New submission from Nat Hillard: When using the argparse argument fromfile_prefix_chars to obtain command line arguments from a file, it is not possible to make use of bash environment variables within this file.
Ideally one would be able to `export BAR='/Users/x/Desktop/bar'`, and then give arguments such as: --foo $BAR and have this correctly expanded at read time to --foo '/Users/x/Desktop/bar'. To my knowledge, this is currently only possible if you give the arguments directly via the command line: python test.py --foo $BAR It would be great to be able to use environment variables within files as well! ---------- components: Library (Lib) messages: 169958 nosy: ZhuangZi, bethard priority: normal severity: normal status: open title: argparse cannot parse bash variable arguments in file-given arguments type: behavior versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15874> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
