (in theory) write a multiline comment using the line continuation character "_". Programs with fewer or more blanks required more debug time. MCOMM counts only meaningful comments and ignores meaningless comments. What is more, it also counts as a meaningful comment. Class LLOC >= 3 To make the procedure do any work, it should thus have at least 3 lines of code. These statements are counted as code if they exist among your code. Here are the minimum limits: Procedure LLOC >= 3 Continuation lines should align wrapped elements either vertically using Python's implicit line joining inside parentheses, ... Code should be written in a way that does not disadvantage other implementations of Python ... function annotations in Python 3 code should ��� Code Style¶. Comments consisting of a single repeated letter are taken as banners and not counted in MCOMM. What is more, it is a good estimate of the complexity of a single file, class or procedure. Read more, ©Aivosto Oy - Project Analyzer Help Contents, http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=44385. Exception. you say in amazement as you stagger back trying to regain your balance. Most programming languages provide many built in functions that would otherwise require many steps to accomplish, for example computing the square root of a number. Exception. What function should be used in the blank to capitalize the first letter of the word stored in word? What does it do? This way your code will move the turtle randomly and call drawBubble many times. Do you mean using white-space between statements? Function Comments: Every function (in both the .h and the .c files) should have a comment describing: what function does; what its parameter values are what values it returns (if a function returns one type of value usually, and another value to indicate an error, your comment should describe both of these types of return values). Some problems are easier to solve with a long procedure instead of several shorter procedures. Indeed, a high level of readability is at the heart of the design of the Python language, following the recognized fact that code is read much more often than it is written. Often, you store a function in its own file. All programs should be commented in such a manner as to easily describe (in English) the purpose of the code and any algorithms used to accomplish the purpose. Google Is 2 Billion Lines of Code���And It's All in One Place | WIRED One or more statements followed by an end-of-line comment is a line of code. Any function that has more than 10 lines is just too long. current ranch time (not your local time) is, How many lines of code should a java function have, Returning error code from jar application, how to call matlab function from a java program, How to get random dropdownlist javascript value at the server site. To prevent adverse effects on metrics, old code should be either deleted or excluded using conditional compilation: Since excluded lines are not counted in LLOC, LLOC', LLOW or MCOMM, they don't affect these metrics in any way. A logical line is a logical line of code if has any other content than just a comment or whitespace. The "Supported as" column shows which metrics Project Metrics supports. you now have three copies of the same code). This is sometimes referred to as the. Old code that has been commented out counts as comment. It's usual that LLINES is somewhat less than LINES. Visual Basic programs typically contain one statement per line of code. The study was performed on COBOL. It can be difficult to achieve that when you're writing a new method. It's not a part of your program in the analyzed configuration, so it doesn't really have any meaning. In Visual Basic one splits a logical line using the " _" line continuation sequence. Source: Checkstyle utility for Java. Implementing a feature in VB6 may require more effort (or maybe less) than what it would take in VB.NET. If you use comment templates with information on copyright, developer, last modified date and other non-technical information, you should require a high MCOMM%, since the comments should also describe the code, not just the development process. In classic VB, an interface class can have empty methods containing just 2 lines of code. In this study the optimal amount of blanks was 14% to 20% in DATA DIVISION code and 8% to 16% in PROCEDURE DIVISION code. File LLOC >= 1. In classic VB, an interface class can have empty methods containing just 2 lines of code. This is the simplest line count. Some simple line count utilities may count the invisible declarative code at the start of .frm and .cls files. The line can be a constant or a global variable declaration, for example. A logical line of code is one that contains actual source code. A procedure, class or file should not be empty. One should not use such a utility to measure the code size of classic VB projects. MCOMM% measures how many meaningful comments there are per each logical line of code. A meaningful comment is a comment with textual content, even if as short as three consequtive characters. The interface has exactly one method, Countable::count(), which returns the return value for the count() function. Thus if you bear with me, you might find this code useful to you. Not putting blank lines between sections of code can also make it harder to read. Pick your preference. Functions ��� reusable blocks of code - Learn web development | ��� It is included in physical line count (LINES), though. For example, take a look at this code. Alternatively, it can represent a user-defined data type (class containing some Public variables). This is not a line count, but a statement count. A method contains too many lines of code. In that case, the best practice is to use the same name for the function and the file (in this example, fact.m), since MATLAB ® associates the program with the file name. Too many blanks will make reading harder, though, as one has to scroll through more pages than otherwise necessary. The minimum useful classic VB class (.cls file) can consist of just 1 or 2 lines of code. T��� You typically focus efforts on a single part of your program at a time, working with the code in chunks. 16, No 2, February 1990. Depending on what you count, you get a low or a high line count. In VB.NET, the minimum useful class also consists of 3 lines: Class, End Class and a variable declaration with an initializer. — In VB.NET, definitions are counted just like normal code. This metric counts the physical lines, but excludes classic VB form definitions and attributes. Code that has been commented out exaggerates LLOC' and MCOMM. In addition, comments starting with a dollar sign ($) are not counted as meaningful comments since they are interpreted as special Comment directives in Project Analyzer. These lines are not code, but contain declarations for forms, controls and properties. There should be a message announcing how many steps it took, and the game should end. Some of the file types excluded are project files, solution files, binary files, resource files, HTML files and other related files. To avoid too long files, you might want to set a maximum limit to LINES for files. PHP Code Editor: Have another way to solve this solution? A regular procedure already consists of at least 2 lines of code: the procedure header line and the end line (Sub and End Sub). ", MCOMM% measures commentedness in terms of how many comments there are for each code line. On the other hand, a VB.NET property accessor consists of 3 or 4 lines of code even when the accessor body (Get/Set) is empty. A full-line comment is not a line of code. You can use it to measure productivity, although you need to be cautious, because programming style can have an impact on the values. Functions "Encapsulate" a task (they combine many instructions into a single line of code). Wow! This also suggests that more whitespace should be used in data declarations than in executable code. However, it's not. On the contrary, the Meaningful Comments metric (MCOMM) considers both the full comment lines and the end-of-line comments. How important is it to reduce the number of lines in code? A user should be able to utilize a previously written program (or function) without ever having to look at the code, simply by reading the comments. In fact, there are no comment or whitespace lines in line numbered code. are counted as code. Using double negatives. Modify the code of drawAllBubbles: Add a loop inside the function. There's an exception: Attibute statements are not counted when they're part of a module header, that is, they exist at the start of a file before any source code. Each empty or whitespace-only logical line is counted in LLOW. To avoid too long procedures, you might want to set a maximum limit to LINES for procedures. A regular procedure already consists of at least 2 lines of code: the procedure header line and the end line (Sub and End Sub). You should consider writing a function whenever you���ve copied and pasted a block of code more than twice (i.e. Instead of limiting the file length, you may consider limiting the number of procedures in it by setting a maximum limit on the PROCS metric. LINES counts every line, be it a code, a comment or an empty line. There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors. Both LLOC'% and MCOMM% measure the amount of commentation. PROCEDURE DIVISION is the equivalent of executable procedural code. Even after refactoring some common logic into other functions I am not able to make my calling function shorter than this. ... How many lines will this program print? 6.) A logical line ends where the statement or comment ends. Again, you need to pick your preference. Interpreting the result for Visual Basic development, it seems safe to assume that LLOW% values 8% to 16% are all right. Exception. However, it's possible to put several statements on one line by using the colon ":" or writing single-line If..Then statements. Examples are Declare statements, Event statements, and VB.NET abstract procedure declarations, such as procedure definitions in an Interface and MustInherit declarations in a class. LLOW is calculated from logical lines to make it comparable to LLOC and LLOC'. If you delete features and LLOC stays the same, you may have forgotten to the delete code that was left unused. That's right my friends, I am afraid there is no ground breaking stuff here today. The logical lines of code metric (LLOC) has both advantages and disadvantages. As a special case, line numbers and line labels count as code. When used together with LLOC%, it answers the question "How much of it is real code and how much is comments? The simplest way to measure the size of a program is to count the lines. a. You should always break long code into smaller chunks that can be tested and managed separately. a) Methods should not have more than an average of 30 code lines (not counting line spaces and comments). What is a large project? (This happens because it isn't easy to programmatically distinguish real comments from commented-out code. ) Excluded lines are counted in LINES, though. Since you ran the code through the console, the function is now available, like any of the other built-in functions within R. Running sum.of.squares(3,4) will give you the answer 25.. In the table below you can see various alternatives. An empty line (or a line with just whitespace characters) is not a line of code either. Using lines of code to compare a 10,000-line project to a 100,000-line project is far more useful than when comparing a 20,000-line project with a 21,000-line project.
