* Feature: highlight numbers of triggering lines.Kaz Kylheku2023-06-091-1/+10
| | | | | | | When a triggered snapshot is recorded, a flag is set in all the lines which matched the trigger patterns. Whenever highlighting is enabled, the line numbers of those lines are shown in inverse.
* Feature: implement pass-through mode.Kaz Kylheku2023-06-081-15/+51
| | | | | | | | | | | | | | | | | | | | In pass-through mode, pw can be used in the middle of a pipeline, or redirected to a file or device. Then instead of discarding data, it copies from standard input to standard output. pw's implementation assumes that standard output is the terminal, and uses some functions that operate implicitly on standard output. To avoid changing all that code, dup2 calls are used to rearrange the file descriptors. The tty descriptor opened from /dev/tty is installed as standard output, and the original standard output (the device, file or pipe to which data is to be passed through) is tied to a dedicated stream held in the local variable out. Whenever out is not null, bytes are to be sent to it rather than discarded. In pass-through mode, though, standard output is not the terminal.

* Fix regression: :E and :B commands not recognized.Kaz Kylheku2022-05-151-2/+7
|
* Tighten the command syntax.Kaz Kylheku2022-05-131-9/+26
| | | | | | | | | | Commands are now separated from their argument by exactly one space, which may only be omitted for an argument which does not begin with a letter. Thus :gfoo no longer pushes a regular expression foo onto the grep stack, but is the unrecognized command gfoo. The command :g foo specifies the regular expression " foo".
