In plain English

This is a macOS tool for people who work with UYAP, the Turkish national court and justice system's document platform. UYAP uses a file format called .udf for its documents, and by default macOS has no idea how to display those files in Finder. This tool fixes that by adding two things: a QuickLook preview (press the space bar on a .udf file and a readable preview pops up) and a thumbnail image on the file icon so you can see at a glance what the document contains. The tool also installs a read-only viewer application. You can open a .udf file in it, read the text, and copy from it. There is a button inside the viewer to open the file in the official UYAP editor if you have that installed. The tool does not change what happens when you double-click a .udf file: double-clicking still opens the official UYAP editor as before. This tool only adds the preview and thumbnail layer on top. Installation is a single terminal command. It downloads a shell script that builds the tool from source code on your own machine, then installs it to your Applications folder and registers the QuickLook extension. Because it is built locally with an ad-hoc signature, you will not see a Gatekeeper security warning. If the preview does not appear after installation, you may need to enable the extension manually in System Settings under Login Items and Extensions, in the QuickLook section. The README is written in Turkish, reflecting that the tool is primarily aimed at legal and administrative workers in Turkey who use the UYAP system daily.
