Some suggestions of engineering formats/languages

I'm a noob programmer, but I also a noob hardware developer 🤯

Although there is also a lot of open source hardware in GitHub, many hardware engineers have no idea with linguist. This is probably why I keep getting unsupported hardware formats when editing .gitattributes. So now I list up some common engineering formats, hoping to get support.

It is worth mentioning that some common formats in hardware design already exist in languages.yml. Such as KiCAD Altium Designer Eagle Gerber Image Wavefront Object STL... Yes, none of them are programming languages, they are considered as data by default, and the identification of these file types must be manually increased in .gitattributes. But it still makes sense to expose these formats as languages, because it really helps hardware designers quickly find the items they need.

It's really important to differentiate these formats from design softwares with language statistics. Because like when a Python developers is looking for sorting algorithms, they wouldn't expect to find a repo written in Java. That's why I wrote an all-in-one .gitattributes and use it in all my hardware projects.

Those formats below are what I wish to add support for. They are similar to the existing ones, also files of circuit design software or files of 3D/2D design softwares:

1 LCEDA (a.k.a EasyEDA) -->【Wikipedia】<--

A free circuit design software. Similar to KiCAD, Eagle and Altium Designer.

3 Computer Aided Design (CAD) -->【Wikipedia】<--

Common format standard. The CAD file in the narrow sense refers to .dwg and .dxf format, which is the most suitable format for CAD packages. The most mainstream CAD package is AutoCAD.
