Unless an emergency arose forcing others to check out the code, only the developer assigned was permitted to manage that segment of the code. This caused inefficient management of projects. Code merging gives developers the ability to integrate their code after changes or bug fixes.
The developers need to have confidence that their integration efforts are smooth and complete without any errors. When conflicts do occur that prevent the tools from merging automatically, they are reported back to the developers. While the solutions have become more robust, DevOps and Agile methodologies help to keep changes small, which reduces the need to merge large chunks of code. Hence, developers gain the confidence they lost from traditional development methods of merging large blocks of code.
Code merge tools can help teams identify conflicts. But, developers still need to engage in open communication with each other when working on the same code. Stand-up meetings are a great place for them to discuss conflicts and other issues. When choosing a code merge tool, you need to factor in several attributes. The cost is always one of the biggest. Functionality is just as important. Developers should also consider the team size when choosing a tool. The benefits of a visual tool are obvious.
You can see the changes in a side-by-side comparison. However, there will be situations where the visual tools may not handle what you are trying to do. In this case, knowing and using the command-line versions can help you solve your situation. The following list describes several tools on the market and should help you in choosing a merge tool. Several of the tools are open source which means you can easily try them with no monetary commitment.
Git is a popular option for developers. It is more than a merge tool, but that is one of the main aspects of the tool. Git prides itself on having the best branching functionality in the industry. Many users of the software agree. In most cases, it is taken care of by using static analysis tools like PyLint or Flake8. These tools are prone to a lot of noise and false positives that make code reviews hard.
Code review tools can cut many pain points. It can identify code complexity and help us find and fix problematic code. With the tool's findings, the code violations can be kept in check, thus keeping the review process faster and efficient.
DeepSource provides static code analysis against various general-purpose programming languages like Python, Javascript, Golang, and more. DeepSource provides customization and the ease with which it allows us to perform static analysis on the Python code.
DeepSource generates a Configuration File , embedded in the repository, and the code is continuously analyzed. DeepSource provides a low false-positive rate and resolution time, compared to various other static code analysis tools. DeepSource provides access to framework-related issues that makes it easy for maintainers to review. Besides that, DeepSource also makes it easy to operate on private repositories.
With every pull request or commit, a private token is used to fetch the code. The analysis is then run in an isolated environment. Once the analysis is complete, the codebase is purged, mitigating risks of security violations. Codacy is another tool that provides code review and code coverage reports for various general-purpose programming languages like Python. Codacy covers a wide variety of issues like code coverage, duplication, complexity, and more. It helps the developers to keep the code quality intact and the code review clean.
However, Codacy suffers from a compounded setup that requires a lot of configuration and a high false-positive rate. SonarQube provides continuous inspection of code quality to perform automatic reviews.
Its Static Code Analysis Tool can smell bugs, anti-patterns, and even security vulnerabilities in Python. SonarQube implements the Code Analysis functionality through two of its tools. The Sonar Scanner allows the implementation of the analysis, which goes back to the SonarQube Server, where the results are managed and persisted.
Setting up SonarQube for a Python Project is tricky because it requires installing packages and plugins to set up the client analysis and server storage. You can check out the official documentation to know more about SonarQube configuration for a Python project. Veracode is yet another popular code review Tool for Python. For this roundup we have compiled a list of 15 Best Code Review Tools for Developers that will help you to save developers time in hunting down false positives.
Following tools are cheap, easy to install and produce accurate results and review code quickly and cost efficiently. Gerrit is a web based code review system, facilitating online code reviews for projects using the Git version control system.
Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer. Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.
This is one of the best code review tool from Google wherein users can discuss the defects in the code and review the code. Codeplex provides a complete solution for team system code reviews, and this tool and has become very popular with programmers. This code review tool uses the benefits of team system for reducing waste. Barkeep is a fast, fun way to review code. Engineering organizations can use it to keep the bar high. It marks every line of code which is found different between two files in Yellow color.
You still need to find exact error or difference between dissimilar lines of the code. Apart from standard code comparison, you can also compare the binary codes of two files by selecting its Compare As Binary option. This software also offers various tools to fix errors like replace all changes from left or right file , replace the active change from left or right , etc.
Quick toggle buttons to move to next or previous differences are also available in it. After fixing the error, you can save changes in one or on both source files. Diffuse is the next free code comparison software for Windows. In this software, you can compare two code files of various programming languages. In it, you just need to load two code files to find out the lines which are different from each other, along with exact errors and differences. It shows exact differences in a slightly darker shade than the highlighted line.
It also provides direct buttons to jump from one difference to other like next difference , previous difference , first difference , etc. In it, you also get merge features using which you can merge left file with the right side file or vice-versa. After comparing and correcting differences between code files, you can save the changes in original code files.
ExamDiff is another one of code comparison software for Windows. Using it, you can compare up to two code files containing an almost similar piece of code. When you load both files, it shows both files side by side. In both files, you can view some highlighted line in Yellow color to show lines which are different.
However, you still need to find the exact difference between codes. In this software, you can also easily move from one difference to another using its Next or Current Difference button. If you only want to view all dissimilar line of codes, then use its Show Only Differences button.
Some other useful features that you get in it are: show only first file , show only second file , swap files , re-compare files , horizontal and vertical comparison , etc. Files Compare Tool is the next free code comparison software for Windows. Using this code compare software, you can easily compare two code files and find out the differences between them.
It opens up files in a side by side fashion that makes comparison much easier. To indicate the differences, it marks dissimilar lines in Yellow and exact differences in dark Yellow color. To remove differences between files, you can either merge both files or copy the selected line of codes to the other file using available tools. All the changes can easily be saved in their original files.
