| <start> and <end> can take one of these forms: | |
| - number | |
| + | |
| If <start> or <end> is a number, it specifies an | |
| absolute line number (lines count from 1). | |
| + | |
| - /regex/ | |
| + | |
| This form will use the first line matching the given | |
| POSIX regex. If <start> is a regex, it will search from the end of | |
| the previous `-L` range, if any, otherwise from the start of file. | |
| If <start> is ``^/regex/'', it will search from the start of file. | |
| If <end> is a regex, it will search | |
| starting at the line given by <start>. | |
| + | |
| - +offset or -offset | |
| + | |
| This is only valid for <end> and will specify a number | |
| of lines before or after the line given by <start>. | |
| + | |
| If ``:<funcname>'' is given in place of <start> and <end>, it is a | |
| regular expression that denotes the range from the first funcname line | |
| that matches <funcname>, up to the next funcname line. ``:<funcname>'' | |
| searches from the end of the previous `-L` range, if any, otherwise | |
| from the start of file. ``^:<funcname>'' searches from the start of | |
| file. |
