New submission from Pablo Galindo Salgado <pablog...@gmail.com>:
When inspecting keyword parameters in a function call, the keyword is stored as a string and not as a AST node: >>> import ast >>> r = "f(a, xxxxxxxxxxa = 34, y=23)" >>> node = ast.parse(r) >>> ll = node.body[0].value.keywords[0].arg >>> node.body[0].value.keywords[0].arg 'xxxxxxxxxxa' this makes impossible to locate the keyword in the code using the AST as it lacks AST attributes (lineno, col_offset, end_lineno, end_col_offset). On the other hand, this does not happen with args, that has the meta-information: >>> node.body[0].value.args[0].id 'a' >>> dir(node.body[0].value.args[0]) So one can locate the arg string using: >>> r[arg.col_offset:arg.end_col_offset] 'a' For this reason, we should add the same information to keyword nodes. ---------- components: Interpreter Core messages: 365509 nosy: pablogsal priority: normal severity: normal status: open title: Add line and column information for keywords in the AST versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40141> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
