    Chocolatey

    Chocolatey

    Chocolatey - the package manager for Windows

    Chocolatey has the largest online registry of Windows packages. Chocolatey packages encapsulate everything required to manage a particular piece of software into one deployment artifact by wrapping installers, executables, zips, and/or scripts into a compiled package file. Package submissions go through a rigorous moderation review process, including automatic virus scanning. The community repository has a strict policy on malicious and pirated software. Many organizations face the ongoing challenge of deploying and supporting various versions of software. Chocolatey allows organizations to automate and simplify the management of their complex Windows environments. Our customers have experienced a massive reduction in effort, improved speed of deployment, high reliability, and comprehensive reporting. Whether you are looking to create your first package or planning to fully automate your entire Windows Lifecycle. Its time to step out of the dark ages and stop doing things manually.

    OpenTabletDriver

    OpenTabletDriver

    Open source, cross-platform, user-mode tablet driver

    OpenTabletDriver is an open-source, cross-platform, user mode tablet driver. The goal of OpenTabletDriver is to be cross-platform as possible with the highest compatibility in an easily configurable graphical user interface. OpenTabletDriver functions as two separate processes that interact with each other seamlessly. The active program that does all of the tablet data handling is OpenTabletDriver.Daemon. The daemon must be started in order for anything to work, however, the GUI is unnecessary. If you have existing settings, they should apply when the daemon starts. The requirements to build OpenTabletDriver are consistent across all platforms. Running OpenTabletDriver on each platform requires different dependencies. Run build.ps1 to produce binary builds to 'bin' folder. These builds will run in portable mode by default.

    NSwag

    NSwag

    The Swagger/openAPI toolchain for .NET, ASP.NET Core and TypeScript

    NSwag is a Swagger/OpenAPI 2.0 and 3.0 toolchain for .NET, .NET Core, Web API, ASP.NET Core, TypeScript (jQuery, AngularJS, Angular 2+, Aurelia, KnockoutJS and more) and other platforms, written in C#. The OpenAPI/Swagger specification uses JSON and JSON Schema to describe a RESTful web API. The NSwag project provides tools to generate OpenAPI specifications from existing ASP.NET Web API controllers and client code from these OpenAPI specifications. The project combines the functionality of Swashbuckle (OpenAPI/Swagger generation) and AutoRest (client generation) in one toolchain (these two libs are not needed). This way a lot of incompatibilities can be avoided and features that are not well described by the OpenAPI specification or JSON Schema are better supported (e.g. inheritance, enum and reference handling). The NSwag project heavily uses NJsonSchema for .NET for JSON Schema handling and C#/TypeScript class/interface generation.

    MSBuild

    MSBuild

    The Microsoft Build Engine (MSBuild) build platform for .NET and VS

    The Microsoft Build Engine is a platform for building applications. This engine, which is also known as MSBuild, provides an XML schema for a project file that controls how the build platform processes and builds software. Visual Studio uses MSBuild, but MSBuild doesn't depend on Visual Studio. By invoking msbuild.exe on your project or solution file, you can orchestrate and build products in environments where Visual Studio isn't installed. Visual Studio uses MSBuild to load and build managed projects. The project files in Visual Studio (.csproj, .vbproj, .vcxproj, and others) contain MSBuild XML code that executes when you build a project by using the IDE. Visual Studio projects import all the necessary settings and build processes to do typical development work, but you can extend or modify them from within Visual Studio or by using an XML editor. Starting with Visual Studio 2022, when you build in Visual Studio, the 64-bit version of MSBuild is used.

    Rubberduck

    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.

    Git Credential Manager

    Git Credential Manager

    Secure, cross-platform Git credential storage with authentication

    Git Credential Manager (GCM) is a secure Git credential helper built on .NET that runs on Windows, macOS, and Linux. It aims to provide a consistent and secure authentication experience, including multi-factor auth, to every major source control hosting service and platform. GCM supports (in alphabetical order) Azure DevOps, Azure DevOps Server (formerly Team Foundation Server), Bitbucket, GitHub, and GitLab. Compare to Git's built-in credential helpers (Windows: wincred, macOS: osxkeychain, Linux: gnome-keyring/libsecret), which provide single-factor authentication support for username/password only. GCM replaces both the .NET Framework-based Git Credential Manager for Windows and the Java-based Git Credential Manager for Mac and Linux. Git Credential Manager is currently available for Windows, macOS, and Linux*. GCM only works with HTTP(S) remotes; you can still use Git with SSH.

In pspad you can select the whole path (../this/is/some/file.php) and open it from the menu. Now you can do the same in notepad++. Just select the whole path and press alt+o, or use the button in the toolbar on top. It will open the file automatically. The plugin understands the relative path.
