[issue33095] Cross-reference isolated mode from relevant locations

New submission from Nick Coghlan <ncoghlan@gmail.com>: In https://bugs.python.org/issue33053#msg313966, jwilk noted that it isn't obvious from https://docs.python.org/3/using/cmdline.html#cmdoption-m how to keep the current directory from being added to `sys.path` when using the -m switch. The answer is to pass the `-I` switch as well (to activate isolated mode), but there's no cross reference to help readers discover that fact. https://docs.python.org/3/using/cmdline.html#id2 is the main documentation for isolated mode, so the steps needed to close this issue are: 1. At least add a reference from the -m switch documentation to the -I switch documentation 2. Review the other parts of the `using` docs that describe how `sys.path` is initialised, and reference the -I switch documentation where relevant ---------- assignee: docs@python components: Documentation keywords: easy messages: 314022 nosy: docs@python, jwilk, ncoghlan priority: normal severity: normal stage: needs patch status: open title: Cross-reference isolated mode from relevant locations type: enhancement versions: Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue33095> _______________________________________

Karthikeyan Singaravelan <tir.karthi@gmail.com> added the comment: There are four parts where I could see sys.path manipulation being mentioned while running scripts : -c option (https://docs.python.org/3/using/cmdline.html#cmdoption-c) -m option (https://docs.python.org/3/using/cmdline.html#cmdoption-m) - (input option) <script> (running as script) For some reason I am not able to hyperlink to - and <script> parts since they are not a command line option but a method to execute code. I could sys.path references in windows (https://docs.python.org/3/using/windows.html#finding-modules) where `._pth` file is mentioned to completely override sys.path. I am new to adding documentation so add in if it needs a simple reference or explain the option which I feel redundant and useful at the same time kind of missing the point of cross-referencing. I am attaching a patch for `-m` and <script> option. Feel free to add comments and if I am missing something.

Nick Coghlan <ncoghlan@gmail.com> added the comment: xtreak: if you're familiar with GitHub workflows, then we now accept docs and code updates as GitHub PRs: https://devguide.python.org/pullrequest/ The parts about running the tests aren't exactly relevant here, what's more relevant is building the documentation: https://devguide.python.org/documenting/#building-the-documentation In relation to your draft patch, I think that's a good starting point, but for -c and -m, it's the current directory that gets omitted, rather than "the script's directory" (that isn't well defined when anything other than a path is passed in). For making "-" and "<script>" hyperlinkable, you'll need to add a label definition to the Sphinx source code immediately before those description sections. I'd suggest ".. _cmdarg-dash:" and ".. _cmdarg-script:" so the resulting anchors look similar to the option ones, without being the same. ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue33095> _______________________________________
