* cat(1): -n flag: correctly enumerate files with more than INT_MAX linescheloha2020-12-111-3/+4
| | | | | | | If we bump 'lines' from an int to an unsigned long long we can trivially support files with more than INT_MAX lines. ok millert@
* cat(1): misc. style(9)cheloha2020-12-041-11/+11
| | | | | | | - Use getprogname(3) instead of __progname. - Sprinkle in some missing braces. - Prefer err(..., NULL) when malloc(3) fails. - Remove an unnecessary cast to from ssize_t to size_t.
* cat(1): simplify argv processing loopscheloha2020-12-041-39/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | cook_args() and raw_args() do some peculiar things in order to avoid calling cook_buf() and raw_cat(), respectively, in more than one place. The result is a convoluted. If we isolate the special cases from the normal case and just call these functions in multiple places the loops will be easier to read. Three things: 1. Pull the no-args case out of the loop. If *argv is NULL when we get into the argv processing function we just want to operate on the standard input and return early. It makes no sense to handle this case *in* the loop. 2. Isolate the "-" case from the filename case. If *argv is "-" we want to operate on the standard input. We can then do any stdin-specific cleanup within the same branch, which makes it easier to understand both the "-" case and the normal filename case. This also allows us to remove the 'filename' intermediate variable from both argv processing functions. 3. While we're here, use a for-loop and iterate argv in the loop header. Now argv is incremented in one place. ok martijn@
* cat(1): remove global 'filename' variablecheloha2020-12-031-8/+9
| | | | | | | | There is no need for the global filename variable. Both cook_buf() and raw_cat() can accept a filename variable from the caller to use for printing warnings. ok martijn@
