| Summary | 0000026: Regex match does not capture all characters to end of line | ||||
| Description | I've got an Ansible Vault data file that I'm making magic for; the second and subsequent lines of the example file should be irrelevant (for magic purposes), but I added placeholder lines (to match my actual file) for grins. On the fourth line of my magic config file (the one that starts with ">>&1 regex/1l") my understanding is that "regex/1l" means that I'm specifying a regular expression, and that regex will be searched for in the block starting at the character following the previous match and ending at the end of the line. (It's this last bit, "...and ending at the end of the line", that I suspect is where my understanding is incomplete.) HOWEVER, for some reason the last character of the line is getting chopped off; as you can see in the reproduction, file is only printing "AES25" in the output, rather than "AES256". This agrees with my testing, where if I try to match the regex "AES256" it fails, but matching "AES25" works. | ||||

| Additional Information | This testing is against version 5.32; apologies for not using the latest version, but it's what I have on my system and I'm kind of expecting this to be a problem with my magic file rather than a bug anyway, so I thought I might skip getting the latest version built and running unless it's necessary. I've attached the three files in question; there's nothing special about them as far as I know, but I suppose you can't be too careful. :) | ||||
