STINNER Victor added the comment: *If* the PEP 511 is accepted, it will be super easy to start with an implementation in pure Python.
But I think that we should benchmark the overhead of the Python API of PEP 511, because we need to convert all AST internal objects to Python objects, run the AST optimizer, and then again convert Python objects to internal AST objects. For a long running process, the time to compile a .py file doesn't matter. For a short script, it matters. At least, we need to compile the script itself. By the way, would it be insane to *not* optimize the script when running "python script.py"? > Now with the Constant node this should be easy. ast.Constant is *not* emited by the compiler to not break backward compatibility. I *know* that there is no stable API on AST, but I noticed some issues when working on my AST project. For example, pip doesn't work because an internal library uses AST and the code doesn't handle ast.Constant (it's probably super easy to fix it). I'm open to change the compiler to emit ast.Constant directly, but maybe only in "optimized mode" (ex: python -O?). ast.Constant for tuples and frozensets has a limitation: it doesn't store the location of items (line number, column offset). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26297> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
