It may be very handy to have something like ":mark-all" command

[denpy]

Hello,

When writing lnav scripts :mark command is handy, and having :mark-all command for marking all lines may be convenient, especially when :pipe-to command is used afterwards.

What do you think about this idea?

You can use the SQL interface to mark all of the lines, like so:

;UPDATE all_logs SET log_mark = 1;

However, marking all the lines is probably not going to be performant. I tend to expect bookmarks to be a small percentage of the number of lines, so I haven't spent much time optimizing it.

Can you share what higher-level operation you're trying to do and maybe we can find an alternate solution.

Essentially, I’d like to be able to process the entire file via the :pipe-to command for example when I work with some weird log file sometimes I want to leave the timestamp and message only (without hostname, level and other stuff). Usually, I accomplish this by marking all the lines and piping to cut or awk.

Alternatively, piping the file content without marking all the lines may do the job as well.

Have you tried the :hide-fields command? You can also write the whole contents of the view to a file with :write-view-to.

I'll look into adding support for piping content to a command.

Thank you! I'll check out the hide-fields command.
