---------------------------------------------------------------------- (0007257) dwheeler (reporter) - 2025-09-12 14:43 https://www.austingroupbugs.net/view.php?id=1942#c7257 ---------------------------------------------------------------------- <p> At the meeting on 2025-09-12 I was asked to make some improvements to this, which I plan to do. I'm recording this information here so the plan will be documented <i>and</i> so people can correct me if I misunderstood something. <p> There appeared to be general agreement that these were widely implemented and worthy of including in POSIX. However, at the meeting some needed clarifications were identified: <ol> <li>If standard input is an input (e.g., "-"), what filename is reported? Is it "(standard input)" everywhere, or something else? Ideally there would be a standard answer, and if not, it should be clearly noted that it may vary by implementation. I'll need to see what implementations do in this case. <li>What's the impact of -q and -s? Do they send to standard output? Are they local-dependent? <li>The "-i" (Ignore Case) should refer to Refer to XPD 4.2 - general concepts (case-insensitive) (spelling?). Review the similar references to use the same format. <li>Is "-w" ignore space and tab, or ignore whitespace? The initial draft was inconsistent. There's other whitespace than space or tab. Is it locale-specific? </ol> <p> Once I've completed my investigations, I intend to post an updated proposal that uses a restricted HTML as documented in https://www.austingroupbugs.net/proj_doc_page.php ; this limits HTML tags to p, li, ul, ol, br, pre, i, b, u, em, blockquote. <p> If there's anything wrong/missing in this plan, please let me know.
