I'm not terribly familiar with gyp's internals, but from what I can glean, it
seems that currently only Make supports build-file auto-regeneration after the
.gyp files are changed.
Ninja has functionality specifically to support this (the `generator =` key on
`rule`'s). I believe all it will take is adding the following to the top-level
outputted .ninja file (using the ninja_syntax.py API):
n.rule('regenerate',
command='<reinvoke gyp>',
description='REGENERATE',
generator=True) # <-- Important. Gives it special semantics.
n.build([<.ninja files generated by gyp>], 'regenerate',
implicit=[<gyp files depended upon>])
If someone can point me at how to get at the <...> parts and where is the best
place to do so (somewhere in pylib/gyp/generator/ninja.py I'm guessing?), I'd
be glad to submit a patch, but I wasn't able to quite decipher the logic of
what is happening in the .ninja generator (TBH I didn't try very hard...).
I can sort of piece together how to do some parts of that from make.py's
WriteAutoRegenerationRule() function, but it's still kind of foggy.
