In the Visual C++ and Visual C# compilers, error messages have unique IDs. This makes them easy to google, and information about each error can easily be created and enumerated in a wiki or other database.

These error codes need not necessarily be the same in DMD as in GDC, LDC, or other D compilers, but at least within DMD it would be nice to have consistent IDs between releases.

I think this enhancement is a good idea, despite requiring some work to be implemented.

It's much better for error message IDs to be standard for all D compilers, to simplify both the documentation and the ease for the programmer to debug code using different compilers. I think the C# error numbers are the same between dotnet and mono.

Yeah, I had this thought before too. A page with a list of IDs, error message descriptions and how to work around them and fix the code would be very useful to have.

Currently the only thing we have is this: http://dlang.org/warnings.html

Note that we should consider making and distributing a simple text file which is then processed and converted into an HTML file.

The reason why is that it would allow IDE tools to read this text file and then display the full information of a given error/warning ID.
