![]() ![]() V3001 There are identical sub-expressions 'SK = SymKind.field' to the left and to the right of the '||' operator. It's hard to say how to fix this error, since the TypeFactory class has a lot of fields. I think it's quite difficult for a person to notice problems in such code. In the original version the if expression was written in one line. Here the developer compares the same value with the TypeFactory.ObjectType value. If your Community Edition license expires (1 year), you will have to uninstall, download a new version, then install that. & (piled_type = TypeFactory.ObjectType || NETGenerator.cs 8518 private void AssignToDereferenceNode(.) V3001 There are identical sub-expressions 'piled_type = TypeFactory.ObjectType' to the left and to the right of the '||' operator. In the original version the entire return expression is written in one line. Note that the code was formatted for readability. PascalABC.NET is representative of the line of modern Pascal languages along with Delphi XE and Oxygene. If we look at the declaration of the PlatformTarget enumeration, we can assume that the code should look like this: bool IsDotnet5()Ĭ5macos The PascalABC.NET compiler generates code that runs as fast as C code and slightly slower than C++ and Delphi. In this code fragment the developer re-compares the IsDotnet5() method with the value of enumeration 5linux. Public enum PlatformTarget Ĭ5win ||Ĭ5linux ||Ĭ5linux NETGenerator.cs 461 public class CompilerOptions Download the latest version of PascalABC.NET with build-in form designer. V3001 There are identical sub-expressions to the left and to the right of the '||' operator. People don't always have it due to fatigue and other reasons. Besides, such errors show an important advantage of static analysis tools: constant attention to detail. ![]() This means PVS-Studio will definitely have a job to do. Unbelievable, but developers make such errors over and over again. Let's start with classic - copy-paste errors. Despite this, when re-checking the project, we managed to find some new and interesting errors. ![]() This was an additional problem, since I had to exclude old errors from the report. However, only developers can fix those errors. After publishing an article, we always send bug reports to the developers. Unfortunately, many errors found in 2017 were never fixed. This is important when you work with such large projects. Don't forget about our new feature " Best Warnings" which immediately shows the most interesting errors. Sa version WDE permet également de lutiliser à travers une interface web. NET (ou Mono) en Pascal, grâce à une extension du langage adaptée au framework. By the way, you can easily request the PVS-Studio trial version. PascalABC.NET est un environnement de développement (Windows) ou un compilateur en ligne de commande (Linux) permettant de créer des applications. Please take this fact into account if you're going to check the source of PascalABC.NET yourself. Note that while I was writing the article the code may have changed. A developing project means that old errors are fixed, and the new ones appear.įor analysis, I took the source code from GitHub from. This was an additional motivation to write this article. Good news - it's no point in re-checking the "abandoned" project. In Pascal abc.net variables can be defined within the body of the program between begin and end keywords.The principle of locality: a variable is defined immediately before it is used. The latest version 3.8.1 was released in August 2021. Variable Definition & Assigning a value to it. You can visit the project's website to read the description and see that the project is developing. PascalABC.NET is a modern implementation of the Pascal language on. After that I was considering the idea of re-checking the project, but I didn't have time for that. Of course, we never planned that, it was a coincidence. It looked like we did it on purpose: wrote an article about errors found in their project and went to the conference to discuss those errors with the developers. RebuildReleaseAndRunTests.bat builds the project in Release-mode, rebuilds the pas-units and runs tests (run with administrative privileges). Right after we published " Analysis of PascalABC.NET using SonarQube plugins: SonarC# and PVS-Studio", we accidentally crossed paths with the developers at one conference. Run RegisterHelix.bat on first use to install the HelixToolkit.dll and in GAC. It has a form designer and it’s FREE.I have an interesting story about PascalABC.NET. It’s major influences are: Lua, Python, Ruby, C, C# and Basic. One can even change keywords to mimic, say the Basic syntax. The syntax is extremely flexible (maybe too flexible) as it can mimic several popular constructs. I’ve only started to mess with it and I’m currently reading the book “ Beginning Ring Programming”. ![]()
