Improve ast CLI with new options: --feature-version, --optimize, and --show-empty #133367
Description
Feature or enhancement
Current options:
» ./python.exe -m ast --help
usage: python.exe -m ast [-h] [-m {exec,single,eval,func_type}] [--no-type-comments] [-a]
[-i INDENT]
[infile]
positional arguments:
infile the file to parse; defaults to stdin
options:
-h, --help show this help message and exit
-m, --mode {exec,single,eval,func_type}
specify what kind of code must be parsed
--no-type-comments don't add information about type comments
-a, --include-attributes
include attributes such as line numbers and column offsets
-i, --indent INDENT indentation of nodes (number of spaces)
Basically, our CLI is an interface to ast.dump + ast.parse, ast.parse.
But, ast.parse has several important options that are missing right now. I propose to add them:
--feature-version- and
--optimizefromparse --show-emptyfromdump

cc @donbarbos, will you be interested in working on this issue?
