[issue17515] Add sys.setasthook() to allow to use a custom AST optimizer

Brett Cannon added the comment: The closing of this issue inspired me to think of a better way to do this, and I think providing something in importlib.util that accepted a NodeTransformer as an argument to a function that compiled source files to bytecode files would fill this issue thanks to

STINNER Victor added the comment: I'm not more interested to work on my astoptimizer project, and nobody looks to need sys.setasthook(), so I prefer to close the issue. -- resolution: -> out of date status: open -> closed ___ Python tracker

[issue17515] Add sys.setasthook() to allow to use a custom AST optimizer

Brett Cannon added the comment: And that's fine as it allows for more explicit control over what gets optimized. Basically if there is a global hook directly into the compiler there needs to be more control over detecting it's being optimized, what to do about .pyo files, etc. At least at the

[issue17515] Add sys.setasthook() to allow to use a custom AST optimizer

New submission from STINNER Victor: I wrote an optimizer rewriting the AST to implement various optimizatoions: https://bitbucket.org/haypo/astoptimizer To be able to use it, or use any other kind of AST transformation, I propose to add a new sys.setasthook() function to set a custom AST hook.
