AWS IoT Device Defender Library
Client library for using AWS IoT Defender service on embedded devices
The Device Defender library enables you to send device metrics to the AWS IoT Device Defender Service. This library also supports custom metrics, a feature that helps you monitor operational health metrics that are unique to your fleet or use case. For example, you can define a new metric to monitor the memory usage or CPU usage on your devices. This library has no dependencies on any additional libraries other than the standard C library, and therefore, can be used with any MQTT client library. This library is distributed under the MIT Open Source License. This library has gone through code quality checks including verification that no function has a GNU Complexity score over 8, and checks against deviations from mandatory rules in the MISRA coding standard. Deviations from the MISRA C:2012 guidelines are documented under MISRA Deviations. This library has also undergone static code analysis using Coverity static analysis. -

Rubberduck
Every programmer needs a rubberduck. COM add-in for the VBA & VB6 IDE
Rubberduck aims to bring the VBIDE into this century. Rubberduck understands Classic-VB code like no other add-in, giving it superior static code analysis capabilities that go far above and beyond what is possible with simple text-based analysis. Avoid common pitfalls (some not-so-common) with dozens (100+) of configurable inspections. Gain full control over module and member attributes, create a virtual folder hierarchy, and document modules and procedures, all with special comment annotations. Navigate a Classic-VB project like never before, quickly locating identifier references, interface implementations, and anything else that has a name. Add a full folder structure for organizing your modules. Write code that runs your code and verifies its output is as expected, given controlled inputs. Organize tests into categories, run them directly in the VBIDE, and view results in a dedicated explorer toolwindow. -

PHP Parser
A PHP parser written in PHP
This is a PHP 5.2 to PHP 8.0 parser written in PHP. Its purpose is to simplify static code analysis and manipulation. A parser is useful for static analysis, manipulation of code and basically any other application dealing with code programmatically. A parser constructs an Abstract Syntax Tree (AST) of the code and thus allows dealing with it in an abstract and robust way. As the parser is based on the tokens returned by token_get_all (which is only able to lex the PHP version it runs on), additionally a wrapper for emulating tokens from newer versions is provided. This allows to parse PHP 7.4 source code running on PHP 7.0, for example. This emulation is somewhat hacky and not perfect, but it should work well on any sane code. Support for pretty printing, which is the act of converting an AST into PHP code. Please note that "pretty printing" does not imply that the output is especially pretty. -

Ruff
An extremely fast Python linter, written in Rust
An extremely fast Python linter, written in Rust. Ruff aims to be orders of magnitude faster than alternative tools while integrating more functionality behind a single, common interface. Ruff can be used to replace Flake8 (plus dozens of plugins), isort, pydocstyle, yesqa, eradicate, pyupgrade, and autoflake, all while executing tens or hundreds of times faster than any individual tool. Ruff is extremely actively developed and used in major open-source projects. Ruff can be configured through a pyproject.toml, ruff.toml, or .ruff.toml file (see: Configuration, or Settings for a complete list of all configuration options). Ruff supports over 500 lint rules, many of which are inspired by popular tools like Flake8, isort, pyupgrade, and others. Regardless of the rule's origin, Ruff re-implements every rule in Rust as a first-party feature. -

Pylint
It's not just a linter that annoys you!
Pylint is a static code analyzer for Python 2 or 3. The latest version supports Python 3.7.2 and above. Pylint analyses your code without actually running it. It checks for errors, enforces a coding standard, looks for code smells, and can make suggestions about how the code could be refactored. Projects that you might want to use alongside pylint include flake8 (faster and simpler checks with very few false positives), mypy, pyright or pyre (typing checks), bandit (security-oriented checks), black and isort (auto-formatting), autoflake (automated removal of unused import or variable), pyupgrade (automated upgrade to newer python syntax) and pydocstringformatter (automated pep257). Pylint isn't smarter than you: it may warn you about things that you have conscientiously done or checks for some things that you don't care about. During adoption, especially in a legacy project where pylint was never enforced. -

tfsec
Security scanner for your Terraform code
tfsec is a static analysis security scanner for your Terraform code. Designed to run locally and in your CI pipelines, developer-friendly output and fully documented checks mean detection and remediation can take place as quickly and efficiently as possible. tfsec takes a developer-first approach to scanning your Terraform templates; using static analysis and deep integration with the official HCL parser it ensures that security issues can be detected before your infrastructure changes take effect. Checks for misconfigurations across all major (and some minor) cloud providers. Applies (and embellishes) user-defined Rego policies. Supports multiple output formats: CLI, JSON, SARIF, CSV, CheckStyle, and JUnit. Configurable (via CLI flags and/or config file). Very fast, capable of quickly scanning huge repositories. Plugins for popular IDEs available (JetBrains, VSCode and Vim). -

SpotBugs
A tool for static analysis to look for bugs in Java code
SpotBugs is a program that uses static analysis to look for bugs in Java code. It is free software, distributed under the terms of the GNU Lesser General Public License. SpotBugs is a fork of FindBugs (which is now an abandoned project), carrying on from the point where it left off with the support of its community. Please check the official manual for details. SpotBugs requires JRE (or JDK) 1.8.0 or later to run. However, it can analyze programs compiled for any version of Java, from 1.0 to 1.9. To build the SpotBugs plugin for Eclipse, you'll need to create the file eclipsePlugin/local.properties, containing a property eclipseRoot.dir that points to an Eclipse installation's root directory (see .travis.yml for an example), then run the build. -

reviewdog
Automated code review tool integrated with any code analysis tools
I’d like to introduce reviewdog! An automated code review tool working with any lint tools and supports local run as well. “reviewdog” provides a way to post review comments to code hosting services, such as GitHub, automatically by integrating with any linter tools with ease. It uses any output of lint tools, with translation if required, and posts them as a comment if the file and line are in diff of patches to review. reviewdog also supports running in a local environment to filter the output of lint tools by diff. We can use various linters and static code analysis tools to detect such problems in local machines, editors, CI services. However, here is the problem. Static analysis tools may report false-positive results. Reporting false-positive results itself is ok, but due to the false-positive results we cannot make build fail and it becomes difficult for us to find true positive results from messed up analysis results. -

DiffReport
Code Difference report
Often I have seen some Huge Maintenance Projects it is always very difficult to track the incremental files for each release and If we want to do that we need to checkout both the branches and use some UI based tool to get the diff of the files finally we end up waiting in front of the PC for a long time and do this job. In many cases we spend more than 2 hrs/day. The time increases if there are more such parallel releases and at the end of the day 1 developer does it as full time job and has zero productivity. I thought of adding value here. This just gets the diff files. Can be used for Static code analysis like PMD to do PMD only for the delta. The current status of the project is in Development". If you wish to add something please mail me. -
