Document setting up IDE integration with BlocksDS

[asiekierka]

From a certain forum:

The problem is that outside of setup there is no documentation/tutorial at all for integrating BlocksDS support into an IDE, whether it its VS Code, the full fat VS or any other C/C++ IDE available out there. Has anyone tried so far to include BlocksDS functions inside an IDE and compile a program with it in a terminal? I am sorry if this topic exists already.

Wonderful solves this by providing some tools and some patches on top of GCC to generate compile_commands.json files that most IDEs can ingest, however this will further deepen BlocksDS's dependency on Wonderful. There are probably other options.

As a quick and dirty solution, it may be worth documenting clangd's compile_flags.txt which can specify options (defines, include paths, target...) across an entire project. It's quite easy to set up and I use it myself in most C and C++ projects I work with--although I don't believe it would work for arm7+arm9 projects given that the options are project-wide. I'm not sure what behavior clangd follows if there are different compile_flags.txt in subdirectories, but that could be a possible solution.

There's also the possibility of making a tool that generates compile_commands.json by traversing the specified source directories and creating entries with the proper arm7/arm9 flags, although something like bear could just be used instead (I've found it to be a bit finicky though).

Personally, I just went for implementing -MJ in GCC; it's convenient but, again, this makes it incompatible with non-Wonderful toolchains, as it's a non-upstreamed patch.
