![]() Libs or *Libs* - all files, the path to which contains the subdirectory, the name of which is equal to or contains 'Libs'. ![]() If the symbols "*" aren't specified, they will be added automatically anyway, so both options are equal. \Libs\ or *\Libs\* - all files in the directories, the path to which contains the subdirectory "Libs" will be excluded.c:\Libs\ - all files in this directory and its subdirectories will be excluded.To start editing, you need to click a button with three points.Įxamples of acceptable masks for the PathMasks list: However, in your project, the directory with the ZLib library can be called not "zlib", but, for example, "zip_lib". By default, names of some directories are already included in the list. If in the full file name there is one of specified names, the analysis won't be performed for this file. Editing a list of directories that the analyzer won't check. You can read about how to use PVS-Studio to check Java code in IntelliJ IDEA here.Īfter PVS-Studio installation and its integration in Visual Studio, users get an additional item "PVS-Studio" in the main menu and the window for working with error messages:įigure 3. In this article, we'll take a closer look at PVS-Studio, checking the code in C, C , and C# languages. The analyzer is superbly integrated into the Visual Studio 2010 - 2019 and IntelliJ IDEA IDEs. PVS-Studio is a static analyzer that detects bugs and potential vulnerabilities in the source code of applications in C, C (other supported extensions: C /CLI and C /CX), C# and Java on Windows, Linux and macOS platforms. For example, the PVS-Studio static code analyzer can be run in a background mode right after compilation and in case of finding potential errors will notify a programmer. ![]() Static analysis tools allow detecting a large number of errors, typical for the stage of code designing, which significantly reduces the cost of the whole project development. McConnell) Click on the picture to enlarge. Average cost of correcting defects depending on the time of their appearance and detection in code (data in the table is taken from the book 'Code Complete' by S. Thus, according to the book "Code Complete" by McConnell, error detection at the code testing stage is ten times more expensive than at the stage of code designing (coding):įigure 1. The earlier an error is detected, the less expensive it is to correct it. The main advantage of static code analysis is the opportunity to greatly reduce the cost of eliminating defects in a program. Needless to say, we will tell you about the PVS-Studio analyzer. The list of languages for which there are static code analyzers is quite large (C, C , C#, Java, Ada, Fortran, Perl, Ruby. A large list of static analyzers is available on Wikipedia: List of tools for static code analysis. There are many commercial and free static code analyzers. If the reader is interested in precise numbers, I suggest you reading the article " PVS-Studio ROI". However, the ratio price/benefits makes the static analysis quite a useful practice, applied by many companies. Of course, a program won't substitute a full-fledged code review, done by a team of developers. They earnestly analyze the source code of programs and give recommendations to programmers on reviewing certain code fragments. The compromise solution is static analysis tools. On the one hand, we want to review code regularly. It's necessary to gather several programmers to review newly written or rewritten code after the modifications made in it. However, it has a significant drawback - high cost. Joint code review is a wonderful methodology. Static analysis can be considered as a process of automated code review. Static code analysis is the process of detecting errors and flaws in the source code of programs. What is static code analysis and why we need it
