Re: P2717R1, EcoIS Introspection

My assumption is that If you can launch a process, you know (or can figure out) its file location. And when you know the tool's exe full path, it is easy to change the extension on that path to, say, .toolcapabilities or .capabilities.json (or whatever we agree on) and this will be the capabilities file.

The mechanism is effectively similar to .exe.config and .manifest on Windows.

An interesting idea, but I don't see how "easy to find" could be possible. I would probably end up asking the compiler to tell me where the file is, which defeats the purpose. If process startup costs are an issue, I suspect some form of caching would work better. As for maintainability, nothing prevents compiler vendors from having the data in an external file, even if the official interface is a command line option.

The paper proposes a call to an executable to produce a json format with the capabilities info. I am wondering if having a json file near the executable which would contain full info about what this tool supports would be more beneficial.

An external (but easy to find) file will allow getting the tool information even without launching its process, which would be preferred in perf sensitive scenarios. I also think that it would be easier for tool vendors to create (and maintain) this file rather than to implement the suggested functionality in code.

I think it should be at least included as a option.

Following up on the discussions.. I've made some more edits to the paper (https://urldefense.com/v3/__https://isocpp.org/files/papers/D2717R2.html__;!!A4F2R9G_pg!Z60yxNvejpBrhjfgzgKxEcefEEJFti7QDn-wk-AMGVSBhrH1zzSVq-EUjERlQjZ82Oa0zLRWfR2tyuFD$ ) and wording PR (PDF attached).
