Path expansion in builds doesn't take take build variables in context

Thanks, opened https://github.com/evmar/n2/issues/83 about this one.

Path expansion in builds doesn't take take build variables in context

(And now fixed, maybe.)

better control over subcommand output

Digging into the LLVM build, it appears check-lld is tagged into the `console` pool.

Use serde instead of hand-rolled serialization, take 2

Huh, it's surprising we no longer see the performance difference from that previous change. Two guesses: - maybe lto helped? - what size is your `build1/.n2_db` file? maybe it's too...

Use serde instead of hand-rolled serialization, take 2

Looking through the bincode docs, it's a little disappointing that even it uses big sizes like u64 for lengths, but it probably doesn't matter too much, and maybe using their...

Use serde instead of hand-rolled serialization, take 2

If you build the `check-llvm` target in LLVM, it builds a lot more files than clang-format. I think you can interrupt the build at any point (via ctl-C) and the...

Use serde instead of hand-rolled serialization, take 2

Based on this branch I created a PR that has just the serde parts without the refactoring: https://github.com/evmar/n2/pull/64/files Some random thoughts: - I don't love how this adds random copies...

It just occurred to me that a reasonable place to put configuration like this is in the ninja file itself, given that the generator is the tool where you know...

Give priority to slow actions

How is the external file generated? We did some experimentation around this in Ninja but in my recollection we never found a heuristic that reliably improved things. For example maybe...
