Provides better visibility into what the build is currently doing. Motivated by slow node.js downloads making the build appear stuck. You can test this out by running ./tools/install-n2 then building normally. Please report any problems, and 'cargo uninstall n2' to get back to the old behaviour. It works on Windows, but prints a new line each second instead of redrawing the same area. A couple of changes were required for compatibility: - n2 doesn't resolve $variable names inside other variables, so the resolution needs to be done by our build generator. - Our inputs and outputs in build.ninja need to be listed in a deterministic order to avoid unwanted rebuilds. I've made a few other tweaks so the build file should now be fully-deterministic.
