QuickOpen Plugin for notepad++
plugin for notepad++
This plugin mimics the "open selected file" in PSPad. I am a PHP developer and i often see an 'require_once("../this/is/some/file.php");'. 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. The code is also available on https://bitbucket.org/sgezel/quickopenplugin -

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. -

QuickLook
Bring macOS “Quick Look” feature to Windows
Bring macOS “Quick Look” feature to Windows. One of the few features I missed from macOS is Quick Look. It allows users to peek into a file's content at lightning speed by just pressing the Space key. Windows, on the other hand, does not have this handy feature, until now! I am aware that several alternatives are already available on the Internet (e.g. WinQuickLook and Seer). Despite these options, I still decided to craft another one by myself, because they are either not being actively developed, lack variety, or ask for some. Tons of supported file types. Fluent design. Touchscreen friendly. HiDPI support. Preview from the open and save file dialog. Preview from 3rd-party file managers. Easily extended by plugins. Strict GPL license to keep it free forever. Preview next file by clicking on it or using arrow-keys (arrow-keys move selection in the background if the preview window is not in focus). -

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. -
