However, I think we can go further. Currently, only (identity #o755 / 493) works, however I think it would be good if it worked like chmod and accepted most of the following forms: ⁃ `#o755' ⁃ `755' (because people are used to this, as technically misleading as it may be, as long as we can tell “:tangle-mode 356” from “:tangle-mode (identity #o544)”) ⁃ `rw' (equivalent to a=rw, and so #o555) ⁃ `a=rw,u+x' (equivalent to #o755) [hardest to support, so maybe?] And then I’d also be in favour of accepting ⁃ `rw-r--r--' (equivalent to #o544) I think as long as it’s clear what’s intended, and it’s not some home-baked non-standard format, or terribly annoying to support — why not? All the best, Timothy
